Antisense modulation of interleukin-5 signal transduction

FIELD OF THE INVENTION
The present invention provides compositions and methods for modulating interleukin-5 (IL-5) signaling through antisense modulation of IL-5 and/or IL-5 receptor .alpha. (IL-5.alpha.) expression. In particular, this invention relates to antisense compounds, particularly oligonucleotides, specifically hybridizable with nucleic acids encoding IL-5 or IL-5R.alpha.. Such oligonucleotides have been shown to modulate the expression of IL-5 and IL-5R.alpha., respectively.
BACKGROUND OF THE INVENTION
Cytokines are relatively low molecular weight, pharmacologically active proteins that are secreted by cells for the purpose of altering either their own functions or those of adjacent cells. Cytokines are important regulators of hematopoiesis. They exert their actions by binding to specific receptors on the cell surface. Among the cytokines are a large number of interleukins as well as growth and colony-stimulating factors. Interleukin-5 (IL-5) is a critical cytokine for regulation of growth, activation, maturation, and survival of eosinophils, a type of leukocyte, and their release from the bone marrow. Eosinophils have been implicated in the pathogenesis of certain diseases ("eosinophilic syndromes") characterized by long-term chronic inflammation of tissues, such as the lungs in the case of asthma or the muscles in the case of eosinophilia myalgia. Other eosinophilic syndromes in addition to these include allergic rhinitis and atopic dermatitis. Eosinophils have also been noted as a component of cellular infiltrates of malignant tumors. Eosinophils are attracted to sites of wounding or inflammation, where they undergo a process of activation. Because eosinophils play a seminal role in the pathogenesis of asthma, particularly the late-phase reaction of asthma, and other inflammatory and/or allergic conditions, IL-5 signal transduction is of clinical importance.
In humans, IL-5 is selective in specifically promoting eosinophil and basophilic differentiation and maturation. Blood and tissue eosinophilia is a characteristic abnormality in allergy and asthma and convincing evidence implicates IL-5 as the key cytokine regulating this selective eosinophilic inflammation. Thus, inhibition of IL-5 production or effector function will abolish the eosinophilic component in asthma and other eosinophilic diseases, likely preventing further tissue damage caused by release of eosinophil-specific inflammatory mediators and potentially providing clinical benefit. Indeed, it has been demonstrated neutralizing IL-5 with a monoclonal antibody can completely inhibit bronchoalveolar eosinophilia caused by allergen challenge in guinea pigs, mice, and monkeys. A correlation exists between pulmonary eosinophilia and asthma in man and it is clear that selective inhibition of IL-5 can block airway hyperresponsiveness in animal models.
Asthma is characterized by episodic airways obstruction, increased bronchial hyperresponsiveness, and airway inflammation. An association has been shown between the number of activated T cells and eosinophils in the airways and abnormalities in forced expiratory volume in one second (FEV1), a measure of pulmonary function, increased bronchial responsiveness, and clinical severity in asthma. It has been documented that both interleukin-5 (IL-5) mRNA and protein levels are increased in bronchial biopsies from both atopic and intrinsic asthmatics.
IL-5 interacts with cells via the IL-5 receptor (IL-5R) on the cell surface. The IL-5 receptor is a heterodimer of .alpha.- and .beta.-subunits. The IL-5 receptor.alpha.-subunit is specific to IL-5R, whereas the .beta.-subunit is common to IL-3, IL-5, and granulocyte/macrophage colony-stimulating factor (GM-CSF) receptors. The human IL-5 receptor (IL-5R) is expressed in vitro on eosinophils, basophils, and B lymphocytes, although its role on B cells remains in question. Besides a membrane anchored form, two forms of soluble human IL-5R.alpha. are produced. Only the membrane form of the .alpha. chain is complexed with the .beta. chain, which is required for signaling.
The link between T cell derived IL-5 and lung eosinophilia is further strengthened by the observation that increased levels of IL-5 receptor.alpha. mRNA are also found in bronchial biopsies from asthmatics and that the eosinophil is the predominant site of this increased IL-5R.alpha. expression. Further, the subset of eosinophils that express the membrane bound form of the IL-5 receptor inversely correlates with FEV1 while the subset expressing the soluble form of the receptor directly correlates with FEV1. These observations suggest that IL-5 receptor.alpha. isoform expression is of central importance in determining clinical prognosis. The soluble form of the receptor may be serving a beneficial role in asthmatic patients. It is therefore presently believed that an effective therapeutic approach to preventing eosinophilia in asthma and other eosinophilic syndromes would entail selective inhibition of membrane but not soluble IL-5 receptor expression. In addition, there are several animal and lung explant models of allergen-induced eosinophilia, late phase airway responses, and bronchial hyperresponsiveness which collectively support a link between IL-5 and airway eosinophilia and decreased pulmonary function.
Several approaches to inhibition of IL-5 function have been tried. Chimeric, humanized and other interleukin-5 (IL-5) monoclonal antibodies (mAbs), and pharmaceutical compositions and therapeutic methods are disclosed in WO 96/21000. Ribozymes for cleaving IL-5 mRNA are disclosed in WO 95/23225. A 16mer phosphodiester oligo deoxynucleotide with two phosphorothioate linkages, targeted to IL-5 mRNA, was used to inhibit IL-5 secretion by human peripheral blood mononuclear cells. Weltman and Karim, Allergy Asthma Proc., 1998, 19, 257-261; September-October 1998. Methods of treating airway disease by administering essentially adenosine-free antisense oligonucleotides to the airway epithelium are disclosed in WO 96/40162. IL-5 and IL-5 receptor are among the antisense targets disclosed.
Thus there remains a long felt need for compositions and methods for modulating IL-5 signal transduction, particularly in the treatment and prevention of asthma and other reactive airway disease.

