NCT ID NCT05932680

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

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 looks at whether people with multiple myeloma who have responded very well to teclistamab can safely stop taking it for a while. Instead of staying on the drug indefinitely, participants who have had a good response for 6-9 months will pause treatment and be closely monitored. If the cancer shows signs of returning, they will restart teclistamab. The goal is to see if this drug holiday works as well as continuous therapy, while reducing side effects like infections and the risk of the cancer becoming resistant.

What this could mean

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

Active substance
teclistamab
What this could lead to
If successful, this could allow some multiple myeloma patients to take a break from teclistamab without the cancer returning quickly, reducing infections and drug resistance.
What could go wrong
This is a small, early-phase study (75 people) without a comparison group. The cancer may return sooner than expected, and not all patients will benefit from stopping therapy.

Inclusion Criteria: * Participants must be age ≥18 and able to give written, informed consent. * Participants must have initiated teclistamab (first full dose) 6-9 months prior to enrollment and received an average teclistamab dose of at least 1.5 mg/kg/month since the date of the first 1.5 mg/kg dose. * Participants must have received a teclistamab dose within 4 weeks prior to enrollment. * Participants must have had measurable disease according to IMWG criteria within 1 month prior to teclistamab initiation or first full teclistamab dose * Participants must have achieved a confirmed VGPR or better to teclistamab therapy at any assessment prior to enrollment and have ongoing response (i.e., no disease progression) at time of enrollment per IMWG consensus criteria (Appendix 14.3). * Prior to initiating teclistamab, participants must have received therapy with a proteasome inhibitor, thalidomide analog (lenalidomide or pomalidomide), and an anti-CD38 antibody and meet one of the following criteria: 1. ≥3 prior lines of therapy (with lines-of-therapy delineated according to IWMG guidelines) 2. Refractory to both a proteasome inhibitor and a thalidomide analog. * Participants must have had an ECOG performance status of 0-2 at time of teclistamab initiation; in addition, ECOG performance status must be 0-1 at time of enrollment. * Participants must not have known diagnoses of systemic amyloidosis or POEMS syndrome.
