Fulvestrant in Treating Patients With Advanced Prostate Cancer

This study has been completed.

Roswell Park Cancer Institute Identifier:
First received: October 25, 2005
Last updated: March 7, 2013
Last verified: March 2013

RATIONALE: Estrogen may cause the growth of prostate cancer cells. Hormone therapy using fulvestrant may fight prostate cancer by blocking the use of estrogen by the tumor cells.

PURPOSE: This phase II trial is studying how well fulvestrant works in treating patients with advanced prostate cancer.

Condition Intervention Phase
Prostate Cancer
Drug: fulvestrant
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Phase II Study of Fulvestrant (Faslodex®) in Androgen Independent Prostate Cancer

Further study details as provided by Roswell Park Cancer Institute:

Primary Outcome Measures:
  • Prostate-specific antigen (PSA) objective response rate (complete response [CR] or partial response [PR]) [ Time Frame: Monthly ]

Secondary Outcome Measures:
  • Toxicity [ Time Frame: Every Month ]

Enrollment: 20
Study Start Date: September 2005
Study Completion Date: June 2012
Primary Completion Date: October 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: fulvestrant
Detailed Description:



  • Determine if the prostate-specific antigen objective response (complete and partial response) rate is > 0.2 in patients with androgen-independent advanced prostate cancer treated with fulvestrant.


  • Determine the toxicity of this drug in these patients.

OUTLINE: This is an open-label study.

Patients receive fulvestrant intramuscularly on days 0, 14, and 28. Courses repeat once a month in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically for survival.

PROJECTED ACCRUAL: A total of 33 patients will be accrued for this study.


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


  • Histologically or cytologically confirmed adenocarcinoma of the prostate

    • Advanced disease
  • Must have androgen-independent prostate cancer meeting the following criteria:

    • Evidence of rising prostate-specific antigen (PSA) level and absolute value ≥ 5 ng/mL based on 2 measurements taken ≥ 2 weeks apart (measurements must be done after androgen deprivation [orchiectomy or luteinizing hormone-release hormone (LHRH) analogue] and antiandrogen withdrawal)
  • Rising PSA required for ≥ 28 days after antiandrogen or progestational therapy for prostate cancer (≥ 42 days after bicalutamide or nilutamide)
  • Testosterone < 50 ng/mL (unless surgically castrated)
  • Measurable or evaluable disease

    • PSA elevation constitutes evaluable disease


Performance status

  • ECOG 0-2

Life expectancy

  • Not specified


  • WBC > 3,000/mm^3
  • Neutrophil count ≥ 1,500/mm^3
  • Platelet count ≥ 100,000/mm^3
  • Hemoglobin ≥ 8 g/dL (transfusion or epoetin alfa allowed)
  • No bleeding diathesis (e.g., disseminated intravascular coagulation or clotting factor deficiency)


  • Bilirubin normal

    • Gilbert's disease with bilirubin ≤ 3 times upper limit of normal (ULN) allowed in the absence of other etiology (e.g., hemolysis-reticulocyte count < 5%) and liver function tests normal
  • SGOT and/or SGPT ≤ 2 times ULN
  • INR < 1.6


  • Creatinine < 2.5 mg/dL


  • No unstable cardiac disease requiring medication
  • No new onset crescendo or rest angina

    • Stable exertional angina allowed


  • Fertile patients must use effective barrier contraception during and for 3 months after completion of study treatment
  • No other active malignancy within the past 2 years except nonmelanoma skin cancer or superficial bladder cancer
  • No history of significant neurologic or psychiatric disorders, including psychotic disorders, dementia, or seizures
  • No other serious illness or medical condition
  • No active infection
  • No known hypersensitivity to active or inactive excipients of fulvestrant (e.g., castor oil or mannitol)


Biologic therapy

  • Prior retinoids, vaccines, and cytokines are not considered cytotoxic and are allowed


  • No more than 1 prior cytotoxic chemotherapy regimen
  • More than 3 weeks since prior chemotherapy (6 weeks for mitomycin or nitrosoureas)
  • No concurrent chemotherapy

Endocrine therapy

  • See Disease Characteristics
  • Prior glucocorticoids, antiandrogens, progestational agents, estrogens, and LHRH analogues are not considered cytotoxic and are allowed
  • At least 4 weeks since prior flutamide (6 weeks for bicalutamide or nilutamide)
  • Concurrent megestrol acetate allowed at a stable dose of ≤ 40 mg/day
  • Concurrent androgen deprivation using LHRH analogues allowed but must continue during study treatment or orchiectomy is required to maintain castrate levels of testosterone


  • More than 3 weeks since prior radiotherapy
  • No concurrent radiotherapy


  • See Disease Characteristics
  • See Endocrine therapy


  • Recovered from all prior therapy
  • Prior cholecalciferol analogues, ketoconazole, aminoglutethimide, peroxisome-proliferation-activated receptor-gamma agonists or antagonists, or PC-SPES are not considered cytotoxic and are allowed
  • No prior long-term anticoagulation therapy (antiplatelet therapy allowed)
  • More than 4 weeks since prior investigational drugs
  • No other concurrent anticancer therapy (e.g., PC-SPES)
  • No concurrent bisphosphonates unless receiving a stable dose at study entry
  • No concurrent therapy that may alter androgen metabolism or androgen levels
  • No concurrent full anticoagulation
