Sienna Biopharmaceuticals® Reports Third Quarter 2018 Financial Results

WESTLAKE VILLAGE, Calif., Nov. 8, 2018 – Sienna Biopharmaceuticals, Inc. (NASDAQ:SNNA), a clinical-stage medical dermatology and aesthetics company, today reported the Company’s financial results for the third quarter of 2018.

“We are pleased to report the results of our third quarter,” said Frederick C. Beddingfield III, MD, PhD, President and Chief Executive Officer of Sienna Biopharmaceuticals®. “August 1 marked the completion of Sienna’s first full year as a public company, and we continue to execute on our plans to bring innovative topical therapies to dermatology and aesthetics practitioners and their patients. Our team is excited, optimistic and focused, working toward clinical data this quarter from our Phase 2b trial with SNA-120 (pegcantratinib) in pruritus associated with psoriasis, as well as our Phase 1/2 exploratory trial with SNA-125 in atopic dermatitis and the first of our pivotal trials with SNA-001 for the reduction of unwanted light-pigmented hair.”

Pipeline Overview

Sienna’s pipeline currently includes multiple clinical-stage programs:

(from the Company’s Topical by Design™ platform)

 

   

SNA-120 for the treatment of pruritus associated with psoriasis and the underlying psoriasis; Phase 2b top-line results expected in the fourth quarter of 2018

 

   

SNA-125 for the treatment of atopic dermatitis; Phase 1/2 results expected in the fourth quarter of 2018

(from the Company’s Topical Photoparticle Therapy™ platform)

 

   

SNA-001 for the reduction of light-pigmented hair

 

   

pivotal results with the 1064 nm wavelength laser expected in the fourth quarter of 2018

Selected Financial Results

Total operating expenses for the three months ended Sept. 30, 2018, were approximately $16.6 million, which includes research and development (R&D) expenses totaling approximately $12.1 million and general and administrative (G&A) expenses totaling approximately $4.4 million. Total operating expenses for the three months ended Sept. 30, 2017, were approximately $14.3 million, which included R&D expenses totaling approximately $9.4 million and G&A expenses totaling approximately $4.9 million. The year-over-year increase in R&D expenses was due primarily to increased development costs related to the initiation of clinical trials for SNA-120 and for SNA-125 and increased manufacturing costs related to SNA-125, offset by a reduction in costs related to the ongoing pivotal trials for SNA-001 and a reduction in manufacturing costs related to SNA-120. The year-over-year decrease in G&A expenses was due primarily to a $1.8 million non-cash decrease in the fair value of the contingent consideration liability related to the Company’s acquisition of Creabilis plc in December 2016 and a reduction in legal fees, offset by an increase in personnel costs and an increase in costs related to being a public company.

Total operating expenses for the nine months ended Sept. 30, 2018, were approximately $56.7 million, which includes R&D expenses totaling approximately $40.8 million and G&A expenses totaling approximately $15.9 million. Total operating expenses for the nine months ended Sept. 30, 2017, were approximately $34.6 million, which included R&D expenses totaling approximately $21.0 million and G&A expenses totaling approximately $13.6 million. The year-over-year increase in R&D expenses was due primarily to increased development costs related to the initiation of clinical trials for SNA-120 and for SNA-125, increased manufacturing costs related to SNA-125 and increased costs related to early stage research activities, offset by a reduction in costs related to the ongoing pivotal trials for SNA-001. The year-over-year increase in G&A expenses was due primarily to an increase in personnel costs, an increase in expenses related to marketing research and an increase in costs related to being a public company, offset by a $1.6 million non-cash decrease in the fair value of the contingent consideration liability related to the Company’s acquisition of Creabilis plc in December 2016 and a reduction in consulting and legal fees.

Cash burn during the three months ended Sept. 30, 2018, was approximately $15.9 million. Cash burn during the nine months ended Sept. 30, 2018, was approximately $46.1 million. Sienna’s cash and cash equivalents as of Sept. 30, 2018, totaled approximately $64.0 million.
