This application claims the benefit of U.S. Provisional Application No. 62/037,272 filed Aug. 14, 2014, which is incorporated herein by reference.


BACKGROUND
Surgical and non-surgical procedures for improving appearance have increased in prevalence as populations age and gain weight. Liposuction is a popular cosmetic surgery procedure and involves the surgical removal of fat deposits using suction and optionally assisted by solutions to assist in fat removal. Liposuction is a surgical procedure that removes fat through an incision in the skin through which a cannula is inserted. The cannula is connected to a suction source and the unwanted fat is aspirated through the cannula and discarded. Liposuction is performed under general or local anesthesia, depending on the amount and location of the fat to be removed. However, liposuction and other surgical methods of fat removal are associated with significant adverse events including temporary bruising, swelling, numbness, soreness and burning sensation, risk of infection, pigmentation changes, the formation of fat clots or blood clots which can migrate to the lungs and cause death, excessive fluid loss, which can lead to shock or fluid accumulation that must be drained, friction burns or other damage to the skin or nerves or perforation injury to the vital organs. Additionally, liposuction requires a recovery time of one to two weeks wherein the patient cannot work or perform certain daily activities. Moreover, because surgical procedures such as liposuction require local and occasionally general anesthesia, significant anesthesia-related risks are associated with surgical fat removal (including, e.g., loose and flabby skin) Furthermore, in certain situations liposuction and other drastic weight loss methods can be life threatening to the patient.
Accumulation of fat stores can occur unevenly in the body. For example, some persons may accumulate fat predominantly in the abdominal cavity while others predominately in the subcutaneous tissue. Gender differences may also be apparent with women accumulating fat in the thighs and lateral buttocks and males in the waist. Women may accumulate fatty deposits of the thighs, which have a rumpled or “peau-de-orange” appearance, resulting in a condition referred to as cellulite. Cellulite may be related to skin architecture which allows subdermal fat herniation, sometimes referred to as adipose papillae. Other factors that may be related to cellulite include altered and/or reduced connective tissue septae, vascular and lymph changes that lead to fluid accumulation, and inflammation. Fat tissue may also accumulate in the form of a fibrous fatty deposit known as a lipoma. Lipomas are tumors of fatty tissues, generally benign. If malignant, they are known as liposarcomas. Benign lipomas contain normal fat that is encapsulated within a fibrous sphere, thus often compressing the fat and causing it to feel more firm than surrounding fat. Many lipomas are asymptomatic and are removed for non-medical reasons. However, a significant number of them cause the patient pain or discomfort and they interfere with normal activity.

As used herein, the term “tetradecyl sulfate-like compound” refers to a compound of Formula I or Formula II, or salts, solvates, prodrugs, or esters thereof
As used herein, the term “coadministered,” refers to the administration of two or more therapeutic agents in a single formulation or separate formulations or routes of administration in any order for the purpose of treating the same health condition (e.g., a lipoma) in the same subject.
A “therapeutically effective amount,” as used herein, refers to a sufficient amount of an agent (e.g., sodium tetradecyl sulfate) or other compound being administered which will relieve to some extent one or more of the symptoms of the disease or condition being treated. The result can be reduction and/or alleviation of the signs, symptoms, or causes of a disease, or any other desired alteration of a biological system. For example, an “effective amount” for therapeutic uses is the amount of the composition including a compound as disclosed herein required to provide a clinically significant decrease in disease symptoms without undue adverse side effects. An appropriate “effective amount” in any individual case can be determined using techniques, such as a dose escalation study. The term “therapeutically effective amount” includes, for example, a prophylactically effective amount. An “effective amount” of a compound disclosed herein, is an amount effective to achieve a desired pharmacologic effect or therapeutic improvement without undue adverse side effects. It is to be understood that “an effect amount” or “a therapeutically effective amount” can vary from subject to subject, due to variation in metabolism of the compound of Formula I or Formula II, age, weight, general condition of the subject, the condition being treated, the severity of the condition being treated, and the judgment of the prescribing physician.
