• Topline nimacimab Phase 2a study data showed clinically meaningful weight loss in nimacimab/semaglutide combination cohort versus semaglutide alone after 26 weeks of treatment; the data demonstrated a clean neuropsychiatric safety profile and no increase in gastrointestinal adverse events.
• Nimacimab plus semaglutide showed additional reduction in waist circumference of -3.2 cm vs. semaglutide alone.
• Rebound weight gain was lower in the 12-week post-treatment follow-up period in patients treated with nimacimab plus semaglutide vs. semaglutide alone.
  

SAN DIEGO, Nov. 10, 2025 (GLOBE NEWSWIRE) -- Skye Bioscience, Inc. (Nasdaq: SKYE) (“Skye” or the“Company”), a clinical stage biotechnology company developing next-generation molecules that modulate G-protein-coupled receptors to treat obesity, overweight, and related conditions, today reported financial results for the third quarter ended September 30, 2025, along with key accomplishments and upcoming milestones.

“As we obtain additional data from our CBeyond Phase 2a study, a holistic review provides us with additional confidence that nimacimab's biology is active and has the potential to fill notable gaps in the obesity and overweight landscape in order to support a healthier weight loss journey for patients,” said Punit Dhillon, President & CEO of Skye.“With the positive combination data, we are shifting our focus to a combination development pathway while simultaneously planning to further understand nimacimab's potential benefit in a monotherapy setting. We anticipate that forthcoming biomarker data and the readout from the 26-week extension will continue to build upon this story and provide further insights into nimacimab's full potential as a metabolic therapy.”

Clinical Highlights: CBeyond ^TM Phase 2a Obesity Trial

• Phase 2a Data Highlights:
  • In October 2025, Skye reported 26-week topline data from its ongoing CBeyond Phase 2a study demonstrating a 29% relative increase in weight loss when nimacimab was dosed in combination with semaglutide compared to semaglutide alone.
  • At ObesityWeek 2025, Skye shared new weight rebound data highlighting that after treatment discontinuation nimacimab plus semaglutide blunted rebound weight gain compared to semaglutide alone (18.1% versus 49.8% weight regained over 12 weeks). Moreover, at 12 weeks post-treatment, the nimacimab plus semaglutide group maintained significant weight loss compared to the placebo group.
  • The nimacimab plus semaglutide combination also achieved an additional decrease in waist circumference of 3.2 cm (1.25 inches) compared to patients treated with semaglutide alone.
  • In the context of the obesity treatment landscape, we believe that this data highlights nimacimab's potential as a combination or maintenance therapy by supplementing GLP-1 therapeutics to enhance weight loss and improve body composition by targeting fat loss, without adding gastrointestinal side effects.
• Extension Study Fully Enrolled:
  • In September, Skye completed the enrollment of its 26-week extension study. A total of 43 patients were enrolled, with 19 and 24 patients in the combination and monotherapy cohorts, respectively.
  • Data from the 26-week extension is expected in Q1 2026 and will provide information on the potential full treatment duration of 52 weeks followed by a 12-week follow-up period.
  • In the combination arms, patients will continue with blinded treatment with nimacimab or placebo and will continue receiving semaglutide (Wegovy®). Patients in the monotherapy arm will receive a higher dose of nimacimab (300 mg), which we expect will assist in refining our PK model.
    

Third Quarter 2025 Financial Results:

Balance Sheet and Cash Flow Highlights:

• Cash, cash equivalents and short-term investments totaled $35.3 million as of September 30, 2025. The Company expects its current capital to fund projected operations and key clinical milestones into 2027, including completion of its Phase 2a extension study of nimacimab and certain manufacturing and clinical activities, initial manufacturing runs needed to start a subsequent trial, and planning activities. In addition, our runway supports our discovery, research and development efforts along with formulation and development work in preparation for nimacimab's later stage studies.
  

Operatin g Results:

• R&D Expenses:
  Research and development (R&D) expenses for the three months ended September 30, 2025, were $9.4 million, as compared to $4.9 million for the same period in 2024. The increase was primarily due to contract manufacturing, clinical trial costs associated with our clinical study for nimacimab, discovery research and development expenses, salaries and stock based compensation expense, and consulting advisory and professional fees.

• G&A Expenses:
  General and administrative (G&A) expenses for the three months ended September 30, 2025, were $3.9 million, as compared to $4.6 million for the same period in 2024. The decrease was primarily related to decreases in consulting, advisory and professional fees, recruitment fees, salaries, and stock based compensation expense.

• Net Loss:
  Net loss for the three months ended September 30, 2025, totaled $12.8 million, with non-cash stock-based compensation expense of $1.9 million, compared to $3.9 million for the same period in 2024, with non-cash stock-based compensation expense of $1.9 million.
