Belite Bio Announces Oral Presentation at the ASRS Annual Meeting Featuring Additional Positive Secondary Endpoint Data from the Phase 3 Trial of Tinlarebant in Stargardt Disease Type 1
Rhea-AI Summary
Belite Bio (NASDAQ: BLTE) reported additional positive secondary endpoint data from its Phase 3 DRAGON trial of tinlarebant in Stargardt disease type 1, presented at the ASRS 2026 Annual Meeting. Tinlarebant is described as the first therapeutic candidate to demonstrate clinical efficacy in this indication, having met the primary endpoint.
According to Belite Bio, quantitative autofluorescence, a marker of toxic bisretinoid accumulation, remained stable to slightly decreased (around 2%) at month 25 in tinlarebant-treated subjects, versus an approximately 20% increase with placebo. The 104‑patient, 2:1 randomized trial previously showed a statistically significant 35.7% reduction in retinal lesion growth versus placebo, with tinlarebant reported as well tolerated. The company also completed a New Drug Application for tinlarebant to the U.S. FDA.

SAN DIEGO, July 20, 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 additional, positive secondary endpoint data from its Phase 3 DRAGON trial of tinlarebant in Stargardt disease type 1 (STGD1). The findings, along with previously reported topline data, were delivered in an oral presentation at the American Society of Retina Specialists (ASRS) 2026 Annual Meeting on July 18, 2026, in Montréal, Canada.
Notably, the presentation reported that quantitative autofluorescence (qAF), a marker of toxic bisretinoid accumulation, showed a marked divergence between treatment groups. At month 25, in subjects treated with tinlarebant, qAF values remained stable to slightly decreased from baseline (approximately
“These additional results from the Phase 3 DRAGON trial continue to reinforce our conviction that tinlarebant has the potential to meaningfully slow retinal lesion growth in Stargardt disease. The data presented at ASRS builds on our foundational knowledge, adding to our understanding of tinlarebant's effect across secondary and supportive measures,” said Dr. Tom Lin, Chairman and CEO of Belite Bio. “We were pleased that these findings were shared at this retina’s flagship scientific meeting of the US and international community of retinal specialists as we advance through the regulatory review process and towards the potential approval of the first therapy for people living with STGD1.”
“These new secondary endpoint analyses reinforce the consistency of the treatment effect of tinlarebant. qAF values from baseline remained stable to slightly decreased, consistent with tinlarebant's mechanism of reducing the bisretinoid accumulation that drives disease progression,” said Dr. Hendrik Scholl, Chief Medical Officer of Belite Bio. “We believe these results deepen our understanding of tinlarebant and further support its continued clinical development and potential in Stargardt disease.”
About Tinlarebant (a/k/a LBS-008)
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 Stargardt disease type 1 (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, Japan, and Switzerland, and Sakigake Designation in Japan for the treatment of STGD1.
About Stargardt Disease Type 1 (STGD1)
STGD1 is the most common inherited macular dystrophy in both adults and children. The disease is caused by mutations in a retina-specific gene (ABCA4), which results in progressive accumulation of bisretinoids leading to retinal cell death and progressive loss of central vision. The fluorescent properties of bisretinoids and the development of high-resolution retinal imaging systems have helped ophthalmologists identify and monitor disease progression. Currently, there are no approved treatments for STGD1.
About Belite Bio
Belite Bio is a clinical-stage drug development company focused on advancing novel therapeutics targeting degenerative retinal diseases that have significant unmet medical needs, such as Stargardt disease type 1 (STGD1) and geographic atrophy (GA) in advanced dry age-related macular degeneration (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 and adult subjects with STGD1, which met its primary endpoint, and the drug is currently being evaluated in a Phase 2/3 trial (DRAGON II) in adolescent and adult subjects with STGD1 and a Phase 3 trial (PHOENIX) in subjects with GA.
