What Adicet Bio, Inc. does

In the company’s own words

Adicet Bio, Inc. (Nasdaq: ACET) is a clinical-stage biotechnology company developing allogeneic gamma delta T-cell therapies for autoimmune diseases and cancer. Its engineered, donor-derived cells are designed as “off-the-shelf” treatments, with prulacabtagene leucel (prula-cel), a CD20-targeting CAR T-cell candidate, in Phase 1 studies for autoimmune conditions including lupus nephritis, systemic lupus erythematosus, systemic sclerosis and rheumatoid arthritis. The company is also advancing ADI-212, a gene-edited, IL-12-armored candidate targeting PSMA for metastatic castration-resistant prostate cancer; development of its ADI-270 candidate for renal cancer has been discontinued. Adicet uses a proprietary platform to activate and expand Vδ1 gamma delta T cells from unrelated donors, engineer them with CARs and manufacture them for potential use across patients. Its pipeline also includes discovery and preclinical programs for autoimmune diseases, hematological malignancies and solid tumors. The company acquired Applied Immune Technologies in 2016, adding intellectual property and establishing its wholly owned Adicet Bio Israel subsidiary. Its website is https://www.adicetbio.com.
