Aura Biosciences Reports Topline Data from a Retrospective Study of Belzupacap Sarotalocan (AU-011) versus Plaque Radiotherapy Supporting the Value of a Vision Preserving Therapy for the Treatment of Patients with Early-Stage Choroidal Melanoma

In this Retrospective Matched Case Control Study, Belzupacap Sarotalocan Achieved Statistically Significant Vision Preservation Compared to Plaque Radiotherapy, the Current Standard of Care

Excerpt from the Press Release:

CAMBRIDGE, Mass.–(BUSINESS WIRE)–Aura Biosciences Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing a novel class of virus-like drug conjugate (VDC) therapies for multiple oncology indications, reported results from a retrospective, matched case control study. This retrospective analysis assessed the visual acuity of patients following treatment with plaque radiotherapy compared with prospective data on visual acuity in subjects with early-stage choroidal melanoma treated with belzupacap sarotalocan by intravitreal administration in the Phase 1b/2 trial (NCT03052127).

“These results point to the high unmet medical need for a first line vision preserving therapy for the treatment of early-stage choroidal melanoma given the high levels of irreversible visual acuity loss with the current standard of care with radiotherapy,” said Carol Shields, MD, Chief of the Ocular Oncology Service at Wills Eye Hospital and Professor of Ophthalmology at Thomas Jefferson University. “Being able to treat the disease early, avoid radiotherapy and spare long-term vision loss in many patients, as well as potentially reducing the risk of metastatic disease, could represent a paradigm shift in our approach to the treatment of choroidal melanoma. This would be a significant improvement in the quality of life for patients with this life-threatening rare disease.”

Study Design

This retrospective, matched case control study compared visual acuity outcomes for 43 patients from Aura’s Phase 1b/2 trial evaluating intravitreal administration of belzupacap sarotalocan in patients with early-stage choroidal melanoma (AU-011-101, NCT03052127) to 150 patients from the subject database of a previously completed and published study where patients with small choroidal melanoma had been treated with plaque radiotherapy (Shields, et al. “Visual Outcome and Millimeter Incremental Risk of Metastasis in 1780 Patients With Small Choroidal Melanoma Managed by Plaque Radiotherapy.” JAMA Ophthalmology. September 27, 2018). Both cohorts of patients were at high risk for vision loss due to having the tumor edge within 3.0 mm of the fovea.
