Skye Bioscience, Inc. (OTCQB: SKYE) (“Skye”), a pharmaceutical company developing proprietary, synthetic, cannabinoid-derived molecules to treat diseases with significant unmet need, issued today the following letter from Chief Executive Officer and Chair, Punit Dhillon.

Dear Shareholders, Colleagues and Collaborators,

I would like to thank you for your steadfast support and dedication in bringing our novel cannabinoid-based compounds to life as a potential new class of medicines.

Over the last 18 months, our singular mission has been to establish Skye’s novel cannabinoid-based compound for glaucoma as an important medicine for patients, recognizing that we are operating in a global pharmaceutical market that is changing rapidly and challenging us to stay one step ahead of the curve in terms of innovation. This is the urgency that drives us as we focus on consistently executing our goals until meaningful progress is achieved.

2021 represented an important year of fundamental progress for Skye. We further strengthened our team and work towards completing the preclinical development necessary to advance SBI-100 into the clinic. Our preclinical research to date gives us confidence that SBI-100 can be a promising drug candidate to treat glaucoma, the world’s leading cause of irreversible blindness.

The journey to prepare our lead product, SBI-100, for its next stage of development has not come without challenges, especially when set against the backdrop of a global pandemic. However, we are now on the verge of entering the most exciting and rewarding phase – becoming a clinical-stage company with a drug-disease combination that has the ability to produce a possibly significant and meaningful data outcome in a short and resource-efficient manner. The potential impact of our drug on glaucoma inspires us to also target a broader range of ocular diseases, pave the path for the adoption of novel cannabinoid compounds, and expand Skye’s drug pipeline.

Today, I am pleased to provide you with updates on our progress and insight into 2022 with a bold commitment to pursue every opportunity within our means to develop and expand an ophthalmology pipeline. We are preparing to make significant headway with the clinical development of SBI-100, the expansion of our R&D program, and the placement of resources and capabilities to support our escalating contributions toward disruptive innovation in the development of pharmaceutical cannabinoids.

SBI-100: Opportunity to Transform the Treatment of Glaucoma

At Skye, innovation lies at the center of our research and development process, and it drives our belief that targeting cannabinoid receptors has broad applicability to modify diseases in the eye. The basis of drug development at Skye rests on evidence that modulation of the endocannabinoid system (ECS) can provide therapeutic benefit for multiple diseases. By targeting ECS receptors such as CB1, CB2, PPAR-y, and GPR55, we can develop drugs to address an extensive set of pathologies in ophthalmology. For the ocular setting, this means showing improvement or modification of intraocular pressure, pain, inflammation, neovascularization, wound healing, neuroprotection, and fibrosis.

In 2021, we completed several important preclinical studies to demonstrate the safety and efficacy of SBI-100. In vitro safety studies included an epi-ocular irritation study that demonstrated little to no irritation induced by its eye drop formulation, plus genotoxicity studies that demonstrated SBI-100 caused no chromosomal damage or genetic mutations.

In vivo efficacy studies included a combination study that again demonstrated SBI-100’s ability to decrease intraocular pressure (IOP) to a greater degree and over a longer duration than the standard of care for the treatment of glaucoma as a standalone agent. The studies also demonstrated SBI-100's ability to further enhance the IOP-lowering benefit when co-administered with other classes of commercially available therapies, such as rho-kinase inhibitors. This data was presented at the American Association of Pharmaceutical Scientists (AAPS) and has been submitted to a peer-reviewed journal for publication consideration.

Additionally, I am pleased to share that we recently completed our good laboratory practice (GLP) toxicology study, which provides the final non-clinical dataset required for submission to the Australian Therapeutic Goods Administration to receive ethics approval, a necessary step before initiating our first-in-human trials with SBI-100. Before the end of 2021, we also completed a neuroprotection study to assess the potential of SBI-100 to protect retinal ganglion cells in an optic nerve crush model. We plan to share additional details from both studies upon a thorough review of the findings in the near term.

SBI-100 Entering the Clinic in 2022

We are fast approaching the initiation of our first-in-human Phase I study in the first half of 2022, with topline data expected in the third quarter of 2022 and the full data readout in the fourth quarter. Our Phase I study will evaluate the safety and tolerability of SBI-100 in healthy volunteers. The objective is to check an important box for regulatory authorities by demonstrating that our drug has minimal to no side effects in the eye and no unwanted systemic side effects from THC.

What is more significant, of course, is potentially demonstrating the IOP-reducing effects of SBI-100 in patients with glaucoma. We have therefore laid out a plan to initiate a Phase II study before the end of 2022. This study will be designed to evaluate the IOP-reducing effects of SBI-100 compared to both placebo control and an active control. It will be conducted in the US through an Investigational New Drug (IND) application, and I am pleased to share that in December 2021 we completed our pre-IND meeting with the U.S. Food and Drug Administration (FDA). We received valuable guidance from the FDA regarding the clinical development of SBI-100 in the U.S. and they agreed with the overall design of the proposed Phase II efficacy trial. This provides Skye with a clear path to move forward with an IND submission and, subject to approval, the initiation of its Phase II study, which we expect to begin in Q4 2022.

Cannabinoid Pharmaceutical Innovation Program

In the fourth quarter, we announced the launch of a new initiative to establish a proprietary screening platform to identify novel compounds with potential therapeutic benefit in ophthalmology and other diseases. This research with leading experts and academic collaborators around the world offers the prospect of increasing Skye’s development pipeline. It also raises the bar for the entire ophthalmology and cannabinoid research field, bringing a science-based proprietary approach to these potential medicines to benefit patients.

Expansion of Leadership Team

In the second half of 2021, we added substantial depth to our leadership team, adding vital roles and pertinent pharmaceuticals development experience, notably in the area of ophthalmology during a time of exponential growth.

Looking Forward in 2022

As with all diseases, the main driver for innovation in ophthalmology is unmet patient need. This is where Skye has an exceptional opportunity to be disruptive. At Skye, our innovation and development strategy and value creation plan are linked to the following milestones for 2022:

1.   Completion of a Phase I study to establish safety and tolerability of SBI-100 in humans
2.   Initiation of a robust placebo and active-controlled Phase II study for SBI-100 in glaucoma
3.   Development of a drug development platform to uncover novel molecules and mechanisms of action capable of modulating the endocannabinoid system to improve outcomes for a broad set of ophthalmic disease

2022 will undoubtedly be a transformative year for Skye. We have positioned the Company to execute on its ambitious agenda, transitioning from a preclinical to clinical-stage company and pursuing the compelling opportunities ahead of us.

As always, we thank you for your continued support and on behalf of the entire Skye team, we wish you a safe, healthy, and prosperous 2022.

Sincerely,
