Aura Biosciences Reports Positive Phase 2 End of Study Results Evaluating Bel-sar as a First-
Line Treatment for Early-Stage Choroidal Melanoma
Bel-sar Demonstrated 80% Tumor Control Rate, 90% Visual Acuity Preservation, and a Highly Favorable
Safety Profile
Aura to
Host a Virtual Ocular Oncology Investor Event Featuring Key Opinion Leaders Today at 8:00 am ET
BOSTON, MA September 12, 2024
Aura Biosciences, Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing precision therapies for solid tumors designed to preserve organ function, today announced positive Phase 2 end of
study results evaluating bel-sar (AU-011) for the first-line treatment of early-stage choroidal melanoma (CM), a vision and life-threatening ocular cancer. The results were presented at The Retina Society
Annual Meeting, on Thursday, September 12, 2024, in Lisbon, Portugal.
The Phase 2 study (NCT04417530) is an open-label, ascending single and
repeat dose escalation trial in patients with early-stage CM (small CM and indeterminate lesions) designed to evaluate the safety, tolerability, and efficacy of up to three cycles of bel-sar treatment. The trial included both single and multiple
ascending dose cohorts, with a total of 22 patients enrolled. Patients were closely monitored over a twelve-month follow-up period to assess tumor control, visual acuity preservation, and tumor growth rate.
Tumor Control and Visual Acuity Preservation
The
Phase 2 results demonstrated that bel-sar achieved an 80% tumor control rate (n=8/10) among Phase 3-eligible patients who received the therapeutic regimen, with complete cessation of growth following treatment
among responders (post-treatment average growth rate of 0.011 mm/yr among responders compared to 0.351 mm/yr prior to study entry; p<0.0001). Visual acuity preservation was achieved in 90% of these 10 patients. Importantly, 80% of these 10
patients were at high risk for vision loss with tumors close to the fovea or optic disc, highlighting the potential for vision preservation with this novel class of drugs. Of note, the current standard of care is radiotherapy, which leads to visual
acuity of <20/200 (the cutoff for legal blindness) in the treated eye in up to 87% of patients.1 The Phase 2 results are a significant achievement considering the typically poor prognosis
associated with choroidal melanoma, a rare and life-threatening ocular cancer, where there are no approved vision-preserving therapies to date.

therapy of uveal melanoma, and methods of counteracting this complication based on recent publications. Medicina (Kaunas). 2023;59(6):1131. |
Highly Favorable Safety Profile with No Dose-Limiting Toxicities
The safety profile of bel-sar was highly favorable in all participants regardless of dose. There were no treatment-related serious adverse events (SAEs)
reported. Ocular treatment-related AEs (TRAEs) were mild (Grade 1), included anterior chamber inflammation (18%) or cell (9%) and resolved without
sequelae. The vast majority (~70%) of the anterior chamber inflammation/cell events were self-limited, requiring no treatment, and resolved in a median of 6
days. For those events that did require treatment, topical steroid eye drops, administered for a median of 6 days, achieved complete resolution of the inflammation. Eye pain occurred in 9% of patients and was mild (Grade 1). Importantly, no
treatment-related posterior inflammation events (no vitritis, choroiditis, retinitis, retinal pigment epithelium changes, or vasculitis) were reported.
Many patients with early-stage choroidal melanoma currently face the difficult choice of whether to treat the cancer and risk losing their vision in the
treated eye, or delay treatment and risk the tumor progressing, said Dr. Ivana Kim, Director of the Ocular Melanoma Center, Mass Eye and Ear / Harvard Medical School. The Phase 2 end of study data that I presented at The Retina
Society Annual Meeting showed 80% tumor control rate, 90% vision preservation, and a highly favorable safety profile in early-stage CM. Bel-sar has the potential to become the first treatment that achieves the dual goals of treating the tumor while
also preserving vision, which could change the treatment paradigm for patients with this disease.
We believe these Phase 2 results provide
clinical evidence for bel-sar as a potential vision-sparing, first-line treatment option for patients with early-stage CM, said Dr. Jill Hopkins, Chief Medical Officer and President of Research and Development at Aura Biosciences.
Bel-sar is potentially a first-in-class novel therapy and we are excited to continue to advance this program, which is currently enrolling patients in our ongoing
global Phase 3 CoMpass trial.
Aura received written agreement from the U.S. Food and Drug Administration (FDA) under a Special Protocol
Assessment (SPA) for the design and planned analysis of the global Phase 3 CoMpass trial indicating concurrence by the FDA with the adequacy of the study, if successful, to address the objectives necessary to support Auras planned
biologics license application submission. Aura Biosciences is focused on enhancing treatment options and improving outcomes for patients with CM and other cancers.
Aura Virtual Ocular Oncology Investor Event
Aura will
host a virtual ocular oncology investor event featuring Dr. Ivana Kim, MD (Mass Eye and Ear) and Dr. Prithvi Mruthyunjaya, MD, MHS (Stanford University Byers Eye Institute) to discuss the Phase 2 end of study data on Thursday,
September 12, 2024, at 8:00 am Eastern Time. To register for the event, click here. A live question and answer session will follow the formal discussion.
The live webcast of Auras virtual ocular oncology investor event will be available on the Investors & Media page under the Events
& Presentations section of Auras website at https://ir.aurabiosciences.com/events-and-presentations, where a replay of the webcast will be
archived for 90 days following the presentation date.
