Aura Biosciences Announces Positive Interim Phase 2 Safety and Efficacy Data of Belzupacap Sarotalocan (Bel-sar) for the First-Line Treatment of Patients with Early-Stage Choroidal Melanoma with Suprachoroidal Administration at the Macula Society 46th Annual Meeting
“The data presented today with an average of nine months of follow up for patients treated with three cycles of therapy, show an excellent response to the therapy with 89-100% tumor control. In addition, the safety profile to date has been favorable with only one patient losing visual acuity and no treatment-related SAEs or significant AEs, which is encouraging given that the majority of these patients had tumors close to the fovea or optic disk and would have likely experienced severe and irreversible vision loss with the current standard of care with radiotherapy,” said Dr.
“We are excited with the interim efficacy data of the Phase 2 study which strongly supports the assumptions for the success of the global Phase 3 trial,” said Dr.

Updated Safety and Efficacy Data from the Ongoing Phase 2 Trial with
This Phase 2 trial (NCT04417530) is assessing the safety and preliminary efficacy of single- and multiple ascending-doses of bel-sar up to three cycles of treatment via SC administration for the first-line treatment of early-stage choroidal melanoma. A total of 20 adult patients have been enrolled in the trial including the single dose Cohorts 1-3 (n=6) and multiple dose escalation Cohorts 4-6 (n=14). Cohorts 5 and 6 received up to three cycles of therapy, which was considered the therapeutic regimen for evaluation. One patient in Cohort 5 (n=3) received two cycles of therapy and two patients in Cohort 5 received three cycles of therapy (40 μg/dose). All patients from Cohort 6 (n=8) were assigned to receive three cycles of therapy at the highest dose (80 μg/dose). One patient from Cohort 6, who discontinued after one cycle due to unrelated serious adverse events (SAEs), is not included. All patients in Cohorts 5 and 6 had active growth at study entry, as an enrichment strategy to evaluate preliminary efficacy. This group of patients with active growth treated at the therapeutic regimen of three cycles was evaluated for tumor growth rate, tumor control, and visual acuity preservation as the defined clinical endpoints to evaluate preliminary efficacy. The results, with an average of nine months of follow up in patients who received three cycles of therapy in Cohorts 5 and 6, and who match the criteria for the planned global Phase 3 trial, showed a statistically significant reduction in the tumor growth rate (-0.289 mm/yr, p = <0.0001) compared to each patient’s documented growth rate at study entry, and a 100% (8/8) tumor control rate. In addition, the visual acuity preservation rate was 88% (7/8) in these cohorts, with the majority of patients being at high-risk for vision loss with tumors close to fovea or optic disk. The overall tolerability profile of bel-sar was generally favorable, with no dose-limiting toxicities, treatment-related SAEs or significant AEs reported as of
