FDA Orphan Designation for Biotie Therapies Liver Drug
FDA has granted Biotie Therapies an orphan drug designation for its BTT1023 drug candidate for treating primary sclerosing cholangitis (PSC), which is a chronic and progressive fibrotic liver disease for which there are currently no FDA-approved treatments. The company says BTT1023 is a fully human monoclonal antibody targeting Vascular Adhesion Protein -1, and it is currently being studied for PSC in a Phase 2a study (BUTEO study). The two-stage study design includes a pre-planned interim analysis, it says, and based on current enrollment estimates, it expects the analysis will be performed in the first half of 2017.
