SAN DIEGO, March 31, 2023 (GLOBE NEWSWIRE) — Belite Bio, Inc (NASDAQ: BLTE) (“Belite” or the “Company”), a San Diego based clinical stage biopharmaceutical drug development company targeting eye diseases with significant unmet medical needs, today announced its financial results for the full-year ended December 31, 2022 and provided a general business update.

“2022 was a transformative year for Belite, with achievements across key clinical and corporate milestones including the closing of our successful initial public offering, enrollment in over 11 countries for our pivotal Phase 3 DRAGON trial, and Phase 2 efficacy data reinforcing the potential for tinlarebant to slow down disease progression in Stargardt disease,” said Dr. Tom Lin, Belite’s Chairman and CEO. “As we look towards 2023, we remain focused on late-stage advancement of tinlarebant with continued enrollment in the DRAGON trial and the first patient of the Phase 3 PHOENIX trial in GA is expected to be enrolled during mid-year. We also expect to present the 18-month efficacy and safety data from our two-year Phase 2 trial in Stargardt disease during ARVO this year. With our balance sheet strengthened, we are well-positioned to execute across our near-term catalysts and work towards our mission of developing oral therapies for eye diseases with significant unmet medical needs.”

Clinical Highlights

Tinlarebant (LBS-008) is an oral, 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 as a means to potentially reduce the accumulation of toxic vitamin A byproducts within the eye leading to preservation of the retina. Vitamin A is critical for normal vision but it can be converted to toxic byproducts (bisretinoids) in degenerative retinal diseases such as STGD1 and GA leading to photoreceptor cell death and vision loss.

• 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.
  • Ongoing, open-label, 2-year Phase 2 trial in adolescent STGD1 subjects:
    • 13 subjects enrolled at clinical sites in Australia and Taiwan.
    • No atrophic retinal lesions in the 13 subjects at study start; only 1 subject developed bilateral retinal lesions (~0.44 mm² mean size) at the 12-month interval.
    • ARVO 2023, April 25: Expect to present 18-month efficacy and safety data.

• Pivotal DRAGON Trial: 2-year, randomized, double-masked, placebo-controlled, global, multi-center, pivotal Phase 3 trial in adolescent STGD1 subjects:
  • Trial initiated in the U.S., the United Kingdom, Germany, Belgium, France, Switzerland, China, Hong Kong, Taiwan, Australia, and the Netherlands, with 42 subjects enrolled; at least 90 subjects are targeted for enrollment.
  • Upper age range for enrollment increased from 18 to 20 years.
  • 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, an advanced form of Dry Age-Related Macular Degeneration (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: initiated; a 2-year prospective, randomized (2:1, active:placebo, n ~430 subjects), double-masked, placebo-controlled, global, multi-center, Phase 3 trial in patients with GA.
  • Primary efficacy endpoint is slowing of lesion growth rate; safety and tolerability will also be assessed.
  • Interim analysis expected at mid-point of the study.
  • Mid 2023: Enrollment of first patient in pivotal Phase 3 PHOENIX trial expected

Corporate Highlights

• Completed initial public offering in April 2022. Belite Bio (NASDAQ: BLTE) became listed on Nasdaq and raised net proceeds of approximately $38.0 million including the overallotment. The Company expects to use the net proceeds to fund the Phase 3 clinical trial of Tinlarebant for STGD1 and GA, working capital and other general corporate purposes.
