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
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.
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.
Inclusion Criteria:
Patient is, in the investigator's opinion, willing and able to comply with the protocol requirements.
Patient has given voluntary written informed consent before performance of any study-related procedure nor part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care.
Patient is ≥ 18 years of age (or the legal age of consent in the jurisdiction in which the study is taking place) at the time of informed consent.
Patient has documented diagnosis of multiple myeloma according to IMWG diagnostic criteria, with at least one of the following high-risk features:
Note: In order to have a representative population with high-risk features, 50% of patients included will have ultra-high risk disease defined as: i) R-ISS 3; ii) Double hit (at least two high-risk cytogenetic abnormalities); iii) One high-risk cytogenetic abnormality + extramedullary disease.
Exclusion Criteria:
Prior or current systemic therapy or SCT for any plasma cell dyscrasia, with the exception of 1 cycle of antimyeloma treatment or the emergency use of a short course (equivalent of dexamethasone 40 mg/day for a maximum 4 days) of corticosteroids before treatment while waiting for results of genetic analysis. A cycle of therapy may include treatment with proteasome inhibitors, immunomodulatory drugs, alkylators and corticosteroids, and/or anti-CD38 monoclonal antibodies (i.e, bortezomib-thalidomide-dexamethasone, D-VTD, bortezomib-lenalidomide-dexamethasone, or bortezomib-cyclophosphamide-dexamethasone, are valid options).
Peripheral neuropathy or neuropathic pain Grade 2 or higher, as defined by the NCI-CTCAE Version 5.
Patient has a diagnosis of primary light chain amyloidosis, monoclonal gammopathy of undetermined significance (MGUS), smoldering multiple myeloma (SMM), plasma cell leukemia or active POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, and skin changes) at the time of screening.
Myelodysplastic syndrome or active malignancies (ie, progressing or requiring treatment change in the last 24 months) other than relapsed/refractory multiple myeloma. The only allowed exceptions are malignancies treated within the last 24 months that are considered completely cured:
Patient has CNS or exhibits clinical signs of meningeal involvement of multiple myeloma. If either is suspected, negative whole brain MRI and lumbar cytology are required.
