Group Intervention Description OriCAR-017 ( GPCRC5D-directed chimeric antigen receptor modified T cells ) OriCAR-017 Phase I (Dose-Escalation) The subjects enrolled will be sequentially assigned to the corresponding dose level to determin the RP2D. The dose-escalation part of the study will adopt the the standard 3+3 design, wherein 3 dose levels are planned to be evaluated. Phase I (Dose-Expansion) After determining the RP2D, one of the dose levels will be selected for further evaluation during the dose-expansion part. Up to 10 to 15 additional subjects who are diagnosed with relapsed/refractory MM will be enrolled to further explore the anti-tumor activity of Ori-CAR-017. Phase II The Phase II part of the study will be initiated at the RP2D of OriCAR-017 which will be selected based on the clinical data obtained during the Phase I part of the study.
- Primary Outcome Measures
Name Time Method Maximum tolerated dose of OriCAR-017-P1 Up to 28 days The MTD is defined as the highest dose with an observed incidence of DLT in no more than one out of six patients treated at a particular dose level.
Dose-limiting toxicity (DLT) Up to 28 days tolerability
- Secondary Outcome Measures
Name Time Method Pharmacokinetics (the number of cell copies and cell persistence duration in peripheral blood) From date of randomization until the date of first documented progression or date of death from any cause or withdraw, whichever came first, assessed up to 2 years CAR-GPRC5D DNA in peripheral blood detected by q-PCR at each visit after infusion
Long term survival follow up From date of randomization until the date of first documented date of death from any cause, assessed up to 15 years The period from randomization until the date of death
Objective Response Rate From date of randomization until the date of first documented progression or date of death from any cause or withdraw, whichever came first, assessed up to 2 Years Objective response is defined as the participants with a partial response (PR) or better by the RECIST1.1 criteria.
Antitumor efficacy-Duration of response (DOR) From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years The period from the first evaluation of sCR or CR or VGPR or PR or MR to the first evaluation of PD or death of any cause
Antitumor efficacy-Progression-free survival (PFS) From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 2 years The period from the day when the subject receives the infusion of cells to the first recorded tumor progression
