Apalutamide in Treating Patients With Prostate Cancer Before Radical Prostatectomy

Korábbi kezelés

• Prior hormone therapy for prostate cancer including orchiectomy, antiandrogens, ketoconazole, or estrogens (5-alpha reductase inhibitors allowed), or luteinizing hormone-releasing hormone (LHRH) agonists/antagonists
• Patients who are not appropriate surgical candidates for radical prostatectomy based on the evaluation of co-existent medical diseases and competing potential causes of death (such as but not limited to, unstable angina, myocardial infarction within the previous 6 months, or use of ongoing maintenance therapy for life-threatening ventricular arrhythmia, uncontrolled hypertension)

Más betegség

• Serious or uncontrolled co-existent non-malignant disease, including active and uncontrolled infection
• PSA is \> than 20 ng/mL (NOTE: unless other valid PSAs were =\< 20 and the treating physician considers a value \> 20 related to the biopsy or other non-malignant cause. The treating physician must consider the patient intermediate risk in aggregate)
• Uncontrolled hypertension. Patients with a history of hypertension are allowed provided blood pressure is controlled by anti-hypertensive therapy. Note that this is NOT a criterion related to particular blood pressure (BP) results at the time of assessment for eligibility, nor does it apply to acute BP excursions that are related to iatrogenic causes, acute pain or other transient, reversible causes
• Active or symptomatic viral hepatitis or chronic liver disease
• Clinically significant heart disease as evidenced by myocardial infarction, arterial thrombotic events in the past 6 months, severe or unstable angina, class III-IV New York Heart Association heart failure
• Other malignancy, except non-melanoma skin cancer, that is active or has a \>= 30% probability of recurrence within 12 months
• History of gastrointestinal disorders (medical disorders or extensive surgery) which may interfere with the absorption of the study drug
• Known history of pituitary and/or adrenal disease (or dysfunction)
• Severely compromised immunological state, including being positive for the human immunodeficiency virus (HIV)
• History of seizure, seizure disorder, or any condition that may predispose to seizure including, but not limited to underlying brain injury, stroke, primary brain tumors, brain metastases, or alcoholism. Also, history of loss of consciousness or transient ischemic attack within 12 months of enrollment (day 1 visit). Drugs may not be used which are known to decrease the seizure threshold

Egyéb

• Histological variants in the primary tumor, other than adenocarcinoma; for example: neuroendocrine tumor, small cell or sarcomatoid

• Willing and able to provide written informed consent
• Histologically confirmed adenocarcinoma of the prostate
• A minimum of 10 core biopsies have been performed at baseline and available. A prostate biopsy within 6 months from screening is allowed for entry requirements. Biopsies performed within 6-12 months from screening are acceptable if the treating physician would allow treatment without further biopsy. Patients must meet intermediate risk criteria from Gleason score, T stage, and prostate-specific antigen (PSA) value by National Comprehensive Cancer Network (NCCN) criteria: cT2b-T2c or Gleason 7 (3+4 or 4+3) or PSA 10-20 ng/mL. In addition, the Gleason 3+4 or 4+3 must be present
• Pathology review at MD Anderson Cancer Center. The volume of disease must be high enough for the surgeon to agree to include an extended template pelvic lymph node dissection
• Serum testosterone \> 200 ng/mL
• Patient and urologist must agree that patient is suitable for prostatectomy
• No evidence of metastases on imaging. This risk group does not require metastatic studies, but if performed they must be negative (as determined by urologist or radiologist). Suspicious lymph nodes permissible if \< 10 mm
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
• Hemoglobin \>= 10.0 g/dL
• Platelet count \>= 100,000 x 10\^9/microliter
• Glomerular filtration rate (GFR) \>= 45 mL/min
• Serum potassium \>= 3.5 mmol/L
• Serum albumin \>= 3.0 g/dL
• Able to swallow the study drug whole as a tablet
• Serum bilirubin \< 1.5 x upper limit of normal (ULN); Note: In subjects with Gilbert's syndrome, if total bilirubin is \> 1.5 x ULN, measure direct and indirect bilirubin and if direct bilirubin is =\< 1.5 x ULN, subject may be eligible
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< 2.5 x ULN
• Normal coagulation profile and no history of substantial non-iatrogenic bleeding diathesis
• Agrees to use a condom (even men with vasectomies) and another effective method of birth control if he is having sex with a woman of childbearing potential or agrees to use a condom if he is having sex with a woman who is pregnant while on study drug and for 3 months following the last dose of study drug. Must also agree not to donate sperm during the study and for 3 months after receiving the last dose of study drug
