Aura Provides Phase 3 CoMpass Trial Completion Guidance: 2026 Enrollment Completion and Q4 2027 Topline Data Readout for the 15-Month Primary Endpoint Immune Profiling Data Reveal Bel-sar’s Potential to Convert ‘Cold’ to ‘Hot’ Tumors, Supporting a Frontline Therapy Across the Bladder Cancer Spectrum; Phase 1b/2 Trial is on Track for Data Mid-2026 BOSTON, Nov. 13, 2025 (GLOBE NEWSWIRE) -- Aura Biosciences, Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing precision therapies for solid tumors designed to preserve organ function, today reported financial results for the third quarter ended September 30, 2025, and provided recent business highlights. “In the third quarter, we remained focused on clinical execution in both our global Phase 3 CoMpass trial in early choroidal melanoma and our Phase 1b/2 trial in NMIBC,” said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura Biosciences. “Enrollment has taken longer than we expected in early choroidal melanoma due to the requirement to document active tumor growth prior to patient enrollment and other unique enrollment challenges with the first Phase 3 trial in this rare indication. In 2025, we implemented measures to address these operational challenges and have experienced improved enrollment in recent months. We believe we are now in a position to provide guidance regarding the topline data readout for the study.” “Our NMIBC trial remains on track, with data expected in mid-2026. Recently presented Phase 1 trial immune profiling data reinforce bel-sar’s distinct dual mechanism, driving focal anti-tumor immune activation. We believe these findings highlight bel-sar’s potential as a differentiated frontline, organ-preserving treatment to deliver durable responses across the bladder cancer spectrum and in other solid tumors.” Recent Pipeline Developments Early Choroidal Melanoma Ongoing Phase 3 CoMpass Trial: CoMpass is the first registration-enabling trial in early choroidal melanoma. The trial is a global, Phase 3, randomized trial evaluating bel-sar treatment against a sham control arm utilizing an enrichment strategy to enroll approximately 100 patients with documented tumor growth. We believe the study enrollment has been slower than expected due to the operational challenges of implementing the first Phase 3 trial in this rare indication across global sites and the requirement...
