¾ 356 subjects were randomized to DFD-01, 90 subjects to AugBD, and 182 subjects to Vehicle. ¾ Individual sign scores all showed improvement with treatment, and DFD-01 showed significantly greater effect than AugBD at day 4 for erythema (23.6% vs 12.2%, P=.021) and scaling (39.6% vs 25.6%, P=.014) (Figure 1). ¾ Reduction in TSS was greater with DFD-01 than with AugBD at day 4 (-17.3% vs -10.6%, P=.009) (Figure 2). ¾ At day 4 DFD-01 was also significantly different from AugBD for both TSS50 (13.2% vs 5.6%, P=.044) and TSS≤1 for any sign (13.8% vs 5.6%, P=.031). DFD-01, a VCA midpotent betamethasone dipropionate 0.05% emollient-like spray formulation, demonstrates earlier onset of action compared with a super potent topical steroid for the treatment of moderate psoriasis Leon Kircik, MD1; Jonathan S.

Methods Figure 1. Pooled Analysis of Early Onset of Relief of Erythema and Scaling ¾ Data from two phase 3, randomized, clinical trials enrolling adults with moderate plaque psoriasis (IGA=3; 10% to 20% BSA) were pooled. ¾ Subjects were randomized to receive DFD-01, AugBD, or Vehicle Spray (Vehicle) and products were applied to all affected areas on the body excluding face, scalp, and intertriginous areas twice daily for 14 or 29 days. DFD-01 was applied for 29 days and AugBD was applied for 14 days per their respective labels. ¾ Treatment success at days 4 and 8 was defined as IGA=0 or 1 and ≥2 grade improvement from baseline. ¾ Reduction in total sign score (TSS) for a target lesion (the sum of erythema, plaque and elevation scores), individual sign scores, TSS50 and TSS≤1 for any sign, were also assessed. Analysis was by Fisher’s exact test. Financial Support: This study was funded by the Dr. Reddy’s Laboratories group of companies. DRL Publication # 794 Results Figure 2.
