The application generally relates to pharmaceutical compositions that are useful for the treatment of subjects in risk for or having breast disorders and estrogen-related disorder and methods of using such compositions.
There are 2.5 million women alive in U.S., who have a history of breast cancer, of which approximately 70% of human breast cancers are hormone-dependent and estrogen receptor-positive (ER+) and 88% are post-menopausal. Typically, treatment is interventional (surgery, chemotherapy, radiation) followed by adjuvant therapy when appropriate. A significant improvement in post-surgical survival and a reduction in disease relapse has been observed, especially in women with early stage breast cancers and those with ER+ tumors, who receive adjuvant systemic therapy with Selective Estrogen Receptor Modulators (SERMs), Selective Estrogen Receptor Downregulators (SERDs) or Aromatase Inhibitors (AIs) alone or in combination with cytotoxic therapy.
Tamoxifen, the first SERM to be approved by FDA for the treatment and prevention of breast cancers, is available as an oral formulation either as a once a day pill (Novaldex™) or in liquid formulation (Soltamax®). While tamoxifen acts as an antiestrogen in breast tissue, it also functions as an estrogen-agonist in a variety of other tissues, for example, in bone and in ovary. Due to the systemic presence of tamoxifen, women undergoing treatment with tamoxifen experience disease relapse and severe side effects that include endometrial and ovarian cancer, blood clots, deep vein thrombosis, bone loss and osteoporosis, and stroke. Concerns regarding tamoxifen-related toxicity limits its use as a preventive agent and has been the driving force for the search for other SERMs with less toxicity and the development of 4-Hydroxytamoxifen (4-OHT), raloxifene (Trade name: Evista), toremifene (Trade name: Fareston®), bazedofoxifene (Conbriza®), and lasofoxifene (Fablyn®). When used as systemic therapy, these newer SERMs also have severe side effects that include increased risk of venous thromboembolic events such as deep vein thrombosis and pulmonary embolism, and increased risk of death due to coronary artery heart disease.
Fulvestrant (Trade name: Faslodex), a non-steroidal antiestrogen that binds and targets the estrogen receptor for destruction is the best studied amongst the SERDs, and is approved by FDA for the treatment and prevention of breast cancer as a once a day pill in an oral formulation. Unlike tamoxifen, fulvestrant rarely has estrogen-like like effects on bone and ovary. However, the women undergoing treatment with fulvestrant experience severe gastrointestinal symptoms and bone pain.
Currently, several AI drugs (anastrozole (Aridimix®), exemestrane (Arosmasin®), and letrozole (Femara®)), are the treatment of choice for postmenopausal women. Although results from meta-analyses of AI monotherapy and sequenced therapy (switch from tamoxifen to AI) clinical trials show that disease-free survival was significantly improved, and that overall survival was prolonged for patients who switched from tamoxifen to AI therapy, risk of fractures and muscle and bone pain is significantly increased with AI.
The first line therapy with systemic SERMs, SERDs, and AI thus results in low compliance, low adherence, and low persistence (Nonadherence to Adjuvant Tamoxifen Therapy in Women with Primary Breast Cancer, Partridge et al., J. Clinical Oncology, Vol. 21, Feb. 15, 2003; Adherence to Initial adjuvant anastrozole therapy among women with early stage breast cancer, Partridge et al., J. Clinical Oncology, Vol. 26, No. 4, Feb. 1, 2008; Early Discontinuation and Non-adherence to Adjuvant Hormonal Therapy in a Cohort of 8,769 Early Stage Breast Cancer Patients, Hershman et al., Journal of clinical Oncology, vol. 26, No. 27, Sep. 20, 2010, all of which are hereby incorporated by reference for all purposes).
Accordingly, there is a need to develop compositions and formulations containing SERMs, SERDs and AI for the treatment and prevention of breast and reproductive tract disorders that have high potency and efficacy and reduced toxicity profile. Local, effective, easy to administer diagnostic tests and chemotherapy would obviate the side effects of systemic treatment and could produce higher levels of treatment compliance with drugs with improved efficacy.

Each API and excipient used herein may be discussed interchangeably with respect to its chemical formula, chemical name, abbreviation, etc. For example, HPMC may be used interchangeably for hydroxypropyl methyl cellulose. Additionally, each polymer is described herein, unless designated otherwise, includes homopolymers, copolymers, terpolymers, and the like.
As used herein and in claims, the term “amount,” “effective amount,” and “therapeutically effective amount” may be used interchangeably and is used to describe an amount of the pharmaceutical composition that treats, totally or partially, the progression of a disorder or alleviates, at least partially, one or more symptoms of the disorder. A therapeutically effective amount can also be an amount that is prophylactically effective. The amount that is therapeutically effectively will depend upon the patient's size and gender, the disorder or condition to be treated, the severity of the condition and the result sought. For a given patient and condition, a therapeutically effective amount can be determined by methods known to those skilled in the art.
As used herein, the term “analog” means a chemical compound that is structurally similar to another.
As used herein, the term “dosage form” means the form in which the drug is delivered to the patient. The dosage form means the composition delivered to a subject in any form suitable for parenteral, topical, oral, transdermal, intraductal delivery.
As used herein, the term “composition” and “preparation” may be used interchangeably unless the context suggests otherwise.
The terms “subject,” “patient,” and “individual,” may be used interchangeably herein and refer to a mammalian, such as a human.
As used herein, and in the claims, the terms “comprising,” “containing,” and “including” are inclusive, open-ended and do not exclude additional unrecited elements, compositional components or method steps. Accordingly, the terms “comprising” and “including” encompass the more restrictive terms “consisting of” and “consisting essentially of:”
It is specifically understood that any numerical value cited herein includes all values from the lower value to the upper value, i.e., all possible combination of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application. For example, if a concentration range or beneficial range is stated as 1% to 50%, it is intended that values such as 2% to 40%, 10% to 30%, or 1% to 3% etc., are expressly enumerated in this specification. As another example, a stated concentration of 20% is intended to include values from 19.5% to 20.5%. Yet another example, if a ratio of 1:10 to 10:1 is stated, then it is intended that ratios such as 1:9 to 9:1, from 1:8 to 8:1, from 1:7 to 7:1, from 1:6 to 6:1, from 1:5 to 5:1, from 1:4 to 4:1, from 1:3 to 3:1, from 1:2 to 2:1, from 1:1 to 2:1 or from 2:5 to 3:5 etc. are specifically intended. There are only some examples of what is specifically intended. Unless specified otherwise, the values of the constituents or components of the compositions are expressed in weight percent of each ingredient in the component.
As used herein, and in the claims, the terms “treat,” “treating,” “treatment” as used herein may be used interchangeably and means that a pharmaceutically effective amount of a composition would be administered, which will inhibit, or at least partially arrest or partially prevent or suppress estrogen or inflammation, or reduce a symptom, delay onset, or inhibit recurrence of a breast disorder or an estrogen-related disorder.
For example, the treatment may include a treatment that can suppress or delay the recurrence of breast disorder. The treatment is particularly effective in that once a day dose, such as a transdermal dose or intraductal dose, is administered to a subject, the subject will continue to receive a therapeutically effect dose for the intended duration of the dose (e.g., a week, a month, 6 months or even a year). The treatment is especially beneficial for younger (e.g., <40 years) and older (e.g., >75 years) women who are at a heightened risk for non-compliance and also for those who may be at a greater risk for development or recurrence of breast cancer. The treatment is particularly beneficial for prevention of breast disorder in women who have at least two (2) family members with a history of breast cancer.
As used herein, the term “hydrophilic” describes that something “likes water” i.e., a hydrophilic molecule or portion of a molecule is one that typically is electrically polarized and capable of forming hydrogen bonds with water molecules, enabling it dissolve more readily in water than in oil or other “non-polar” solvents.
As used herein, the term “hydrophobic” denotes a compound tending to be electrically and neutral and thus preferring other nonpolar solvents or molecular environments. In the present context, the term “amphiphilic” describes a molecule (as a surfactant) having a polar water-soluble group attached to a water insoluble hydrocarbon chain. Thus, one end of the molecule is hydrophilic (polar) and the other is hydrophobic (non-polar).
