BioPharmX Announces Last Patient Visit in Phase 2b Trial of BPX-04 for Papulopustular Rosacea

SAN JOSE, Calif., May 22, 2019 /PRNewswire/ -- BioPharmX Corporation (NYSE American: BPMX), a specialty pharmaceutical company focused on developing innovative medical dermatology products, announced today that the last patient in the Company's Phase 2b clinical trial of BPX-04¹, a novel topical gel formulation of fully solubilized minocycline for the treatment of papulopustular rosacea, has completed their last clinical visit.

"We are pleased to announce this important milestone and look forward to reporting topline results from the study in early July 2019, subject to successful database lock and results validation," said Dr. David S. Tierney, BioPharmX Chief Executive Officer.

The randomized, double-blind, vehicle-controlled study enrolled 206 subjects with moderate-to-severe papulopustular rosacea. The multicenter study is evaluating the safety and efficacy of once daily application of BPX-04, a 1% minocycline gel, versus a vehicle control over a 12-week treatment period. The study's primary endpoint is the mean change in the number of facial inflammatory lesions of rosacea from baseline to week 12.

About BPX-04
BPX-04 is a novel topical gel formulation of fully solubilized minocycline for the treatment of papulopustular rosacea. The product candidate leverages the HyantX™ topical delivery system, an anhydrous hydrophilic gel formulation, designed for rapid absorption of active pharmaceutical ingredients into the skin rather than remaining on the surface, a common problem with oil‑based ointments and suspensions.

About Rosacea
Rosacea is a chronic dermatologic condition characterized by redness, stinging and inflammatory lesions primarily on the face. The biology of rosacea remains unclear, however it is thought to be an inflammatory disorder that involves immune responses and microorganisms. Rosacea is estimated to affect more than 16 million people in the United States alone, according to the National Rosacea Society. Current treatment options, while limited, include oral antibiotics, anti-parasitics, azelaic acids and alpha-A agonists.
