Frequently asked questions about BL1332

What is BL1332?

BL1332 is an investigational small molecule developed by Bausch + Lomb Corporation (ticker BLCO) as a topical ophthalmic solution. It is being studied for the management of ocular pain, including postoperative ocular pain. BL1332 is not approved and remains in clinical development.

What is BL1332 used for in postoperative ocular pain?

BL1332 is being evaluated for the management of postoperative ocular pain, including pain following photorefractive keratectomy. It is an investigational topical ophthalmic therapy and has not been approved for any indication. Clinical testing is ongoing to assess its potential in this setting.

What does BL1332 target?

BL1332 targets TRPV1, an ion channel. TRPV1 is a receptor involved in pain signaling, and BL1332 is designed as a small molecule topical ophthalmic solution directed at this target for ocular pain.

Who makes BL1332?

BL1332 is developed by Bausch + Lomb Corporation, which trades under the ticker BLCO. The company is responsible for the clinical development of the topical ophthalmic solution.

What phase is BL1332 in?

BL1332 is in Phase 1 clinical development. A Phase 1 study in healthy volunteers has been conducted, and a Phase 2 study in postoperative ocular pain is planned. BL1332 is investigational and has not been approved by the FDA.

What clinical trials is BL1332 in?

BL1332 has been studied in NCT06978244, a Phase 1 trial assessing safety, tolerability, and pharmacokinetics of ascending concentrations in healthy volunteers. A Phase 2 trial, NCT07412496, is planned to evaluate topical ocular BL1332 for postoperative ocular pain following photorefractive keratectomy.

Is BL1332 the same as BL1332 ophthalmic solution or Ocular BL1332 low dose?

Yes. BL1332 ophthalmic solution, Topical Ocular BL1332 low dose, and Ocular BL1332 low dose are alternative names for BL1332, the investigational topical ophthalmic small molecule developed by Bausch + Lomb Corporation for ocular pain.