DETAILED DESCRIPTION OF THE INVENTION
The present invention comprehends antisense compounds capable of modulating IL-5 signal transduction, preferably by modulating expression of IL-5 or IL-5 receptor.alpha.. These compounds are useful for both research and therapeutic, including prophylactic, uses.
The human IL-5 receptor.alpha. gene contains 14 exons. A membrane-anchored form of the receptor and two soluble forms have been identified. The mRNA transcript encoding the membrane-anchored form of the human IL-5 receptor.alpha. contain exons 1-10 and 12-14. Exon 11 is spliced out by an alternative splicing event. The major soluble isoform (soluble form 1) is generated as a result of a normal splicing event and an in-frame stop codon in exon 11. The other soluble form (soluble form 2) is generated by the absence of splicing and therefore is generated by reading into intron 11. Tuypens et al. Eur. Cytokine Netw., 1992, 3, 451-459.
The mRNA encoding the membrane form of the mouse IL-5 receptor.alpha. contains 11 exons. The transmembrane domain of the receptor is encoded in exon 9. Two mRNAs encoding soluble (secreted) forms of the receptor result from differential splicing events. The mRNA encoding soluble form 1 of the receptor is missing exon 9 (exon 8 is spliced to exon 10) and the mRNA encoding soluble form 2 is missing exons 9 and 10 (exon 8 is spliced to exon 11). Imamura et al., DNA and Cell Biol., 1994, 13, 283-292.
In both mouse and humans, there are both soluble forms and a membrane-bound form of IL-5 receptor.alpha.. In mouse, the soluble form is expressed, though experiments are usually done by addition of exogenous recombinant soluble receptor. Recombinant murine soluble IL-5 receptor.alpha. binds IL-5, and does not inhibit proliferation of the IL-5-responsive Y16B cell line. In vivo, recombinant soluble murine IL-5 receptor.alpha. suppresses antigen-induced airway eosinophilia. In humans, recombinant human soluble IL-5 receptor.alpha. binds human IL-5 and inhibits its biological activity in vitro, i.e., prevents TF-1 proliferation and survival. In other words, in the human system, the soluble IL-5 receptor.alpha. acts as a sponge to bind the IL-5 cytokine and block its effects. Only the membrane-bound form of IL-5 receptor.alpha. is able to transduce the IL-5 signal. Soluble human IL-5 receptor.alpha. is not normally detected in human biological fluids; however, a direct correlation has been observed between the expression of soluble human IL-5 receptor.alpha. and pulmonary function in asthmatic subjects.
The present invention employs oligomeric antisense compounds, particularly oligonucleotides, for use in modulating IL-5 signal transduction. In preferred embodiments this is done by modulating the function of nucleic acid molecules encoding IL-5 or IL-5R.alpha., ultimately modulating the amount of IL-5 or IL-5R.alpha. produced. Antisense compounds are provided which specifically hybridize with one or more nucleic acids encoding IL-5 or IL-5R.alpha.. In preferred embodiments used herein, the term "nucleic acid encoding IL-5" encompasses DNA encoding IL-5, RNA (including pre-mRNA and mRNA) transcribed from such DNA, and also cDNA derived from such RNA. Similarly the term "nucleic acid encoding IL-5R.alpha." encompasses DNA encoding IL-5R.alpha., RNA (including pre-mRNA and mRNA) transcribed from such DNA, and also cDNA derived from such RNA. In the context of the present invention, the term "nucleic acid target" encompasses nucleic acids encoding either IL-5 or IL-5R.alpha., according to which of these the antisense compound is complementary. The specific hybridization of an oligomeric compound with its target nucleic acid interferes with the normal function of the nucleic acid. This modulation of function of a target nucleic acid by compounds which specifically hybridize to it is generally referred to as "antisense". The functions of DNA to be interfered with include replication and transcription. The functions of RNA to be interfered with include all vital functions such as, for example, translocation of the RNA to the site of protein translation, translation of protein from the RNA, splicing of the RNA to yield one or more mRNA species, and catalytic activity which may be engaged in or facilitated by the RNA. The overall effect of such interference with target nucleic acid function is modulation of the expression of IL-5 or IL-5R.alpha.. In the context of the present invention, "modulation" means either an increase (stimulation) or a decrease (inhibition) in the expression of a gene. In the context of the present invention, inhibition is the preferred form of modulation of gene expression and mRNA is a preferred target.
It is preferred to target specific nucleic acids for antisense. "Targeting" an antisense compound to a particular nucleic acid, in the context of this invention, is a multistep process. The process usually begins with the identification of a nucleic acid sequence whose function is to be modulated. This may be, for example, a cellular gene (or mRNA transcribed from the gene) whose expression is associated with a particular disorder or disease state, or a nucleic acid molecule from an infectious agent. In the present invention, the target is a nucleic acid molecule encoding IL-5 or IL-5R.alpha.. The targeting process also includes determination of a site or sites within this gene for the antisense interaction to occur such that the desired effect, e.g., detection or modulation of expression of the protein, will result. Within the context of the present invention, a preferred intragenic site is the region encompassing the translation initiation or termination codon of the open reading frame (ORF) of the gene. Since, as is known in the art, the translation initiation codon is typically 5'-AUG (in transcribed mRNA molecules; 5'-ATG in the corresponding DNA molecule), the translation initiation codon is also referred to as the "AUG codon," the "start codon" or the "AUG start codon". A minority of genes have a translation initiation codon having the RNA sequence 5'-GUG, 5'-UUG or 5'-CUG, and 5'-AUA, 5'-ACG and 5'-CUG have been shown to function in vivo. Thus, the terms "translation initiation codon" and "start codon" can encompass many codon sequences, even though the initiator amino acid in each instance is typically methionine (in eukaryotes) or formylmethionine (in prokaryotes). It is also known in the art that eukaryotic and prokaryotic genes may have two or more alternative start codons, any one of which may be preferentially utilized for translation initiation in a particular cell type or tissue, or under a particular set of conditions. In the context of the invention, "start codon" and "translation initiation codon" refer to the codon or codons that are used in vivo to initiate translation of an mRNA molecule transcribed from a gene encoding IL-5 or IL-5R.alpha., regardless of the sequence(s) of such codons.
It is also known in the art that a translation termination codon (or "stop codon") of a gene may have one of three sequences, i.e., 5'-UAA, 5'-UAG and 5'-UGA (the corresponding DNA sequences are 5'-TAA, 5'-TAG and 5'-TGA, respectively). The terms "start codon region" and "translation initiation codon region" refer to a portion of such an mRNA or gene that encompasses from about 25 to about 50 contiguous nucleotides in either direction (i.e., 5' or 3') from a translation initiation codon. Similarly, the terms "stop codon region" and "translation termination codon region" refer to a portion of such an mRNA or gene that encompasses from about 25 to about 50 contiguous nucleotides in either direction (i.e., 5' or 3') from a translation termination codon.
The open reading frame (ORF) or "coding region," which is known in the art to refer to the region between the translation initiation codon and the translation termination codon, is also a region which may be targeted effectively. Other target regions include the 5' untranslated region (5'UTR), known in the art to refer to the portion of an mRNA in the 5' direction from the translation initiation codon, and thus including nucleotides between the 5' cap site and the translation initiation codon of an mRNA or corresponding nucleotides on the gene, and the 3' untranslated region (3'UTR), known in the art to refer to the portion of an mRNA in the 3' direction from the translation termination codon, and thus including nucleotides between the translation termination codon and 3' end of an mRNA or corresponding nucleotides on the gene. The 5' cap of an mRNA comprises an N7-methylated guanosine residue joined to the 5'-most residue of the mRNA via a 5'-5' triphosphate linkage. The 5' cap region of an mRNA is considered to include the 5' cap structure itself as well as the first 50 nucleotides adjacent to the cap. The 5' cap region may also be a preferred target region.
Although some eukaryotic mRNA transcripts are directly translated, many contain one or more regions, known as "introns," which are excised from a transcript before it is translated. The remaining (and therefore translated) regions are known as "exons" and are spliced together to form a continuous mRNA sequence. mRNA splice sites, i.e., intron-exon junctions, may also be preferred target regions, and are particularly useful in situations where aberrant splicing is implicated in disease, or where an overproduction of a particular mRNA splice product is implicated in disease. Aberrant fusion junctions due to rearrangements or deletions are also preferred targets. It has also been found that introns can also be effective, and therefore preferred, target regions for antisense compounds targeted, for example, to DNA or pre-mRNA.
Once one or more target sites have been identified, oligonucleotides are chosen which are sufficiently complementary to the target, i.e., hybridize sufficiently well and with sufficient specificity, to give the desired effect.
In the context of this invention, "hybridization" means hydrogen bonding, which may be Watson-Crick, Hoogsteen or reversed Hoogsteen hydrogen bonding, between complementary nucleoside or nucleotide bases. For example, adenine and thymine are complementary nucleobases which pair through the formation of hydrogen bonds. "Complementary," as used herein, refers to the capacity for precise pairing between two nucleotides. For example, if a nucleotide at a certain position of an oligonucleotide is capable of hydrogen bonding with a nucleotide at the same position of a DNA or RNA molecule, then the oligonucleotide and the DNA or RNA are considered to be complementary to each other at that position. The oligonucleotide and the DNA or RNA are complementary to each other when a sufficient number of corresponding positions in each molecule are occupied by nucleotides which can hydrogen bond with each other. Thus, "specifically hybridizable" and "complementary" are terms which are used to indicate a sufficient degree of complementarity or precise pairing such that stable and specific binding occurs between the oligonucleotide and the DNA or RNA target. It is understood in the art that the sequence of an antisense compound need not be 100% complementary to that of its target nucleic acid to be specifically hybridizable. An antisense compound is specifically hybridizable when binding of the compound to the target DNA or RNA molecule interferes with the normal function of the target DNA or RNA to cause a loss of utility, and there is a sufficient degree of complementarity to avoid non-specific binding of the antisense compound to non-target sequences under conditions in which specific binding is desired, i.e., under physiological conditions in the case of in vivo assays or therapeutic treatment, and, in the case of in vitro assays, under conditions in which the assays are performed.
Antisense compounds are commonly used as research reagents and diagnostics. For example, antisense oligonucleotides, which are able to inhibit gene expression with exquisite specificity, are often used by those of ordinary skill to elucidate the function of particular genes. Antisense compounds are also used, for example, to distinguish between functions of various members of a biological pathway. Antisense modulation has, therefore, been harnessed for research use.
The specificity and sensitivity of antisense is also harnessed by those of skill in the art for therapeutic uses. Antisense oligonucleotides have been employed as therapeutic moieties in the treatment of disease states in animals and man. Antisense oligonucleotides have been safely and effectively administered to humans and numerous clinical trials are presently underway. It is thus established that oligonucleotides can be useful therapeutic modalities that can be configured to be useful in treatment regimes of cells, tissues and animals, especially humans. In the context of this invention, the term "oligonucleotide" refers to an oligomer or polymer of ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) or mimetics thereof. This term includes oligonucleotides composed of naturally-occurring nucleobases, sugars and covalent internucleoside (backbone) linkages as well as oligonucleotides having non-naturally-occurring portions which function similarly. Such modified or substituted oligonucleotides are often preferred over native forms because of desirable properties such as, for example, enhanced cellular uptake, enhanced affinity for nucleic acid target and increased stability in the presence of nucleases.
While antisense oligonucleotides are a preferred form of antisense compound, the present invention comprehends other oligomeric antisense compounds, including but not limited to oligonucleotide mimetics such as are described below. The antisense compounds in accordance with this invention preferably comprise from about 8 to about 30 nucleobases. Particularly preferred are antisense oligonucleotides comprising from about 8 to about 30 nucleotides). As is known in the art, a nucleoside is a base-sugar combination. The base portion of the nucleoside is normally a heterocyclic base. The two most common classes of such heterocyclic bases are the purines and the pyrimidines. Nucleotides are nucleosides that further include a phosphate group covalently linked to the sugar portion of the nucleoside. For those nucleosides that include a pentofuranosyl sugar, the phosphate group can be linked to either the 2'-, 3'- or 5'-hydroxyl moiety of the sugar. In forming oligonucleotides, the phosphate groups covalently link adjacent nucleosides to one another to form a linear polymeric compound. In turn the respective ends of this linear polymeric structure can be further joined to form a circular structure. However, open linear structures are generally preferred. Within the oligonucleotide structure, the phosphate groups are commonly referred to as forming the internucleoside backbone of the oligonucleotide. The normal linkage or backbone of RNA and DNA is a 3' to 5' phosphodiester linkage.
Specific examples of preferred antisense compounds useful in this invention include oligonucleotides containing modified backbones or non-natural internucleoside linkages. As defined in this specification, oligonucleotides having modified backbones include those that retain a phosphorus atom in the backbone and those that do not have a phosphorus atom in the backbone. For the purposes of this specification, and as sometimes referenced in the art, modified oligonucleotides that do not have a phosphorus atom in their internucleoside backbone can also be considered to be oligonucleosides.
Preferred modified oligonucleotide backbones include, for example, phosphorothioates, chiral phosphorothioates, phosphorodithioates, phosphotriesters, aminoalkylphosphotriesters, methyl and other alkyl phosphonates including 3'-alkylene phosphonates and chiral phosphonates, phosphinates, phosphoramidates including 3'-amino phosphoramidate and aminoalkylphosphoramidates, thionophosphoramidates, thionoalkylphosphonates, thionoalkylphosphotriesters, and boranophosphates having normal 3'-5' linkages, 2'-5' linked analogs of these, and those having inverted polarity wherein the adjacent pairs of nucleoside units are linked 3'-5' to 5'-3' or 2'-5' to 5'-2'. Various salts, mixed salts and free acid forms are also included.
Representative United States patents that teach the preparation of the above phosphorus-containing linkages include, but are not limited to, U.S. Pat. Nos.: 3,687,808; 4,469,863; 4,476,301; 5,023,243; 5,177,196; 5,188,897; 5,264,423; 5,276,019; 5,278,302; 5,286,717; 5,321,131; 5,399,676; 5,405,939; 5,453,496; 5,455,233; 5,466,677; 5,476,925; 5,519,126; 5,536,821; 5,541,306; 5,550,111; 5,563,253; 5,571,799; 5,587,361; and 5,625,050, each of which is herein incorporated by reference.
Preferred modified oligonucleotide backbones that do not include a phosphorus atom therein have backbones that are formed by short chain alkyl or cycloalkyl internucleoside linkages, mixed heteroatom and alkyl or cycloalkyl internucleoside linkages, or one or more short chain heteroatomic or heterocyclic internucleoside linkages. These include those having morpholino linkages (formed in part from the sugar portion of a nucleoside); siloxane backbones; sulfide, sulfoxide and sulfone backbones; formacetyl and thioformacetyl backbones; methylene formacetyl and thioformacetyl backbones; alkene containing backbones; sulfamate backbones; methyleneimino and methylenehydrazino backbones; sulfonate and sulfonamide backbones; amide backbones; and others having mixed N, O, S and CH.sub.2 component parts.

Nos.: 5,034,506; 5,166,315; 5,185,444; 5,214,134; 5,216,141; 5,235,033; 5,264,562; 5,264,564; 5,405,938; 5,434,257; 5,466,677; 5,470,967; 5,489,677; 5,541,307; 5,561,225; 5,596,086; 5,602,240; 5,610,289; 5,602,240; 5,608,046; 5,610,289; 5,618,704; 5,623,070; 5,663,312; 5,633,360; 5,677,437; and 5,677,439, each of which is herein incorporated by reference.
In other preferred oligonucleotide mimetics, both the sugar and the internucleoside linkage, i.e., the backbone, of the nucleotide units are replaced with novel groups. The base units are maintained for hybridization with an appropriate nucleic acid target compound. One such oligomeric compound, an oligonucleotide mimetic that has been shown to have excellent hybridization properties, is referred to as a peptide nucleic acid (PNA). In PNA compounds, the sugar-backbone of an oligonucleotide is replaced with an amide containing backbone, in particular an aminoethyiglycine backbone. The nucleobases are retained and are bound directly or indirectly to aza nitrogen atoms of the amide portion of the backbone. Representative United States patents that teach the preparation of PNA compounds include, but are not limited to, U.S. Pat. Nos.: 5,539,082; 5,714,331; and 5,719,262, each of which is herein incorporated by reference. Further teaching of PNA compounds can be found in Nielsen et al., Science, 1991, 254, 1497-1500.