A “cosmetically effective amount” as used herein refers to the amount of a compound sufficient to improve the outward physical appearance of a subject. The outward physical appearance of a subject includes, for example, the reduction of fat deposition in certain regions of the body including, for example, the midsection of the body. “Cosmetically effective” as used herein, also refers to a sufficient amount of an agent (e.g., sodium tetradecyl sulfate) which will improve the cosmetic appearance at the localized site of treatment. A “cosmetically effective” amount of tetradecyl sulfate is an amount effective to achieve a cosmetically desirable improvement. It is to be understood that a “cosmetically effective” amount can vary from subject to subject, due to numerous factors including age, weight, general condition of the subject, the condition being treated, the severity of the condition being treated, and the judgment of the prescribing physician.
Bile Acid
Bile acids are steroid acids found predominantly in the bile of mammals. Bile acids are made in the liver by the cytochrome P450-mediated oxidation of cholesterol. They are conjugated with taurine or the amino acid glycine, or with a sulfate or a glucuronide, and are then stored in the gallbladder, which concentrates the salts by removing the water. In humans, the rate limiting step is the addition of a hydroxyl group on position 7 of the steroid nucleus by the enzyme cholesterol-7-alpha-hydroxylase. Upon eating a meal, the contents of the gallbladder are secreted into the intestine, where bile acids serve the purpose of emulsifying dietary fats. Bile acids serve other functions, including eliminating cholesterol from the body, driving the flow of bile to eliminate catabolites from the liver, emulsifying lipids and fat soluble vitamins in the intestine to form micelles that can be transported via the lacteal system, and aiding in the reduction of the bacteria flora found in the small intestine and biliary tract.




In humans, the most important bile acids are cholic acid, deoxycholic acid, and chenodeoxycholic acid. Deoxycholic acid is one of the secondary bile acids, which are metabolic byproducts of intestinal bacteria. The two primary bile acids secreted by the liver are cholic acid and chenodeoxycholic acid. Bacteria metabolize chenodeoxycholic acid into the secondary bile acid lithocholic acid, and they metabolize cholic acid into deoxycholic acid. Additional secondary bile acids include ursodeoxycholic acid. In the human body deoxycholic acid of Formula XVIII is used in the emulsification of fats for the absorption in the intestine.
In some embodiments, one or more of deoxycholic acid, cholic acid, chenodeoxycholic acid, and sodium deoxycholate is co-administered with a formulation described herein and the effective amount of sodium deoxycholate is about 0.01 to about 100 mg/day, e.g., about 1 mg/day to about 50 mg/day, about 0.01 mg/day to about 0.1 mg/day, about 0.05 mg/day to about 0.5 μg/day, about 50 mg/day to about 100 mg/day, about 5 mg/day to about 45 mg/day, about 0.75 mg/day to about 75 mg/day, about 25 mg/day to about 50 mg/day of bile acid, or any other dose of bile acid from about 0.01 mg/day to about 100 mg/day.
In some embodiments, in addition to treating a human with any of the compositions described herein, a physician or other authorized medical caregiver prescribes a liposuction procedure, or performs a liposuction procedure on the human to further reduce regional fat deposits.
In some embodiments, a liposuction procedure is performed on a human who has been administered a composition comprising a therapeutically effective amount of a compound of Formula I or Formula II, or a pharmaceutically or cosmetically acceptable salt, solvate, prodrug, or ester thereof. Without wishing to be bound by theory, administering any of the just-described sustained release pharmaceutical compositions to a subject prior to liposuction is likely to increase the efficacy of the liposuction procedure.
Embodiments of the composition are formulated for administration by any suitable method, for example, as described in Remington: The Science And Practice Of Pharmacy (21st ed., Lippincott Williams & Wilkins) Exemplary routes of administration include, but are not limited to parenteral, oral, subcutaneous, topical, intramuscular, transdermal, transmucosal, sublingual, intranasal, transvascular, subcutaneous, orbital, or respiratory. In some embodiments, the composition is formulated for injection of an area at which treatment is desired, for example, in a regional fat deposit.
