Study of SubQ Dara With Dose-Attenuated Bortezomib, Lenalidomide, Dexamethasone in Elderly NDMM

A Phase 2 Study of Subcutaneous Daratumumab in Combination With Dose-Attenuated Bortezomib, Lenalidomide, and Dexamethasone in Elderly Newly Diagnosed Multiple Myeloma Patients

This is a single center, open-label, phase 2 study in elderly (age ≥ 70) subjects with newly diagnosed multiple myeloma who are transplant ineligible. Subjects will receive subcutaneous daratumumab, dose-attenuated bortezomib, revlimid, and dexamethasone until confirmed disease progression, discontinuation of study treatment due to unacceptable drug toxicity, or other reasons. Throughout the study, subjects will be monitored closely for adverse events, laboratory abnormalities, and clinical response.

Study Overview

• Status: Recruiting
• Conditions: Newly Diagnosed Multiple Myeloma
• Intervention / Treatment: Drug: Daratumumab; Drug: Bortezomib; Drug: Lenalidomide; Drug: Dexamethasone; Drug: Ixazomib

Detailed Description

This is a single center, open-label, phase 2 study in elderly (age ≥ 70) subjects with newly diagnosed multiple myeloma who are transplant ineligible. The main study consists of the following phases: a 28-day screening phase; followed by initial therapy with 12 cycles of daratumumab in combination with dose-attenuated VRd; and a maintenance phase that starts after Cycle 12 of therapy. Cycles are 28 days in length. Treatment can continue until disease progression or unacceptable toxicity. After 12 cycles of initial therapy, maintenance therapy will begin with 28 day cycles of daratumumab with either lenalidomide or ixazomib and the choice of maintenance therapy will be based on cytogenetic risk status at diagnosis. All subjects will continue maintenance treatment until disease progression, except maintenance daratumumab will be discontinued after 2 years if subjects remain on maintenance treatment at that time. All subjects will be followed in the longterm follow-up for at least 1 year after last dose of study treatment and will continue until death, withdrawal of consent for study participation, or the end of study definition is met. The end of study is defined as when all subjects have completed at least 1 year of long-term follow up and until death, withdrawal of consent for study participation, or 5 years after first patient begins daratumumab therapy, whichever occurs first.

    • Any one or more of the following biomarkers of malignancy:

      • Clonal bone marrow plasma cell percentage** (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 ≥60% or
      • Serum free light chain (FLC) ratio greater than or equal to 100 provided involved FLC level is 100 mg/L or higher, or

Arms and Interventions

Participant Group / Arm

Intervention / Treatment

Experimental: Daratumumab with dose-attenuated VRd; SubQ Daratumumab with Dose-Attenuated VRd

Drug: Daratumumab; Daratumumab 1800 mg will be delivered by subcutaneous injection given through a syringe and needle by a manual push over approximately 3 to 5 minutes. Doses will be administered at alternating locations on the abdomen. Daratumumab will be administered weekly during treatment in Cycles 1 to 2, every 2 weeks during cycles 3-6, and every 4 weeks thereafter.; Drug: Bortezomib; Subjects will receive 1.3 mg/m2 bortezomib as a subcutaneous infusion on Days 1, 8, and 15 during the 28-day cycles.; Drug: Lenalidomide; In Cycles 1 through 12, lenalidomide will be self-administered at a dose of 15 mg orally each day on Days 1 through 21 of each 28-day cycle. For subjects with CrCl 30-60mL/min, lenalidomide will be reduced to 10mg daily, and for subjects with CrCl 15-30 mL/min, lenalidomide will be reduced to 5mg daily. In maintenance phase: lenalidomide will be administered at one dose level below Cycles 1-12 dosing ie 10 mg orally daily. In maintenance, for subjects with CrCl 30-60 mL/min, lenalidomide will be reduced to 5 mg daily during maintenance treatment, and for subjects with CrCl 15-30 mL/min, lenalidomide will be reduced to 5 mg every other day during maintenance treatment.; Drug: Dexamethasone; Dexamethasone will be self-administered orally at a total dose of 20 mg weekly during cycles. However, the dexamethasone 20 mg oral or IV (only if oral is not available) dose administered as a preinfusion medication on daratumumab infusion days replaces the oral dexamethasone dose for that day. Dexamethasone will be administered until the subject experiences disease progression or unacceptable toxicity. In the maintenance phase, dexamethasone/steroid premedications may be tapered or discontinued in the absence of daratumumab related infusion reactions/based on patient tolerance. In the event of persistent daratumumab related infusion reactions, the least amount of steroid premedications needed to prevent the same may be used.; Drug: Ixazomib; During maintenance treatment, if choice of maintenance therapy includes ixazomib, ixazomib will be administered at 3 mg orally daily on Days 1,8, and 15 of each cycle. For subjects with CrCl 15-30 mL/min, ixazomib will be reduced to 2.3 mg once per week during maintenance treatment.
