Objective Response Rate (ORR) Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy). ORR \\\[including the rates of Strin-gent complete response(sCR),complete response (CR) ,Very good partial response(VGPR),and partial response (PR)\\\], evaluated based on the 2016 IMWG criteria(Cohorts 1, 2, and 3) and 2013 IMWG criteria(Cohort 4), refers to the percentage of study subjects who achieve a complete response or partial response. It was used to evaluate the efficacy of LBL-034 in Phase IIa study . 2. Dose-limiting toxicities（DLT） Timeframe: The DLT observation period starts from the first dose until 4 weeks after the full dose first administration (including the step-up dosing period, if any). DLT describes side effects of a drug or other treatment that are serious enough to prevent an increase in dose or level of that treatment.DLT is defined as toxicity (possible adverse events related to LBL-034) during the DLT observation period . It was used to evaluate the safety of LBL-034 in Phase I study . 3. Maximum tolerated dose (MTD) Timeframe: The MTD observation period starts from the first dose until 4 weeks after the full dose first administration (including the step-up dosing period, if any). MTD is defined as the hightest dose level at which no more than 1 out of 6 subjects experiences a DLT during the first cycles. It was used to evaluate the tolerability in Phase I. ### Secondary outcomes 1. Cmax Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) Maximum drug concentration in plasma after administration. 2. Tmax Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) After administration,Time to reach maximum drug concentration in plasma. 3. Immunogenicity Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) The immunogenicity is evaluated by the incidence of anti-drug antibodies (ADA) and neutralizing antibodies (if applicable) in subjects.Immunogenicity refers to the performance that can elicit an immune response. 4. Minimal Residual Disease (MRD) Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) MRD-negative rate: Refers to the percentage of subjects who achieve MRD negativity at any time point after the initial dose and before disease progression or the initiation of a new anti-tumor therapy. 5. Duration of Response(DOR） Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) DOR is defined as the duration from earliest date of disease response (CR、PR 、iCR or iPR) until earliest date of disease progression or death from any cause(if occurring sooner than progression). 6. sBCMA Timeframe: From all subjects signed the informed consent form up to the completion of the follow-up period of drug withdrawal (30 days after drug withdrawal or before the start of new anti-tumor therapy) serum B-cell maturation antigen(Detect the change of sBCMA in serum) Sources for outcomes Source: [clinicaltrials.gov](https://clinicaltrials.gov/study/NCT06049290) ## Eligibility **Sex** All **Age groups** Adults, Older adults **Minimum age** 18 Years **Healthy volunteers** No ### Inclusion criteria 1.

Fertile men and women of childbearing age are willing to take effective contraceptive measures (including abstinence, intrauterine devices, hormonal contraception, and correct use of condoms) from the signing of the informed consent form to 6 months after the last dose of the investigational drug; women of childbearing age include premenopausal women and women who had menopause less than two years ago. Blood pregnancy test results must be negative for women of childbearing age within 7 days prior to the initial dose of the investigational drug. ### Exclusion criteria 1. Subjects who underwent major organ surgery (excluding needle biopsy) or significant trauma within 4 weeks prior to the initial use of the investigational drug,or require elective surgery during the trial period; 2. Use of immunomodulatory drugs within 14 days prior to the initial use of the investigational drug, including but not limited to thymosin, interleukin-2, and interferon； 3. Systemic use of corticosteroids or other immunosuppressants within 14 days prior to the initial use of the investigational drug;The following conditions are excluded: Treatment with topical, ocular, intra-articular, intranasal, and inhaled corticosteroids; short-term use of glucocorticoids for preventive therapy (e.g., to prevent contrast allergy); 4. Patients with active hepatitis B or C； 5. Subjects with an active infection that currently requires intravenous anti infective therapy; 6. The patient has a Medical history of immunodeficiency, including HIV antibody positive; 7. Women during pregnancy or lactation; 8. The investigator believes that the subject has other conditions that may affect compliance or are not suitable for participating in this study.
