Adicet Opens Enrollment for ADI-270 Phase 1 Clinical Trial in Metastatic/Advanced Clear Cell Renal Cell Carcinoma
First gamma delta CAR T cell therapy with the potential to address solid tumors entering clinical trials
Preliminary Phase 1 clinical data expected in the first half of 2025
REDWOOD CITY, Calif. & BOSTON – November 18, 2024 – Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer, today announced the opening of enrollment for the Phase 1 clinical trial evaluating ADI-270 in patients with metastatic/advanced clear cell renal cell carcinoma (ccRCC).
“Solid tumors represent one of the highest unmet medical needs in oncology and have yet to benefit from the breakthroughs observed with CAR T cell therapies in hematologic malignancies. Emerging data from ADI-270, our armored allogeneic “off the shelf” gamma delta 1 CAR T cell therapy targeting CD70 positive cancers, have shown potential in addressing this gap,” said Chen Schor, President and Chief Executive Officer. “At the recent ASGCT conference, we presented preclinical data in which ADI-270 demonstrated significant tumor infiltration, resistance to the immunosuppressive tumor microenvironment, and potent activity via CAR and innate-mediated targeting, highlighting its potential for treating solid tumors. We look forward to enrolling patients and anticipate sharing preliminary clinical data from the trial in the first half of 2025.”
About the Phase 1 Trial
The Phase 1 multicenter, open-label clinical trial is designed to investigate ADI-270 as monotherapy in adults with relapsed or refractory ccRCC. Following lymphodepletion, patients will be eligible to receive a single dose of ADI-270 with a starting dose level of 3E8 CAR+ cells. Subject to meeting protocol defined criteria, patients enrolled in the trial may be eligible to receive a second dose of ADI-270. The dose escalation and dose expansion portions of the trial will evaluate safety, tolerability, and pharmacokinetics as well as anti-tumor activity as assessed by overall response rate, duration of response and disease control rate.
About ADI-270
ADI-270 is an armored allogeneic “off-the-shelf” gamma delta CAR T cell therapy candidate targeting CD70-positive cancers. CD70 is a compelling target due to its high
expression in both solid and hematological malignancies. ADI-270 is engineered with a third-generation CAR designed to target CD70 using its natural receptor, CD27, as the binding moiety and is further armored with a dominant negative form of the transforming growth factor-β receptor II (dnTGFβRII) to provide functional resilience to the immunosuppressive tumor microenvironment. ADI-270 is also designed to increase exposure and persistence by reducing susceptibility to host vs. graft elimination. These properties of ADI-270 combined with the potent tumor infiltration demonstrated with gamma delta 1 T cells aim to improve clinical responses of RCC patients and other patients with CD70+ tumors.
About Renal Cell Carcinoma
Renal cell carcinoma (RCC) is the most common tumor of the kidney, constituting 80% to 85% of primary renal neoplasms. Clear cell RCCs (ccRCC) are the most common subtype, accounting for 80% of all RCCs. ccRCC is an aggressive subtype arising from renal stem cells commonly arising in the proximal nephron and tubular epithelium, and often metastasizes to the lungs, liver, and bones. Approximately 20% of newly diagnosed cases of RCC are locally advanced or metastatic and up to 30% of patients will develop metastatic disease following nephrectomy. While the 5-year survival rate for localized RCC is 93%, the 5-year survival rate for advanced disease is 15%.
About Adicet Bio, Inc.
Adicet Bio, Inc. is a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer. Adicet is advancing a pipeline of “off-the-shelf” gamma delta T cells, engineered with chimeric antigen receptors (CARs), to facilitate durable activity in patients.

Adicet Bio Announces First Lupus Nephritis Patient Dosed in Phase 1 Clinical Trial of ADI-001 in Autoimmune Diseases
Enrollment underway for lupus nephritis (LN) patients
Preliminary clinical data in LN anticipated in 1H25
Initiation of patient enrollment in systemic lupus erythematosus (SLE), systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM) and stiff person syndrome (SPS) expected in 1Q25; patient enrollment in anti-neutrophil cytoplasmic autoantibody (ANCA) associated vasculitis (AAV) expected in 2H25
REDWOOD CITY, Calif. & BOSTON – November 18, 2024 – Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer, today announced that the first LN patient has been dosed in the Phase 1 clinical trial evaluating ADI-001 in autoimmune diseases.
“Dosing the first lupus nephritis patient in our Phase 1 trial of ADI-001 marks an important step forward in our mission of improving the lives of patients affected by autoimmune diseases, particularly lupus nephritis,” said Francesco Galimi, M.D., Ph.D., Senior Vice President and Chief Medical Officer of Adicet Bio. “With clinical biomarker data from our study in non-Hodgkin’s lymphoma demonstrating robust tissue trafficking and complete CD19+ B cell depletion in peripheral blood and secondary lymphoid tissue, ADI-001 has the potential to be a transformative off-the-shelf treatment option for several autoimmune diseases. Additionally, the FDA’s Fast Track Designation to ADI-001 in relapsed/refractory class III or class IV LN and the clearance of our investigational IND amendment application of ADI-001 for the treatment of SPS and IIM further serves to emphasize the broad and urgent unmet need for approved therapies to address autoimmune diseases.”
Dr. Galimi continued, “With clinical sites open for enrollment and additional sites that are expected to open in the near future, we anticipate sharing preliminary clinical data from the trial in the first half of 2025. In addition, we look forward to initiating enrollment for SLE, SSc, IIM, and SPS patients in the first quarter of 2025 and for AAV patients in the second half of 2025."
About ADI-001
ADI-001 is an investigational allogeneic gamma delta CAR T cell therapy targeting B-cells via an anti-CD20 CAR. ADI-001 was granted Fast Track Designation by the FDA for the potential treatment of relapsed/refractory class III or class IV lupus nephritis.
About the Phase 1 Trial
The Phase 1 study has four separate arms, enrolling LN and SLE patients into one arm, SSc patients into a second arm, IIM and SPS patients in a third arm and AAV patients into a fourth arm. Enrolled patients will receive a single dose of ADI-001. The dose-limiting toxicity window is 28 days with response and safety assessments conducted on Day 28 and during the follow up period on months 3, 6, 9, 12, 18 and 24. The primary objectives of the study are to evaluate the safety and tolerability of ADI-001. Secondary objectives include measuring cellular kinetics, pharmacodynamics, changes in autoantibody titers, and appropriate disease activity scores in each indication.
