EPI Health, a Novan Company, and MC2 Therapeutics Present WYNZORA® (calcipotriene and betamethasone dipropionate) Cream, 0.005%/0.064% Subgroup Data Analysis at Skin of Color Update 2022 Conference

– New data analysis from previously completed successful Phase 3 study¹ demonstrated WYNZORA^® Cream to be effective and convenient for skin of color patients for the treatment of plaque psoriasis

DURHAM, N.C. and COPENHAGEN, Denmark, Sept. 15, 2022 (GLOBE NEWSWIRE) — Novan, Inc. (“the Company” or “Novan”) (Nasdaq: NOVN), today announced that EPI Health, a Novan Company, and MC2 Therapeutics presented data from a previously unpublished subgroup analysis of the U.S. Phase 3 pivotal study of WYNZORA^® Cream at the Skin of Color Update 2022 Conference held September 9-11, 2022, in New York, NY.

Published as a poster, this analysis from a previously completed Phase 3 randomized, multicenter, investigator-blind, parallel-group trial of WYNZORA^® Cream (calcipotriene and betamethasone dipropionate) evaluated efficacy and convenience factors in skin of color patients compared to the total study population. Patients with skin of color (Fitzpatrick IV-VI) made up 36% of subjects in the WYNZORA^® head-to-head study, and 8% were African American. The proportion of patients (37.4%) in the Fitzpatrick type IV-VI group achieving Physician Global Assessment (PGA) success (at least a 2-grade improvement from baseline and clear or almost clear) after 8 weeks of treatment with CAL/BDP (calcipotriene and betamethasone dipropionate) cream was similar to the total population (38.7%) and significantly different from CAL/BDP TS (topical suspension) (p=0.0042) and cream vehicle (p=0.0013). The change from baseline mPASI after 8 weeks of treatment in the skin of color population was 61.8% with CAL/BDP Cream and 47.7% with CAL/BDP TS (p=0.0003), compared to 62.2% CAL/BDP Cream and 52% CAL/BDP TS in the total population (p<0.0001). No cases of hypopigmentation were reported in the Phase 3 trial.

This subgroup analysis shows that skin of color patients treated with CAL/BDP cream have similar efficacy to the total trial population. Patient convenience and satisfaction for CAL/BDP cream were scored similarly or higher in patients with skin of color than in the total trial population and compared to CAL/BDP TS.

“Patients with skin of color are typically not well represented in topical psoriasis studies. This data enables us to understand the efficacy of WYNZORA^® Cream in this population, which comprised more than one third of patients enrolled. The results from this analysis demonstrated similar efficacy and comparable or higher scores for convenience factors (such as how easy the treatment was to apply) in Fitzpatrick skin type IV to VI subjects, giving us further confidence in using WYNZORA^® for these patients,” commented Fran Cook-Bolden M.D., Assistant Clinical Professor, Weill Cornell Medicine New York, NY and an investigator for the WYNZORA Cream US Phase 3 study.
