ADI-001 is also being evaluated in a phase 1 study in patients with B-cell non-Hodgkin lymphoma.
Adicet Bio has received Fast Track Designation for its allogeneic gamma delta T cell therapy ADI-001 for treating relapsed/refractory class III or class IV lupus nephritis, joining the race of clinical-stage candidates being developed for autoimmune diseases.1
“The FDA’s decision to grant ADI-001 Fast Track Designation for lupus nephritis underscores the urgent need for new therapies for this chronic disease,” Chen Schor, President and Chief Executive Officer, Adicet Bio, said in a statement.1 “We plan toinitiate our Phase 1 clinical study in lupus nephritis later this month. With clinical data for ADI-001 in non-Hodgkin’s lymphoma demonstrating CD19+ B-cell depletion that mirrors data by autologous alpha-beta chimeric antigen receptor (CAR) T in academic clinical studies in several autoimmune diseases, we believe we are well positioned to expand our autoimmune program to address additional indications beyond lupus nephritis. We look forward to providing a comprehensive update on our autoimmune program to investors in the near term.”
Adicet originally developed ADI-001 for the treatment of relapsed or refractory aggressive B-cell non-Hodgkin lymphoma (NHL), for which it is being evaluated in a phase 1 study (NCT04735471). The company announced positive interim data from the study in June 2023, boasting an overall complete response (CR) rate of 63%, a 6-month CR rate of 25%, and a CR rate of 67% and 6-month CR rate of 33%in patients whose disease had progressed after CD19 CAR T-cell therapy.2
“We plan to transition the ADI-001 program into a potential pivotal Phase 2 study in post-CAR T LBCL in the first half of 2024. In addition, we expect to provide a clinical update which will include efficacy, 6-month CR rate, and safety data, from additional post-CAR T LBCL patients in the second half of 2024,” Francesco Galimi, MD, PhD, Senior Vice President and Chief Medical Officer of Adicet Bio, noted in a statement.2

In other recent news in the lupus space, Cabaletta Bio’s CABA-201, an investigational CD19-directed CAR T-cell therapy, recently demonstrated initial safety data in participants with systemic lupus erythematosus (SLE) and lupus nephritis in the phase 1/2 RESET-SLE clinical trial (NCT06121297). The first patients dosed have completed their 28-day dose-limiting toxicity observation window after receiving the CAR-T, with neither patient showing evidence of any grade cytokine release syndrome (CRS) or immune effector cell-associated neurotoxicity syndrome (ICANS).
“With no CRS or ICANS of any grade observed in either of the first patients from the RESET-Myositis and RESET-SLE trials, we look forward to presenting initial translational and clinical data from both patients during a satellite symposium at the EULAR 2024 Congress on June 14th,” Steven Nichtberger, MD, the chief executive officer and cofounder of Cabaletta, said in a statement.3