As used herein, the term “vehicle” means any solvent or carrier fluid in a pharmaceutical product that has no pharmacological role. For example, water is a vehicle for xilocaine, and polypropylene glycol is the vehicle for many antibiotics.
As used herein, the term “penetration enhancer” or “permeation enhancer” means an agent known to accelerate the delivery of the drug through the skin. These agents can also be referred to as accelerants, adjuvants, and absorption promoters, and are collectively referred to herein as “enhancers.” Penetration enhancers according to the present invention are introduced in a non-irritating and/or non-sensitizing amount.
As used herein, the expression “non-irritating” and/or “non-sensitizing” refers to amounts and/or types of excipients used which the skilled person in the art would consider to be well-tolerated by the human skin, i.e., dermatologically acceptable. Using common general knowledge, the skilled person can determine non-irritating and/or non sensitizing amounts of an excipient, for example, a penetration enhancer or an adhesive. In some embodiments, the non-irritating and/or non-sensitizing amount results in no detectable or sustained dermal adverse reaction (e.g., itching, reddening, burning sensation), or results in only a minimal reaction that is generally deemed to be acceptable by patients and health care providers.
As used herein, the term “hydroalcoholic” refers to a substance or a composition that comprises both water and alcohol.
As used herein, the term “gelling agent” means a composition or a substance that when dissolved suspended or dispersed in a fluid (for e.g., an aqueous fluid such as water or a buffer solution) forms a gelatinous semi-solid (e.g., a lubricant gel). Examples of gelling agents include but are not limited to hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxypropyl guar, methyl cellulose, ethyl cellulose, hydroFulose, carbomers, alginates, gelatin, and poloxomer.
As used herein, the term “excipient” refers to an inactive ingredient (i.e., not pharmaceutically active) added to a preparation of an active ingredient. The gelling agent and penetration enhancers for example can generally be referred to as excipients.
As used herein, the terms “controlled-release” refers to the release of a therapeutic agent in a way that deviates from immediate release. As used herein, the terms “sustained-release” and “extended-release” are used interchangeably and refer to the release of the administered therapeutic agent over a longer period of time than a comparable immediate release formulation, resulting in levels of the therapeutic agent or an API in the affected tissues elevated over baseline for a longer period of time than for a comparable immediate-release formulation. The foregoing terms optionally include delayed release characteristics. For example, a delayed release type of controlled-release formulation will be characterized by C at a time greater than C for an immediate release formulation. For example, the released of a therapeutic agent such as 4-OHT will preferably be at such a rate that total ductal, blood or serum levels of 4-OHT are maintained or elevated above the pre-dosing levels for an extended period of time, e.g., 4 hours to 24 hours or even longer.
As used herein, the term “bioavailability” denotes the degree to which a drug or other substances becomes available to the target tissue after administration. As used herein, the term “bioequivalency” denotes a scientific basis on which generic and brand name drugs are compared to one another. For example, drugs are bioequivalent if they enter circulation at the same rate when given in similar doses under similar conditions. Parameters often used in bioequivalence studies are tmax, Cmax, AUCo-infinity, AUCo-r. Other relevant parameters may be W50, W75 and/or MRT. Accordingly, at least one of these parameters may be applied when determining whether bioequivalence is present.
As used herein, the term “NAF” denotes breast duct fluids obtained by nipple aspiration and/or ductal lavage.
As used herein, the terms “condition,” “disorder,” and “disease,” may be used interchangeably.
As used herein, the terms “estrogen-related disorder” and “estrogen-receptor disorder” may be used interchangeably and includes, without limitation, disorders with high estrogen levels or normal estrogen levels that need to be reduced, disorders with estrogen-receptor positive (ER+) and/or progesterone-receptor positive (PR+) disorders, for example, breast disorders, endometriosis, uterine fibroids (also called leiomyomas) etc.
As used herein, “breast disorder” means any aberration or a constellation of aberrations in the breast. Such aberration may be proliferative or non-proliferative. Breast disorders include benign lesions of the breast (hyperplasia) and breast cancer. Benign breast lesions include, but are not limited to, ductal hyperplasia, lobular hyperplasia, atypical ductal hyperplasia, and atypical lobular hyperplasia.
As used herein, “breast cancer” means any malignant tumor of breast cells. There are several types of breast cancer. Exemplary breast cancers include, but are not limited to, ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS), invasive (or infiltrating) lobular carcinoma (ILC), invasive (or infiltrating) ductal carcinoma (IDC), microinvasive breast carcinoma (MIC), inflammatory breast cancer, ER-positive (ER+) breast cancer, ER-negative (ER−) breast cancer, HER2+ breast cancer, triple negative breast cancer (TNBC), adenoid cystic (adenocystic) carcinoma, low-grade adenosquamatous carcinoma, medullary carcinoma, mucinous (or colloid) carcinoma, papillary carcinoma, tubular carcinoma, metaplastic carcinoma, or micropapillary carcinoma. A single breast cancer tumor can be a combination of these types or be a mixture of invasive and in situ cancer.
Ductal hyperplasia is a hyperplasia of a breast duct, not accompanied by histomorphologic abnormalities. Ductal hyperplasia is not usually considered predictive of a predisposition for breast cancer.
Lobular hyperplasia is a hyperplasia of a breast lobule, not accompanied by histomorphologic abnormalities. Lobular hyperplasia is not usually considered predictive of a predisposition for breast cancer.
Atypical ductal hyperplasia (ADH) is a benign lesion of the breast characterized by hyperplasia of at least one breast duct and histomorphologic abnormalities. While not cancerous, ADH may be indicative of a predisposition for breast cancer. ADH may be excised by lumpectomy.
Atypical lobular hyperplasia (ALH) is a benign lesion of the breast characterized by a hyperplasia of a breast lobule and histomorphologic abnormalities. While not cancerous, ALH may be indicative of a predisposition for breast cancer. ALH may be excised by lumpectomy.
Ductal carcinoma in situ (DCIS) is the most common non-invasive breast cancer. It involves the cell lining the breast ducts. In DCIS, the cells have not spread beyond the walls of the duct into the surrounding breast tissue. About 1 in 5 new breast cancer cases will be DCIS.
Lobular carcinoma in situ (LCIS) is a pre-cancerous neoplasia. It may be indicative of a predisposition for invasive cancer. LCIS only accounts for about 15% of the in situ (ductal or lobular) breast cancers. LCIS is often treated with SERMs, predominantly tamoxifen.
Invasive Ductal Carcinoma (IDC) is the most invasive breast cancer. As the name applies, it is a carcinoma that begins in the breast ducts and then invades the surrounding fatty tissue. About 8 to 10 invasive breast cancers are infiltrating ductal carcinomas. IDC is often treated by surgery to excise the cancerous tissue, and radiation therapy. In addition, chemotherapy combined with immunotherapy (e.g., tamoxifen and tratuzumab) is often used to treat DC. If the tumor is larger than 4 cm, then a radial mastectomy may be performed.
Invasive Lobular Carcinoma (ILC) is a cancer that develops in the lobules of the breast and has invaded the surrounding tissue. About 1 in 10 invasive breast cancer is an ILC. ILC is treated by surgery to excise the cancerous tissue, and radiation therapy. In addition, chemotherapy and immunotherapy combination (e.g., tamoxifen and tratuzumab) is often used as an adjuvant therapy to treat ILC.
Inflammatory breast cancer accounts for about 1% to 3% of all breast cancers. In inflammatory breast cancer, cancer cells block lymph vessels in the skin resulting in the beast turning red and feeling warm. The affected breast may become larger or firmer, tender, or itchy. Inflammatory breast cancer is treated with chemotherapy, immunotherapy, radiation therapy and in some case, surgery.
ER+ breast cancer is characterized by the presence of estrogen receptors on the surface of the cancerous cells. Growth of ER+ cancer cells is associated with the availability of estrogen. Treatment options for ER+ breast cancer include chemotherapeutic agents that block estrogen (e.g., tamoxifen).
