Multiple Sclerosis Clinical Trial
Official title:
A Phase 2, Double-blind, Randomized, Placebo-controlled, Four-arm, Multicenter, Dose-finding Study to Assess the Safety and Efficacy of Three Dose Levels of AVP-923 (Dextromethorphan/Quinidine) in the Treatment of Central Neuropathic Pain in Patients With Multiple Sclerosis
The objectives of the study are to evaluate the safety, tolerability, and efficacy of 3 doses of AVP-923 capsules in the treatment of central neuropathic pain in participants with multiple sclerosis.
The objectives of the study are to evaluate the safety, tolerability, and efficacy of 3 doses of AVP-923 (dextromethorphan [DM]/quinidine [Q]) capsules containing either 45 mg DM and 10 mg Q (AVP-923-45) or 30 mg DM and 10 mg Q (AVP-923-30) or 20 mg DM and 10 mg Q (AVP-923-20) compared to placebo, for the treatment of central neuropathic pain in a population of participants with multiple sclerosis (MS) over a 12-week period. The MS participant population enrolled includes participants with relapsing-remitting multiple sclerosis (RRMS) and participants with secondary progressive multiple sclerosis (SPMS). ;
