Paclitaxel and Bryostatin 1 in Treating Patients With Metastatic Prostate Cancer

This study has been completed.
National Cancer Institute (NCI)
Information provided by (Responsible Party):
University of Maryland Identifier:
First received: April 6, 2000
Last updated: March 28, 2017
Last verified: March 2017
Phase II trial to study the effectiveness of combining paclitaxel and bryostatin 1 in treating patients who have metastatic prostate cancer that has not responded to hormone therapy. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

Condition Intervention Phase
Prostate Cancer Drug: bryostatin 1 Drug: paclitaxel Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study of Weekly Paclitaxel and Bryostatin-1 in Hormone Refractory Prostate Cancer

Enrollment: 46
Actual Study Start Date: May 2000
Study Completion Date: July 2006
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 and bryostatin 1 IV over 1 hour on days 2, 9, and 16. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.
Drug: bryostatin 1 Drug: paclitaxel

Detailed Description:


I. Determine the onset, duration, and degree of response in patients with hormone-refractory, metastatic adenocarcinoma of the prostate treated with paclitaxel and bryostatin 1.

II. Determine the toxicity of this regimen in these patients. III. Determine the overall survival of patients treated with this regimen.

OUTLINE: This is an open-label, multicenter study.

Patients receive paclitaxel IV over 1 hour on days 1, 8, and 15 and bryostatin 1 IV over 1 hour on days 2, 9, and 16. Treatment repeats every 4 weeks in the absence of disease progression or unacceptable toxicity.

Patients are followed monthly for 6 months and then every 3 months thereafter.


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


  • Histologically confirmed metastatic adenocarcinoma of the prostate that failed first- or second-line hormonal therapy (e.g., gonadal androgen suppression [orchiectomy or luteinizing hormone-releasing hormone] with or without antiandrogens)

    • Failure on hormonal therapy is defined by 1 of the following criteria:

      • Biochemical progression (after withdrawal of antiandrogens), documented by 3 rising PSA values, each value measured at least 2 weeks apart, with the last measurement being at least 25% of the nadir achieved while on hormonal therapy and with an increase in the absolute value by at least 5 ng/mL
      • Measurable disease progression, defined by an increase in the sum of the products of the perpendicular diameters of any measurable lesion(s) by at least 25%
  • Bone only progression allowed only with concurrent biochemical progression
  • Castrate levels of testosterone (no greater than 50 ng/dL)
  • No clinical signs/symptoms suggesting CNS metastases
