This is a phase II interventional study evaluating the use of minimal residual disease by next generation sequencing to defer autologous hematopoietic stem cell transplantation (AHCT) in patients with newly diagnosed multiple myeloma (cohort A) and amyloidosis (cohort B).
While AHCT is an important treatment strategy for patients with plasma cell disorders, from a safety standpoint, AHCT is associated with both acute toxicities that reduce quality of life and long-term toxicities that may limit life expectancy for some patients. Additionally its benefit in patients without evidence of minimal residual disease (MRD) is unknown. We propose to examine MRD response as a strategy to defer AHCT in a systematic manner.

Patients in Cohort A with newly diagnosed multiple myeloma will receive six cycles of combination quadruplet therapy (DaraVRD). Six 28-day induction cycles of oral lenalidomide (25 mg daily on days 1-21), subcutaneous bortezomib (1.3 mg/m2 on days 1, 8, 15, 22), subcutaneous daratumumab (1800 mg on days 1, 8, 15, 22 of cycles 1-2 and days 1, 15 for cycles 3-6), and oral dexamethasone (40 mg on days 1, 8, 15, and 22). Patients in Cohort B with newly diagnosed amyloidosis will receive six cycles of combination quadruplet therapy (DaraVCD). Six 28-day induction cycles of IV cyclophosphamide (300 mg/m2 on days 1, 8, 15, 22), subcutaneous bortezomib (1.3 mg/m2 on days 1, 8, 15, 22), subcutaneous daratumumab (1800 mg on days 1, 8, 15, 22 of cycles 1-2 and days 1, 15 for cycles 3-6), and oral dexamethasone (40 mg on days 1, 8, 15, and 22).