It is not necessary for all positions in a given compound to be uniformly modified, and in fact more than one of the aforementioned modifications may be incorporated in a single compound or even at a single nucleoside within an oligonucleotide. The present invention also includes antisense compounds which are chimeric compounds. "Chimeric" antisense compounds or "chimeras," in the context of this invention, are antisense compounds, particularly oligonucleotides, which contain two or more chemically distinct regions, each made up of at least one monomer unit, i.e., a nucleotide in the case of an oligonucleotide compound. These oligonucleotides typically contain at least one region wherein the oligonucleotide is modified so as to confer upon the oligonucleotide increased resistance to nuclease degradation, increased cellular uptake, and/or increased binding affinity for the target nucleic acid. An additional region of the oligonucleotide may serve as a substrate for enzymes capable of cleaving RNA:DNA or RNA:RNA hybrids. By way of example, RNase H is a cellular endonuclease which cleaves the RNA strand of an RNA:DNA duplex. Activation of RNase H, therefore, results in cleavage of the RNA target, thereby greatly enhancing the efficiency of oligonucleotide inhibition of gene expression. Cleavage of the RNA target can be routinely detected by gel electrophoresis and, if necessary, associated nucleic acid hybridization techniques known in the art.
Chimeric antisense compounds of the invention may be formed as composite structures of two or more oligonucleotides, modified oligonucleotides, oligonucleosides and/or oligonucleotide mimetics as described above. Such compounds have also been referred to in the art as hybrids or gapmers. Representative United States patents that teach the preparation of such hybrid structures include, but are not limited to, U.S. Pat. Nos.: 5,013,830; 5,149,797; 5,220,007; 5,256,775; 5,366,878; 5,403,711; 5,491,133; 5,565,350; 5,623,065; 5,652,355; 5,652,356; and 5,700,922, each of which is herein incorporated by reference.
The antisense compounds used in accordance with this invention may be conveniently and routinely made through the well-known technique of solid phase synthesis. Equipment for such synthesis is sold by several vendors including, for example, Applied Biosystems (Foster City, Calif.). Any other means for such synthesis known in the art may additionally or alternatively be employed. It is well known to use similar techniques to prepare oligonucleotides such as the phosphorothioates and alkylated derivatives.
The antisense compounds of the invention are synthesized in vitro and do not include antisense compositions of biological origin, or genetic vector constructs designed to direct the in vivo synthesis of antisense molecules.
The compounds of the invention may also be admixed, encapsulated, conjugated or otherwise associated with other molecules, molecule structures or mixtures of compounds, as for example, liposomes, receptor targeted molecules, oral, rectal, topical or other formulations, for assisting in uptake, distribution and/or absorption. Representative United States patents that teach the preparation of such uptake, distribution and/or absorption assisting formulations include, but are not limited to, U.S. Pat. Nos.: 5,108,921; 5,354,844; 5,416,016; 5,459,127; 5,521,291; 5,543,158; 5,547,932; 5,583,020; 5,591,721; 4,426,330; 4,534,899; 5,013,556; 5,108,921; 5,213,804; 5,227,170; 5,264,221; 5,356,633; 5,395,619; 5,416,016; 5,417,978; 5,462,854; 5,469,854; 5,512,295; 5,527,528; 5,534,259; 5,543,152; 5,556,948; 5,580,575; and 5,595,756, each of which is herein incorporated by reference.
The antisense compounds of the invention encompass any pharmaceutically acceptable salts, esters, or salts of such esters, or any other compound which, upon administration to an animal including a human, is capable of providing (directly or indirectly) the biologically active metabolite or residue thereof. Accordingly, for example, the disclosure is also drawn to prodrugs and pharmaceutically acceptable salts of the compounds of the invention, pharmaceutically acceptable salts of such prodrugs, and other bioequivalents.
The term "prodrug" indicates a therapeutic agent that is prepared in an inactive form that is converted to an active form (i.e., drug) within the body or cells thereof by the action of endogenous enzymes or other chemicals and/or conditions. In particular, prodrug versions of the oligonucleotides of the invention are prepared as SATE [(S-acetyl-2-thioethyl)phosphate] derivatives according to the methods disclosed in WO 93/24510 or in WO 94/26764.
The term "pharmaceutically acceptable salts" refers to physiologically and pharmaceutically acceptable salts of the compounds of the invention: i.e., salts that retain the desired biological activity of the parent compound and do not impart undesired toxicological effects thereto.
Pharmaceutically acceptable base addition salts are formed with metals or amines, such as alkali and alkaline earth metals or organic amines. Examples of metals used as cations are sodium, potassium, magnesium, calcium, and the like. Examples of suitable amines are N,N'-dibenzylethylenediamine, chloroprocaine, choline, diethanolamine, dicyclohexylamine, ethylenediamine, N-methylglucamine, and procaine (see, for example, Berge et al., "Pharmaceutical Salts," J. of Pharma Sci., 1977, 66, 1-19). The base addition salts of said acidic compounds are prepared by contacting the free acid form with a sufficient amount of the desired base to produce the salt in the conventional manner. The free acid form may be regenerated by contacting the salt form with an acid and isolating the free acid in the conventional manner. The free acid forms differ from their respective salt forms somewhat in certain physical properties such as solubility in polar solvents, but otherwise the salts are equivalent to their respective free acid for purposes of the present invention. As used herein, a "pharmaceutical addition salt" includes a pharmaceutically acceptable salt of an acid form of one of the components of the compositions of the invention. These include organic or inorganic acid salts of the amines. Preferred addition salts are acid salts such as the hydrochlorides, acetates, salicylates, nitrates and phosphates. Other suitable pharmaceutically acceptable salts are well known to those skilled in the art and include basic salts of a variety of inorganic and organic acids, such as, for example, with inorganic acids, such as for example hydrochloric acid, hydrobromic acid, sulfuric acid or phosphoric acid; with organic carboxylic, sulfonic, sulfo or phospho acids or N-substituted sulfamic acids, for example acetic acid, propionic acid, glycolic acid, succinic acid, maleic acid, hydroxymaleic acid, methylmaleic acid, fumaric acid, malic acid, tartaric acid, lactic acid, oxalic acid, gluconic acid, glucaric acid, glucuronic acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, salicylic acid, 4-aminosalicylic acid, 2-phenoxybenzoic acid, 2-acetoxybenzoic acid, embolic acid, nicotinic acid or isonicotinic acid; and with amino acids, such as the 20 alpha-amino acids involved in the synthesis of proteins in nature, for example glutamic acid or aspartic acid, and also with phenylacetic acid, methanesulfonic acid, ethanesulfonic acid, 2-hydroxyethanesulfonic acid, ethane-1,2-disulfonic acid, benzenesulfonic acid, 4-methylbenzenesulfoic acid, naphthalene-2-sulfonic acid, naphthalene-1,5-disulfonic acid, 2- or 3-phosphoglycerate, glucose-6-phosphate, N-cyclohexylsulfamic acid (with the formation of cyclamates), or with other acid organic compounds, such as ascorbic acid. Pharmaceutically acceptable salts of compounds may also be prepared with a pharmaceutically acceptable cation. Suitable pharmaceutically acceptable cations are well known to those skilled in the art and include alkaline, alkaline earth, ammonium and quaternary ammonium cations. Carbonates or hydrogen carbonates are also possible.
For oligonucleotides, preferred examples of pharmaceutically acceptable salts include but are not limited to (a) salts formed with cations such as sodium, potassium, ammonium, magnesium, calcium, polyamines such as spermine and spermidine, etc.; (b) acid addition salts formed with inorganic acids, for example hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, nitric acid and the like; (c) salts formed with organic acids such as, for example, acetic acid, oxalic acid, tartaric acid, succinic acid, maleic acid, fumaric acid, gluconic acid, citric acid, malic acid, ascorbic acid, benzoic acid, tannic acid, palmitic acid, alginic acid, polyglutamic acid, naphthalenesulfonic acid, methanesulfonic acid, p-toluenesulfonic acid, naphthalenedisulfonic acid, polygalacturonic acid, and the like; and (d) salts formed from elemental anions such as chlorine, bromine, and iodine.
The antisense compounds of the present invention can be utilized for diagnostics, therapeutics, prophylaxis and as research reagents and kits. For therapeutics, an animal, preferably a human, suspected of having a disease or disorder which can be treated by modulating IL-5 signaling is treated by administering one or more antisense compounds in accordance with this invention. The compounds of the invention can be utilized in pharmaceutical compositions by adding an effective amount of an antisense compound to a suitable pharmaceutically acceptable diluent or carrier. Use of the antisense compounds and methods of the invention may also be useful prophylactically, e.g., to prevent or delay infection, inflammation or tumor formation, for example.
The antisense compounds of the invention are useful for research and diagnostics, because these compounds hybridize to nucleic acids encoding IL-5 or IL-5R.alpha., enabling sandwich and other assays to easily be constructed to exploit this fact. Hybridization of the antisense oligonucleotides of the invention with a nucleic acid encoding IL-5 or IL-5R.alpha. can be detected by means known in the art. Such means may include conjugation of an enzyme to the oligonucleotide, radiolabelling of the oligonucleotide or any other suitable detection means. Kits using such detection means for detecting the level of IL-5 or IL-5R.alpha. in a sample may also be prepared.
The present invention also includes pharmaceutical compositions and formulations which include the antisense compounds of the invention. The pharmaceutical compositions of the present invention may be administered in a number of ways depending upon whether local or systemic treatment is desired and upon the area to be treated. Administration may be topical (including ophthalmic and to mucous membranes including vaginal and rectal delivery), pulmonary, e.g., by inhalation or insufflation of powders or aerosols, including by nebulizer; intratracheal, intranasal, epidermal and transdermal), oral or parenteral. Parenteral administration includes intravenous, intraarterial, subcutaneous, intraperitoneal or intramuscular injection or infusion; or intracranial, e.g., intrathecal or intraventricular, administration. Oligonucleotides with at least one 2'-O-methoxyethyl modification are believed to be particularly useful for oral administration.
Pharmaceutical compositions and formulations for topical administration may include transdermal patches, ointments, lotions, creams, gels, drops, suppositories, sprays, liquids and powders. Conventional pharmaceutical carriers, aqueous, powder or oily bases, thickeners and the like may be necessary or desirable. Coated condoms, gloves and the like may also be useful.
Compositions and formulations for oral administration include powders or granules, suspensions or solutions in water or non-aqueous media, capsules, sachets or tablets. Thickeners, flavoring agents, diluents, emulsifiers, dispersing aids or binders may be desirable.
Compositions and formulations for parenteral, intrathecal or intraventricular administration may include sterile aqueous solutions which may also contain buffers, diluents and other suitable additives such as, but not limited to, penetration enhancers, carrier compounds and other pharmaceutically acceptable carriers or excipients.
Pharmaceutical compositions and/or formulations comprising the oligonucleotides of the present invention may also include penetration enhancers in order to enhance the alimentary delivery of the oligonucleotides. Penetration enhancers may be classified as belonging to one of five broad categories, i.e., fatty acids, bile salts, chelating agents, surfactants and non-surfactants (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, 8, 91-192; Muranishi, Critical Reviews in Therapeutic Drug Carrier Systems, 1990, 7, 1-33). One or more penetration enhancers from one or more of these broad categories may be included.
Various fatty acids and their derivatives which act as penetration enhancers include, for example, oleic acid, lauric acid, capric acid, myristic acid, palmitic acid, stearic acid, linoleic acid, linolenic acid, dicaprate, tricaprate, recinleate, monoolein (a.k.a. 1-monooleoyl-rac-glycerol), dilaurin, caprylic acid, arichidonic acid, glyceryl 1-monocaprate, 1-dodecylazacycloheptan-2-one, acylcarnitines, acylcholines, mono- and di-glycerides and physiologically acceptable salts thereof (i.e., oleate, laurate, caprate, myristate, palmitate, stearate, linoleate, etc.) (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, 8:2, 91-192; Muranishi, Critical Reviews in Therapeutic Drug Carrier Systems, 1990, 7:1, 1-33; El-Hariri et al., J. Pharm. Pharmacol., 1992, 44, 651-654). Examples of some presently preferred fatty acids are sodium caprate and sodium laurate, used singly or in combination at concentrations of 0.5 to 5%.
The physiological roles of bile include the facilitation of dispersion and absorption of lipids and fat-soluble vitamins (Brunton, Chapter 38 In: Goodman & Gilman's The Pharmacological Basis of Therapeutics, 9th Ed., Hardman et al., eds., McGraw-Hill, New York, N.Y., 1996, pages 934-935). Various natural bile salts, and their synthetic derivatives, act as penetration enhancers. Thus, the term "bile salt" includes any of the naturally occurring components of bile as well as any of their synthetic derivatives. A presently preferred bile salt is chenodeoxycholic acid (CDCA) (Sigma Chemical Company, St. Louis, Mo.), generally used at concentrations of 0.5 to 2%.
Complex formulations comprising one or more penetration enhancers may be used. For example, bile salts may be used in combination with fatty acids to make complex formulations. Preferred combinations include CDCA combined with sodium caprate or sodium laurate (generally 0.5 to 5%).
Chelating agents include, but are not limited to, disodium ethylenediaminetetraacetate (EDTA), citric acid, salicylates (e.g., sodium salicylate, 5-methoxysalicylate and homovanilate), N-acyl derivatives of collagen, laureth-9 and N-amino acyl derivatives of beta-diketones (enamines) (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, 8:2, 92-192; Muranishi, Critical Reviews in Therapeutic Drug Carrier Systems, 1990, 7:1, 1-33; Buur et al., J. Control Rel., 1990, 14, 43-51). Chelating agents have the added advantage of also serving as DNase inhibitors.
Surfactants include, for example, sodium lauryl sulfate, polyoxyethylene-9-lauryl ether and polyoxyethylene-20-cetyl ether (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, 8:2, 92-191); and perfluorochemical emulsions, such as FC-43 (Takahashi et al., J. Pharm. Pharmacol., 1988, 40, 252-257).
Non-surfactants include, for example, unsaturated cyclic ureas, 1-alkyl- and 1-alkenylazacyclo-alkanone derivatives (Lee et al., Critical Reviews in Therapeutic Drug Carrier Systems, 1991, 8:2, 92-191); and non-steroidal anti-inflammatory agents such as diclofenac sodium, indomethacin and phenylbutazone (Yamashita et al., J. Pharm. Pharmacol., 1987, 39, 621-626).
As used herein, "carrier compound" refers to a nucleic acid, or analog thereof, which is inert (i.e., does not possess biological activity per se) but is recognized as a nucleic acid by in vivo processes that reduce the bioavailability of a nucleic acid having biological activity by, for example, degrading the biologically active nucleic acid or promoting its removal from circulation. The coadministration of a nucleic acid and a carrier compound, typically with an excess of the latter substance, can result in a substantial reduction of the amount of nucleic acid recovered in the liver, kidney or other extracirculatory reservoirs, presumably due to competition between the carrier compound and the nucleic acid for a common receptor. For example, the recovery of a partially phosphorothioated oligonucleotide in hepatic tissue is reduced when it is coadministered with polyinosinic acid, dextran sulfate, polycytidic acid or 4-acetamido-4'-isothiocyano-stilbene-2,2'-disulfonic acid (Miyao et al., Antisense Res. Dev., 1995, 5, 115-121; Takakura et al., Antisense & Nucl. Acid Drug Dev., 1996, 6, 177-183).
In contrast to a carrier compound, a "pharmaceutically acceptable carrier" (excipient) is a pharmaceutically acceptable solvent, suspending agent or any other pharmacologically inert vehicle for delivering one or more nucleic acids to an animal. The pharmaceutically acceptable carrier may be liquid or solid and is selected with the planned manner of administration in mind so as to provide for the desired bulk, consistency, etc., when combined with a nucleic acid and the other components of a given pharmaceutical composition. Typical pharmaceutically acceptable carriers include, but are not limited to, binding agents (e.g., pregelatinized maize starch, polyvinylpyrrolidone or hydroxypropyl methylcellulose, etc.); fillers (e.g., lactose and other sugars, microcrystalline cellulose, pectin, gelatin, calcium sulfate, ethyl cellulose, polyacrylates or calcium hydrogen phosphate, etc.); lubricants (e.g., magnesium stearate, talc, silica, colloidal silicon dioxide, stearic acid, metallic stearates, hydrogenated vegetable oils, corn starch, polyethylene glycols, sodium benzoate, sodium acetate, etc.); disintegrates (e.g., starch, sodium starch glycolate, etc.); or wetting agents (e.g., sodium lauryl sulphate, etc.). Sustained release oral delivery systems and/or enteric coatings for orally administered dosage forms are described in U.S. Pat. Nos. 4,704,295; 4,556,552; 4,309,406; and 4,309,404.
The compositions of the present invention may additionally contain other adjunct components conventionally found in pharmaceutical compositions, at their art-established usage levels. Thus, for example, the compositions may contain additional compatible pharmaceutically-active materials such as, e.g., antipruritics, astringents, local anesthetics or anti-inflammatory agents, or may contain additional materials useful in physically formulating various dosage forms of the composition of present invention, such as dyes, flavoring agents, preservatives, antioxidants, opacifiers, thickening agents and stabilizers. However, such materials, when added, should not unduly interfere with the biological activities of the components of the compositions of the invention.
In certain embodiments of this invention, the antisense compounds of the invention may be administered in combination with a conventional anti-asthma medication. Typically, two types of medication are used in attempts to control asthma: quick-relief medications (short-acting bronchodilators) that work fast to stop attacks or relieve symptoms and long-term preventive medications (especially anti-inflammatory agents) that keep symptoms and attacks from starting. Examples of the short-acting bronchodilators are short-acting .beta.2-agonists, for example, albuterol, bitolterol, fenoterol isoetharine, metaproterenol, pirbuterol, salbutamol and terbutaline; anticholinergics, for example ipratropium bromide and oxitropium bromide; short-acting theophyllines, for example, aminophylline; and epinephrine/adrenaline. Examples of long-term preventive medications are inhaled or oral corticosteroids, for example, beclomethasone, budesonide, fluticasone triamcinolone, prednisolone, prednisone and methylprednisolone; sodium cromoglycate or cromolyn sodium; nedocromil; oral or inhaled long-acting .beta.2-agonists, for example salmeterol, formoterol, terbutaline, salbutamol; sustained-release theophyllines, for example, aminophylline, methylxanthine and xanthine; and ketotifen. Antisense compounds of the present inventions may be administered in combination or conjunction with these or any of the asthma medications known in the art.
The compounds of the invention may also be administered in combination with another inhibitor of IL-5 signal transduction, preferably an antibody directed to IL-5. Such antibodies are known in the art.
Regardless of the method by which the antisense compounds of the invention are introduced into a patient, colloidal dispersion systems may be used as delivery vehicles to enhance the in vivo stability of the compounds and/or to target the compounds to a particular organ, tissue or cell type. Colloidal dispersion systems include, but are not limited to, macromolecule complexes, nanocapsules, microspheres, beads and lipid-based systems including oil-in-water emulsions, micelles, mixed micelles, liposomes and lipid:oligonucleotide complexes of uncharacterized structure. A preferred colloidal dispersion system is a plurality of liposomes. Liposomes are microscopic spheres having an aqueous core surrounded by one or more outer layer(s) made up of lipids arranged in a bilayer configuration (see, generally, Chonn et al., Current Op. Biotech., 1995, 6, 698-708).
Certain embodiments of the invention provide for liposomes and other compositions containing (a) one or more antisense compounds and (b) one or more other chemotherapeutic agents which function by a non-antisense mechanism. Examples of such chemotherapeutic agents include, but are not limited to, anticancer drugs such as daunorubicin, dactinomycin, doxorubicin, bleomycin, mitomycin, nitrogen mustard, chlorambucil, melphalan, cyclophosphamide, 6-mercaptopurine, 6-thioguanine, cytarabine (CA), 5-fluorouracil (5-FU), floxuridine (5-FUdR), methotrexate (MTX), coichicine, vincristine, vinblastine, etoposide, teniposide, cisplatin and diethylstilbestrol (DES). See, generally, The Merck Manual of Diagnosis and Therapy, 15th Ed., Berkow et al., eds., 1987, Rahway, N.J., pp. 1206-1228. Anti-inflammatory drugs, including but not limited to nonsteroidal anti-inflammatory drugs and corticosteroids, and antiviral drugs, including but not limited to ribovirin, vidarabine, acyclovir and ganciclovir, may also be combined in compositions of the invention. See, generally, The Merck Manual of Diagnosis and Therapy, 15th Ed., Berkow et al., eds., 1987, Rahway, N.J., pp. 2499-2506 and 46-49, respectively. Other non-antisense chemotherapeutic agents are also within the scope of this invention. Two or more combined compounds may be used together or sequentially.
In another related embodiment, compositions of the invention may contain one or more antisense compounds, particularly oligonucleotides, targeted to a first nucleic acid and one or more additional antisense compounds targeted to a second nucleic acid target. Two or more combined compounds may be used together or sequentially.
The formulation of therapeutic compositions and their subsequent administration is believed to be within the skill of those in the art. Dosing is dependent on severity and responsiveness of the disease state to be treated, with the course of treatment lasting from several days to several months, or until a cure is effected or a diminution of the disease state is achieved. Optimal dosing schedules can be calculated from measurements of drug accumulation in the body of the patient. Persons of ordinary skill can easily determine optimum dosages, dosing methodologies and repetition rates. Optimum dosages may vary depending on the relative potency of individual oligonucleotides, and can generally be estimated based on EC.sub.50 s found to be effective in in vitro and in viva animal models. In general, dosage is from 0.01 .mu.g to 100 g per kg of body weight, and may be given once or more daily, weekly, monthly or yearly, or even once every 2 to 20 years. Persons of ordinary skill in the art can easily estimate repetition rates for dosing based on measured residence times and concentrations of the drug in bodily fluids or tissues. Following successful treatment, it may be desirable to have the patient undergo maintenance therapy to prevent the recurrence of the disease state, wherein the oligonucleotide is administered in maintenance doses, ranging from 0.01 .mu.g to 100 g per kg of body weight, once or more daily, to once every 20 years.

