This is a Phase 2b double-blind, randomized, placebo-controlled parallel-group study evaluating the safety and efficacy of arimoclomol (400 mg t.i.d.) compared to placebo. A safety lead-in phase will be employed to ensure the safety of all study volunteers.
Tier I (Safety Lead-in): During the enrollment period for the safety lead-in phase, 24 volunteers meeting inclusion/exclusion criteria will be randomized at 4 investigative sites. These volunteers will have weekly visits during the first 4 weeks after starting treatment. Pharmacokinetics (PK) will be performed at various timepoints throughout these 4 weeks. After the initial 4 weeks of treatment, visits will continue at 4-week intervals up to Week 36, subsequently visits will occur every 8 weeks up to Week 68. A final visit will occur at Week 72. There will be a 28-day post study medication Follow-Up Telephone Call to assess medical status and adverse events.
Tier II: After the Tier I volunteers finish 4 weeks of treatment, their data will be reviewed by the IDMC and, if no serious safety issues are identified, the recommendation will be made to start the second enrollment period (Tier II). During Tier II enrollment, volunteers recruited from approximately 30 to 40 centers in the US and Canada will be randomized. After screening and randomization, volunteers will be followed every 4 weeks for 9 months. Subsequently visits will occur every 8 weeks up to Week 68, with interim Follow-Up Telephone Calls at Weeks 16, 24, and 32 and a final visit at Week 72. A Week 76 Follow-Up Telephone Call to assess medical status and adverse events will occur at 28 days post last dose of study medication.
