EMERYVILLE, Calif.--(BUSINESS WIRE)-- Eureka Therapeutics, Inc., a clinical-stage biotechnology company developing novel T-cell therapies to treat cancer, today announced the advancement of its ARYA-3 clinical trial to Phase II (NCT04864054). This milestone represents one of the first engineered T-cell programs targeting solid tumors to reach Phase II. The ARYA-3 trial is evaluating Eureka’s investigational ARTEMIS® ECT204 T-cell therapy in adult patients with GPC3-positive advanced hepatocellular carcinoma (HCC)GPC3-positive advanced hepatocellular carcinoma (HCC), the predominant type of liver cancer. Glypican 3 (GPC3) is a promising target for HCC therapies and is found in more than 70% of HCC cells. The GPC3 protein is also expressed in other solid tumors, including ovarian and lung cancer. The ARYA-3 trial has successfully completed Phase I and is now enrolling patients in Phase II. During this phase, the treatment’s efficacy and safety are evaluated in a larger patient population, offering crucial insights into its potential therapeutic benefits. “We are excited by the favorable safety pro promising early efficacy signals in Phase I of our ARYA-3 study. Moving to Phase II marks a significant milestone in our mission to advance cutting-edge therapies for cancer treatment,” said Dr. Cheng Liu, President and CEO of Eureka Therapeutics. “We remain committed to building a pipeline of next-generation T-cell therapy for solid tumors.” ARYA-3 is an Open-Label, Dose Escalation, Multi-Center Phase I/II Clinical Trial of ECT204 T-Cell Therapy. In this study, a patient’s T cells are collected and genetically modified to express Eureka’s proprietary anti-GPC3 ARTEMIS T cell receptors (AbTCR). These modified T cells are then reintroduced into the patient to specifically seek out and destroy GPC3-expressing cancerGPC3-expressing cancer cells. Eureka has previously demonstrated that its proprietary ARTEMIS T-cell receptor platform has several advantages over conventional chimeric antigen receptors (CARs), including better tumor infiltration, safety, and T cell persistence. The clinical trial is actively enrolling patients at both City of Hope and Kansas University Medical Center.
