NCT ID NCT01794572

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
The trial has finished. Results may not be published yet.
Stopped early This study
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 early-phase study tested a combination of high-dose chemotherapy (melphalan) and escalating doses of total bone marrow irradiation, followed by a stem cell rescue, in 13 people with multiple myeloma that had returned after initial treatment. The goal was to find the highest safe radiation dose. The trial was terminated early, so results are limited.

What this could mean

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

Active substance
Total bone marrow irradiation and melphalan chemotherapy
What this could lead to
If successful, this approach could offer a more targeted way to deliver high-dose therapy before a stem cell transplant for relapsed multiple myeloma.
What could go wrong
This was a very early, small trial that was terminated before completion. The combination of high-dose radiation and chemotherapy carries significant risks, including severe side effects.
