Daratumumab, Ixazomib, and Dexamethasone with or without Bortezomib in Treating Patients with Newly Diagnosed Multiple Myeloma

Trial Status: Active

This phase II trial studies how well daratumumab, ixazomib, and dexamethasone with or without bortezomib work in treating patients with newly diagnosed multiple myeloma. Immunotherapy with monoclonal antibodies, such as daratumumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as ixazomib, dexamethasone, and bortezomib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving daratumumab, ixazomib, and dexamethasone with or without bortezomib may work better in treating patients with multiple myeloma.

Inclusion Criteria

  • Patients must meet the following criteria on screening examination to be eligible to participate in the study. All laboratory assessments should be performed within 21 days of initiation of protocol therapy unless otherwise specified. Subject is, in the investigator’s opinion, willing and able to comply with the protocol requirements
  • Subject has given voluntary signed written informed consent before performance of any study-related procedure that is not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to their future medical care

In addition, the patient must meet one of the criteria in d1 or d2: * Evidence of end organ damage that can be attributed to the underlying plasma cell proliferative disorder, specifically (one or more of the following): ** Hypercalcemia: serum calcium > 0.25 mmol/L (> 1 mg/dL) higher than the upper limit of normal (ULN) or > 2.75 mmol/L (> 11 mg/dL) ** Renal insufficiency: Creatinine clearance (CrCl) < 40 mL/min (measured or estimated by validated equations) or serum creatinine > 177 umol/L (> 2 mg/dL) ** Anemia: hemoglobin value of > 20 g/L below the lower limit of normal, or a hemoglobin value < 100 g/L ** Bone lesions: 1 or more osteolytic lesions on skeletal radiography, computed tomography (CT), or magnetic resonance imaging (MRI) *** Clonality should be established by showing kappa/lambda-light-chain restriction on flow cytometry, immunohistochemistry, or immunofluorescence. Bone marrow plasma cell percentage should preferably be estimated from a core biopsy specimen; in case of a disparity between the aspirate and core biopsy, the highest value should be used * Any one or more of the following: ** Clonal bone marrow plasma cell percentage >= 60% *** Clonality should be established by showing kappa/lambda-light-chain restriction on flow cytometry, immunohistochemistry, or immunofluorescence. Bone marrow plasma cell percentage should preferably be estimated from a core biopsy specimen; in case of a disparity between the aspirate and core biopsy, the highest value should be used ** Involved:uninvolved serum free light chain (FLC) ratio > 100 *** These values are based on the serum Freelite assay (The Binding Site Group, Birmingham, UK).

  • Measurable disease as defined by any of the following: * Serum M-protein level >= 1.0 g/dL or urine M-protein level >= 200 mg/24 hours. Note: All attempts should be made to determine eligibility of the subject based on the central laboratory results of screening blood and urine M-protein measurements. In exceptional circumstances, the local laboratory results for blood and urine M-protein measurements may be used to determine eligibility, but only if the results are clearly (eg, 25% or more) above the thresholds for measurability; or * IgA, IgD, IgE, or IgM multiple myeloma: serum M-protein level >= 0.5 g/dL or urine M-protein level >= 200 mg/24 hours; or * Light chain multiple myeloma without measurable disease in the urine: serum Ig FLC >= 10 mg/dL and abnormal serum Ig kappa/lambda FLC ratio

PRIMARY OBJECTIVE:

I. To determine the >= very good partial response (VGPR) rate after 8 cycles in subjects treated with daratumumab, ixazomib and dexamethasone (DId) versus (vs) daratumumab, bortezomib and dexamethasone (DVd) followed by DId among newly diagnosed myeloma patients (NDMM).

SECONDARY OBJECTIVES:

I. To estimate the proportion of subjects with successful stem cell mobilization after receiving 3 cycles of treatment in both arms (DId x 8 vs DVd x 3 then DId x 5).

II. To establish safety among patients receiving the combination of DId and DVd then DId.

III. To obtain anti-tumor activity (best response rates: overall response rate [ORR], VGPR, complete response [CR], stringent complete response [sCR] and minimal residual of disease [MRD] negativity) in patients treated with these combinations.

IV. Progression free survival (PFS), progression free survival 2 (PFS2), duration of response (DOR), time to progression (TTP), determine the time to next therapy (TTNT).

V. Overall survival (OS).

VI. Engraftment parameters among the autologous stem cell transplant (ASCT) group.

VII. Determine whether tumor response and PFS may change in subgroups with different prognosis according to current prognostic factors.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I:

INDUCTION: Patients receive dexamethasone intravenously (IV) and orally (PO) on days 1, 8, 15, and 22, daratumumab IV on days 1, 8, 15, and 22 of cycles 1-2 and on days 1 and 15 of cycles 3-8, and ixazomib PO on days 1, 8, and 15. Treatment repeats every 28 days for 8 cycles in the absence of disease progression or unacceptable toxicity. Eligible patients then undergo stem cell transplant per standard of care. Patients who have at least stable disease after induction and patients who have undergone transplant continue to Maintenance.

MAINTENANCE: Patients receive dexamethasone IV and PO on days 1, 8, 15, and 22, daratumumab IV on day 1, and ixazomib PO on days 1, 8, and 15. Cycles repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

ARM II:

INDUCTION CYCLES 1-3: Patients receive dexamethasone IV and PO on days 1, 8, and 15, daratumumab IV on days 1, 8, and 15, and bortezomib subcutaneously (SC) on days 1, 4, 8, and 11. Treatment repeats every 21 days for 3 cycles in the absence of disease progression or unacceptable toxicity.

INDUCTION CYCLES 4-8: Patients receive dexamethasone IV and PO on days 1, 8, 15, and 22, daratumumab IV on days 1 and 15, and ixazomib PO on days 1, 8, and 15. Treatment repeats every 28 days for 5 cycles in the absence of disease progression or unacceptable toxicity. Eligible patients then undergo stem cell transplant per standard of care. Patients who have at least stable disease after induction and patients who have undergone transplant continue to Maintenance.

MAINTENANCE: Patients receive dexamethasone IV on day 1, daratumumab IV on day 1, and ixazomib PO on days 1, 8, and 15. Cycles repeat every 28 days for up to 24 months in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months.