While the present invention has been described with specificity in accordance with certain of its preferred embodiments, the following examples serve only to illustrate the invention and are not intended to limit the same.
EXAMPLES
Example 1
Nucleoside Phosphoramidites for Oligonucleotide Synthesis Deoxy and 2'-alkoxy Amidites
2'-Deoxy and 2'-methoxy .beta.-cyanoethyldiisopropyl phosphoramidites were purchased from commercial sources (e.g. Chemgenes, Needham Mass. or Glen Research, Inc. Sterling Va.). Other 2'-O-alkoxy substituted nucleoside amidites are prepared as described in U.S. Pat. No. 5,506,351, herein incorporated by reference. For oligonucleotides synthesized using 2'-alkoxy amidites, the standard cycle for unmodified oligonucleotides was utilized, except the wait step after pulse delivery of tetrazole and base was increased to 360 seconds.
Oligonucleotides containing 5-methyl-2'-deoxycytidine (5-Me-C) nucleotides were synthesized according to published methods (Sanghvi, et. al., Nucleic Acids Research, 1993, 21, 3197-3203] using commercially available phosphoramidites (Glen Research, Sterling Va. or ChemGenes, Needham Mass.).
2'-Fluoro Amidites
2'-Fluorodeoxyadenosine Amidites
2'-fluoro oligonucleotides are synthesized as described previously by Kawasaki, et. al., J. Med. Chem., 1993, 36, 831-841 and U.S. Pat. No. 5,670,633, herein incorporated by reference. Briefly, the protected nucleoside N6-benzoyl-2'-deoxy-2'-fluoroadenosine is synthesized utilizing commercially available 9-beta-D-arabinofuranosyladenine as starting material and by modifying literature procedures whereby the 2'-alpha-fluoro atom is introduced by a S.sub.N 2-displacement of a 2'-beta-trityl group. Thus N6-benzoyl-9-beta-D-arabinofuranosyladenine was selectively protected in moderate yield as the 3',5'-ditetrahydropyranyl (THP) intermediate. Deprotection of the THP and N6-benzoyl groups is accomplished using standard methodologies and standard methods are used to obtain the 5'-dimethoxytrityl-(DMT) and 5'-DMT-3'-phosphoramidite intermediates.
2'-Fluorodeoxyguanosine
The synthesis of 2'-deoxy-2'-fluoroguanosine is accomplished using tetraisopropyldisiloxanyl (TPDS) protected 9-beta-D-arabinofuranosylguanine as starting material, and conversion to the intermediate diisobutyryl-arabinofuranosylguanosine. Deprotection of the TPDS group is followed by protection of the hydroxyl group with THP to give diisobutyryl di-THP protected arabinofuranosylguanine. Selective O-deacylation and triflation is followed by treatment of the crude product with fluoride, then deprotection of the THP groups. Standard methodologies are used to obtain the 5'-DMT- and 5'-DMT-3'-phosphoramidites.
2'-Fluorouridine
Synthesis of 2'-deoxy-2'-fluorouridine is accomplished by the modification of a literature procedure in which 2,2'-anhydro-1-beta-D-arabinofuranosyluracil is treated with 70% hydrogen fluoride-pyridine. Standard procedures were used to obtain the 5'-DMT and 5'-DMT-3'phosphoramidites.
2'-Fluorodeoxycytidine
2'-deoxy-2'-fluorocytidine is synthesized via amination of 2'-deoxy-2'-fluorouridine, followed by selective protection to give N4-benzoyl-2'-deoxy-2'-fluorocytidine. Standard procedures are used to obtain the 5'-DMT and 5'-DMT-3'phosphoramidites.

Oligonucleotides were tested in EL-4 T cells (ATCC TIB-39, American Type Culture Collection, Manassas Va.) by Northern blot analysis as described in previous examples using a commercially available murine IL-5 probe. These cells are PHA responsive and PMA plus cAMP elevating agents induce a several hundredfold increase in IL-5 synthesis by these cells. Cells were maintained and stimulated to express IL-5 according to published methods and transfected with oligonucleotide via electroporation.
Oligonucleotides were tested at a concentration of 10 .mu.M. The results are shown in Table 2:

SEQ ID NO 8, 9, 10, 19 and 26 (ISIS 16981, 16982, 16983, 16992 and 16999, respectively) showed at least 30% inhibition of IL-5 expression in this assay and are therefore preferred.
Example 11
Dose Response Comparison of ISIS 16992 and 16999 for Reduction of Murine IL-5 mRNA Levels
ISIS 16992 and 16999 (SEQ ID NO: 19 and 26, respectively) were screened at concentrations of 5 to 25 .mu.M in EL-4 T cells for the ability to decrease IL-5 mRNA levels. Oligonucleotides were introduced to cells by electroporation and mRNA levels were measured by Northern blot analysis.
An IC50 (oligonucleotide concentration at which mRNA was decreased by 50% compared to control) of approximately 15 .mu.M was obtained for ISIS 16992 and approximately 18 .mu.M for ISIS 16999.
ISIS 16999 was compared to 1, 3, and 5-mismatch control sequences (ISIS Nos 17983, 17984 and 17985; SEQ ID Nos: 30, 31 and 32, respectively) in dose-response measurements of IL-5 mRNA levels after oligonucleotide treatment. In this experiment ISIS 16999 had an IC50 of approximately 9 .mu.M and ISIS 17983, the 1-base mismatch control, had an IC50 of approximately 13 .mu.M. IC50s were not obtainable for the 3- and 5-base mismatch controls which reduced IL-5 mRNA levels only by 8% and 17%, respectively.
Example 12
Dose Response Comparison of ISIS 16992 and 16999 for Reduction of Murine IL-5 Protein Levels
ISIS 16992 and 16999 (SEQ ID NO: 19 and 26, respectively) were screened at concentrations of 5 to 25 .mu.M in EL-4 T cells for the ability to decrease IL-5 protein levels. Oligonucleotides were introduced to cells by electroporation and protein levels were measured by ELISA assay using a murine IL-5 ELISA kit (Endogen, Woburn Mass.). Starting IL-5 concentrations in the absence of oligonucleotide were approximately 2300 pg/ml and this was decreased to approximately 200 pg/ml at 25 .mu.M ISIS 16992 and 400 pg/ml at 25 .mu.M ISIS 16999. An IC50 of approximately 13 .mu.M was obtained for ISIS 16992 and approximately 15 .mu.M for ISIS 16999.
Example 13
Effect of ISIS 16999 on IL-5 Secretion by EL-4 Cells
EL-4 cells were treated with ISIS 16999 at doses from 5 to 20 .mu.M as described in previous examples. Secreted IL-5 in the medium was detected by ELISA assay as in previous examples.
Secreted IL-5 levels were reduced by 13.5-fold as oligonucleotide concentration was increased from zero to 10 .mu.M. ISIS 16989, which did not reduce IL-5 mRNA levels (see Table 2 above), showed much lesser reduction (approximately 2.5-fold) in secreted IL-5 levels. IL-5 levels stayed low for at least 72 hours after treatment with ISIS 16999.

