Comparing Dara-VCD Chemotherapy Plus Stem Cell Transplant to Dara-VCD Chemotherapy Alone for People Who Have Newly Diagnosed AL Amyloidosis

AL Amyloidosis Clinical Trial

Official title: A Phase III, Randomized Study of Daratumumab, Cyclophosphamide, Bortezomib and Dexamethasone (Dara-VCD) Induction Followed by Autologous Stem Cell Transplant or Dara-VCD Consolidation and Daratumumab Maintenance in Patients With Newly Diagnosed AL Amyloidosis

Status Not yet recruiting

Clinical Trial Summary

This phase III trial compares the effect of adding a stem cell transplant with melphalan after completing chemotherapy with daratumumab, cyclophosphamide, bortezomib and dexamethasone (Dara-VCD) versus chemotherapy with Dara-VCD alone for treating patients with newly diagnosed amyloid light chain (AL) amyloidosis. Melphalan is a chemotherapy given prior to a stem cell transplant. Giving chemotherapy before a peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. The stem cells are then returned to the patients to replace the blood forming cells that were destroyed by the chemotherapy. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Chemotherapy drugs, such as cyclophosphamide 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. Dexamethasone is in a class of medications called corticosteroids. It is used to lower the body's immune response to help stop the growth of cancer cells. Giving a stem cell transplant with melphalan after Dara-VCD may kill more cancer cells in patients with newly diagnosed AL amyloidosis.

II. To bank specimens for future use.

TRANSLATIONAL MEDICINE EXPLORATORY OBJECTIVES:

I. To evaluate MRD negativity rates at post-induction, and compare MRD negativity rates at 12 months post-consolidation from bone marrow aspirates via NGF between participants randomized to the ASCT and non-ASCT arms of this study.

II. To investigate the association of achieving MRD negativity at any point (post-induction, post-consolidation, or 12 months post-consolidation) via NGF from bone marrow aspirates with major organ deterioration-progression free survival (MOD-PFS).

III. To investigate the association of achieving sustained MRD negativity (MRD negative at two consecutive measurements -- post-induction, post-consolidation, and 12 months post-consolidation) via NGF from bone marrow aspirates with MOD-PFS.

QUALITY OF LIFE (QOL) PRIMARY OBJECTIVE:

I. To compare patient-reported physical function following consolidation treatment between participants randomized to the ASCT and non-ASCT arms using the Patient Reported Outcomes Measurement Information System (PROMIS)-29+2 Profile version (v) 2.1 physical function sub-scale.

QOL SECONDARY OBJECTIVES:

I. To compare patient-reported fatigue following consolidation treatment between participants randomized to the ASCT and non-ASCT arms using the PROMIS-29 fatigue subscale.

II. To compare longitudinal changes in physical function using the PROMS-29+2 between participants randomized to the ASCT and non-ASCT arms.

QOL EXPLORATORY OBJECTIVES:

I. To assess baseline symptom burden in AL amyloidosis patients prior to induction therapy using the PROMIS-29+2.

II. To compare mean scores of symptom scales using the PROMIS-29+2 following consolidation treatment, and at 6 months and 12 months from step 3 registration between treatment arms.

III. To compare mean scores of functional scales using the PROMIS-29+2, following consolidation treatment, and at 6 months and 12 months from step 3 registration between treatment arms.

IV. To explore whether longitudinal changes in symptoms, functioning, and overall heath related quality of life (HRQoL) as assessed by the PROMIS-29 +2 (version 2.1) differ according to treatment group and, separately, according to baseline cardiac or renal involvement using interaction tests between participants randomized to the ASCT and non-ASCT arms.

V. To compare health utility indices using the PROMIS preference score (PROPr) between patients randomized to the ASCT and non-ASCT arms.

PATIENT REPORTED OUTCOME (PRO)-COMMON TERMINOLOGY CRITERIA FOR ADVERSE EVENTS (CTCAE) PRIMARY OBJECTIVE:

I. To compare patient reported symptoms regarding treatment emergent adverse events of interest using the Patient Reported Outcome CTCAE (PRO-CTCAE) Measurement System between patients randomized to the ASCT and non-ASCT arms of this study.

OUTLINE:
