Phase 3 Study of Teclistamab in Combination With Lenalidomide and Teclistamab Alone Versus Lenalidomide Alone in Participants With Newly Diagnosed Multiple Myeloma as Maintenance Therapy Following Autologous Stem Cell Transplantation
(MajesTEC-4)
What this study is about
This is a conducted at multiple hospitals, randomly assigned, where both patients and doctors know the treatment given, Phase 3 study in participants with newly diagnosed multiple myeloma to evaluate the benefits of teclistamab in combination with lenalidomide and teclistamab alone versus lenalidomide alone as maintenance therapy after autologous stem cell transplant.
View original scientific description
This is a multicenter, randomized, open-label, Phase 3 study in participants with newly diagnosed multiple myeloma to evaluate the benefits of teclistamab in combination with lenalidomide and teclistamab alone versus lenalidomide alone as maintenance therapy after autologous stem cell transplant.
Interventions
DRUG
Teclistamab
Teclistamab will be administered via a subcutaneous injection (SC)
DRUG
Lenalidomide
Lenalidomide will be administered orally
Primary outcome measures
Progression Free Survival (PFS)
Time frame: from randomization to the date of disease progression or death (approximately up to 8 years)
PFS is defined as the time from the date of randomization to the date of disease progression (as assessed by IMWG criteria) or death due to any cause, whichever occurs first.
Minimal Residual Disease (MRD)-negative Complete Response (CR)
Time frame: at month 12
12-month MRD-negative CR is defined as participants who achieve MRD-negative status at 12 months, as determined by next-generation flow cytometry (NGF) with sensitivity of 10\^-5, prior to progressive disease or subsequent anti-myeloma therapy, whichever is earlier, and who also achieve CR of better, according to IMWG criteria.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Must have a new diagnosis of multiple myeloma according to IMWG criteria and have received induction +/- consolidation.
- Must have received only one line of therapy and achieved at least a partial response (≥PR) as per IMWG 2016 response criteria (Kumar 2016) without evidence of progression at the time of first treatment dose.
- Must not be intolerant to the starting dose of lenalidomide.
- Must not have received any maintenance therapy.
- Have an ECOG performance status score of 0, 1, or 2 at screening and immediately prior to the start of administration of study treatment
- Have clinical laboratory values within prespecified range.
Exclusion criteria
- Received any prior BCMA-directed therapy.
- Any previous therapy with an immune cell redirecting agent or gene modified adoptive cell therapy (eg, chimeric antigen receptor modified T cells, NK cells).
- Discontinued treatment due to any AE related to lenalidomide as determined by the investigator.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
