Conditions: Multiple Myeloma, Newly Diagnosed, Multiple Myeloma (MM)
Sex: All
Ages: 19 Years – N/A
Healthy volunteers: No
Phase: PHASE2
Enrollment: 100
Sponsor: SCRI Development Innovations, LLC
Location: University of Alabama at Birmingham Birmingham Alabama
Summary
This is an open-label, multi-site, Phase II randomized trial with response-adaptive design for newly diagnosed multiple myeloma (NDMM) participants who have had prior induction therapy. The primary objective of this study is to compare the rates of achieving undetectable measurable residual disease (MRD) in the bone marrow with elranatamab and daratumumab employed as post-induction consolidation and maintenance treatment (Arm A) versus autologous stem cell transplant (ASCT) followed by lenalidomide and daratumumab treatment (Arm B).
Eligibility Criteria
Inclusion Criteria:
1. Age \>18 years with no upper age limit.
2. Newly diagnosed multiple myeloma with indication for initiation of therapy diagnosed within last 12 months. Pretreatment parameters necessary for disease characterization and response assessment must be available.
3. Eligible for ASCT according to institutional policy as evaluated by investigator.
4. Eastern Cooperative Oncology Group (ECOG) performance status 0-1 (Appendix A).
5. Prior induction therapy including one PI, lenalidomide, and an anti-CD38 mAb for 16-24 weeks, obtaining at least a partial response (PR).
6. Measurable disease meeting at least 1 of the following criteria (at the time of diagnosis):
a. Serum monoclonal (M) protein ≥1.0 g/dl (≥0.5 g/dl if IgA, IgD, IgE or IgM MM).
b. ≥200 mg of M protein/24h in the urine. c. Difference between affected and unaffected free light chain ≥10 mg/dL with abnormal kappa to lambda ratio.
7. Have trackable clonogenic sequence using ClonoSEQ® (Seattle, WA) identified from a high disease burden sample obtained as SoC and enabling MRD testing during screening phase.
8. Have clinical laboratory values meeting the following criteria during the Screening Phase and also at start of administration of study treatment:
• Hemoglobin ≥8g/dL without prior red blood cells (RBC) transfusion within 14 days before the laboratory test; recombinant human erythropoietin use is permitted
• Platelets ≥75,000/µl
• Absolute neutrophil count ≥1,000/µl (prior growth factor support is permitted but must be without support for 7 days for granulocyte colony stimulating factor (G-CSF) or granulocyte-macrophage colony stimulating Factor (GM-CSF) and for 14 days for pegylated G-CSF before screening lab test
• Aspartate aminotransferase and alanine aminotransferase ≤2.5 × upper limit of normal (ULN)
* Renal function: Creatinine clearance (CrCl) ≥40 mL/min based on calculation using Cockcroft-Gault formula or measured by a 24-hour urine collection.
* Total bilirubin ≤2 × ULN, except in participants with congenital bilirubinemia, such as Gilbert syndrome (in which case direct bilirubin ≤3 × ULN is required)
* Serum calcium corrected for albumin ≤14 mg/dL (≤3.5 mmol/L) or free ionized calcium ≤6.5 mg/dL (≤1.6 mmol/L)
9. Achievement of at least PR to induction therapy, without prior progression of disease.
10. Prior completion of standard of care mobilization and collection of stem cells (minimum 2 × 106 CD34+ cells/kg) without use of chemotherapy mobilization, any time prior to or during screening phase.
11. A woman of childbearing potential must have a negative highly sensitive serum pregnancy test at screening and again within 24 hours of the start of study treatment and must agree to further serum or urine pregnancy tests during the study.
12. A woman must be:
a. Not of childbearing potential, or b. Of childbearing potential and practicing true abstinence; or i. Have a sole partner who is vasectomized; or ii. Practicing ≥1 highly-effective, user-independent method of contraception (Appendix B) NOTE: Participant must agree to continue the above throughout the study and for 4 months after the last dose of study treatment. If a woman becomes of childbearing potential after start of the study the woman must comply with point (b) as described above.
13. A woman must agree not to donate eggs (ova, oocytes) or freeze for future use, for the purposes of assisted reproduction during the study and for 4 months after receiving the last dose of study treatment.
14. A man must wear a condom (with or without spermicidal foam/gel/film/cream/suppository) when engaging in any activity that allows for passage of ejaculate to another person during the study and for a minimum of 90 days after receiving the last dose of study treatment. If a female partner is of childbearing potential, she must also be practicing a highly effective method of contraception.
NOTE: If the male participant is vasectomized, he still must wear a condom (with or without spermicidal foam/gel/film/cream/suppository), but his female partner is not required to use contraception.
15. A male participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum of 90 days after receiving the last dose of study treatment.
16. Must be willing and able to adhere to the lifestyle restrictions specified in this protocol.
17. Must sign an Informed Consent Form (ICF) (or their legally acceptable representative must sign) indicating that the participant understands the purpose of, and procedures required for, the study and is willing to participate in the study.
18. All participants must agree to comply with and be enrolled in Revlimid Risk Evaluation and Mitigation Strategy (REMS) program.
19. All participants must agree to comply with and be enrolled in elranatamab Risk Evaluation and Mitigation Strategy (REMS) program.
20. All participants must meet institution-specific criteria for ASCT eligibility as assessed by the Investigator.
Exclusion Criteria:
1. Diagnosis of primary light chain amyloidosis, POEMS, Waldenstrom's macroglobulinemia, plasma cell leukemia, or central nervous system (CNS) involvement by MM.
2. Contraindications or life-threatening allergies, hypersensitivity, or intolerance to any study drug or its excipients (refer to the elranatamab Investigator's Brochure \[IB\] and appropriate package inserts).
3. Prior or concurrent exposure to any of the following:
c. Any anti-BCMA therapy. d. Epigenetic therapy, or treatment with an investigational drug or an invasive investigational medical device within 21 days or ≥5 half-lives, whichever is less.
