CAR T cell therapy candidate will be evaluated in Phase I multicenter, open-label clinical trial.
Adicet Bio has announced that the FDA has cleared its Investigational New Drug (IND) application to evaluate ADI-270, an armored allogeneic “off-the-shelf” gamma delta chimeric antigen receptor (CAR) T cell therapy candidate targeting CD70+ cancers, for the treatment of relapsed/refractory renal cell carcinoma (RCC). Adicet plans to initiate a Phase I clinical trial to assess the safety and anti-tumor activity of ADI-270 in RCC patients later this year.1
The future study evaluating ADI-270 will be a Phase I multicenter, open-label clinical trial that is designed to investigate ADI-270 as monotherapy in adults with relapsed or refractory clear cell RCC. Following lymphodepletion, patients will be eligible to receive a single dose of ADI-270 with a starting dose level of 3E8 CAR+ cells. The trial is set to have dose escalation and dose expansion phases.
According to the American Cancer Society, kidney cancer is one of the 10 most common cancers in both men and women in the United States. In 2024, approximately 81,610 new cases of kidney cancer (52,380 in men and 29,230 in women) will be diagnosed.2
“ADI-270 is the first ever gamma delta 1 CAR T cell therapy candidate to enter clinical trials for the treatment of solid tumors,” Chen Schor, president and CEO of Adicet Bio said in a press release. “The FDA’s clearance of our IND application to evaluate ADI-270 in patients with RCC underscores a significant achievement for Adicet. ADI-270 is a third-generation CAR T designed to target CD70+ tumors with high specificity, increased exposure, persistence and tumor infiltration, while addressing immunosuppressive factors in the tumor microenvironment. RCC is the most common type of kidney cancer and has a high unmet need with limited viable treatment options available. With its highly differentiated profile, we believe that ADI-270 has the potential to become an important therapeutic option for patients with RCC and other CD70+ tumors.”
Earlier in April, Adicet shared preclinical data that showed anti-tumor activity of ADI-270 in multiple CD70-positive solid and hematological cancer models.3

Behind the Buzz: Why Clinical Research Leaders Flock to SCOPE Summit
February 7th 2025In this episode, we meet with Micah Lieberman, Executive Conference Director for SCOPE Summit (Summit for Clinical Ops Executives) at Cambridge Innovation Institute. We will dive deep into the critical role of collaboration within the clinical research ecosystem. How do we bring together diverse stakeholders—sponsors, CROs, clinical trial tech innovators, suppliers, patients, sites, advocacy organizations, investors, and non-profits—to share best practices in trial design, program planning, innovation, and clinical operations? We’ll explore why it’s vital for thought leaders to step beyond their own organizations and learn from others, exchanging ideas that drive advancements in clinical research. Additionally, we’ll discuss the pivotal role of scientific conferences like SCOPE Summit in fostering these essential connections and collaborations, helping shape the future of clinical trials. Join us as we uncover how collective wisdom and cross-industry partnerships are transforming the landscape of clinical research.
