Isatuximab with or without Lenalidomide in Treating Patients with High Risk Smoldering Plasma Cell Myeloma
This phase II trial studies how well isatuximab with or without lenalidomide works in treating patients with high risk smoldering plasma cell myeloma. Immunotherapy with monoclonal antibodies, such as isatuximab, may induce changes in the body's immune system and may interfere with the ability of the tumor cells to grow and spread. Lenalidomide may help shrink or slow the growth of smoldering plasma cell myeloma. Giving isatuximab and lenalidomide together may help control the disease.
Inclusion Criteria
- Patients must have histologically confirmed smoldering multiple myeloma (SMM) based on the following criteria; both criteria must be met: * Serum monoclonal protein (IgG or IgA) >= 3 g/dL or urinary monoclonal protein >= 500 mg per 24 hours and/or clonal bone marrow plasma cells 10-60% * Absence of myeloma defining events or amyloidosis
- Additionally, patients must meet criteria for high risk of progression to multiple myeloma by Programa para el Tratamiento de Hemopatias Malignas (PETHEMA) criteria (patients must have at least 2 risk factors present): * >= 95% abnormal plasma cells/total plasma cells in bone marrow compartment (this is measured as a percentage of the total abnormal versus normal plasma cells in the bone marrow compartment using standard flow cytometry of the bone marrow aspirate; having >= 95% abnormal plasma cells/total plasma cells constitutes a risk factor for progression to multiple myeloma by PETHEMA criteria) * Immunoparesis (this term refers to the patient having low uninvolved immunoglobulins in peripheral blood, for example if a patient has IgA smoldering multiple myeloma, then either having a low IgM and/or low IgG will qualify as a risk factor for progression to multiple myeloma) ** 2 of 2 risk factors: high risk for progression at a rate of 72% at 5 years
- Creatinine clearance (CrCl) >= 40 ml/min; CrCl will be calculated using the modification of diet in renal disease (MDRD) equation
- Age >= 18 years. Because no dosing or adverse event data are currently available on the use of isatuximab in patients < 18 years of age, children are excluded from this study
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Absolute neutrophil count (ANC) >= 1.0 x 10^9 /L
- Hemoglobin more or equal than 2 grams below the institutional level of normal
- Platelet count >= 90 x 10^9/L
- Platelet and blood transfusions are allowed on protocol; growth factors, including granulocyte colony stimulating factors and erythropoietin are allowed
- Bilirubin < 1.5 x the upper limit of normal (ULN)
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3.0 x ULN
- Females of childbearing potential and male subjects with female partners of childbearing potential must agree to avoid pregnancy by using an adequate method of contraception (2 barrier method or 1 barrier method with a spermicide or intrauterine device for 10-14 days prior to screening, during and 5 months after the last dose of isatuximab; adequate methods of contraception are provided as examples; other acceptable and effective methods of birth control are also permitted (e.g., abstinence)
- Men must agree to not donate sperm while on the study and for at least 5 months after the last dose of isatuximab; women of child bearing potential must have a negative serum/urine pregnancy test result within 10-14 days prior to the first administration of isatuximab and at the end of treatment visit; a negative urine pregnancy test is required prior to each subsequent isatuximab dose administration
- Subjects must be able to give informed consent
Exclusion Criteria
- Evidence of myeloma defining events or biomarkers of malignancy due to underlying plasma cell proliferative disorder meeting at least one of the following: * Hypercalcemia: serum calcium > 0.25 mmol/L (> 1 mg/dL) higher than the upper limit of normal or > 2.75 mmol/L (> 11 mg/dL) * Renal insufficiency: creatinine clearance < 50 ml/min or serum creatinine > 2 mg/dL * Anemia: hemoglobin value < 10 g/dL or 2 g/dL < normal reference * Bone lesions: one or more osteolytic lesions on skeletal radiography, computerized tomography (CT) or 2-deoxy-2[F-18] fluoro-D-glucose positron emission tomography CT (PET-CT) * Clonal bone marrow plasma cell percentage >= 60% * Involved: uninvolved serum free light chain ratio >= 100 measured by Freelite assay (The Binding Site Group, Birmingham, United Kingdom [UK]) * > 1 focal lesions on MRI studies (each focal lesion must be 5 mm or more in size)
- Bisphosphonates are permitted, including pamidronate, zoledronic acid, alendronate, ibandronate, risedronate
- Treatment with corticosteroids is not permitted, unless the patient is on a stable chronic dose of inhaled steroids to treat respiratory diseases or on stable chronic steroid replacement therapy for endocrinology disorders
- Radiotherapy is not permitted.
- Prior or concurrent treatment for smoldering multiple myeloma with chemotherapy agents approved for the treatment of smoldering multiple myeloma or CD38 drugs is not permitted
- Plasma cell leukemia
- Pregnant or lactating females; Because there is a potential risk for adverse events in nursing infants secondary to treatment of the mother with isatuximab, breastfeeding should be discontinued if the mother is treated with isatuximab; these potential risks may also apply to other agents used in this study
- Active hepatitis B or C infection
- Known human immunodeficiency virus (HIV) infection
- Intolerance to infused protein products, sucrose, histidine or polysorbate 80
- Concurrent treatment with other anti-cancer therapy is not permitted
- Patients must not have uncontrolled intercurrent illness including hypertension, symptomatic congestive heart failure, unstable angina, uncontrolled cardiac arrhythmia. Patients should not have New York Heart Association classification III or IV heart failure at baseline
- Uncontrolled intercurrent illness including but not limited to active infection or psychiatric illness/social situations that would compromise compliance with study requirements
- Contraindication to any concomitant medication, including pre-medications or hydration given prior to therapy
- Major surgery within 1 month prior to enrollment
- Patients with pre-existing pulmonary uncontrolled disease will be excluded; uncontrolled refers to patients having had at least one hospitalization due to pulmonary disease (for example, asthma, chronic obstructive pulmonary disease) within the 6 months prior to enrollment in the study; patients with previous history of pneumonitis will be excluded

PRIMARY OBJECTIVE:
I. To determine the rate of response according to the International Myeloma Working Group Criteria.
SECONDARY OBJECTIVES:
I. To determine progression free survival (PFS) at 2 years.
II. To determine overall survival (OS).
III. To determine duration of response (DOR).
IV. To determine the clinical benefit rate (CBR).
V. To evaluate safety of single agent treatment in this population.
VI. To evaluate safety of combination of isatuximab-lenalidomide-dexamethasone in this population.
VII. To evaluate the immunogenicity of isatuximab.
OUTLINE: Patients are assigned to 1 of 2 arms.
COHORT I (SINGLE AGENT) (TERMINATED JANUARY 2020): Patients receive isatuximab intravenously (IV) over 5 hours on day 1 of cycle 1, and over 3 hours thereafter on days 8, 15, and 22 of cycle 1, on days 1 and 15 of cycles 2-6, and on day 1 of subsequent cycles. Treatment repeats every 28 days for up to 30 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy, positron emission tomography (PET)-computed tomography (CT) scan, magnetic resonance imaging (MRI), skeletal survey, and blood sample collection throughout the study.
COHORT II (COMBINATION): Patients receive isatuximab as in Cohort I, and lenalidomide orally (PO) once daily (QD) on days 1-21. Treatment repeats every 28 days for up to 30 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo bone marrow aspiration and biopsy, PET-CT scan, MRI, skeletal survey, and blood sample collection throughout the study.
After completion of study treatment, patients are followed up to 4 weeks and then every 6-12 months.
