Detailed Description
This study will consist of a screening period, double-blind (DB) treatment period, open-label (OL) treatment period, and safety follow-up period. During the DB treatment period, subjects will receive 5 total dose administrations of study drug (investigational product - IP or placebo) once every 3 weeks (Q3W) for a coverage of 15 weeks. After completing the DB treatment period, subjects may elect to enroll in an OL treatment period. In the OL treatment period, subjects will receive a dose of IP Q3W for 11 administrations for a coverage of 33 weeks, resulting in a combined total coverage of up to 48 weeks.
Subjects who do not elect to continue treatment in the OL dosing period will undergo an End of Treatment (EOT)-DB visit at Week 15 (Day 105), a Safety Follow-up Call at Week 21 (Day 147), and an End of Study (EOS) visit at Week 27. Eligible subjects who continue treatment in the OL treatment period will receive CM-101 at either a 10 mg/kg or 20 mg/kg dose commencing at Week 15 (OL Treatment 1), and the subjects will undergo an EOT-OL visit at Week 48 (Day 336), a Safety Follow-up Call at Week 54 (Day 378), and an EOS visit at Week 60 (Day 420).
