Summary

The purpose of this study is to investigate if an investigational drug called AT13387 is active against Gastrointestinal Stromal Tumor (GIST) that is resistant to other treatments, and to understand more about the safety of AT13387.

Most subjects in the study will receive AT13387 along with another drug called imatinib (Gleevec). Imatinib is a standard (approved) drug for treating patients with GIST. Some patients may receive AT13387 on its own. As a result, we shall begin to understand the effects of AT13387 given on its own and when combined with imatinib.We shall also find out more about the side-effects of AT13387, and more about how the body breaks down (metabolizes) AT13387.

Conditions

  • Gastrointestinal Stromal Tumor (GIST)

Interventions

DRUG

AT13387 and Imatinib

In part 1 pts will receive AT13387 in combination with imatinib. Up to 5 possible dose levels of AT13387 could be evaluated in combination with imatinib 400 mg daily: 120 mg/m2, 150 mg/m2, 180 mg/m2, 220 mg/m2 and 260 mg/m2. AT13387 IV (in the vein) on day 1, 8 and 15 of each 28 day cycle, until progression or unacceptable toxicity develops, in order to establish the recommended phase II combination dose, which will be used in part 2 and/or part 3 of the study. In part 2 an additional 6-9pts will be treated. In part 3, provided that sufficient evidence of anti-tumour effect was observed in part 2 (disease stabilisation or reduction in tumour dimensions by RECIST), then an additional 12pts will be treated with AT13387 in combination with imatinib. Alternatively, if combination treatment is found to have excellent efficacy the randomised phase of the study may start so that 12 pts receive AT13387 on its own (monotherapy) and 12 pts receive AT13387 in combination with imatinib.