HER2+ breast cancers are characterized by an excess of HER2 on cell surface of the cancerous cells. HER2+ cancer is often treated with trastuzumab in combination with additional chemotherapeutic agents.
Triple Negative Breast Cancer (TNBC) is a breast cancer characterized by cell which lack estrogen receptors and progesterone receptors, and do not have an excess of the HER2 protein on their surface. TNBC are often more invasive than other breast cancers. Because the tumor cells lack estrogen and progesterone receptors, hormone therapy (e.g., tamoxifen) by itself is not effective. Additionally, as the cells lack the HER2 protein, drugs that target HER2 (e.g., trastuzumab) are ineffective.
The compositions and formulations disclosed herein are useful for the treatment of subjects in risk for or having any estrogen-related disorder or a breast disorder. In one aspect, the compositions and formulations disclosed herein may be used to treat subjects at risk for or having an estrogen-related disorder. In some embodiments, subjects have high estrogen levels or normal estrogen levels that need to be reduced. In other embodiments, the subjects have estrogen-receptor positive (ER+) and/or progesterone-receptor positive (PR+) disorders, for example, breast disorders, endometriosis, uterine fibroids (also called leiomyomas), etc. In yet other embodiments, the subjects have estrogen-receptor positive (ER+) and/or HER2 positive (HER2+) disorders.
In some embodiments, the compositions disclosed herein may be used to treat breast disorders, including, without limitation, benign lesions of a breast, and breast cancer. In some preferred embodiments, the breast disorder is selected from a group consisting of ductal hyperplasia, lobular hyperplasia, atypical ductal hyperplasia, atypical lobular hyperplasia, ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS), invasive (or infiltrating) lobular carcinoma (ILC), invasive (or infiltrating) ductal carcinoma (IDC), microinvasive breast carcinoma (MIC), inflammatory breast cancer, ER-positive (ER+) breast cancer, ER-negative (ER−) breast cancer, HER2+ breast cancer, triple negative breast cancer (TNBC), adenoid cystic (adenocystic) carcinoma, low-grade adenosquamatous carcinoma, medullary carcinoma, mucinous (or colloid) carcinoma, papillary carcinoma, tubular carcinoma, metaplastic carcinoma, and micropapillary carcinoma. In a preferred embodiment, the disorder is a combination of the foregoing breast disorders. In a more preferred embodiment, the breast disorder is a mixture of invasive and in situ cancer. In one aspect, the breast disorder is a malignant tumor of breast cells. In another aspect, the breast disorder includes conditions where the breast tissues express increased levels of HER2. In a preferred embodiment, the breast disorder is hyperplasia.
Without being bound by a particular theory of operation, precancerous hyperplasia of the breast is “driven” by a number of processes. A significant process is the contribution of stimulation of the estrogen/progesterone hormonal axis. Each menstrual cycle, during the proliferative phase and especially week two of the cycle, blood levels of estrogen increase significantly, driving ductal cell division and growth. Following ovulation, if fertilization does not occur, there is involution of the ductal and lobular changes and return to quiescence until the next cycle. Estrogen from systemic sources, mostly from ovaries, as well as local synthesis within the breast from the action of aromatase on testosterone contribute to the growth. A second major stimulation is the generalized effect of a pro-inflammatory environment. This has been considered by some to be effect of stromal effects on the ductal epithelium. A third stimulation involves the role of “metabolic” drivers, such as glucose driven metabolism and high mitochondrial activity in the process. Fourth, a general role for vitamin D as a driver in the regulation of a wide range of cellular mechanisms central to cancer development, such as apoptosis (cell death), cell proliferation, differentiation, angiogenesis and metastasis has been suggested. Finally, HER2 stimulation and oncogene and tumor promoter activation can contribute to either inducing hyperplasia or sustaining it.
Given the drivers of precancerous hyperplasia, certain classes of effectors may be used to prevent or reverse the hyperplasia, and treat estrogen-related disorders and breast disorders. For example, SERMs, SERDs, and AIs may block the effects of the estrogen surge. Given further the increased inflammation, heart disease, bone loss and osteoporosis resulting from the current adjuvant systemic therapy with tamoxifen, raloxifen, etc., pharmaceutical compositions of the present invention combining these SERMs, SERDs, and/or Ms with omega-3 fatty acids and vitamin D may provide a solution to the unmet need for new pharmaceutical compositions, formulations and treatment methods that prevent or treat subjects at risk for development or recurrence of ER+ disorder and/or breast disorder, reduce these toxic effects, particularly inflammation, cardiac health, bone loss and osteoporosis and/or enhance patient compliance.
The present invention provides pharmaceutical compositions for the prevention and/or treatment of a subject in risk for or having an estrogen-related disorder or a breast disorder that reduce the risk of developing, progressing or recurring ER+ disorders and/or breast disorders and also reduce systemic effects of the SERDs, SERMs and/or AI. The compositions disclosed herein are capable of being delivered locally at rates of delivery ranging from rapid delivery to slow or sustained delivery with little to no systemic blood concentrations of therapeutic agents.

The backing layer may be a cloth, non-woven fabric, polyurethane, polyesters such as polyethylene terephthalate, ethylene-vinyl acetate, polyvinyl acetate, polyvinylidene chloride, polyethylene, for example, low density polyethylene and high density polyethylene, polyethylene terephthalate, an aluminum sheet, rayon, and a combination or a composite thereof. Backing layers that are polyethylene terephthalate-aluminum-polyethylene composite are also suitable.
In some embodiments, a device may further comprise a release liner, which may optionally be rate-limiting. In some embodiments, a composition may be applied or coated onto the release liner. Non-limiting examples of release liner include a vinyl chloride film, a polyethylene film, a polypropylene film, a polyester film, polyethylene-coated paper coated with a suitable fluoropolymer or silicone based paper, a polyethylene terephthalate separator according to a pharmaceutical additive specification, and a release paper (exfoliate paper). A pharmaceutical composition as disclosed herein can be dissolved, dispersed or suspended into a suitable vehicle as described above and coated on to the release liner. The release liner is then dried and laminated onto a backing using conventional methods.
In other embodiments, the transdermal drug delivery device such as a patch may comprise at least two distinct layers in addition to the backing layer. A first layer comprising a composition described herein is attached to the backing layer and serves as a drug reservoir (a reservoir layer). The second layer, (i.e., a rate controlling layer), comprises a pressure sensitive adhesive layer that is attached a surface of the first layer opposed to a surface in contact with the backing. The rate-controlling layer serves to attach to a subject's skin (a skin contacting layer) and controls the rate of delivery of the drug to a subject.
In yet other embodiments, the transdermal drug delivery device comprises at least three distinct layers in addition to a backing layer. A first layer comprising a composition disclosed herein is attached to the backing layer and serves as a drug reservoir (a reservoir layer). A second layer (i.e., a rate controlling layer) comprises a rate-controlling membrane that is attached to a surface of the first layer opposed to a surface in contact with the backing layer. A third layer comprises a pressure sensitive adhesive that is attached to a surface of the membrane that is opposed to the surface of the membrane in contact with the first layer. The third layer contacts a skin of a subject when the device is used. This third layer is referred to as the “skin-contacting layer.”
Adhesive layer typically comprises an adhesive formulation. Pressure sensitive adhesives in the adhesive formulation may be any adhesive that is useful for transdermal drug delivery. Preferably, such an adhesive is non-irritating, biocompatible and compatible with other components of the adhesive formulation, and biodegradable. Non-limiting examples of adhesives have been described above. The pressure sensitive drug delivery adhesive may be same or different from that used for transdermal drug delivery formulation used in the drug reservoir. In some embodiments, the pressure sensitive adhesive used in the rate-controlling layer is the same as that used in the reservoir layer. In other embodiments, the pressure sensitive adhesive used in the skin-contacting layer (third layer) is the same as that used in the drug reservoir layer.
Preferably, the pressure sensitive adhesives used in the skin-contacting layer comprise polymers selected from the group consisting of acrylates, natural rubbers, and synthetic rubbers.

