"We have begun 2022 with strong momentum, being on track to advance AU-011 in the clinic in multiple indications with significant unmet medical need. We look forward to initiating the pivotal trial in patients with early stage choroidal melanoma, which is the first indication in our ocular oncology franchise, in the second half of this year," said Elisabet de los Pinos, Ph.D., Chief Executive Officer of Aura. "We are excited to have received Orphan Drug Designation from the European Commission, further validating the important role that AU-011 could play in the treatment of patients with this life-threatening disease globally."
Dr. de los Pinos continued: "We are also excited to expand our pipeline into additional solid tumors by initiating our Phase 1 trial in non-muscle invasive bladder cancer (NMIBC) in the second half of this year. We are encouraged by the NMIBC preclinical data that we presented at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary Cancer Symposium, which supports this indication, as well as the preclinical data that will be presented at the 2022 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting that further supports the broad oncology potential of our VDC platform. Underscoring our pipeline advancement is a solid balance sheet, with our cash position supporting operations into 2024."
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. Aura plans to select the route of administration and treatment regimen to initiate the pivotal program in CM in the second half of 2022.
Orphan Drug Designation granted to AU-011 by the European Commission for the treatment of uveal melanoma (includes CM). The European Commission grants Orphan Drug Designation for medicinal products intended to treat life-threatening or chronically debilitating conditions that affect fewer than five in 10,000 people in the European Union (EU) and when no satisfactory method of diagnosis, prevention, or treatment of the condition can be authorized. The designation provides certain benefits and incentives in the EU, including protocol assistance, fee reductions, and ten years of market exclusivity once the medicine is on the market.
Leveraging the broad tumor targeting capabilities of the VDC platform, Aura is planning to pursue clinical development of AU-011 in NMIBC.
Preclinical data demonstrating applicability of AU-011 in bladder cancer was presented at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary Cancer Symposium. Preclinical results demonstrated that AU-011’s targeting of bladder cancer cells through heparan sulfate proteoglycans is tumor grade agnostic. Tumor binding and distribution of AU-011 was evident in both ex vivo human bladder cancer tissues and in an in vivo murine bladder cancer model. Collectively, these results support further investigation of the use of AU-011 in patients with NMIBC.
NMIBC is an area of high unmet need with no approved targeted therapies. The AU-011 mechanism of action supports the opportunity for use as a first-line treatment following initial diagnosis and/or for the treatment of Bacillus Calmette-Guerin (BCG) refractory disease. The planned Phase 1 trial will evaluate the safety and early proof of mechanism, exploring local necrosis and evidence of immune activation, and Aura expects to initiate the trial in the second half of 2022.
Aura is investigating additional potential indications for AU-011.
Preclinical data highlighting the ability to target a broad number of tumor types will be presented as part of the 2022 American Association for Cancer Research (AACR) (Free AACR Whitepaper) Annual Meeting. The data that will be presented at the AACR (Free AACR Whitepaper) annual meeting support AU-011’s potential use to target modified 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 to be considered for AU-011 in the clinic, particularly those derived from neural or epithelial lineages. The AACR (Free AACR Whitepaper) annual meeting is being held April 8-13, 2022 in New Orleans, LA.

Recent Events
Aura hosted a virtual Investor Day to discuss AU-011 in ocular oncology on Tuesday, March 22, 2022. The program included an overview of CM, AU-011’s unique mechanism of action, and a summary of the clinical data of AU-011 in CM to date. This was followed by a moderated Q&A with ocular oncology leaders Dr. Carol Shields, Chief of the Ocular Oncology Service at Wills Eye Hospital and Professor of Ophthalmology at Thomas Jefferson University, and Dr. Hans Grossniklaus, Senior Professor of Ophthalmology and Founding Director of the Ocular Oncology and Pathology Service at Emory University. The webcast is available here.
Full Year and Fourth Quarter 2021 Financial Results
As of December 31, 2021, Aura had cash and cash equivalents totaling $149.1 million. Aura believes its current cash and cash equivalents are sufficient to fund its operations into 2024.
Research and development expenses increased to $8.0 million and $25.2 million for the three months and full year ended December 31, 2021, respectively, from $3.5 million and $18.0 million for the three months and full year ended December 31, 2020, respectively, primarily due to ongoing manufacturing development costs for AU-011 and higher personnel expenses from growing headcount due to the progression of clinical trials.
General and administrative expenses increased to $3.6 million and $10.1 million for the three months and full year ended December 31, 2021, respectively, from $1.4 million and $4.2 million for the three months and full year ended December 31, 2020, respectively. General and administrative expenses include $0.9 million and $0.1 million of stock-based compensation for the three months ended December 31, 2021 and 2020, respectively. The increase was primarily related to personnel expenses due to an increase in headcount, as well as general increases in audit, legal, consulting, insurance, regulatory, and facilities expenses related to operating as a public company.
Net loss for the three months and full year ended December 31, 2021, was $11.6 million and $35.3 million, respectively, compared to $4.9 million and $22.2 million for the three months and full year ended December 31, 2020, respectively.
