Principia Biopharma Reports Positive PRN1008 Phase 2 Top-Line Results and Initiates Phase 3 Pemphigus Program

Principia Biopharma (Nasdaq:PRNB), a clinical-stage biopharmaceutical company dedicated to bringing transformative oral therapies to patients with significant unmet medical needs in immunology and oncology, today announced positive top-line data from the completed open-label Phase 2 trial of PRN1008 in patients with pemphigus (including both pemphigus vulgaris (PV) and pemphigus foliaceus (PF)) and the initiation of a Phase 3 trial of PRN1008 in pemphigus.

As quoted in the press release:

The primary efficacy endpoint of the Phase 2 trial – Control of Disease Activity (CDA) within four weeks – was achieved by more than 50% of patients and PRN1008 was generally well tolerated. Based on the results of the Phase 2 trial, Principia has initiated the PEGASUS study, a global, randomized, double-blind, placebo-controlled, pivotal, Phase 3 clinical trial of PRN1008 in patients with moderate to severe pemphigus.

“Pemphigus is a debilitating disease with high unmet need. We are encouraged by the efficacy and safety results from the Phase 2 trial and are initiating the Phase 3 trial based on these results. This is a key milestone for Principia, and the next step toward bringing this novel oral therapy to patients in need,” said Martin Babler, Chief Executive Officer of Principia.
