Sienna Biopharmaceuticals Reports Fourth Quarter and Full Year 2018 Financial Results
WESTLAKE VILLAGE, Calif., Mar. 14, 2019 Sienna Biopharmaceuticals, Inc. (Nasdaq:SNNA), a clinical-stage biopharmaceutical company, today reported the Companys financial results for the fourth quarter and full year of 2018.
We are pleased to report the results of our 2018 fourth quarter and full year and contemplate the possibilities in 2019, particularly in light of our streamlined focus on strategic priorities and successful equity raise, said Frederick C. Beddingfield III, M.D., Ph.D., President and Chief Executive Officer of Sienna. Our drive to bring unconventional scientific innovations to patients whose lives remain burdened by their disease without compromising safety has unlocked a pipeline of selective kinase inhibitors that target select pathways in specific tissues to treat a variety of chronic inflammatory and immunologic conditions with minimal to no systemic exposure. We are poised to begin Phase 3 enrollment for SNA-120 (pegcantratinib) later this year as a potential first-in-class, non-steroidal treatment for psoriasis and the associated pruritus. Additionally, we continue to see potential in SNA-125, our tissue-targeted JAK3/TrkA dual kinase inhibitor, for other inflammatory disorders of the skin, as well the gastrointestinal tract, the eye and the lung. Indeed, with additional funding through a business-development transaction or other means, we would plan to move SNA-125 forward with a Phase 2 trial in atopic dermatitis, as well as with a proof-of-concept study in ulcerative colitis, where the need for gut-restricted drugs with low systemic exposure is high. We are actively seeking a strategic partner for SNA-001, with positive results now in hand that provide a potential path to regulatory clearance. Our future is bright, and we look forward to translating our scientific aptitude and curiosity into new possibilities and positivity for patients who continue to suffer from autoimmune and inflammatory disorders across multiple therapeutic areas.
In February 2019, Sienna closed a follow-on public offering of 9,200,000 shares of common stock at a public offering price of $2.50 per share, which included the exercise in full by the underwriters of their option to purchase up to an additional 1,200,000 shares of common stock. Net proceeds to the Company were approximately $21.3 million, after underwriting discounts, commissions and estimated offering expenses.
Sienna announced on Feb. 8, 2019, top-line results from three pivotal clinical trials for the reduction of light-pigmented hair and from the third and final pivotal clinical trial in acne with SNA-001, a topical, ready-to-use suspension of silver particles to be used as a pre-treatment in conjunction with the most common commercial lasers already utilized in aesthetic clinics and laser centers today. The data showed SNA-001 successfully removed light hair when used with an 810 nm Diode laser and met the primary endpoint of non-inferiority in hair reduction (-17.5% with SNA-001+Laser compared to -1.1% with vehicle+Laser following six treatment sessions). In additional analyses, SNA-001 was statistically superior compared to vehicle+Laser, demonstrating up to a 32% reduction of light hair from baseline. SNA-001 was also evaluated in conjunction with a 1064 Nd:YAG and 755 nm Alexandrite laser for the reduction of light hair, showing a significant reduction from baseline and providing a potential path to regulatory clearance. These results, however, were less differentiated from the vehicle+Laser group compared to the 810 nm Diode laser study results. The third and final pivotal trial of SNA-001 in acne demonstrated SNA-001 was non-inferior to laser therapy. In all of these trials, SNA-001 was well tolerated, with no unexpected, treatment-related adverse events observed. These results provide a potential path to regulatory clearance in light-pigmented hair removal and acne, and the Company is seeking a strategic partner to maximize the value of SNA-001.
Sienna announced on Dec. 3, 2018, that the Companys tissue-targeted Tropomyosin receptor kinase A (TrkA) inhibitor, SNA-120 (0.05%), demonstrated in a Phase 2b clinical trial statistically significant improvement compared to vehicle on important pre-specified endpoints of psoriasis disease severity, including the Investigators Global Assessment (IGA) 2-grade composite, comprising a 2-grade improvement from baseline and clear (0) or almost clear (1) skin, which has been the Phase 3 primary endpoint for recent topical psoriasis drugs approved by the U.S. Food and Drug Administration (FDA). Specifically, 29% of patients achieved success on the IGA 2-grade composite, compared to 13% of subjects treated with vehicle. Additionally, 27% of subjects experienced a 75% reduction from baseline in their Psoriasis Area and Severity Index score (PASI 75), compared to 13% of subjects treated with vehicle. Subjects also experienced an approximately 60% reduction from baseline in the associated pruritus (itch), although the pruritus result did not reach statistical significance compared to vehicle. SNA-120 has been administered to more than 500 subjects for up to 12 weeks and has been well tolerated across all trials, with minimal to no demonstrated systemic bioavailability. Following an End-of-Phase 2 (EOP2) meeting with the FDA scheduled for April 2019, Sienna intends to initiate two Phase 3 pivotal clinical trials for a psoriasis indication, subject to securing sufficient capital to complete both trials, in the second half of 2019.
Sienna announced on Dec. 3 and Aug. 27, 2018, results from exploratory Phase 1/2 studies in atopic dermatitis and psoriasis, respectively, with SNA-125, the Companys dual Janus kinase 3 (JAK3)/TrkA inhibitor. In these studies, SNA-125 was well tolerated and showed no safety signals. Additionally, histological and biomarker analyses showed a modest drug effect in both atopic dermatitis and psoriasis, despite using a prototype gel formulation and treating a limited area for a short duration. Sienna intends to initiate a Phase 2 study with a more optimal cream formulation of SNA-125 first in atopic dermatitis, subject to securing sufficient capital to complete the trial.
Selected Financial Results
Total operating expenses for the three months ended Dec. 31, 2018, were approximately $19.8 million, which includes research and development (R&D) expenses totaling approximately $10.8 million and general and administrative (G&A) expenses totaling approximately $9.0 million. Total operating expenses for the three months ended Dec. 31, 2017, were approximately $14.0 million, which included R&D expenses totaling approximately $9.5 million and G&A expenses totaling approximately $4.5 million. The year-over-year increase in R&D expenses was due primarily to increased development costs related to SNA-120 and SNA-125, partially offset by a reduction in costs related to the pivotal trials for SNA-001. The year-over-year increase in G&A expenses was due primarily to a $4.9 million non-cash increase in expense related to the fair value of the contingent consideration liability associated with the Companys acquisition of Creabilis plc in December 2016, partially offset by a reduction in legal fees.
Total operating expenses for the twelve months ended Dec. 31, 2018, were approximately $76.5 million, which includes R&D expenses totaling approximately $51.6 million and G&A expenses totaling approximately $24.9 million. Total operating expenses for the twelve months ended Dec. 31, 2017, were approximately $48.6 million, which included R&D expenses totaling approximately $30.5 million and G&A expenses totaling approximately $18.1 million. The year-over-year increase in R&D expenses was due primarily to increased development costs related to the clinical trials for SNA-120 and for SNA-125, increased manufacturing costs to support the clinical trials for SNA-120 and SNA-125 and increased costs related to early stage research activities, offset by a reduction in costs related to the 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 a $3.3 million non-cash increase in expense related to the fair value of the contingent consideration liability associated with the Companys acquisition of Creabilis plc in December 2016.
Cash burn during the three months ended Dec. 31, 2018, was approximately $15.6 million. Cash burn during the twelve months ended Dec. 31, 2018, was approximately $61.7 million. Siennas cash and cash equivalents as of Dec. 31, 2018, totaled approximately $48.5 million, which does not include the $21.3 million in net proceeds from the Companys February 2019 follow-on public offering.