ISIS 17868, 17869, 17860, 18242 and 18243, all gap variants of ISIS 16999 (SEQ ID NO: 26), were tested and compared to the parent oligonucleotide, ISIS 16999 for ability to reduce IL-5 mRNA levels in EL-4 cells. In a screen at 15 .mu.M oligonucleotide concentration (the IC50 for ISIS 16999), ISIS 18243 gave comparable activity to ISIS 16999. ISIS 17870 and 18242 were slightly less active, ISIS 17869 showed modest activity and ISIS 17868 was virtually inactive. In a subsequent dose-response assay, ISIS 17870 and 18243 showed activity comparable to or slightly better than that of ISIS 16999.
ISIS 17858, 17859, 17860, 18246 and 18247, all gap variants of ISIS 16981 (SEQ ID NO: 8), were tested and compared to the parent oligonucleotide, ISIS 16981, for ability to reduce IL-5 mRNA levels in EL-4 cells. In a screen at 15 .mu.M oligonucleotide concentration, ISIS 17859 and 18246 showed activity comparable to the parent, ISIS 16981, with ISIS 18247 only slightly less active. ISIS 17858 and 17860 were more active than the parent compound. All of the ISIS 16981 gap variants tested are therefore preferred.
ISIS 17863, 17864, 17865, 18244 and 18245, all gap variants of ISIS 16992 (SEQ ID NO: 19), were tested and compared to the parent oligonucleotide, ISIS 16992. In a screen at 15 .mu.M oligonucleotide concentration, ISIS 18245 showed activity only slightly (approx 20%) less than the parent compound. ISIS 17863 and 18244 were modestly active and ISIS 17864 and 17865 were nearly inactive. Thus ISIS 18245 is also preferred.
ISIS 16999 was also compared to ISIS 20391, a compound of the same sequence, backbone and gap placement but with 5-methyl cytosines in place of every cytosine (in both the deoxy gap and the 2'-methoxyethoxy regions), and to ISIS 20392, which was identical to ISIS 20391 except the backbone was phosphodiester (P.dbd.O) in the 2' methoxyethoxy regions and phosphorothioate (P.dbd.S) in the deoxy gap. Oligos were compared at doses of 5, 15 and 25 .mu.M for ability to reduce IL-5 mRNA levels in EL-4 cells. Both ISIS 20391 and 20392 showed roughly comparable activity to ISIS 16999, with 20392 slightly more active than the parent. Both of these compounds are therefore preferred. 5-base mismatches of both ISIS 20391 and 20392 were inactive at all concentrations. ISIS 20564, a full phosphodiester compound, was virtually inactive at these concentrations in a separate experiment.

ISIS 20391 reduced IL-5 mRNA levels by 75% compared to ovalbumin-induced IL-5 levels, whereas the mismatch oligonucleotide ISIS 20393 reduced IL-5 mRNA by only 40%.
Example 16
Effect of ISIS 20391 (targeted to murine IL-5) on Ovalbumin-induced Peritonitis in Balb/c Mice.
An eosinophil peroxidase (EPO) colorimetric assay was used to measure the effect of oligonucleotides on eosinophilia in peritoneal lavage fluid after ovalbumin immunization and challenge. The method used is a modification of Strath et al., J. Immunol. Meth., 1985, 83, 209-215. Briefly, the substrate solution consists of 0.05 M o-phenylenediamine dihydrochloride (OPD, Sigma Chem. Co., St. Louis, Mo.) in 0.05 M Tris buffer containing 1 mM hydrogen peroxide and 0.1% Triton X-100. Reaction mixture is added to cells, incubated in the dark for 30 minutes and the reaction was stopped by addition of 1/4 volume of 4 M sulfuric acid. The EPO was measured as the absorbance at 492 nm, blanked against substrate solution. Using this assay, EPO levels are proportional to number of eosinophils present. Mice were dosed chronically with oligonucleotides. Ovalbumin challenge increased EPO levels in peritoneal lavage fluid over sixteenfold. ISIS 20391 dosed chronically at 5 mg/kg reduced EPO levels after ovalbumin induction by 47%. The mismatch control reduced EPO by approximately 12.6%.
A dose-dependent reduction of EPO by ISIS 20391 was obtained, with approximately 75% reduction at 10 mg/kg oligonucleotide dose compared to 29% reduction by the mismatch control. The IL-5 oligonucleotide correspondingly reduced eosinophil infiltration into the peritoneal cavity by 86% compared to the ovalbumin challenge control, while the mismatch only reduced infiltration by 26%. Using chronic subcutaneous administration (5 mg/kg/day for 15 days using implanted minipumps) a slight but reproducible inhibitory effect of the IL-5 oligonucleotide on eosinophilia in an ovalbumin lung challenge model has also been obtained.
Example 17
Reduction of IL-5 Protein in Peritoneal Lavage Fluid by ISIS 20391 Following 7 Day Dosing Schedule
Mice were dosed daily with ISIS 20391 at 5 or 20 mg/kg for 7 days. Following peritoneal lavage, IL-5 protein levels were measured using an ELISA assay. IL-5 levels in ovalbumin-treated mice were approximately 160 pg/ml. Treatment with ISIS 20391 at 5 and 20 mg/kg reduced IL-5 concentrations in peritoneal fluid to 110 and 80 pg/ml, respectively. A control oligonucleotide at 5 and 20 mg/kg reduced IL-5 levels to 160 and 130 pg/ml.
Example 18
Effect of IL-5 Antisense Oligonucleotide on Ovalbumin-induced Murine Lung Asthma Model.
Airway inflammation is observed in patients with allergic asthma. A murine model of allergic asthma has been developed, (Hessel et al. J. Immunol. 1998, 160, 2998-3005). Sensitization of BALB/c mice with ovalbumin induces a high level of ovalbumin-specific IgE in serum. Inhalation of ovalbumin in sensitized mice causes an immediate bronchoconstrictive response. Repeated inhalation of ovalbumin in sensitized animals induces nonspecific airway hyperresponsiveness in vivo, and infiltration of leukocytes in airway tissue.
Pathogen-free male BALB/c ByJ mice were obtained from Jackson Laboratories. Active sensitization is performed by IP injection of 20 ug of ovalbumin (Sigma Chemical Co, St. Louis, Mo., grade II) in aluminum hydroxide adjuvant on days 2 and 9 of 16 days of daily oligonucleotide treatment. This produces high titers of total IgE in mouse serum of which 80% is ovalbumin-specific IgE (Hessel et al., J. Immunol., 1998, 160, 2998-3005). On day 16 of treatment, mice are exposed either 2% ovalbumin aerosol for 1 minute. The aerosol is generated with a nebulizer such as Medix 8001 (Sussex, UK). Oligonucleotides were dissolved in saline and injected daily i.v. in the tail vein by bolus infusion at the indicated doses from 2 days before antigen sensitization through challenge.
Bronchoalveolar lavage (BAL) is used to measure the leukocyte infiltration of airway tissue. 24 hours after the ovalbumin aerosol, mice were euthanized, tracheal cannulation was performed and saline washes collected. Percent eosinophils in BAL were determined.
Unsensitized mice had 1.6% eosinophils in BAL fluid; after ovalbumin sensitization this increased to 37.6%. ISIS 20391 at 5, 10 and 20 mg/kg reduced eosinophilia in BAL to 11.8%, 5.5% and 3.8%, respectively. The latter two are statistically significant reductions. Mismatch control oligonucleotide ISIS 20393 at 10 and 20 mg/kg yielded BAL eosinophil counts of 33.6% and 28.4%, respectively. The positive control, dexamethasone, reduced eosinophil counts to 5.8%.
Airway responsiveness to methacholine is measured in vivo 24 hours after the last aerosol exposure. Baseline nebulized methacholine dose response curves were constructed at day 0 before antigen sensitization for all groups of animals. Pulmonary function was monitored using a Buxco BioSystem Plethysmograph (Buxco, Troy N.Y.) and expressed as enhanced pause (Penh) which correlates to measured airway resistance (Hamelmann et al., Am. J.Respir. Crit. Care Med., 1997, 156, 766-775). Following challenge with aerosolized albumin, pulmonary function recordings were performed for 30 minutes to examine the early phase allergic response. For the late phase reaction, recordings were performed every hour from 2 hours to 9 hours after ovalbumin challenge. Airway responsiveness was measured at 24 hours after antigen challenge by measuring the airway response to methacholine for 3 minutes at each dose. Post-challenge recordings were compared to baseline recordings for each group to generate a Penh stimulation index. As a positive control, dexamethasone was administered i.p., 25 mg/kg, 1 day before the sensitization, 2 hours before the challenge, and 18 hours after the challenge.
Plethysmography results showed that ISIS 20391 at 10 or 20 mg/kg inhibited the methacholine-induced allergic airway hyperresponsiveness, reducing the peak Penh index from approximately 2.0 (no oligo) to approximately 1.25 after oligonucleotide treatment in several experiments. Dexamethasone, the positive control, reduced the Penh to approximately 1.0.
Data from one experiment was expressed another way, in terms of PC100, (provocation challenge.sub.100) the concentration of methacholine needed to give a twofold increase in airway hyperreactivity. Unsensitized mice had a PC100 of 40.1 mg/ml methacholine. After ovalbumin sensitization, the PC100 was 9.84, indicating that much lower doses of methacholine caused the same increase in airway reactivity. This effect was reversible in part by ISIS 20391. At 5 mg/kg ISIS 20391 the PC100 was 10.6, but at 10 and 20 mg/kg the PC100 was increased to 30.7 and 41.6 mg/kg showing a reverse in airway hyperreactivity. Dexamethasone had a PC100 of 29.8 mg/kg methacholine.
Example 19
Early and Late Phase Allergic Airway Response in Mouse Whole Body Plethysmography Model
Ovalbumin challenge produces a two-phased response with separate and distinct peaks in airway hyperreactivity at approximately 2 minutes and approximately 2 hours after ovalbumin challenge. The first peak is about a twofold increase in Penh and the second peak is larger, a three- to four-fold increase in Penh. The late phase response was mitigated by ISIS 20391 at doses of 10 and 20 mg/kg. In particular, the late response, in which Penh reaches approximately 0.7 two hours after ovalbumin challenge (compared to 0.25 for unsensitized mice) was reduced by ISIS 20391 at 10 mg/kg to a Penh of approximately 0.4, which was a statistically significant reduction. Dexamethasone reduced the Penh to approximately 0.3. The mismatch control, ISIS 20393 at 10 mg/kg showed a statistically insignificant reduction of late phase Penh to approximately 0.5. In a higher-dose experiment, ISIS 20391 at 20 mg/kg reduced the Penh 2 hours after ovalbumin challenge from 0.7 to 0.425, which was statistically significant. Mismatch control ISIS 20393 at 20 mg/kg reduced Penh to approximately 0.6 which was not significant, and dexamethasone (positive control) reduced the response to approximately 0.25.

