MR-201

August 21st , 2019 PRINCETON, N.J., August 21st , 2019 -- SHINKEI Therapeutics, a clinical stage pharmaceutical company focused on the development of drugs for the treatment of Central Nervous System (CNS) disorders, today announced the filing of an Investigational New Drug ("IND") application with the U.S. Food and Drug Administration ("FDA") of MR-201, a novel dosage form for the treatment of Pseudobulbar Affect (PBA). There are limited treatment options available for PBA which affects almost 1.8 million patients in USA. The successful filing of this IND is a key milestone. This submission follows our PIND meeting feedback, preliminary animal studies and a pilot human pharmacokinetic study. The clinical development program for MR-201 will commence with a Phase I study in healthy volunteers. The goals of the study will be to assess the tolerability and steady state pharmacokinetics of MR-201. SHINKEI seeks to leverage existing clinical and nonclinical data in conjunction with sponsor-initiated studies, such as this Phase I study and the previously completed pilot study, to accelerate development and approval of MR-201 via the 505(b)(2) pathway.