I. Oral Dosage Forms
In another aspect of the invention, pharmaceutical compositions are formulated for oral delivery. An oral dosage form can be of any shape suitable for oral administration, such as spherical (0.05-5 mL), oval (0.05-7 mL), ellipsoidal, pear (0.3-5 mL), cylindrical, cubic, regular and/or irregular shaped. In some embodiments, the oral formulation is a capsule, a caplet, or a tablet. When the oral dosage form is a tablet, the tablets for example may be disintegrating tablets, fast-dissolving tablets, effervescent tablets, fast melt tablets, and/or mini-tablets.
When the dosage form is a capsule, in at least one preferred embodiment, the capsule is a seamless capsule. In other preferred embodiments, the capsule is a hard capsule or a soft capsule. In a more preferred embodiment, the capsule is a gelatin capsule, gelatin-free capsule, a “cap-in-cap” capsule, alginate capsule, hydroxypropylmethyl cellulose (HPMC) capsule, a polyvinyl alcohol (PVA) capsule, or a starch capsule.
An example of a “cap-in-cap” capsule is a DuoCap™. DuoCap involves specialist filling techniques using custom designed filling equipment that allows the insertion of a pre-filled, smaller capsule into a larger liquid-filled capsule. The smaller, inner capsule may contain either a liquid or a semi-solid formulation and, according to the formulation or product requirements, either or both capsules may be of gelatin or HPMC composition and can be coated, if necessary. DuoCap™ has been successfully commercialized by Encap and is suitable for the purposes of the present invention.

In one aspect, gelatin ranges from 1% to 80% by weight with respect to the total weight of the shell. In another aspect, the gelatin Bloom strength in the soft gelatin capsule is typically 150 to 200 Blooms (or grams). The Bloom strength in the hard gelatin capsule is adjusted higher than that of the soft gelatin capsule, 200-300 Blooms. Viscosity of the a hard capsule is preferably from 44 to 60 mPa while the viscosity of a soft gel capsule is preferably from 2.8 to 4.5 mPa, depending on the type of gelatin used.
The gelatin may be from an animal or a non-animal source. In an aspect, the gelatin capsule comprises a gelatin selected from type A gelatin, type B gelatin, and mixtures thereof. Gelatin is produced by destruction of secondary and to some extent higher structures of collagen. Two common processes by which collagen is processed to form gelatin include the acidic and the alkaline pre-treatment followed by extractions. Type A gelatin is extracted from the animal skin or hide and soaked in acid for 10-30 hours depending on the nature of the collagen stock. Type B gelatin is derived from collagen raw materials subjected to alkaline pre-treatment and left in liming pits for 3-10 weeks depending on the nature of the stock and ambient temperature.
In some preferred embodiments, the capsules are made of non-animal materials or plant materials. In one aspect, a non-animal capsule comprises starch which is formulated with conventional plasticizers such as glycerol, sorbitol etc., (10% to 60% w/w of dry shell) and water to form a molten mass that can be extruded to set within less than 20 seconds producing a mechanically strong, elastic film on temperature-controlled casting drums. Sealing is performed at temperatures between 25° C. and 80° C. Starch may be obtained from any source, for example vegetables such as potato. In some embodiments, the amylopectin content is 50% w/w.

J. Capsule Preparations
Capsule shells may be made using any of the methods known in the art, for example, by using the plate process, the rotary die process, the reciprocatory die process, the Norton capsule machines and Accogel capsule machines (McGuffy, Irena, Softgel Technology as a Lipid-Based Delivery Tool for Bioavailability Enhancement, Catalent Pharma Solutions, Somerset, N.J., March 2011). Exemplary manufacturers of soft and hard gelatin capsules include Catalent Pharma Solutions, Somerset N.J., Pharmagel Engineering spa, Lodi, Italy, and Soft Gel Technologies Inc., Commerce, Calif., CapsuGel, Inc., Morristown, N.J., Eli Lilly, Ind. Manufactures of HPMC capsule shells include Shionogi Qualicaps (QUALI-V), Vegicaps (Catalent).
A brief method of making a soft gelatin capsule shell follows.
A desired amount of gelatin (150 Blooms for a soft shell) is mixed with water. A plasticizer such as sorbitol or glycerin or a combination of both, is added to the mix of gelatin and water and melted in a heated tank (gelatin melter) typically for about 3 hours until gelatin turns into a molten liquid gel mass. Optionally, opacifier, a coloring agent, or flavor mask may be added to the mix prior to melting the gelatin. The gel mass is taken in a closed clean environment for cooling and storage. As sheets of gelatin are formed, two flat ribbons may be manufactured using twin set of rotary dies which contain recesses in the desired size and shape. The rotary dies cut out the ribbons into a two-dimensional shape, and form a seal around the outside. At the same time, a pump may deliver a precise dose of fill phase into the shells through a nozzle incorporated into a filling wedge, whose tip sits between the two ribbons in between two die pockets at the point of cut out. The wedge is heated to facilitate the sealing process. The wedge injection causes the two flat ribbons to expand into the die pockets, giving rise to the three-dimensional finished product. After encapsulation, the soft gel capsules are dried for two days to two weeks depending on the product and polished.
The capsule shell is provided with at least one coating. The coating may be provided in any manner suitable, for example, by passing through fluidized air beds or horizontal drums, spraying or dipping in a coating onto a surface of a capsule shell, and the like. As a non-limiting example, a desired amount anastrozole may be mixed with alcohol (e.g., ethanol or isopropanol) and a film-forming agent (e.g., HPMC) and stirred until anastrozole is completely dissolved in the film-forming agent such that each capsule will deliver a fixed predetermined amount of anastrozole to a subject, for e.g., 0.5 mg or 1 mg per capsule. The film-forming agent comprising anastrozole may be next sprayed onto the surface of the capsule shell. Alternatively, the capsule shell may be dipped into film-forming agent comprising anastrozole. The capsule is then dried, polished, and stored in an appropriate dispenser, such as a light and airtight bottle.
To prepare an exemplary fill phase of a gelatin capsule, ethanol is added to isopropanol to prepare alcohol mixture and stirred. A fatty acid mixture comprising at least one omega-3 fatty acid in a triglyceride form, for example EPA triglyceride, is added to an ethanol/isopropanol mixture while stirring under nitrogen. A surfactant such as glycerol may optionally be added to the mixture. Next, at least one vitamin D compound, Cholcalciferol, is slowly added to the fatty acid mixture comprising the omega-3 fatty acid triglyceride until completely dissolved. Fish oil is added in sufficient amounts to a desired final weight of the fill phase formulation. The solution is sterilized by filtration using typically one or two filters of 0.2 μm porosity. The sterile filtrate is kept under N2 overlay as it is filled into a capsule shell.
In another embodiment, a desired amount of cholecalciferol is added to commercially available purified omega-3 fish oil and filled into a capsule shell prepared as described above. Optionally, anti-oxidant, such as alpha-tocopherol, may be added to the purified omega-3 fatty acid triglyceride fish oil.
As another example, a soft gelatin capsule may be prepared as described above. A fill phase may be prepared as described. To the fill phase, anastrozole dissolved in an alcoholic solvent such as alcohol such as ethanol and isopropyl alcohol, may be added to the fatty acid mixture comprising at least one omega-3 fatty acid, and at least one vitamin D compound such as cholecalciferol.
Accordingly, in one aspect, a method of preparing a pharmaceutical preparation is provided comprising preparing a mixture of: (a) at least one therapeutic agent: (b) a fatty acid mixture comprising at least one omega-3 fatty acid; (c) at least one vitamin D compound; (d) and optionally, an excipient.

NAF samples are useful for diagnosis and classification of breast disorders (U.S. Patent Application Pub. No. 2013/0115629, and U.S. Patent Application Pub. No. 2013/0130310, each of which is incorporated herein by reference in its entirety).
