Overview
Brief Summary
This research study is testing the efficacy of an experimental drug combination for people with newly diagnosed multiple myeloma that are eligible for a stem cell transplant.
The names of the study drugs involved in this study are:
- Carfilzomib
- Isatuximab
- Lenalidomide
- Dexamethasone
Detailed Description
This is a phase II study to evaluate the efficacy of once weekly carfilzomib, lenalidomide, dexamethasone, and isatuximab (KRDI) in patients with newly diagnosed, transplant-eligible multiple myeloma. The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits. The study treatment portion of this study is comprised of an induction phase and a maintenance phase. * Induction Phase : * All participants will receive the same study drugs (carfilzomib, isatuximab, lenalidomide, and dexamethasone) for up to 8 cycles. Each cycle is 28 days in length. * All participants will perform stem cell collection after 4 cycles of therapy. Based on the recommendation participants may or may not proceed to an autologous stem cell transplant (SCT) as part of induction therapy. * Maintenance Phase: During maintenance, participants will receive the study treatment for up to two years after induction until progressive disease or unacceptable toxicity It is expected that about 50 people will take part in this research study. This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug combination to learn whether the drug combination works in treating a specific disease. "Investigational" means that the drug combination is being studied. The U.S. Food and Drug Administration (FDA) has approved carfilzomib or isatuximab as a treatment for relapsed/refractory multiple myeloma. The FDA has also approved lenalidomide and dexamethasone as a treatment option for transplant-eligible multiple myeloma. However, the FDA has not approved the combination of isatuximab, carfilzomib, lenalidomide, and dexamethasone as an approved regimen. The combination is considered to be investigational for the treatment of individuals with newly diagnosed multiple myeloma.

Eligibility Criteria
Inclusion Criteria
- •Subject must be at least 18 years of age.
- •Subject must have documented multiple myeloma satisfying the CRAB criteria and measurable disease defined as:
- •Monoclonal plasma cells in the bone marrow ≥10% or presence of a biopsy-proven Plasmacytoma.
- •Measurable disease as defined by any of the following:
- •IgG myeloma: Serum monoclonal paraprotein (M-protein) level ≥.5 g/dL or urine M-protein level ≥200 mg/24 hours; or
- •IgA, IgM, or IgD multiple myeloma: serum M-protein level ≥0.25 g/dL or urine M-protein level ≥200 mg/24 hours; or
- •Light chain multiple myeloma: Serum immunoglobulin free light chain ≥10 mg/dL and abnormal serum immunoglobulin kappa lambda free light chain ratio.
- •Sixty percent or greater clonal plasma cells on bone marrow examination.
- •Serum involved / uninvolved free light chain ratio of 100 or greater, provided the absolute level of the involved free light chain is at least 100 mg/L (a patient's "involved" free light chain - either kappa or lambda - is the one that is above the normal reference range; the uninvolved light chain is the one that typically is in, or below, the normal range).
- •More than one focal lesion on magnetic resonance image (MRI) that is at least 5 mm or greater in size.
Exclusion Criteria
- •Any potential subject who meets any of the following criteria will be excluded from participating in the study.
- •Subject has a diagnosis of primary amyloidosis, monoclonal gammopathy of undetermined significance, or smoldering multiple myeloma. Monoclonal gammopathy of undetermined significance is defined by presence of serum M-protein \<3 g/dL; absence of lytic bone lesions, anemia, hypercalcemia, and renal insufficiency related to the M-protein; and (if determined) proportion of plasma cells in the bone marrow of 10% or less. Smoldering multiple myeloma is defined as asymptomatic MM with absence of related organ or tissue impairment end organ damage.
- •Subject has a diagnosis of Waldenström's disease, or other conditions in which IgM M-protein is present in the absence of a clonal plasma cell infiltration with lytic bone lesions
- •Subject has prior or current systemic therapy or SCT for MM, with the exception of an emergency use of a short course (equivalent of dexamethasone 40 mg/day for a maximum 4 days) of corticosteroids before treatment.
- •Subject has a history of malignancy (other than MM) within 5 years before the date of enrollment (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy that in the opinion of the investigator, with concurrence with the sponsor's medical monitor, is considered cured with minimal risk of recurrence within 5 years).
- •Subject has had radiation therapy within 14 days of enrollment.
- •Subject has had plasmapheresis within 28 days of enrollment.
- •Subject is exhibiting clinical signs of meningeal involvement of MM.
- •Subject has known chronic obstructive pulmonary disease (COPD) (defined as a forced expiratory volume \[FEV\] in 1 second \<60% of predicted normal), persistent asthma, or a history of asthma within the last 2 years (intermittent asthma is allowed). Subjects with known or suspected COPD or asthma must have a FEV1 test during screening.
- •Subject is known to be seropositive for history of human immunodeficiency virus (HIV) or known to have active hepatitis B or hepatitis C.
