Details and patient eligibility

About

Phase 2 clinical trial conducted in 2 parts: Part 1 - Pharmacokinetics and Part 2 - Randomized and Placebo Controlled (subject and clinical assessors will be blinded). Study Product will be applied to AD BID days 1-28. There will be weekly visits from Baseline (day 1) through Day 29. There is a final follow up visit 2 weeks after.

Full description

Group 1 is an open-label safety cohort to determine the PK profile of the active study drug, BMX-010 ointment. At least 3 and up to 12 subjects will be enrolled to analyze the safety and pharmacokinetics of BMX-010 ointment. If a subject cannot complete the required PK blood draws, another subject will be enrolled to ensure at least 3 subjects complete the PK blood draws. Subjects will not be randomized and all subjects in this group will be dispensed BMX-010. Dispensing information will be provided by IWRS. Study drug will be administered in clinic on Day 1 and also Day 8 (the first study drug application of the day) in order to obtain pre-dose PK blood draws. Once a minimum of 3 subjects complete all of the PK blood draws (through Day 8) and the data is analyzed, the Clinical Safety Committee (CSC) will review and determine if enrollment to Group 2 can begin.

Enrollment of subjects into Group 2 will not begin until the PK and safety data from a minimum of three subjects enrolled in Group 1 is obtained and analyzed, and proceeding with Group 2 has been approved by the sponsor.

Once enrollment in Group 2 begins, the subjects will be randomized into Arm A, B, or C.

Group 2 is a randomized, partially blinded (where neither the subjects nor the appropriate clinical center staff are told which treatment or intervention participants are receiving), placebo-controlled cohort designed to further test the safety and efficacy of BMX-010 ointment vs. placebo. Up to approximately 216 adult subjects with AD will be enrolled. At the baseline visit, subjects will be randomized to receive BMX-010 (0.5% or 0.1%) or placebo in a 1:1:1 ratio, by a permuted block randomization schema.

Enrollment: 103 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

• vIGA-AD score ≥ 2 (greater than or equal to 2) at screening and Day 1.
• Candidate for topical treatment of AD;
• Subjects must be willing to apply an emollient of their choice during study.
• Females of child-bearing potential must have a negative urine pregnancy test at screening and on the day of the first drug administration;
• Females of child-bearing potential must be willing to use 2 methods of contraception deemed adequate through the trial and for 1 month thereafter to be eligible for, and continue participation in, the study.
• Ability to complete the study in compliance with the protocol, including agreement in writing to apply IP only to the assigned areas.
• Ability to understand and provide written informed consent.

Exclusion criteria

• Subjects with AD only located on the hands and feet.
• Subjects with clinically infected AD.
• Subjects for which systemic pharmacotherapy or phototherapy for the treatment of AD is indicated or required.
• Treatment with systemic retinoids, corticosteroids, immunomodulators or immunosuppressive agents (e.g., methotrexate, cyclosporine), cytotoxic agents, interferon, upadacitinib, abrocitinib, or baricitinib within 4 weeks of the Baseline visit or anticipated need for any of these therapies during the study period.
• Treatment with topical corticosteroids, crisaborole, ruxolitinib, Vitamin D analogs, keratolytics, coal tar, calcineurin inhibitors, antihistamines or any other therapeutic agents besides bland emollients within 2 weeks of the Baseline visit or anticipated need for any of these.
• Treatment with a biological agent (such as a monoclonal antibody) within a period of time of 12 weeks or 5 half-lives (whichever is longer) prior to Day 1.
• Subject has used systemic antibiotics within 2 weeks or topical antibiotics within 1 week prior to Day 1. Of note, subjects with herpes labialis or genitalis and use of antivirals for these diseases are allowed.
• Subject has used dupilumab within 26 weeks prior to Day 1.
• Subject has used doxepin within 1 week prior to Day 1.
• Subject has used hydroxyzine or diphenhydramine within 1 week prior to Day 1.
• Subject has used topical products containing urea within 1 week prior to Day 1.
• Subject has used medical devices, and bleach baths within 2 weeks prior to Day 1.
• Subject has had excessive sun exposure, is planning a trip to a sunny climate, or has used tanning booths within 4 weeks prior to Day 1 or is not willing to minimize natural and artificial sunlight exposure during the study. Use of sunscreen products (except on treated lesions) and protective apparel are recommended when sun exposure cannot be avoided.
• Subject has received an intravenous immunoglobulin (IVIg) therapy within 12 weeks prior to Day 1.
• AD triggered by an unavoidable environmental allergen or irritant.
• Contact dermatitis or drug-induced skin reactions.
• Concomitant skin disease that could confound clinical evaluations or increase risk to the subject.
• Systemic or skin infection requiring antimicrobial therapy within 14 days prior to Baseline.
• Systemic chemotherapy or radiotherapy within 4 weeks of the Baseline Visit.

• Pregnancy, planned pregnancy, lactation, or inadequate contraception as judged by the investigator.
• Active drug or alcohol dependence.
• Significant acute or chronic medical, neurological, or psychiatric illness that, in the judgment of the investigator, could compromise subject safety, limit the subject's ability to complete the study, and/or compromise the objectives of the study; clinically significant renal or hepatic insufficiency.
• History of malignancy, unless clinically cured for more than 5 years prior to Baseline. This exclusion does not apply to basal and squamous cell carcinomas of skin and carcinoma in situ of the cervix if they have been adequately treated and are clinically judged to be cured.
