Study of Cabozantinib (XL184) Versus Prednisone in Men With Metastatic Castration-resistant Prostate Cancer Previously Treated With Docetaxel and Abiraterone or MDV3100 (COMET-1)
This study is ongoing, but not recruiting participants.

This study will evaluate the effect of cabozantinib compared to prednisone on overall survival in men with previously treated metastatic castration-resistant prostate cancer with bone-dominant disease who have experienced disease progression on docetaxel-containing chemotherapy and abiraterone or MDV3100.
Castration Resistant Prostate Cancer
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
||A Phase 3, Randomized, Double-blind, Controlled Study of Cabozantinib (XL184) Versus Prednisone in Metastatic Castration-resistant Prostate Cancer Patients Who Have Received Prior Docetaxel and Prior Abiraterone or MDV3100
Primary Outcome Measures:
- Overall survival [ Time Frame: Through 21 months after study start ] [ Designated as safety issue: No ]
Secondary Outcome Measures:
| Estimated Enrollment:
| Study Start Date:
| Estimated Primary Completion Date:
||March 2014 (Final data collection date for primary outcome measure)
Subjects randomized to the cabozantinib arm will also receive placebo-matched prednisone capsules.
Tablets taken orally once-daily
Other Name: XL184
Active Comparator: prednisone
Subjects randomized to the prednisone arm will also receive placebo-matched cabozantinib.
Taken twice a day orally. Commercially-obtained prednisone tablets will be over-encapsulated in order to blind identity.

- Evidence of bone metastasis related to prostate cancer on bone scans.
- Received prior docetaxel (minimum cumulative dose of 225 mg/m2) and either abiraterone or MDV3100 treatment and has evidence of prostate cancer progression on each agent independently.

- Adequate organ and marrow function.
- Capable of understanding and complying with the protocol requirements and signed the informed consent form.
- Sexually active fertile patients and their partners must agree to use medically accepted methods of contraception (eg, barrier methods, including male condom, female condom, or diaphragm with spermicidal gel) during the course of the study and for 3 months after the last dose of study treatment.
- Prior treatment with cabozantinib.
- Treatment with docetaxel, abiraterone, or MDV3100 in the last 2 weeks; or with any other type of cytotoxic or investigational anticancer agent in the last 2 weeks.

- Requires concomitant treatment, in therapeutic doses, with anticoagulants antiplatelet agents.
- Requires chronic concomitant treatment of strong CYP3A4 inducers (eg, dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentin, phenobarbital, and St. John's Wort).
- Uncontrolled, significant intercurrent illness including, but not limited to, cardiovascular disorders, gastrointestinal disorders, active infections, non-healing wounds, recent surgery.
- Clinically significant hematemesis or hemoptysis, or other signs indicative of pulmonary hemorrhage in the last 3 months, or history of other significant bleeding in the past 6 months.
- Cavitating pulmonary lesion(s) or a lesion invading or encasing a major blood vessel.
- QTcF > 500 ms within 7 days of randomization.
- Unable to swallow capsules or tablets.
