Results from Serlopitant Phase 2 Clinical Trial for the Treatment of Chronic Pruritus of Unknown Origin Anticipated in Q1 2020
Results from Serlopitant Phase 3 Clinical Trials for the Treatment of Pruritus with Prurigo Nodularis Anticipated in H1 2020
REDWOOD CITY, Calif., Aug. 01, 2019 (GLOBE NEWSWIRE) — Menlo Therapeutics Inc.(Nasdaq: MNLO), a late-stage biopharmaceutical company focused on the development of serlopitant for the treatment of pruritus (itch), today announced financial results for the second quarter ended June 30, 2019 and provided an update on its clinical development programs.
“We are pleased with the progress in our prurigo nodularis (PN) Phase 3 clinical trials and the rapid enrollment in our chronic pruritus of unknown origin (CPUO) Phase 2 clinical trial,” said Steve Basta, Menlo’s Chief Executive Officer. “We believe the rapid enrollment of the CPUO trial reflects the large patient population and significant unmet need to manage pruritus in CPUO patients, for which there is currently no approved treatment.”
Clinical Program Updates
- Menlo is currently conducting two Phase 3 clinical trials (one in the U.S. and one in Europe) to evaluate serlopitant as a treatment for pruritus associated with PN. Each trial is targeted to enroll approximately 280 patients. There are currently 213 patients enrolled in the U.S. trial and 241 patients enrolled in the European trial. Menlo is on track as previously indicated to report top-line data from these PN Phase 3 trials in the first half of 2020.
- Menlo is also currently enrolling patients in a 52-week, multicenter, open-label safety study of serlopitant for the treatment of pruritus. The objective of this study is to provide long-term safety data for serlopitant in adults with pruritus, consistent with ICH and FDA guidelines, which recommend that drugs being developed for long-term treatment be evaluated for safety in at least 100 patients treated for 12 months and 300 patients treated for 6 months. Over 350 patients have been enrolled in this open-label study to date.
Chronic Pruritus of Unknown Origin
- Menlo is conducting a Phase 2 clinical trial in patients with chronic pruritus of unknown origin and expects to enroll approximately 200 patients in this trial. Menlo has enrolled 143 patients in this trial to date. Due to success accelerating enrollment in the CPUO trial, Menlo expects to report top-line data from this trial in the first quarter of 2020, earlier than previously indicated.
- In December 2018, Menlo successfully completed a Phase 2 clinical trial in patients with pruritus associated with psoriasis which met the primary endpoint demonstrating a statistically significant improvement in pruritus in serlopitant-treated patients versus placebo. Menlo has chosen to defer the decision to start a Phase 3 clinical program in pruritus associated with psoriasis until 2020 in consideration of prudent resource prioritization and allocation management. Menlo plans to further clarify with the FDAthe target population of patients for the proposed program, consider any learnings from its ongoing PN and CPUO trials once complete, and evaluate the opportunity in psoriasis compared to potential alternative investments, such as accelerating the CPUO development program.
Second Quarter 2019 Financial Results
Menlo reported a net loss attributable to common stockholders of $16.5 million for the second quarter of 2019, compared to a net loss of $8.3 million for the same period in 2018.
Collaboration and license revenue was zero in the second quarter of 2019 compared to $10.1 million for the same period in 2018. The decrease in collaboration and license revenue was due to the termination of Menlo’s collaboration agreement with JT Torii in June 2018.
Research and development expenses were $13.5 million in the second quarter of 2019, compared to $16.2 million for the same period in 2018. The decrease was primarily due to a May 2018$3.0 million milestone payment to Merck resulting from the initiation of Menlo’s Phase 3 clinical trials for pruritus associated with prurigo nodularis.
General and administrative expenses were $3.8 million in the second quarter of 2019, compared to $3.1 million for the same period in 2018. The increase was primarily due to an increase in personnel expenses as a result of an increase in Menlo’s employee headcount and stock-based compensation expense and an increase in professional and insurance fees.
As of June 30, 2019, Menlo had $109.4 million in cash, cash equivalents and investments, compared to $136.3 million as of December 31, 2018. In the second quarter of 2019, Menlo issued 246,416 shares of its common stock pursuant to its at-the-market program at an average price of $7.84 per share and received aggregate net proceeds of $1.9 million after deducting sales agent fees.
Updated Operating Expense and Cash Runway Guidance
Menlo is lowering its operating expense guidance for the full year 2019 to a range of approximately $74.0 to $80.0 million, including stock-based compensation of approximately $5.0 to $6.0 million, from a range of $78.0 to $88.0 million. The decrease is primarily due to Menlo deferring the decision to start a Phase 3 clinical program in pruritus associated with psoriasis until 2020. Menlo expects that its current cash, cash equivalents and investments will enable the company to fund its anticipated operating expenses and capital expenditure requirements into the first quarter of 2021.
