Adicet Bio (ACET) FY Conference Transcript

Summary of Adicet Bio (ACET) FY Conference Call - August 12, 2025 Company Overview - Company: Adicet Bio (ACET) - Focus: Leader in off-the-shelf gamma delta CAR T cell therapies, particularly for autoimmune diseases and solid tumors [3][4] Core Points and Arguments Allogeneic Approach - Adicet's gamma delta CAR T cell therapies are off-the-shelf, providing a differentiated safety profile compared to autologous therapies [4][8] - The ability to dose in outpatient settings is a significant advantage, especially for autoimmune diseases that often lead to organ damage [4][9] Autoimmune Disease Programs - Current programs include enrollment for systemic lupus erythematosus (SLE), lupus nephritis (LN), and systemic sclerosis [5][28] - The company is targeting CD20 instead of CD19 or CD22 due to its stable antigen presence on B cells, which has shown similar efficacy in B cell depletion [12][13] Safety and Efficacy - Gamma delta T cells have a lower frequency of cytokine release syndrome (CRS) and neurotoxicity compared to alpha beta T cells, allowing for safer outpatient administration [9][10] - The potential for patients to avoid prolonged immunosuppression before treatment is a key benefit of the allogeneic approach [17][18] Clinical Study Design - The lupus nephritis study is designed to enroll patients and report outcomes at various intervals, with a focus on safety and B cell depletion [29][39] - Initial readout expected to include at least six patients with three months of follow-up, assessing safety, immune reset, and renal function [38][40] Comparison of Study Types - Investigator-sponsored studies (ISTs) are more subjective and less rigorous compared to company-sponsored studies, which are multisite and have defined protocols [20][22] - Company-sponsored studies are viewed as more reliable for understanding patient benefits [23] Future Developments - The prostate cancer program (ADI 212) is in development, focusing on enhancing gamma delta T cell efficacy in solid tumors through gene editing and other technologies [45][46] - Manufacturing capabilities are robust, with a 14-day process and multiple sources for donor material, allowing for significant scalability [49][52] Important but Overlooked Content - The mean age of death for patients with SLE is 55, highlighting the urgent need for effective therapies that can reduce reliance on immunosuppressants and steroids [25] - The potential for patients to achieve immunosuppressant-free remission is a significant therapeutic goal, representing a major advancement in treatment [25][26] Conclusion Adicet Bio is positioned to make significant advancements in the treatment of autoimmune diseases and solid tumors through its innovative allogeneic gamma delta CAR T cell therapies, with ongoing clinical trials and a strong focus on safety and efficacy. The company’s approach addresses critical challenges in current therapies, particularly in terms of patient management and treatment accessibility.
