Evaluation of the Safety, Efficacy, Dose Response of the Bimatoprost Drug Ring System (BIM-DRS) in Pseudophakic Patients Diagnosed With Open Angle Glaucoma or Ocular Hypertension

June 8, 2026 updated by: SpyGlass Pharma, Inc.

Prospective, Multi-Center, Open-Label, Non-Randomized, Multi-Arm Study to Evaluate the Safety, Efficacy, and Dose Response of the Bimatoprost Drug Ring System (BIM-DRS) in Pseudophakic Patients Implanted With a Posterior Chamber Intraocular Lens (PC-IOL) and Diagnosed With Mild to Moderate Open-Angle Glaucoma (OAG) or Ocular Hypertension (OHT)

The goal of this clinical trial is to learn if two different doses of the SpyGlass Bimatoprost-Drug Ring System (BIM-DRS) work to treat adult pseudophakic patients with either glaucoma or ocular hypertension. The main question it aims to answer is:

Does the BIM-DRS lower the pressure inside the eye to treat glaucoma or ocular hypertension?

Researchers will compare two different doses of the BIM-DRS implanted either with a pre-existing commercially available monofocal intraocular lens (IOL) or concurrently with the SpyGlass IOL (IOL with silicone pads (no drug)).

Participants will:

  • Upon providing informed consent and successfully completing the screening visit, stop taking their IOP lowering medications in the eye to be treated.
  • Complete a baseline visit to further evaluate eligibility in the study eye.
  • Undergo surgery to implant the BIM-DRS (BIM-DRS and SpyGlass IOL for Cohorts 3 and 4). Only one eye of each participant will be treated.
  • Complete post-operative follow-up visits for evaluation at Day 1, Week 2, Week 6, Month 3, Month 6, Month 12, Month 18, Month 24, Month 30, and Month 36 (last study visit).
