Aulos Bioscience to Present Updated Phase 1/2 Clinical Trial Results for Novel IL-2 Therapeutic AU-007 in Advanced Solid Tumor Cancers at 2024 ASCO Annual Meeting


LARKSPUR, Calif.--(BUSINESS WIRE)--Aulos Bioscience, an immuno-oncology company working to revolutionize cancer care through the development of potentially best-in-class IL-2 therapeutics, today announced that updated Phase 1/2 data for AU-007 will be presented at the American Society of Clinical Oncology (ASCO) 2024 Annual Meeting. AU-007 is a human IgG1 monoclonal antibody designed using artificial intelligence to harness the power of interleukin-2 (IL-2) to eradicate solid tumors in patients with unresectable locally advanced or metastatic cancers. It is the first AI-designed human monoclonal antibody to be tested in a clinical trial. The ASCO meeting is being held online and at McCormick Place in Chicago, Illinois, from May 31–June 4, 2024.

Details of the poster presentation are as follows:

Poster Title: Updated results of a phase 1/2 study of AU-007, a monoclonal antibody (mAb) that binds to IL-2 and inhibits CD25 binding, in patients with advanced solid tumors.
Abstract: 2527
Session Type/Title: Poster Session/Developmental Therapeutics—Immunotherapy
Session Date and Time: Saturday, June 1, 2024, 9:00 a.m.-12:00 p.m. CDT

The poster will be presented in the Exhibit Hall at McCormick Place. An electronic version will also be available on the ASCO 2024 online meeting platform.

About AU-007
AU-007 is a computationally designed, human IgG1 monoclonal antibody 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 leverages 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.
