Belite Bio Reports Second Quarter 2023 Operational Highlights and Financial Results

• Completed enrollment in pivotal Phase 3 “DRAGON” trial for Tinlarebant in adolescent Stargardt disease (“STGD1”) with 100 subjects enrolled across 11 countries worldwide
• First subject dosed with Tinlarebant in pivotal global Phase 3 “PHOENIX” trial in Geographic Atrophy (“GA”)
• Oral, once-daily Tinlarebant continues to be safe and well tolerated, slowing expansion of autofluorescence, reducing incident atrophic retinal lesion growth rate, and stabilizing visual acuity up to 18-months in Phase 2 STGD1 trial (“LBS-008-CT02”)
• Strengthened balance sheet with $30 million of gross proceeds from the underwritten public offering
• Final 2-year data of LBS-008-CT02 in STGD1 expected in Q4 2023 and interim Phase 3 safety and efficacy data from pivotal “DRAGON” trial expected in mid-2024
• Conference Call and Webcast Wednesday, August 9, 2023, at 4:30 p.m. ET

SAN DIEGO, Aug. 08, 2023 (GLOBE NEWSWIRE) -- Belite Bio, Inc (NASDAQ: BLTE) (“Belite” or the “Company”), a clinical stage biopharmaceutical drug development company focused on advancing novel therapeutics targeting retinal degenerative eye diseases which have significant unmet medical needs, today announced its financial results for the three months ended June 30, 2023 and provided a general business update.

“We continue to execute on key milestones and make significant progress across our late-stage program for Tinlarebant, an oral, once-daily treatment for retinal degenerative diseases including STGD1 and GA,” said Dr. Tom Lin, Belite’s Chairman and CEO. “We are pleased to have dosed the first subject in our pivotal PHOENIX trial for GA, in addition to completing enrollment in the pivotal DRAGON trial in adolescent STGD1. We have several potential inflection points over the next 12-18 months and anticipate the final 2-year data of LBS-008-CT02 will become available during the fourth quarter of this year, and the interim Phase 3 safety and efficacy data from our pivotal DRAGON trial will become available in mid-2024.”

Dr. Nathan L. Mata, Chief Scientific Officer of Belite Bio added, “The slowing of lesion growth and stabilization of visual acuity up to 18-months in the Phase 2 STGD1 trial with Tinlarebant is encouraging and reinforces the potential to treat other retinal degenerative diseases like GA. Oral vitamin A based approaches like fenretinide have previously demonstrated promise for the treatment of GA, but were limited to only a subset of patients due to the poor bioavailability and potency of fenretinide. We believe the chemical design of Tinlarebant overcomes the limited potency and bioavailability associated with fenretinide and offers the potential for enhanced efficacy outcomes across a broader patient population with a more selective targeting for improved safety.”

Second Quarter 2023 Business Highlights and Upcoming Milestones:

Clinical Highlights

Tinlarebant (LBS-008) is designed to be an oral, potent, once-daily retinol binding protein 4 (RBP4) antagonist that decreases RBP4 levels in the blood and selectively lowers 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 leading to retinal cell death and vision loss diseases such as STGD1 and GA, the advanced form of dry Age-Related Macular Degeneration (dry AMD).

• Stargardt disease (STGD1): Accumulation of cytotoxic bisretinoids has been implicated in the onset and progression of STGD1. Tinlarebant has been granted Fast Track and Rare Pediatric Disease (RPD) designations by the U.S. Food and Drug Administration (FDA), and orphan drug designation (ODD) in the U.S. and Europe for STGD1. There are currently no FDA-approved treatments for STGD1.
  
  
  • LBS-008-CT02 trial: Ongoing, open-label, 2-year Phase 2 trial in adolescent STGD1 subjects
    
    
    • 18-month efficacy and safety update (n = 12) at 2023 Association for Research in Vision and Ophthalmology (ARVO) demonstrated:
      
      
      • Tinlarebant continues to be safe and well tolerated
        
      • Nearly 60% of subjects (7 out of 12) had no incident atrophic retinal lesions as assessed by fundus autofluorescence (FAF) imaging
      • Tinlarebant stabilized visual acuity with no significant loss and no clinically significant changes in retinal thickness
      • When compared with participants from the Prospective Cohort Study of Childhood-Onset STGD1 by Georgiou et al., (2020), subjects in LBS-008-CT02 showed a reduced expansion of decreased autofluorescence (DAF) lesions from baseline to 18 months (0.69 ± 0.72 mm²/year versus 0.28 ± 0.28 mm²/year, respectively)⁽¹⁾. Areas of DAF represent the combined area of questionably decreased autofluorescence (QDAF) + definitely decreased autofluorescence (DDAF) lesions
      • When compared with ProgStar study participants ≤ 18 years old with only QDAF lesions at baseline, subjects in LBS-008-CT02 treated for up to 18 months showed⁽¹⁾:
        • Reduced expansion of DAF lesion size from baseline;
        • Reduced expansion in DDAF lesion size from baseline
          
          
          
          
  • Pivotal DRAGON trial: 2-year, randomized, double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in STGD1 subjects aged 12-20 years old:
    
    
    • Enrollment complete, with 100 subjects across 11 countries worldwide including sites in the U.S., the United Kingdom, Germany, Belgium, France, Switzerland, China, Hong Kong, Taiwan, Australia, and the Netherlands
    • Primary efficacy endpoint is slowing of lesion growth rate; safety and tolerability will also be assessed
    • Mid 2024: Interim efficacy and safety data expected
      

• Geographic Atrophy (GA): GA, the advanced form of dry AMD, 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.
  
  
  • Pivotal PHOENIX Trial: 2-year prospective, randomized (2:1, active:placebo, n ~430), double-masked, placebo-controlled, global, multi-center, Phase 3 trial in subjects with GA.
    
    
    • Primary efficacy endpoint is slowing of lesion growth rate; safety and tolerability will also be assessed
      
    • First subject has been dosed
    • Interim analysis expected at mid-point of the trial
      

Corporate Highlights

• Completed an underwritten public offering of American Depositary Shares (“ADSs”) and warrants for gross proceeds of $30 million
• Hosted two key opinion leader (KOL) events in May focused on a STGD1 disease overview and a discussion of Tinlarebant data in adolescent subjects:
  
  
  • Professor Hendrik Scholl, M.D. (Chairman of the Department of Ophthalmology, University of Basel) who discussed STGD1 overview and the 18-month data from the LBS-008-CT02 trial evaluating Tinlarebant for STGD1
  • Professor Michel Michaelides, M.D. (Professor of Ophthalmology at the UCL Institute of Ophthalmology) who discussed the progression of childhood-onset STGD1 and the relevance of Tinlarebant’s LBS-008-CT02 trial 18-month data
