Overview
This is a prospective, single-arm, open-label dose-escalation clinical study to evaluate LVIVO-TaVec200 in the treatment of relapsed/refractory multiple myeloma.
Description
This is a prospective, single-arm, open-label dose-escalation and dose-expansion study, designed to evaluate the safety, tolerability, anti-tumor efficacy profile, and pharmacokinetic characteristics of the LVIVO-TaVec200 in subjects with relapsed/refractory multiple myeloma who have failed at least 3 lines of prior standard therapies. The subject who meet the defined eligibility criteria will be enrolled with a core study period of approximately 2 years, including the screening, bridging therapy(if needed), treatment, and follow-up.
Eligibility
Inclusion Criteria:
- Subjects voluntarily participate in clinical studies; Fully informed of this study and signed informed consent; Informed consent form must be obtained prior to initiation of any study-related tests or procedures that are not part of the standard treatment for the subject's disease; Good compliance and cooperation with follow-up.
- Age ≥ 18 years.
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
- Has measurable lesions
- Relapsed and/or refractory multiple myeloma
- Life expectancy≥ 3 months
- Clinical laboratory values meet screening visit criteria
- Adequate organ function.
Exclusion Criteria:
- Prior antitumor therapy with insufficient washout period ;
- Prior treatment targeting GPRC5D;
- Patients who are positive for hepatitis B surface antigen (HBsAg), hepatitis B virus deoxyribonucleic acid (HBV DNA), hepatitis C antibody (HCV-Ab), hepatitis C virus ribonucleic acid (HCV RNA), and human immunodeficiency virus antibody (HIV-Ab).
- Known life-threatening allergic reaction, hypersensitivity reaction, or intolerance to study drug excipients and related excipients, including but not limited to DMSO; or those with a history of severe allergic reactions in the past (such as hypersensitivity reactions, or those with severe immune-related reactions such as the need for glucocorticoids to prevent anaphylaxis as assessed by the investigator).
- Any condition deemed by the investigator as rendering the subject unsuitable for participation in this study.
