Paused for now. It may or may not start again.
Ongoing This study
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 Results may not be published yet.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

Summary

This study compares two drugs, ripretinib and sunitinib, in people with advanced gastrointestinal stromal tumors (GIST) that have specific genetic changes (KIT exon 11 plus 17/18 mutations) and have stopped responding to the first treatment, imatinib. About 54 participants will be randomly assigned to receive either ripretinib or sunitinib to see which one better delays cancer growth. If the cancer worsens on sunitinib, those patients may switch to ripretinib.

What this could mean

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

Active substance
Ripretinib (QINLOCK) and Sunitinib (Sutent)
What this could lead to
If ripretinib works better than sunitinib, it could become a new standard second-line treatment for people with this specific type of advanced GIST.
What could go wrong
This is a relatively small Phase 3 trial (54 participants) and results may not apply to all GIST patients. There is no guarantee ripretinib will prove superior or be approved for this use.
