• Data from a 24-month Phase 2 trial in adolescents with STGD1 showed a sustained, lower atrophic lesion growth in Tinlarebant-treated subjects compared to ProgStar participants possessing similar baseline characteristics (aged ≤18 years) (p<0.001)
• In the Phase 2 trial, five of 12 subjects (42%) with known pathogenic ABCA4 mutations, no incident atrophic (DDAF) lesions were formed during the 24-month treatment period and no change in autofluorescent (QDAF) lesions was observed
• Company continues to expect interim analysis from the pivotal global Phase 3 trial of Tinlarebant in adolescent STGD1 subjects (“DRAGON”) in 4Q 2024
• Company to host conference call and webcast on Monday, August 12, 2024, at 4:30 p.m. EDT

SAN DIEGO, Aug. 09, 2024 (GLOBE NEWSWIRE) — Belite Bio, Inc (NASDAQ: BLTE) (“Belite” or the “Company”), a clinical-stage biopharmaceutical drug development company focused on advancing novel therapeutics targeting degenerative retinal diseases that have significant unmet medical needs, today announced its financial results for the second quarter ended June 30, 2024, and provided a general business update.

“We continued to make meaningful strides in advancing Tinlarebant this quarter. We initiated our DRAGON II trial in adolescent STGD1 patients and have completed the enrollment for its phase 1b portion, and notably, we received Sakigake designation in Japan, a testament to the groundbreaking potential of this drug and the unmet need it stands to address for people living with STGD1. In GA, we are approaching 200 patients enrolled in our pivotal Phase 3 trial,” said Dr. Tom Lin, Chairman and CEO of Belite Bio. “In the quarter, we also bolstered our balance sheet, having raised $25 million in gross proceeds in a registered direct offering in April. As we enter the second half of the year, we are well positioned to execute on key milestones and look forward to sharing interim analysis from our pivotal Phase 3 DRAGON trial in the fourth quarter.”

Second Quarter 2024 Business Highlights and Upcoming Milestones:

Clinical Highlights

Tinlarebant (LBS-008) is an oral, potent, once daily retinol binding protein 4 (RBP4) antagonist that decreases RBP4 levels in the blood and reduces vitamin A (retinol) delivery to the eye without disrupting systemic retinol delivery to other tissues. Vitamin A is critical to normal vision but can accumulate as toxic byproducts in individuals affected with STGD1 and GA (the advanced form of Dry AMD) leading to retinal cell death and loss of vision.

• Stargardt disease (STGD1): Accumulation of cytotoxic vitamin A byproducts (bisretinoids) has been implicated in the onset and progression of STGD1. Tinlarebant has been granted Fast Track Designation and Rare Pediatric Disease Designation in the U.S., Orphan Drug Designation in the U.S., Europe, and Japan, and Sakigake (Pioneer Drug) Designation in Japan for the treatment of STGD1.
  • DRAGON Trial: Ongoing, 24-month, randomized (2:1, active: placebo), double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in adolescent STGD1 subjects
    • Completed enrollment with 104 subjects in 11 countries
    • Primary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessed
    • Interim analysis expected in 4Q 2024
  • DRAGON II Trial: Combination of Phase 1b open-label trial to evaluate the pharmacokinetics and pharmacodynamics of Tinlarebant in Japanese adolescent STGD1 subjects and a Phase 2/3, double-masked, placebo-controlled, multicenter, trial in adolescent STGD1 subjects
    • Completed Phase 1b enrollment with six subjects in Japan
    • Company targeting approximately 60 subjects, aged 12 to 20 years old, including approximately 10 Japanese subjects, for enrollment in the Phase 2/3 portion of the trial with a 1:1 randomization, with data from Japanese subjects intended to facilitate future new drug application in Japan
    • Primary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessed
• Geographic Atrophy (GA): GA is a chronic degenerative disease of the retina that leads to blindness in the elderly. Accumulation of toxic vitamin A byproducts (bisretinoids) has been implicated in the progression of GA. There are currently no FDA approved, orally administered treatments for GA.
  • PHOENIX Trial: Ongoing, 24-month, randomized (2:1, active: placebo; n~430 subjects), double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in patients with GA
    • Primary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessed
    • Approximately 200 subjects have been enrolled as of August 9, 2024
    • Company expects to conduct interim analysis at the mid-point of the trial
