• Enrollment completed in Phase 2a CBeyond™ trial of CB1 inhibitor, nimacimab, in obesity and overweight
• Faster-than-expected enrollment enables full top-line Phase 2a data in late Q3/early Q4 2025, ahead of schedule; interim analysis removed
• Phase 2a dosing extended to 52 weeks to enhance long-term safety, tolerability, and efficacy data
• Cash runway projected through at least Q1 2027

SAN DIEGO, March 20, 2025 (GLOBE NEWSWIRE) -- Skye Bioscience, Inc. (NASDAQ: SKYE) (“Skye” or the “Company”), a clinical stage biopharmaceutical company pioneering next-generation molecules that modulate G-protein-coupled receptors to treat obesity, overweight, and related conditions, today reported financial results for the fourth quarter and full year ended December 31, 2024, along with key accomplishments and upcoming milestones.

“Skye’s prime accomplishment in 2024 was the initiation and rapid advancement of its comprehensive Phase 2a clinical study of nimacimab, a novel and differentiated CB1 inhibitor,” said Punit Dhillon, President & CEO of Skye. “Maturation of the obesity therapeutics landscape, including expanding clinical evidence, M&A, and licensing, highlights the strategic importance of alternative mechanisms of action with attributes differentiated from incretins. We believe nimacimab’s product profile is well-positioned to potentially fulfill critical unmet needs in this rapidly evolving therapeutic area.

“Our team showed discipline in capital allocation and focus in executing the Company’s priorities. We surpassed our enrollment target ahead of schedule and have to-date executed the Phase 2a clinical plan on target and within our budget. We disclosed preclinical data in November 2024 which achieved significant dose-dependent weight loss, significant fat mass loss with lean mass preservation, and dose-dependent improvement in glucose tolerance. These outcomes are indicative of the potentially compelling attributes of Skye’s highly peripherally-restricted CB1 inhibitor. In 2025 and beyond we will continue to apply this discipline and focus. We are enthusiastic about our updated clinical development plan, which will dramatically speed up our path to important 52-week treatment data from this extension study. Robust data in 2025 and 2026 will be valuable to various stakeholders and inform our regulatory engagement for future studies and decision-making.”

Clinical Highlights: CBeyond™ Phase 2 Obesity Trial

• CBeyond™ trial completed enrollment of 136 patients: Study enrollment exceeded the initial target of 120, with data blinded through the completion of the 26-week treatment and 13-week follow-up period.
• Data Safety Monitoring Board reviews completed: Two independent data safety monitoring board reviews have been successfully completed.
• 16 US Clinical Sites: Welcomed a leading academic center of excellence in obesity as a clinical trial site during Q1 2025.
• Accelerated timeline for 26-week data to late Q3/early Q4 2025: Due to faster-than-anticipated enrollment the interim analysis has been removed and top line data is expected to be reported earlier than previously reported.
• Expansion of the CBeyond™ trial: To obtain 52 weeks of treatment data, the trial extension increases the originally planned 26 weeks of treatment to provide a longer-term assessment of safety, tolerability and efficacy. The protocol extension will provide for continued assessment of both the nimacimab monotherapy (primary endpoint) and the nimacimab/GLP-1 combination cohort (exploratory endpoint).
  

Research & Development Highlights

• Vital role and sufficiency of peripherally-targeted CB1 inhibition: Initial data from our diet-induced obesity model in mice released in November 2024 confirms that central CB1 inhibition is not required, and supports our hypothesis that nimacimab’s peripherally-targeted CB1 inhibition drives significant weight loss and improved metabolic parameters, consistent with the compound’s differentiated mechanism of action. An ongoing effort to characterize various attributes of nimacimab’s capabilities as the most peripherally restricted CB1 inhibitor is expected to result in further preclinical data outcomes.
• Broadening metabolic pathway understanding: Current studies are leveraging translational models to demonstrate nimacimab’s role in modulating hormones, inflammatory mediators, lipid metabolism, and glycemic control. We believe that additional data expected in the coming quarters may further clarify nimacimab’s potential across a range of metabolic disorders.
• Next-generation GPCR programs: The Company is advancing development of next-generation GPCR-targeting molecules designed to address diverse metabolic disorders.
  

