Inclusion criteria
. Age ≥ 18 years；
. Diagnosis of multiple myeloma (MM) confirmed according to the IMWG diagnostic criteria, with BCMA expression on MM cells determined by flow cytometry or pathology immunohistochemistry;
. Previously treated with at least 2 lines of anti-MM therapy, with at least 1 complete treatment cycle for each line, and evidence of disease progression within 12 months after the most recent anti-myeloma treatment, or being refractory to both immunomodulatory drugs and proteasome inhibitors, with disease progression within 2 months after the most recent anti-myeloma treatment (according to the IMWG diagnostic criteria);
. Disease must be measurable at screening, meeting at least one of the following criteria:Serum M-protein level ≥ 0.5 g/dL; Urinary M-protein level ≥ 200 mg/24h; Serum involved free light chain ≥ 10 mg/dL and an abnormal serum free light chain κ/λ ratio; clinical relapse: a. New bone lesions or soft tissue plasmacytomas (excluding osteoporotic fractures); b. Confirmed increase (≥ 50% increase in SPD of measurable lesions with an absolute value of ≥ 1 cm) in pre-existing plasmacytomas or bone lesions.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Cytokine release syndrome (CRS)
Timeframe: up to Day 28 post-infusion
2
Dose-limiting toxicities (DLTs)
Timeframe: Dose-limiting toxicities (DLTs) are evaluated between the infusion and 28 days post-infusion.
. ECOG score 0-2, with an expected survival time ≥ 3 months;
. Bone marrow function at screening (or within 2 months prior to screening) meets the following criteria: a.Hemoglobin ≥ 6 g/dL (no red blood cell transfusion within 1 week before screening), recombinant human erythropoietin is allowed; for patients who meet the ≥6 g/dL criterion at screening, red blood cell transfusion is allowed to maintain hemoglobin ≥ 6 g/dL; b.Absolute neutrophil count (ANC) ≥ 600/μL (no use of granulocyte colony-stimulating factor (G-CSF) within 1 week or pegylated G-CSF within 2 weeks prior to screening); c. Platelet count ≥ 50,000/μL; d. Lymphocyte count ≥ 500/μL; e. Absolute CD3-positive T cell count ≥ 150/μL;
. Renal function at screening (or within 2 months prior to screening) should be normal, with a creatinine clearance ≥ 45 mL/min;
. Liver function at screening (or within 2 months prior to screening) must meet the following criteria: a.
