"We believe that bel-sar has the potential to transform the treatment paradigm in multiple rare oncology indications starting with ocular cancers and more broadly across many solid tumors such as bladder cancer. The data presented from the Phase 2 trial in early-stage choroidal melanoma and the Phase 1 trial in NMIBC demonstrated bel-sar’s potential as a front-line treatment option across multiple tumor types," said Elisabet de los Pinos, Chief Executive Officer of Aura Biosciences. "These data highlight the potential clinical benefit of a novel dual mechanism of action driven by highly targeted cytotoxicity and robust cell-mediated immunity. We look forward to continuing to advance our pipeline across multiple indications with high unmet patient need."

Recent Pipeline Developments

Early-Stage Choroidal Melanoma

Early-stage choroidal melanoma represents an area of high unmet need with no drugs approved. The Company previously received Orphan Drug Designation from the United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) and Fast Track designation from the FDA for the treatment of early-stage choroidal melanoma. The CoMpass trial is under a Special Protocol Assessment (SPA) agreement with the FDA.

Update on Ongoing Phase 3 CoMpass Trial: CoMpass is the first registration-enabling study in early-stage choroidal melanoma. The study is a global, Phase 3, randomized trial evaluating bel-sar treatment against a sham control arm and includes an enrichment strategy to enroll approximately 100 patients with documented tumor growth.

The CoMpass trial is actively enrolling globally. To identify appropriate patients to meet the enrichment strategy of documented growth, the Company has enabled a pre-screening ‘run in’ period. Globally, since June 2024, investigators have registered over 175 patients in pre-screening as having met initial enrollment criteria for the study. The acceleration in pre-screening is driven by increasing momentum in the United States and European Union.

Additional Ocular Oncology Indications:

In addition to early-stage choroidal 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 has initiated a Phase 2 clinical trial in metastases to the choroid and has sites activated with patients in prescreening. Metastases to the choroid is an indication with high unmet medical need and no approved therapies. The Company expects initial data from this trial in 2025.

Metastases to the choroid represents the second potential ocular oncology indication for bel-sar, affecting approximately 20,000 patients annually in the United States and Europe. The Company previously received FDA Fast Track designation for bel-sar in this indication.

Cancers of the Ocular Surface

The Company’s third potential ocular oncology indication is cancers of the ocular surface, which affects 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.

Bladder Cancer

Positive additional data from the Company’s Phase 1 trial of bel-sar in patients with NMIBC was presented at the 40th Annual European Association of Urology Congress. In totality, the data demonstrate clinical complete responses as well as robust cell mediated immunity across the intermediate- and high-risk disease spectrum.

These data now include the histopathological assessment of all 10 patients after treatment with light activation and the full evaluation of safety and tumor response in two additional patients with high-risk NMIBC. One patient with high-risk disease (due to BCG failure) demonstrated a clinical complete response. Further, to evaluate the local immune response after the treatment with bel-sar in the TME, multiplex immunofluorescence staining for key immune cell types was performed on tumor biopsies from three patients. These early observations show induction of effector immunity and the development of local active immunosurveillance, highlighting key features of bel-sar’s dual mechanism of action and the potential to translate into durable treatment responses. The Company previously announced early data from this Phase 1 trial in October 2024. Details of the updated results of the Phase 1 NMIBC trial can be found here.

Corporate Updates


The Company will host a virtual urologic oncology investor event today, at 4:30 pm ET, featuring Neal Shore, MD, FACS (Carolina Urologic Research Center), Gary Steinberg, MD, FACS (Rush University) and Jennifer A. Linehan, MD (Saint John’s Cancer Institute), to discuss the data from the Phase 1 trial in NMIBC, as well as a bladder cancer program update including the Phase 1b/2 trial and future development plans.

Full Year and Fourth Quarter 2024 Financial Results


As of December 31, 2024, Aura had cash and cash equivalents and marketable securities totaling $151.1 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 $22.3 million and $73.3 million for the three months and full year ended December 31, 2024, respectively, from $20.3 million and $65.2 million for the three months and full year ended December 31, 2023, respectively, primarily due to ongoing clinical and contract research organization costs associated with the progression of the Company’s Phase 3 global trial and manufacturing and development costs for bel-sar.


General and administrative expenses increased to $5.5 million and $22.8 million for the three months and full year ended December 31, 2024, respectively, from $4.5 million and $19.8 million for the three months and full year ended December 31, 2023, respectively. General and administrative expenses include $1.4 million and $1.2 million of stock-based compensation for the three months ended December 31, 2024 and 2023, respectively. The increase was primarily driven by personnel expenses, as well as increases in general corporate expenses related to the global growth of the Company.


Net loss for the three months and full year ended December 31, 2024, was $25.8 million and $86.9 million, respectively, compared to $22.1 million and $76.4 million for the three months and full year ended December 31, 2023, respectively.
