Eligibility Criteria
Inclusion Criteria:
- The subject voluntarily participates in the clinical study; Fully understand and be Informed of the study and sign the Informed consent (Informed Consent Form, ICF); Willing to follow and able to complete all test procedures; Informed consent must be obtained before initiating any tests or procedures related to the study that are not part of the standard treatment of the subject's disease;
- Subjects ≥ 18 years of age.
- Eastern Cooperative Oncology Group performance status score of 0, 1, or 2;
- Documented initial diagnosis of MM according to IMWG diagnostic criteria.
- Presence of measurable disease at screening.
- Received a PI and an IMiD (except thalidomide).
- Received at least 3 prior lines of therapy for multiple myeloma, undergone at least 1 complete cycle of treatment for each line, unless progressive disease (PD) was documented by IMWG criteria as the best response to the regimen. Also, subjects refractory or intolerant to any PI and any IMiD in their previous treatment afterwards are eligible.
- Expected survival ≥ 3 months.
- Clinical laboratory values meet screening visit criteria
- Fertile women must be negative using a highly sensitive serum pregnancy test (β human chorionic gonadotropin [β -HCG]) at screening time and before initial treatment with cyclophosphamide and fludarabine;
Exclusion Criteria:
- No response to prior BCMA-targeted CAR-T therapy (except in subjects who relapsed after CR to prior CAR-T treatment);
- Prior treatment with any antibody targeting BCMA;
- Known active, or prior history of central nervous system (CNS) involvement, or clinical signs of membrane/spinal membrane involvement of multiple myeloma;
- Serious underlying medical conditions
- Positive of any hepatitis B surface antigen (HBsAg), hepatitis B virus deoxyribonucleic acid (HBV DNA), hepatitis C antibody (HCV-Ab), hepatitis C virus ribonucleic acid (HCV RNA), human immunodeficiency virus antibody (HIV-Ab) at the time of screening;
- Male subjects who have a birth plan during the study period or within 1 year after the study treatment
- Female subjects who are pregnant, breast-feeding, or plan to become pregnant during the study period or within 1 year after the study treatment

Outcomes
Primary Outcome Measures
Incidence, severity, and type of treatment-emergent adverse events (TEAEs)
An adverse event refers to any untoward medical occurrence in a clinical investigation subject administered a pharmaceutical product (investigational or non-investigational), which does not necessarily have a causal relationship with the treatment
Dose-limiting toxicity (DLT) rate
Dose-limiting toxicity (DLT) refers to a drug-related toxicity during treatment with the drug, the severity of which is clinically unacceptable, limiting the further escalation of drug dose
Recommended Phase 2 dose (RP2D) finding
RP2D established through ATD+BOIN design
CAR positive NK cells in peripheral blood and bone marrow
CAR positive NK cells in peripheral blood and bone marrow after LUCAR-B68 infusion
CAR transgene levels in peripheral blood
CAR transgene levels in peripheral blood after LUCAR-B68 infusion
Secondary Outcome Measures
Overall response rate (ORR)
The ORR is defined as the percentage of participants who achieve partial response (PR) or better according to international myeloma working group (IMWG) criteria
Duration of Response (DOR)
Duration of response (DOR) will be calculated among responders (with a PR or better response) from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in the IMWG criteria or death due to any cause, whichever occurs first
Time to Response (TTR)
Time to response (TTR) is defined as the time between date of the initial infusion of LCAR-B38M CAR-T cells and the first efficacy evaluation that the participant has met all criteria for PR or better
Progress Free Survival (PFS)
Progression Free Survival (PFS) is defined as the time from the date of first infusion of the LUCAR-B68 to the first documented disease progression (according to IMWG criteria) or death (due to any cause), whichever occurs first
Overall Survival (OS)
Overall Survival (OS) is defined as the time from the date of first infusion of LUCAR-B68 to death of the subject
Incidence of anti- LUCAR-B68 antibody
Venous blood samples will be collected to measure LUCAR-B68 positive cell concentrations and the transgenic level of LUCAR-B68, at the time points when anti- LUCAR-B68 antibody serum samples are evaluated