In one aspect, a method of treating a subject is provided wherein the method comprises: (a) collecting NAF sample from the subject: (b) testing NAF sample; (c) determining the subject's breast condition; (d) based on the breast condition, administering to the subject a composition comprising (i) at least one therapeutic agent; (ii) a fatty acid mixture comprising at least one omega-3 fatty acid; and (iii) at least one vitamin D compound. The test methods for assessing the effectiveness of a composition in the prevention and treatment of the breast disorders and estrogen-related disorders and/or the prognosis comprises measuring any number of genetic markers and other biomarkers in a subject over time, including, without limitation, presence of cells, cell free DNA (cfDNA), RNA, lipids, glycolipids, carbohydrates, proteins in nipple aspirate fluid (NAF) samples, changes in mean breast density, changes in biomarker expression (e.g., CK5, CK14, CK7, CK19, p53, uPA, PAI, and Gal-GalNac), etc. Other non-limiting examples of biomarkers useful for diagnostic tests (for example, for cell adhesion and/or cell motility markers such as Cathepsin D, plasminogen activators and collagenases) are disclosed in U.S. Pat. No. 6,610,484, U.S. Pat. No. 6,287,521, U.S. Pat. No. 6,689,073, U.S. Pat. No. 6,887,210, and U.S. Pat. No. 7,128,877, the disclosures of which are hereby incorporated in its entirety in the present application.
In some embodiments, methods comprising testing of NAF comprises collecting NAF sample from a subject, contacting a cell of the NAF sample adsorbed to device such as a slide or an adsorbent paper comprising antibodies or other reagents that bind to or otherwise identify biomarkers including, without limitation, cytokeratins such as CK5, CK14, CK7, CK18, Cyclin B1, MUC1, tumor suppressors such as p53, uPAR, PAI, and Gal-Gal-NAc. Binding of one or more antibodies to the cell is detected and the data is analyzed using various computer algorithms. For example, the presence of p63 would indicate the presence of basal-like breast cancer. In some embodiments, the presence of CK5/CK14 and CK7/CK18 would be indicative of usual ductal hyperplasia. In other embodiments, the presence of CK7/CK18, and reduced or negative presence of CK5/CK14 would be indicative of atypical ductal hyperplasia or DCIS. In other embodiments, increase in CK7/CK18 would indicate the presence of breast cancer, specifically luminal breast cancer. Invasive breast lesion would be indicated by a reduction in the number of or the absence of myopeithelial cells (CK1/CK14 and/or p63) and the presence of glandular epithelial cells (CK17/CK18). Primary breast carcinomas for example, would be indicated by an increase in luminal (duct-wall) cells and a decrease in the number of myoepithelial cells. In some embodiments, the absence or reduction in the number of myopeithelial cells and the presence of glandular cells would be indicative of invasive lesion.
Accordingly, in at least one embodiment, a method of treating a subject in need thereof comprises a test conducted on NAF sample comprising: a) collecting a NAF sample from a subject; b) contacting a cell of the NAF sample adsorbed to an adsorbent paper comprising antibodies that bind to CK5, CK14, CK7, CK18, and p63; c) detecting binding of one or more of the antibodies to said cell; and d) classifying cancer based upon the binding pattern of the antibodies. In some embodiments, the adsorbent paper comprises antibodies that bind to uPAI, PAR and Gal-GalNac.
Other diagnostic tests include measurement of total protein, evaluating the cytology (for e.g., cell shape, size, chromatin content, nucleus:cytoplasm ratio, etc.).
In other embodiments, the cells isolated from the NAF sample may be maintained or cultured in a laboratory to study its growth pattern and determine their propensity for uncontrolled proliferation. These cells may also be used for isolation and sequencing of subject's DNA (including mitochondrial DNA), RNA (including without limitation, micro-RNA, 16S RNA) and subjected to testing for the presence or absence of breast disorder biomarkers.
Breast disorder biomarkers are useful for classification of breast disorders, screening, diagnosing and monitoring progression of a breast disorder (or a lack thereof), and include, without limitation, identifying the presence or absence of gene mutations, single nucleotide polymorphisms (SNPs), gene or DNA copy number alterations or variations, alterations in DNA methylation patterns or signatures, histone methylation patterns or signatures, changes in micro-RNA patterns, 16S RNA sequences, altered micro-biome, altered expression of cancer biomarkers, for example, without limitation, BRCA1, BRCA2, etc. Various commercially available cancer gene panels (for example, BROCA test from University of Washington, Seattle, Wash., BRACAnalysis from Myriad Genetics, Inc. UT) are known in the art and are useful for the purpose of the present invention. In another aspect, a diagnostic test may comprise analysis of micro-RNA (MiRNA) in a patient sample, for example, the NAF. Recent studies on miRNA profiling have revealed differential expression of miRNAs in breast carcinomas compared to their normal tissue counterparts. For example, an increase in miR-155, miR-21, miR-27, miR10b expression would indicate the presence of breast cancer. In some embodiments, a decrease in miR-125 (a and b), miR145 and miR205 would be indicative of breast cancer. In some embodiments, an increase in miR-155, miR-21, miR-27, miR10b and a decrease in miR-125 (a and b), miR145 and miR205 would be indicative of breast cancer. In other embodiments, decrease in miR-140, a tumor suppressor, would be indicative of DCIS and/or IDC and suggest increased breast cancer progression.
In one aspect, the methods of screening, diagnosing, and monitoring for the presence or absence of gene mutations include, without limitation, sequencing of individual genes or a panel of genes or gene clusters by dideoxy, Sanger sequencing, next generation sequencing, single cell sequencing, single nucleus sequencing, single molecule real time sequencing, whole genome sequencing, exome sequencing, RNA sequencing from single cells, microarray analysis, PCR, etc. Based on the results of the tests, a subject's responsiveness to treatment, prognosis, or likelihood of developing such disorders or recurrence may be determined or predicted. The dose and/or the treatment regimen may be then be established and/or adjusted based on the test results.
In some embodiments, methods comprise a test conducted on NAF sample is selected from a group consisting of gene mutations, single nucleotide polymorphisms (SNPs), copy number, DNA methylation patterns or signatures, histone methylation patterns or signatures, micro-RNA patterns, micro-biome pattern, and cancer biomarkers.
In other embodiments, methods comprise a test conducted on NAF sample comprising: a) collecting a NAF sample from a subject; b) conducting a single nucleus sequencing of a cell of the NAF sample; c) determining the risk for, presence, or reoccurrence of a cancer; and d) administering a therapeutically effective amount of a composition to the subject.

In some embodiments, methods disclosed herein require less than 100 cells, less than 50 cells, less than 10 cells, less than 9 cells, less than 8 cells, less than 7 cells, less than 6 cells, less than 5 cells, less than 4 cells, less than 3 cells, less than 2 cells. More preferably, these methods require 2 cells. Even more preferably, these methods require a single cell. Methods requiring a single cell are particularly advantageous in performing diagnostic tests using techniques such as single nucleus sequencing on samples from subject using non-invasive methods.

C. MiRNA
In another aspect, the at least one additional medication administered to a subject in combination with the compositions disclosed herein may comprise micro-RNA (MiRNA), upregulators or downregulators of miRNA, or a combination thereof. Recent studies on miRNA profiling have revealed differential expression of miRNAs in breast carcinomas compared to their normal tissue counterparts. For example, miR-155, miR-21, miR-27, miR10b, are upregulated and oncogenic in nature while miR-125 (a and b), miR145 and miR205 were downregulated. Other studies have shown that miR-140 serves as a tumor suppressor in both DCIS and IDC through interactions with SOX2 and SOX9, and loss of MiR-140 expression results in increased breast cancer progression. As non-limiting examples, the compositions of the present invention may be administered to a subject in combination with miR-125a, miR-125b, miR200, miR145, miR205, mi146a, let-7a-d, miR-26a, miR34, miR31miR-101, miR200b, miR-335, miR-126, miR-206, miR-17-5p and miR-140 or upregulators thereof.

