This is a phase I/II, open-label, dose escalation study of HE3235 administered orally to patients with advanced prostate cancer who have failed hormone therapy and at least one taxane based chemotherapy regimen.

Condition Intervention Phase
Prostate Cancer
Drug: HE3235
Phase 1
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase I/II, Open-Label, Dose Ranging Study of the Safety, Tolerance, Pharmacokinetics and Potential Activity of HE3235 When Administered Orally to Patients With Prostate Cancer

Further study details as provided by Harbor Therapeutics:

Primary Outcome Measures:
  • To evaluate the safety and tolerance of HE3235 when administered orally to prostate cancer patients in 28 day cycles. [ Time Frame: Treatment period ]
  • To evaluate the pharmacokinetic profiles of HE3235 and major metabolites at different dose levels after 28 days of dosing. [ Time Frame: Treatment period ]
  • To assess potential activity of HE3235 in prostate cancer patients. [ Time Frame: Treatment period and post-study follow-up period ]

Secondary Outcome Measures:
  • Explore circulating tumor cell (CTC) enumeration in response to treatment as a marker evaluating whether an investigational therapy is effective for tumor treatment [ Time Frame: Treatment period ]
  • Evaluate the role of molecular profiling of CTC in predicting sensitivity to treatment and treatment response. [ Time Frame: Treament period and post-study follow-up ]

Enrollment: 64
Study Start Date: July 2008
Study Completion Date: March 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: HE3235
    HE3235 will be administered orally in 28 day cycles.