Any suitable pharmaceutically acceptable excipient appropriate for a particular route of administration can be used. In some embodiments, the pharmaceutically acceptable excipient is disodium phosphate. In some embodiments, the pharmaceutically acceptable excipient is dihydrogen phosphate. In some embodiments, the pharmaceutically acceptable excipient is sodium hydroxide. The formulation may also contain any suitable pharmaceutically acceptable carrier. Examples of pharmaceutically acceptable carriers include, but are not limited to, buffers, saline, or other aqueous media. In certain embodiments, the formulation has a pH of from about 6 to 10. In some embodiments, the formulation has a pH of about 7 to 8. The compounds of the invention are preferably soluble in the carrier which is employed for their administration (e.g., subcutaneous). Alternatively, a suspension of the active compound or compounds (e.g., a suspension of crystalline microparticles) in a suitable carrier is employed. Some embodiments comprise any suitable lipophilic carrier, for example, modified oils (e.g., Cremophor® BASF, Germany), soybean oil, propylene glycol, polyethylene glycol, derivatized polyethers, combinations thereof, and the like. Some embodiments comprise a microparticulate and/or nanoparticulate carrier for at least one of the beta-2 receptor agonists and/or glucocorticosteroids, as discussed in greater detail below. Some embodiments comprise one or more sustained or controlled release carriers or agents, for example, polymer microspheres. Some embodiments comprise excipients suitable for stable suspensions for micronized particles of tetradecyl sulfate.
Injectable formulations are administered using any method known in the art, for example, using a single needle, multiple needles, and/or using a needleless injection device. In some embodiments, a tissue loading dose of the active ingredients formulated in a suitable carrier delivered by injection. In some embodiments, delivery comprises single needle injection. In some embodiments, delivery comprises injection using a multi-needle array, which, in some embodiments, provides a wide dispersion of the formulation in the target tissue. In some embodiments, formulations are injected in a manner that allows dispersal into the appropriate layer of subcutaneous fat in areas where regional fat.
The interval between administration of the compound of Formula I or Formula II, glucocorticosteroid, and/or bile acid can be an interval from about 5 minutes to about 1 month, e.g., 30 minutes, 1 hour, 6 hours, 12 hours, one day, 2 day, 3 days, 4 days, 5 days, 6 days, 7 days, 10 days, 2 weeks, 3 weeks, or any other time interval from about 5 minutes to about 1 month.
Some embodiments of the formulations described herein comprise one or more sustained or controlled release agents for providing a sustained or controlled release of a compound of Formula II, a glucocorticosteroid, and deoxycholic acid or pharmaceutical or cosmetically acceptable salts, solvates, prodrugs, or esters thereof. In some embodiments formulations comprise the compound of Formula II, and at least one of beta-2 agonist, glucocorticosteroid, and deoxycholic acid. In some embodiments, biocompatible, biodegradable, sustained, or controlled release formulations provide local tissue activity. Sustained release can be over a period from about 12 hours to about 12 months, e.g., one day, 3 days, 7 days, 10 days, 1 month, 45 days, 2 months, 3 months, 4 months, 6 months, 8 months, 9 months, 10 months, 11 months, or any other time period from about 12 hours to about 12 months. Suitable sustained or controlled release agents or carriers include polymers, macromolecules, active ingredient conjugates, hydrogels, contaminations thereof, and the like. Some embodiments of the sustained release carrier target fat, for example, liposomes. Preferably, the sustained release materials are selected to facilitate delivery of a substantially equal amount of the active substance per unit time. Several rounds of injections of the sustained release formulation can be made over time to treat a single area. In some embodiments, sustained release results from formulating the compound of Formula II, as a suspension of crystalline drug microparticles.