D. DNA Methylation Modulators
In another aspect, the at least one additional medication administered to a subject in combination with the compositions disclosed herein may comprise, DNA methylation modulators. Aberrations in DNA methylation and in the proteins involved in DNA methylation are known to occur in cancer; for example, hypermethylation of tumor suppressor genes (Radpour et al., PLoS ONE, January 2011, 6:1 e16080), aberrant expression of DNA methyltransferase-1 (DNMT1) and other DNMTs (Baylin et al., Hum. Mol. Genet. 2001, 10:687-692), and hypomethylation of unique genes and repetitive sequences (Soares et al., Cancer. 1999 Jan. 1; 85(1):112-8; Ehrlich M., Oncogene 2002, 21:5400-5413). Accordingly, the present invention encompasses compositions and treatment methods that comprise administering DNA methylation modulators in combination with the compositions of the present invention.

In a preferred embodiment, at least one additional medication is selected from a group consisting of 5-Azacytidine, 5-aza-2′-deoxycytidine, and MG98.
In some embodiments, the DNA methylation modulator is a DNA methylation activator. In a preferred embodiment, the DNA methylation activator is S-Adenosylmethionine (SAM) (Luo et al., Human Gastric Cancer and Colon Cancer. Int. J. Biol. Sci. 2010; 6(7):784-795). DNA hypomethylation in breast carcinoma is correlated with prognostic factors and tumor progression.
In one aspect, the subject's DNA methylation profile or signature is determined from cancer samples such as breast tissue sample, NAF and ductal fluid samples and blood or serum samples, prior to treatment by methods known in the art, such as bisulfite mapping, methylation sensitive PCR or methylation-sensitive restriction analyses of specific cancer genes. Several methylated genes and cancer genes are known in the art, including, without limitation, BRCA1, BRCA2, APC, BIN1, CST6, GSTP1, P16, P21, ESR-b, CIMP, and TIMP3. In a preferred embodiment, the subject's DNA methylation profile or signature is determined on a sample selected from a group consisting of breast tissue, NAF and ductal fluid and blood samples.
In another aspect, a subject's DNA methylation signature may be determined using whole genome approaches such as single nucleus sequencing, multiplex sequencing, next generation sequencing (NGS) of bi-sulfite covered DNA (Lister et al., Nature 2009, 462:315-322), methylated DNA immunoprecipitation (MeDIP) followed by either hybridization to high density oligonucleotide arrays (Keshet et al., Nat Genet. 2006, 38:149-153) or NGS (Ruike, Y et al., BMC Genomics 2010, 11:137), and dedicated Illumina 27K and 450K arrays that measure the state of methylation of well-characterized CG sites distributed in the genome (Bibikova et al., Genomics 2011, 98:288-295). In some embodiments, a subject's methylated DNA may be enriched prior to DNA methylation mapping.

It should be understood that various alternatives to the embodiments of the invention described herein may be employed in practicing the invention. It is intended that the following claims define the scope of the invention and that methods and structures within the scope of these claims and their equivalents be covered thereby.
This example provides the composition of a gel-formulated preparation according to the present disclosure and as shown below in Table 2.
This example provides the composition of a gel-formulated preparation according to the present disclosure and as shown below in Table 3.
This example describes the preparation of Anastrazole soft gelatin capsules and analyses thereof according to an aspect of the present disclosure.
A gel mass is prepared as follows: Acid-insoluble polymer, Eudragit R L30D 55 will be dissolved in water-alkali vehicle. Triethyl citrate will be added. The film-forming agent, gelatin (lime bloom, 150 Bloom) will be mixed with plasticizer sorbitol and added to enteric polymer solution, mixed for 2 hours and kept overnight at 60° C. Table 4 provides an exemplar composition.
Gel mass will be cast as a ribbon with 0.03″ thickness on a cold drum (10° C. to 13° C.). Two sets of ribbons will be prepared and a rotary die process is used to cut the ribbons to an appropriate size and shape. The two ribbon pieces are melded together under heat to create a seamed soft gelatin capsule shell.
Next, Anastrozole will be solubilized in ethanol/isopropanol mixture (1:1 v/v). A film forming agents will be prepared by mixing, while stirring, a sufficient amount of a polymer, HPMC, with anastrozole solution at a ratio of anastrozole to HPMC of 45:55. Antifoam A (3 drops) will be added to the mixture. The film-forming agent/anastrozole mixture is sprayed onto an outer surface of capsule shell in amounts sufficient to deliver 0.5 mg of anastrozole/capsule to a subject. Weights of the shell (solid phase) and liquid fill phase will be approximately 150 mg/capsule and 1000 mg/capsule, respectively. The capsule shell is used to encapsulate the fill phase formulation described below.
The permeability of soft gelatin capsule shells will be tested to determine potential leakage of a fill phase formulation from the capsule shell. A dialysis set with two chambers is set up with a capsule shell gel mass ribbon acting as a separator for two chambers. A water soluble dye, methylene blue dissolved in 0.1 N HCl is placed in one chamber. In the second chamber separated by the capsule shell gel mass will be placed 0.1 N HCl without the dye. The dialysis chamber setup will be placed in shaking water bath at 37° C. Samples are removed at periodic time intervals of 10, 20, 30, 45, 60, 90, 120 and 180 minutes. It is expected that up to 60 minutes, no significant release of methylene blue dye will be observed. Any release after 60 min is expected to be less than 10%.
A fill phase formulation is prepared that comprises a fatty acid mixture comprising omega-3 fatty acids, EPA and DHA in triglyceride forms. An alcoholic mixture is prepared by adding ethanol to isopropanol (1:1 v/v) and stirred. A fatty acid mixture comprising EPA triglyceride and DHA triglyceride in 1.2:1 ratio, is hearted to 40° C. to which cholecalciferol (2000 IU), is added until completely dissolved. The fatty acid mixture comprising EPA:DHA triglycerides and cholecalciferol next is slowly added to the ethanol/isopropanol mixture while stirring under nitrogen. Cod fish oil is added in sufficient amounts to ensure complete dissolution of the EPA and DHA triglycerides. The fill phase formulation is sterilized by filtration using typically one or two filters of 0.2 μm porosity. The sterile filtrate is kept under N2 overlay as it is filled into a capsule shell.
The compatibility of the soft gel capsule fill phase formulation will be determined using HPLC/GC analysis with an anastrozole tablet (Arimidex) standard reference. Samples of the soft gelatin dosage forms will be tested at time t=0, 2, and 4 weeks at 40° C. (dry). A parallel study will be performed by holding the fill phase at room temperature for seven days. The fill formulation will be visually inspected for signs of physical stability. Water and plasticizer challenge will be performed by spiking the fill phase with up to 10% water and 5% plasticizer. Dispersion properties in 0.01N HCl and pH 6.8 PBS buffer will be performed. Stability of the formulations at thermal cycling will be studied.
Gel masses made based on Example 3(a) where the enteric polymer and gelatin weight ratio comprise 45% by weight will be manufactured having polymer to gelatin weight ratios of 1:19 (5%), 1:9 (10%) and 1:5.7 (15%). The resulting gel masses will be cast as films and characterized for enteric properties using USP disintegration and dissolution apparatus:
Release rate studies will be performed using USP dissolution paddle system at 50 rpm, 900 mL of Simulated Gastric fluid (no enzymes, “SGF”) and 900 mL of Simulated Intestinal Fluid (no enzymes “SIF”) at 37° C. A continuous flow system will be used to monitor the absorbance at 272 nm (anastrozole) at 1 min intervals over 3 hours. The capsules will be placed into cylindrical cages (1 cm diameter×3 cm long) of 20 inch stainless steel screen.
The release rate studies will be performed using a USP dissolution paddle system at 37° C. The capsules will be subjected to SGF for the first 2 hours, and then the cages will be transferred to the SIF media. Three runs for each capsule will be made and the results will be determined. The release of the drug will be determined using UPLC using a UV detector at 245 nm. No changes of in the absorbance will be indicative of preserved integrity of the coatings.
