The present disclosure relates to methods of treating ocular neovascular disease and disorders in an individual that comprise administering a single unit dose of a recombinant adeno associated virus (rAAV) particles encoding an anti-VEGF agent (e.g., aflibercept) to an eye of an individual.
Age-related macular degeneration (AMD) is a degenerative ocular disease affecting the macula, a light sensitive, small area in the center of the retina that is responsible for reading and fine vision. Conditions affecting the macula reduce central vision while leaving peripheral vision intact. In severe cases, the disease can lead to central blindness. AMD is a notable cause of vision loss in the US population among persons 65 years and older, and the estimated prevalence of any AMD among persons over 40 years of age is approximately 6.5% (Klein et al., (2011) Arch Ophthalmol, 129 (1): 75-80). Neovascular or exudative or wet AMD (nAMD, wAMD, or nwAMD) is an advanced form of AMD. The hallmark of wAMD is choroidal neovascularization (CNV), which is the infiltration of abnormal blood vessels in the retina from the underlying choroid layer, resulting in retinal cell damage and central blindness. This abnormal angiogenic process is modulated by growth factors, in particular, vascular endothelial growth factor (VEGF). The standard of care of wAMD is a class of molecules that bind to and sequester VEGF, such as ranibizumab (Lucentis) and aflibercept (Eylea).
Diabetic retinopathy (DR) is a major complication of diabetes mellitus and is a leading cause of visual loss in the working age population. DR may be non-proliferative (NPDR), with no new blood vessel growth, or proliferative DR (PDR), with new abnormal blood vessel growth within the retina or choroid. Diabetic macular edema (DME) is a complication of DR and is another example of an ocular disease affecting the macula. DME affects up to 10% of people with diabetes and is caused by fluid accumulation in the macula. DME is the most frequent cause of sight loss in people with DR. Available therapies for treating DME include laser and anti-vascular endothelial growth factor (anti-VEGF) drugs such as aflibercept.
Aflibercept is a recombinant fusion protein that acts as a decoy receptor for vascular endothelial growth factor subtypes A and B (VEGF-A and VEGF-B) and placental growth factor (PGF). By binding to these ligands, aflibercept is able to prevent them from binding to vascular endothelial growth factor receptors (VEGFR), VEGFR-1 and VEGFR-2, to suppress neovascularization and decrease vascular permeability. Aflibercept consists of domain 2 of VEGFR-1 and domain 3 of VEGFR-2 fused with the Fc fragment of IgG1.
Current standard of care anti-VEGF agents such as aflibercept need to be re-administered via intravitreal (IVT) injection every 4 to 8 weeks to achieve optimal therapeutic outcomes and maintain visual acuity. Compliance with such a regimen is burdensome to patients, their caregivers, and the healthcare system, and most patients fall out of compliance with the optimal regimen over time, which is correlated with vision loss (Khanani A M, et al.). In addition, there are complications including endophthalmitis, retinal detachments, traumatic cataract, and elevated intraocular pressure (IOP); the risks of these complications are likely to increase with repeated IVT injections (Falavarjani et al., (2013) Eye (Lond), 27 (7): 787-794).
Therefore, there is a need in the art for therapies for ocular neovascular diseases such as wAMD, DR, or DME that are effective, reduce the risk of adverse effects, and are amenable to high long-term patient compliance.

In some embodiments, a variant can have at least about 90% overall sequence homology to the wild-type protein. In some embodiments, a variant exhibits at least about 95%, at least about 98%, at least about 99%, at least about 99.5%, or at least about 99.9% overall sequence identity.
As used herein, “recombinant” can refer to a biomolecule, e.g., a gene or protein, that (1) has been removed from its naturally occurring environment, (2) is not associated with all or a portion of a polynucleotide in which the gene is found in nature, (3) is operatively linked to a polynucleotide which it is not linked to in nature, or (4) does not occur in nature. The term “recombinant” can be used in reference to cloned DNA isolates, chemically synthesized polynucleotide analogs, or polynucleotide analogs that are biologically synthesized by heterologous systems, as well as proteins and/or mRNAs encoded by such nucleic acids. Thus, for example, a protein synthesized by a microorganism is recombinant, for example, if it is synthesized from an mRNA synthesized from a recombinant gene present in the cell.
The term “anti-VEGF agent” includes any therapeutic agent, including proteins, polypeptides, peptides, fusion protein, multimeric proteins, gene products, antibody, human monoclonal antibody, antibody fragment, aptamer, small molecule, kinase inhibitor, receptor or receptor fragment, or nucleic acid molecule, that can reduce, interfere with, disrupt, block and/or inhibit the activity or function of an endogenous VEGF and/or an endogenous VEGF receptor (VEGFR), or the VEGF-VEGFR interaction or pathway in vivo. An anti-VEGF agent can be any one of the known therapeutic agents that can reduce new blood vessel growth or formation and/or oedem, or swelling, when delivered into a cell, tissue, or a subject in vivo, e.g., ranibizumab, brolucizumab, or bevacizumab. In some embodiments, an anti-VEGF agent can be naturally occurring, non-naturally occurring, or synthetic. In some embodiments, an anti-VEGF agent can be derived from a naturally occurring molecule that was subsequently modified or mutated to confer an anti-VEGF activity. In some embodiments, an anti-VEGF agent is a fusion or chimeric protein. In such proteins, functional domains or polypeptides are artificially fused to a moiety or a polypeptide to make a fusion or chimeric protein that can sequester VEGF in vivo or function as a VEGFR decoy. In some embodiments, an anti-VEGF agent is a fusion or chimeric protein that blocks endogenous VEGFR from interacting with its ligands.
As used herein, “VEGF” can refer to any isoform of VEGF, unless required otherwise, including, but not limited to, VEGF-A, VEGF-B, VEGF-C, VEGF-D, VEGF-E, VEGF-F, or any combination, or any functional fragment or variant thereof. Unless required otherwise, “VEGF” can refer to any member of the VEGF family, including members: VEGF-A, placenta growth factor (PGF), VEGF-B, VEGF-C, and VEGF-D, or any combination, functional fragment, or variant thereof. As used herein, “VEGF receptor” or “VEGFR” or “VEGF-R” can be used to refer to any one of the receptors of VEGF, including, but not limited to, VEGFR-1 (or Flt-1), VEGFR-2 (or Flk-1/KDR), and VEGFR-3 (or Flt-4). VEGFR can be a membrane bound or soluble form, or a functional fragment or truncation of a receptor. Examples of anti-VEGF agents include, but are not limited to, ranibizumab, bevacizumab, brolucizumab, or any combination, variant, or functional fragment thereof.
“Operatively linked” or “operably linked” or “coupled” can refer to a juxtaposition of genetic elements, wherein the elements are in a relationship permitting them to operate in an expected manner. For instance, a promoter can be operatively linked to a coding region if the promoter helps initiate transcription of the coding sequence. There may be intervening residues between the promoter and coding region so long as this functional relationship is maintained.
The term “expression vector” or “expression construct” or “cassette” or “plasmid” or simply “vector” can include any type of genetic construct, including AAV or rAAV vectors, containing a nucleic acid or polynucleotide coding for a gene product in which part or all of the nucleic acid encoding sequence is capable of being transcribed and is adapted for gene therapy. The transcript can be translated into a protein. In some embodiments, the transcript is partially translated or not translated. In certain aspects, expression includes both transcription of a gene and translation of mRNA into a gene product. In other aspects, expression only includes transcription of the nucleic acid encoding genes of interest. An expression vector can also comprise control elements operatively linked to the encoding region to facilitate expression of the protein in target cells. The combination of control elements and a gene or genes to which they are operably linked for expression can sometimes be referred to as an “expression cassette,” a large number of which are known and available in the art or can be readily constructed from components that are available in the art.
