A Study of Famitinib in Patients With Gastrointestinal Stromal Tumor

Phase 2

• Conditions: Gastrointestinal Stromal Tumor
• Interventions: Drug: Famitinib

• Registration Number: NCT02336724
• Lead Sponsor: Jiangsu HengRui Medicine Co., Ltd.

Brief Summary

Famitinib is a tyrosin-inhibitor agent targeting at c-Kit, VEGFR2, PDGFR, VEGFR3, Flt1 and Flt3. Phase I study has shown that the toxicity is manageable.

The purpose of this study is to evaluate the efficacy and safety profile of Famitinib in patients with advanced or metastatic gastrointestinal stromal tumor who failed from imatinib therapy.

• Have surgery or radiotherapy within 4 weeks or have temporary radiotherapy for palliative treatment within 2 weeks
• A variety of factors that affect the oral medication (such as inability to swallow, gastrointestinal resection, chronic diarrhea and intestinal obstruction)
• Other cancer diagnosed within past 5 years or currently suffering , but other than cure basal cell carcinoma and cervical carcinoma in situ
• Within 12 months before the first treatment occurs artery / venous thromboembolic events, such as cerebral vascular accident (including transient ischemic attack), deep vein thrombosis and pulmonary embolism, etc

• Child bearing or pregnancy female. Potential child bearing female must have a negative urine or serum pregnancy test result before initiating.
• All subjects who are not surgically sterile or postmenopausal must agree and commit to the use of a reliable method of birth control for the duration of the study and for 6 months after the last dose of test drug.
• Evidence of significant medical illness that in the investigator's judgment will substantially increase the risk associated with the subject's participation in and completion of the study.
