You may be able to join this trial if you:

The following criteria is a partial list of reasons why patients may be eligible to participate in this clinical trial. Further evaluation with a medical professional is required.

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.
  • Newly diagnosed and considered candidate for high-dose chemotherapy with stem cell transplant.
  • Subject must have an Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2.
  • Subject must have pretreatment clinical laboratory values meeting the following criteria during the Screening Phase:
    • hemoglobin ≥ 7.5 g/dL (≥ mmol/L; prior RBC transfusion or recombinant human erythropoietin use is permitted);
    • absolute neutrophil count ≥1.0 x 109/L (granulocyte colony stimulating factor [GCSF] use is permitted);
    • platelet count ≥70 x 109/L for subjects in whom <50% of bone marrow nucleated cells are plasma cells; otherwise platelet count >50 × 109/L (transfusions are not permitted to achieve this minimum platelet count)
    • aspartate aminotransferase (AST) ≤2.5 x upper limit of normal (ULN);
    • alanine aminotransferase (ALT) ≤2.5 x ULN;
    • total bilirubin ≤2.0 x ULN, except in subjects with congenital bilirubinemia, such as Gilbert syndrome (direct bilirubin ≤2.0 x ULN)
    • creatinine clearance ≥30 mL/min
    • corrected serum calcium ≤14 mg/dL (≤3.5 mmol/L); or free ionized calcium <6.5 mg/dL (<1.6 mmol/L).
  • Women of childbearing potential must commit to either abstain continuously from heterosexual sexual intercourse or to use 2 methods of reliable birth control simultaneously. This includes one highly effective form of contraception (tubal ligation, intrauterine device [IUD], hormonal [birth control pills, injections, hormonal patches, vaginal rings or implants] or partner's vasectomy) and one additional effective contraceptive method (male latex or synthetic condom, diaphragm, or cervical cap). Contraception must begin 4 weeks prior to dosing. Reliable contraception is indicated even where there has been a history of infertility, unless due to hysterectomy or bilateral oophorectomy.
  • A man who is sexually active with a woman of childbearing potential must agree to use a latex or synthetic condom, even if they had a successful vasectomy. All men must also not donate sperm during the study, for 4 weeks after the last dose of lenalidomide, for 90 days after the last dose of carfilzomib, and for 4 months after the last dose of isatuximab.
  • A woman of childbearing potential must have 2 negative serum or urine pregnancy tests at Screening, first within 10 to 14 days prior to dosing and the second within 24 hours prior to dosing.
  • Each subject (or their legally acceptable representative) must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study. Subject must be willing and able to adhere to the prohibitions and restrictions specified in this protocol, as referenced in the ICF.

  • Subject is known or suspected of not being able to comply with the study protocol (eg, because of alcoholism, drug dependency, or psychological disorder). Subject has any condition for which, in the opinion of the investigator, participation would not be in the best interest of the subject (eg, compromise the well-being) or that could prevent, limit, or confound the protocol specified assessments.

A Phase II Study of Once Weekly Carfilzomib, Lenalidomide, Dexamethasone, and Isatuximab in Newly Diagnosed, Transplant-Eligible Multiple Myeloma (The SKylaRk Trial)Clinically Relevant Abstract

December 11, 2022

Fifty patients enrolled between August 2020 and February 2022. Median age at study entry was 59 years (range 39-70) and 27 (54%) were male. Twenty-three (46%) of patients had high-risk cytogenetics, 6 (12%) were ISS III, and 2 (4%) were R-ISS III. Median follow up was 10.8 months. Of the 47 patients evaluable for response after 4 cycles, the ORR was 100% and 89% (42/47) achieved a very good partial response (VGPR) or better and 40% (19/47) a CR. Of the 47 patients evaluable for response, MRD results were available after C4 for 28 patients achieving a VGPR or better. Of those, 43% (12/28) were MRD negative at 10-5 and 32% (9/28) at 10-6. The 12-month PFS and OS were 97.9% (95% CI 86.1% -99.7%). Most common grade 3 or 4 side effects (≥2 patients) were neutropenia (24%), elevated alanine aminotransferase (10%), acute kidney injury (6%), and thrombocytopenia (6%). Grade 1-2 infusion-related reactions were seen in 20%, no grade 3. Grade 1-2 hypertension was seen in 48% with one grade 3. There was one death assessed as unrelated. Two patients were removed from study for acute kidney injury.
