• Status: Active, not recruiting
• Trial end date: 2023-01-01
• Target enrollment: 0
• Participant gender: All

Summary

Patients with newly diagnosed multiple myeloma (NDMM) who failed to achieve at least a minimal response (MR) after 2 cycles or a partial response (PR), after 4 cycles of a bortezomib-containing therapy, or progress on therapy during first 4 cycles (response defined by international Myeloma Working Group [IMWG] criteria), will be treated with a quadruple regimen comprised of: Daratumumab 16 mg/Kg weekly during cycles 1-2, q14 days during cycles 3-6, thereafter monthly (1st dose cycle 1 may be split over 2 days); Once-weekly intravenous (IV) administration of Carfilzomib on days 1, 8, 15, of cycle numbers 1-9 and Days 1 and 15 only of cycle numbers 10-18, at a dose of 20 mg/m2 on day 1 of cycle 1; at dose of 56 mg/m2 on all subsequent once weekly dosing days, alongside concomitant treatment with twice-weekly IV or oral dexamethasone 20mg administered on Days 1-2, 8-9, 15-16, and 22-23 of a 28-day cycle, for cycles 1-2 followed by weekly 20 mg dexamethasone on subsequent cycles; and oral Lenalidomide 25 mg, administered on days 1-21 of a 28-day cycle. On treatment days that require both Carfilzomib and Daratumumab infusions, Carfilzomib will be administrated prior to Daratumumab administration. All patients will undergo frailty assessment based on IMWG recommendations, and will be classified as fit, intermediate-fit and frail. Frail patients will receive Lenalidomide dose adjustment to 15 mg (throughout the study, from cycle 1 and on), and dexamethasone at 10 mg x 2/week cycles 1-2 followed by 10 mg/week for subsequent cycles. The quadruple regimen will be administered for 18 cycles, followed by long-term follow-up in which patients will receive standard of care treatment with Lenalidomide/dexamethasone (Rd) treatment, unless disease progression, the physician decides otherwise, the patient suffers from unacceptable toxicity, withdraws consent, or dies (whichever occurs first).

• Serum free light chain (SFLC) ≥ 100 mg/L (involved light chain) and an abnormal serum kappa/lambda ratio, or

• In patients with immunoglobulin A (IgA) type MM, whose disease can only be reliably measured by serum quantitative immunoglobulin (qIgA), qIgA ≥ 750 mg/dL (0.75 g/dL)

6. Male/female, ≥ 18 years of age

7. Eastern Cooperative Oncology Group Performance Status (ECOG PS) of 0-2

8. Adequate hepatic function within 28 days prior to treatment initiation, with bilirubin < 1.5 times the upper limit of normal (ULN), and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 3 times the ULN

9. Left ventricular ejection fraction ≥ 40%

10. Absolute neutrophil count (ANC) ≥ 1500/mm3 within 28 days prior to enrollment, and reconfirmed within 7 days prior to first dose. Screening ANC should be independent of growth factor support for ≥ 1 week.

11. Hemoglobin ≥ 8.0 g/dL within 28 days prior to treatment initiation, and reconfirmed within 7 days prior to first dose. Use of erythropoietic stimulating factors and red blood cell (RBC) transfusions per institutional guidelines is allowed, however most recent RBC transfusion may not have been done within 7 days of obtaining Screening hemoglobin.

12. Platelet count ≥ 50,000/mm3 (≥ 30,000/mm3 if myeloma involvement in the bone marrow is > 50%) within 28 days prior of treatment initiation, and reconfirmed within 7 days prior to first dose. Patients should not have received platelet transfusions for at least 1 week prior to obtaining the Screening platelet count.

13. Calculated or measured creatinine clearance (CrCL) of ≥ 30 mL/min within 28 days prior to treatment initiation. Calculation should be based on standard formula such as the Cockcroft and Gault: [(140 - Age) x Mass (kg) / (72 x Creatinine mg/dL)]; multiply result by 0.85 if female.

15. Females of childbearing potential (FCBP) must have a negative serum pregnancy test within 21 days prior to treatment initiation and agree to use an effective method of contraception throughout the treatment period and for 3 months following last dose. Female of childbearing potential is defined as a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy or 2) has not been naturally postmenopausal (amenorrhea following cancer therapy does not rule out childbearing potential) for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).

16. Male patients must use an effective barrier method of contraception during the treatment period and for 3 months following the last dose, if sexually active with a FCBP -
