About this trial

This study is an open-label, single-arm, prospective clinical trial involving patients with relapsed/refractory B-cell lymphoma, aimed at evaluating the safety and efficacy of CAR-T cell infusion.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

1. The participant has given consent and signed the informed consent form, and is willing and able to comply with the planned visits, research treatments, laboratory tests, and other trial procedures;

Anti-CD20 monoclonal antibody;

Combination chemotherapy containing anthracyclines.

3. Age 18 or older, both men and women are eligible;

Disqualifiers

1. Severe heart failure or left ventricular ejection fraction <50%;

2. History of severe pulmonary function impairment;

3. Concurrent other malignant tumors in the progressive stage;

4. Concurrent severe infection that cannot be effectively controlled;

Trial design

Design model

Single group

Treatments tested in this trial

  • CY-219 CAR-T

    Drug

    Eligible participants should receive preconditioning 5 to 3 days before CAR-T cell infusion. The recommended preconditioning regimen is fludarabine (30 mg/m²/day, for 3 consecutive days) and cyclophosphamide (300 mg/m²/day, for 3 consecutive days) (Flu/Cy). Thirty minutes before infusion, prophylactic medication for allergic reactions should be administered: 25 mg of promethazine hydrochloride or 12.5 mg of diphenhydramine, either intramuscularly or orally. A '3+3' dose-escalation study design will be used, aiming to recruit 9-18 subjects with relapsed/refractory B-cell lymphoma.

CAR-T single-cell phenotype and clonal characteristics

CY-219 CAR-T cell infusion product and the in vivo CAR-T single-cell phenotype, clonal characteristics of research participants, as well as other indicators of interest to researchers, such as cytokine profiles.

Time frame
Test the product on the day of infusion. Follow-up will be conducted on day 10 and day 28 after infusion. From the 2nd month to the 3rd month, follow-up will be conducted once a month; from the 6th month to the 1st year, follow-up will be conducted once
