A Phase II Study to Evaluate the Efficacy and Safety of Teclistamab in Combination With Daratumumab (Tec-Dara) in Newly Diagnosed Multiple Myeloma With Concurrent Light Chain Amyloidosis (MM+AL)

The goal of this clinical trial is to learn if teclistamab in combination with daratumumab (Tec-Dara) works to treat newly diagnosed multiple myeloma with concurrent light chain amyloidosis (MM+AL). It will also learn about the safety of this combination. The main questions it aims to answer are:

Does Tec-Dara improve the 1-year progression-free survival rate compared to historical data (50% to 75%) in MM+AL patients? What are the rates of hematologic response (ORR, VGPR, CR, MRD negativity) and organ response in MM+AL patients treated with Tec-Dara? What medical problems do participants have when taking Tec-Dara?

Participants will:

Receive teclistamab subcutaneous injection with step-up dosing (0.06, 0.3, 1.5 mg/kg), followed by 1.5 mg/kg weekly in Cycle 1, 3.0 mg/kg every 2 weeks in Cycles 2-3, and 3.0 mg/kg every 4 weeks in Cycles 4-24 Receive daratumumab subcutaneous injection 1800 mg weekly in Cycles 1-2, every 2 weeks in Cycles 3-6, and every 4 weeks in Cycles 7-24 Continue treatment until disease progression, unacceptable toxicity, or a maximum of 24 cycles Undergo disease assessments every 28 days (±7 days) including laboratory tests for hematologic and organ response evaluation Provide bone marrow samples for MRD and RNA sequencing analysis

Intervento / Trattamento
Sperimentale: Treatment Group

Teclistamab (subcutaneous injection) with step-up dosing: 0.06 mg/kg, 0.3 mg/kg, and 1.5 mg/kg on Days 1, 3, and 5 of Cycle 1, followed by 1.5 mg/kg weekly in Cycle 1, 3.0 mg/kg every 2 weeks in Cycles 2-3, and 3.0 mg/kg every 4 weeks in Cycles 4-24.

Daratumumab (subcutaneous injection) 1800 mg weekly in Cycles 1-2, every 2 weeks in Cycles 3-6, and every 4 weeks in Cycles 7-24.

Treatment continues until disease progression, unacceptable toxicity, or a maximum of 24 cycles (approximately 2 years).
Droga: Teclistamab

Teclistamab: A humanized IgG4-PAA bispecific antibody targeting BCMA and CD3. It bridges malignant plasma cells and CD3+ T cells, leading to T cell activation and perforin/granzyme-mediated lysis of BCMA+ tumor cells.

Daratumumab: A humanized IgG1κ monoclonal antibody targeting CD38, which induces tumor cell lysis through complement-dependent cytotoxicity, antibody-dependent cell-mediated cytotoxicity, and antibody-dependent cellular phagocytosis. It also enhances T cell-mediated anti-myeloma immunity by increasing cytotoxic T helper cells and depleting CD38+ immunoregulatory cells, thereby potentiating teclistamab's activity.

Misura del risultato
Misura Descrizione
Lasso di tempo
Differential gene expression in bone marrow by RNA sequencing between baseline and disease progression in MM-AL patients.
