Frequently asked questions about Bimatoprost System

What is Bimatoprost System used for in cataract?

Bimatoprost System is an investigational small molecule being developed for use in cataract surgery. It is designed to be used in combination with the SpyGlass Intraocular Lens (IOL) to treat cataract, glaucoma, and ocular hypertension. The drug is currently in Phase 3 clinical development.

What does Bimatoprost System target?

Bimatoprost System targets the prostaglandin F2-alpha receptor (PTGFR), acting as an agonist. This mechanism is intended to lower intraocular pressure in patients undergoing cataract surgery with the SpyGlass Intraocular Lens. The drug is being evaluated for its ability to manage glaucoma and ocular hypertension in this setting.

Who makes Bimatoprost System?

Bimatoprost System is being developed by SpyGlass Pharma, Inc., a company traded under the ticker symbol SGP. The company is conducting clinical trials to evaluate the drug's safety and efficacy in combination with its SpyGlass Intraocular Lens for patients with cataract, glaucoma, and ocular hypertension.

What phase is Bimatoprost System in?

Bimatoprost System is in Phase 3 clinical development. It is an investigational drug, not yet approved by regulatory authorities. The Phase 3 program includes two active trials, Rhine and Rhone, which are recruiting patients to compare the Bimatoprost Implant System with the SpyGlass IOL against timolol ophthalmic solution.

What clinical trials is Bimatoprost System in?

Bimatoprost System is being studied in three active clinical trials. NCT06120842 is a Phase 1 study with 201 participants. NCT07218783 (Rhine) and NCT07218796 (Rhone) are Phase 3 trials, each enrolling 400 participants. All trials are active in the United States and compare the implant system with timolol ophthalmic solution.

Is Bimatoprost System the same as Bimatoprost Implant System?

Yes, Bimatoprost System is also known as Bimatoprost Implant System, including the High Dose version. These names refer to the same investigational drug-device combination being developed by SpyGlass Pharma for use with the SpyGlass Intraocular Lens in cataract surgery patients with glaucoma or ocular hypertension.