In some embodiments, the sustained release agent comprises a polymer, for example, polylactides, polyglycolides, poly(lactide glycolides) polylactic acids, polyglycolic acids, polyanhydrides, polyorthoesters, polyetheresters, polycaprolactones, polyesteramides, polycarbonates, polycyanoacrylates, polyurethanes, polyacrylates, and blends, mixtures, or copolymers of the above, which are used to encapsulate, bind, or conjugate with the active ingredients(s) (e.g., beta adrenergic agonists and/or glucocorticosteroids). Some preferred embodiments of sustained release polymers comprise polyethylene glycol groups to which one or more of the active ingredients are conjugated. In some preferred embodiments, the sustained release agent comprises poly(lactide glycolide) (PLGA, poly(lactic-co-glycolic acid)) copolymer of Formula XIX.




Some embodiments of the sustained release agent comprise one or more hydrogels, including modified alginates. Examples of suitable modified alginates include those disclosed in WO 98/12228which is incorporated by reference for purposes of that disclosure. Some embodiments of the sustained release agent comprise an albumin-based nanoparticle carrier or excipient.
In some embodiments, a formulation comprising a prepolymer solution is injected into the target tissue site, where it is then polymerized (e.g., by photopolymerization) or solidified (e.g., by using temperature sensitive gelling materials) in vivo.
In some embodiments, the controlled release materials have release characteristics designed for the particular application of tissue reduction. In some embodiments, the sustained release or controlled release agent is formed into microparticles, such as microspheres, which are formulated as an injectable solution and/or gel. In some embodiments, the microparticles range in size from about 10 μm to about 100 μm in diameter (e.g., about 15 μm, 20 μm, 25 μm, 30 μm, 40 μm, 50 μm, 60 μm, 70 μm, 80 μm, 90 μm or any other diameter from about 10 μm to about 100 μm). In some embodiments, the microparticles are uniform in size. In other embodiments, the microparticles vary in size by about 10% to about 300%, e.g., 30%, 40%, 50%, 70%, 80%, 90%, 120%, 150%, 170%, 190%, 200%, 225%, 250%, 275%, or by any other percentage variation in size from about 10% to about 300%. In some embodiments, formulations comprising alginates and/or poly(lactide-co-glycolide)s of Formula XIX are provided as an injectable gel or processed into microspheres. In other embodiments, the beta-2 agonist or a corticosteroid (or other compounds for reducing beta adrenergic receptor desensitization) are formed as crystalline microparticles. Other examples of suitable injectable biodegradable, biocompatible materials suitable for microparticle formation include chitosan, dextran, hydroxyapatite, and silicon.
Microspheres and/or microparticles are formed using any method, including by solvate evaporation and/or emulsion polymerization. In some embodiments, the microspheres have average diameters of from about 5 μm to about 60 μm, preferably, about 20 μm. In some embodiments, PLGA is manufactured with varying ratios of lactide to glycolide depending on the desired rate of release of the active ingredient(s). Because the rate of degradation of this copolymer is proportional to its crystallinity and the proportion of glycolide in the formulation, non-racemic mixtures of the lactide and/or glycolide increase crystallinity and slow the rate of degradation. Higher proportions of glycolide increase the rate of degradation. In some embodiments, a ratio of about 65%-75% lactide to about 25%-35% glycolide provides active ingredients released over from about 2 weeks to about 45 days. In other embodiments, the ratio of lactide to glycolide is from about 0:100 to about 100:0, thereby providing other release rates.
Some embodiments of the microspheres or microparticles comprise hollow and/or porous interiors. In some embodiments, the microspheres comprise a solid or porous outer shell.
The microspheres comprising the active ingredient(s) are suspended in about 10 ml to about 20 ml of an appropriate physiologically acceptable liquid carrier. In some embodiments using separate microspheres of the active ingredients, the microspheres are mixed together in the liquid carrier. In other embodiments, each type of microsphere is separately mixed with a liquid carrier. In some embodiments, the microsphere suspension is then injected subcutaneously just below the dermis in 1.0 ml aliquots to cover about 2.0 cm2 area per ml of the microsphere suspension, for example, for the treatment of cellulite. In some embodiments, about 10 to about 20 injections are administered to cover an area of from about 20 cm2 to about 40 cm2. Larger and/or smaller areas are treated in various embodiments. Alternatively, in some embodiments, bolus injections of 1.0 ml to 10.0 ml are injected into fat accumulations, such as the submental regions, lateral hips, and buttocks. Alternatively, injections as described above are made separately and sequentially in the same locations using two microsphere formulations encapsulating each active ingredient.