A patient diagnosed with hyperplasia in two breast ducts (one duct in her right breast; second duct in her left breast) will be treated with endoxifen in a transdermal composition as follows. A subject may be diagnosed with hyperplasia by any method possible, including mammography. In the following non-limiting example, the subject is diagnosed with hyperplasia using the NAF fluid. Sufficient amount of NAF will be collected from each breast of a subject. The sample from each breast will be analyzed using cytology tests and determining the expression pattern of cancer biomarkers CK5, CK14, CK7, CK18, and p53 using antibodies directed against these biomarkers. The analysis will reveal ductal hyperplastic disorder in the two suspect ducts. Each suspect duct will be fitted with a small osmostic pump which will be placed under local anesthetic into the suspect ducts through the ductal orifice and ductal lumen into the lactiferous sinus of each duct which comfortably house each osmostic pump mechanism. A small wire or thread will be left protruding through the accessed duct to identify the pump, and to provide a means to retrieve the pump at a later date. The pumps are filled with gel of Example 1. The pumps will disperse 1 mL of the gel into each duct. The pump mechanism will be tested by aspirating a small portion of the ductal fluid after pump installation to identify an expected amount of endoxifen in the ductal fluid. The ductal cells will be re-analyzed by cytology periodically (i.e., once a week, biweekly, month, etc.) by collecting NAF to determine if the endoxifen composition is effective. The NAF will also be tested for the presence of inflammation markers such as C-reactive protein (CRP), Serum Amyloid A protein (SAA), beta protein-1 (BP1) to identify if omega-3 fatty acids are effective and to decide if the dosage or the release rate needs to be increased or decreased. Serum estradiol levels and endoxifen levels will also be monitored by drawing blood and isolating plasma to determine their systemic levels.
A post-menopausal woman who is mammographically positive and has ductal fluid in her breasts tested as described above will be treated intraductally with fulvestrant. A high-grade DCIS lesion will be identified by cytological analysis in one of her ducts. The test will be accompanied by single nucleus sequencing of a cell from NAF and will be positive for mutations in several breast cancer genes. The nipple connecting the suspect duct will be cannulated and the duct size will be estimated by using progressively bigger galactography needles to determine the lumen size of the orifice and just below the orifice. A microcatheter tube will be inserted into an identified ductal orifice under anesthesia after the orifice is dilated after the use of galactography needles. The microcatheter will be pushed into the ductal lumen until the end of the tube is flush with the nipple surface. The subject will then receive a first administration of a biodegradable fulvestrant hydroalcoholic gel (20 mg/g w/w of gel) of example 2. The amount of gel administered will be dependent on the capacity of the lactiferous sinus and the ductal lumens (typically about 1 mL), and to the best extent possible the duct will be filled with the gel. The dissipation time of the gel will be estimated based on the concentration of the active pharmaceutical ingredients and HPMC in the gel and the volume of the gel delivered to the duct. The subject will be rescheduled for a readministration of more gel at the completion of that time period. The tube will remain in place in order to facilitate the readministration (which will occur at approximately 3 to 6 weeks later).
Each subject will undergo mammography test pre- and post-treatment to measure the effect of the gel on breast density.
Blood and NAF samples will be collected pre- and during treatment at days 0, 7, 14, 21, 28, 35, 42 and 49. Plasma concentrations of estradiol, fulvestrant, for complete blood counts (CMC), bilirubin, serum glutamic-pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase, creatinine, anastrozole, estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), progesterone, sex hormone-binding globulin (SHBG), cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides, fibrinogen, C-reactive protein (CRP) and anti-thrombin III will be measured for determining the safety and efficacy of the composition. NAF samples will be tested for estradiol, fulvestrant, omega-3 fatty acid, cholecalciferol, and cytokeratin expression on NAF cells.
It is expected that plasma estradiol levels will be lower than 5 ng/mL and that the composition and dose will be well tolerated by the subjects. The treatment is not expected to affect FSH, LH or estradiol or progesterone hormone levels.
Thirty one female post-menopausal subjects scheduled for breast cancer surgery will be randomly assigned to 1 of 5 groups. They will receive either oral Arimidex (Astrazeneca) at 1 mg/day, or oral soft gel capsule as outlined in table 4. Treatment will be daily and will last for 4 weeks prior to surgery. The study will evaluate 3 different oral doses of anastrozole (0.5 mg, 1 mg, and 2 mg) with fixed omega-3 fatty acid and cholecalciferol doses taken orally once a day. One subject will receive placebo.
On the day of initiation of the treatment (time=day 0), each subject will undergo mammography test to set up a baseline for breast density. Blood will be drawn to establish the baseline for plasma estradiol concentration. NAF samples will be collected from each subject using a breast pump device, ForeCyte. Thereafter, blood and NAF will be drawn on days 7, 14, 21, 28 of treatment period. On the last day of the treatment, prior to surgery, each subject will undergo mammography test again to determine effect of treatment on the breast density.
During surgery, two samples (1 cm3) of breast tissue will be excised, one tumoral and the other macroscopically normal. They will be immediately frozen in liquid N2 until assayed.
Pre- and post-treatment blood samples will be assayed for complete blood counts (CMC), bilirubin, serum glutamic-pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), alkaline phosphatase, creatinine, anastrozole, estradiol, follicle-stimulating hormone (FSH), luteinizing hormone (LH), sex hormone-binding globulin (SHBG), cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides, fibrinogen, C-reactive protein (CRP) and anti-thrombin III. NAF samples will be tested for changes in the expression of the cytokeratins and tumor markers, if any.
Pre- and post-treatment NAF samples will be used for classification of the cancer type, (for e.g., whether basal or luminal) and the pattern of expression of CK5, CK14, CK7, CK 18, and p63 on NAF cells will be determined. Concentration of anastrozole, omega-3 fatty acids, cholecalciferol and estradiol in the NAF will be measured. On days 7, 14, 21, 28 of treatment period, these tests will be repeated to monitor the effect of the drug on the subject.
Pre- and post-treatment breast density of each breast of the subjects will be determined.
Side effects such as local irritation and inflammation, dizzy spells, cystitis, vaginitis, hot flashes etc., will be monitored. It is expected that plasma estradiol levels will be lower than 5 ng/mL and that the composition and dose will be well tolerated by the subjects. The plasma anastrozole levels are expected to be detectable but its effect is expected to be reduced due to the omega-3 fatty acid and cholecalciferol. The treatment is not expected to affect FSH, LH or estradiol or progesterone hormone levels.
This example describes various skin models for the study of endoxifen permeation.
EpiDerm™ will be incubated for 1 h at 37° C. with 5% CO2 prior to dosing. Each of the EpiDerm™ batch will be used within 3 days of delivery. An IRB approved human skin samples from operating rooms from hospitals will be obtained. The subcutaneous fat from fresh mastectomy and abdominoplasty specimens will be removed and the full-thickness skin will be immobilized to obtain split-thickness skin (STS) using a surgical blade (George Tiemann and co. Hauppauge, N.Y.) or an electric dermatome (robins instrument Inc., Chatham, N.J.). The thickness of STS samples will be measured with an electronic digital μm (Tresna Instruments co. Fuilin, China).
EpiDerm™ and STS samples will be cut into 3 mm×10 mm pieces, placed horizontally on a Cryomold, embedded in a tissue freezing medium (OCT™ compound; Tissue-Tek, Sakura Fintek USA, Torrance, Calif.), frozen in the microtome/cryostat chamber, sectioned at 7 microns and stained with Mayer's hemotoxylin and eosin. Images will be taken with a 20× objective using a Nikon Eclipse optical microscope with a 10μ bar superimposed on the skin images to measure the permeation of endoxifen into the skin.
Strips of porcine sow breasts will be obtained post mortem from a local abattoir prior to cleaning procedure and transported to laboratory in iced HEPES modified Hanks buffered balanced salt solution (HBBS). The freshly excised strips of the porcine mammary papillae will be washed in tepid water and the mammary papilla surrounded by 2 cm×2 cm of abdominal skin will be excised by blunt dissection. Cutaneous fatty tissue will be removed by blunt dissection also and the pieces are maintained in HHBS until set up in diffusion cells.
