Clinical Trial Summary

Study A083-02 is a multi-center, Phase 2 study to evaluate the safety, tolerability, pharmacodynamics (PD), efficacy, and pharmacokinetics (PK) of locally-acting ACE-083 in patients with Facioscapulohumeral muscular dystrophy (FSHD) to be conducted in two parts. Part 1 is open-label, dose-escalation and Part 2 is randomized, double-blind, and placebo-controlled.


Description:

Part 1 (dose escalation, open-label) Part 1 will consist of up to 6 cohorts of patients and will evaluate multiple ascending dose levels of ACE-083 administered unilaterally or bilaterally to either the tibialis anterior (TA) or biceps brachii (BB) muscle(s). Patients in each cohort will be enrolled in a 4-week screening period before beginning treatment. A Safety Review Team (SRT) will meet to review data for each cohort when at least 4 patients within a cohort have completed their Day 43 visit prior to dose escalation of the next cohort. Study duration for Part 1 for each patient will be approximately 24 weeks, including a 4-week screening period, a 12-week treatment period, and an 8-week follow-up period after the last dose. Part 2 (randomized, double-blind, placebo-controlled, with open-label extension) Prior to the initiation of Part 2, a review of safety and efficacy data from Part 1 will be conducted to determine whether cohorts for one or both muscles will be pursued in Part 2, as well as the recommended dose level for each muscle. A total of up to 56 new patients (28 patients per muscle) may be enrolled and randomized (1:1) to receive either ACE-083 (n=14/muscle) or placebo (n=14/muscle) bilaterally to either the TA or BB muscles (but not both). Patients will receive blinded study drug once every three weeks for approximately 6 months (9 doses). Patients who complete the double-blind treatment period will immediately roll over to open-label treatment with ACE-083, receiving the same dose of active drug, bilaterally in either the TA or BB muscle, once every three weeks for approximately 6 months (8 doses). In Part 2, the SRT will periodically review blinded safety data for each muscle treated. Study duration for Part 2 for each patient will be approximately 15 months, including a 1-month screening period, a 12-month treatment period (6-month double-blind, placebo-controlled and a 6-month open-label extension), and a 2-month follow-up period after the last dose

The FSHD-HI questionnaire was designed to measure both overall FSHD health-related quality-of-life and 14 separate subdomains designed and based on patient interviews to measure total FSHD health-related quality-of-life, including both motor impairment and the social and emotional impact of FSHD. The 116 questions are combined into a total score, the score is transformed onto a percentage scale; with a range of 0-100, with 100 representing maximal disability, and lower scores representing decreasing disability, 0 representing no disability. The mean and standard deviation for baseline and day 190 are reported as is the absolute change from baseline to Day 190 during the randomized controlled portion of Part 2.
