A Study to Learn About a Medicine (Called Elranatamab) in People With Relapsed Refractory Multiple Myeloma

November 3, 2026 updated by: Pfizer

Comparative Effectiveness of Elranatamab Monotherapy in the MagnetisMM-5 Clinical Trial Versus a Real-World External Control Arm of Patients With Relapsed/Refractory Multiple Myeloma With Prior Treatment of Lenalidomide and Proteasome Inhibitor From the Therapy Monitor Multiple Myeloma Dataset in Germany (BasecaMMp)

This study is to understand how well elranatamab (PF-06863135) may be used for relapsed refractory multiple myeloma (RRMM). Sometimes MM might improve at first, but then gets resistant to the treatment and starts growing again (known as relapsed refractory). This study medicine will be compared with standard-of-care (SOC) therapies used in real-world clinical practice. For people receiving elranatamab, we will use data from the phase 3 clinical trial (MagnetisMM-5). We will also use data from a real-world database, representing the SOC in clinical practice. This study does not seek any participants for enrollment. We will compare the experiences of people receiving elranatamab to people receiving SOC therapies. This way, it will help us to know how well elranatamab can be used for RRMM treatment.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients treated with elranatamab will come from the MagnetisMM-5 trial. Patients treated with the standard-of-care therapies will come from electronic health record databases in Germany.

Description

To maximize comparability, the eligibility criteria for the participants from MagnetisMM-5 trial will be applied to patients from the RWD source, as feasible.

Inclusion Criteria:

  • Male or Female aged 18 years and older at index date
  • Diagnosis of MM
  • Measurable disease according to IMWG criteria
  • Prior anti-MM therapy (1-3 prior lines of therapy)
  • ECOG performance status ≤2

Exclusion Criteria:

  • Acute plasma cell leukemia
  • Amyloidosis
  • Smoldering MM
  • Stem cell transplant within 12 weeks of index or active graft versus host disease (GVHD)
  • Ongoing Grade 2 or higher peripheral sensory or motor neuropathy.
  • Active systemic infection or SARS-CoV-2 viral infection
  • Active malignancy within 3 years before index, except for basal cell or squamous cell skin cancer or carcinoma in situ
  • Other surgical, medical, or psychiatric conditions including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study
  • Previous treatment with a BCMA-directed therapy or a CD3-redirecting therapy.
  • Anti-CD38-directed therapy within 6 months preceding the first dose of treatment in this study
  • Refractory to prior anti-CD38-directed therapy (disease progression while on or within 60 days of the last dose of any anti-CD38-directed therapy or failure to achieve at least MR).
  • Previous pomalidomide therapy
  • Administration with an investigational drug within 30 days prior to index
  • For women of childbearing potential: Pregnancy test positive at screening