The in vitro trans-mammary papilla delivery will be tested using the Franz diffusion cell system consisting of 2 separate chambers, a donor chamber and a receptor chamber. The porcine breast samples will be mounted between the cell compartments, the flanges of which will be smeared with high vacuum silicon grease with the mammary papilla located in the center and facing upwards as described by Lee et al. (International J. Pharmaceutics. 2010, 387, 161-166). The 2 chambers will be held together with a clamped to minimize leakage. The receptor chamber has a volume of about 4.3 mL and will be filled with receptor fluid via a sampling arm. Micro-stirrer bars will be added and the complete diffusion cells will be placed on a submersible magnetic stirrer base set up in a water bath at 37° C. When the breast is mounted in the horizontal position, the donor will be sealed with a greased microscope slide and the cell rotated 90° and supported s necessary. After 30 m, 500 μL of the composition will be applied to the surface of the skin by means of a pipette or a spatula in case of the hydroalcoholic gel. The donor compartment will be then occluded with laboratory film (n=4).
After 6 h, the diffusion cells will be dismantled and the breast tissue will be recovered. Excess dose and grease will be wiped away and the diffused are excised and centrifuged at 10,000×g to remove excess solution and gel, cut into approximately 1 mm×1 mm×1 mm cubes with a scalpel and placed into a 5 mL centrifuge tube. Methanol (2 mL) will be added and the tube will be vortex mixed for 30 s before being placed on a rotating blood cell mixer for 30 m. the tubes will then be centrifuged at 10,000×g and the supernatant is decanted into 10 mL glass bottles. Further aliquots of methanol will be added and the extraction process will be repeated twice more before the pooled supernatants will be reduced in a vacuum oven set at 50° C. The residues will be then reconstituted with a 1 mL of HPLC mobile phase.
Samples will be analyzed by reverse-phase liquid chromatography. Analytes will be separated and statistical analyses will be performed on the results. Drug delivery into the papilla oriented vertically will be compared with that delivered into the papilla oriented laterally by means of Wilcoxon match-pairs signed-ranks test, and the combined formulation of the samples will be compared via a Kruskal-Wallis non-parametric ANAOVA test (Instat 3, GraphPad software, CA, USA). Confidence intervals will be set at 95% and p<0.05 is deemed as statistically significant.
This example describes a method for obtaining skin permeation data according to the following test method.
When a transdermal delivery device is evaluated, the release liner will be typically removed from a 2.0 cm2 patch and the patch will be applied to a human cadaver skin and pressed to cause uniform contract with the skin. The resulting patch/skin laminate will be placed patch side up across the orifice of the lower portion of a vertical diffusion cell. The diffusion cell will be assembled and the lower portion will be filled with 10 mL of warm (32° C.) receptor fluid (0.1 M PBS, pH 6.8) so that the receptor fluid contacts the skin. The sampling port will be covered when in use.
The cells will be maintained at 32±2° C. throughout the course of the experiment. The receptor fluid will be stirred by means of a magnetic stirrer throughout the experiment to assure uniform sample, and a reduced diffusion barrier on the dermal side of the skin. The entire volume of the receptor fluid will be withdrawn at specified time intervals and immediately replaced with fresh fluid. The withdrawn fluid will be filtered through a 0.45 μfilter. The last 1-2 mL will be then analyzed for the active ingredients, 4-OHT, desmethyltamoxifen, endoxifen, fulvestrant, and anastrozole. Using HPLC methods (Column: Phenomenex Spherex, 75×4.6 mm, 3 μm particle size; mobile phase: 400:200:400 Methanol:Acetonitrile:Buffer. Buffer will be ammonium acetate solution adjusted to pH 6.6 with acetic acid; Flow rate: 2 mL/min; Detector: UV at 230 nm; Injection volume: 10 μL; run time: 1.9 m). The cumulative amount of the active ingredients penetrating through the skin will be calculated and reported as μg/cm2.
An endoxifen patch may be prepared as follows: A cation salt of endoxifen will be added to an organic or lipophilic solvent such as ethanol, isopropanol, ethyl acetate, methanol, acetone, 2-butanone, toluene, alkanes, and mixtures thereof while stirring until all of endoxifen is dissolved. The dissolved therapeutic agent is added to a fatty acid mixture comprising EPA triglyceride and mixed. To this mixture 6000 IU of cholecalciferol is added while stirring under N2 overlay. To this solution, a copolymer such as SIS block, a permeation enhancer such as ISM provide a coating composition. The mixture is shaken or stirred until a homogenous coating composition is obtained. The resulting composition is then applied to a release liner using conventional coating methods (e.g., knife coating or extrusion die coating) to provide a predetermined uniform thickness of coating composition and dried to remove all traces of solvent. The release liner is then laminated onto a polyurethane backing layer.
Endoxifen patches (20 cm2) will be sealed in pouches (BAREX™/aluminium/polyester or BAREX™/aluminum/paper laminates and stored under conditions of 25° C./60% relative humidity and 40° C./75% relative humidity. The patches will be tested for their drug content and/or their probe tack before storage and after preset storage times of 1 m, 2 m, 3 m, 6 m, 1 yr, and 2 yrs using test methods described below.
The drug content test data will be obtained using the following test method. The liner will be removed from the patches and the patches will be placed in a 120 mL jar. The backing and coating will be extracted using 75 mL of a solution consisting of 75:25 by volume tetrahydrofuran (THF): methanol (MeOH). The samples will be shaken overnight. Dilutions of the samples will be prepared by placing 10 mL of the resulting solutions into 44 mL vials and adding 30 mL of the additional THF:MeOH to each vial. Aliquots of these final dilutions will then be placed in autsampler vials for analysis by Gas chromatography with flame ionization detection (GC-FID) using a J&W DB-5 fused silica capillary column (15 m×0.53 mm i.d., 1.5 μm film of (5%-Phenyl)-methylpolysiloxane) with helium carrier agas.
The tack data will be obtained using a Digital Polyken Probe Tack Test, Model 80-02-01 (Testing Machines Inc., Amityville, N.Y.). The machine settings will be as follows: speed: 0.5 cm/second, dwell: 2 seconds; mode: peak. A stainless steel prove will be used. The result of the test will the force required to break the bond between the probe and the surface of the test sample. The force will be measured in “grams of tack”.
The peel adhesion data will be obtained using the following test method. The peel adhesion testing will be based on ASTM D3330-90. This will involve peel from a substrate at a 180° peel angle done with a constant rate of extension tensile tester. The substrate used will be Vitro-Skin™ N-19 (VS), an artificial skin substitute available from Innovative Measurement Solutions, Inc. that is designed to mimic human back skin. The VS may be conditioned prior to sue at 23° C. for about 16 hours in a chamber containing a solution consisting 70:30 by volume water:glycerol to maintain constant humidity. All testing will be done on the textured side of the VS. Immediately upon removal of the VS from the conditioning chamber, the VS will be attached using a double sided adhesive tape to the backing of a foam tape (3M 1777, 40 mil (1016 μm) thick) which will be attached to a steel plate to provide a stable testing surface. Testing will be done in a controlled environment at 23° C.±2° C. and 50%±3% relative humidity. A 1.0 cm width strip of the coated sheet will be allowed to dwell for 2 m prior to peel testing.
The free end of the coated strip will be doubled back so the angle of removal will be 180°. The removal peel rate will be determined and the force of adhesion will be presorted as grams per centimeter (g/cm).
A reservoir patch containing 0.86 gram of a formulation including a cationic salt of endoxifene as described in example 11 will be tested on 12 human subjects. The reservoir patch will have a skin-formulation contact area of 6 cm2. The patch will be applied to the breast nipple and the areola. The patch will be applied to a subject's skin for 72 h before removal. In some subjects, a second patch may be placed after 72 h on a different location on the breast for additional 72 h before removal of the second patch.
The mean plasma concentration of endoxifen following the patch application will be determined. The mean Area Under the Plasma Drug Concentration Curve (AUC) values or 0-72 h and 0-144 h will be determined and expressed as ng-h/mL.
