Study Endpoints

Primary Endpoints

Percentage of Participants Achieving Successful Procedural Sedation
Preoperative (Day 1), Intraoperative (Day 1), and Postoperative (Day 1)

Successful procedural sedation is defined as achieving target sedation level (Ramsay Sedation Scale \[RSS\] level 2 or 3) by the start of surgery without need for rescue sedation medication, no requirement for intraoperative sedation medication, and able to complete the surgery (i.e. procedural sedation responder). The Ramsay Sedation Scale (RSS) was the first scale to be defined for the sedated participants and was designed as a test of arousability. The Ramsay Scale provides three levels of 'awake' states (score 1-3) and three levels of 'asleep' states (score 4-6). A score of 2 (participant is cooperative, orientated, and tranquil) best fits an optimum sedation level based on the criteria of calm, comfortable, communicative, and cooperative participants.

Mean Intraoperative Analgesia as Measured by the Numeric Pain Rating Scale
Intraoperatively on Day 1

The Numeric Pain Rating Scale (NPRS) is a segmented numeric version of the visual analog scale (VAS) in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of his/her pain. The 11-point numeric scale ranges from '0' representing one pain extreme (e.g. "no pain") to '10' representing the other pain extreme (e.g. "pain as bad as you can imagine" or "worst pain imaginable")

Frequently asked questions about MELT-300

What is MELT-300 used for?

MELT-300 is an investigational sublingual tablet being developed for sedation and intraocular ocular analgesia in patients undergoing cataract extraction with lens replacement (CELR). It is a small molecule being studied in the ophthalmology therapeutic area for cataract procedures.

What does MELT-300 target?

MELT-300 is a combination sublingual tablet containing midazolam and ketamine. Midazolam is a benzodiazepine that acts on GABA-A receptors to produce sedation, while ketamine is an NMDA receptor antagonist that provides analgesia and dissociative sedation.

Who makes MELT-300?

MELT-300 is being developed by Harrow, Inc., a pharmaceutical company traded on the NASDAQ under the ticker symbol HROW. The company is advancing the drug through clinical development for use in cataract surgery procedures.

What phase is MELT-300 in?

MELT-300 is currently in Phase 3 clinical development. A Phase 2 study has been completed, and a Phase 3 trial is actively recruiting participants to evaluate the drug's efficacy and safety for procedural sedation in cataract extraction with lens replacement.

What clinical trials is MELT-300 in?

MELT-300 has two clinical trials. NCT05133518 is a completed Phase 2 study with 338 participants, and NCT06383273 is an actively recruiting Phase 3 study with a target enrollment of 528 participants. Both trials are randomized, double-blind, placebo-controlled studies conducted in the United States.

Is MELT-300 the same as MELT-300 sublingual tablet?

Yes, MELT-300 is also known as MELT-300 sublingual tablet. The drug is administered as a sublingual tablet formulation, which is designed to dissolve under the tongue for rapid absorption during cataract surgery procedures.
