Ovarian Cancer Clinical Trial
Imatinib Mesylate in Combination With Docetaxel for Advanced, Platinum-Refractory Ovarian Cancer
Summary
Imatinib mesylate is an inhibitor of the receptor tyrosine kinases for platelet-derived growth factor (PDGF) and stem cell factor (SCF), c-Kit, and inhibits PDGF- and SCF-mediated cellular events. Docetaxel promotes cell growth arrest by inhibiting the deassembly of tubulin and by promoting at the same time microtubule assembly. Docetaxel has single agent activity in ovarian cancer with response rates of 30-40% in the platinum refractory setting. The combination of imatinib mesylate and docetaxel has potential synergistic effects, based on previous reports showing synergy in-vitro and in-vivo between PDGFR inhibitors or PI3K inhibitors and taxane chemotherapy.
This trial will investigate the efficacy the combination of imatinib mesylate and docetaxel in treating patients with advanced, platinum-refractory ovarian cancer and primary peritoneal carcinomatosis.
Full Description
OUTLINE: This is a multi-center study.
Submit tumor and serum samples for central review
Imatinib 600 mg (orally qd);
Docetaxel 30mg/m2 (4 of 6 weeks);1 cycle = 6 weeks
Evaluate every other cycle
Each cycle will begin only when the granulocyte count is > 1,500/mm3 and the platelet count is > 100,000/mm3 and any other treatment-related toxicities are < grade 1. If the toxicity is not resolved to grade 0 or 1 after three weeks, the patient will be withdrawn from the study. For days 8, 15, and 22 patients must have an absolute neutrophil count > 1,000/mm3 or greater and platelet count > 75,000/mm3. Imatinib mesylate can be administered if platelets >20,000 and ANC >500.

No major surgery within 28 days prior to being registered to protocol therapy.
No refractory ascites requiring drainage more frequently than once a month
No presence of clinically significant small bowel obstruction
No prior exposure to docetaxel (exposure to paclitaxel is allowed)
No parenteral nutrition within 28 days prior to being registered to protocol therapy.
No concomitant treatment with potent CYP 3A4 inhibitors (i.e., ketoconazole) is permitted during therapy on this protocol.
No therapeutic anticoagulation with warfarin while on study (use of low molecular weight heparin is allowed, if necessary).
No peripheral neuropathy > grade 1
No history of severe hypersensitivity reaction to docetaxel or other drugs formulated with polysorbate 80.
No serious concomitant systemic disorders incompatible with the study
No prior malignancies with the exception of curatively treated basal or squamous carcinoma of the skin, carcinoma in-situ of the cervix, or any other cancer for which the patient has been disease-free for < 5 years.
