Phase 3 Study of MELT-300 to Test Safety and Effectiveness for Sedation in Adults Having Cataract Surgery with Lens Replacement

What this Trial Is About

Researchers are evaluating the effects of MELT-300 on procedural sedation in adults undergoing cataract extraction with lens replacement CELR. This Phase 3 clinical trial aims to compare MELT-300 with a placebo and an active comparator, sublingual midazolam, to assess the contribution of ketamine in the combined drug product. The study focuses on the effectiveness and safety of MELT-300 during and after cataract surgery. Participants will be randomly assigned to one of three groups MELT-300 a sublingual tablet containing 3 mg midazolam and 50 mg ketamine, midazolam alone 3 mg sublingual tablet, or a placebo tablet. They will receive a single dose of the assigned medication approximately 30 minutes before surgery without food or water. The surgery will be performed under topical anesthesia, and the study medication effects will be assessed before, during, and after the procedure. Participants will be admitted on the day of surgery and monitored throughout. Researchers will assess sedation levels, the need for additional sedation or pain medication, and the ability to complete surgery. Safety will be tracked through adverse event monitoring, vital signs, and physical exams at baseline, during surgery, and up to three days after medication. The primary outcome measured is the percentage of participants achieving successful procedural sedation at various time points on the day of surgery.
