A Phase 2 Study of RCI001 Ophthalmic Solution in Participants With Dry Eye Disease

1. juni 2026 opdateret af: Rudacure

A Phase 2, Multi-center, Randomized, Double-Masked and Placebo-Controlled Study Evaluating the Efficacy and Safety of RCI001 Ophthalmic Solution Compared to Placebo in Subjects With Dry Eye

This is a Phase 2 clinical study designed to evaluate the safety and efficacy of 0.25% RCI001 Ophthalmic Solution compared with placebo in participants with dry eye disease.

The study will enroll adults with dry eye disease. After a 2-week run-in period with placebo ophthalmic solution, eligible participants will be randomly assigned to receive either 0.25% RCI001 Ophthalmic Solution or placebo ophthalmic solution in both eyes for 4 weeks. Study treatment will be administered either twice daily or four times daily, depending on the assigned dosing regimen.

The main purpose of the study is to determine whether RCI001 improves the signs and symptoms of dry eye disease compared with placebo. The primary assessments include total corneal fluorescein staining and ocular discomfort at Day 28. Safety will be assessed through eye examinations, visual acuity, intraocular pressure, drop comfort, and adverse event monitoring.

Detaljeret beskrivelse

This is a multi-center, randomized, double-masked, placebo-controlled Phase 2 study evaluating 0.25% RCI001 Ophthalmic Solution in participants with dry eye disease.

The study will include approximately 6 weeks of participation for each participant, consisting of a 2-week run-in period followed by a 4-week treatment period. Approximately 400 participants are expected to be screened, and approximately 200 eligible participants will be randomized, with approximately 50 participants assigned to each treatment group.

During the run-in period, participants who qualify at screening will receive placebo ophthalmic solution in both eyes according to either a twice-daily or four-times-daily dosing regimen. At the end of the run-in period, eligible participants will be randomized to continue the same dosing frequency and receive either 0.25% RCI001 Ophthalmic Solution or placebo ophthalmic solution bilaterally for 4 weeks.

The four treatment groups are:

0.25% RCI001 Ophthalmic Solution twice daily; placebo ophthalmic solution twice daily; 0.25% RCI001 Ophthalmic Solution four times daily; and placebo ophthalmic solution four times daily.

The study will include four scheduled visits: screening at Day -14, baseline/randomization at Day 1, follow-up at Day 14, and end-of-treatment/study exit at Day 28. Controlled Adverse Environment (CAE) assessments will be used as part of the study procedures.

The primary efficacy endpoints are total corneal fluorescein staining and ocular discomfort assessed before CAE exposure at Day 28. Secondary efficacy assessments include additional ocular staining measures, conjunctival redness, Schirmer's test, tear film break-up time, Ocular Surface Disease Index, ocular discomfort scores, visual analog scale symptoms, and daily symptom diary data.

Safety assessments include visual acuity, slit-lamp biomicroscopy, drop comfort, adverse event monitoring, intraocular pressure, and dilated fundoscopy. The study is designed to compare RCI001 with the corresponding placebo dosing regimen and to evaluate the optimal dosing frequency of RCI001 in the treatment of the signs and symptoms of dry eye disease.

Acceptable methods include hormonal contraceptives, mechanical contraception with spermicide and a barrier method, intrauterine device, or surgical sterilization of partner. For non-sexually active females, abstinence may be regarded as adequate; however, if the participant becomes sexually active during the study, she must agree to use adequate birth control for the remainder of the study.
  8. Known allergy and/or sensitivity to the test article or its components.
  9. Any condition or situation that, in the investigator's opinion, may put the participant at significant risk, may confound study results, or may interfere significantly with participation in the study.
