入选标准
- •Signed informed consent form.
- •Patient is ≥18 years of age.
- •Patient is willing and able to adhere to the protocol requirements.
- •Patient is willing and able to adhere to the protocol requirements.
- •Patient with diagnosis of MM who has been treated with at least 2 prior lines of treatment, including at least one cycle of high-dose chemotherapy with autologous hematopoietic stem cell transplantation if the patient was eligible, and exposure to an immunomodulatory imide drug (e.g. lenalidomide and/or pomalidomide), a proteasome inhibitor, and an anti-CD38 antibody. (Note: Induction therapy, up to 2 cycles of high-dose chemotherapy with autologous hematopoietic stem cell transplantation, and subsequent consolidation and/or maintenance therapy are considered one line of treatment).
- •At least one of the following subcriteria must be measured in the patient: - Serum M-protein greater or equal to 0.5 g/dL - Urine M-protein greater or equal to 200 mg/24 h - Serum free light chain (FLC) assay: involved FLC level greater or equal to 10 mg/dL (100 mg/L) provided serum FLC ratio is abnormal - A biopsy-proven evaluable plasmacytoma - Bone marrow plasma cells >10% of total bone marrow cells (>30% if bone marrow plasma cells are the only marker of measurable disease)
- •Patients previously treated with an anti-SLAMF7 antibody are eligible.
- •Karnofsky performance status ≥60%. If patient has a Karnofsky performance status <60% (e.g. after a spinal cord injury) but is judged to be medically fit by the investigator, patient is eligible.
- •Female patients of childbearing potential must: a) have a negative pregnancy test (blood) at screening. b) either commit to true abstinence from heterosexual contact or agree to use, and be able to comply with, effective measures of contraception without interruption, from screening through 1 year following the IMP infusion. A highly effective method of contraception or birth control (failure rate less than 1% per year when used consistently and correctly) must be practiced. The patient should be informed of the potential risks associated with becoming pregnant while enrolled in this clinical trial. Reliable methods for this trial are: combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal), progestogenonly hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable), intrauterine device, intrauterine hormone-releasing system, bilateral tubal occlusion, sexual abstinence or vasectomized sexual partner. Abstinence is only accepted as true abstinence: when this is in line with the preferred and usual lifestyle of the patient. (Periodic abstinence [e.g. calendar, ovulation, symptothermal, post-ovulation methods and withdrawal] are not acceptable methods of contraception.) Postmenopausal (no menses for at least 1 year without alternative medical cause) or surgically sterile female patients (tubal ligation, hysterectomy or bilateral oophorectomy) may be enrolled. c) Agree to abstain from breast feeding during the study participation and for 1 year after the IMP infusion.
- •Male patients must practice true abstinence or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential for at least 1 year after IMP infusion, even if he has undergone a successful vasectomy.

- •Pregnant or lactating women.
- •Current or previous (within 30 days of enrollment) treatment with another IMP.
- •Known abuse of alcohol, drugs, or medicinal products.
- •Employees of the sponsor, or employees or relatives of the investigator.
- •Patient has undergone a prior allogeneic stem cell transplant with either standard or reduced intensity conditioning >12 months, and suffers on chronic Graft-versus-Host Disease and/or is on systemic immune-suppressants.
- •Patient with diagnosis of MM a. in first relapse following an autologous stem cell transplantation or b. in second relapse that subsequently achieves a complete response that is considered being a candidate for an allogeneic stem cell transplantation, unless the patient explicitly denies undergoing an allogeneic stem cell transplantation.
- •Patient has received anti-CD38 and/or anti-SLAMF7 antibodies ≤8 weeks prior to leukapheresis.
- •Ongoing treatment with systemic immune-suppressants (e.g. systemic cyclosporine or systemic steroids at any dose). (Note: Physiologic steroid replacement therapy, topical immunesuppresants as e.g. cyclosporine/tacrolimus eye drops, and topical steroids are permitted.)
- •Echocardiogram with left ventricular ejection fraction <45%.
- •Inadequate renal function defined by creatinine clearance ≤45 mL/min using Cockcroft-Gault equation.
- •Inadequate hepatic function defined by aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) >2.5 x upper limit of normal (ULN) and total bilirubin >1.5 x ULN (unless due to Gilbert's syndrome and direct bilirubin is ≤1.5 x ULN; unless due to intrahepatic myeloma lesions as demonstrated by magnetic resonance imaging [MRI] or positron emission tomography [PET]/computed tomography [CT] not older than 4 weeks prior to screening).
- •International ratio (INR) or partial thromboplastin time (PTT) >1.5 x ULN, unless on a stable dose of anti-coagulant.
