The purpose of this study is to evaluate PTK787/ZK 222584, a drug that blocks new blood vessel growth, in the treatment of patients with non-metastatic androgen independent prostate cancer. This study will assess the safety and tolerability of PTK787/ZK 222584, and evaluate serum vascular endothelial growth factor (VEGF) levels.

Further study details as provided by University of Michigan:

Primary Outcome Measures:
  • Assess the efficacy of PTK787/ZK 222584 in terms of prostate-specific antigen (PSA) response, in patients with hormone-refractory prostate cancer

Secondary Outcome Measures:
  • Evaluate the toxicity in patients treated with PTK787/ZK 222584
  • Assess overall survival in patients treated with PTK787/ZK 222584
  • Assess effect of PTK787/ZK 222584 on circulating VEGF levels in patients treated with PTK787/ZK 222584

Estimated Enrollment: 40
Study Start Date: July 2005
Study Completion Date: April 2008
Detailed Description:

This is an open-label, phase II trial of PTK787/ZK 222584. Patients will receive 750 mg daily for one week, 1000 mg daily for the second week, and then 1250 mg per day thereafter.

Response Assessment: In the absence of toxicity or clinical progression, patients will remain in the study until their PSA has doubled from pretreatment baseline.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients must have rising PSA as demonstrated by two rising values at least one month apart while receiving hormonal therapy.

Exclusion Criteria:

  • Patients must not be on nonsteroidal antiandrogen blockade.
