NCT ID NCT07313943

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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 study looks at rare lymphomas that are hard to tell apart under the microscope—some look like Hodgkin lymphoma but lack a key marker (PAX5), making them similar to another type called anaplastic large cell lymphoma (ALCL). Researchers will analyze tissue samples from 60 adults to find genetic and protein patterns that can better distinguish these two diseases. The goal is to improve diagnosis, since the two types have very different survival rates and treatments.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with lymphoma diagnosed as classic Hodgkin's lymphoma with a negative PAX5 marker * Patients with uncertain differential diagnosis between classical Hodgkin's lymphoma with atypical phenotype (PAX5 negative) and ALK-negative anaplastic large T-cell lymphoma (PAX5 negative) * Adult males and females at diagnosis * Availability of the molecular and/or cytogenetic data. Exclusion Criteria: * Patients with a diagnosis other than that under study, for whom clinical/histological/molecular information is not available
