Trial Outcomes & Findings for Efficacy and Safety of Dovitinib in Patients With Gastrointestinal Stromal Tumors Refractory and/or Intolerant to Imatinib (NCT NCT01478373)

NCT ID: NCT01478373

Last Updated: 2016-04-27

Results Overview

DCR is defined as the proportion of patients with a best overall response of Complete Responses (CR), Partial Response (PR) and Stable Disease (SD) at 12 weeks according to RECIST (version 1.1). Complete Response (CR): Disappearance of all non-nodal target lesions. In addition, any pathological lymph nodes assigned as target lesions must have a reduction in short axis to \< 10 mm 1;Partial Response (PR): At least a 30% decrease in the sum of diameter of all target lesions, taking as reference the baseline sum of diameters. Progressive Disease (PD): At least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm2. Stable Disease (SD): Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which would qualify for PD.

Timeframe: 9 months

Population: Full Analysis Set: All subjects with histologically confirmed diagnosis of GIST who received at least one dose of study drug.

The PFS duration: time from entry into the study to the date of the first documented progression (assessed using conventional RECIST (version 1.1) or death due to any cause. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