The term “heterologous” can refer to an entity that is genotypically distinct from that of the rest of the entity to which it is being compared. For example, a polynucleotide introduced by genetic engineering techniques into a plasmid or vector derived from a different species can be a heterologous polynucleotide. A promoter removed from its native coding sequence and operatively linked to a coding sequence with which it is not naturally found linked can be a heterologous promoter.
As used herein, “7m8” refers to the amino acid sequence LALGETTRPA (SEQ ID NO: 1).

Current therapies (e.g., aflibercept recombinant protein, ranibizumab recombinant protein) for ocular neovascular diseases such as wAMD require lifelong IVT administration approximately every 4-8 weeks. This can increase the risk of inflammation, infection, and other adverse effects in some patients. Further, current therapies create compliance challenges due to repeated and/or frequent trips to medical offices for administration of the therapy, especially in elderly patients, who are most affected with wAMD. Reduction in frequency of administration is associated with vision loss and deterioration of the eye disease or condition. The ability of AAV vectors to efficiently transduce target retinal cells following IVT injection has been exploited to successfully transfer therapeutic genes into photoreceptors, retinal pigment epithelium, and the inner retina to treat a variety of retinal diseases. Thus, administration of rAAV particles encoding an anti-VEGF agent (e.g., aflibercept) can provide prolonged and/or sustained release of the anti-VEGF agent in vivo.
Surprisingly, administration of a single low unit dose of 6×1011 vector genomes (vg) per eye of rAAV particles encoding aflibercept to the eyes of individuals with an ocular neovascular disease led to stabilization of the disease and a robust anatomical response in all treated individuals (See Example 1). In addition, visual acuity was stabilized in all treated individuals and none of the individuals required rescue anti-VEGF treatment (e.g., aflibercept IVT injections) after administration of the single low unit dose of 6×1011 vg/eye of rAAV particles encoding aflibercept. Moreover, administration of the single unit dose of rAAV particles encoding aflibercept to the eyes of individuals with an ocular neovascular disease unexpectedly caused a reduction (e.g., resolution) of symptoms, including intraretinal and subretinal fluid that were refractory to prior anti-VEGF treatments (e.g., chronic IVT injections of aflibercept, ranibizumab, or bevacizumab).
Accordingly, the present disclosure provides methods of treating an ocular neovascular disease in an individual by administering a single unit dose of 6×1011 vg/eye or less of rAAV particles encoding an anti-VEGF agent (e.g., aflibercept). In addition, the present disclosure provides methods for reducing retinal fluid in the eye of an individual with an ocular neovascular disease by administering a single unit dose of rAAV particles encoding an anti-VEGF agent (e.g., aflibercept). The methods disclosed herein reduce or eliminate the need for repeated IVT injections while providing long-term efficacy, thereby addressing the non-compliance and non-adherence problem. In addition, the methods provided herein reduce the adverse effects associated with multiple IVT injections.
Provided herein is a method for treating an ocular neovascular disease in an individual, the method comprising administering a unit dose of recombinant adeno-associated virus (rAAV) particles to an eye of the individual.
Also provided herein is a method for reducing retinal fluid in the eye of an individual with an ocular neovascular disease, the method comprising administering a unit dose of rAAV particles to an eye of the individual.

In some embodiments, the maintenance or the improvement of visual acuity (e.g., BCVA) compared to the visual acuity prior to administration of the unit dose of rAAV particles is present at any of about 1 day, about 1 week, about 2 weeks, about 4 weeks, about 8 weeks, about 12 weeks, about 16 weeks, about 20 weeks, about 24 weeks, about 28 weeks, about 32 weeks, about 36 weeks, about 40 weeks, about 44 weeks, about 48 weeks, about 52 weeks, about 56 weeks, about 60 weeks, about 64 weeks, about 68 weeks, about 72 weeks, about 76 weeks, about 80 weeks, about 84 weeks, about 88 weeks, about 92 weeks, about 96 weeks, about 100 weeks, about 104 weeks, about 108 weeks, or more, after administration of the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual. In some embodiments, the maintenance or the improvement of visual acuity (e.g., BCVA) compared to the visual acuity prior to administration of the unit dose of rAAV particles is present at about 30 weeks or more after administration of the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual. In some embodiments, the maintenance or the improvement of visual acuity (e.g., BCVA) compared to the visual acuity prior to administration of the unit dose of rAAV particles is present at any of about 30 weeks, about 34 weeks, about 44 weeks, about 6 months, about 1 year, about 1.5 years, about 2 years, about 3 years, about 5 years, about 10 years, or more, after administration of the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is assessed based on best corrected visual acuity (BCVA) in the one eye and/or the contralateral eye. In some embodiments, BCVA is expressed as an ETDRS score, which corresponds to the number of letters correctly read (Vitale et al., (2016) JAMA Opthalmol 134 (9): 1041:1047). In some embodiments, an individual is determined to have maintenance of vision and/or visual acuity if the individual loses fewer than 15 letters in an ETDRS score (e.g., any of 15 or less, 14 or less, 13 or less, 12 or less, 11 or less, 10 or less, 9 or less, 8 or less, 7 or less, 6 or less, 5 or less, 4 or less, 3 or less, 2 or less, 1, or 0 letters) compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, an individual is determined to have an improvement of vision and/or visual acuity if the individual gains at least 15 letters (e.g., any of at least about 15, at least about 20, at least about 30, at least about 40, at least about 50, at least about 60, or about 70 letters) comparted to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is assessed based on central subfield thickness (CST) or central retinal thickness (CRT) in the one eye and/or the contralateral eye. In some embodiments, CST or CRT is determined by SD-OCT. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the CST or CRT assessed by SD-OCT is decreased after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the CST or CRT assessed by SD-OCT is maintained after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is assessed based on macular volume in the one eye and/or the contralateral eye. In some embodiments, macular volume is determined by SD-OCT. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the macular volume assessed by SD-OCT is decreased after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the macular volume assessed by SD-OCT is maintained after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is assessed based on retinal thickness (e.g., central retinal thickness (CRT) or central subfield thickness (CST)) and macular volume in the one eye and/or the contralateral eye. In some embodiments, CST and macular volume are determined by SD-OCT. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the CST and macular volume assessed by SD-OCT are decreased after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if the CST and macular volume assessed by SD-OCT are maintained after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye compared to prior to administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is assessed based on the number of rescue therapy treatments (e.g., aflibercept injections) required by the individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if an individual requires less than one rescue therapy treatment (e.g., aflibercept injection) any of every 4 weeks, every 5 weeks, every 6 weeks, every 7 weeks, every 8 weeks, every 9 weeks, every 10 weeks, or more, after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.
In some embodiments, treatment of an ocular neovascular disease in an individual after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye is determined if an individual does not require any rescue therapy treatment (e.g., aflibercept injection) for any of at least 1 week, at least 2 weeks, at least 3 weeks, at least 4 weeks, at least 5 weeks, at least 6 weeks, at least 7 weeks, at least 8 weeks, at least 9 weeks, at least 10 weeks, at least 15 weeks, at least 20 weeks, at least 30 weeks, at least 40 weeks, at least 50 weeks, at least 60 weeks, at least 70 weeks, at least 80 weeks, at least 90 weeks, at least 100 weeks, at least 110 weeks, or more, after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.

In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 12 months after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 10 months after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 7 months after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 6 months after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 2 months after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye. In some embodiments, the individual does not require any rescue therapy treatment (e.g., aflibercept injection) for at least about 1 month after administration of the unit dose of rAAV particles in the one eye and/or the contralateral eye.

