A Phase 1 Safety and Efficacy Study of ADI-001 Anti-CD20 CAR-engineered Allogeneic Gamma Delta (γδ) T Cells in Adults With B Cell Malignancies

Description

This is a Phase 1 dose escalation study following a 3+3 study design. The purpose of this study is to evaluate the safety and efficacy of ADI-001 in patients with B cell malignancies.ADI-001 is an investigational immunotherapy composed of allogeneic gamma delta T cells that is being evaluated as a potential treatment for patients diagnosed with B cell malignancies who have relapsed or are refractory to at least two prior regimens. This first-in-human study will assess the safety and tolerability of ADI-001 and is designed to determine the maximum tolerated dose (MTD) or maximum assessed dose (MAD). Patients will be administered a single infusion or multiple infusions of ADI-001 cells. The study will include the following two parts: Part 1 : dose escalation and extension. Parts 1a (escalation) and 1b (extension) will involve escalation and administration of single dose of ADI-001 and multiple doses of ADI-001. Part 2 : dose expansion will involve dose administration of ADI-001 at MTD/

Current or history of any of the following conditions: 1. Central nervous system (CNS) primary lymphoma (current or history) 2. Unrelated malignancy requiring systemic treatment (current or history \[in the past 3 years, other than hormonal treatment which is allowed\]) 2. Any of the following current conditions: 1. Active acute or chronic graft versus host disease (GvHD) other than grade 1 with skin involvement, or GvHD requiring immunosuppressive treatment within 4 weeks of enrollment 2. Any other acute or chronic medical or psychiatric condition that may increase the risk associated with study participation or investigational product administration 3. Tumor mass effects such as bowel obstruction or blood vessel compression that require therapy 4. Opportunistic infections 3. History of any clinically significant conditions in the opinion of the Investigator 4. Prior treatment with any of the following: a Gene therapy, genetically modified cell therapy, or adoptive T cell therapy within 6 weeks of study enrollment. b Radiation therapy within 4 weeks prior to study entry.
