Summary

This study is a clinical trial aimed at the marketing of TQB2934 for injection. The project plans to enroll 70 subjects, including 13-21 subjects in Phase Ib, to evaluate the safety and preliminary efficacy, pharmacokinetic (PK) characteristics, immunogenicity, and pharmacodynamic (PD) of TQB2934 for injection in subjects with systemic light chain amyloidosis, and to determine the recommended Phase II dose (RP2D). The Phase II plan involves enrolling 49 subjects, aiming to demonstrate that in adult subjects with relapsed/refractory systemic light chain amyloidosis who have previously received treatment with daratumumab and bortezomib, TQB2934 for injection significantly improves the hematological complete response (CR) rate compared to historical controls. The primary endpoint is the optimal hematological CR rate.

Conditions

  • Systemic Light Chain Amyloidosis

Interventions

DRUG

TQB2934 injection

TQB2934 for injection is a bispecific antibody targeting B-cell maturation antigen (BCMA) and Cluster of Differentiation 3 (CD3). One end binds to the CD3 receptor on the surface of T cells, while the other end binds to BCMA, recruiting T cells to BCMA-positive cells. This can activate T cells, which then release granzyme, perforin, and other enzymes to kill BCMA-positive malignant plasma cells, thereby reducing the level of monoclonal immunoglobulin light chains in the body and delaying further organ damage.
