LARKSPUR, Calif.: Aulos™ Bioscience, an immuno-oncology company working to revolutionize cancer care through development of immune-activating antibody therapeutics, today announced dosing of its first patient with a combination of AU-007, the anti-PD-1 antibody nivolumab and low-dose, subcutaneous aldesleukin in a Phase 2 expansion cohort focused on second-line treatment of melanoma. This new cohort is part of Aulos’ Phase 1/2 clinical trial of AU-007 in patients with unresectable locally advanced or metastatic cancer.

Preliminary Phase 2 data presented in November at the Society for Immunotherapy of Cancer (SITC) 39th Annual Meeting showed that a combination of AU-007 and low-dose, subcutaneous aldesleukin is clinically active in patients with melanoma, with durable objective responses achieved. The additional Phase 2 cohort in melanoma now allows the nivolumab combination portion of this study to progress.

“We are excited that the first patient is receiving treatment in this new Phase 2 cohort evaluating AU-007 in combination with nivolumab,” said Aron Knickerbocker, Aulos Bioscience’s president and chief executive officer. “Given its unique mechanism of action and the positive data presented to date on AU-007 and low-dose, subcutaneous aldesleukin, we believe that AU-007 holds real promise as a novel immuno-oncology treatment in combination with checkpoint inhibitors in multiple cancer types. These include non-small cell lung cancer, for which we initiated a Phase 2 cohort with the anti-PD-L1 antibody avelumab in November, and now melanoma.”

AU-007 is the first human monoclonal antibody designed with the assistance of artificial intelligence to enter a human clinical trial. The antibody harnesses the power of interleukin-2 (IL-2) by binding precisely to the portion of IL-2 that binds to CD25, which prevents IL-2 from binding to high-affinity IL-2 receptors on Tregs, vasculature, pulmonary tissue and eosinophils. This redirects IL-2 to medium-affinity receptors on effector T cells (Teffs) and natural killer (NK) cells, which expand and kill tumor cells.

Aulos anticipates presenting preliminary data from the Phase 2 cohort evaluating AU-007, nivolumab and low-dose, subcutaneous aldesleukin as a second-line treatment for melanoma in the second half of 2025. The company will present new Phase 2 data for AU-007 and low-dose, subcutaneous aldesleukin without a checkpoint inhibitor as a second-line treatment for melanoma at the American Association for Cancer Research (AACR) Annual Meeting later this month.

About AU-007

AU-007 is a human IgG1 monoclonal antibody designed by leveraging artificial intelligence that is highly selective to the CD25-binding portion of IL-2. With a mechanism of action unlike any other IL-2 therapeutic in development, AU-007 redirects IL-2 to reinforce anti-tumor immune effects. This is achieved by preventing IL-2, either exogenous or secreted by effector T cells, from binding to trimeric receptors on regulatory T cells while still allowing IL-2 to bind and expand effector T cells and NK cells. This prevents the negative feedback loop caused by other IL-2-based treatments and biases the immune system toward activation over suppression. AU-007 also prevents IL-2 from binding to CD25-containing receptors on eosinophils, as well as vasculature and pulmonary endothelium, which may significantly reduce the vascular leak syndrome and pulmonary edema associated with high-dose IL-2 therapy.

About Aulos

Aulos Bioscience is an immuno-oncology company working to revolutionize cancer patient care through immune-activating antibody therapeutics that direct patients’ immune systems toward killing tumor cells. Matching world-class machine learning from co-founder Biolojic Design with an in-depth understanding of the immune system, Aulos’ initial clinical candidate, AU-007, is a human antibody designed by leveraging artificial intelligence that harnesses the power of IL-2 to induce tumor killing while limiting the immunosuppression and toxicities typically associated with this validated pathway. The company was founded by Biolojic Design and Apple Tree Partners (ATP) and is led by pioneers in the fields of artificial intelligence, antibody development and cancer immunotherapies.
