McEnany, Catalyst’s Chief Executive Officer. “We believe we have a clearly defined development and regulatory pathway for Firdapse in the treatment of LEMS and remain focused on our goal of improving access to treatments for patients with this significant unmet need.”

“Based on the positive results seen in our previous Phase 3 study, we look forward to continuing to investigate Firdapse for the treatment of LEMS,” said Gary Ingenito, M.D., Ph.D., Chief Medical Officer of Catalyst. “We are grateful to the patients and families, as well as their physicians, who have participated in our expanded access program and are participating in this second Phase 3 study.” (Original Source)