In some embodiments, the recombinant adeno-associated virus (rAAV) particles comprise a recombinant viral vector derived from adeno-associated virus (AAV) that has been altered so that it is replication-defective in the subject (e.g., a human or a non-human primate). In some embodiments, the adeno-associated virus (AAV) is a recombinant AAV (rAAV).
AAV or rAAV are small non-enveloped single-stranded DNA viruses. rAAVs are non-pathogenic human parvoviruses and can be made to be dependent on helper viruses, including adenovirus, herpes simplex virus, vaccinia virus and CMV, for replication.
Exposure to wild type (wt) AAV is not associated or known to cause any human pathologies and is common in the general population, making AAV or rAAV a suitable delivery system for gene therapy. AAV and rAAV used for gene therapy for delivery of an anti-VEGF agent, e.g., aflibercept, can be of any serotype. In some embodiments, the methods of the disclosure provide for use of any suitable AAV serotype, including AAV1, AAV2, AAV2.5, AAV3, AAV4, AAV5, AAV6, AAV7, AAV8, AAV9, AAV10, AAV11, AAV12, rh10, AAV-DJ, and any hybrid or chimeric AAV thereof. In some embodiments, the serotype used is based on tropism of the virus, or infectivity of a target cell of interest. In some embodiments, several AAV vectors may be generated to allow selection of the most optimal serotype for use with an anti-VEGF agent transgene (e.g., aflibercept transgene).
In some embodiments, the methods of the present disclosure provide for the use of pseudotyped AAV. Pseudotyped AAV particles comprise AAV genome inverted terminal repeats (ITRs) of one AAV serotype enbcapsidated by an AAV capsid of another AAV serotype. Typically, pseudotyped AAV is designated as “AAV #/#”, where the first “#” indicates the AAV ITR serotype and the second “#” indicates capsid serotype. For example, an AAV particle comprising AAV2 ITRs and an AAV1 capsid would be designated “AAV2/1”.
In some embodiments, the rAAV particles comprise a nucleic acid, e.g., a heterologous nucleic acid. In some embodiments, the nucleic acid encodes a transgene, e.g., an anti-VEGF agent (e.g., aflibercept). In some embodiments, the encoded transgene, e.g., anti-VEGF agent, is under the transcriptional control of a promoter that initiates transcription of the nucleic acid. In some embodiments, the promoter is a “ubiquitous” promoter. In some embodiments, the promoter is a “strong” or constitutively active promoter, e.g., a cytomegalovirus (CMV) promoter, an elongation factor 1 alpha (EFla) promoter, a glyceraldehyde 3-phosphate dehydrogenase (GAPDH) promoter, or a connexin36 (or “Cx36”) promoter. In some embodiments, the promoter is a tissue-specific promoter that is activated in specific tissues or cells, such as retinal cells, to reduce potential toxicity or undesirable effects to non-targeted cells. In some aspects, several AAV vectors may be generated to allow selection of the most optimal serotype and promoter for use with the anti-VEGF agent transgene (e.g., aflibercept transgene). In some embodiments, the nucleic acid is flanked by AAV inverted terminal repeats (ITRs). In some embodiments, the nucleic acid is flanked by AAV2 ITRs.
In some embodiments, the AAV vector comprises a polynucleotide cassette for enhanced expression of a transgene (e.g., an anti-VEGF agent such as aflibercept) in a target cell (e.g., a retinal cell). In some embodiments, the polynucleotide cassette comprises in 5′ to 3′ order: (a) a first enhancer region comprising a CMV sequence (SEQ ID NO: 22); (b) a promoter region, comprising a CMV sequence (SEQ ID NO: 23); (c) a 5′UTR region comprising, in 5′ to 3′ order, TPL and eMLP sequences (SEQ ID NO: 24 and SEQ ID NO: 25, respectively); (d) a coding sequence encoding a peptide or polypeptide (e.g., an anti-VEGF agent such as aflibercept); (e) a second enhancer region comprising a full EES sequence (SEQ ID NO: 26); and (f) a HGH polyadenylation site (SEQ ID NO: 27). In certain of these embodiments, the polynucleotide cassette comprises one or more sequences selected from SEQ ID NOs: 28-32, or a sequence with at least 85% identity thereto. In certain of these embodiments, the 5′ arm of the polynucleotide cassette comprises or consists of SEQ ID NO: 33 or a sequence with at least 85% identity thereto. In certain of these embodiments, the 3′ arm of the polynucleotide cassette comprises or consists of SEQ ID NO: 34 or a sequence with at least 85% identity thereto. The nucleic acid sequences of SEQ ID NOs: 22-34 are provided below:
In some embodiments, the polynucleotide cassette comprises or consists of SEQ ID NO: 39 or a sequence with at least 85% identity thereto.
SEQ ID NO: 39 shown above comprises, in the 5′ to 3′ direction, an inverted terminal repeat (ITR) of AAV serotype 2 comprising nucleotides 1-145 of SEQ ID NO: 39; a CMV promoter comprising nucleotides 180-693 of SEQ ID NO: 39; a 5′ Untranslated Region (UTR), including an Adenovirus Tripartite Leader Sequence and Synthetic Intron, and comprising nucleotides 694-1314 of SEQ ID NO: 39; a Kozak sequence comprising nucleotides 1329-1340 of SEQ ID NO: 39; a codon-optimized aflibercept cDNA sequence comprising nucleotides 1338-2714 of SEQ ID NO: 39; a 3′ UTR including a human scaffold attachment region and comprising nucleotides 2717-3527 of SEQ ID NO: 39; a human growth hormone polyadenylation/transcription stop signal comprising nucleotides 3546-3748 of SEQ ID NO: 39; and an inverted terminal repeat (ITR) of AAV serotype 2 comprising nucleotides 3772-3916 of SEQ ID NO: 39.

In some embodiments, the nucleic acid sequence of aflibercept is modified or codon-optimized to enhance its activity, expression, stability, and/or solubility in vivo.
Aflibercept is a 115 kDa fusion protein, which can be glycosylated. Aflibercept comprises an IgG backbone fused to extracellular VEGF receptor sequences of the human VEGFR-1 and VEGFR-2, and functions like a soluble decoy receptor by binding VEGF-A with a greater affinity than its natural or endogenous receptors. See, for example, Stewart M W. Aflibercept (VEGF Trap-eye): the newest anti-VEGF drug. Br. J. Ophthalmol. 2012 September; 96 (9): 1157-8. Aflibercept's high affinity for VEGF interferes or disrupts subsequent binding and activation of native or endogenous VEGF receptors. Reduced VEGF activity can lead to decreased angiogenesis and vascular permeability. Inhibition of placental growth factor PIGF and VEGF-B by aflibercept may also contribute to the treatment of ocular diseases or disorders characterized by abnormal (e.g., excessive) angiogenesis and/or neovascularization. PIGF has been associated with angiogenesis and certain ocular diseases or disorders, such as wet AMD, may be associated with elevated levels of PIGF. VEGF-B overexpression can be associated with breakdown of the blood-retinal barrier and retinal angiogenesis. Thus, inhibition of VEGF-A, VEGF-B, and PIGF may all contribute to the efficacy of aflibercept.

Minimizing the volume of the unit dose to be administered to the subject may obviate or mitigate changes in ocular pressure and other adverse effects associated with IVT injection (e.g., elevated intraocular pressure, inflammation, irritation, or pain).
