Skye Bioscience Reports First Quarter 2025 Results and Highlights Nimacimab Differentiation in Obesity

• Nimacimab in combination with tirzepatide improves weight loss effect over tirzepatide alone, and shows comparable weight loss to monlunabant and tirzepatide alone in preclinical diet-induced obesity model
• In vitro data reported from new preclinical study highlights superior potency of peripherally restricted CB1 inhibitor, nimacimab, versus monlunabant when tested under pathological levels of CB1 agonists
• Expanded preclinical study data to be presented at ADA in June 2025
• Top-line data readout from CBeyond™ Phase 2a study of nimacimab expected late Q3/early Q4 2025

SAN DIEGO, May 08, 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 first quarter ended March 31, 2025, along with key accomplishments and upcoming milestones.

“In Q1, we made decisive progress across clinical operations and R&D,” said Punit Dhillon, President & CEO of Skye. “Nimacimab continues to demonstrate a differentiated profile as a potential weight loss therapy, with a peripherally restricted mechanism that may set it apart from both GLP-1s and small-molecule CB1 inhibitors. We’re advancing a body of preclinical and clinical evidence that supports its potential in reshaping the treatment landscape in obesity.”

Clinical Highlights: CBeyond™ Phase 2 Obesity Trial

• Clinical engagement remains strong: Patients continue to receive active treatment and are progressing through scheduled follow-ups, supported by ongoing collaboration between the clinical team and study sites.
• Safety reviews: Data Safety Monitoring Committee has completed three reviews with no concerns raised. The study continues per protocol.
• Institutional Review Board (“IRB”) approval: The IRB has approved the open-label study extension to 52 weeks. We are finalizing the study protocol with the FDA in preparation for enrollment.
  

Research & Development Highlights

• Preclinical data: Preclinical data further demonstrated the potential efficacy and potency of nimacimab.
• Enhanced safety: Diet-induced obesity (“DIO”) mouse model data highlighted the sufficiency of the highly-peripherally restricted CB1 inhibitor nimacimab--without central (brain) exposure--to drive weight loss, with similar efficacy compared to the less-peripherally restricted CB1 inhibitor monlunabant, which may be challenged by brain exposure and the risk of neuropsychiatric side effects.
  • Nimacimab combined with the dual GLP-1/GIP agonist tirzepatide achieved over 30% weight loss
  • Nimacimab alone produced 23.5% weight loss, comparable to monlunabant and tirzepatide alone in this study.
• Superior potency: In vitro, nimacimab’s differentiated and favorable mechanism of CB1 inhibition showed superior potency versus the small molecule CB1 inhibitor monlunabant under the elevated concentrations of CB1 agonist associated with obesity.
  

First Quarter 2025 Financial Results:

Balance Sheet Highlights:

• Cash and cash equivalents and short-term investments totaled $59.2 million as of March 31, 2025. The Company expects its current capital to fund projected operations and key clinical milestones through at least Q1 2027, which includes the completion of its extended Phase 2a study for nimacimab and Phase 2b manufacturing but excluding the Phase 2b clinical study and manufacturing activities necessary to supply later stage studies.
  

Operating Results:

• R&D Expenses:
  
  Research and development (R&D) expenses for the three months ended March 31, 2025, were $7.2 million, as compared to $1.9 million for the same period in 2024. The increase was primarily due to contract manufacturing and clinical trial costs associated with our Phase 2a clinical study for nimacimab, salaries and stock based compensation, consulting and depreciation expense.

• G&A Expenses:
  
  General and administrative (G&A) expenses for the three months ended March 31, 2025, were $4.6 million, as compared to $4.2 million for the same period in 2024. The increase was primarily related to investor relations, marketing and communication costs and consulting and advisory fees.

• Net Loss:
  
  Net loss for the three months ended March 31, 2025, totaled $11.1 million, with non-cash share-based compensation expense of $2.2 million, compared to $5.0 million for the same period in 2024, with non-cash share-based compensation expense of $2.5 million.

ABOUT SKYE BIOSCIENCE

Skye is focused on unlocking new therapeutic pathways for metabolic health through the development of next-generation molecules that modulate G-protein coupled receptors. Skye's strategy leverages biologic targets with substantial human proof of mechanism for the development of first-in-class therapeutics with clinical and commercial differentiation. Skye is conducting a Phase 2a clinical trial (ClinicalTrials.gov: NCT06577090) in obesity for nimacimab, a negative allosteric modulating antibody that peripherally inhibits CB1. This study is also assessing the combination of nimacimab and a GLP-1R agonist (Wegovy®). For more information, please visit: www.skyebioscience.com. Connect with us on X and LinkedIn.
