Teclistamab-Daratumumab and Talquestamab-Daratumumab in Newly Diagnosed High-risk Multiple Myeloma (GEM-TECTAL)

An Open Label, Multicenter, Phase 2, Pilot Study, Evaluating Early Treatment With Bispecific T-cell Redirectors (Teclistamab and Talquetamab) in the Frontline Therapy of Newly Diagnosed High-risk Multiple Myeloma

The goal of this Phase 2, open-label, multicenter, non-randomized pilot study is to evaluate the efficacy (in terms of MRD negative CR rate after Intensification therapy) and safety of Tec-Dara (Teclistamab+Daratumumab) and Tal-Dara (Talquetamab+Daratumumab) in de novo high-risk multiple myeloma (DNHRMM) patients.

Study Overview

• Status: Recruiting
• Conditions: High-Risk de Novo Multiple Myeloma
• Intervention / Treatment: Drug: Talquetamab; Drug: Teclistamab; Drug: Daratumumab; Drug: Bortezomib; Drug: Lenalidomide

Detailed Description

A total of 30 transplant eligible or elderly fit patients with high risk multiple myeloma will be enrolled

1. Patients will receive a 4-cycle Dara+VRD (daratumumab, bortezomib, lenalidomide, dexamethasone) INDUCTION therapy. Cycles will be of 28 days (4-week cycles) in duration for daratumumab and for VRD.

After the 4-cycle Induction, all patients will receive the 1st INTENSIFICATION treatment which consists of 6 cycles of Tec-Dara. Cycles will be of 28 days (4-week cycles) in duration for daratumumab and for teclistamab.

1st Intsensification, patients will receive a 6-cycle Dara+Teclistamab.

2. At the end of 1st Intensification timepoint treatments depends on MRD status:

2.1) MRD negative patients in CR at the end of Intensification will receive MAINTENANCE therapy with Tec-Dara continuously for 2 years. Cycles will be of 28-days in duration for Tec-Dara. Teclistamab (SC) and daratumumab (SC).

2.2) MRD positive patients or patients who didn't achieve CR despite MRD negativity, will have EARLY RESCUE INTERVENTION (ERI) with Tal-Dara for 6 cycles. MRD and response will be evaluated again after 6 cycles treatment with Tal-Dara. MRD negative patients in CR will receive continuous treatment with Tal-Dara for 2 years.

2.2.1 Early Rescue Intervention with Tal-Dara: Patients who are MRD+ after intensification or who convert from MRD negative into positive or experience a relapse from CR (without fulfilling criteria for disease progression) at any time during Tec-Dara treatment will have ERI with Tal-Dara. Cycles will be of 28 days in duration.

2.2.2. MRD negative patients in CR will receive continuous treatment with Tal-Dara for 2 years. Cycles will be of 28-days of duration for Tal-Dara.

4. SALVAGE therapy: If the patient remains MRD+ or doesn't achieve CR despite MRD negativity after 6 cycles of ERI with Tal-Dara or has disease progression at any time, further treatment will be offered as per the investigation decision outside of the study.
