Summary

This phase III trial compares the effect of usual treatment (lenalidomide) to using daratumumab/rHuPH20 plus the usual treatment after stem cell transplantation in patients with multiple myeloma. This drug combination may help patients live longer after their stem cell transplant. Another purpose of this study is to learn if the presence and amount of minimal residual disease (MRD) can help doctors predict when a patient’s multiple myeloma will get worse. MRD is the name for the small number of cancer cells that remain in the patient even after their multiple myeloma has been treated and they have no symptoms of the disease. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with daratumumab/rHuPH20, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and daratumumab/rHuPH20 may work better in treating patients with multiple myeloma compared to lenalidomide alone.

Objectives

PRIMARY OBJECTIVE:
I. To compare overall survival (OS) between the two treatment arms with lenalidomide as the comparator arm and lenalidomide + daratumumab/rHuPH20 as the experimental arm in post-autologous transplant multiple myeloma (MM) patients.

SECONDARY OBJECTIVES OF FIRST RANDOMIZATION:
I. To compare the best overall response rate (ORR), including partial remission (PR), very good partial remission (VGPR), and complete remission (CR, stringent [s]CR) in the subset of patients not in PR at randomization to lenalidomide versus lenalidomide + daratumumab/rHuPH20 in this patient population.
II. To compare progression-free survival (PFS) between the study arms in this patient population.
III. To evaluate MRD-negativity on the two treatment arms at randomization (Registration Step 2), and to compare MRD-negativity at 12, 24 (second randomization), 36, and 48 months after first randomization between lenalidomide and lenalidomide + daratumumab/rHuPH20 in this patient population.
IV. To compare toxicities and tolerability of long term therapy between the study arms.

OBJECTIVES OF SECOND RANDOMIZATION:
I. To compare overall survival (OS) between minimal residual disease (MRD) negative patients randomized to continued lenalidomide versus (vs.) discontinued lenalidomide from the time of second randomization in this patient population.
II. To compare overall survival (OS) between MRD negative patients randomized to continued lenalidomide + daratumumab/rHuPH20 vs. discontinued lenalidomide + daratumumab/rHuPH20 from time of second randomization in this patient population.

ADDITIONAL OBJECTIVE:
I. To report the findings of the 24-month MRD analysis as early as 24 months after all patients have been accrued.

OUTLINE: Patients are randomized to 1 of 2 arms after undergoing autologous stem cell transplantation.

ARM I: Patients receive lenalidomide orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients who achieve MRD negativity are then randomized to continue lenalidomide treatment for 5 years or stop treatment. Patients who are MRD positive continue lenalidomide treatment for 5 years in the absence of disease progression or unacceptable toxicity.

ARM II: Patients receive lenalidomide PO QD on days 1-28. Patients also receive daratumumab/rHuPH20 subcutaneously (SC) over 3-5 minutes on days 1, 8, 15 and 22 of cycles 1-2, days 1 and 15 for cycles 3-6, and day 1 for subsequent cycles. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients who achieve MRD negativity are then randomized to continue lenalidomide and daratumumab/rHuPH20 treatment for 5 years or stop treatment. Patients who are MRD positive continue lenalidomide and daratumumab/rHuPH20 treatment for 5 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 2 or 6 months for 7 years, and then annually for up to 15 years after Registration Step 2.
