SBI-100 OPHTHALMIC EMULSION: RECENT DEVELOPMENTS


 

SBI-100 is a pro-drug of Tetrahydrocannabinol (THC), which is being evaluated as a topical agent in ophthalmic suspension form.

The agent could be useful in the treatment of glaucoma and ocular hypertension.

The agent has undergone a Phase 1 study with 2 cohorts each of 8 patients.

Skye Bioscience, Inc., the parent company, has received positive recommendation following a pre-specified data review by the safety review committee (SRC). The SRC has recommended that the trial continue without modification. The company shall be recruiting the third cohort soon.

In nonclinical studies, Skye’s SBI-100 Ophthalmic Emulsion demonstrated a greater and longer-lasting reduction of IOP compared to leading commercialized drugs in the glaucoma market. These studies also demonstrated:

  • SBI-100 Ophthalmic Emulsion is better at penetrating various compartments of the eye than natural THC
  • THC in an ex vivo model demonstrated a reduction of biomarkers related to fibrosis and inflammation in conjunction with lowering of IOP, supporting a multimodal mechanism of action

Previous preclinical studies have shown the potential for THC to also provide neuroprotective benefit, which may be especially important to patients with glaucoma who are experiencing disease progression with normal IOP levels.

One of the major drawbacks of previous studies concerning the use of THC for glaucoma was that they relied on inhalation or ingestion of THC. These systemic routes of drug administration cause negative side effects like psychotropic changes and potentially decreasing blood pressure, which resulted in the American Academy of Ophthalmology determining that the adverse effects of systemic cannabis administration/consumption outweighed its therapeutic benefit.

Skye has chemically modified THC to create a unique synthetic molecule with the intent to safely realize the known positive effects of THC. The molecule enables enhanced local delivery in the eye, reduced systemic side effects, and the potential for neuroprotection for the treatment of ocular diseases.



HIGHLIGHTS:

SBI-100 OE is a cannabinoid receptor type 1 (CB1R) agonist delivered topically into the eye. It is a synthetic cannabinoid derivative to treat glaucoma and ocular hypertension. SBI-100 OE possesses 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.”
