On Track to Meet Multiple Clinical Milestones for AU-011 in 2H 2022: Initiate Pivotal Trial in Choroidal Melanoma, Initiate Phase 1 Trial in Non-Muscle Invasive Bladder Cancer, and Submit IND for Choroidal Metastases

CAMBRIDGE, Mass.--(BUSINESS WIRE)--May 12, 2022-- Aura Biosciences Inc. (NASDAQ: AURA), a clinical-stage biotechnology company developing a novel class of virus-like drug conjugate (VDC) therapies for multiple oncology indications, today reported financial results for the first quarter ended March 31, 2022, and provided clinical development and operational highlights.

“We continue to advance the AU-011 overall development program and look forward to several upcoming clinical milestones, in the second half of this year,” said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura. “We remain on track with our Phase 2 suprachoroidal study in early stage choroidal melanoma and plan to finalize a decision on the route of administration and initiate our pivotal program before the end of the year. Beyond primary choroidal melanoma, we continue to build our ocular oncology franchise and we are on track to file an Investigational New Drug application for choroidal metastases, with pre-clinical data presented at ARVO last week. Lastly, we will be initiating our Phase 1 trial in non-muscle invasive bladder cancer, with multiple clinical sites in the US. While we remain focused on preparing for our pivotal trial in choroidal melanoma, we are also excited by the prospect of leveraging our VDC therapies across multiple oncology indications and providing new treatment options for patients with life threatening cancers.”

Recent Pipeline Developments

• AU-011 is being developed for the treatment of early-stage choroidal melanoma (CM), a life-threatening rare disease with no approved drugs. Orphan Drug Designation was recently granted to AU-011 by the European Commission for the treatment of uveal melanoma (includes CM). AU-011 was previously granted Orphan Drug and Fast Track Designations for this indication by the U.S. Food and Drug Administration (FDA). Aura plans to select the route of administration and treatment regimen to initiate the pivotal program in CM in the second half of 2022.
  
  
• Beyond primary CM, we continue to build our ocular oncology franchise with choroidal metastases being the second potential ocular indication.
  
  
  • Abstract highlighting AU-011’s efficacy as a single agent and as a combination therapy with checkpoint inhibitors has been selected for publication at the upcoming 2022 American Society of Clinical Oncology (ASCO) Annual Meeting. The abstract, titled “A novel virus-like drug conjugate (VDC) in combination with immune checkpoint inhibitors for the treatment of primary tumors and distant metastasis” will be published as part of the Session titled “Developmental Therapeutics - Immunotherapy” and will be available on the ASCO website on Thursday, May 26, 2022, at 5:00 pm. ET.
    
    
  • Preclinical data highlighting AU-011 anti-tumor activity was presented at the 2022 Association of Research in Vision and Ophthalmology (ARVO) Annual Meeting. Preclinical results highlighted AU-011’s targeted cytotoxicity in tumor cells derived from the most common cancer types known to metastasize to the choroid in the eye. AU-011 showed dose dependent activity in vivo using cognate tumor models. These results support further evaluation of AU-011 as a potential treatment for choroidal metastases, the most common type of intraocular malignancy in adults. Aura plans to file an Investigational New Drug (IND) application with the FDA in the second half of 2022 for choroidal metastases.
    
    
• Leveraging the broad tumor targeting capabilities of the VDC platform, Aura is planning to pursue clinical development of AU-011 in non-muscle invasive bladder cancer (NMIBC).
  
  
  • The AU-011 mechanism of action supports the opportunity for use as a first-line treatment of NMIBC, an area of high unmet need with no approved targeted therapies. The planned Phase 1 trial will evaluate the safety and early proof of mechanism, exploring distribution, local necrosis and evidence of immune activation. Aura expects to initiate the trial in the second half of 2022 with initial Phase 1 data in 2023.
    
    
• Aura is investigating additional potential indications for AU-011.
  
  
  • Preclinical data highlighting the ability to target a broad number of tumor types was presented as part of the 2022 American Association for Cancer Research (AACR) Annual Meeting. The data that was presented at the AACR annual meeting support AU-011’s potential to target associated heparan-sulfate proteoglycans that are overexpressed on the tumor cell surface. Activity was observed in every tumor type tested, indicating that there are numerous solid tumors that AU-011 can target and potentially treat, particularly those derived from neural or epithelial lineages. The AACR annual meeting was held April 8-13, 2022 in New Orleans, LA.

First Quarter 2022 Financial Results

• As of March 31, 2022, Aura had cash and cash equivalents and marketable securities totaling $133.3 million. Aura believes its current cash and cash equivalents and marketable securities are sufficient to fund its operations into 2024.

• Research and development expenses increased to $8.3 million for the three months ended March 31, 2022 from $4.2 million for the three months ended March 31, 2021, primarily due to ongoing manufacturing and development costs for AU-011 and higher personnel expenses from growing headcount.

• General and administrative expenses increased to $4.5 million for the three months ended March 31, 2022 from $1.7 million for the three months ended March 31, 2021. General and administrative expenses include $1.0 million and $0.1 million of stock-based compensation for the three months ended March 31, 2022 and 2021, respectively. The increase was primarily driven by personnel expenses, as well as increases in general corporate expenses related to operating as a public company.

• Net loss for the three months ended March 31, 2022 was $12.8 million compared to $5.9 million for the three months ended March 31, 2021.

About Aura Biosciences

Aura Biosciences, Inc. is a clinical-stage biotechnology company developing virus-like drug conjugates (VDCs), a novel class of therapies, for the treatment of multiple oncology indications. Aura’s lead VDC candidate, AU-011 (belzupacap sarotalocan), consists of a virus-like particle conjugated with an anti-cancer agent. AU-011 selectively targets and destroys cancer cells and activates the immune system with the potential to create long-lasting anti-tumor immunity. AU-011 is currently in development for ocular cancers, with an ongoing Phase 2 dose escalation clinical trial evaluating first-line treatment of choroidal melanoma, a vision- and life-threatening form of eye cancer where standard of care with radiotherapy leaves patients with severe comorbidities, including major vision loss. Aura plans to develop AU-011 across its ocular oncology franchise including for the treatment of patients with choroidal metastases. In addition, leveraging Aura’s technology platform, Aura is developing AU-011 more broadly across multiple cancers, starting with a planned Phase 1 clinical trial in patients with non-muscle invasive bladder cancer. Aura is headquartered in Cambridge, MA.
