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.

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.

Summary

This study tests a drug called teclistamab in people with multiple myeloma that has come back or stopped responding to treatment. The drug is a special antibody that helps the body's immune cells find and attack cancer cells. About 194 participants will receive the drug to see how well it shrinks tumors and how long the effect lasts.

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 bispecific antibody that helps immune cells attack myeloma cells)
What this could lead to
If successful, this could offer a new treatment option for people with multiple myeloma that has stopped responding to other therapies.
What could go wrong
This is an early-phase trial with a small number of participants. The drug may not work for everyone, and side effects like immune reactions are possible.
