A Phase II Trial of TPI 287 in Patients With Metastatic Prostate Cancer
A Phase II Trial of TPI 287 in Patients With Metastatic Prostate Cancer Who Have Progressive Neoplastic Disease Following Treatment With One Prior Taxane Regimen
The primary objective of the study is to determine the response rate to TPI 287 in patients with metastatic, hormone-refractory prostate cancer who have had one prior taxane regimen.

This is an open-label, multi-center, 2-stage Simon design, Phase 2 study of TPI 287 in patients with metastatic, hormone-refractory prostate cancer. All patients must have received prior taxane therapy. Up to 80 patients will be enrolled and stratified based on duration of cumulative exposure to a single prior taxane regimen. A single taxane regimen is considered to he a taxane or taxane containing therapy administered on a defined schedule with no more than 2 months' interruption between treatments, and total exposure will be assessed by the number of months on that schedule.

One stratum (up to 40 patients) will consist of patients who have had over 3 months (up to a maximum of 10 months) exposure to a taxane regimen, who then have documented progression of disease (initially taxane sensitive). The second stratum (up to 40 patients) will consist of patients considered primarily resistant to taxanes who have had documented progressive disease as best response after exposure to a single taxane regimen for less than or equal to 3 months. Patients may have received prior hormonal therapy and/or bisphosphonates and may continue on these therapies.

In the first stage of the trial, 22 patients in each stratum will be treated with TPI 287 intravenously every 21 days. If 1 or fewer patients in either stratum demonstrate a response in this first stage, the trial will be discontinued for that stratum. Otherwise, an additional 18 patients in the stratum showing 2 or more responses will be enrolled in the second stage of the study. If 4 or fewer patients demonstrate a response in the total study population in either stratum from stages 1 and 2, then the drug will not be considered of interest in prostate cancer for patients as defined in that stratum.

  • Platelet count greater than or equal to 100,000/UL Recovered from the effects of prior surgery, radiotherapy or other antineoplastic therapy.

Exclusion Criteria:

  • Active infection or with a fever greater than or equal to 38.5 degrees centigrade within 3 days of first scheduled day of dosing
  • More than one prior systemic therapy for HRPC beyond androgen-ablative therapy. Prior systemic therapy may have been administered for metastatic disease or as adjuvant therapy
  • Has received radiotherapy to greater than 30% of their active bone marrow
  • History of prior malignancy within the past 5 years except for curatively treated non-melanoma skin cancer
  • Impending fracture of a weight bearing bone
  • Known hypersensitivity to any of the components of TPI 287
  • Receiving concurrent investigational therapy or who have received investigational therapy within 30 days of study start
  • Grade 2 peripheral neuropathy
  • NYHA Class 3 or 4 congestive heart failure
  • Any medial condition that would interfere with ability to sign ICF, cooperate and participate in the study or interfere with interpretation of results
