pembrolizumab, lenalidomide, and dexamethasone in treating patients with newly diagnosed multiple myeloma eligible for stem cell transplant

Conditions: Plasma Cell Myeloma

Summary: this phase ii trial studies how well pembrolizumab, lenalidomide, and dexamethasone work in treating patients with newly diagnosed multiple myeloma that are eligible for stem cell transplant. monoclonal antibodies, such as pembrolizumab, may interfere with the ability of cancer cells to grow and spread. drugs used in chemotherapy, such as lenalidomide and dexamethasone, 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. giving pembrolizumab, lenalidomide, and dexamethasone may work better in treating patients with multiple myeloma.

primary objectives: i. to determine the very good partial response (vgpr) or better response rate (\>= vgpr) after 4 cycles of pembrolizumab added to standard doses of lenalidomide and dexamethasone, when used as initial therapy in patients with previously untreated symptomatic multiple myeloma (mm) in patients, who are considered eligible for stem cell transplantation. secondary objectives: i. to determine the \>= partial response (pr) rate after 4 cycles of treatment with pembrolizumab added to standard doses of lenalidomide and dexamethasone. ii. to determine the \>= vgpr response rate at any time during treatment with pembrolizumab added to standard doses of lenalidomide and dexamethasone. iii. to determine the progression free survival and overall survival among patients with previously untreated symptomatic mm following treatment with the combination of pembrolizumab, lenalidomide and dexamethasone. iv. to determine the toxicities associated with pembrolizumab added to standard doses of lenalidomide and dexamethasone in patients with previously untreated symptomatic mm. v. to determine the success rate of stem cell collection following initial therapy with the combination of pembrolizumab, lenalidomide and dexamethasone in patients with newly diagnosed mm. tertiary objectives: i. pdl-1 expression on myeloma cells and non-tumor cell compartments from the bone marrow will be assessed at baseline. ii. measures of t-cell activation / exhaustion will be assessed at baseline and after cycle 1, cycle 2, cycle 3, and cycle 4. iii. natural killer (nk) cell function and numbers will be evaluated at baseline and after cycle 1, cycle 2, cycle 3, and cycle 4. outline: patients receive lenalidomide orally (po) daily on days 1-21 and dexamethasone po daily on days 1, 8, 15, and 22. courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. patients also receive pembrolizumab intravenously (iv) over 30 minutes on days 1 and 22 of course 1, day 15 of course 2, and day 8 of course 3. courses 1-3 repeat beyond 3 courses in the absence of disease progression or unacceptable toxicity. patients may undergo stem cell transplantation after 4 courses of treatment. after completion of study treatment, patients are followed up every 3 months or 6 months for up to 3 years.

only * willing to follow strict birth control measures as suggested by the study * female patients: if they are of childbearing potential, must agree to one of the following: * practice 2 effective methods of contraception, at the same time, from the time of signing the informed consent form through 90 days after the last dose of study drug, and must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, or * agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject (periodic abstinence \[e.g., calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception) * male patients: even if surgically sterilized (i.e., status post-vasectomy), must agree to one of the following: * agree to practice effective barrier contraception during the entire study treatment period and through 120 days after the last dose of study drug, or * must also adhere to the guidelines of any treatment-specific pregnancy prevention program, if applicable, or * agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject (periodic abstinence \[e.g., calendar, ovulation, symptothermal, post-ovulation methods\] and withdrawal are not acceptable methods of contraception) * willing to return

and blood specimens exclusion criteria: * monoclonal gammopathy of undetermined significance (mgus) or smoldering myeloma * prior cytotoxic chemotherapy or corticosteroids for the treatment of multiple myeloma * note: prior corticosteroid use for the treatment of non-malignant disorders is permitted * diagnosed or treated for another malignancy =\< 2 years before study enrollment or

undergone complete resection * any of the following: * pregnant women * nursing women * men or women of childbearing potential who are unwilling to employ adequate contraception * other co-morbidity which would interfere with patient's ability to participate in trial, e.g. uncontrolled infection, uncompensated heart or lung disease * other concurrent chemotherapy or any ancillary therapy
