Brief Summary

This is a single arm, single center clinical study evaluating the safety and efficacy of CAR-T treatment for multiple myeloma.

Detailed Description

This study is a single arm, single center study targeting patients with recurrent/refractory multiple myeloma (r/rMM). The study plans to enroll 40 subjects, with a sample size based on actual occurre...

Eligibility Criteria

Inclusion

  • Patients or their guardians understand and voluntarily sign the informed consent form, and are expected to complete the follow-up examination and treatment of study procedures;
  • Aged 18-75 years, male or female;
  • According to IMWG diagnostic criteria, diagnosed with multiple myeloma;
  • Patients with documented multiple myeloma disease as relapsed refractory or primary refractory, defined as: a) relapsed refractory: no response to salvage therapy (no response defined as failure to achieve minimal response \[MR\] or disease progression on treatment), or disease progression within 60 days of the last treatment, or disease progression in patients who have achieved MR or above remission; b) primary refractory: never achieved MR or above response to any treatment, including never achieved MR or above remission, but M protein changes are not large, patients without evidence of clinical progression and patients who have primary refractory, progressed, and met the definition of progression.
  • the presence of measurable disease at screening as determined by any of the following criteria: serum monoclonal paraprotein (M-protein) level ≥ 1.0 g/dL or urine M-protein level ≥ 200 mg/24 hours; or diagnosis of light chain multiple myeloma without measurable disease in serum or urine: serum immunoglobulin free light chain ≥ 10 mg/dL and abnormal serum immunoglobulin κ/γ free light chain ratio; extramedullary measurable disease; the presence of tumor cells in the bone marrow as detected;
  • the patient has recovered from the toxicity of previous treatment, that is, CTCAE toxicity grade \< 2 (unless the abnormality is tumor-related or judged by the investigator to be stable, it has little effect on safety or efficacy);
  • ECOG performance status score 0 to 2 and expected survival greater than 3 months;
  • Appropriate organ function:
  • alanine aminotransferase (ALT) ≤ 3 times the upper limit of normal (ULN); aspartate aminotransferase (AST) ≤ 3 times the ULN; total bilirubin ≤ 1.5 times the ULN; Serum creatinine ≤ 1.5 times ULN, or creatinine clearance ≥ 30 mL/min (calculated by Cockcroft-Gault formula); Intraventricular oxygen saturation ≥ 92%; Left ventricular ejection fraction (LVEF) ≥ 45%, no pericardial effusion confirmed by echocardiography, no clinically significant electrocardiographic findings; no clinically significant pleural effusion; 9. venous access for collection can be established, no contraindications for leukocyte collection.

Exclusion

  • Diagnosis or treatment of another invasive malignancy other than multiple myeloma within 3 years, with the following exceptions: malignancy treated with curative intent and no known active disease ≥ 3 years prior to enrollment; or adequately treated non-melanoma skin cancer with no evidence of disease;
  • previous anticancer therapy (prior to blood collection for CAR-T preparation) as follows: targeted therapy, epigenetic therapy, or investigational agent within 14 days or at least 5 half-lives (whichever is shorter), or invasive investigational medical devices; monoclonal antibody therapy within 21 days; proteasome inhibitor therapy within 14 days; immunomodulator therapy within 7 days; and radiotherapy within 14 days (except for bone marrow reserve with ≤ 5% field coverage);
  • Any hematopoietic stem cell transplantation within 2 months before screening;
  • History of central nervous system diseases;
  • known active central nervous system (CNS) involvement or clinical signs of meningeal involvement in multiple myeloma;
  • Waldenström macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal proteinopathy, and skin changes) or primary AL amyloidosis at screening;
  • Hepatitis B surface antigen (HBsAg) positive, or hepatitis B core antibody (HBcAb) positive and peripheral blood HBV DNA quantitative detection positive; hepatitis C virus (HCV) antibody positive; human immunodeficiency virus (HIV) antibody positive; cytomegalovirus (CMV) DNA detection positive; syphilis detection positive; Epstein-Barr virus DNA detection positive;
  • Patients with a history of severe allergy \[a history of severe allergy is defined as a secondary or above allergic reaction, any of the following clinical manifestations occur when allergic reactions occur: airway obstruction (runny nose, cough, wheezing, dyspnea), tachycardia, hypotension, arrhythmia, gastrointestinal symptoms (nausea, vomiting), incontinence, laryngeal edema, bronchospasm, cyanosis, shock, respiratory, cardiac arrest\] or known allergy to any of the active ingredients, excipients or murine products and xenogeneic proteins contained in this trial (including Qinglin regimen);
  • Patients with severe heart disease, including but not limited to severe arrhythmia, unstable angina pectoris, massive myocardial infarction, New York Heart Association class III or IV cardiac insufficiency, myocardial infarction ≤ 6 months before screening or coronary artery bypass grafting (CABG), a history of unexplained syncope and non-vasovagal or dehydration caused by, a history of severe non-ischemic cardiomyopathy, refractory hypertension (refractory hypertension is defined as: the use of reasonable tolerable adequate doses of ≥ 3 antihypertensive drugs (including diuretics) on the basis of lifestyle improvement for \> 1 month of blood pressure is still not up to standard or taking ≥ 4 antihypertensive drugs blood pressure can be effectively controlled);
  • unstable systemic diseases judged by the investigator: including but not limited to severe liver, kidney or metabolic diseases requiring drug treatment;
  • Patients with acute/chronic graft-versus-host disease (GVHD) within 6 months before screening, or need to receive immunosuppressive agents for GVHD;
  • Patients with active autoimmune or inflammatory diseases of the nervous system (e.g., Guillain-Barre syndrome (GBS), amyotrophic lateral sclerosis (ALS)) and clinically significant active cerebrovascular disease (e.g., cerebral edema, posterior reversible encephalopathy syndrome (PRES));
  • Neoplastic emergencies (such as spinal cord compression, intestinal obstruction, leukostasis, tumor lysis syndrome, etc.) requiring emergency treatment before screening or reinfusion;
  • presence of uncontrollable bacterial, fungal, viral, or other infections requiring antibiotic therapy;
  • Hematopoietic cytokine drugs that have been transfused or have an effect on the hemogram of patients such as erythropoietin (EPO), granulocyte colony-stimulating factor (G-CSF), and granulocyte-macrophage colony-stimulating factor (GM-CSF) within 2 weeks of blood collection scheduled for CAR-T preparation at screening, and have an effect on cell preparation as judged by the investigator.
