Core Insights - Ascletis Pharma Inc. announced that denifanstat (ASC40), a first-in-class oral fatty acid synthase (FASN) inhibitor, successfully met all primary and secondary endpoints in a Phase III clinical trial for moderate to severe acne vulgaris [1][6][10] Clinical Trial Overview - The Phase III trial was a randomized, double-blind, placebo-controlled study conducted in China with 480 patients, comparing 50 mg denifanstat to a placebo over 12 weeks [2] - Baseline characteristics were well balanced between the treatment and placebo groups, with total lesion counts of 102.2 for denifanstat and 102.1 for placebo [11] Efficacy Results - Primary endpoints showed a treatment success rate of 33.2% for denifanstat versus 14.6% for placebo (p<0.0001) [3] - Denifanstat achieved a 57.4% reduction in total lesion count compared to 35.4% for placebo (p<0.0001) and a 63.5% reduction in inflammatory lesions compared to 43.2% for placebo (p<0.0001) [3] - Key secondary endpoint results included a 51.9% reduction in non-inflammatory lesions for denifanstat versus 28.9% for placebo (p<0.0001) [3] Safety Profile - Denifanstat demonstrated a favorable safety and tolerability profile, with treatment-emergent adverse events (TEAEs) comparable to placebo [4] - No TEAEs related to denifanstat exceeded 10%, and all reported adverse events were mild or moderate [4] Mechanism of Action - Denifanstat works by directly inhibiting facial sebum production and inflammation, addressing the underlying causes of acne [5] - This mechanism differentiates denifanstat from other acne treatments that do not target the root cause of the condition [5] Comparative Efficacy - In non-head-to-head comparisons, denifanstat was found to be 98% and 178% more effective than sarecycline and doxycycline, respectively, in terms of placebo-adjusted treatment success [7][8] - Denifanstat was also 60% more effective than clascoterone cream regarding treatment success [7][8] Market Potential - Denifanstat is positioned as a first-in-class oral acne therapeutic with exceptional efficacy and a favorable safety profile, potentially improving patient compliance compared to topical treatments [9] - The company plans to submit denifanstat for approval to the China National Medical Products Administration (NMPA) [6]
