Testing ADI-001 in people with treatment-refractory rheumatoid arthritis

Official title: A Phase 1 Study of ADI-001 Anti-CD20 CAR-engineered Allogeneic Gamma-Delta (γδ) T Cells in Adults With Treatment-refractory Rheumatoid Arthritis

Run by Adicet Therapeutics · NCT07100873 · Data updated 2026-11-12

This Phase 1 test will try ADI-001 with two different pre-treatment (lymphodepletion) regimens in adults whose rheumatoid arthritis has not improved with standard therapies.

Is this trial a fit for you?

Likely a good fit

Adults (age ≥18) who meet the 2010 ACR-EULAR RA criteria, have disease refractory to standard treatments, have adequate blood, liver, cardiac and lung function, and agree to lymphodepletion and extended safety follow-up are the ideal candidates.

Probably not a fit

People with severe liver disease (Child-Pugh B or C), those requiring high-dose corticosteroids, those with recent clinically significant infections, or those unwilling to undergo long-term safety monitoring are unlikely to be eligible or to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a randomized, single-blind, parallel-group Phase 1 trial that compares two different lymphodepletion regimens given before ADI-001 in adults with treatment-refractory rheumatoid arthritis. The trial includes screening, a lymphodepletion (LD) period using agents such as fludarabine and cyclophosphamide, administration of ADI-001, and a follow-up/safety monitoring period. The primary focus is early safety and tolerability and to compare the two LD approaches; efficacy signals will be exploratory. The study is sponsored by Adicet Therapeutics and conducted at a single site in Shanghai.

Why it matters

Potential benefit: If successful, ADI-001 could provide a new treatment option for people with rheumatoid arthritis that has not responded to existing therapies.

How similar studies have gone: Lymphodepletion followed by cellular immunotherapies has shown promising signals in early trials for some autoimmune conditions, but this strategy remains experimental in RA with limited published efficacy data.

Inclusion Criteria:

1. ≥ 18 years of age.
2. Fulfills the 2010 ACR-EULAR RA classification criteria
3. Agreement not to take traditional medicines and medications not prescribed by a doctor
4. Adequate hematological, liver, cardiac and pulmonary function

Exclusion Criteria:

1. Presence of severe liver disease, Child-Pugh class B or C.
2. Autoimmune disease requiring prednisone higher than 0.5 mg/kg/day (or corticosteroid equivalent).
3. Subjects unwilling to participate in an extended safety monitoring period (LTFU protocol)
4. History of a clinically significant infection (including sepsis, pneumonia, bacteremia, fungal, viral and opportunistic infections) within 4 weeks prior to first dose of study drug which in the opinion of the Investigator may compromise the safety of the subject in the study.
