Marengo Therapeutics, Inc., a company pioneering novel therapeutics targeting the T cell receptor (TCR) Vβ to selectively activate the right T cell subsets to fight cancer, today announced that the first patient has been dosed in its ongoing clinical trial of STAR0602 (START-001). Marengo’s START-001 trial is a seamless Phase 1/2 clinical trial evaluating the safety and clinical activity of STAR0602 as monotherapy in a biomarker-enriched cohort of patients with PD-1 refractory advanced solid tumors.
The START-001 trial (NCT05592626) is currently enrolling patients at two top US cancer research institutes, National Institutes of Health (NIH)’s National Cancer Institute (NCI) and Mass General Hospital (MGH)/Harvard Medical School, co-led by seasoned clinical and translational researchers James Gulley, M.D., Ph.D., of NCI and Ryan Sullivan, M.D., of MGH. Additional top cancer centers are planned to join these clinical sites to support the further expansion of the study.
“The Center for Cancer Research’s Center for Immuno-Oncology at the NCI was recently established to explore fundamental questions of cancer immunotherapy through rigorous preclinical studies and translate these findings into clinical trials with the goal of developing novel therapies for a spectrum of cancers with high unmet medical needs. We look forward to studying this novel TCR agonist that selectively activates a subset of αβ T cells in cancer patients at the NCI,” said Dr. Gulley, Co-Director of the Center for Immuno-Oncology (CIO), Deputy Director of the Center for Cancer Research (CCR) at the NCI, and acting Clinical Director, NCI.
“The initiation of our first clinical trial with STAR0602 is an important milestone for Marengo and our selective T cell-targeted STAR platform,” said Zhen Su, M.D., MBA, Chief Executive Officer of Marengo. “The START-001 trial leverages a deep biology-driven study design to address high unmet clinical needs in patients for whom PD-1 therapies are no longer effective. Our clinical development approach utilizes a biomarker-enriched, tumor-agnostic strategy that offers a much-needed novel approach to cancer drug development. We are confident that evaluating STAR0602 in well-defined populations will allow us to efficiently investigate biological and clinical activity, paving the way for further investigation.”
“Cancer immunotherapy has transformed standard of care across many tumor settings and has significantly improved overall survival for patients with cancer. Despite these innovative therapies, most patients progress following treatment creating an urgent need to develop the next wave of novel therapeutics,” said Dr. Sullivan, Associate Director, Melanoma Program, MGH Cancer Center. “We are excited to test this novel biology via reinvigorating the T cell compartment in tumors to promote an antitumor immune response distinct from the PD-1 mechanism.”
