SU5416 Compared to Dexamethasone in Treating Patients With Progressive Prostate Cancer That Has Not Responded to Hormone Therapy

September 4, 2013 updated by: University of Chicago

A Phase II Trial of SU5416 (NSC# 686819) in Patients With Hormone Refractory Prostate Cancer

RATIONALE: SU5416 may stop the growth of prostate cancer by stopping blood flow to the tumor. Dexamethasone may be effective in slowing the growth of prostate cancer cells. It is not yet known whether SU5416 or dexamethasone is more effective in treating progressive prostate cancer.

PURPOSE: Randomized phase II trial to compare the effectiveness of SU5416 with that of dexamethasone in treating patients who have progressive prostate cancer that has not responded to hormone therapy.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

OBJECTIVES:

  • Compare the time to progression in patients with hormone refractory prostate cancer treated with dexamethasone with or without SU5416.
  • Determine the differences in PSA kinetics and PSA hazard score between these two regimens in this patient population.
  • Determine the objective response rate and time to development of new lesions in these patients treated with SU5416.
  • Determine the toxicity of SU5416 in these patients.

OUTLINE: This is a randomized study. Patients are randomized to one of two treatment arms.

  • Arm I: Patients receive oral dexamethasone once a day 6 days a week. Treatment continues until disease progression, at which time patients cross over to arm II.
  • Arm II: Patients receive oral dexamethasone as in arm I followed by SU5416 IV over 60 minutes twice weekly for 4 weeks. A smaller dose of dexamethasone is administered the day after SU5416. Treatment continues for a minimum of 2 courses in the absence of unacceptable toxicity or disease progression.

PROJECTED ACCRUAL: A total of 60 patients (30 per arm) will be accrued for this study within 16 months.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