These oligonucleotides were electroporated into human HSB-2 cells and tested for effect on IL-5 mRNA by Northern blot analysis as described in previous examples. The HSB-2 T-cell line was obtained from the American Type Culture Collection and cells are cultured according to ATCC recommendations. They produce IL-5 upon induction with PMA+ionomycin. Oligonucleotides were tested by Northern blot analysis at a concentration of 10 .mu.M for their ability to block IL-5 mRNA expression. The results are shown in Table 5.

ISIS 16084, 16085 and 16094 inhibited IL-5 mRNA expression by at least 40%.
A dose-response curve was generated for inhibition of human IL-5 protein expression in HSB-2 cells by ISIS 16085. Cells untreated with oligonucleotide were found to express approximately 47 pg/ml IL-5. After treatment with ISIS 16085 at 5, 15 and 25 .mu.M doses, IL-5 levels dropped to 21, 0 and 0 pg/ml, respectively. Treatment with a 1-mismatch control oligonucleotide at 5, 15 and 25 .mu.M doses gave IL-5 levels of 26, 25 and 20 pg/ml, respectively. Treatment with a 3-mismatch control oligonucleotide at 5, 15 and 25 .mu.M doses gave IL-5 levels of 52, 48 and 46 pg/ml, respectively. A 5-mismatch oligonucleotide did not inhibit, and at some doses stimulated, IL-5 protein expression.
Example 21
Inhibition of IL-5 Expression by ISIS 16085 in Human CEM T Cells
Using an RNAse protection assay (Riboquant.TM. hCK4, Pharmingen, La Jolla Calif.), it was determined that ISIS 16085 inhibited IL-5 expression in a second T cell line, CEM (obtained from American Type Culture Collection) with an IC50 estimated at approximately 25 .mu.M. IL-5 expression is induced in these cells by treatment with PMA plus ionomycin in the presence of IL-2, anti-CD28 crosslinking antibody, and dibutyryl cAMP. Dose response analysis of ISIS 16085 vs. its 5-mismatch control in stimulated CEM cells showed a dose-dependent decrease in IL-5 mRNA of about 50% at 25 .mu.M oligonucleotide, compared with about 22% reduction with the mismatch control. No decreases were seen in other cytokine gene products measured in this assay panel.

MOUSE IL-5 RECEPTOR
Example 23
Mouse IL-5 Receptor.alpha. Oligos
The mRNA encoding the membrane form of the mouse IL-receptor.alpha. contains 11 exons. The transmembrane domain of the receptor is encoded in exon 9. Two mRNAs encoding soluble (secreted) forms of the receptor result from differential splicing events. The mRNA encoding soluble form 1 of the receptor is missing exon 9 (exon 8 is spliced to exon 10) and the mRNA encoding soluble form 2 is missing exons 9 and 10 (exon 8 is spliced to exon 11). Imamura et al., DNA and Cell Biology, 13, 283-292.
Murine BCL.sub.1 cells were chosen for screening antisense oligonucleotides targeted to murine IL-5 receptor.alpha.. These are B-cell leukemia cells derived from a spontaneously arising tumor of BALB/c origin, and proliferate in response to murine or human IL-5. This is a CD5+ line which resembles a subset of human chronic lymphocytic leukemia tumors and secretes IgM upon lipopolysaccharide stimulation. Cells were obtained from the American Type Culture Collection and cultured in RPMI 1640 medium supplemented with 10% heat-inactivated fetal bovine serum (Sigma Chemical Co., St. Louis, Mo.), 10 mM Hepes, pH 7.2, 50 .mu.M 2-ME, 2 mM L-glutamine, 100 U/ml penicillin and 100 .mu.g/ml streptomycin (Gibco, Grand Island, N.Y.)
A series of antisense oligonucleotides were designed to target the murine IL-5 receptor. All are chimeric "gapmers" with 2'-methoxyethoxy flanks and central 10-base deoxy "gaps" and a phosphorothioate backbone throughout. Cells (1.times.10.sup.7 cells in PBS) were transfected with oligonucleotides by electroporation at 200V, 1000 .mu.F using a BTX Electro Cell Manipulator 600 (Genetronics, San Diego Calif.). Antisense oligonucleotide sequences are shown in Table 8.

In this assay, ISIS 16926, 16927, 16934, 16936, 16945, 16947 and 16949 gave at least approximately 25% inhibition of IL-5R.alpha. mRNA expression and are preferred. Of these, ISIS 16934, 16945 and 16949 gave at least 35% inhibition and are more preferred.
ISIS 16934, 16945 and 16949 were chosen for further study. These demonstrated IC50s for inhibition of murine IL-5 receptor.alpha. mRNA in BCL.sub.1 cells of approximately 2.5 .mu.M, 1.5 .mu.M and 1 .mu.M, respectively. ISIS 16949 was tested for effects on IL-5 receptor.alpha. protein expression and showed nearly complete inhibition.

All of the fully modified 2'-methoxyethoxy oligonucleotides targeted to murine IL-5 receptor.alpha. mRNA exon reduced expression of the membrane form of IL-5 receptor.alpha. and increased expression of the soluble form of the receptor. The potencies of these concurrent effects were coordinately diminished as the antisense target site moved toward the 3' end of the exon. The overall amount of IL-5 receptor.alpha. transcription is unaffected. This demonstrates that fully 2'-methoxyethoxy-modified oligonucleotides targeted to exon 9 just distal to the intronic 3' splice acceptor site blocked inclusion of exon 9 in the splice product and redirect the splicing machinery to the next downstream splice acceptor site (in intron 9). Reduction of the membrane form of IL-5 receptor.alpha., particularly with no decrease or more particularly with an increase in the soluble form, is believed to have therapeutic utility in diseases associated with IL-5 signal transduction, especially asthma. These results show that splicing has been redirected by use of uniformly 2'-methoxyethoxy oligonucleotides targeted to exon 9 to cause exclusion (skipping) of exon 9 from the spliced mRNA products, resulting in controlled alteration of the ratio of soluble/membrane IL-5 receptor produced.
It was also shown that conversion of an RNAse H-dependent compound (the 2' MOE gapmer ISIS 18002) to an RNAse H-independent compound (the fully-2' MOE compound 21752) converted this oligonucleotide sequence from an inhibitor of both forms of IL-5 receptor.alpha. to one which selectively inhibits of the membrane form via splice redirection.
ISIS 21752 was chosen for further study. In dose response experiments, an IC50 of approximately 4 .mu.M was obtained for inhibition of the membrane form of IL-5 receptor.alpha. mRNA. A 1-base mismatch (ISIS 23235) gave an IC50 of approximately 10.5 .mu.M and 3- and 5-base mismatches did not inhibit membrane IL-5 receptor mRNA at any concentration.
Example 26
Oligonucleotides Targeted to Exon-exon Boundaries of Various Forms of Mouse IL-5 Receptor.alpha. mRNA.
Oligonucleotides, either 2' MOE gapmers or uniform 2' MOE, were designed to target exon-exon boundaries of the mature IL-5 receptor.alpha. mRNA. The mRNA encoding the membrane form of the mouse IL-5 receptor.alpha. contains 11 exons. The transmembrane domain of the receptor is encoded in exon 9. Two mRNAs encoding soluble (secreted) forms of the receptor result from differential splicing events. The mRNA encoding soluble form 1 of the receptor is missing exon 9 (exon 8 is spliced to exon 10) and the mRNA encoding soluble form 2 is missing exons 9 and 10 (exon 8 is spliced to exon 11). In Table 14, the target region designated "E7-E8" indicates that the oligonucleotide is targeted to the exon 7-8 boundary, and so forth.