In some embodiments, needle-less injection is used to administer the microparticulate formulations as suspensions or as powdered loaded microparticles, i.e., without a liquid carrier.
PLGA microspheres encapsulate hydrophobic compounds more readily than hydrophilic compounds. To increase loading of hydrophilic active ingredients, in some embodiments, the microspheres are modified with polyethylene glycol units, as discussed above. Microspheres of certain sizes are substantially not absorbed into the blood or removed by lymph, thereby providing localized release of the active ingredient(s) within a target region. For example, in some embodiments, the microspheres are about 20 μm to about 200 μm in diameter, e.g., about 30 μm to about 175 μm, about 50 μm to about 150 μm, about 75 μm to about 125 μm, or any other diameter from about 20 μm to about 200 μm. The size of the microsphere also affects the release profile of the active ingredient(s) in the tissue. In general, larger microspheres provide a longer and more uniform release profile. Accordingly, in some embodiments, the average particle size in the formulation will be selected based on the desired release duration.
In an exemplary embodiment, a sustained release formulation comprises about 0.5 mg to about 7.5 mg (e.g., about 0.7 mg, 1 mg, 1.5 mg, 2.0 mg, 2.5 mg, 3 mg, 3.5 mg, 4 mg, 4.5 mg, 5 mg, 5.5 mg, 6 mg, 6.5 mg, 7 mg, or any other amount from about 0.5 mg to about 7.5 mg) of a compound of Formula I or Formula II, optionally about 1.5 mg to about 7.5 mg (e.g., about 2 mg, 2.5 mg, 3 mg, 3.5 mg, 4 mg, 4.5 mg, 5 mg, 5.5 mg, 6 mg, 6.5 mg, 7 mg, or any other amount from about 1.5 mg to about 7.5 mg) of dexamethasone, fluticasone, and/or budesonide, and also optionally about 1.5 mg to about 7.5 mg (e.g., about 2 mg, 2.5 mg, 3 mg, 3.5 mg, 4 mg, 4.5 mg, 5 mg, 5.5 mg, 6 mg, 6.5 mg, 7 mg, or any other amount from about 1.5 mg to about 7.5 mg) of deoxycholic acid or a pharmaceutically or cosmetically acceptable salt, solvate, prodrug, or ester thereof encapsulated in about 100 milligrams of polylactide glycolide (PLGA) copolymer microspheres at a ratio of about 70 lactide:30 glycolide. The amount of each active ingredient in the sustained release formulation depends on the period of controlled/sustained release required (about 3 days to about 12 months, e.g., 4 days, 5 days, 7 days, 10 days, 1 month, 45 days, 2 months, 3 months, 6 months, 8 months, 9 months, or any other release period from about 3 days to about 12 months).
In some embodiments, the subject to be treated is provided a non-sustained release formulation. In some embodiments, the non-sustained release formulation, after a single dose, provides activity for a duration from about 4 hours to about 24 hours, e.g., about 6 hours, 8 hours, 10 hours, 12 hours, 16 hours, 18 hours, 21 hours, or any other duration from about four hours to about 24 hours.
While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the disclosure. The formulations, methods, and kits described herein may be embodied in a variety of other forms. Furthermore, various omissions, substitutions and changes in the form of the formulations, methods, and kits described herein may be made without departing from the spirit of this disclosure. The accompanying claims and their equivalents are intended to cover such forms or modifications.