Pharmaceutical formulations suitable for ocular use include sterile aqueous solutions or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions, suspension, or dispersion. For intravitreal administration, suitable carriers include physiological saline, bacteriostatic water, phosphate buffered saline (PBS), and/or an isotonic agent, e.g., glycerol. In certain embodiments, the pharmaceutical formulation is sterile and fluid to the extent that easy syringability or injectability exists. In certain embodiments, the pharmaceutical formulation is stable under the conditions of manufacture and storage and is preserved against the contaminating action of microorganisms such as bacteria and fungi. In some embodiments, the pharmaceutical composition can include an isotonic agent, such as a salt or glycerol. In some embodiments, a surfactant or a stabilizer is added to the pharmaceutical composition to prevent aggregation.
In some embodiments, the pharmaceutical formulation contains an excipient or a carrier. A carrier is a solvent or dispersion medium containing, for example, water, saline, ethanol, a polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol, and the like), and any combination thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants such as polysorbates (e.g., Tween™, polysorbate 20, polysorbate 80), sodium dodecyl sulfate (sodium lauryl sulfate), lauryl dimethyl amine oxide, cetyltrimethylammonium bromide (CTAB), polyethoxylated alcohols, polyoxyethylene sorbitan, octoxynol (Triton X100™), N, N-dimethyldodecylamine-N-oxide, hexadecyltrimethylammonium bromide (HTAB), polyoxyl 10 lauryl ether, Brij 721™, bile salts (sodium deoxycholate, sodium cholate), pluronic acids (F-68, F-127), polyoxyl castor oil (Cremophor™) nonylphenol ethoxylate (Tergitol™), cyclodextrins, and ethylbenzethonium chloride (Hyamine™). Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, cresol, thimerosal, and the like. In many embodiments, isotonic agents are included in the pharmaceutical formulation, for example, sugars, polyalcohols such as mannitol, sorbitol, and/or sodium chloride. Prolonged absorption of the internal compositions can be brought about by including in the composition an agent that delays absorption, for example, aluminum monostearate and gelatin. In some embodiments, the pharmaceutical carrier includes sodium phosphate, sodium chloride, polysorbate, and sucrose. In some embodiments, a pharmaceutical formulation comprises a surfactant, e.g., non-ionic surfactant such as polysorbate, poloxamer, or pluronic. In some embodiments, the addition of a non-ionic surfactant reduces aggregation in the pharmaceutical composition.

In some embodiments, the individual has not received a prior aflibercept treatment in the one eye and/or the contralateral eye.
In some embodiments, the ocular disease or disorder treated according to the methods described herein is diabetic macular edema. Diabetic macular edema (DME) is a swelling of the retina in diabetes mellitus due to leaking of fluid from blood vessels within the macula. The macula is the central portion of the retina, a small area rich in cones, the specialized nerve endings that detect color and upon which daytime vision depends. As macular edema develops, blurring occurs in the middle or just to the side of the central visual field. Visual loss from diabetic macular edema can progress over a period of months and make it impossible to focus clearly. Common symptoms of DME are blurry vision, floaters, double vision, and eventually blindness if it goes untreated. In some embodiments, methods and pharmaceutical compositions as disclosed herein are used to treat DME. In some embodiments, treatment of DME is assessed by measuring refraction or visual acuity (e.g., BCVA using ETDRS letters). In some embodiments, visual acuity is measured starting at a distance of about 4 meters prior to dilation of the one eye and/or the contralateral eye. In some embodiments, visual acuity is considered to be maintained if the individual loses fewer than 15 letters in the ETDRS score after administration of the unit dose of rAAV particles compared to prior to administration of the unit dose of rAAV particles. In some embodiments, treatment of DME is assessed by SD-OCT and/or OCT-A. In some embodiments, treatment of DME is assessed by measuring central subfield thickness and/or macular volume using SD-OCT. In some embodiments, treatment of DME is assessed by the number of treatments with an anti-VEGF agent (e.g., aflibercept) administered after administration of the unit dose of rAAV particles (e.g., aflibercept rescue treatments). In some embodiments, one or more aflibercept rescue treatments are administered after administration of the unit dose of rAAV particles if an increase in central subfield thickness (CST) of >50 μm occurs, assessed by SD-OCT, compared to the lower of the two CST measurements recorded prior to administration of the unit dose of rAAV particles (e.g., on Day 1) and about 3 weeks after administration of the unit dose of rAAV particles (e.g., on Week 4). In some embodiments, one or more aflibercept rescue treatments are administered after administration of the unit dose of rAAV particles if loss of >5 letters in BCVA occurs due to worsening DME disease activity compared to the higher of the two BCVA measurements recorded prior to administration of the unit dose of rAAV particles (e.g., on Day 1) and about 3 weeks after administration of the unit dose of rAAV particles (e.g., on Week 4). In some embodiments, treatment of DME is assessed using the Diabetic Retinopathy Severity Scale (DRSS), e.g., using ultra-wide field color fundus photography, compared to DRSS prior to administration of the unit dose of rAAV particles. In some embodiments, treatment of DME is assessed by the occurrence of vision threatening complications (e.g., anterior segment neovascularization, diabetic macular edema, high-risk PDR development, vitreous hemorrhage, or tractional retinal detachment). In some embodiments, vision threatening complications are assessed by ultra-wide field imaging and clinical examination. In some embodiments, the administering the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual results in a 2-step or in a 3-step improvement in Diabetic Retinopathy Severity Scale (DRSS). In some embodiments, the administering the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual results in a 2-step improvement in Diabetic Retinopathy Severity Scale (DRSS). In some embodiments, the administering the unit dose of rAAV particles to the one eye and/or to the contralateral eye of the individual results in a 3-step improvement in Diabetic Retinopathy Severity Scale (DRSS).
In some embodiments, the ocular disease or disorder treated according to the methods described herein is a retinal vein occlusion. Retinal vein occlusion is a blockage of the small veins that carry blood away from the retina. The retina is the layer of tissue at the back of the inner eye that converts light images to nerve signals and sends them to the brain. Retinal vein occlusion is most often caused by hardening of the arteries (atherosclerosis) and the formation of a blood clot. Blockage of smaller veins (branch veins or BRVO) in the retina often occurs in places where retinal arteries that have been thickened or hardened by atherosclerosis cross over and place pressure on a retinal vein. Symptoms of retinal vein occlusion can include a sudden blurring or vision loss in all or part of one eye.
In some embodiments, the ocular disease or disorder treated according to the methods described herein is choroidal neovascularization (CNV), also known as wet age-related macular degeneration (wAMD). Choroidal neovascularization can involve the growth of new blood vessels that originate from the choroid through a break in the Bruch membrane into the sub-retinal pigment epithelium (sub-RPE) or subretinal space, which can be a major cause of visual loss. CNV can create a sudden deterioration of central vision, noticeable within a few weeks. Other symptoms can include color disturbances, and metamorphopsia (distortions in which straight lines appears wavy). Hemorrhaging of the new blood vessels can accelerate the onset of symptoms of CNV. CNV may also include feeling of pressure behind the eye.
The advanced “wet” form (neovascular or exudative) of AMD may frequently cause a rapid and often substantial loss of central vision in patients. In the wet form of AMD, choroidal neovascularization forms and develops into a network of vessels that may grow under and through the retinal pigment epithelium. As this is accompanied by leakage of plasma and/or hemorrhage into the subretinal space, there could be severe sudden loss of central vision if this occurs in the macula. The present disclosure contemplates treatment or prevention of AMD, wet AMD. In some embodiments, methods and pharmaceutical compositions as disclosed herein are used to treat AMD.
In some embodiments, methods described herein are used to prevent or treat an ocular disease or disorder in a subject who has received prior treatment with bevacizumab, brolucizumab, ranibizumab, faricimab, abicipar pegol, conbercept, OPT-302, KSI-301, injectable sunitinib maleate (GB-102), PAN-90806 (PanOptica), and/or aflibercept. In some embodiments, methods described herein are used to prevent or treat an ocular disease or disorder that is responsive to treatment with bevacizumab, brolucizumab, ranibizumab, and/or aflibercept.
