This trial is active, not recruiting.
|Conditions||prostatic neoplasms, prostate cancer|
|Treatments||tak-700, fluorine f 18 sodium fluoride, positron emission tomography, computed tomography|
|Sponsor||University of Wisconsin, Madison|
|Collaborator||Millennium Pharmaceuticals, Inc.|
|Start date||May 2013|
|End date||December 2015|
|Trial size||8 participants|
|Trial identifier||NCT01816048, CO12810|
The purpose of this study is to assess whether NaF PET/CT scans can be used to evaluate treatment response in bone metastases in subjects with prostate cancer treated with the investigational drug, TAK-700.
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
To measure changes in NaF PET/CT standardized uptake values (SUVmean and SUV max) from prior to dosing with Tak-700 to 4-8 weeks after starting treatment with TAK-700
time frame: baseline to month 3
Measure prostate specific antigen (PSA) response rate in patients treated with TAK700, as measured by a decline in the PSA level from baseline to the month 3 assessment according to the Prostate Cancer Clinical Trials Working Group (PCWG2)
time frame: baseline to month 3
Number of subjects who experience adverse events while on treatment with TAK 700
time frame: Approximately 12 months
Measure change in PSA kinetics with TAK700 from baseline to off treatment
time frame: baseline and off treatment
Measure changes in NaF PET/CT results in response to TAK700
time frame: baseline and 8 weeks
Compare changes on NaF PET/CT after treatment with TAK700 with standard clinical outcomes including PSA doubling time, response evaluation criteria in solid tumors (RECIST), and radiographic progression free survival.
time frame: Approximately 24 months
To document the change in the number of circulating tumor cells using one or more methods -includes PSA Elispot, flow cytometry and the VeriFAST platform
time frame: baseline, one month, 3 months and at off study visit
To document change in the number of circulating tumor cells using the cell search system (Veridex, LLC) obtained prior to beginning treatment with TAK 700, after completing one cycle and after completing 3 cycles.
time frame: baseline, one month and 3 months
To compare PSA response rate and circulating tumor cell counts of subjects receiving TAK700 to NaF PET/CT imaging results
time frame: Baseline, one month, 2 months, 3 months
Male participants at least 18 years old.