Example 2
Treatment of Fat Deposits with Compositions Comprising Sodium Tetradecyl Sulfate and Sodium Deoxycholate
Primary human adipocytes will be incubated with varying concentrations of sodium tetradecyl sulfate and synthetic sodium deoxycholate synthesized using 9-HAD as starting material or bovine-derived sodium deoxycholate obtained from Sigma as described below.
Materials
Adipocytes (Zen-Bio cat #SA-1096), 96 well plates (US Scientific cat #cellstar no. 655180), Serum-free RPMI medium (Mediatech cat #17-105-CV), sodium tetradecyl sulfate, Sodium deoxycholate (DC) (Sigma cat #D6750), Synthetic Sodium glycodeoxycholate, PBS, MTS assay kit (Promega cat #G3580)
Adipocytes will arrive differentiated and at a density of 13,000 cells per well in a 96 well plate. Two plates will be received and each treated with the same samples. Cells will be incubated for 24 hours at 37° C. with 5% CO2. A 1% stock solution of each bile acid (synthetic and non-synthetic DCA) will be made by dissolving 20 mg into 2 mL media (serum-free). Using the 1% stock solution, the following 11 solutions are prepared by dilution: 0.005%, 0.01%, 0.015%, 0.02%, 0.025%, 0.03%, 0.035%, 0.04%, 0.05%, 0.06%, and 0.1%, as well as 0% (media only).
Cells will be washed 2 times with 150 μL of room temperature lx PBS (phosphate buffered saline). Media and then PBS will be removed from the wells in a 96 well plate by turning the plate upside down and decanting the liquid into a container. After the last PBS wash, 80 μL of sample will be added per well. Each concentration of a specific bile acid will be added to 8 wells and will be incubated for 1 hour at 37° C. with 5% CO2. Plates will be removed from incubator and solution decanted. A 100 μL solution of will be diluted (40 μL in 1 mL of RPMI) MTS reagent (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl-)-2H-tetrazolium, inner salt) will be added directly to each well. Plates will be incubated at 37° C. with 5% CO2 until control (no bile acid) wells change color to orange-brown and then loaded onto a spectrophotometer that analyzes 96 well plates. Samples will be run at 490 nm wavelength setting.
Example 3
Phase III Clinical Study
A multicenter, phase III, randomized, double-blind, placebo-controlled, parallel-group study will be used to evaluate the efficacy and safety of sodium tetradecyl sulfate administered at fixed doses of 0.5% W/V and 1.0% WN. The study will be divided into a screening period (week 1-8 to baseline; visit I), followed by a 12-week treatment period (visits 2-5) and a 1.2-week efficacy and safety follow-up period (visits 6 and 7).
Inclusion and Exclusion Criteria
Men and women aged 18-65 years are eligible to participate if they present with moderate or severe submental fat (“SMF”) [grade 2 or 3 on the 5-point Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)] and express dissatisfaction with the appearance of their submental area [Subject Self-Rating Scale (SSRS) score 0-3] at visit 2. Patients will agree to undergo clinical evaluations and laboratory tests and to maintain stable body weight, diet and exercise practices during the study. Women of reproductive age will be required not to be pregnant or lactating and to practice birth control during the study. The principal exclusion criteria will be: previous intervention to treat SMF; anatomical features or previous trauma liable to interfere with SMF evaluation or result in an aesthetically unacceptable outcome after treatment; evidence of any cause of submental enlargement other than SMF; and any medical condition likely to affect safety or efficacy assessments or the patient's ability to undergo study procedures or provide informed consent. Patients with a body mass index (BMI) >30 kg m−2, those undergoing or considering a weight-reduction program, and patients with a history of sensitivity to any components of the study material or topical or local anesthetics will also be excluded.
Randomization
Patients will be randomized (1:1:1) at visit 2, after completion of baseline evaluations, through allocation of a unique randomization number using a computerized web/voice-response system. Sodium tetradecyl sulfate and placebo treatment kits will have an identical appearance and carry a blinded label with a random kit number; these will be assigned to patients using the computerized system.
