BRIDGEWATER, N.J., Aug. 14, 2024 (GLOBE NEWSWIRE) — VYNE Therapeutics Inc. (Nasdaq: VYNE) (“VYNE” or the “Company”), a clinical-stage biopharmaceutical company focused on developing differentiated therapies to treat chronic inflammatory and immune-mediated conditions with high unmet need, today announced financial results as of and for the three and six months ended June 30, 2024 and provided a business update.

“We advanced our clinical programs in the second quarter of 2024, highlighted by the initiation of our Phase 2b trial of VYN201 and the Phase 1a trial of VYN202,” said David Domzalski, President and Chief Executive Officer of VYNE. “We are pleased with the progress we are making with both clinical programs. We remain on track to report top-line data from our Phase 2b clinical trial for VYN201 in subjects with nonsegmental vitiligo in the middle of next year. We also expect to report top-line data from the single ascending dose portion of the Phase 1a trial of VYN202 this quarter, followed by results from the multiple ascending dose portion in the fourth quarter. Upon the successful completion of this Phase 1a trial, we plan to advance VYN202 into two Phase 1b proof-of-concept trials with top-line readouts in the second half of next year.”

Recent Pipeline Updates

VYN201

• VYN201 is a locally administered pan-bromodomain (“BD”) BET inhibitor designed as a “soft” drug to address diseases involving multiple, diverse inflammatory cell signaling pathways while providing low systemic exposure. VYNE initiated a Phase 2b trial of VYN201 in nonsegmental vitiligo in June 2024. The Phase 2b trial is a randomized, double-blind, vehicle-controlled trial evaluating the efficacy, safety and pharmacokinetics of once-daily VYN201 gel in three dose cohorts (1%, 2% and 3% concentrations) compared to vehicle for 24 weeks. Subjects are being randomized at 1:1:1:1 ratio. Following the 24-week treatment period, subjects in the 1%, 2%, and 3% cohorts will continue treatment with their respective dose concentrations for an additional 28-week open label extension. Subjects in the vehicle group during the initial 24-week treatment period will be equally re-randomized to receive VYN201 1%, 2% or 3% gel for an additional 28 weeks. VYNE expects to enroll approximately 40 subjects in each arm and to report top-line results from the 24-week double-blind portion of the trial in mid-2025.

VYN202

• VYN202 is an oral small molecule BD2-selective BET inhibitor designed to achieve potential class-leading selectivity and potency (BD2 vs. BD1). A first-in-human Phase 1a single ascending dose/multiple ascending dose (“SAD/MAD”) trial was initiated in June 2024. VYNE expects to report top-line results from the SAD and MAD portions of the trial in the third and fourth quarters of 2024, respectively. If the Phase 1a trial is successfully completed, VYNE plans to initiate Phase 1b trials in adult subjects with moderate-to-severe plaque psoriasis and moderate-to-severe rheumatoid arthritis, with top-line results anticipated in the second half of 2025.

Recent Corporate Update

• In July, VYNE appointed Subhashis Banerjee, M.D., as Senior Vice President of Clinical Development. Dr. Banerjee is a trained immunologist and rheumatologist with over 25 years of drug development experience at large pharmaceutical companies, including the development of therapies for psoriasis and arthritic conditions. He most recently served as Vice President & Disease Area Head, Rheumatology and Dermatology at Bristol Myers Squibb. Dr. Banerjee played a key role in the development strategy of immunology assets across multiple platforms for several immune-mediated diseases, including SOTYKTU® (deucravacitinib), ORENCIA® (abatacept), clazakizumab (anti-IL-6 antibody), TALTZ® (ixekizumab, anti-IL-17 antibody) and XELJANZ® (tofacitinib).

Financial Results as of and for the Second Quarter Ended June 30, 2024

Cash position. As of June 30, 2024, VYNE had cash, cash equivalents, restricted cash and marketable securities of $78.1 million. VYNE believes its cash, cash equivalents, restricted cash and marketable securities as of June 30, 2024 will be sufficient to fund its operations through the end of 2025.

Revenues. Revenues totaled $0.2 million and $0.1 million for each of the quarters ended June 30, 2024 and 2023, respectively, consisting of royalty revenue from the Company’s royalty agreement with LEO Pharma, to whom VYNE previously licensed the rights to Finacea® foam.

Research and development expenses. VYNE’s research and development expenses for the quarter ended June 30, 2024 were $7.3 million, representing an increase of $0.1 million, or 1.0%, compared to $7.2 million for the quarter ended June 30, 2023. The increase was primarily driven by expenses related to preparatory and clinical trial activities for a Phase 2b trial of VYN201 in subjects with nonsegmental vitiligo, which was initiated in June 2024, of $3.2 million, including a $1.0 million development milestone payment due to Tay Therapeutics Ltd. (“Tay”) upon the initiation of the Phase 2b trial. In addition, employee-related expenses increased by $0.3 million following the hiring of additional research and development personnel. These increases were partially offset by a decrease in expenses associated with VYN202 of $3.5 million, primarily driven by lower amounts owed to Tay under the license agreement with respect to VYN202 (the “VYN202 License Agreement”). In April 2023, VYNE made a one-time cash payment of $3.75 million to Tay in connection with entering into the VYN202 License Agreement. In the second quarter of 2024, the Company incurred a $1.0 million development milestone payment due to Tay following the initiation of a Phase 1a SAD/MAD trial of VYN202.

General and administrative expenses. VYNE’s general and administrative expenses for the quarter ended June 30, 2024 were $3.3 million, representing an increase of $0.1 million, or 2.1%, compared to $3.2 million for the quarter ended June 30, 2023. The increase was primarily driven by consulting and professional fees.

Net loss. Net loss and net loss per share for the quarter ended June 30, 2024 were $9.4 million and $0.22, respectively, compared to a net loss and net loss per share of $10.1 million and $3.09, respectively for the comparable period in 2023.
