This study has been completed.

First received: May 6, 2003
Last updated: June 18, 2013
Last verified: April 2004

RATIONALE: Drugs used in chemotherapy such as perifosine use different ways to stop tumor cells from dividing so they stop growing or die.

PURPOSE: Phase II trial to study the effectiveness of perifosine in treating patients who have prostate cancer that no longer responds to androgen ablation therapy.

Condition Intervention Phase
Prostate Cancer
Drug: perifosine
Phase 2

Study Type: Interventional
Study Design: Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase II Trial Of Oral Perifosine In Patients With Metastatic Androgen Independent Prostate Cancer

Study Start Date: October 2003
Study Completion Date: April 2004
Detailed Description:


  • Determine the 4-month progression-free survival rate, as measured by prostate-specific antigen and clinical criteria, in patients with metastatic androgen-independent prostate cancer treated with perifosine.
  • Determine the side-effect profile of this drug in these patients.
  • Determine the pharmacokinetics and pharmacodynamics of this drug in these patients.


  • Course 1: Patients receive oral perifosine twice on day 1 and once daily on days 2-21.
  • All subsequent courses: Patients receive oral perifosine once daily on days 1-21.

In all courses, treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 22-46 patients will be accrued for this study within approximately 1.5 years.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No


  • Histologically confirmed adenocarcinoma of the prostate, meeting all of the following criteria:

    • Metastatic

  • Progression documented by at least 1 of the following parameters:

    • Two consecutively rising prostate-specific antigen levels, at least 1 week apart, with at least 1 measurement that is 50% above the nadir reached after the last treatment regimen (as long as the last measurement is at least 5 ng/mL)
    • At least 1 new metastatic lesion on technetium Tc 99m bone scintigraphy
    • Progression of soft-tissue metastases as measured by appropriate modalities (i.e., imaging or palpation) and demonstrated by at least 1 of the following:

      • Development of new area of malignant disease (measurable or nonmeasurable)
      • At least a 20% increase in the sum of the longest diameters (LD) of target lesions from the smallest sum of LD recorded since the treatment started or the appearance of 1 or more new lesions
  • Patients who have not undergone surgical castration must have a testosterone level less than 50 ng/mL and continue on their LHRH agonist during study treatment
