Intervention name:
BCMA/GPRC5D double CAR-T
Description:
BCMA/GPRC5D double CAR-T is a new type CAR-T cells therapy for patients with Multiple
Myeloma.
Arm group label:
BCMA/GPRC5D double CAR-T
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 occurrence and a dosage of 3×106/kg±20%~1×107/kg ±20%
CAR positive T cells.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
1. 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;
2. Aged 18-75 years, male or female;
3. According to IMWG diagnostic criteria, diagnosed with multiple myeloma;
4. 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.
5. 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;
6. 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);
7. ECOG performance status score 0 to 2 and expected survival greater than 3 months;
8. 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 Criteria:
1. 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;
2. 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);
3. Any hematopoietic stem cell transplantation within 2 months before screening;
4. History of central nervous system diseases;
5. known active central nervous system (CNS) involvement or clinical signs of meningeal
involvement in multiple myeloma;
6. Waldenström macroglobulinemia, POEMS syndrome (polyneuropathy, organomegaly,
endocrinopathy, monoclonal proteinopathy, and skin changes) or primary AL
amyloidosis at screening;
7. 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;
8. 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

screening or coronary artery bypass grafting (CABG), a history of unexplained

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);
10. unstable systemic diseases judged by the investigator: including but not limited to
severe liver, kidney or metabolic diseases requiring drug treatment;