As shown in Table 15, selective reduction of expression of the soluble form of IL-5 receptor.alpha. could be achieved with antisense oligonucleotides targeted to the exon 8-exon 10 boundary, or, to a lesser extent to the exon 8-exon 11 boundary, both of which junctions are only found in the soluble receptor mRNA. Selective reduction of expression of the membrane form of IL-5 receptor.alpha. could be achieved with antisense oligonucleotides targeted to the exon 8-exon 9 boundary or exon 9-exon 10 boundary, both of which are only present in the mRNA targeting the membrane form of IL-5 receptor.alpha.. Placement of the fully-2' MOE oligonucleotides across the intron/exon boundaries of exon 9 resulted in similar effects as were obtained with fully-modified oligonucleotides positioned inside exon 9.
Example 27
Effect of Antisense Oligonucleotides on Expression of Membrane Form of IL-5 receptor.alpha. Protein in Murine BCL.sub.1 Cells
BCL.sub.1 cells were treated with antisense oligonucleotide for 48 hours. Oligonucleotides used were ISIS 16949 ("common" oligonucleotide targeted to both soluble and membrane forms of IL-5 receptor), ISIS 21752, targeted only to the membrane form and ISIS 21853 and 21855, targeted only to the soluble forms of IL-5 receptor.alpha.. Oligonucleotides were introduced by electroporation as described in previous examples. Effect on levels of the membrane form of the receptor was examined by Western blot analysis. Membrane-enriched fractions were prepared as Triton X-100 insoluble material and separated by SDS-PAGE using 8% gels. Antibody to mouse IL-5 receptor.alpha. was purchased from Santa Cruz Biotechnology (Santa Cruz, Calif.) and used at 1:1000 dilution.
Compared to control (no oligonucleotide), ISIS 21752 nearly completely ablated the membrane IL-5 receptor. ISIS 21853 and 21855 together had little to no effect; both target the soluble receptor isoforms specifically. The common sequence oligonucleotide, ISIS 16949, reduced the soluble receptor by 75%.
Transfection with a fully 2'-MOE oligonucleotide targeted to the 5' intron splice site for either exon 8, 9 or 10 resulted in specific exclusion of that particular downstream exon but not others adjacent or upstream. Thus targeting the 5' intron splice sites with high-affinity antisense compounds such as fully 2'-MOE oligonucleotides allows selective deletion of individual exons of the mRNA transcript.
Example 28
Reduction of Eosinophils in Blood and Peritoneal Lavage Fluid of Mice Treated with IL-5 Receptor.alpha. Antisense Oligonucleotide
Mice received daily injections of recombinant mouse IL-5 for 5 days, with or without ISIS 21972 or its mismatch control, ISIS 21969. Percent eosinophils in blood and peritoneal lavage fluid were measured. In control mice (no IL-5, no oligonucleotide) eosinophil levels were 4% in peritoneal lavage fluid and 2% in blood. After IL-5 treatment, eosinophils increased to 13.5% in lavage fluid and 9.5% in blood. Treatment with mismatch oligonucleotide did not change this significantly (13.5% in lavage fluid, 10.5% in blood) but treatment with IL-5 receptor.alpha. antisense oligonucleotide reduced eosinophil levels to 8.5% in peritoneal lavage fluid and 7% in blood.
HUMAN IL-5 RECEPTOR
Example 29
Antisense Oligonucleotides Targeted to Human IL-5 receptor.alpha.
The human IL-5 receptor.alpha. gene contains 14 exons. A membrane-anchored form of the receptor and two soluble forms have been identified. The membrane form is active in signal transduction and the soluble forms can act antagonistically. The mRNA transcript encoding the membrane-anchored form of the human IL-5 receptor.alpha. contain exons 1-10 and 12-14. Exon 11 is spliced out by an alternative splicing event. The major soluble isoform (soluble form 1) is generated as a result of a normal splicing event and an in-frame stop codon in exon 11. The other soluble form (soluble form 2) is generated by the absence of splicing and therefore is generated by reading into intron 11.
mRNA transcripts encoding the membrane form of the human IL-5 receptor.alpha. contain exons 1-10 and 12-14. Exon 11 is spliced out. It is, therefore, possible to target sequences in exons 1-10 which are common to both soluble and membrane forms of the receptor, or to selectively target sequences only present in the membrane form (exons 12-14). A series of antisense oligonucleotides were designed to be specific to only the membrane form of human IL-5 receptor.alpha. (IL-5R.alpha.). These oligonucleotides target regions downstream of exon 11 (i.e., exons 12-14 and intervening introns, stop codon and 3' untranslated region). Tavernier et al., Proc. Natl. Acad. Sci., 1992, 89, 7041-7045.
These are shown in Table 16.

These cells were tested in an IL-5 receptor-expressing subclone of TF-1 cells (provided by Dr. Christoph Walker, Novartis Research Centre, Horsham, UK.

TF-1 cells (1.times.10.sup.7 cells in PBS) were transfected with oligonucleotides by electroporation at 250V, 1000 .mu.F using a BTX ElectroCell Manipulator 600 (Genetronics, San Diego Calif.).
Total cellular RNA was isolated using the RNeasy.TM. kit (Qiagen, Santa Clarita Calif.). Northern blotting was performed using standard methods using a full-length cDNA probe or a cDNA probe corresponding to the membrane isoform-specific exon sequences prepared from HL-60 cell RNA by standard RT-PCR followed by a nested primer reaction.

ISIS 16769, 16773, 16774, 16776, 16777, 16778 and 16779 inhibited the membrane form of IL-5 receptor.alpha. by at least 40% and are preferred. Of these, ISIS 16769, 16774, 16778 and 16779 are more preferred because of their minimal effect on the soluble form of IL-5R.alpha..
The effect of ISIS 16778 on expression of human IL-5 receptor.alpha. protein on the surface of TF-1 cells was measured by flow cytometry. Following electroporation with oligonucleotide, TF-1 cells were incubated for 24 hours or as indicated, collected by centrifugation and washed with cold PBS. Cells were transferred to 12.times.75 mm polystyrene tubes and washed in 2% bovine serum albumin, 0.2% sodium azide in PBS at 4.degree. C. Cells were centrifuged at 200.times.g and the supernatant was decanted. Specific antibody was then added at 1:100 for human IL-5 receptor.alpha.-phycoerythrin and the isotype control antibody in 0.1 mL of the above buffer. Antibodies were incubated with the cells for 30 minutes at 4.degree. C. in the dark with gentle agitation. Cells were then washed as above and resuspended in 0.3 mL of FacsFlow buffer (Becton Dickinson, Franklin Lakes, N.J.) with 0.5% formaldehyde. Cells were analyzed on a Becton-Dickinson FACScan. Results are expressed as the percentage of control expression based on mean fluorescence intensity, subtracting basal expression.
In dose-response experiments to determine the effect of this oligonucleotide on human IL-5 receptor.alpha. cell surface protein expression in TF-1 cells, ISIS 16778 demonstrated an IC50 of approximately 5 .mu.M. A 1-mismatch control had an IC50 of 7.5 .mu.M and 3- and 5-mismatch controls did not inhibit IL-5 receptor.alpha. below 75% of control.
An additional set of oligonucleotides was designed to target both membrane and soluble forms of human IL-5 receptor. These oligonucleotides, targeted to exons 1-10 and intervening introns, are sometimes referred to as "common" IL-5 receptor oligonucleotides. Sequences are shown in Table 18.

Of these, ISIS 16786, 16788, 16789, 16790 and 16793 inhibited both isoforms by greater than 75%.
ISIS 16793 was chosen for further study. It totally inhibited expression of both soluble and membrane forms of human IL-5 receptor.alpha. mRNA. This compound was found to have an IC50 of approximately 2 .mu.M for reduction of IL-5 receptor.alpha. cell surface protein in TF-1 cells. A 1-mismatch control had an IC50 of approximately 3 .mu.M and 3- and 5-mismatch controls did not inhibit IL-5 receptor.alpha. expression below 75% of control.

Antisense Oligonucleotides Targeted to Splice Sites in the Human IL-5 Receptor.alpha. mRNA
The human IL-5 receptor.alpha. gene contains 14 exons. A membrane-anchored form of the receptor and two soluble forms have been identified. As with the mouse receptor, the membrane form is active in signal transduction and the soluble forms are not, and can act antagonistically. The mRNA transcript encoding the membrane-anchored form of the human IL-5 receptor.alpha. contain exons 1-10 and 12-14. Exon 11 is spliced out by an alternative splicing event. The major soluble isoform (soluble form 1) is generated as a result of a normal splicing event and an in-frame stop codon in exon 11. The other soluble form (soluble form 2) is generated by the absence of splicing and therefore is generated by reading into intron 11.
Transcripts encoding soluble forms of human IL-5 receptor.alpha. do not contain exons 12, 13 or 14. It is, therefore, possible to target sequences in exons 1-10 which are common to both soluble and membrane forms of the receptor, or to selectively target sequences only present in the membrane form (exons 12-14). Oligonucleotides were also designed to target various intron/exon boundaries downstream of exon 11, with the intention of preventing successful splicing downstream of exon 11 and thus redirecting splice products away from the membrane form and in favor of the soluble form of IL-5 receptor.alpha.. A series of oligonucleotides were designed to target various splice sites or (intron-exon boundaries) in the IL-5 receptor mRNA. These are shown in Table 20 and their effect on IL-5 receptor mRNA and cell surface protein levels is shown in Tables 21 and 22.

ISIs 16746, 16748 and 16755 inhibited IL-5 membrane receptor mRNA expression by over 50% and are therefore preferred in this assay. Northern blot analysis indicated that ISIS 16755 inhibited the membrane receptor transcript without significantly inhibiting the soluble form. Thus it is believed that ISIS 16755 redirects splicing in favor of the membrane form, as is consistent with data obtained with other non-RNAse H (e.g., uniform 2'-methoxyethoxy) oligonucleotides targeted to splice sites.

ISIS 16746, 16748, 16755 and 16758 inhibited human IL-5 receptor.alpha. protein by over 50% in this assay and are therefore preferred. ISIS 16758 and 16755 were chosen for further study. ISIS 16758 was found to have an IC50 of approximately 5 .mu.M for reduction of IL-5 receptor.alpha. cell surface protein in TF-1 cells. A 1-mismatch control had an IC50 of 10 .mu.M and 3- and 5-mismatch controls did not inhibit IL-5 receptor.alpha. expression. ISIS 16758 inhibited IL-5 receptor.alpha. protein expression without reducing mRNA levels, consistent with an RNAse H-independent mechanism as predicted for a uniformly 2'-methoxyethoxy modified oligonucleotide.

Induction of Apoptosis in TF-1 Cells Treated with IL-5 Receptor.alpha. Oligonucleotide
1.times.10.sup.6 TF-1 cells cultured in IL-5 (0.5 ng/ml) were collected 48 hours following oligonucleotide treatment (transfection was by electroporation as described in previous examples) and phosphatidylserine expression was detected as a measure of apoptosis using the Annexin-V flow cytometry kit (Clontech, Palo Alto, Calif.) according to the manufacturer's instructions. Briefly, cells were resuspended in 0.2 ml of staining buffer (10 mM Hepes, pH 7.4, 140 mM NaCl, 5 mM CaCl.sub.2) and 10 .mu.M of propidium iodide (50 .mu.g/ml) and 5 .mu.l of Annexin V reagent were added at 4.degree. C. for 10 minutes. The samples were diluted with FacsFlow (Becton Dickinson, Franklin Lakes N.J.) buffer and analyzed on a Becton Dickinson FACScan. Results are shown in Table 23.

Effect of IL-5 Receptor Oligonucleotides on Cell Proliferation
2.5.times.10.sup.4 TF-1 cells were incubated in 96-well plates in 200 .mu.l complete RPMI in the absence of IL-5 for 16 hours following electroporation. IL-5 (0.5 ng/ml) was added and the cultures were pulsed with 1 .mu.Ci of [.sup.3 H]-thymidine for the last 8 hours of a 48-hour culture period. The cells were harvested on glass fiber filters and analyzed for thymidine incorporation (proportional to cell proliferation) by liquid scintillation counting.
Results are shown in Table 24. Results are compared to thymidine incorporation in untreated controls.

These data demonstrate that antisense inhibitors of IL-5 receptor.alpha. greatly reduce cellular response to IL-5, i.e., cell proliferation in response to IL-5. Control oligonucleotides were ineffective.