Interventions
All randomized patients will have at least one treatment session, with a maximum of four sessions, separated by 28±5 day intervals (visits 2-5), Patients will receive up to 10 mL of the study drug per treatment session, and the number of sessions will be dependent on the amount of remaining SMF and each patient's satisfaction with the appearance of their face and chin. Injections will be administered subcutaneously directly into the pre-platysmal SMF at a volume of 0.2 ml, per injection and spaced approximately 1 cm apart using a grid to provide even coverage. Topical anesthesia will be provided, if needed. Premature treatment discontinuation could occur owing to adverse events (AEs), early therapeutic success or at the patient's request. The treatment area will be evaluated 7±3 days after each treatment and concomitant medication use was reported, Patients will attend two follow-up visits (visits 6 and) 4 weeks (±5 days) and 12 weeks (±7 days) after the final treatment session.
Efficacy Outcome Measures
Efficacy endpoints will be evaluated at visit 7 (12 weeks after final treatment). There will be two co-primary efficacy endpoints: the proportion of treatment responders, i.e. with a reduction in SMF of ≧1 point on the 5-point CR-SMFRS relative to baseline, and the proportion of patients satisfied with their appearance in association with their face and chin with a score of ≧4 on the 7-point SSRS rating scale). To confirm the primary endpoint results, sensitivity analyses will be conducted on the secondary parameters of change from baseline in CR-SMFRS and SSRS scores, and changes in caliper measurements of SMF thickness, by treatment session. The effect of treatment on skin laxity (Skin Laxity Rating Scale, SLRS) will also be evaluated, and patient-reported outcomes will be assessed using the Patient-Reported Submental Fat Rating Scale (PR-SMFRS) and Patient-Reported Submental Impact Scale (PR-SMFIS). Additional patient-reported instruments will also be used.
Safety Outcome Measures
Adverse effects (AE) will be evaluated at each visit and approximately 7 days after each treatment session, and will be characterized descriptively by the day on which they started and stopped, and by severity and intensity. Treatment-emergent AEs will be defined as those with onset or exacerbation after the first treatment dose. Changes from baseline in clinical laboratory parameters and other tests, and variations in vital signs, body temperature and body weight, will also be measured.
Statistical Methodology
Using 80% of the effect size observed in two previous placebo-controlled and a 10% dropout rate per treatment group with a Pearson chi-square test for two proportions (two-sided test with α=0.025), a conservatively rounded sample size of 120 patients per treatment group be used to guarantee a power of 90%.
The efficacy analyses will be based on the intention-to-treat population (all randomized patients who had at least one efficacy assessment at baseline), with missing values at visit 7 imputed using last observation carried forward. The null hypothesis for the treatment comparisons is that there is no difference between each dose of sodium tetradecyl sulfate and placebo for the two co-primary efficacy endpoints. Comparisons of the two sodium tetradecyl sulfate dose groups with placebo will be made via odds ratios from binary logistic regression. An adjustment for multiplicity will be performed. Because there will be two co-primary endpoints, the null hypotheses for both variables will be rejected at the same significance level (α=0.05). This will be accounted for by using the larger of the two P-values in the Bonferroni-Holm procedure.
For the secondary endpoints, changes from baseline in CR-SMFRS and caliper scores will be analyzed using a mixed-models repeated-measures analysis. Changes from baseline in SSRS scores will be analyzed by an analysis of variance (ANOVA). PR-SMFRS improvements of ≧1 point are analyzed by binary logistic regression. Changes from baseline in SLRS scores will be recorded in frequency tables and Pearson's chi-square test will be applied to compare each sodium tetradecyl sulfate group with placebo. Descriptive statistics will be calculated for PR-SMFIS scores, with the change from baseline analyzed by a post hoc Fisher's least-square difference test for continuous variables, only if ANOVA shows an overall treatment effect. Statistical summaries for AEs will be based on treatment-emergent AEs in the safety population (all patients who received at least one treatment with study drug). The numbers of AEs and patients presenting with each AE will be categorized according to association with treatment, study withdrawal, death, severity, intensity, system organ class, and preferred term.
