Official title
The ASCEND Study: A Phase III, Multicenter, Double Blinded Vehicle Controlled Study of TMB-001 - With a Parallel Optional Maximal Use Arm - in the Treatment of RXLI (X-linked) or ARCI Ichthyosis in Subjects Aged ≥6 Years
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a randomized, double-blind and vehicle-controlled Phase III study to evaluate the safety and efficacy of topical TMB-001 0.05% ointment for the treatment of congenital ichthyosis (CI) in subjects with either the RXLI or ARCI subtypes. In addition, a subset of preselected centers will recruit subjects in parallel with either the RXLI or ARCI subtypes for enrollment into an Optional Maximal Use arm for evaluation of the systemic exposure and safety of topical TMB-001 0.05% ointment for the treatment of CI. The Phase III Study is designed in three periods: \- Period 1 - Induction (3 weeks): At the beginning of the 3-week Induction Period, eligible subjects will be randomized (2:1 ratio) to either TMB-001 0.05% once-a-day (QD) or Vehicle QD treatment, with use of mandatory standardized bland emollient (Cetaphil™) provided by the Sponsor. \- Period 2 - Treatment (9 weeks): The dosing frequency in the 9-week treatment period will be increased in each treatment group to TMB-001 0.05% BID or Vehicle BID. Mandatory bland emollient will be discontinued. \- Period 3 - Maintenance (12 weeks): At Week 12, eligible subjects in the TMB-001 treatment group will be randomized (1:1 ratio) to an open-label treatment with TMB-001 0.05% BID or TMB-001 0.05% QD. To be eligible, subjects must have achieved a ≥1-point reduction in IGA score from Baseline. Subjects with less than a 1-point reduction in IGA score from Baseline will be discontinued from the study. Vehicle-treated subjects who achieved \<1-point reduction in IGA score from Baseline are eligible to cross over to the TMB-001 0.05% BID treatment group. Subjects with a ≥1-point reduction in IGA score from Baseline on vehicle will be discontinued from the study. Subjects at the end of the study or subjects discontinued from the study at any time will be followed-up for additional 2 weeks for AEs.
