A Phase III Study of Elranatamab Versus Lenalidomide in Patients with Newly Diagnosed Multiple Myeloma After Transplantation
Zusammenfassung der Studie
The aim of the study is to assess whether elranatamab monotherapy compared to lenalidomide monotherapy (control) can provide clinical benefit to patients with newly diagnosed multiple myeloma following autologous stem cell transplantation. A total of approximately 760 patients will be enrolled in the study. The primary endpoint is to compare progression-free survival for elranatamab (arm C) and lenalidomide (arm B) by BICR (central assessment) according to the International Myeloma Working Group (IMWG) for concurrently randomized patients. All participants are expected to receive the study intervention until confirmed disease progression, withdrawal of consent, lost to follow-up, unacceptable toxicity, or study termination. After discontinuation of the study intervention, participants will be followed until withdrawal of consent, lost to follow-up, death, or the defined study end date. followed for survival. The use of elranatamab monotherapy as maintenance is supported by the efficacy results from the Phase I study. Lenalidomide was chosen as the comparator in this study because it is considered the standard of care and the only approved agent in this setting, with its benefit demonstrated in several published studies.

Untersuchte Intervention
For the purposes of this protocol, the study intervention refers to elranatamab and lenalidomide.
Elranatamab
Elranatamab is a drug that consists of two antibodies . Elranatamab binds to T cells (a type of immune system cell) and myeloma cells; this causes the T cells to kill the myeloma cells.
Elranatamab is given to participants as a subcutaneous injection by qualified and trained staff at the investigator's site.
Lenalidomide
Lenalidomide is an immune-modulating drug that targets and kills myeloma cells. It helps the immune system recognize and destroy myeloma cells and prevents the growth of new myeloma cells by removing them from the bloodstream.
Participants will be instructed to swallow the study intervention whole and not to chew the capsule before swallowing.
Participants will be randomly assigned in a 1:1 ratio to receive either elranatamab (Arm C) or Lenalidomide (Arm B). The 1:1 ratio means there is a 50% chance of receiving elranatamab or a 50% chance of receiving lenalidomide.

Participation in the study is only possible if all of the following criteria apply Age and gender: 1. Participants aged ≥ 18 years at Visit 1 (screening) or, if applicable, at the pre-screening visit. Type of participants and disease characteristics: 2. Participants who are willing and able to adhere to the scheduled visits, treatment plan, laboratory tests, lifestyle instructions and other study procedures. 3. Multiple myeloma diagnosis as defined by IMWG (International Myeloma Working Group) criteria with measurable disease at diagnosis. 4. Partial response or better according to IMWG (International Myeloma Working Group) criteria at the time of randomization. 5. Identification of the dominant malignant (index) clone, assessed by NGS testing from the central laboratory. 6. ECOG (Eastern Cooperative Oncology Group) performance status ≤ 1. 7. Left ventricular ejection fraction (LVEF) ≥ 40%, determined by multigated acquisition (MUGA) scan or echocardiogram (ECHO). 8. Adequate liver function. 9. Adequate renal function. 10. Adequate recovery of bone marrow function at screening and at randomization after autologous stem cell transplantation. 11. Corrected serum calcium ≤ 14 mg/dL. 12. Resolved acute effects of prior therapy on severity at baseline or CTCAE grade ≤ 1 (CTCAE – common terminology criteria for adverse events). Patient information and consent form: 13. All participants must be able to sign a patient information and consent form as described in Appendix 1. (BASEC)
Ausschlusskriterien
Participants will be excluded from the study if one or more of the following criteria apply: Diseases: 1. Plasma cell leukemia. 2. Amyloidosis, Waldenström macroglobulinemia, or POEMS syndrome. 3. Known active CNS involvement or clinical signs of myelomatous meningeal involvement 4. Impaired cardiovascular function or clinically significant cardiovascular disease. 5. Persistent Grade ≥ 3 peripheral sensory or motor neuropathy. 6. History of Guillain-Barré syndrome (GBS) or GBS variants or history of Grade ≥ 3 peripheral motor polyneuropathy. 7. Live attenuated vaccine within 4 weeks prior to first dose. 8. Known or suspected hypersensitivity to the study intervention or any of its excipients. 9. Any other active malignancy within three years prior to enrollment, with the exception of an adequately treated basal cell or squamous cell carcinoma of the skin or carcinoma in situ, or stage 0/1 with minimal risk of recurrence as judged by the investigator. 10. Other surgical (including major surgery within 14 days prior to enrollment), medical or psychiatric conditions, including recent (within the past year) or active suicidal ideation or behavior, or laboratory abnormalities that may increase the risk of study participation or, in the opinion of the investigator, make the patient unsuitable for the study. Previous/concomitant therapy: 11. Previous MM maintenance therapy. 12. Previous treatment with BCMA (B-cell maturation antigen)-targeted therapy. Experience from previous/concomitant clinical trials: 13. Previous administration of an investigational medicinal product or vaccine within 30 days. Diagnostic assessments: 14. Positive (BASEC)
