About

This research study is evaluating a new drug called "nivolumab" as a possible treatment for smoldering multiple myeloma in order to prevent or postpone development of active multiple myeloma.

• Patients with smoldering multiple myeloma do not have symptoms but are at risk for progressing to active multiple myeloma. Multiple myeloma is a cancer of the plasma cell, which is an important part of the immune system. Patients with active multiple myeloma generally require treatment.

Full description

• This research study is a Phase II clinical trial, which tests the effectiveness of an investigational drug(s). The investigational drugs used in this research study are;

  • nivolumab
  • lenalidomide
  • dexamethasone.

• Preliminary experience suggests that the combination of lenalidomide and dexamethasone may prevent or postpone smoldering multiple myeloma (SMM) from becoming active multiple myeloma. The purpose of this research study is to determine if the addition of nivolumab may improve the rate of prevention in combination with lenalidomide and dexamethasone.

• "Investigational" means that the FDA (the U.S. Food and Drug Administration) has not approved the combination of nivolumab, lenalidomide and dexamethasone as a treatment regimen.

• Lenalidomide is an immunomodulatory drug derived from thalidomide. Lenalidomide works by stopping blood flow to your cancer cells and signaling your cancer cells to die off. The FDA has approved lenalidomide for the treatment of many types of cancer including multiple myeloma, and myelodysplastic syndromes.

• Dexamethasone, also FDA approved, is a type of steroid and is usually combined with other chemotherapy for the treatment of blood cancers, such as myeloma and leukemias.

• Nivolumab is approved by the FDA for some lung cancers, some skin cancers, some kidney cancers, and Hodgkin lymphoma. It is currently being evaluated for use in the treatment of several other types of cancers. Nivolumab may kill or stop cancer cells from growing by blocking a signal in the cells allowing the immune system to fight the cancer. This drug is a human monoclonal antibody, which is a molecule that is made in a laboratory that is designed to act identically to cells in the immune system.

    ----- Increase in serum monoclonal protein by ≥10% on two successive evaluations within a 6 month period

  • t (4;14) or del 17p or 1q gain

  • Increased circulating plasma cells

  • MRI with diffuse abnormalities or 1 focal lesion

  • PET-CT with one focal lesion with increased uptake without underlying osteolytic bone destruction

  • Urine monoclonal light chain excretion ≥500 mg/24 hours

• ECOG Performance Status (PS) 0, 1, or 2 (Appendix A)

• The following laboratory values obtained 21 days prior to registration and confirmed prior to the first dose of study drug:

  • ANC ≥1000/ µL
  • PLT ≥ 50,000/µL. Platelet transfusions to help patients meet eligibility criteria are not allowed within 3 days before study enrollment.
  • Total bilirubin ≤ 1.5 mg/dL (If total is elevated check direct and if normal patient is eligible.)
  • AST ≤ 3 x institutional upper limit of normal (ULN)
  • ALT ≤ 3 x institutional upper limit of normal (ULN)
  • Creatinine ≤ 1.5 mg/dL
  • WBC ≥2000/μL

• Ability to understand and willingness to sign a written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care.

• Female patients who are postmenopausal for at least 1 year before the screening visit or are surgically sterile. Females of childbearing potential* must have a negative serum or urine pregnancy test with a sensitivity of at least 25 mIU/mL within 10 - 14 days and again within 24 hours prior to prescribing lenalidomide for Cycle 1 (prescriptions must be filled within 7 days as required by Revlimid REMS®) 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. Females of reproductive potential must agree to follow instructions for method(s) of contraception for the duration of treatment with any study drug(s) plus 5 half-lives of study plus 30 days (duration of ovulatory cycle) for a total of 120 days post treatment completion. Women must not breastfeed. -- A female of childbearing potential is a sexually mature female who:

  • Has not undergone a hysterectomy (the surgical removal of the uterus) or bilateral oophorectomy (the surgical removal of both ovaries) or
  • Has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (i.e., has had menses at any time during the preceding 24 consecutive months)

• 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.

• Men must agree to use a latex condom during sexual contact with a female of childbearing potential even if they have had a successful vasectomy during the entire study treatment period and through 154 days after the last dose of study drug or agree to practice true abstinence when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence [eg, calendar, ovulation, symptothermal, post-ovulation methods] and withdrawal are not acceptable methods of contraception.)

Exclusion criteria

• No evidence of CRAB criteria* or new criteria of active MM which including the following:

  • Increased calcium levels (corrected serum calcium >0.25 mmol/dL above the upper limit of normal or >.275 mmol/dL) related to MM
  • Renal insufficiency (attributable to MM)
  • Anemia (Hb 2g/dL below the lower limit of normal or <10g/dL) related to MM
  • Bone lesions (lytic lesions or generalized osteoporosis with compression fractures)
  • Bone marrow plasma cells ≥60%
  • Serum involved/uninvolved FLC ratio ≥100, provided the absolute level of the involved free light chain is at least 100 mg/L and repeated twice (light chain smoldering myeloma as described in section 2.4 is not an exclusion criteria).
  • MRI with two or more focal lesions that are at least 5 mm or greater in size --- *Participants with CRAB criteria that are attributable to conditions other than the disease under study may be eligible

• Other concurrent chemotherapy, immunotherapy, radiotherapy, or any ancillary therapy considered investigational. Prior therapy with bisphosphonate is allowed. Prior therapy for smoldering myeloma MM may not be an exclusion criterion, discussion with Principal Investigator must occur before enrolling patients with prior treatments. Prior radiation therapy to a solitary plasmacytoma is allowed.

• Serious medical or psychiatric illness likely to interfere with participation in this clinical study.

• Diagnosed or treated for another malignancy within 2 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, an in situ malignancy, or low-risk prostate cancer after curative therapy.

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Autoimmune disease: Patients with a history of inflammatory bowel disease, including ulcerative colitis and Crohn's Disease, are excluded from this study, as are patients with a history of symptomatic disease (eg, rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, autoimmune pneumonitis, autoimmune vasculitis [eg, Wegener's Granulomatosis]) and motor neuropathy considered of autoimmune origin (e.g. Guillain-Barre Syndrome and Myasthenia, Gravis). Patients with Hashimoto's thyroiditis are eligible to go on study.

• Pregnant or nursing women will be excluded from the study because lenalidomide is an agent with the potential for teratogenic or abortifacient effects.

• History of severe allergic reactions attributed to compounds of similar chemical or biologic composition to Nivolumab or lenalidomide.

• Known seropositive for or active viral infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV). Patients who are seropositive because of hepatitis B virus vaccine are eligible.
