Summary
Brief summary (as posted)
This study is a phase I-II clinical trial of CAR-NK cell therapy for high-risk lymphoma patients with primary Sjogren's syndrome (pSS). The aim is to determine the optimal dose of CAR-NK cells and evaluate the safety and efficacy of increasing doses of iC9/CAR19/IL15 CB-NK cell therapy. Use i3+3 based design to increase dosage. Dose limiting toxicity (DLT) is defined as the occurrence of CRS within 2 weeks after cell infusion, requiring transfer to the intensive care unit, or grade III-IV acute graft-versus-host disease within 40 days after infusion, or grade 3-5 allergic reactions related to CAR-NK cell infusion. For the purpose of i3+3 design, efficacy is defined as a reduction in the high-risk of lymphoma in pSS patients and at least partial relief of dry mouth and eye symptoms on the 30th day after CAR-NK cell infusion.

- description
- The dose escalation method adopts the i3+3 design, and CAR-NK cells are tentatively given three doses based on literature: 5×10\^6/kg body weight, 1×10\^7/kg body weight, and 5×10\^7/kg body weight. Plan to enroll 6-12 subjects. Researchers can together decide whether to increase it to a higher dose to determine the possible therapeutic dose. During the experiment, dosage adjustments can be made based on the safety and tolerability data of the subjects, including limiting toxicity type, incidence, and severity of dose limiting toxicity (DLT).
