Item 7.01 | Regulation FD Disclosure. |
On October 3, 2022, Aura Biosciences, Inc. (the “Company”) issued a press release titled “Aura Biosciences Announces Interim Phase 2 Data Evaluating Suprachoroidal Administration of Belzupacap Sarotalocan (AU-011) for the First-Line Treatment of Patients with Early-Stage Choroidal Melanoma Presented at AAO 2022” and updated its corporate presentation for use in meetings with investors, analysts and others. A copy of the press release and a copy of the corporate presentation are furnished herewith as Exhibits 99.1 and 99.2, respectively, and are incorporated herein by reference.
Also on October 2, 2022, the Company presented Phase 2 interim safety and efficacy data evaluating the safety and efficacy of suprachoroidal (“SC”) administration using belzupacap sarotalocan (Bel-Sar; AU-011) for the first-line treatment of patients with early-stage choroidal melanoma at the American Academy of Ophthalmology (“AAO”) 2022 Annual Meeting. A copy of its “A Phase 2 Trial of Belzupacap Sarotalocan (AU-011), a First-in-Class Targeted Therapy for Choroidal Melanoma via Suprachoroidal Administration” slide presentation is furnished herewith as Exhibit 99.3 and incorporated herein by reference.
The information furnished under this Item 7.01, including Exhibits 99.1, 99.2 and 99.3 , shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.
On October 2, 2022, the Company announced that interim Phase 2 data evaluating the safety and efficacy of SC administration using its first VDC product candidate, belzupacap sarotalocan, for the first-line treatment of patients with early-stage choroidal melanoma (indeterminate lesions and small choroidal melanoma (“IL/CM”)) were presented at the AAO 2022 Annual Meeting held September 30-October 3, 2022, in Chicago, IL.
This Phase 2 trial (NCT04417530) is assessing the safety and preliminary efficacy of single- and multiple ascending-doses of belzupacap sarotalocan up to three cycles of treatment via SC administration for the first-line treatment of early-stage choroidal melanoma (IL/CM). 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) received 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. These endpoints have been discussed with the U.S. Food and Drug Administration and are planned to be used in the pivotal program. The results, with an average of six months follow up in patients that received three cycles of therapy in Cohorts 5 and 6, showed a statistically significant reduction in the tumor growth rate (-0.296 mm/yr, p = 0.0007) compared to each patient’s documented growth rate at study entry, and an 88.9% (8/9) tumor control rate. In addition, the visual acuity preservation rate was 88.9% (8/9) 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 safety profile of belzupacap sarotalocan was generally favorable, with no dose-limiting toxicities or treatment-related SAEs reported as of August 19, 2022. There was no posterior inflammation and only mild anterior inflammation (Grade 1) in 20% of the patients. Treatment-related AEs were predominantly mild and resolved without sequalae. The Company believes these interim results indicate that belzupacap sarotalocan may offer a targeted vision preserving therapy for the first-line treatment of primary CM, where 80% of patients are diagnosed early and have no approved therapies to date.
