NCT02508532 · STUDY IN CONTEXT

(NAVIGATOR) Study of BLU-285 in Patients With Gastrointestinal Stromal Tumors (GIST) and Other Relapsed and Refractory Solid Tumors

Draft scope assessment: narrower. Linked by condition-string match at the cancer-entity level. The study's eligibility - stage, biomarker, treatment line and prior therapy - has not been reconciled against this page's definition, so its population is narrower than this page in ways not yet recorded. The condition was transformed or resolved through the terminology hierarchy to reach this cancer type, so the link itself is a candidate a reviewer must confirm. Found because this study's registry identifier is printed in an FDA approval notice, an FDA product label or an NCI summary held by this site. The citing document and the exact position of the identifier inside it are recorded. Being cited is not a statement that the study supports this treatment.

primary · POSTED

The overall safety profile of the drug was assessed by reviewing the number of patients with AEs, SAEs and other events. There was no formal statistical analysis. Safety assessments continued for the duration of treatment.

primary · POSTED

To evaluate objective response rate (ORR) determined by central radiology assessment per mRECIST, version 1.1 in patients with advanced GIST treated with avapritinib. A complete response per modified Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) is defined as complete disappearance of all target lesions. A partial response 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
