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).

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.

Eligibility

Yes No Not Sure

Inclusion Criteria

Myeloma eligibility criteria are the following
Near complete remission (nCR) for ≥ 3 months defined as no measurable M-spike, and a positive serum immunofixation
For patients with a light chain only myeloma, they will be in deemed to be in a CR if they meet criteria for CR by International Myeloma Working Group (IMWG) consensus criteria 2016
For patients with a light chain only myeloma that meet criteria for Very Good Partial Response (VGPR) by IMWG consensus criteria 2016 and are IFE -ve (negative serum immunofixation), they will be considered to be in a near complete remission (nCR)
Or complete remission (CR) (no measurable M-spike, immunofixation negative and bone
marrow plasma cells <5%)
All patients must be MRD positive at 10-4 or greater by NGS sequencing at enrollment
NDMM or RMM in nCR or CR having completed a minimum of 6 cycles of a lenalidomide based regimen for a minimum of ≥ 3 months
NDMM or RMM a patients who have been off corticosteroids for ≥ 4 weeks
Age >18 years
Patients with NDMM or RMM who have had autologous stem cell transplant are eligible, but must be ≥ 12 months from transplant
ECOG performance scores 0-2
History of measurable serum or urine M protein or free light chains
All patients must be currently taking Revlimid at screening
Life expectancy greater than 12 months
Corrected serum calcium < 11 mg/dL, and no evidence of symptomatic hypercalcemia
Serum creatinine< 2 mg/dl
Total bilirubin <= 1.5 x ULN
AST (SGOT) and ALT (SGPT) <= 3 x ULN
ANC >1000/µL
Ability to comprehend and have signed the informed consent
Have previously agreed to continue on maintenance therapy with lenalidomide concurrent with vaccine administration until disease progression, or clinical indication to cease therapy
Platelet >100,000/µL
Disease free of prior malignancies for at least 5 years with exception of currently treated basal cell or squamous cell carcinoma of the skin, or carcinoma "in situ" of the uterus, cervix or breast
Females of childbearing potential (FCBP) must have a negative serum or urine pregnancy test with a sensitivity of at least 50 mIU/mL within 10 - 14 days prior to starting lenalidomide with each cycle (prescriptions must be filled within 7 days) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide. FCBP must also agree to ongoing pregnancy testing. Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy
Able to take prophylactic anticoagulation (aspirin 81 or 325 mg/daily or, for patients intolerant to ASA, warfarin or low molecular weight heparin)
All study participants must be registered into the mandatory Revlimid REMS® program, and be willing and able to comply with the requirements of the REMS® program
Females of reproductive potential must adhere to the scheduled pregnancy testing as required in the Revlimid REMS® program

Exclusion Criteria

Disease progression after stopping corticosteroids as defined as the appearance of a detectable serum or urine M-spike, or an absolute increase of >10 mg/dl between involved and uninvolved light chains, in the absence of measurable serum or urine M-protein
