NCT ID: NCT06144918

Last Updated: 2026-01-14

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 56 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-11-09
• Study Completion Date: 2024-02-22

Brief Summary

The goal of this clinical trial is to test in patients with glaucoma and elevated pressure in the eye. The main questions it aims to answer are: • ability to lower pressure in the eye • safety in the eye and the body of patients with elevated pressure in the eye. Patients will be randomly given either:

• 0.5% (5 mg/mL) SBI-100 Ophthalmic Emulsion
• 1.0% (10 mg/mL) SBI-100 Ophthalmic Emulsion
• Placebo Ophthalmic Emulsion

Patients will be tested before starting and will have one drop of the product placed into each eye twice a day for 14 days, by the site and by the patient. At the end of the study, researchers will compare the groups to see if there is a change from before use of SBI-100 Ophthalmic Emulsion to the end of study.

Detailed Description

This is a multi-center, randomized, double-masked, placebo-controlled Phase 2 study to evaluate the ocular hypotensive efficacy, safety, and tolerability of SBI-100 Ophthalmic Emulsion after 14 days of binocular dosing, twice daily (BID).

There will be a 35-day screening period, including wash-out (if needed), followed by a visit on Day-1 to confirm eligibility. The first dose will be administered by the staff immediately after the (eligibility) 08:00 IOP measurement on Day 1, with subsequent study assessments up to 8 hours post-dose. The PM (evening) dose will be self-administered by the patient at home, approximately 12 hours after the AM (morning) dose. The patient will self-administer study treatment on Days 2 through 6 in the AM and PM. On Day 7, the patient will return to have the AM dose administered by site staff immediately after the 08:00 IOP measurement has been taken. Subsequent assessments will be performed in a similar fashion as Day 1 with study assessments up to 8 hours post-dose. Patient will self-administer the Day 7 PM dose and the AM and PM doses on Days 8 through 13. On Day 14, the patient will return to have the AM dose administered by site and assessments similar to that of Days 1 and 7, the patient may complete the final dose on Day 14 at the site approximately 12 hours after the AM dose and have end of study (EOS) procedures performed. Or the patient may choose to self-administer the Day 14 PM dose at home and return to the site within 2 days for EOS visit.IOP efficacy will be evaluated by Goldmann applanation tonometry. Safety/tolerability will be evaluated by review of ocular signs and symptoms through Best Corrected Visual Acuity (BCVA), ophthalmic assessments, ocular comfort patient-reported outcome (PRO), vital signs, and other standard safety measures

Diagnosis and main criteria for inclusion: Patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT)

Screening: up to 35 days, including wash-out from any topical pharmacological IOP-lowering therapies (if required) Treatment: 2 weeks (14 days) Follow up: Up to 2 days after the last dose on Day 14

Eligibility Criteria

Inclusion Criteria

1. At least 18 years of age or greater at time of informed consent.

2. Diagnosis of either primary open angle glaucoma (POAG) or ocular hypertension (OHT) in each eye.

3. Intraocular Pressure (IOP) Criteria:

1. If currently on an IOP-lowering therapy, patient is willing to withhold therapy according to study requirements, and in the opinion of the Investigator, can do so without significant risk.

2. If treatment naïve, Screening IOP is ≥ 21 and ≤ 36 mmHg in each eye, and in the opinion of the Investigator, is likely to be controlled on a single IOP-lowering therapy.

3. 08:00 Hour IOP is between 21 and 36 mmHg in each eye on Day-1 and Day 1.

4. Central corneal thickness between 480 and 620 μm at Screening in each eye.

5. Best correct visual acuity (BCVA) for distance equivalent to 20/100 or better in each eye at Screening and Day 1 (pre-dose).

Exclusion Criteria

Either eye:

1. Mean/Median intraocular pressure > 36 mmHg at Screening and/or any time prior to treatment administration.

2. Concurrent treatment for glaucoma requiring more than 2 topical therapies (either as 2 independent monotherapies or as fixed dose combination), oral IOP-lowering therapy and/or in the opinion of the Investigator cannot be controlled on a single IOP therapy.

3. Has planned ocular surgeries/procedures within the duration of the study.

1. Ocular trauma or surgery within 6 months

2. Ocular laser treatments within 3 months

3. In the opinion of the Investigator history or evidence of clinically significant ocular inflammation, including but not limited to blepharitis, conjunctivitis, etc.

4. History of recurrent ocular herpes (simplex or zoster)

5. Previous glaucoma intraocular surgery or glaucoma laser procedure and/or refractive surgery (e.g., radial keratotomy, PRK, SLT, LASIK, etc.) within 6 months

6. Ocular medication within 30 days prior, except for:

i. IOP-lowering therapies (washed-out per study requirements) ii. Lid scrubs iii. Artificial tears, gels and/or ointments to treat dry eye disease that in the opinion of the Investigator is not considered chronic use

5. Visual field loss, in the opinion of the Investigator, is functionally significant

General/Systemic:

1. Participation in any investigational study within 30 days of screening.

2. Known hypersensitivity or allergic reaction to cannabinoids, cannabis, sesame seed/oil or any component of the SBI-100 Ophthalmic Emulsion formulation and/or topical anesthetics.
