Summary

This is a Phase II study of daratumumab based therapies for older adults with multiple myeloma.

Detailed description

In this response adapted approach, older adults with newly diagnosed symptomatic multiple myeloma will receive daratumumab and dexamethasone for 2 months. Patients who achieve a partial response or better will continue on daratumumab. Patients who achieve less than a partial response will have lenalidomide or bortezomib added to their therapy. Patients who experience progressive disease on daratumumab after the initial 2 months of monotherapy or on the combination of daratumumab and either lenalidomide or bortezomib will come off study

Conditions

• Multiple Myeloma

Interventions

Type	Name	Description
DRUG	Daratumumab Injection	Patient will receive daratumumab (1800 mg in 15 ml) administered by manual subcutaneous injections weekly for the first 8 weeks, every other week for the next 16 weeks and every 4 weeks after.
DRUG	Dexamethasone Oral	The dexamethasone starting dose will be 20 mg PO once a week. Commercial dexamethasone will be used. Dexamethasone is often supplied in 4 mg tablets. Accordingly, patients will take 5 (4 mg tablets) one day of the week prior to the administration of daratumumab if this corresponds to a daratumumab dosing days. In non daratumumab dosing days, dexamethasone will be taken by the patient at home, usually in the morning with breakfast.
DRUG	Lenalidomide Pill	Lenalidomide will be given orally on days 1-21 of a 28 days cycle. The starting dose of lenalidomide will be based on the patient creatinine clearance per the package insert. Specifically patients with a creatinine clearance ≥ 50 ml/min will receive 25 mg of lenalidomide PO Days 1-21. Patients with a creatinine clearance ≥ 30 but less than 50 ml/min will receive 10 mg of lenalidomide. Patients with a creatinine clearance \< 30 ml/min are not eligible but patients who experience a deterioration in the renal function during screening or treatment may continue on lenalidomide therapy as long as the risk / benefit profile is deemed acceptable, that study therapy is in the best interest of the patient and after discussion with the study principal investigator / sponsor.
DRUG	Bortezomib Injection	Bortezomib will be given weekly subcutaneously in an effort to decrease the toxicity of the therapy. Specifically patients will receive a starting dose of bortezomib of 1.3 mg/m\^2 Days 1,8,15 of a 28 day cycle. Bortezomib will be administered in the cancer center per standard of care procedures.
