What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 70 participants in total. It began in 2025-12-26 with a primary completion date of 2029-02.

Brief 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.