In some embodiments, the individual was diagnosed with the ocular neovascular disease at least 1 day, at least 1 week, at least 1 month, at least 2 months, at least 4 months, at least 6 months, at least 12 months, at least 18 months, at least 24 months, at least 30 months, at least 36 months, at least 42 months, at least 48 months, at least 54 months, at least 60 months, at least 66 months, at least 72 months, at least 78 months, at least 84 months, at least 90 months, 96 months, at least 102 months, at least 108 months, at least 114 months, at least 120 months, at least 126 months, at least 132 months, or more, prior to administration of the unit dose of rAAV particles to the one eye and/or the contralateral eye.

Intravitreal (IVT) administration of anti-vascular endothelial growth factor (VEGF) (such as aflibercept) is the standard of care for neovascular age-related macular degeneration. A shortcoming of these therapies is the need for frequent injections associated with fluctuation in central subretinal fluid ultimately impacting best corrected visual acuity. Therefore, there is an urgent need to develop new VEGF long-acting therapeutic modalities. To date, a single IVT injection of ADVM-022 has resulted in robust levels of aflibercept at therapeutic concentrations out as long as 104 weeks, as demonstrated in an ongoing, long-term clinical study, OPTIC. Both the aforementioned study and the current, non-clinical study described here utilize ADVM-022, an adeno-associated virus (AAV) gene therapy vector encoding aflibercept packaged in the chimeric AAV.7m8 capsid. ADVM-022 has been shown to reduce annual injection frequency by >80%, and in most patients eliminate the need for any additional injections of anti-VEGF. Previous non-clinical studies demonstrated a nearly flat dose response suggesting a lower dose could also yield efficacious aflibercept levels.
To assess whether lower doses of ADVM-022 provide relevant ocular aflibercept levels we performed a good laboratory practice (GLP) toxicology study using non-human primates (NHP). In this study, NHP subjects were administered bilateral IVT ADVM-022 at either 3E10 vg/eye or 1E11 vg/eye (n=4/group), or vehicle (n=2/group). Vitreous (VH) and aqueous humors (AH) were collected for aflibercept quantification on days 30, 60 and 98 post dose. See
An ELISA detection assay was used to measure Aflibercept levels in non-human primate aqueous and vitreous humors. Briefly, 1 μg/mL of capture reagent (rhVEGF165, R&D Systems, Cat #293-VE-500) was diluted in coating buffer (R&D System, Cat #DY006) and coated onto a 96-well microtiter plate overnight at 2-8° C. The next day, the plate was washed with wash buffer (KPL, Cat #5150-0011) and blocked with protein-free blocking buffer (Pierce, Cat #37572) for at least 60 minutes at room temperature. This was followed by a wash step. Aflibercept standards (Eylea, Regeneron, Cat #NDC 61755-005-55) ranging from 10 ng/ml to 0.078 ng/ml and samples diluted to at least 1:50 in reagent diluent (1×PBS and 1% BSA, Pierce, Cat #A9576-50 mL) were loaded on the plate and incubated for 2 hours at room temperature with shaking at 200 rpm followed by a wash step. Subsequently, a detection antibody, horse radish peroxidase- (HRP-) conjugated mouse-anti-human IgG Fc (Jackson ImmunoResearch, Cat #209-035-098) was added to the plate and incubated for 2 hours at room temperature with shaking at 200 rpm and then washed. The plate was developed using SuperSignal ELISA Pico Chemiluminescent HRP substrate (ThermoFisher, Cat #37069) and read on a SpectraMax M3 plate reader (Molecular Devices). Luminescence is plotted versus aflibercept concentration.
Administration of ADVM-022 at both doses resulted in meaningful aflibercept levels with peak aflibercept levels at approximately 4-weeks post dose. Mean peak aflibercept levels at the 3E10 vg/eye dose were 0.942 μg/mL for VH and 0.535 μg/mL for AH. At the 1E11 vg/eye dose, mean peak aflibercept levels were 1.339 μg/mL for VH and 0.834 μg/mL for AH. These peak levels were comparable with aflibercept levels observed in previous studies utilizing higher doses of ADVM-022. See Tables 2 and 3.
Overall IVT administration of ADVM-022 in NHP subjects was well tolerated. No adverse systemic clinical signs were observed during the 3-month study. In life observations were dose-dependent and limited to non-adverse slight to mild dose-dependent ocular inflammation characterized by pigment and cells in the VH. No abnormalities of the anterior segment or lens were found, and no iris changes were observed by transillumination. Microscopic findings were limited to minimal mononuclear cell infiltrations, considered non-adverse based on minor severity, in agreement with absence of abnormal findings in ocular physiology and function in animals.
In summary, the findings from the non-clinical NHP study suggest administration of ADVM-022 at doses as low as 3E10 vg/eye (human equivalent dose of 6E10 vg/eye) may provide therapeutic levels of aflibercept in the clinic.
NHP tissues collected at termination of the in life part of the study intended for vector genome DNA analysis were snap frozen on dry ice and stored at −80° C.
During collection of tissue samples for mRNA analysis, instruments were wiped with RNaseZap™ Wipes from ThermoFisher or similar before use. Tissue samples collected for mRNA analysis were incubated in RNAlater at (2 to 8° C.) for 24 hours, in RNAse and DNAse free tube and then the RNAlater was discarded. After that tissues were transferred to dry ice or a freezer set to maintain −80° C.
Tissues for the vector DNA and mRNA biodistribution analysis included: ciliary body with iris (right and left), cornea (right and left), choroid (right and left), lens (right), optic nerve (right and left), lateral geniculate nucleus (left), optic chiasm (left part), optic tract (left), spleen, salivary glands (right and left), lymph nodes (left mandibular and mesenteric), eyelid (right and left), liver (left lateral lobe), heart (left ventricular), kidney (right and left), lung (left caudal lobe), testis (right and left), cerebellum (left), and visual cortex (right and left). For vector genome DNA analysis, whole blood was collected to venipuncture to K2EDTA tubes and frozen over dry ice or in a freezer set to maintain-80° C., within 60 minutes of blood collection. For the RNA analysis, blood samples were collected to RNAprotect Animal Blood Tubes (QIAGEN or similar). Blood samples were placed on dry ice within 60 minutes of collection and stored in a freezer set to maintain −80° C. until analysis.
Vector DNA biodistribution was measured by quantitative polymerase chain reaction (qPCR). The number of vector DNA copies were inferred from a copy number standard curve and calculated per microgram (μg) of tissue DNA. In brief, Total DNA was extracted from Cynomolgus monkey tissue and blood using QIAsymphony DSP DNA mini kit on QIAsymphony. qPCR reactions were performed on 96-well plates. Each plate was run with a standard curve, a set of QC samples, and study samples. The forward primer (ADVM-022F) sequence was 5′-GAGTGACAATGACATCCACTTTG-3, (SEQ ID NO: 42). The reverse primer (ADVM-022R) sequence was 5′-AGACTCCAGTATCCCAGTATGA-3′ (SEQ ID NO: 43). The ADVM-022 probe sequence (ADVM-022P) was 5′-6FAM-AAACTTGGACCTGGGAGTGGACAC (SEQ ID NO: 44)-MGBNFQ-3′. The standard curve was run in 3 replicates for the standard points at 106, 105, 103, 102, 50, 20, 10, and 0 copies per reaction. The 0 copy standards, containing only matrix, were included to confirm reagent purity. Triplicate QC samples were prepared at 105 (QC high), 104 (QC mid), and 103 (QC low) copies/reaction in a background of 1,000 ng Cynomolgus monkey matrix DNA per reaction. When possible, the tissue DNA samples were tested at 1,000 ng per reaction and the blood DNA samples were tested at 100 ng per reaction. The blood DNA was tested at a lower reaction based on previous observations that 1,000 ng of blood DNA per reaction inhibited qPCR. If it was not possible to load the amounts specified above for a specific sample (because the DNA concentration was too low or the sample volume was limiting), a smaller amount of sample DNA was analyzed. All sample reactions were run in triplicate, and the third reaction was spiked with 200 copies of pAVA210 DNA to evaluate potential qPCR inhibition. If qPCR inhibition was observed as shown by the measured value in the third spiked well at less than 110 copies of the target DNA, the sample DNA were reanalyzed at lower amount.