Manufacturing Highlights

• Strengthening manufacturing: Advancing activities in collaboration with contract manufacturing organizations to prepare for future clinical demand for nimacimab and further optimize its potential for the treatment of obesity, overweight, and related metabolic disorders.
• Optimizing scale-up processes: Evaluating modifications to upstream and downstream manufacturing processes to improve product yield and establish a commercial manufacturing process that is reliable and repeatable for large-scale commercial production.
• Advancing toward monthly dosing: We are working to optimize nimacimab’s formulation and delivery to transition from weekly to monthly dosing to potentially improve patient experience, adherence, and commercial viability.
  

Corporate Highlights

• Chief Development Officer promotion: Skye recently promoted Tu Diep, to COO, recognizing his leadership throughout the Company. In this role, Mr. Diep is overseeing our development operations, CMC, corporate development and broader strategic execution.
• Strengthened the internal and external chemistry, manufacturing, and controls team: During 2024, Skye added to its team with seasoned individuals who bring significant experience in quality control and scale-up to nimacimab’s manufacturing processes.
• Resolved litigation matter: Skye settled its insurance litigation case and received $2 million in cash proceeds from its former D&O carrier in the fourth quarter of 2024.
  

Upcoming Milestones

• Q2 2025: Nimacimab preclinical data being presented at scientific/medical conferences.
• Q2 2025: Analyst event in conjunction with the Scientific Sessions of the American Diabetes Association (ADA) in June to introduce additional preclinical data, market research insights, and other aspects of the Company’s development program.
• Late Q3/early Q4 2025: Phase 2a CBeyond top-line data; full patient enrollment over 26 weeks of treatment and follow-up.
  

Fourth Quarter and Full Year 2024 Financial Results:

Balance Sheet Highlights:

• In January and March 2024, Skye closed two private investment in public equity transactions which collectively resulted in approximately $83.6 million in net proceeds.
• Cash and cash equivalents totaled $68.4 million on December 31, 2024. The Company expects its current capital to fund projected operations and key clinical milestones through at least Q1 2027, including completion of its Phase 2a study for nimacimab and Phase 2b manufacturing but excluding the Phase 2b clinical study or manufacturing activities necessary to supply a Phase 3 clinical study.
• Elimination of all related party balances, including the conversion of $5 million of debt to equity.
  

Operating Results:

• R&D Expenses:
  
  Research and development (R&D) expenses for the three months ended December 31, 2024, were $7.8 million, as compared to $1.6 million for the same period in 2023. The increase was primarily due to contracted clinical and manufacturing costs associated with our Phase 2 clinical trial for nimacimab in obesity and employee related benefits.
  
  R&D expenses for the year ended December 31, 2024, were $18.7 million, as compared to $5.8 million for the same period in 2023. The increase was primarily due to contracted clinical and manufacturing costs associated with our Phase 2 clinical trial for nimacimab in obesity. The remainder of the increase resulted from increases in discovery research efforts, consulting fees, employee benefits driven by increases in headcount, and general expenses.

• G&A Expenses:
  
  General and administrative (G&A) expenses for the three months ended December 31, 2024, were $4.6 million, as compared to $2.5 million for the same period in 2023. The increase was primarily related to non-cash incentive stock-based compensation, payroll, benefits and other employee costs, professional services including fees for tax, audit, legal services, financial advisory services, and other general business expenses.
  
  G&A expenses for the year ended December 31, 2024, were $17.7 million, as compared to $7.9 million for the same period in 2023. The increase was primarily related to non-cash incentive stock-based compensation, professional services including fees for tax, audit, legal services, financial advisory services, patent prosecution for nimacimab intellectual property, other general business expenses.

• Net Loss:
  
  Net loss for the three months ended December 31, 2024, totaled $9.7 million, with non-cash share-based compensation expense of $2.1 million, compared to $4.4 million for the year ended 2023, with non-cash share-based compensation expense of $0.6 million.
  
  Net loss for the year ended December 31, 2024, totaled $26.6 million, with non-cash share-based compensation expense of $8.3 million, compared to $37.6 million for the year ended 2023, with non-cash share-based compensation expense of $1.0 million. The primary reason for the significant decrease related to the acquisition of the nimacimab in-process research and development asset for $21.2 million during the year ended December 31, 2023, all of which was expensed upon acquisition. In addition, during 2024 we recognized a $4.2 million gain from the partial derecognition of contingent liabilities and a $2.0 million gain from insurance recoveries related to legal proceedings, $3.0 million in interest income and a gain of $1.4 million from the sale of real estate.
