Docetaxel and Prednisone With or Without Bevacizumab in Treating Patients With Prostate Cancer That Did Not Respond to Hormone Therapy

A Randomized Double-Blinded Placebo Controlled Phase III Trial Comparing Doctaxel and Prednisone With and Without Bevacizumab (IND #7921, NSC #704865) in Men With Hormone Refractory Prostate Cancer

This randomized phase III trial is studying docetaxel, prednisone, and bevacizumab to see how well they work compared to docetaxel and prednisone in treating patients with prostate cancer that did not respond to hormone therapy. Drugs used in chemotherapy, such as docetaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Bevacizumab may also stop the growth of tumor cells by blocking blood flow to the tumor. It is not yet known whether docetaxel, prednisone, and bevacizumab are more effective than docetaxel and prednisone in treating prostate cancer.

Study Overview

• Status: Completed
• Conditions: Recurrent Prostate Cancer; Hormone-resistant Prostate Cancer; Adenocarcinoma of the Prostate; Stage IV Prostate Cancer
• Intervention / Treatment: Other: laboratory biomarker analysis; Biological: bevacizumab; Drug: prednisone; Drug: docetaxel; Other: placebo

Detailed Description

PRIMARY OBJECTIVES:

I. To determine if the addition of bevacizumab to docetaxel and prednisone increases overall survival compared to docetaxel and prednisone alone in patients with HRPC.

SECONDARY OBJECTIVES:

I. To compare the progression-free survival of these two regimens in patients with HRPC.

II. To compare the two regimens on the proportion of patients who experience a 50% post-therapy PSA decline from baseline.

III. To compare the two regimens with respect to the proportion of patients who experience grade 3 or higher toxicities.

OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to predicted 24-month survival probability (< 10% vs 10-29.9% vs ≥ 30%), age (< 65 years vs ≥ 65 years), and prior history of arterial events (i.e., cardiac ischemia/infarction, CNS cerebrovascular ischemia, peripheral arterial ischemia, or CNS hemorrhage) (yes vs no). Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive docetaxel IV over 1 hour and placebo IV over 30-90 minutes on day 1. Patients also receive oral prednisone once daily on days 1-21.

ARM II: Patients receive docetaxel and prednisone as in arm I. Patients also receive bevacizumab IV over 30-90 minutes on day 1.

In both arms, courses repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically for up to 5 years.

Description

Inclusion Criteria:

• Patients must have histologically documented adenocarcinoma of the prostate with progressive systemic (clinically metastatic disease documented on bone, CT or MRI scan) disease despite castrate levels of testosterone due to orchiectomy or LHRH agonist; castrate levels of testosterone must be maintained
• All eligible patients must have a Gleason sum based on biopsy or TURP at the time of registration

• At the time of enrollment, patients must have evidence of progressive metastatic disease, either:

  • Measurable disease with any level of serum PSA OR
  • Non-measurable disease with PSA ≥ 5 ng/ml; patients with PSA ≥ 5 ng/ml only and no other radiographic evidence of metastatic prostate cancer are not eligible

• Definition of Measurable Disease/Target Lesions:

  • Any lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 20 mm with conventional techniques: 1) physical exam for clinically palpable lymph nodes and superficial skin lesions, 2) chest X-ray for clearly defined lung lesions surrounded by aerated lung OR those lesions measured as ≥ 10 mm with a spiral CT or MRI scan

  • Measurable lesions (up to a maximum of 10 in number) representative of all organs involved to be identified as target lesions; the sum of the longest diameters (LD) for all target lesions will be calculated and reported as baseline sum LD

    • If measurable disease is confined to a solitary lesion and is not consistent with prostate cancer, then its neoplastic nature must be confirmed by histology
    • Ultrasound may not be used to measure tumor lesions that are not easily accessible clinically

• Definition of Non-measurable Disease/Non-target Lesions:

  • Non-target lesions include all other lesions not included in above, including small lesions with longest diameter < 20 mm with conventional techniques or < 10 mm with spiral CT scan and truly non-measurable lesions, which include:

    • Bone lesions
    • Pleural or pericardial effusions, ascites
    • CNS lesions, leptomeningeal disease
    • Irradiated lesions, unless progression documented after RT

• Patients must have demonstrated evidence of progressive disease since the most recent change in therapy; progressive disease is defined as any one of the following (measurable disease, bone scan, or PSA progression):

  • Measurable Disease Progression: Objective evidence of increase > 20% in the sum of the longest diameters (LD) of target lesions from the time of maximal regression or the appearance of one or more new lesions
  • Bone Scan Progression: Appearance of one or more new lesions on bone scan attributable to prostate cancer along with a PSA ≥ 5 ng/ml will constitute progression

  • PSA Progression: An elevated PSA (≥ 5 ng/mL) which has risen serially on at least two occasions after the discontinuation of antiandrogen therapy, each at least one week apart; if the confirmatory PSA (#3) value is less than screening PSA (#2) value, then an additional test for rising PSA (#4) will be required to document progression

    • The reference PSA value (#1) must be measured at the time of the discontinuation of antiandrogen therapy; and at least 2 PSA measurements must be made following the end of antiandrogen therapy and prior to registration
    • (For the purposes of the nomogram calculator, the last PSA value recorded prior to the initiation of treatment will be considered the baseline PSA)
• Progression despite standard androgen deprivation therapy (i.e., LHRH agonist and/or orchiectomy)

• All antiandrogens (e.g., flutamide, megestrol acetate [even if taken for hot flashes], bicalutamide and nilutamide) of any dose must be discontinued at least 4 weeks prior to registration; if improvement following antiandrogen withdrawal is noted, progression must be established using the criteria above

  • Primary testicular androgen suppression (e.g., with an LHRH agonist) should not be discontinued
• At least 4 weeks since any other hormonal therapy, including ketoconazole and aminoglutethimide; the only exception to this time frame is that 5α-reductase inhibitors (e.g., finasteride, dutasteride) may be discontinued any time prior to registration
• No prior cytotoxic chemotherapy, including estramustine or suramin
• No prior anti-angiogenesis agents, including thalidomide and bevacizumab

• ≥ 4 weeks since any prior radiation (including palliative) and fully recovered
• ≥ 8 weeks since the last dose of Strontium-89 or Samarium

• Patients receiving a bisphosphonate must be on a stable dose and must have started the bisphosphonate ≥ 4 weeks prior to initiating protocol treatment. Patients do not have to be on a bisphosphonate to qualify for the study; patients may initiate bisphosphonate therapy after completion of Cycle 1, if clinically indicated

  • Patients enrolled on CALGB 90202 who have documented disease progression and have received at least 4 weeks of open label zoledronic acid treatment, are eligible for this study.
• No known brain metastases (brain imaging (MRI/CT) is not required)
• No current congestive heart failure (New York Heart Association Class II, III or IV)
• Patients with history of hypertension must be well controlled (< 160/90) on a regimen of anti-hypertensive therapy
• Patients on full-dose anticoagulants must be on a stable dose of warfarin and have an in-range INR (usually between 2 and 3) or be on a stable dose of LMW heparin; patients receiving anti-platelet agents are also eligible; in addition, patients who are on daily prophylactic aspirin or anticoagulation for atrial fibrillation are eligible
