In Development For The Treatment Of Acne Vulgaris
SB204 is a topical monotherapy in development for the treatment of acne vulgaris, a multi-factorial disease  involving 4 key pathophysiological factors including inflammation and bacterial colonization.1 SB204 utilizes the same active pharmaceutical ingredient used in berdazimer gel 10.3% (SB206), and is formulated specifically to address acne via an anti-inflammatory and anti-bacterial activity.2

In two previous Phase 3 studies, AC301 and AC302, SB204 demonstrated consistent and promising results across two of three co-primary endpoints. In addition, AC302 was a successful pivotal trial with respect to all three co-primary endpoints, including non-inflammatory lesions, inflammatory lesions, and Investigator’s Global Assessment (IGA). Based on the recent positive pivotal Phase 3 results in the berdazimer gel 10.3% (SB206) molluscum development program, Pelthos believes it can optimize the trial design of a pivotal Phase 3 study for SB204 which has the potential to serve as a second pivotal trial to support an NDA submission.

Program Highlights:

  • AC302 was a successful pivotal Phase 3 trial across all three co-primary endpoints

  • Consistent results across AC301 and AC302 for two of three co-primary endpoints

  • Positive B-SIMPLE4 results validated our technology and our effective trial execution
