$176.3 million in cash, cash equivalents and short-term investments as of December 31, 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 reported financial results and operational highlights for the fourth quarter and year ended December 31, 2024.
"In 2025 we plan to continue advancing our gamma delta 1 CAR T cell therapy programs, achieving key milestones and reporting preliminary data in autoimmune and oncology indications," said Chen Schor, President and Chief Executive Officer of Adicet Bio. "The recent FDA Fast Track Designation for ADI-001 in refractory SLE with extrarenal involvement and in SSc highlights the significant unmet need for innovative, off-the-shelf therapies to treat autoimmune diseases. We are continuing to enroll LN patients in our ongoing Phase 1 trial in autoimmune diseases and look forward to sharing preliminary clinical data in the first half of 2025 and additional data in the second half of 2025. We expect to initiate enrollment for SLE, SSc, IIM and SPS patients in the second quarter and for AAV in the second half of the year, and to report clinical data from these additional cohorts in the second half as well."
Mr. Schor continued: "In addition, we are continuing to enroll patients in our Phase 1 trial of ADI-270 in relapsed or refractory metastatic/advanced ccRCC patients and remain on track to announce preliminary clinical data in the first half of 2025. With a strong clinical foundation and growing momentum, Adicet is well-positioned to transform treatment paradigms for patients battling autoimmune diseases and solid tumors."
Fourth Quarter 2024 and Recent Operational Highlights:
Autoimmune diseases
- Continuing to advance phase 1 trial of ADI-001 in autoimmune diseases . In November 2024, Adicet announced the dosing of the first patient in the Phase 1 trial evaluating ADI-001 in LN. Enrollment for SLE, SSc, IIM, and SPS patients is expected to commence in the second quarter of 2025, with the initiation of AAV patient enrollment anticipated in the second half of 2025. The Company remains on track to share preliminary clinical data from the trial's LN cohort in the first half of 2025. Additional LN clinical data and preliminary clinical data from other autoimmune patient cohorts are anticipated in the second half of 2025, subject to study site initiation and patient enrollment.
- Fast Track Designation for ADI-001. In February 2025, Adicet received Fast Track Designation for ADI-001 for the treatment of refractory SLE with extrarenal involvement and SSc.
- ADI-001 clinical biomarker data presented at the American College of Rheumatology (ACR) Convergence 2024. In November 2024, Adicet showcased an oral abstract at the ACR Convergence 2024 detailing ADI-001 clinical biomarker data. The findings demonstrated significant chimeric antigen receptor (CAR) T cell activation, robust tissue trafficking and complete CD19+ B cell depletion in secondary lymphoid tissue, underscoring ADI-001's potential as a best-in-class off-the-shelf cell therapy for autoimmune diseases.
Solid tumor indications
- First patient dosed in phase 1 trial of ADI-270 in metastatic/advanced ccRCC. In December 2024, Adicet announced the dosing of the first patient in the Phase 1 clinical trial evaluating the safety and efficacy of ADI-270 in adults with relapsed or refractory metastatic/advanced ccRCC. Preliminary clinical data from the trial are anticipated in the first half of 2025.
- Presentation of ADI-270 data at the Society for Immunotherapy of Cancer (SITC) 2025 Spring Scientific Meeting. In March 2025, Adicet will present two posters highlighting ADI-270 preclinical data at the SITC 2025 Spring Scientific Meeting taking place March 12-14 in San Diego, CA.
Corporate updates
- Appointed Julie Maltzman, M.D., as Chief Medical Officer. In December 2024, Adicet appointed Julie Maltzman, M.D., as Chief Medical Officer, who brings over two decades of experience in clinical development and regulatory affairs to the Company's leadership team. Dr. Maltzman's expertise spans across oncology and autoimmune diseases, encompassing all phases of drug development from early-stage research to global regulatory approvals and commercialization. Dr. Maltzman is leading Adicet's clinical development functions to advance the company's pipeline of allogeneic gamma delta CAR T cell therapies.