Transgene mRNA expression analysis was performed using RTqPCR method. In brief, RNA was purified from Cynomolgus monkey tissue samples using test site operation procedures, and cDNA was synthetized using the Maxima H Minus cDNA Synthesis Master Mix. TaqMan-based RT-qPCR reactions were performed on 96-well plates. Each plate was run with a standard curve, 2 sets of QC samples, and study samples. The standard curve was run in 3 replicates using serial dilutions of pAVA266-Flip pFB-C11-AfliCo plasmid, at 107, 106, 104, 103, 50, 25, 10, and 0 copies per reaction. The 0 copy standards were included to confirm reagent purity. Duplicate QC samples were prepared at 106 (QC high), 104 (QC mid), and 103 (QC low) copies/reaction of pAVA266-Flip pFB-C11-AfliCo, mRNA DNA per reaction. The analyses utilized following set of primers. The forward primer AfliCo-F1 sequence was 5′-TGCCCGCACCTATTGAAAAG-3′ (SEQ ID NO: 45). The reverse primer AfliCo-R1 sequence was 5′-GAGGCTCGCGAGGTTGAC-3′ (SEQ ID NO: 46). The AfliCo-P1 Probe sequence was 5′-6-FAM-CATCTCCAAGGCCAAG-MGBNFQ-3′ (SEQ ID NO: 47). When possible, the tissue cDNA samples were tested at 10 ng per reaction. If it was not possible to load the amount specified above for a specific sample (because the DNA concentration was too low or the sample volume was limiting), a smaller amount of sample DNA was analyzed. As a control to monitor the vector DNA contamination in the isolated RNA samples, each RNA sample was analyzed in a single well by qPCR at 10 ng of total RNA per well. As another control to monitor overall RNA integrity, relative quantitation of the monkey housekeeping gene Hprt1 cDNA, was also performed in duplicate qPCR wells.
ADVM-022 vector genome DNA and transgenic mRNA microscopic distribution in ocular compartments were evaluated using BaseScope In-Situ Hybridization Methods (ISH). For the analysis, upon eye enucleation, the cornea, iris and lens were removed from the globes. The remaining posterior segment and isolated anterior structures were fixed in 10% neutral buffered formalin for 24 hours and stored in 70% ethanol up to 72-hours. The tissues were prepared for paraffin embedding using vacuum infiltration processing and placed into paraffin blocks and stored at 4° C. until sectioning. Transverse sections of the posterior segment were collected through the macula at 5-μm thickness and mounted on charged slides. Transverse sections of the isolated anterior structures were collected at 5-μm thickness and mounted on charged slides. Slides were stored at 4° C. until shipment to Advanced Cell Diagnostics (ACD). Ten sequential slides were shipped to ACD for subsequent in-situ hybridization (ISH) analysis. ISH was performed using the BaseScope LS Red Reagent Kit (Cat. No. 323600) following optimized pretreatment conditions which included epitope retrieval of 15 minutes at 88° C., and protease III treatment for 15 minutes at 40° C. ISH labeling of ADVM-022 vector genome DNA was performed using a 1-ZZ paired probe to the sense of the CMV promoter. Results from one such experiment are shown in
This Example describes a Phase 2 study to assess the safety, tolerability, and efficacy of AAV2.7m8-aflibercept, an rAAV vector containing the VEGF inhibitor aflibercept and the AAV2.7m8 protein capsid, in anti-VEGF treatment-experienced patients with neovascular (wet) age-related macular degeneration (nAMD).
This study is designed to evaluate the safety, tolerability and efficacy of a single intravitreal injection of AAV2.7m8-aflibercept at two dose levels (6×1010 vg/eye and 2×1011 vg/eye) in patients with nAMD that have persistent retinal fluid and a demonstrated response to aflibercept. The objectives and endpoints of this study are provided below.
The primary objectives of this study include:

For assessment of secondary endpoints, baseline measurements are based on pre-injection values at the Screening visit in which aflibercept is administered.
The study population includes male and female participants, 50 years or older, diagnosed with active choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD) and have a history of responsiveness to anti-VEGF treatment.
Prior to the Screening visit (Baseline), eligible participants have received: a minimum of 2 anti-VEGF injections in the previous 4 months, anti-VEGF injections for no more than 3 calendar years (36 months) prior to Baseline, and no anti-VEGF injection in the 28 days prior to receiving aflibercept at Baseline.
Individuals that meet the following criteria are included in this study:
Individuals that meet any of the following general criteria are excluded from the study:
Individuals that have history or evidence of any of the following ocular criteria in the study eye are excluded from the study:
This study is a Phase 2, multi-center, randomized, double-masked, parallel group study evaluating two dose levels of AAV2.7m8-aflibercept (2×1011 vg/eye [A] or 6×1010 vg/eye [B]) accompanied by evaluation of the safety and anti-inflammatory effectiveness of four prophylactic corticosteroid treatment regimens (topical [1], intravitreal [2], topical+oral [3], or intravitreal+oral [4]) (Table 1). Eligible study participants are randomized in a 1:1:1:1:1:1:1:1 ratio. Only one eye per participant is selected as the study eye. If both eyes are eligible the eye with the worse BCVA at Day −7 is the study eye. If both eyes have the same BCVA, the study eye is the right eye. See,
All randomized study participants have study visits at Day 1, Day 3, Day 8, Week 2, Week 4, Week 6, Week 8, Week 10, and then every 4 weeks through Week 50. The primary analysis is performed at Week 50/EOS. All participants that complete the study through Week 50 are requested to take part in a separate long-term extension study with continued safety monitoring.
a Topical is Durezol 0.05% difluprednate ophthalmic emulsion eyedrops.
b Ozurdex ® is dexamethasone intravitreal implant, 0.7 mg.
c Oral is oral prednisone tablets, USP.
Eligible participants received their last standard of care (SOC) anti-VEGF injection at least 28 days prior to receiving the IVT aflibercept injection at Baseline.
Eligibility for randomization into the study period involves two or more study visits and may last up to 21 days prior to administration of AAV2.7m8-aflibercept at Day 1. At the Screening Visit (one or more visits between Day −21 and Day −14) blood is collected for the purposes of assessing neutralizing antibody (nAb) titers and blood chemistries, and a single intravitreal injection of aflibercept (2 mg in a 0.05-mL intravitreal injection) is administered for the purpose of assessing a meaningful anatomic response to aflibercept anti-VEGF treatment. The Screening Visit at which aflibercept is administered is considered Baseline and occurs at least 28 days after the participant's last standard of care (SOC) anti-VEGF injection. Evidence of sufficient intraretinal and/or subretinal fluid at Baseline that, in the opinion of the Investigator, would justify a 50 μL intravitreal injection of aflibercept to treat the active primary or recurrent subfoveal choroidal neovascularization (CNV) or CNV with subfoveal involvement with fluid is required. Approximately 7-14 days after the Screening Visit, eligibility by nAb titer and IVT aflibercept response is confirmed at the Randomization Visit (Day −7). Potential participants with nAb titers of 1:125 or higher and/or no meaningful anatomic response to IVT aflibercept ˜7-14 days after receiving the aflibercept injection at the Screening Visit are excluded.
