Company to Present Early Non-muscle Invasive Bladder Cancer (NMIBC) Data from Ongoing Phase 1 Trial at a Urologic Oncology Investor Event in October 2024

Phase 2 End of Study Data Evaluating Suprachoroidal Administration of Bel-sar for the First-Line Treatment of Patients with Early-stage Choroidal Melanoma to be Presented at Retina Society Annual Meeting

Strong Cash Position Expected to Fund Operations into Second Half of 2026

BOSTON, Aug. 08, 2024 (GLOBE NEWSWIRE) — Aura Biosciences, Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing precision therapies to treat a range of solid tumors designed to preserve organ function, today reported financial results for the second quarter ended June 30, 2024, and provided recent business highlights.

“We are excited by the progress we made in the second quarter across all our clinical programs and in particular in our bladder cancer clinical trial. We look forward to our upcoming urologic oncology virtual event in October, where we plan to share early data in NMIBC,” said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura. “We are well-capitalized and remain focused on the execution of our ongoing clinical trials in ocular and urologic oncology, two areas where novel treatment options are needed that can provide effective local treatment while preserving organ function.”

Recent Pipeline Developments 

Bladder Cancer

A Phase 1 trial of bel-sar for the treatment of bladder cancer is currently ongoing.  The company plans to host a virtual urologic oncology investor event featuring key opinion leaders (KOLs) in October 2024. Early NMIBC data from the ongoing Phase 1 trial is expected to be presented at this event.

• Bladder cancer represents an area of high unmet need with approximately 80,000 patients diagnosed in the United States annually. We believe bel-sar has the potential to selectively treat and induce a tumor specific immune response to prevent disease progression and recurrence, while allowing patients to be treated in-office by urologists and potentially avoiding the need for surgery. The Company received Fast Track designation from the FDA’s Division of Oncology for the treatment of NMIBC.

The ongoing Phase 1 multi-center, open-label clinical trial is expected to enroll approximately 21 adult patients. The trial is designed to assess the safety and feasibility of bel-sar as a monotherapy. The trial includes histopathological evaluation after local treatment to assess bel-sar’s biological activity, including the evaluation of focal necrosis and immune activation after a single dose of treatment.

Primary Uveal Melanoma

Phase 2 end of study data in small choroidal melanoma and indeterminate lesions will be presented at the Retina Society Annual Meeting taking place September 11-15, 2024, in Lisbon, Portugal.

Enrollment continues in global Phase 3 CoMpass trial for the treatment of small choroidal melanoma and indeterminate lesions.

• CoMpass trial continues to progress globally with site activations, patient enrollment and strong endorsement from the ocular oncology community. This trial has a global enrollment target of approximately 100 patients.
   
• CoMpass is a global, Phase 3, randomized, superiority trial evaluating bel-sar treatment against a sham control arm. Adult participants will be randomized 2:1:2 to undergo three cycles of treatment with either a high or low dose of bel-sar or to receive a sham control. The primary endpoint is time to tumor progression at 15 months of follow-up, as agreed upon with the United States Food and Drug Administration (FDA) under a Special Protocol Assessment (SPA).
   
• Early-stage choroidal melanoma represents an area of high unmet need with approximately 8,000 patients diagnosed in the United States and Europe annually. The Company received Orphan Drug Designation from the FDA and the European Medicines Agency (EMA) and Fast Track designation from the FDA for the treatment of primary uveal melanoma.

Additional Ocular Oncology Indications:

In addition to primary uveal melanoma, bel-sar is being explored for metastases to the choroid and cancers of the ocular surface. These three ocular oncology indications have a collective incidence of greater than 60,000 patients annually in the United States and Europe.

Metastases to the Choroid

The Company plans to initiate clinical development in metastases to the choroid, an indication with a high unmet medical need and no approved therapies. Metastases to the choroid is the second potential ocular oncology indication for bel-sar, affecting approximately 20,000 patients in the United States and Europe annually. The Company received Fast Track designation from the FDA’s Division of Oncology for the treatment of metastases to the choroid. The Company is on track to initiate a Phase 2 trial in 2024.

Cancers of the Ocular Surface

Cancers of the ocular surface is the Company’s third potential ocular oncology indication affecting approximately 35,000 patients in the United States and Europe annually. The Company continues to advance its preclinical work designed to be IND-enabling in cancers of the ocular surface.

Recent Corporate Events

• The Company hosted a virtual KOL event with global opinion leaders in Ocular Oncology, “Pioneering a New Standard of Care in Ocular Oncology,” on May 29, 2024. A replay of the webcast is available on the “Investors & Media” page under the “Events & Presentations” section of Aura’s website at https://ir.aurabiosciences.com/events-and-presentations.

Second Quarter 2024 Financial Results   

• As of June 30, 2024, Aura had cash and cash equivalents and marketable securities totaling $187.4 million. The Company believes its current cash and cash equivalents and marketable securities are sufficient to fund its operations into the second half of 2026.
   
• Research and development expenses increased to $16.9 million for the three months ended June 30, 2024 from $15.1 million for the three months ended June 30, 2023, primarily due to higher personnel expenses related to growth of our Company.
   
• General and administrative expenses increased to $5.9 million for the three months ended June 30, 2024 from $5.2 million for the three months ended June 30, 2023. General and administrative expenses include $1.6 million and $1.2 million of stock-based compensation for the three months ended June 30, 2024 and 2023, respectively. The increase was primarily driven by personnel expenses, as well as increases in general corporate expenses related to the growth of our Company.
   
• Net loss for the three months ended June 30, 2024 was $20.3 million compared to $18.3 million for the three months ended June 30, 2023.
