Belite Bio Receives Approval to Initiate Tinlarebant (LBS-008) Phase 3 Clinical Trial for Stargardt Disease in the Netherlands
- Tinlarebant (aka LBS-008) is Belite Bio’s orally administered tablet for early intervention to maintain the health of retinal tissue in Stargardt disease (STGD1) and Dry AMD patients
- There are currently no approved treatments for STGD1 and Dry AMD
- A 2-year Phase 2 trial in adolescent STGD1 and a global Phase 3 trial in adolescent STGD1 are ongoing
- The Phase 3 STGD1 trial named “DRAGON” is a Multi-center, Randomized, Double Masked, Placebo Controlled Study to Evaluate the Safety and Efficacy of TinlaRebant in the Treatment of StArGardt Disease in AdOlesceNt Subjects has commenced in the U.S., the United Kingdom, Germany, France, Belgium, Switzerland, China, Hong Kong, Taiwan, and Australia, with several patients already enrolled
- A 2-year Phase 3 trial in Dry AMD patients with geographic atrophy (GA) is expected to begin enrollment in the first half of 2023
- Tinlarebant, Belite Bio’s lead asset, has been granted Fast Track Designation and Rare Pediatric Disease Designation in the U.S., and Orphan Drug Designation in both the U.S. and Europe for STGD1
SAN DIEGO, Jan 11, 2023- Belite Bio, Inc (NASDAQ: BLTE) (“Belite” or the “Company”), a San Diego based clinical stage biopharmaceutical drug development company targeting currently untreatable eye diseases, today announces the approval of from The Central Committee on Research Involving Human Subjects to initiate the Phase 3 clinical trial of Tinlarebant (aka LBS-008) for STGD1 in the Netherlands.
The DRAGON trial is a phase 3, randomized, double-masked, placebo-controlled, global and multi-center study, designed to evaluate the safety and efficacy of Tinlarebant in adolescent STGD1 patients. To date, the Company has commenced the DRAGON trial in the U.S., the United Kingdom, Germany, France, Belgium, Switzerland, China, Hong Kong, Taiwan, and Australia. Approximately 60 patients are targeted for enrollment in this study with a 2:1 randomization (active:placebo).

About Tinlarebant (aka LBS-008)
Tinlarebant is a novel oral therapy intended as an early intervention to prevent the accumulation of vitamin A-based toxins (bisretinoids) that cause STGD1 and contribute to pathogenesis in Dry AMD. Bisretinoids are formed as by-products of vitamin A in the visual cycle. Tinlarebant works by reducing the level of serum RBP4, the carrier protein which transports the retinol to the eye. By modulating the amount of retinol entering the eye, Tinlarebant reduces the formation of bisretinoids to preserve the health of retinal tissues.
STGD1 is the most common inherited retinal dystrophy (causing blurring or loss of central vision) in both adults and children. The disease is caused by a dysfunctional retina-specific gene (ABCA4) which results in massive accumulation of toxic vitamin A byproducts (known as ‘bisretinoids’) in the retina leading to retinal cell death and progressive loss of central vision. The fluorescent properties of bisretinoids and the development of retinal imaging have helped ophthalmologists identify and monitor disease progression. Importantly, STGD1 and Dry AMD share a similar pathophysiology which is characterized by the excessive accumulation of cytotoxic bisretinoids, retinal cell death, and loss of vision. Vision loss occurs slowly, despite peripheral expansion of ‘dead retina’, until the disease reaches the center of the eye (the macula). There are currently no approved treatments available for STGD1.
Dry Age-related Macular Degeneration
Dry AMD is a leading cause of vision loss in the U.S. Dry AMD has a heterogenous etiology but shows a pathophysiology that is similar to that of STGD1 in which the excessive accumulation of cytotoxic bisretinoids leads to retinal cell death and loss of vision. There are an estimated 11 million patients with Dry AMD in the U.S. and over 196 million patients worldwide with an estimated global direct healthcare cost of US$255 billion. An advanced vision-threatening form of Dry AMD is Geographic Atrophy (GA), which is characterized by progressive atrophy of the retinal pigment epithelium and underlying choriocapillaris, followed by loss of photoreceptors within the retina, and ongoing visual impairment. Over 8 million people are affected worldwide with GA, which is approximately 20% of all individuals with AMD. The incidence of GA is expected to rise as the age-burden of developed countries is increasing. There are currently no approved treatments available for Dry AMD.
