HCC: Hepatocellular carcinoma; mCRPC: Metastatic castration-resistant prostate cancer; MICA/MICB: Major histocompatibility complex (MHC) Class I chain-related protein A/B; NHL: Non-Hodgkin's lymphoma; PSMA: Prostate-specific membrane antigen; RCC: Renal cell carcinoma; ST: Solid tumor; ULBP: UL16 binding protein

Adicet Bio 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.


Our lead product candidate, ADI-001, is a first-in-class investigational allogeneic gamma delta CAR T cell therapy currently being developed in two indications. It’s being studied in an ongoing Phase 1 trial for the treatment of relapsed or refractory aggressive B-cell NHL and in a Phase 1 study in lupus nephritis (an autoimmune disease caused by systemic lupus erythematosus (SLE)).

In Autoimmune Diseases

ADI-001 is ideally suited for the treatment of autoimmune diseases given its robust B-cell depletion consistent with other autologous CAR T therapies tested in autoimmune diseases, its tissue tropism potential, and the safety data observed in our oncology Phase 1 study.

FDA cleared the IND application for ADI-001 in lupus nephritis in December, 2023. Adicet plans to initiate a Phase 1 study to evaluate the safety and efficacy of ADI-001 in lupus nephritis in Q2 2024.

In Cancer

ADI-001 targets malignant B-cells with an anti-CD20 CAR via the gamma delta innate and T cell endogenous cytotoxicity receptors. Gamma delta T cells engineered with an anti-CD20 CAR have demonstrated potent antitumor activity in preclinical models, leading to long-term control of tumor growth.

ADI-001 has shown encouraging early efficiacy and favorable safety in heavily pretreated aggressive NHL patients in initial Phase 1 clinical studies.

In April 2022, ADI-001 was granted Fast Track Designation by the U.S. Food and Drug Administration (FDA) for the potential treatment of relapsed or refractory B-cell NHL.



  • ADI-270, an armored CD70 CAR γδ T cell targeting CD70 via the CD27-ligand, has shown superiority to scFv (single-chain variable fragment) CARs1
  • Innate and adaptive targeting mechanisms associated with activity in solid tumors such as renal cell carcinoma (RCC) and other indications
  • Armoring via dominant negative receptor; addresses TGFβ in Tumor Microenvironment
  • Lead CAR demonstrated potency and improved serial killing, and resilience against suppressive factors and graft vs host rejection
  • Homing and activity of gamma delta 1 T cells demonstrated in RCC

Armored PSMA CAR Gamma Delta T Cell Program

  • Potent CAR construct active against heterogeneous PSMA
  • Three mechanisms of action designed to address tumor heterogeneity
  • Homing of gamma delta 1 T cells documented in mCRPC
  • Inclusion of armoring to address suppressive TME
  • No significant CRS and ICANS demonstrated with Adicet CAR gamma delta 1 T cells in clinical trials reported to-date

Expanded Access Policy

Expanded Access refers to the use of an investigational therapy outside of a clinical trial for potential treatment of a serious or life-threatening condition. Adicet is a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer. Consistent with our commitment to bring innovative, safe, and effective therapies to patients, we are focused on conducting the clinical trials necessary to gain regulatory approvals to make our therapies available to patients as quickly as possible. Participation in one of our clinical trials is the best way to access Adicet gamma delta T cell investigational therapies. As such, Adicet does not provide access to our investigational therapies on an Expanded Access basis at this time.

We encourage patients interested in our investigational therapies to learn more about our ongoing studies by visiting Treating physicians may request additional information about Adicet’s Expanded Access policy by contacting