A meaningful anatomic response is determined if any of the following three criteria are met at the Randomization Visit, as confirmed by Central Reading Center (CRC) and agreed upon by the Investigator:
Eligible participants based on nAb titer and anatomic response to aflibercept are randomized to one of the 8 treatment arms (see, Table 1). The identity of the dose assignment is concealed by identical appearance, packaging, labeling and schedule of administration to mask the participant, the Investigator, and clinical staff.
Randomized participants begin their assigned prophylactic corticosteroid regimen at the Randomization Visit/Day −7 (i.e., 7 days prior to AAV2.7m8-aflibercept dosing on Day 1).
Prophylactic corticosteroid therapy to be evaluated with each AAV2.7m8-aflibercept dose includes either a 22-week topical difluprednate regimen (Durezol) (Arms 1A & 1B), IVT dexamethasone implant (Ozurdex®) applied as a single in-office injection (Arms 2A & 2B), a combination of the 22-week topical difluprednate regimen with a 10-week oral prednisone regimen (Arms 3A & 3B), or a combination of IVT Ozurdex® applied as a single in-office injection with a 10-week oral prednisone regimen (Arms 4A & 4B).
Participants assigned to treatment Arm 1 (Arms 1A & 1B) and Arm 3 (Arms 3A & 3B) self-administer topical difluprednate 0.05% (Durezol® USPI) eye drops daily for 22 weeks with a slow taper. The taper ends with a self-administered dosing frequency of 1 drop every other day for the last 4 weeks (Table 2).
Tapering of corticosteroid eye drop administration frequency is only reduced according to the taper described in Table 2, and only in the absence of active inflammation. If corneal complications from use of topical difluprednate occur, consult with Medical Monitor. For participants who experience an elevation in IOP secondary to difluprednate use, focus is on utilizing IOP lowering medications to control IOP while maintaining the difluprednate dosing schedule. If this is not possible, the Medical Monitor is consulted.
Participants assigned to treatment Arm 2 (Arms 2A & 2B) and Arm 4 (Arms 4A & 4B) receive an in-office IVT injection of Ozurdex® (dexamethasone intravitreal implant, 0.7 mg) at Day −7. Intravitreal injection of Ozurdex® is administered after all other study-required assessments have been completed.
It is recognized that IVT injection of Ozurdex® (like all IVT injections) may result in acutely elevated intraocular pressure (IOP). To monitor participant safety, a post-injection safety assessment is performed immediately after administration of prophylactic IVT Ozurdex® implant. Treatment of post-injection elevated IOP, if required, is per Investigator discretion. Furthermore, in certain steroid-responsive individuals, elevated IOP may be encountered weeks to months after injection. IOP is monitored as part of all post-injection follow-up visits. Elevated intraocular pressure is treated at the discretion of the Investigator. The Medical Monitor is consulted in cases where the IOP cannot be controlled with routine use of IOP-lowering medications.
Participants assigned to treatment Arm 3 (Arms 3A & 3B) and Arm 4 (Arms 4A & 4B) self-administer oral prednisone daily at a dose based on body weight at the Screening visit for 10 weeks according to the schedule below (Table 3).
aFor participants in the body weight range ≥70 kg, Week 9 dosing includes taper to 10 mg/day for 4 days followed by 5 mg/day for 3 days
On Day 1, eligible participants receive an injection of AAV2.7m8-aflibercept administered intravitreally in the study eye (7 days after starting their assigned prophylactic corticosteroid regimen). The identity of the AAV2.7m8-aflibercept dose assigned to a participant is masked to the Investigator, clinical staff, and the participant. If the participant receives an Ozurdex® injection, the AAV2.7m8-aflibercept ocular injection is in a quadrant at least 90° from the quadrant in which Ozurdex® is injected. Participants return for study visits on Days 3 and 8, Weeks 2, 4, 6, 8, 10, and every 4 weeks thereafter through Week 50, for clinical evaluation.
Participants are assessed for the need of supplemental aflibercept treatment starting at Week 4. The first supplemental aflibercept injection (if required) occurs no sooner than Week 4 and requires any of the following criteria to be met:
The above criteria are considered prior to administration of any supplemental aflibercept treatment (initial and subsequent injections). Central Reading Center confirmation of meeting the CST criteria is not required prior to administration of a supplemental aflibercept treatment after the initial supplemental injection. Aflibercept is not injected in eyes with active inflammation.
Total study duration is up to 53 weeks, including a 3-week screening period prior to Day 1, and a 50-week study period following dosing with AAV2.7m8-aflibercept. The primary analysis is performed at Week 50/end of study.
All participants who complete the study through Week 50 may take part in a long-term extension study with continued safety monitoring.
Efficacy of AAV2.7m8-aflibercept is evaluated based on the following assessments:
Refraction and BCVA are measured using an ETDRS visual acuity chart at a starting distance of 4 meters, prior to dilating eyes or any examination requiring contact with the eye, or administration of ocular treatment.
SD-OCT imaging assessments are performed using the same equipment for all study visits of a participant. SD-OCT images are submitted to the CRC for determination of participant eligibility at Screening, as well as for determination of need for supplemental aflibercept as required throughout the Study Period.
The safety of AAV2.7m8-aflibercept is assessed through the collection of adverse events (AEs), vital signs, physical examinations, ocular examinations, imaging, and laboratory evaluations.
Components of the full ophthalmic examination performed in this study are described in Table 4.
In the event of significant intraocular inflammation (IOI), low IOP, and/or vision loss, gonioscopy is performed as part of the full ophthalmic examination if feasible.
The post-injection assessment is performed on the study eye 0-5 minutes and 30±15 minutes following IVT aflibercept injection (Screening and/or supplemental), prophylactic IVT Ozurdex® implant injection, and/or IVT AAV2.7m8-aflibercept injection. The post-injection assessment involves an assessment of vision (e.g., count fingers) and measurement of IOP. Direct visualization to assess the central retinal artery, presence of retinal detachment, or presence of new intraocular hemorrhage may be performed.
Fundus Autofluorescence (FAF) imaging is performed to assess occurrence of geographic atrophy.
Additional assessments include Color Fundus Photography (CFP), Optical coherence tomography (OCT) images of the optic nerve head and retinal nerve fiber layer, and Fluorescein Angiography (FA).
Additional ocular examination and imaging assessments are captured in the presence of significant intraocular inflammation, as described below.
The following additional assessments and procedures are performed during this study.
Aqueous humor (AH) samples are collected during the study. AH samples are only collected if considered safe for the participant (as determined by the Investigator) and if the participant's IOP at the time of sampling is >10 mmHg.
AH samples are collected to determine aflibercept levels, e.g., at Week 10, Week 26, and Week 50/EOS study visits. In addition, AH samples are obtained prior to administration of the first supplemental aflibercept injection so long as it occurs at Week 10 or later. Following the first supplemental aflibercept injection, regularly scheduled AH sampling occurs if the visit happens at least 12 weeks after the most recent aflibercept injection.
An AH sample is obtained upon the occurrence of a participant's first episode of significant intraocular inflammation so long as the participant's IOP at the time of sampling is >10 mmHg and the Investigator believes it safe to obtain an AH sample in the presence of IOI. This sample is for the assessment of cells/material in the anterior chamber. Furthermore, if significant IOI exists, further samples of AH for aflibercept levels are not obtained until the inflammation has resolved for at least 12 weeks.
Anti-drug antibodies (ADA) are assessed in participant serum samples. ADA assessments include total antibodies to AAV.7m8 and neutralizing antibodies to AAV.7m8.
