Further study details as provided by Massachusetts General Hospital:

Primary Outcome Measures:
  • To compare the effects of Atrasentan monotherapy with combination therapy using Atrasentan and Zometa on bone specific alkaline phosphatase.

Secondary Outcome Measures:
  • To evaluate the effects of Atrasentan monotherapy and combination therapy with Atrasentan and Zometa on PSA doubling time.

Estimated Enrollment: 44
Study Start Date: December 2001
Study Completion Date: December 2006
Primary Completion Date: December 2006 (Final data collection date for primary outcome measure)
Detailed Description:
  • Patients will be randomized to either receive Atrasentan alone or Atrasentan plus Zometa.
  • Patients receiving Atrasentan alone will receive this drug in pill form once daily for 12 weeks. Patients will have a physical exam, blood work, and a urine sample performed once every other week during the first four weeks of medication administration. After those two initial visits, they will return to the clinic once every 4 weeks to have the same tests repeated. A bone scan and abdominal-pelvic CT Scan will be done every 12 weeks.
  • After the patient has been taking Atrasentan for 12 weeks, if the disease has not progressed, they will begin combination treatment of Atrasentan and Zometa.
  • Patients receiving Atrasentan plus Zometa, receive Zometa intravenously and then immediately start Atrasentan orally once daily as long as they remain on the study. Patients will return to the clinic twice over the first 4 weeks (once every other week) to have a physical exam, blood work and urine test performed. After these two initial visits, they will return to the clinic once every 4 weeks to have the tests repeated and to receive another treatment of zometa. A bone scan and an abdominal-pelvic CT Scan will be done once every 12 weeks.
  • Patients participation in this study will last as long as the disease does not progress and they are not experiencing any serious side effects.
