(VOYAGER) Study of Avapritinib vs Regorafenib in Patients With Locally Advanced Unresectable or Metastatic GIST

September 9, 2022 updated by: Blueprint Medicines Corporation

An International, Multicenter, Open-label, Randomized, Phase 3 Study of BLU-285 vs Regorafenib in Patients With Locally Advanced Unresectable or Metastatic Gastrointestinal Stromal Tumor (GIST)

This is an open-label, randomized, Phase 3 study in patients with locally advanced unresectable or metastatic GIST (advanced GIST) of avapritinib (also known as BLU-285) versus regorafenib in patients previously treated with imatinib and 1 or 2 other TKIs.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Efficacy of Avapritinib Based on Progression-free Survival (PFS) Determined by Central Radiological Assessment Per Modified Response Evaluation Criteria in Solid Tumors (mRECIST), Version 1.1
Time Frame: 24 Months
To demonstrate the efficacy of avapritinib based on progression-free survival (PFS) determined by central radiological assessment per modified Response Evaluation Criteria in Solid Tumors (mRECIST), version 1.1 in patients with advanced GIST following 2 or 3 regimens of prior treatment with a tyrosine kinase inhibitor (TKI), including imatinib, compared to patients treated with regorafenib. A progressively growing tumor must meet the following criteria: a) the target lesions must be greater or equal to 2cm in size and be a new GIST active lesion or b) the target lesions must be expanding on at least 2 sequential imaging studies.
24 Months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Objective Response Rate (ORR) Determined by Central Radiology Assessment Per mRECIST, Version 1.1
Time Frame: 24 Months
To evaluate objective response rate (ORR) determined by central radiology assessment per mRECIST, version 1.1 in patients with advanced GIST treated with avapritinib compared to patients treated with regorafenib. A complete response (CR) per modified Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) is defined as complete disappearance of all target lesions. A partial response (PR) is defined as at least 30% decrease in the sum of diameters of target lesions taking as reference the baseline sum of diameters. Overall Response (OR) = CR + PR
24 Months
Overall Survival (OS) in Patients With Advanced GIST Treated With Avapritinib Compared to Patients Treated With Regorafenib
Time Frame: 24 Months
To evaluate overall survival (OS) in patients with advanced GIST treated with avapritinib compared to patients treated with regorafenib
24 Months
European Organisation for Research and Treatment of Cancer Quality of Life (EORTC-QLQ-30). Change in Individual Scores in Patients With Advanced GIST Treated With Avapritinib Compared to Patients Treated With Regorafenib
Time Frame: Difference between baseline and week 12 of treatment
The Global Health Status Score is derived from question 29 and 30 on the EORTC-QLQ-C30 tool. The change in score was assessed between baseline and week 12 in patients treated with advanced GIST treated with avapritinib compared to patients treated with regorafenib. The Global Health Status Score score range is 0 to 100 with a higher score indicating better global health status. A positive change indicates improvement in global health status.
Difference between baseline and week 12 of treatment
