We are developing an extended-release formulation of dipraglurant as a novel orally available mGlu5 NAM for the treatment of blepharospasm. There are many types of dystonia affecting up to 300,000 people in the United States. Blepharospasm is characterized by involuntary muscle contractions and spasms of the eyelid muscles resulting in sustained eyelid closure causing substantial visual disturbance or functional blindness.
Blepharospasm affects approximately 50,000 people in the United States with 2,000 new patients being diagnosed annually. We are conducting an exploratory placebo-controlled Phase 2 clinical trial in blepharospasm patients, using the current immediate release formulation of dipraglurant. Enrollment is completed and we expect to report topline results in the second quarter of 2022.
Subject to regulatory approval, we believe that dipraglurant may offer an innovative and differentiated treatment approach for multiple types of dystonia and present a significant commercial opportunity.
