Study of the Intra-patient Variability of the Quantitative Parameters of Tumor Perfusion Evaluated With Ultrasound Contrast

RECIST criteria for evaluating tumor response are often inadequate for the evaluation of anti-angiogenic drugs. An evaluation model of tumor perfusion with contrast-enhanced ultrasonography was developed at Gustave Roussy. It assesses the tumor vascular response through the analysis of 7 different parameters. Several studies (four at IGR, involving 117 patients, and a multicenter study involving 400 patients) showed that CEUS allows early evaluation of the effect of anti-angiogenic drugs. Two of these parameters are particularly interesting for the early identification of patients responding (or not) to treatment. Those are area under curve , and area under the wash-out. To further validate the use of these parameters, it is essential to measure and describe the level of their intra-patient variability.

KQB198 in Combination With Imatinib in Participants With Advanced/Metastatic GIST in 1st Line Setting (SynerGIST-1st Line)

This study will test an experimental drug called KQB198 in combination with imatinib. The goal is to determine if this combination is safe and tolerable and assess how effective the combination is at treating GIST. Imatinib has been approved by the FDA for the treatment of different types of cancer including GIST.
