简要总结

This pilot clinical trial studies cabozantinib-s-malate in treating patients with hormone-resistant metastatic prostate cancer. Cabozantinib-s-malate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth

详细描述

PRIMARY OBJECTIVES:

I. To evaluate the timing, pathophysiology, and magnitude of changes in tumor imaging and pharmacodynamic markers with XL184 (cabozantinib-s-malate) treatment in metastatic castrate resistant prostate cancer.

SECONDARY OBJECTIVES:

I. To estimate the progression-free survival (PFS) achieved with XL184 in metastatic castrate resistant prostate cancer (CRPC) patients.

II. To evaluate the feasibility of the therapy, and the toxicities associated. III. To evaluate overall survival (OS) in metastatic CRPC patients post androgen deprivation therapy (ADT) treated with XL-184.

•Serum albumin >= 2.8 g/dl
•Serum creatinine =< 1.5 x ULN or creatinine clearance (CrCl) >= 50 mL/min; for creatinine clearance estimation, the Cockcroft and Gault equation should be used
•Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN if no liver involvement, or =< 5 x ULN with liver involvement
•Lipase < 1.5 x the upper limit of normal (except for subjects with adenocarcinoma of the pancreas)
•Urine protein/creatinine ratio (UPCR) =< 1

•The subject is capable of understanding and complying with the protocol requirements and has signed the informed consent document
•Patients participating in this trial must also be eligible and willing to sign consent for participation in [2'-18F]-1-(2'-deoxy-2'-fluoro-beta-D-arabinofuranosyl)thymine (FMAU) and 18F-flouride positron emission tomography (PET) scans done under separate protocols
•Sexually active subjects (men) must agree to use medically accepted barrier methods of contraception (eg, male condom, or diaphragm with spermicidal gel) during the course of the study and for 4 months after the last dose of study drug(s), even if oral contraceptives are also used by the female partner; all subjects of reproductive potential must agree to use both a barrier method and a second method of birth control
•Projected life expectancy of at least 6 months
•No prior history of other malignancies in the last 3 years, except for squamous and basal cell skin cancer

排除标准

•The subject has received cytotoxic chemotherapy (including investigational cytotoxic chemotherapy) or biologic agents (eg, cytokines or antibodies) within 3 weeks, or nitrosoureas/mitomycin C within 6 weeks before the first dose of study treatment
•Prior treatment with cabozantinib
•The subject has received radiation therapy:
•To the thoracic cavity or gastrointestinal tract within 3 months of the first dose of study treatment
•To bone or brain metastasis within 14 days of the first dose of study treatment
•To any other site(s) within 28 days of the first dose of study treatment
•The subject has received radionuclide treatment within 6 weeks of the first dose of study treatment
•The subject has received prior treatment with a small molecule kinase inhibitor or a hormonal therapy (including investigational kinase inhibitors or hormones) within 14 days or five half-lives of the compound or active metabolites, whichever is longer, before the first dose of study treatment; patients receiving LHRH or gonadotropin-releasing hormone (GnRH) agonists to maintain castrate levels of testosterone or patients on bisphosphonate/denosumab, may be maintained on these agents
