Prostate Cancer
Conditions
Brief summary
This is a multicenter phase 2 open-label single-arm study that will evaluate the safety and efficacy of TAK-700 in patients with castration-resistant prostate cancer (CRPC) without radiographic evidence of metastases who have a rising prostate-specific antigen (PSA).
Interventions
TAK-700 will be administered orally (PO) twice daily (BID) on a continuous schedule

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To determine the percentage of patients who achieve a PSA less than or equal to 0.2 ng/mL following 3 months of TAK-700 treatment | 3 months |
Secondary
| Measure | Time frame |
|---|---|
| To determine PSA response rate (PSA decline of at least 90%, 50% and 30% from baseline)at 3 and 6 months | 3 and 6 months |
| To determine the percentage of patients who achieve a PSA less than or equal to 0.2 ng/mL following 6 months of TAK-700 treatment | 6 months |
| To determine time to PSA progression, time to metastases, and duration of progression-free survival | Evidence of PSA or disease progression |
| To monitor changes in endocrine markers | Evidence of PSA or disease progression |
| To evaluate the safety of TAK-700 | Evidence of PSA or disease progression |
