NCT ID NCT03902184

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
Running, but no longer taking on new participants.
Completed This study
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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This phase 2 trial tested a drug called lacutamab (IPH4102) in 170 people with advanced T-cell lymphoma, including Sezary syndrome and mycosis fungoides. The drug is an antibody that targets a protein on cancer cells. It was given alone or with chemotherapy to see if it could shrink tumors and improve quality of life. The study is now complete, and results will show how safe and effective the treatment is.

What this could mean

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

Active substance
lacutamab (IPH4102), a targeted antibody
What this could lead to
If successful, this could provide a new treatment option for people with advanced T-cell lymphoma who have not responded to other therapies.
What could go wrong
This is a phase 2 trial, so results are still early. The drug may not work for all patients, and side effects are possible. Further studies are needed before it becomes widely available.
