NCT ID NCT06425991

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Summary

This study compares two versions of the drug teclistamab—one made with the current process and one with a new process—in 108 people with multiple myeloma that has come back or not responded to treatment. The main goal is to see if the body absorbs and handles both versions the same way. Participants receive the drug as a shot under the skin, and researchers will also monitor immune responses and tumor shrinkage.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Teclistamab (a drug given as a shot under the skin)
What this could lead to
If successful, this study could confirm that the new manufacturing process produces teclistamab that works just as well, ensuring a stable supply for patients.
What could go wrong
This is an early-phase study focused on drug levels in the body, not on proving the drug works better. It is small and may not show meaningful differences in how patients feel or their outcomes.

Inclusion Criteria: * Documented diagnosis of multiple myeloma as defined by the criteria below: (a) Multiple myeloma diagnosis according to International Myeloma Working Group (IMWG) diagnostic criteria (b) Measurable disease at screening as defined by any of the following: (1) Serum M-protein level greater than or equal to (\>=) 0.5 grams per deciliter (g/dL) (central laboratory); or (2) Urine M-protein level \>=200 milligrams (mg)/24 hours (central laboratory); or (3) Serum immunoglobulin free light chain \>=10 milligrams per deciliter (mg/dL) (central laboratory) and abnormal serum immunoglobulin kappa lambda free light chain ratio * Received 1 to 3 prior lines of antimyeloma therapy, including a minimum of 2 consecutive cycles each of a protease inhibitor (PI), lenalidomide, and an anti-cluster of differentiation 38 (CD38) monoclonal antibody (or minimum of 6 doses if anti CD38 monoclonal antibody was only part of a maintenance regimen) in any prior line * Documented evidence of progressive disease or failure to achieve a response to last line of therapy based on investigator's determination of response by IMWG criteria * Have an eastern cooperative oncology group (ECOG) performance status score of 0 to 2 * A female participant of childbearing potential must have a negative highly sensitive serum pregnancy test at screening and within 24 hours of the start of study treatment and must agree to further serum or urine pregnancy tests during the study Exclusion Criteria: * Received any bispecific antibody and/or chimeric antigen receptor T cell (CAR-T) cell therapy * Contraindications or life-threatening allergies, hypersensitivity, or intolerance to any study drug or its excipients * Received a live, attenuated vaccine within 4 weeks before the first dose of study drug. Non-live or non-replicating vaccines authorized for emergency use by local health authorities are allowed * Central nervous system involvement or clinical signs of meningeal involvement of multiple myeloma. If either is suspected, negative whole brain magnetic resonance imaging (MRI) and lumbar cytology may be required * Participant had major surgery or had significant traumatic injury within 2 weeks prior to randomization, or will not have fully recovered from surgery, or has major surgery planned during the time the participant is expected to be treated in the study
