Belite Bio Reports First-Quarter 2024 Financial Results and Provides Corporate Update

• Tinlarebant is Belite Bio’s orally administered tablet intended to slow disease progression in patients affected with Stargardt Disease (STGD1) and Geographic Atrophy (GA) in advanced Dry Age-related Macular Degeneration (Dry AMD)

• Data from a 24-month Phase 2 trial in adolescent STGD1 subjects 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, 5 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 QDAF was observed

• A novel lesion size quantification method that can better detect atrophic lesions revealed 8 of 12 subjects with atrophic lesion involvement within the macula at baseline; growth of these lesions into the macula was halted during the second year

• Interim data from the pivotal global Phase 3 trial of Tinlarebant in adolescent STGD1 subjects (“DRAGON”) expected in 4Q 2024

• Initiated DRAGON II trial of Tinlarebant in adolescent STGD1 patients

• Pivotal global Phase 3 trial of Tinlarebant in GA subjects (“PHOENIX”) is ongoing

• Raised $25 million in gross proceeds in a registered direct offering in April 2024

• Conference Call and Webcast Tuesday, May 14, 2024, at 4:30 p.m. ET

SAN DIEGO, May 13, 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 first quarter ended March 31, 2024 and provided a general business update.

“It has been a strong start to 2024 with the initiation of the DRAGON II trial and the recent closing of our $25 million registered direct offering in April 2024,” said Dr. Tom Lin, Chairman and CEO of Belite Bio. “At the annual meeting of The Association for Research in Vision and Ophthalmology (ARVO), we announced additional analysis from our completed Phase 2 trial of Tinlarebant in adolescent STGD1 supporting its potential to slow or even halt disease progression. We are encouraged by these findings and look forward to building on this momentum as we continue to evaluate the potentially life-changing impact of this therapy in our ongoing STGD1 trials, DRAGON & DRAGON II, as well as in GA through our PHOENIX trial.”

First Quarter 2024 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 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 and Rare Pediatric Disease (RPD) designations by the U.S. Food and Drug Administration (FDA), and orphan drug designation (ODD) in the U.S., Europe, and Japan for STGD1. There are currently no FDA approved treatments for STGD1.
  • LBS-008-CT02 trial: Completed, open label, 24-month Phase 2 trial in adolescent STGD1 subjects and presented end of trial data at the AAO annual meeting in November 2023 and additional analysis at ARVO 2024
    • Tinlarebant was safe and well tolerated with no withdrawals due to adverse events
    • The 24-month data 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 5 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 QDAF was observed
    • A novel lesion size quantification method that can better detect atrophic lesions revealed 8 of 12 subjects with atrophic lesion involvement within the macula at baseline; growth of these lesions into the macula was halted during the second year
    • Visual acuity was stabilized in the majority of subjects during the trial with a mean loss of five letters following 24 months of treatment (a loss of <10 letters is not considered clinically significant)
    • In 6 subjects with prior bilateral BCVA loss (mean ~10 letters/year), mean BCVA loss over 24 months was 1.9 letters/year
    • Sibling subjects with identical ABCA4 mutations showed different rates of QDAF/DDAF lesion growth and BCVA loss
    • Additional analysis of visual acuity loss, genotypic profiles, and retinal imaging data provides further support for the potential of Tinlarebant to slow and potentially halt lesion growth

• • 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 data 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
    • Approximately 60 subjects, aged 12 to 20 years old, including approximately 10 Japanese subjects, are targeted for enrollment in the Phase 2/3 portion of the trial with a 1:1 randomization. The data from Japanese subjects is intended to facilitate future NDA applications in Japan
    • Initiated in Japan, the U.S., and the U.K.
    • Primary efficacy endpoint is slowing of atrophic lesion growth rate; safety and tolerability will also be assessed

• 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.
  • 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
    • Has enrolled 99 subjects
    • Interim data expected at mid-point of the trial

Corporate Highlights

• For the three months ended March 31, 2024, raised $12.5 million from the exercise of the warrants issued in the Follow-on Offering and ATM Offering.

G&A Expenses:

For the three months ended March 31, 2024, general and administrative expenses were $1.6 million compared to $1.2 million for the same period in 2023. The increase resulted primarily from an increase in share-based compensation granted in the third quarter of 2023.
