Belite Bio Initiates Rolling Submission of New Drug Application to the U.S. Food and Drug Administration for Tinlarebant for the Treatment of Stargardt Disease

Belite expects to complete the new drug application submission in the second quarter of 2026
Rolling submission initiated under Breakthrough Therapy Designation

SAN DIEGO, April 21, 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 that it has initiated a rolling submission of an New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for tinlarebant, an investigational novel oral therapy for the treatment of Stargardt disease type 1 (STGD1), a rare, inherited retinal disorder caused by mutations in the ABCA4 gene. Tinlarebant has previously been granted Breakthrough Therapy Designation (BTD) by the FDA for STGD1, and the FDA has previously granted Belite approval for the rolling submission of the NDA. The Company expects to complete the NDA rolling submission in the second quarter of 2026.

“Stargardt disease is a devastating, progressive disease that typically begins in adolescence and leads to legal blindness in virtually all cases, severely impacting quality of life for those affected. The initiation of the NDA submission marks an important milestone for patients, caregivers, physicians, and the entire Stargardt community, as tinlarebant has the potential to become the first-ever approved treatment for Stargardt disease,” said Dr. Hendrik Scholl, Chief Medical Officer of Belite Bio. “I am proud of the data package that we are submitting to the FDA, including the transformative results from our Phase 3 DRAGON trial, and look forward to completing the NDA submission in the second quarter of this year.”

“I would like to extend my deepest gratitude to the patients, caregivers, investigators and all who participated in and supported our clinical trials, along with the entire Belite team, for helping us reach this important step,” said Dr. Tom Lin, Chairman and CEO of Belite Bio. “Our team has been working toward this milestone since we released our pivotal trial data demonstrating tinlarebant’s impact on slowing retinal degeneration. We are dedicated to bringing this potential treatment to patients in the U.S. and worldwide, and we are focused on continuing our commercialization preparation work, building out key teams including sales, market access, medical affairs, marketing, regulatory, and operations to ensure a seamless potential launch next year. We look forward to completing our NDA submission and working closely with the FDA during the review process.”

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 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.
