  Purpose

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor.

PURPOSE: This phase II trial is studying the side effects of everolimus and to see how well it works as first-line therapy in treating patients with prostate cancer.

Primary Outcome Measures:
  • Progression-free survival [ Time Frame: at 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Progression-free survival [ Time Frame: at 24 weeks ] [ Designated as safety issue: No ]
  • Progression-free survival [ Time Frame: from start of treatment until progression or death of any cause ] [ Designated as safety issue: No ]
    from start of treatment until progression or death of any cause, whereas it will be censored at the last follow-up visit or initiation of a different treatment.

  • Adverse events according to NCI CTCAE v. 3.0 [ Time Frame: from start of treatment until progression or death of any cause ] [ Designated as safety issue: Yes ]
  • PSA response [ Time Frame: 50% and 30%, best and at 12 weeks ] [ Designated as safety issue: No ]
  • Changes in PSA-doubling time [ Time Frame: Time points for later calculations include: after 12 weeks, after 24 weeks and at best PSA response ] [ Designated as safety issue: No ]
  • Tumor assessment of measurable disease according to RECIST v1.1 criteria [ Time Frame: The first assessment will be performed after 12 weeks of treatment, or earlier if clinically indicated. ] [ Designated as safety issue: No ]
  • Tumor assessment of bone lesions [ Time Frame: at 12 weeks. ] [ Designated as safety issue: No ]

Detailed Description:

OBJECTIVES:

Primary

  • Determine the progression-free survival at 12 weeks of patients with non-rapidly progressive castration-resistant prostate cancer treated with everolimus as first-line therapy.
  • Assess the activity and safety of this regimen in these patients.

Secondary

  • Determine the progression-free survival at 24 weeks of patients treated with this regimen.
  • Determine the percentage of PSA response from baseline to 12 weeks in patients treated with this regimen.
  • Determine the changes in PSA-doubling time in patients treated with this regimen.
  • Determine the overall survival of patients treated with this regimen.

OUTLINE: This is a multicenter study.

Patients receive oral everolimus once daily on days 1-28. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study therapy, patients are followed up at 28 days and then every 3 months.

  Eligibility

Ages Eligible for Study:   18 Years and older

Criteria

DISEASE CHARACTERISTICS:

  • Histologically confirmed metastatic or locally advanced adenocarcinoma of the prostate

    • No curative therapy available
    • Oligosymptomatic or asymptomatic patients
  • Tumor progression after ≥ 1 hormonal treatment (orchiectomy or luteinizing-hormone releasing-hormone [LHRH] agonist) with documented total testosterone levels ≤ 1.7 nmol/L (≤ 50 ng/dL)

    • Concurrent LHRH agonist therapy is required for patients who have not been surgically castrated
    • Must have stopped antiandrogen therapy ≥ 6 weeks before the start of trial treatment without withdrawal response
  • PSA progression defined as an increase in PSA ≥ 25% (and an absolute increase of 2 ng/mL or more) over nadir value on hormonal therapy measured on 3 successive occasions ≥ 1 week apart

    • If the third measurement is not higher than the second, a fourth measurement will be taken (patient allowed if the fourth measurement is higher than the second)
    • PSA doubling time ≥ 55 days
  • No known or suspected CNS metastases

PATIENT CHARACTERISTICS:

  • WHO performance status 0-1
  • ANC ≥ 1,500/mm^3
  • Platelet count ≥ 100,000/mm^3
  • Hemoglobin ≥ 90 g/L
  • Bilirubin ≤ 1.5 times upper limit of normal (ULN)
  • AST ≤ 2.5 times ULN
  • Creatinine clearance ≥ 40 mL/min
  • Fasting serum cholesterol ≤ 7.75 mmol/L AND fasting triglycerides ≤ 2.5 times ULN

    • Appropriate lipid-lowering medication allowed in case one or both of these thresholds are exceeded
  • Patient compliance and geographic proximity that would allow proper staging and follow-up are required
  • No malignancy within the past 5 years except curatively treated localized nonmelanoma skin cancer or Ta and Tis bladder cancer
  • No known history of HIV
  • No serologically confirmed hepatitis B or C
  • No serious underlying medical condition that, in the judgment of the investigator, could impair the ability of the patient to participate in the trial including, but not limited to, any of the following conditions:

    • Uncontrolled or acute severe infection
    • Uncontrolled diabetes
    • Advanced chronic obstructive pulmonary disease
  • No psychiatric disorder precluding understanding of information on trial-related topics, giving informed consent, or interfering with compliance for oral drug intake

  • No major surgery within the past 4 weeks
  • No concurrent radiotherapy
  • No concurrent angiotensin converting enzyme inhibitors
  • No concurrent chronic immunosuppressive therapy including high-dose corticosteroids (i.e., > 25 mg prednisone equivalent per day)
  • No products known to affect PSA levels (e.g., PC Calm, PC Plus, PC SPES, finasteride, or fluconazole) within the past 4 weeks or concurrently
  • No strong CYP3A4 inhibitors (e.g., itraconazole, erythromycin, clarithromycin, diltiazem, verapamil, or grapefruit or its juice) within the past 2 weeks or concurrently
  • No strong CYP3A4 inducers (e.g., phenytoin, rifampicin, carbamazepine, phenobarbital, or St. John wort) within the past 2 weeks or concurrently
  • No concurrent bisphosphonates

    • Patients must continue to receive bisphosphonates regularly if it was started prior to entering the trial
  • No concurrent experimental drugs or other anticancer therapy in a clinical trial within the past 30 days
  • No concomitant drugs contraindicated for use with the trial drug according to the investigator's drug brochure
