Brief Summary:
This is a 2-arm, randomized, placebo-controlled, double-blind, international, multicenter study comparing the efficacy of ripretinib (DCC-2618) to placebo in patients who have received treatment with prior anticancer therapies. Prior anticancer therapies must include imatinib, sunitinib, and regorafenib (3 prior therapies). Approximately 120 patients were randomized in a 2:1 ratio to ripretinib 150 mg QD or placebo

Primary Outcome Measures :
- Progression-Free Survival (PFS) [ Time Frame: From date of randomization to the earliest date of disease progression or death from any cause [through database cutoff 31-May-2019 (up to approximately 15 months)]. ]PFS was defined as the time interval between the date of randomization and the earliest documented evidence of the first disease progression based on the independent radiologic review or death due to any cause on initially assigned study treatment, whichever comes earlier, assessed at 26, 39, and 52 weeks.
Secondary Outcome Measures :
- Objective Response Rate (ORR) [ Time Frame: From date of randomization to the earliest date of disease progression or death from any cause [through database cutoff 31-May-2019 (up to approximately 15 months)]. ]The percentage of patients with a confirmed complete response or PR (CR: Disappearance of all target lesions and non-target lesions (if present at baseline); all lymph nodes must be non-pathological in size) or partial response (PR: >=30% decrease in the Sum of Diameters of target lesions and non-target lesions non-PD or NE or none at baseline; or target lesions CR and non-target lesions non-CR/Non-PD or NE) based on the independent radiologic review and during the initially assigned study treatment. To be assigned a status of a CR or PR, changes in tumor measurements must be confirmed by repeat CT or MRI assessments that must be performed at least 4 weeks after the criteria for response are first met.
- Time to Tumor Progression (TTP) Based on Independent Radiologic Review [ Time Frame: From date of randomization to the earliest date of disease progression [through database cutoff 31-May-2019 (up to approximately 15 months)]. ]TTP is defined as the interval between the date of randomization and the earliest documented evidence of disease progression based on the independent radiologic review.
- Overall Survival (OS) [ Time Frame: From the date of randomization to the date of death from any cause [through database cutoff 31-May-2019 (up to approximately 15 months)]. ]Overall Survival (OS) was defined as the interval between the date of randomization until the date of death or the date of last follow-up.
- Quality of Life & Disease-Related Symptoms - European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer 30-Item - Role Functioning [ Time Frame: From the date of randomization (Baseline) to Cycle 2 Day 1 (Month 2) ]Changes from baseline in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer 30-item - Role Functioning. For the ripretinib arm the minimum and maximum for the outcome were -67 to 67; the placebo arm had a range of -83 to 67. The higher value represents a higher quality of life in disease-related symptoms.
- Quality of Life & Disease-Related Symptoms - Physical Functioning [ Time Frame: From the date of randomization (Baseline) to Cycle 2 Day 1 (Month 2) ]Changes from baseline in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire for Cancer 30-Item - Physical Functioning. For the ripretinib arm, the minimum and maximum for the outcome were -33 to 53; the placebo arm had a range of -47 to 20. The higher value represents a higher quality of life in disease-related symptoms.
- Quality of Life & Disease-Related Symptoms - EuroQol Visual Analogue Scale [ Time Frame: From the date of randomization (Baseline) to Cycle 2 Day 1 (Month 2) ]Change from baseline in EuroQol Visual Analogue Scale. For the ripretinib arm the minimum and maximum for the outcome were -43 to 91; the placebo arm had a range of -68 to 23. The higher value represents a higher quality of life in disease-related symptoms.

Criteria
Inclusion Criteria:
- Histologic diagnosis of GIST
- Patients must have progressed on imatinib, sunitinib, and regorafenib or have documented intolerance to any of these treatments.
- ECOG PS of 0 to 2 at screening.
- Able to provide an archival tumor tissue sample if no anticancer therapy was administered since the sample was collected; otherwise, a fresh tumor tissue sample is required prior to the first dose of study drug.
- Female patients of childbearing potential must have a negative serum beta-human chorionic gonadotrophin (β-hCG) pregnancy test at screening and negative urine pregnancy test at Cycle 1 Day 1 prior to the first dose of study drug.
- Patients of reproductive potential must agree to follow the contraception requirements.
- The patient is capable of understanding and complying with the protocol and has signed the informed consent document. A signed informed consent form must be obtained before any study-specific procedures are performed.
- At least 1 measurable lesion according to modified RECIST Version 1.1 (non-nodal lesions must be ≥1.0 cm in the long axis or ≥double the slide thickness in the long axis) within 21 days prior to the first dose of study drug.
-
Adequate organ function and bone marrow reserve as indicated by the following laboratory assessments performed at screening.
- Absolute neutrophil count ≥1000/uL
- Hemoglobin ≥8 g/dL
- Platelet count ≥75,000/uL
- Total bilirubin ≤1.5 x the upper limit of normal (ULN)
- Aspartate transaminase or alanine transaminase ≤3 x ULN (≤5x ULN in the presence of hepatic metastases)
- Serum creatinine ≤1.5 x ULN or creatinine clearance ≥50 mL/min based on either urine collection or Cockcroft Gault estimation.

Patients on a stable, maintenance regimen of anticoagulant therapy for at least 30 days prior to study drug administration may have PT/INR measurements >1.5 x ULN if, in the opinion of the Investigator, the patient is suitable for the study. An adequate rationale must be provided to the Sponsor prior to randomization.
