Isatuximab in combination with bortezomib and lenalidomide with minimal dexamethasone in transplant-ineligible multiple myeloma

A Phase 2, single arm, open label, multicenter study to assess minimal residual disease after isatuximab in combination with bortezomib and lenalidomide with minimal dexamethasone in patients with newly diagnosed multiple myeloma ineligible for autologous transplant. - The REST (Replacing Steroids in the transplant ineligible) study.

Inclusion criteria

Inclusion criteria: 1. Participant must be >18 years of age at the time of signing the informed consent. 2. Newly diagnosed multiple myeloma (International Myeloma Working Group (IMWG) criteria) in-eligible for high-dose therapy and ASCT. 3. Measurable disease as defined by the IMWG: a. Serum monoclonal paraprotein (M-protein) level > 10 g/L or urine M-protein level >200 mg/24 hours; or b. Light chain multiple myeloma without measurable disease in the serum or the urine: Serum immunoglobulin FLC > 100 mg/L and abnormal serum immunoglobulin kappa lambda FLC ratio. 4. Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2. ECOG 3 can be enrolled if caused by myeloma. 5. Clinical laboratory values meeting the following criteria during the Screening Phase a. Adequate bone marrow function: - Hemoglobin >7,5 g/dL (transfusion is permitted, recombinant human EPO use is permitted, however transfusion is not permitted within 3 days before screening). - Absolute neutrophil count > 1.0 x 109/L (G-CSF use is permitted). - Platelet count >50 x 109/L. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 5 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 45

Exclusion criteria

Exclusion criteria: 1. Prior or current systemic therapy for multiple myeloma with the exception of emergency use of a short course (equivalent of dexamethasone 40 mg/day for a maximum 4 days) of corticosteroids before treatment. 2. Radiation therapy for treatment of plasmacytoma within 14 days of treatment (local radiation for pain control or to prevent fracture is allowed within 14 days of treatment). 3. Active hepatitis B or C virus infection or known human immunodeficiency virus (HIV) positivity. 4. Any other serious medical or psychiatric illness that could, in the investigator’s opinion, potentially interfere with the completion of treatment according to this protocol. 5. No active malignancy with a lower life expectancy than myeloma 6. Female patients who are lactating or have a positive serum pregnancy test during the screening period. 7. Known allergy to any of the study medications, their analogues, or excipients in the various formulations of any agent.

Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective is to determine how many patients achieve minimal residual disease (MRD) negativity during and/or after 2 cycles of IVRd, followed by 6 cycles of IVR and 10 cycles of IR.;Secondary Objective: 1. To assess the overall response rate (ORR) after 2 cycles of IVRd followed by 6 cycles of IVR and 10 cycles of IR. 2. To determine the progression free survival (PFS) rate after 2 cycles of IVRd followed by 6 cycles of IVR, 10 cycles of IR and continuous R. 3. To determine the overall survival (OS) rate after 2 cycles of IVRd followed by 6 cycles of IVR, 10 cycles of IR and continuous R. 4. To evaluate health related quality of life (HRQL) and symptoms of steroid toxicity during IVRd (cycle 1 and 2 with dexamethasone) compared to IVR (cycle 4 and 3 without dexamethasone) treatment. ;Primary end point(s): The number of patients who achieve MRD negativity measured by NGF Euroflow during and/or after 18 cycles of study treatment.;Timepoint(s) of evaluation of this end point: Approximately 36 months after FPI

Secondary

MeasureTime frame
Secondary end point(s): 1.The proportion of patients who achieve partial response (PR) or better following 18 cycles of study treatment. 2. The PFS rate of patients receiving 2 cycles of IVRd followed by 6 cycles of IVR, 10 cycles of IR and continuous R. 3. The OS rate of patients receiving 2 cycles of IVRd followed by 6 cycles of IVR, 10 cycles of IR and continuous R. 4. The change in HRQL trajectories and steroid toxicity (day 22 – day 1) during IVRd (cycle 1 and 2) compared to IVR (cycle 4 and 5). ;Timepoint(s) of evaluation of this end point: See E.5.2
