Phase 2 Dermatomyositis Trial (Ongoing)

Corbus has completed enrollment in the double-blind phase of its study of anabasum for the treatment of dermatomyositis. The study was a Phase 2, double-blind, randomized, placebo-controlled study investigating the safety, tolerability and efficacy of anabasum in patients with dermatomyositis.

Study participants were screened for up to 28 days to ensure they met study entry criteria. Following the initial screening, participants were provided with either a dose of anabasum or placebo for once a day dosing for 28 days. On the 29th day, participants were transitioned to twice a day dosing for 56 days. The total treatment period was 84 days. After the treatment period, participants were followed for an additional 28 days.

Study participants who complete the first portion of the study have the option of enrolling in a 12-month, open-label extension to receive anabasum twice a day.
