Details and patient eligibility

About

The purpose of this study is to characterize cardiac safety of Daratumumab, Cyclophosphamide, Bortezomib, and Dexamethasone (D-VCd) treatment regimens (Arm A: daratumumab + immediate VCd treatment and Arm B: daratumumab + deferred VCd) in newly diagnosed systemic amyloid light chain (AL) amyloidosis with cardiac involvement and to identify potential mitigation strategies for cardiac toxicity (cohort 1); to characterize the pharmacokinetics of subcutaneous (SC) daratumumab, among racial and ethnic minorities, including Black or African American, with newly diagnosed AL amyloidosis treated with D-VCd (cohort 2).

Inclusion criteria

  • Cohort 1: Cardiac involvement (amyloid light chain [AL] amyloidosis Mayo Cardiac Stage II and Stage IIIa) with or without other organ(s) involved; Cohort 2: One or more organs impacted by systemic AL amyloidosis according to consensus guidelines
  • Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0, 1 or 2
  • A female participant of childbearing potential must have a negative serum or urine test at screening and within 72 hours of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study
  • A male participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum of 6 months after receiving the last dose of cyclophosphamide or 100 days after discontinuation of daratumumab, whichever is longer
  • Cohort 2 only: self-identified racial and ethnic minorities, including Black or African American
  • Measurable disease at screening defined by one of the following:

Difference between iFLC and uninvolved FLC (dFLC) >= 40mg/L per central laboratory Serum involved free light chain (iFLC) >= 40 mg/L with an abnormal kappa:lambda ratio Serum M-protein >= 0.5 g/dL

Exclusion criteria

  • Prior therapy for systemic AL amyloidosis or multiple myeloma including medications that target cluster of differentiation 38 (CD38), with the exception of 160 milligrams(mg) dexamethasone or equivalent corticosteroid maximum exposure prior to randomization/enrollment

  • Previous or current diagnosis of symptomatic multiple myeloma, including the presence of lytic bone disease, plasmacytomas, >=60% plasma cells in the bone marrow, or hypercalcemia related to myeloma.

  • Participant received any of the following therapies:

    1. treatment with an investigational drug or used an invasive investigational medical device within 14 days or at least 5 half-lives, whichever is less;
    2. vaccinated with an investigational vaccine (except for COVID-19) live, attenuated or replicating viral vector vaccines less than (<) 4 weeks prior to randomization/enrollment. Participants who are taking strong Cytochrome P450 3A4(CYP3A4) inducers must discontinue their use at least 5 half-lives prior to the first dose of bortezomib
  • Stem cell transplantation -Planned stem cell transplant during the first 9 cycles of protocol therapy are excluded. Stem cell collection during the first 9 cycles of protocol therapy is permitted

  • Grade 2 sensory or Grade 1 painful peripheral neuropathy

150 participants in 3 patient groups

Cohort1 (Arm A): Daratumumab + Immediate Cyclophosphamide, Bortezomib and Dexamethasone (VCd)
Experimental group
Description:
Participants with newly diagnosed systemic amyloid light chain (AL) amyloidosis with Mayo Cardiac Stage II and IIIa cardiac involvement will receive daratumumab 1800 milligrams (mg) subcutaneously (SC) starting on Day 1 once weekly (q1w) up to Day 22 for cycles 1-2, on Days 1 and 15 for cycles 3-6, and on Day 1 for cycles 7-24 of a 28-day cycle. Participants will also receive VCd (cyclophosphamide 300 milligrams per meter square \[mg/m\^2\] either orally or intravenously \[IV\], bortezomib 1.3 mg/m\^2 SC or IV, dexamethasone 40 mg weekly either orally or IV) weekly starting at Cycle 1 Day 1 up to Day 22 in every 28-day cycle for a maximum of 6 cycles (Cycle 6 Day 22).
Treatment:
Drug: Bortezomib
Drug: Daratumumab
Drug: Dexamethasone
Drug: Cyclophosphamide
Cohort1 (Arm B): Daratumumab + Deferred VCd
Experimental group
Description:
Participants with newly diagnosed systemic AL amyloidosis with Mayo Cardiac Stage II and IIIa cardiac involvement will receive SC daratumumab 1800mg on Day 1 once weekly (q1w) up to Day 22 for cycles 1-2, on Days 1 and 15 for cycles 3-6, and on Day 1 for cycles 7-24 of a 28-day cycle. Participants will also receive VCd (Cyclophosphamide 300 mg/m\^2 either orally or IV, Bortezomib 1.3 mg/m\^2 SC or IV, Dexamethasone 40 mg weekly either orally or IV) starting at Cycle 4 Day 1, weekly (Days 1, 8, 15, 22) in every 28-day cycle for a maximum of 6 cycles (Cycle 9 Day 22).

Participants will also receive VCd (cyclophosphamide 300 milligrams per meter square \[mg/m\^2\] either orally or intravenously \[IV\], bortezomib 1.3 mg/m\^2 SC or IV, dexamethasone 40 mg weekly either orally or IV) weekly starting at Cycle 1 Day 1 up to Day 22 in every 28-day cycle for a maximum of 6 cycles (Cycle 6 Day 22).
