Skye Bioscience Announces $50.25 Million Private Placement Equity Financing

San Diego, California--(Newsfile Corp. - January 29, 2024) - Skye Bioscience, Inc. (OTCQB: SKYE) ("the Company"), a clinical stage biotechnology company focused on the discovery, development and commercialization of novel classes of therapeutic drugs that modulate the endocannabinoid system, today announced that it has entered into a securities purchase agreement for the sale of (i) 11,822,124 shares of its common stock at $2.305 per share and (ii) to certain investors, in lieu of common stock, pre-funded warrants to purchase up to 9,978,739 shares of common stock at a price of $2.3049 per pre-funded warrant in a private placement (the "PIPE") to certain qualified institutional buyers. The pre-funded warrants will have an exercise price of $0.001 per share, will be exercisable immediately and will be exercisable until exercised in full. Gross proceeds from the PIPE are expected to be $50.25 million, before deducting any placement agent fees and offering-related expenses. The PIPE financing is expected to close on January 31, 2024, subject to the satisfaction of customary closing conditions.

The PIPE financing was co-led by a life sciences-focused investor and 5AM Ventures, with participation from Ally Bridge Group, Sphera Healthcare, Altium Capital, Driehaus Capital Management and other institutional investors.

Piper Sandler is acting as the lead placement agent and Oppenheimer & Co. is acting as a placement agent for the PIPE financing.

The Company expects the PIPE financing net proceeds to fund its operations into early 2026 through a set of key milestones and operations encompassing:

• Phase 2 clinical trial for nimacimab in obesity: anticipating starting mid-year 2024; interim data expected in Q1 2025; preliminary topline data expected in 2025
• Phase 2a clinical trial for SBI-100 Ophthalmic Emulsion ("OE") in glaucoma and ocular hypertension: currently enrolling; interim data expected Q1 2024; preliminary topline data Q2 2024
• Phase 2b trial of SBI-100 OE for glaucoma and ocular hypertension: anticipating starting H2 2024; preliminary topline data expected in 2025
• Ongoing R&D, general corporate purposes and working capital.

As an update to its previously announced clinical development plans, Skye is planning a Phase 2 trial that will randomize approximately 200 obese patients into four equal-sized arms in which they will be administered either 1) nimacimab (200 mg), 2) GLP-1R agonist (2.4 mg), 3) a combination of nimacimab and GLP-1R agonist, or 4) placebo for 26 weeks with a 12-week follow-up. The primary endpoint will be percent change in weight from baseline at week 26. Secondary endpoints include safety and tolerability, change in waist circumference, change in body composition, change in fasting triglycerides and cholesterol, and change in A1c (a measure of blood sugar). This planned Phase 2 clinical trial design is not finalized and remains subject to change based on further input from advisors and the U.S. FDA.

"CB1-modulating therapies have potential to meaningfully impact the treatment of obesity and glaucoma, and Skye's technology and development plans have resonated with a strong syndicate of specialist life science investors and resulted in funding through multiple Phase 2 catalysts," said Punit Dhillon, CEO and Chair of Skye. "We appreciate the engagement of the new investors and ongoing support of our existing investors who have enabled us to accelerate our programs and enhance Skye's value proposition.

He added: "As the obesity market witnesses remarkable clinical and commercial outcomes with new drugs, it is revealing opportunities for mechanisms that complement weight loss beyond incretin-based appetite suppression such as promoting loss of fat tissue while preserving lean mass, as well as enhancing leptin and insulin sensitivity. The merit of peripheral CB1 inhibition to possibly enable such outcomes is scientifically well-validated and nimacimab, as a negative allosteric modulating antibody, stands out with its distinguishing characteristics within this mechanistic category. This funding allows us to pursue a high-impact clinical strategy for nimacimab and places us among the most advanced programs evaluating a peripheral CB1 inhibitor in comparison to and in combination with a GLP-1 drug for obesity.

"We also look forward to near-term data from our currently-enrolling Phase 2a trial of SBI-100 OE, which showed positive efficacy signals in a subset of patients in our Phase 1 trial, and advancing a Phase 2b trial comparing SBI-100 OE against a standard of care drug. Key opinion leaders have strongly indicated the need for an alternative class of intraocular pressure-lowering drug, and with only one new class commercialized in the last roughly 25 years (Rhopressa, 2017), there is a compelling opportunity for SBI-100 OE, which, like nimacimab, involves a mechanism of action with compelling prior evidence of utility and an excellent safety profile in human studies to date."
