VOYAGER: Avapritinib vs. regorafenib in unresectable or metastatic GIST


Trial name: Voyager
Agents: Avapritinib (formerly BLU-285) vs. regorafenib
Phase III
Status  Active, not recruiting
Sponsor Blueprint Medicines Corporation


A Phase 3 study in patients with locally advanced unresectable or metastatic GIST (advanced GIST) of avapritinib versus regorafenib in patients previously treated with imatinib and 1 or 2 other tyrosine kinase inhibitors (TKIs).

Further information:


WHO is the trial for?

  • Adult patients with confirmed diagnosis of unresectable or metastatic GIST
  • Patients with a GIST tumour that has progressed or responded inadequately, or who experienced intolerance to previous therapy. Patients should have received imatinib and 1 or 2 other tyrosine kinase inhibitors (TKIs, including adjuvant therapy) before entering this study, but no more than 3 therapies.
  • Overall health status of the patient has to be good (ECOG performance status 0-2)

WHAT is the key question that this trial is attempting to answer?

This study assesses the efficacy of avapritinib compared to regorafenib in patients with advanced or metastatic GIST. It also evaluates the quality of life of patients in both therapy groups.

WHY patients might want to participate?

This clinical trial offers patients an opportunity to access a new therapy strategy. This trial will further support the research in GIST and potentially help other patients with this disease. Patients who may progress on regorafenib can cross-over to the avapritinib arm and patients who might progress on avapritinib, but still benefit from it, may continue on avapritinib.

The trial might or might not have benefit in your individual case.

STUDY DESIGN: What does the study look like?

There are 2 study arms (groups): all participating patients will be randomly divided (by a computer) in two groups. One group will be assigned to avapritinib, the other group will receive regorafenib.

Patients on regorafenib whose disease is progressing (confirmed by central laboratory) may crossover to avapritinib.
