Brief Summary

This study seeks to determine whether addition of an allogeneic myeloma vaccine can augment clinical responses to lenalidomide in patients with near complete remission (nCR), or complete remission (CR) leading to a significant improvement in progression-free survival.This main objective of this study is to compare the 2-year progression free survival of patients with multiple myeloma in CR or nCR, treated with lenalidomide plus an allogeneic myeloma vaccine in combination with lenalidomide (with or without Prevnar vaccine) or versus placebo in combination with lenalidomide (control arm).

Detailed Description

This is a single institution, three- arm, randomized controlled, Phase II study examining the clinical efficacy of an allogeneic GM-CSF secreting myeloma vaccine in combination with lenalidomide (with or without Prevnar) compared to lenalidomide and placebo (control arm).

Patients enrolled in the study must have two disease measurements (including the last one) consistent with a near complete remission (M-spike negative with persistence of immunofixation), or complete remission (M-spike negative, negative immunofixation, and <5% clonal plasma cells on bone marrow) per criteria for response in a 3 month period. All patients must be minimal residual disease (MRD) positive by NGS sequencing at enrollment.

Prior to enrollment, patients will have been treated with a lenalidomide containing regimen for a minimum of 6 cycles. All patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment.

Patients will be randomized to receive either an allogeneic myeloma vaccine and Prevnar vaccine in combination with lenalidomide, or allogeneic myeloma vaccine without Prevnar vaccine in combination with lenalidomide, or lenalidomide in combination with placebo. Patients will receive allogeneic myeloma vaccine or placebo injections on day 14 (+/-3 days) of cycles 1, 2, 3 and 6 from enrollment, and then annually thereafter for up to 3 years. If assigned to allogeneic myeloma vaccine plus Prevnar vaccine arm, Prevnar-13 will be administered with each allogeneic myeloma vaccine. If assigned to either of the two arms that do not include Prevnar, then patients will receive a placebo in lieu of Prevnar on the same schedule. All patients will be followed for a minimum of 3 years.

Study Groups

Lenalidomide plus GM-CSF Vaccine plus Prevnar13

Patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment.

Patients assigned to vaccine therapy will receive injections on day 14 (+/-3 days) of cycles 1, 2, 3 and 6 from enrollment, and then annually thereafter. Prevnar vaccine will be administered with the GM-CSF vaccine administration.

Group Type: EXPERIMENTAL

GM-CSF vaccine

Intervention Type: BIOLOGICAL

Each vaccination will consist of three total intra-dermal injections, on day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months in the right and left anterior upper thighs, and one in the non-dominant upper arm (unless contraindicated). In the event that the specified limb is contraindicated, the dominant arm may be used. Vaccine injection sites shall be at least 5 cm at needle entry from the nearest neighbor. The approximate volume of each vaccination injection is approximately 0.7-0.8ml.

Lenalidomide

Intervention Type: DRUG

Patients will be continued on the same dose of lenalidomide as they were prior to being enrolled in the study. Doses of lenalidomide for investigation can vary from 5-25 mg/day, orally on days 1 - 21 followed by 7 days rest (28 day cycle).

Prevnar13

Intervention Type: DRUG

Prevnar will be administered at the same time points as the GM-CSF vaccine (day 14 of cycles 1, 2, 3, 6 and annually for a minimum of 36 months), but on the opposite arm from GM-CSF vaccine.

Lenalidomide Only

Patients will continue on a standard dose of lenalidomide as a single agent until progression, or treatment limiting toxicity, following enrollment. Patients will also get placebo GM-CSF vaccine and placebo prevnar13. Placebo will be saline.

Group Type: PLACEBO_COMPARATOR

Lenalidomide

Intervention Type: DRUG

Patients will be continued on the same dose of lenalidomide as they were prior to being enrolled in the study. Doses of lenalidomide for investigation can vary from 5-25 mg/day, orally on days 1 - 21 followed by 7 days rest (28 day cycle).
