-- Company Completed Positive End-of-Phase 2 Meeting with FDA for SNA-120 in Psoriasis

WESTLAKE VILLAGE, Calif., May 08, 2019 (GLOBE NEWSWIRE) --  Sienna Biopharmaceuticals, Inc. (Nasdaq:SNNA) today reported the Company’s financial results for the first quarter of 2019.

“We are pleased to report the results of our first quarter,” said Frederick C. Beddingfield III, M.D., Ph.D., President and Chief Executive Officer of Sienna. “We completed a positive End-of-Phase 2 meeting with the U.S. Food and Drug Administration (FDA) for SNA-120 (pegcantratinib) in psoriasis, and the FDA has agreed with us regarding the general Phase 3 study design, including the primary endpoint, the Investigator Global Assessment (IGA) 2-grade composite, which has been the Phase 3 primary endpoint for recent topical psoriasis drugs approved by the FDA and on which we demonstrated clinically meaningful and statistically significant improvement in our recent Phase 2b clinical trial. We continue to work enthusiastically toward enrolling the first patient in our SNA-120 Phase 3 program later this year.”

Selected Financial Results

Total operating expenses for the three months ended Mar. 31, 2019 were approximately $15.8 million, which includes research and development (R&D) expenses totaling approximately $7.1 million and general and administrative (G&A) expenses totaling approximately $8.7 million. Total operating expenses for the three months ended Mar. 31, 2018 were approximately $18.5 million, which included R&D expenses totaling approximately $13.0 million and G&A expenses totaling approximately $5.5 million. The year-over-year decrease in R&D expenses was due primarily to decreased development costs related to clinical trials for SNA-120 and SNA-001 and decreased manufacturing costs. The year-over-year increase in G&A expenses was due primarily to a $3.1 million increase in the non-cash expense related to the fair value of the contingent consideration liability associated with the Company’s acquisition of Creabilis plc in December 2016. Operating expenses for the three months ended Mar. 31, 2019 also included a one-time expense of $0.8 million related to cash severance payments associated with the January 2019 restructuring.

Cash burn during the three months ended Mar. 31, 2019 was approximately $12.8 million. Sienna’s cash and cash equivalents as of Mar. 31, 2019 totaled approximately $57.2 million, which includes the $21.4 million in net proceeds from the Company’s February 2019 follow-on public offering.
