The safety review committee (SRC) has reviewed the data from the fourth cohort of Skye Bioscience’s Phase I clinical trial of SBI-100 Ophthalmic Emulsion (OE) and has given approval to proceed with the fifth cohort.

Patients of the first, second, and third cohorts who received SBI-100 in the Phase I trial reported no adverse events.

Mild to moderate drug-related adverse events, which are typically associated with topical eye treatments, were reported across all cohorts.

A total of 24 subjects were enrolled in the three cohorts. Out of the total, 18 subjects received a single dose of 0.5%, 1%, and 2% SBI-100 OE in their respective single ascending dose (SAD) arm studies, and the remaining received a placebo.

In the first cohort’s multiple ascending dose (MAD) arm study, six healthy subjects were treated with a single dose of 0.5% SBI-100 OE in the morning and evening for five days while the remaining received a placebo.

For a total of seven days, including the five days of dosing, subjects were monitored at the clinical research unit in Adelaide, Australia.

Fifth and sixth cohort subjects are expected to receive 1% and 2% SBI-100 OE this month and later next month, respectively.

SBI-100 OE is formulated as an eye drop using a propriety nanoemulsion. It targets the CB1 receptor, which plays an important role in managing intraocular pressure associated with glaucoma, a leading cause of irreversible blindness.

Results were found to be favourable in preclinical studies of SBI-100 OE as a single agent and along with standard of care (SOC) glaucoma drugs, compared to SOC alone and other combinations.
