Skye Bioscience, Inc. (OTCQB: SKYE) (“Skye” or the “Company”), a pharmaceutical company developing a proprietary, synthetic cannabinoid derivative to treat glaucoma, has been advised by its contract manufacturer (“CMO”) of its Phase 1 clinical trial material that a now-resolved cyber-attack on the CMO’s computer systems as well as a planned annual maintenance shutdown will result in a delay in completing production of Skye’s Phase 1 drug to the beginning of September. Skye now expects to initiate enrollment of its Phase 1 clinical study in Q4 2022, report preliminary topline data in early Q1 2023, and report final data in Q2 2023.

Skye’s SBI-100 Ophthalmic Emulsion (“SBI-100 OE”) had most recently been scheduled for production and fill in the first week of July. While the CMO has sufficiently recovered from the recent cyber-attack, planned annual facility maintenance could not be rescheduled. The maintenance schedule has been accelerated and will be conducted through August 30.  Skye’s SBI-100 product is now planned to be produced and filled in the first week of September, with required drug quality testing completed by the first half of October.

“The unpredictable events that have detrimentally affected our production schedule have been frustrating, but we are confident in the renewed commitment of our contract manufacturer to produce our clinical trial material and the schedule to start our planned study,” said Punit Dhillon, CEO and Chair of Skye. “Securing approval for the Australian Human Research Ethics Committee at the end of June was a vital factor to move our Phase 1 forward. While the delay in the Phase 1 is not a welcomed outcome, we are pleased that we continue to progress on the logistics that move us toward enrollment and dosing of the first cohort of patients.

“As we previously noted, we are in parallel progressing our Phase 2 clinical development plan. In our preliminary meeting last winter with the FDA to discuss our planned Investigational New Drug (“IND”) application, the FDA confirmed that, as is standard practice with all ophthalmology clinical studies, it would accept from Skye nonclinical toxicology data for review and approval of its IND and Phase 2 protocol rather than requiring Phase 1 safety data. The Phase 1 study outcome will provide us the benefit of safety and tolerability data of SBI-100 OE but is not a gating factor to initiate Phase 2. We continue to look forward to obtaining Phase 1 data but concurrently developing our clinical plans with the expectation that we can report Phase 2 by year-end 2023.”

About SBI-100 Ophthalmic Emulsion
Increased intraocular pressure (IOP) is a key risk factor in the progression of glaucoma. The first observations that consuming cannabis lowered IOP in humans took place in the early 1970s, which led to a significant amount of research on the effects of cannabinoids in the eye. Independent studies demonstrated that activation of the cannabinoid receptor-type 1 (CB1R) in ocular tissue mediates IOP-lowering. However, no cannabinoid-related drug has been approved for clinical use in the eye due primarily to the shortcomings of current delivery methods of CB1R agonists to the eye in a therapeutically beneficial dose. When cannabinoids are administered systemically, they can lower IOP but also result in undesirable psychotropic effects. Alternatively, extracted natural cannabinoids delivered topically as an eye drop do not penetrate ocular tissue well enough to effectively lower IOP due to the lipophilic, or oily, properties of natural cannabinoids and the aqueous, or watery, surface of the eye. 

To address these challenges, Skye developed SBI-100 OE, a proprietary, synthetic cannabinoid derivative possessing a novel molecular structure and formulation that was rationally designed to enable better penetration of ocular tissue and effective topical delivery of a CB1R agonist. In preclinical studies involving three different species, a nanoemulsion formulation of the drug applied topically to the eye resulted in enhanced therapeutic efficacy and duration of response in lowering IOP. Importantly, these studies also demonstrated advantages compared to today’s standard of care and, if clinically validated in subsequent efficacy studies, may provide a suitable therapeutic window to be a new class of medicine for glaucoma.
