Clinical Trial Summary

This is a single-arm, open-label, multicenter, dose-escalation, and dose-expansion phase I/II clinical study to evaluate the safety, tolerability, pharmacokinetics, immunogenicity, and efficacy of LBL-034 in patients with R/R MM.

Description:

A multicenter, open-label, phase I/II clinical study to evaluate the safety, tolerability, pharmacokinetics, and efficacy of LBL-034 in patients with relapsed/refractory multiple myeloma. This trial includes two parts: phase I and phase II study. The dose escalation and dose expansion studies for LBL-034 will be conducted in the phase I study to evaluate safety, tolerability and determine RP2D. The efficacy of LBL-034 in treatment of R/R MM will be evaluated in the phase II study. Phase II study includes 2 arms. This clinical trial will enroll 66-418 patients in Phase I and Phase II studies.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Objective Response Rate (ORR)	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, 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 II study .	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).
Primary	Dose-limiting toxicities(DLT)	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. It was used to evaluate the safety of LBL-034 in Phase I study .	The DLT observation period starts from the first dose to 4 weeks after the full dose first administration (including the step-up dosing period, if any).
Primary	Maximum tolerated dose (MTD)	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 of LBL-034 in Phase I study .	The MTD observation period starts from the first dose to 4 weeks after the full dose first administration (including the step-up dosing period, if any).
Secondary	Cmax	Maximum serum concentration	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)
Secondary	Tmax	After taking a single dose, Time to reach maximum plasma concentration	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)
Secondary	Immunogenicity	The immunogenicity is evaluated by the incidence of anti-drug antibodies (ADA) and neutralizing antibodies (if applicable) in subjects	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)
Secondary	Minimal Residual Disease (MRD)	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.	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)
Secondary	Duration of Response(DOR)	The period from the participants first achieving CR or PR to disease progression.	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)
