Belite Bio, Inc has completed enrollment in the pivotal phase 3 PHOENIX trial. The 24-month, randomized, double-masked, placebo-controlled trial will evaluate the safety and tolerability of Tinlarebant and its potential to reduce atrophic lesion growth rate in patients diagnosed with geographic atrophy (GA) in dry age-related macular degeneration (AMD).1
The multicenter study is ongoing across sites in the United States, the United Kingdom, France, the Czech Republic, Switzerland, China, Taiwan, and Australia.1
In a company press release,1 Tom Lin, chairman and CEO of Belite Bio, noted, “Completing enrollment in the PHOENIX trial marks an important milestone for Belite Bio as we advance our lead candidate, Tinlarebant, for the treatment of geographic atrophy. This achievement brings us one step closer to evaluating the potential of Tinlarebant to slow atrophic lesion growth in this serious and progressive disease for which there are no approved oral treatments. There remains a significant unmet need for this patient population. We remain committed to advancing Tinlarebant through late-stage development and look forward to sharing interim results at the midpoint of the PHOENIX trial.”
Hendrik Scholl, MD, MA, chief medical officer at Belite Bio, also celebrated the global aspect of this trial and its potential to advance GA treatment options. He said, “We are pleased to announce the completion of enrollment in our pivotal clinical trial in geographic atrophy, a milestone that reflects strong global interest in our investigational therapy. The United States led enrollment by a significant margin, underscoring the appeal of a convenient, once-daily oral tablet compared [with] existing invasive treatment options.”1
“Geographic atrophy is a progressive and debilitating condition that can severely impact a person’s vision and therefore quality of life, yet treatment options remain limited,” said David Rhee, principal investigator at one of the top recruiting sites for the PHOENIX trial. “The PHOENIX study is designed to evaluate the efficacy of Tinlarebant in slowing the growth of atrophic lesions, a key clinical marker of disease progression. Completing enrollment is a meaningful step in advancing research for this patient population, and I look forward to seeing the results from this important study.”1
Previously, Ophthalmology Times reported on the DRAGON trial, noting the FDA had granted the agent a breakthrough therapy designation for the treatment of patients with Stargardt disease.2
Tinlarebant is an orally administered, once-daily tablet intended as an early intervention for maintaining the health and integrity of retinal tissues in patients with Stargardt disease type 1 (STGD1) and geographic atrophy (GA). Currently, there are no FDA-approved treatments for STGD1 and no approved orally administered treatments for GA. Therefore, if approved, Tinlarebant would be a novel oral therapeutic addressing an unmet medical need in STGD1 and GA. Tinlarebant has received a rare pediatric disease designation, fast track designation, and breakthrough therapy designation in the United States as well as an orphan drug designation in the United States, Europe, and Japan. The drug has also received sakigake (pioneer drug) designation in Japan for STGD1.1
