Belite Bio Completes Enrollment in the DRAGON II Clinical Trial of Tinlarebant for Stargardt Disease (STGD1)

SAN DIEGO, Jan. 27, 2026 (GLOBE NEWSWIRE) --Belite Bio, Inc (NASDAQ: BLTE) (“Belite Bio” or the “Company”), a clinical-stage drug development company focused on advancing novel therapeutics targeting degenerative retinal diseases that have significant unmet medical needs, today announced the completion of enrollment of 60 subjects, including 15 Japanese subjects, in the Phase 2/3 DRAGON II clinical trial evaluating tinlarebant for the treatment of Stargardt disease type 1 (STGD1).

DRAGON II clinical trial is a global, 24-month, randomized, double-masked, placebo-controlled study designed to evaluate the efficacy, safety, and tolerability of tinlarebant in adolescent patients with STGD1. The trial had a targeted enrollment of 60 adolescent subjects aged 12 to 20 years old across Japan, the United States, and the United Kingdom, with participants randomized 1:1 to receive either tinlarebant or placebo.

“We are pleased to complete enrollment in the DRAGON II clinical trial and sincerely thank the investigators, the adolescent participants, and their families who made this study possible,” said Dr. Tom Lin, Chairman and CEO of Belite Bio. “Their commitment reflects the strong engagement of the Stargardt disease community and supports our broader clinical development and commercialization efforts. Importantly, we remain on track to submit an NDA to the FDA for tinlarebant in the first half of 2026.”

“Completing enrollment in DRAGON II clinical trial represents continued execution of our tinlarebant clinical development program,” said Dr. Hendrik Scholl, Chief Medical Officer of Belite Bio. “We are pleased to have implemented a registration-enabling study that aligns with the requirements of the Japanese Pharmaceuticals and Medical Devices Agency (PMDA), supporting Belite Bio’s ability to pursue potential approval in Japan while advancing research for adolescents living with Stargardt disease globally.”

Tinlarebant is a novel oral therapy that is intended to reduce the accumulation of vitamin A-based toxins (known as bisretinoids) that cause retinal disease in STGD1 and also contribute to disease progression in geographic atrophy (GA), or advanced dry age-related macular degeneration (AMD). Bisretinoids are by-products of the visual cycle, which is dependent on the supply of vitamin A (retinol) to the eye. Tinlarebant works by reducing and maintaining levels of serum retinol binding protein 4 (RBP4), the sole carrier protein for retinol transport from the liver to the eye. By modulating the amount of retinol entering the eye, tinlarebant reduces the formation of bisretinoids. Tinlarebant has been granted Breakthrough Therapy Designation, Fast Track Designation, and Rare Pediatric Disease Designation in the U.S., Orphan Drug Designation in the U.S., Europe, and Japan, and Sakigake Designation in Japan for the treatment of STGD1.

Belite Bio is a clinical-stage drug development company focused on advancing novel therapeutics targeting degenerative retinal diseases that have significant unmet medical need, such as Stargardt disease type 1 (STGD1) and geographic atrophy (GA) in advanced dry AMD, in addition to specific metabolic diseases. Belite Bio’s lead candidate, tinlarebant, is an oral therapy intended to reduce the accumulation of bisretinoid toxins in the eye. The Company has completed a Phase 3 trial (DRAGON) in adolescent STGD1 subjects and is currently being evaluated in a Phase 2/3 trial (DRAGON II) in adolescent STGD1 subjects and a Phase 3 trial (PHOENIX) in subjects with GA.
