MENLO PARK, Calif., May 3, 2017 /PRNewswire/ -- BioPharmX Corporation (NYSE MKT: BPMX), a specialty pharmaceutical company developing products for the dermatology market, today announced that it achieved the primary endpoint in its phase 2b clinical trial evaluating BPX-011, the first completely solubilized topical minocycline gel product candidate for the treatment of moderate-to-severe acne.

From the topline results for the study's primary endpoint, BioPharmX observed in both the 1 percent and 2 percent doses of BPX-01 statistically significant reductions in non-nodular inflammatory acne lesions when compared to vehicle. The absolute mean change in the number of acne lesions from baseline to week 12 for each arm was:
BPX-01 2% (n=72), a reduction of 15.4 compared to baseline (p=0.022 compared to vehicle)
BPX-01 1% (n=73), a reduction of 15.5 compared to baseline (p=0.037 compared to vehicle)
Vehicle (n=74), a reduction of 11.3 compared to baseline
The phase 2b study was a randomized, double-blind, three-arm, vehicle-controlled dose-finding study to assess the efficacy and safety of BPX-01 for the treatment of acne vulgaris. The multi-center study evaluated two concentrations of BPX-01 (1% and 2% minocycline) and vehicle in 226 subjects, aged 9 to 40, with moderate-to-severe inflammatory, non-nodular acne vulgaris.
The phase 2b study also measured reduction in Investigator's Global Assessment (IGA) as a secondary endpoint. This secondary endpoint was defined as the proportion of subjects with at least a two-grade reduction in IGA to clear "0" or almost clear "1." The proportion that achieved this endpoint was 22.7 percent for BPX-01 2%, 16.0 percent for BPX-01 1%, and 17.1 percent for vehicle. Although these secondary endpoint results were not statistically significant, BioPharmX observed in the BPX-01 2% arm a clear numerical trend compared to vehicle. While this trial was not powered for statistical significance for IGA, this endpoint was included to inform the design of the pivotal phase 3 program.
The company has not yet analyzed the safety data from the phase 2b study. There were no serious adverse events related to study treatment reported to the company by the investigators during the trial.
Based on these phase 2b results, BioPharmX continues to progress BPX-01 towards a phase 3 program.
"These results represent a major milestone for the company and offer the potential of BPX-01 as the first topical gel minocycline for moderate-to-severe acne, optimizing safety and efficacy of a proven antibiotic for this condition to millions of patients," said Anja Krammer, co-founder and president of BioPharmX. "We look forward to sharing detailed phase 2b data with the investor and medical communities over the coming months."
BioPharmX will present comprehensive results from the phase 2b study at an event for the investment community in New York next month. The company also plans to submit the data for presentation at an upcoming medical conference and for publication in a peer-reviewed medical journal.
"These positive results are very encouraging and bring hope to the dermatologic community, but most importantly to the patients who suffer physically, emotionally and psychologically from moderate-to-severe acne -- that a new minocycline targeted topical gel will offer treatment for this condition," said Zoe Diana Draelos, board-certified dermatologist at Dermatologist Consulting Services in High Point, North Carolina and a principal investigator in the phase 2b trial.
