This study is a randomized, open-label, multicenter Phase III clinical trial involving patients with relapsed/refractory multiple myeloma. The estimated total sample size is 260 cases, who will be randomly assigned in a 1:1 ratio to the test group and the control group. The primary objective of the study is to demonstrate the efficacy of TQB2934 for injection compared to the investigator-selected regimen in subjects with relapsed or refractory multiple myeloma (RRMM) by evaluating progression-free survival (PFS).
Voluntarily join this study, sign the Informed Consent Form (ICF), and demonstrate good compliance.
Aged 18 to 75 years old (as of the date of signing the ICF); gender not limited; Eastern Cooperative Oncology Group Performance Status (ECOG) of 0-2.
Expected survival greater than 3 months.
Patients with relapsed or refractory multiple myeloma.
