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
“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
Results from the Retrospective Study
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.
- The vision results of patients with early-stage choroidal melanoma treated with radiotherapy showed the long term, progressive and irreversible loss of visual acuity in patients where tumors were close to the fovea.
- The loss of vision in radiotherapy patients was ≥3 lines in a majority of patients as early as 2 years and ≥6 lines as early as 3 years.
- We believe the comparison of the belzupacap sarotalocan and radiotherapy results supports the potential benefit of a targeted treatment achieving a statistically significant difference in visual acuity preservation as soon as two years including for both logMAR (Logarithm of the Minimum Angle of Resolution) vision (p = 0.0094) and change in logMAR vision (p = 0.0323).
- We believe the progressive loss of visual acuity with radiotherapy observed in this retrospective study underscores the urgent need for a vision preserving targeted therapy.
- The findings of this retrospective study were consistent with published clinical data supporting the irreversible loss of visual acuity after treatment with radiotherapy.
“We are committed to developing the first potential targeted therapy for patients with early-stage choroidal melanoma. We believe the visual acuity results of the retrospective matched case control study are exciting because they support the high unmet medical need for a long-term vision preserving therapy,” said Dr.
Study Limitations include the retrospective nature and utilizing a matched case control design. The mean follow-up for patients treated with belzupacap sarotalocan in this initial analysis was 15.6 months. Due to the retrospective nature of this analysis, it is hypothesis-generating; no formal conclusions can be drawn. Aura has also initiated a prospective matched case control study to further evaluate the long-term visual acuity results of belzupacap sarotalocan from the Phase 2 trial AU-011-202 using suprachoroidal administration versus radiotherapy.
