Title
Phase III study of Isatuximab-Carfilzomib-Lenalidomide-Dexamethasone (Isa-KRd) versus Carfilzomib-Lenalidomide-Dexamethasone (KRd) in newly diagnosed multiple myeloma patients eligible for autologous stem cell transplantation (IsKia trial)Study map
Overview / Summary
This protocol is a phase III study designed to compare the efficacy and the safety of Isa-KRd induction, transplant, Isa-KRd post ASCT consolidation and Isa-KRd light consolidation vs KRd induction, transplant, KRd post ASCT consolidation and KRd light consolidation
After confirmation of eligibility criteria patients will be randomized to one of the 2 treatment groups in a 1:1 randomization ratio: Isatuximab-carfilzomib-lenalidomide-dexamethasone (ARM A) or carfilzomib-lenalidomide-dexamethasone (ARM B) for 4 cycles followed by ASCT. Each arm will receive then 4 cycles of post ASCT consolidation followed by 12 cycles of light consolidation with isatuximab-carfilzomib-lenalidomide-dexamethasone (ARM A) or carfilzomib-lenalidomide-dexamethasone (ARM B)

- Patient has measurable disease as defined by any one of the following:
– Serum monoclonal paraprotein (M-protein) level ≥1.0 g/dL or urine M-protein level ≥200 mg/24 hours; or
– Light chain multiple myeloma without measurable disease in the serum or the urine: Serum immunoglobulin FLC ≥10 mg/dL and abnormal serum immunoglobulin kappa lambda FLC ratio. - Life expectancy ≥ 3 months
- ECOG status ≤2
- Clinical laboratory values meeting the following criteria during the Screening Phase:
- Adequate hepatic function, with serum (alanine aminotransferase) ALT ≤ 2.5 times the upper limit of normal (ULN), AST (aspartate transaminase) ≤ 2.5 x the ULN
- Serum direct bilirubin ≤ 1.5 ULN) (except in subjects with congenital bilirubinemia, such as Gilbert syndrome, direct bilirubinemia ≤ 1.5 ULN)
- Absolute neutrophil count (ANC) ≥ 1.0 × 109/L
- Platelet count ≥ 75× 109/L (≥ 50× 109/L if myeloma involvement in the bone marrow is > 50%) and no platelet infusion in the 1 week prior to screening platelet count
- Creatinine clearance (CrCl) ≥ 30 mL/minute. Creatinine clearance should be calculated using eGFR (Modified Diet in Renal Disese [MDRD])
- Corrected serum calcium ≤ 13.5 mg/dL (3.4 mmol/L)
- LVEF ≥ 40%. 2-D transthoracic echocardiogram (ECHO) is the preferred method of evaluation. Multigated Acquisition Scan (MUGA) is acceptable if ECHO is not available.
- Females of childbearing potential (FCBP)* complies with the conditions of the Pregnancy Prevention Plan, including confirmation that she has an adequate level of understanding and must agree to ongoing pregnancy testing and to practice contraception or true abstinence. FCBP must use a highly effective and an additional barrier contraception method simultaneously for 4 weeks before starting therapy, during treatment and dose interruptions and for 5 months after the last dose of study drugs.
- Male subjects must agree to practice contraception if sexually active with FCBP during the treatment and for 5 months after the last dose of study drugs. Males must agree to refrain from donating sperm for at least 90 days after the last dose of carfilzomib and for at least 5 months after the last dose of isatuximab.
*Note 1: a FCBP is a woman who:
1) has achieved menarche at some time point,
2) has not undergone a hysterectomy or bilateral oophorectomy or,
3) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 24 consecutive months (ie, has had menses at any time in the preceding 24 consecutive months).
Note 2: true abstinence is acceptable when this is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
