Overview

A2 Biotherapeutics is a clinical-stage biotechnology company founded in 2018 and based in Agoura Hills, California. The company specializes in developing innovative, precision-targeted cell therapies for the treatment of solid tumors. Key aspects of A2 Biotherapeutics include:

Technology Platform

At the core of A2 Bio's approach is the proprietary Tmod™ platform, a modular and flexible system that enables the creation of diverse cancer therapy candidates. This platform utilizes a combination of activator and blocker receptors to precisely target tumor cells while sparing normal cells. The blocker technology acts as a self-actuated safety switch, leveraging irreversible genetic losses specific to tumor cells to protect normal tissues.

Pipeline

A2 Bio has a robust pipeline featuring one clinical and three pre-clinical programs targeting various solid tumors. The two lead programs are:

  1. A2B530: A CAR-T cell therapy targeting tumors that express carcinoembryonic antigen (CEA) but lack the HLA-A*02 antigen. It is being studied in the EVEREST-1 clinical trial for patients with non-small cell lung cancer (NSCLC), colorectal cancer (CRC), and pancreatic cancer (PANC).
  2. A2B694: A CAR-T cell therapy targeting tumors that express mesothelin (MSLN) but lack the HLA-A*02 antigen. It is intended for a clinical trial studying patients with NSCLC, CRC, PANC, ovarian cancer (OVCA), and mesothelioma. In addition to these autologous programs, A2 Bio is also developing allogeneic candidates.

Clinical Trials

The company is conducting seamless phase 1/2 clinical studies, including EVEREST-1 and EVEREST-2. Patient enrollment is facilitated through the BASECAMP-1 prescreening study, which utilizes AI-enabled precision diagnostics.
