Aura Biosciences Reports First Quarter 2024 Financial Results and Business Highlights

Continued Enrollment in Global Phase 3 CoMpass Trial in Small Choroidal Melanoma and Indeterminate Lesions

Ongoing Phase 1 Trial in Bladder Cancer Enrolling; Early Data Expected Mid-2024

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

BOSTON, May 09, 2024 (GLOBE NEWSWIRE) -- Aura Biosciences, Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing precision immunotherapies to treat solid tumors designed to preserve the function of the organ with cancer, today reported financial results for the first quarter ended March 31, 2024, and provided recent business highlights.

“Throughout the first quarter of 2024, the Company made significant progress across our ocular and urologic oncology therapeutic area programs,” said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura. “Enrollment continues in our global Phase 3 CoMpass trial in early-stage choroidal melanoma, and we expect early Phase 1 data from our bladder cancer trial mid-2024. Aura is committed to changing the treatment paradigms in ocular and urologic oncology, both areas where patients desperately need novel therapies that can effectively treat the tumor and also preserve the function of the organ with cancer.”

Recent Pipeline Developments

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

• The CoMpass trial continues to progress in the United States with additional site activations and a 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).
  

Bel-sar is being explored for additional ocular oncology indications.

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

Choroidal Metastasis
The Company’s plan is to initiate clinical development in choroidal metastasis, an indication with a high unmet medical need and no drugs approved. Choroidal metastasis is the second potential ocular oncology indication for bel-sar, affecting approximately 20,000 patients in the United States and Europe annually. 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. Positive preclinical data evaluating bel-sar in this indication were presented at the Association for Research in Vision and Ophthalmology (ARVO) 2024 Annual Meeting.

These preclinical data demonstrate that binding of bel-sar was consistent across all conjunctival melanoma cell lines tested which included both primary and recurrent cell lines. The mechanism of action was also consistent with prior preclinical data presented by the Company demonstrating that bel-sar induced immunogenic cell death, which was characterized by enhanced exposure of damaged associated molecular patterns (DAMPs) and engulfment by THP1-derived macrophages. We believe these recent preclinical data further support clinical development of bel-sar in cancers of the ocular surface.

A Phase 1 trial of bel-sar for the treatment of non-muscle invasive bladder cancer (NMIBC) and muscle invasive bladder cancer (MIBC) is currently ongoing, with early data expected in mid-2024.

NMIBC and MIBC represent 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 tissue and tumor specific immune response to prevent disease progression and recurrence while allowing the patients to be treated in the office by urologists and potentially avoiding the need for surgery. The Company received Fast Track designation from the Oncology Division of the FDA for NMIBC in June 2022.

• 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.
  
  
• Preliminary data from the first patient in the light activated cohort of the trial demonstrated a clinical complete response demonstrated by absence of cancer cells on histopathology with evidence of extensive necrosis and immune activation after a single administration of bel-sar followed by light activation.
  
  
• Phase 1 trial continues to enroll, with early data expected mid-2024.
  

Recent Corporate Events

Strengthened leadership team with appointment of Conor Kilroy as General Counsel and Secretary.

• Mr. Kilroy previously served as general counsel and secretary at Neurogastrx, Inc. and Ironwood Pharmaceuticals, Inc., among other roles. He brings years of legal experience in the biopharmaceutical industry across clinical and commercial stage organizations.
  

First Quarter 2024 Financial Results

• As of March 31, 2024, Aura had cash and cash equivalents and marketable securities totaling $202.9 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 $17.1 million for the three months ended March 31, 2024 from $14.4 million for the three months ended March 31, 2023, primarily due to ongoing clinical costs related to the progression of our Phase 2 study of bel-sar in early-stage choroidal melanoma and contract research organization costs associated with the advancement of our Phase 3 trial of bel-sar in early-stage choroidal melanoma and higher personnel expenses related to growth of our Company.
  
  
• General and administrative expenses increased to $5.3 million for the three months ended March 31, 2024 from $5.0 million for the three months ended March 31, 2023. General and administrative expenses include $1.4 million and $1.1 million of stock-based compensation for the three months ended March 31, 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 March 31, 2024 was $19.7 million compared to $17.5 million for the three months ended March 31, 2023.