Presence of total anti-AAV.7m8 antibodies (TAbs) are measured in serum (and aqueous humor, where possible) in a ligand binding assay. Presence of neutralizing anti-AAV.7m8 antibodies (NAbs) is measured in serum (and aqueous humor, where possible) in a cell-based assay. NAb titer is measured in serum at Screening for the purpose of assessing participant eligibility. Participants with a serum Nab titer 1:125 or higher are excluded from participation in the study.
Humoral response against aflibercept is measured in serum (and aqueous humor, where possible) in a ligand binding assay.
Cellular immunity against AAV.7m8 capsid and aflibercept protein is assessed in whole blood in an enzyme-linked immune absorbent spot (ELISpot) assay.
Presence of total aflibercept protein is measured in serum (and aqueous humor, where possible) in a ligand binding assay.
Tears from both eyes and whole blood are collected from a subset of participants. Viral shedding samples are collected after AAV2.7m8-aflibercept has been injected, and continue to be collected until 3 consecutive samples (for both blood and tears of both eyes) have tested negative for viral shedding. Samples are analyzed by quantitative-Polymerase Chain Reaction (q-PCR) for evidence of viral shedding related to AAV2.7m8-aflibercept.
A Participant Preference Survey (PPS) is provided to participants for completion at the Week 26 and Week 50/EOS/or ET visit. The PPS is designed to gather feedback on participants' experience with study treatment and includes items on willingness to receive study treatment in the fellow eye and ability to manage the assigned steroid regimen. If a participant cannot complete the survey due to vision-related or other reasons, it may be administered by a study site staff member.
If vitrectomy is medically necessary, a vitreous humor sample may be obtained. Vitreous humor samples are analyzed primarily for aflibercept concentrations. The remaining samples may be analyzed for other biomarkers. If any other surgical procedures become medically necessary in the study and/or fellow eye during the course of the study, other ocular tissues may be provided, including aqueous or vitreous humor and lens, to be analyzed for other biomarkers.
The safety population includes all participants who have received AAV2.7m8-aflibercept, and are analyzed according to the dose received. AEs are coded using the MedDRA (Most Recent Version) classification to give a preferred term (PT) and system organ class (SOC) for each event.
The efficacy analysis endpoints are analyzed at Week 26 (primary timepoint) and Week 50. Efficacy analyses include all subjects with study treatment and at least one post-study assessment. Baseline values for endpoints refer to measurements taken at the Screening Visit in which aflibercept was administered.
The primary efficacy endpoint, change in BCVA in ETDRS letters from baseline at Week 50/EOS, is analyzed by mixed model repeated measures (MMRM).
Concomitant medications are any prescription or over-the-counter drugs other than study protocol-specified procedural medications and pre- and post-IVT injection medications used by a participant 30 days before Screening/Baseline until the participant's EOS or ET visit.
At the discretion of the evaluating physician, participants may continue to receive all medications and standard treatments administered for other conditions except for treatments noted in the exclusion criteria described above and as noted in the prohibited medications below.
The following medications are prohibited during the study:
Individuals with visually significant cataracts are not randomized or enrolled in the study. However, if a cataract develops during the study, cataract surgery in the study eye may be performed if clinically indicated and is scheduled no sooner than 3 months after AAV2.7m8-aflibercept injection at Day 1, and/or no sooner than 7 days after the last injection of supplemental aflibercept, and/or no sooner than 3 months after the resolution of active intraocular inflammation. Participants may continue on the study after cataract surgery. Individuals who develop AMD in the fellow (non-study) eye may receive standard of care therapy.
The reporting period for adverse events (AEs), serious adverse events (SAEs), and adverse events of special interest (AESIs) begins at the time a subject signs the informed consent form until a participant completes the study, discontinues prematurely, or withdraws consent. If a participant discontinues prematurely after receiving AAV2.7m8-aflibercept, AEs are recorded until discontinuation or 30 days after the last study visit, whichever is later. Between the time of informed consent and study treatment administration, only AEs (non-serious and serious) assessed as related to study procedures are reported. After treatment administration (Day 1), all clinically significant AEs are reported. Each participant is followed until a) the end of the AE reporting period at 30 days after the last study visit or b) when any ongoing AAV2.7m8-aflibercept-related AEs and/or SAEs have resolved or become stable. Any clinically significant safety assessment that is associated with nAMD is not reported as an AE or SAE, unless judged by the Investigator to be more severe than expected for the subject's condition.
Participants that reach Week 50 are invited to participate in a separate long-term extension study with continued safety monitoring. Participants that received AAV2.7m8-aflibercept are followed for at least 5 years from date of AAV2.7m8-aflibercept dosing or until they are lost to follow-up, whichever occurs first.
An AE is any untoward medical occurrence in an enrolled participant regardless of its causal relationship to AAV2.7m8-aflibercept, including but not limited to: abnormal laboratory findings or clinical tests, including those that worsen from baseline and are clinically significant in the medical and scientific judgment of the Investigator; any new disease or exacerbation of an existing condition; recurrence of a sporadic medical condition (e.g., fever) not present at Screening/Baseline; adverse events related to a study protocol-mandated intervention, including those that occur prior to study treatment (e.g., aflibercept injection).
An SAE is any untoward medical occurrence in an enrolled participant, regardless of its causal relationship to AAV2.7m8-aflibercept, that results in death, a life-threatening condition, inpatient hospitalization or prolongation of existing hospitalization, or persistent or significant disability or incapacity or is a congenital anomaly or birth defect. Important medical events that may not meet these criteria may be considered SAEs when, based on appropriate medical judgment, they may jeopardize the participant or may require medical or surgical intervention to prevent one of the outcomes listed in above. All malignant neoplasms are assessed as serious in the category of “medically significant” if other seriousness criteria are not met. Any suspected transmission of an infectious agent by a medicinal agent is also considered a serious adverse event. Development or progression of a cataract and/or cataract surgery is not considered reportable as an SAE, unless the cataract or cataract surgery results in permanent disability.
Adverse events of special interest (AESIs) include sight-threatening adverse events in the study eye. An adverse event is sight-threatening if it meets one or more of the following: it causes a decrease of ≥30 letters in BCVA using an ETDRS visual acuity chart compared with the prior visit and is not associated with worsening of cataract; it requires surgical or medical intervention (e.g., conventional surgery, vitrectomy) to prevent permanent loss of sight (e.g., IOP>30 mmHg or ≤5 mmHg); and/or it causes severe intraocular inflammation (e.g., endophthalmitis [presumed infectious], papillitis, choroiditis, retinitis, vasculitis, or grade 3+ or 4+ anterior chamber cell/flare, vitreous cells/haze, or vitritis).
The Medical Dictionary for Regulatory Activities (MedDRA) is used to code all AEs.
Events are considered related to AAV2.7m8-aflibercept if there is a reasonable possibility of a causal relationship rather than if a causal relationship cannot be ruled out. When assessing causality, Investigators assess biological balancing (i.e., the probability that the suspect drug caused the AE must be weighed against the probability that an alternative candidate caused it).
Additional ocular examination and imaging assessments are captured in the presence of active intraocular inflammation and/or significant vision loss (greater than or equal to 15 letters loss from Baseline).
If any new, worsening, or recurrent intraocular inflammation (with or without low intraocular pressure) is observed, additional assessments are collected to fully characterize inflammation location and severity. In all cases of new intraocular inflammation (with or without low intraocular pressure) BCVA and a full ophthalmic examination including slit lamp biomicroscopy, indirect ophthalmic exam, and IOP, as well as SD-OCT, are performed to assess the intraocular inflammation and/or pressure. The iris is carefully examined for the presence of transillumination defects, and slit lamp photos are obtained if present.
