Everolimus in Treating Patients With Newly Diagnosed Localized Prostate Cancer

2018年11月14日 更新者:Jorge A. Garcia, MD

Randomized Phase II Study of Two Different Doses of RAD-001 (Everolimus) as Neo-Adjuvant Therapy in Patients With Localized Prostate Cancer

RATIONALE: Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving everolimus before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

PURPOSE: This randomized phase II trial is studying the side effects and how well everolimus works in treating patients with newly diagnosed localized prostate cancer.

研究概览

详细说明

OBJECTIVES:

Primary

  • To determine the clinical effects of everolimus, in terms of pathologic response (i.e., histologic P0, margin status, or capsular penetration) and surgical outcome, in patients with newly diagnosed localized prostate cancer treated with two different doses of everolimus prior to radical prostatectomy.
  • To evaluate the safety and tolerability of this drug in these patients.

Secondary

  • To determine the effect of this drug on prostate-specific antigen (PSA) levels in these patients.
  • To determine the effect of this drug on levels of expression of PTEN, Akt, phospho-mTOR (i.e., Se2448), phospho-p70 S6 kinase (i.e., Thre389), phospho-Smad3 (i.e., Ser433/435), phospho-Smads 1/5 (i.e., Ser463/465), AR, and TUNEL in these patients.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients receive low-dose oral everolimus once daily for up to 8 weeks in the absence of unacceptable toxicity.
  • Arm II: Patients receive high-dose oral everolimus once daily for up to 8 weeks in the absence of unacceptable toxicity.

Within 7 days after the last dose of everolimus, all patients undergo radical prostatectomy with bilateral pelvic lymphadenectomy.

Tumor biopsy specimens acquired prior to treatment and prostate tumor tissue acquired at the time of radical prostatectomy are evaluated for biomarker correlative studies. Tissue samples are assessed by immunohistochemistry (IHC) and tissue microarray analysis for expression of cellular and molecular biomarkers (i.e., p-S6, p-4E-BP1, and p-Akt) that correlate with response. Prostatectomy specimens are also assessed by pathologic analysis for histopathologic response (i.e., pathologic stage, Gleason score, margin status, and tumor size).

After completion of study therapy, patients are followed at 6 weeks.

  • No metastatic disease by CT scan, MRI, bone scan, or X-ray
  • No clinical evidence of CNS metastases

PATIENT CHARACTERISTICS:

Inclusion criteria:

Exclusion criteria:

  • Known hypersensitivity to everolimus or other rapamycins (e.g., sirolimus or temsirolimus) or to its excipients
  • Gastrointestinal (GI) disease, condition, or symptoms that may significantly impair GI function and alter the absorption of everolimus, including any of the following:

    • Ulcerative disease
    • Uncontrolled nausea
    • Vomiting
    • Diarrhea
    • Malabsorption syndrome
  • Other active malignancy or malignancy at ≥ 30% risk for relapse after completion of therapy, except nonmelanoma skin cancer
  • Uncontrolled concurrent illness including, but not limited to, any of the following:

    • Ongoing or active infection (e.g., bacterial, viral or fungal)

    • Symptomatic congestive heart failure
    • Unstable angina pectoris
    • Cardiac arrhythmia
  • Psychiatric illness or social situation that would limit study compliance
  • Any underlying medical condition which, in the principal investigator's opinion, will make the administration of everolimus hazardous OR obscure the interpretation of adverse events
