Frequently asked questions about Tinlarebant

What is Tinlarebant used for?

Tinlarebant is an investigational small molecule being developed for Stargardt Disease 1 (STGD1), a form of juvenile macular degeneration, and for Geographic Atrophy, a late-stage form of dry age-related macular degeneration. It is also being studied in healthy volunteers for pharmacokinetic purposes. Tinlarebant is not yet approved and remains in clinical development.

How does Tinlarebant work?

Tinlarebant is a small molecule designed to target the visual cycle. It works by reducing the accumulation of toxic byproducts in the retina that contribute to retinal degeneration in Stargardt Disease and Geographic Atrophy. This mechanism aims to slow disease progression by limiting the formation of these harmful compounds.

Who is developing Tinlarebant?

Tinlarebant is being developed by Belite Bio, Inc, a biopharmaceutical company traded on the NASDAQ under the ticker symbol BLTE. The company is conducting clinical trials for Tinlarebant in Stargardt Disease and Geographic Atrophy.

What phase is Tinlarebant in?

Tinlarebant is currently in Phase 3 clinical development for both Stargardt Disease 1 and Geographic Atrophy. It has received several FDA designations, including Breakthrough Therapy, Fast Track, Orphan Drug, Rare Pediatric Disease, and Priority Review, reflecting its investigational status.

What clinical trials is Tinlarebant in?

Tinlarebant has been studied in multiple trials. NCT05244304 is a completed Phase 3 placebo-controlled study in adolescent Stargardt Disease. NCT05949593 is an active Phase 3 trial in Geographic Atrophy. NCT05266014 is a completed Phase 1 dose-finding study in Stargardt Disease, and NCT05667688 is a completed Phase 1 study in healthy volunteers.

Is Tinlarebant the same as LBS-008?

Yes, Tinlarebant is also known as LBS-008. In clinical trials, the drug has been referred to by both names, with LBS-008 appearing in study titles for pharmacokinetic and pharmacodynamic research. Both names refer to the same investigational compound developed by Belite Bio.
