Synopsis

Treatment Agent: Radiation therapy, Apalutamide

Synopsis: The purpose of this study is to compare any good and bad effects of using the drug apalutamide (study drug) along with usual radiation therapy to using usual radiation therapy alone. The study drug is a hormone suppression drug. The study drug is FDA approved for the treatment of non-metastatic castration resistant prostate cancer; however, the study drug is still considered investigational in this trial setting. The addition of the study drug to usual radiation could shrink your cancer/prevent it from returning, but it could also cause side effects. This study will allow the researchers to know whether this different approach is better, the same, or worse than the usual approach. To be better, the study drug should reduce the chance of your cancer growing back  compared to the usual approach.

Exclusion Criteria

Exclusion Criteria:

  • Definitive clinical, radiologic, or pathologic evidence of metastatic disease (M1) or lymph node involvement (N1)
  • Prior invasive malignancy (except non-melanomatous skin cancer, carcinoma in situ of the male breast, penis, oral cavity, or stage Ta of the bladder, or stage I completely resected melanoma) unless disease free for a minimum of 2 years
  • Prior systemic chemotherapy for the study cancer; note that prior chemotherapy for a different cancer is allowable
  • Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields
  • History of any of the following:
    • Seizure or known condition that may pre-dispose to seizure (e.g. prior stroke within 1 year prior to Step 1 registration)
    • History of documented inflammatory bowel disease
    • Transmural myocardial infarction within the last 4 months prior to Step 1 registration.
    • Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months prior to Step 1 registration
    • History of any condition that in the opinion of the investigator, would preclude participation in this study
  • Current evidence of any of the following:
    • Known gastrointestinal disorder affecting absorption of oral medications
    • Active uncontrolled infection (eg, human immunodeficiency virus [HIV] or viral hepatitis)
    • Uncontrolled hypertension
    • Any current condition that in the opinion of the investigator, would preclude participation in this study
  • Prior whole gland ablative therapy (i.e. cryoablation or high intensity focused ultrasound [HIFU]) for prostate cancer is not allowed
  • HIV positive with CD4 count < 200 cells/microliter within 30 days prior to registration
  • HIV patients under treatment with highly active antiretroviral therapy (HAART) within 30 days prior to registration regardless of CD4 count. (Note: HIV testing is not required for eligibility for this protocol as it is self-reported.)
  • For patients who have not undergone prior Decipher analysis, submission of the specimen to GenomeDx should be as soon as possible after study registration (Step 1) as these results can take up 21 days after the specimen is received at GenomeDx; Step 2 registration must occur within 6 weeks (42 days) of Step 1 registration; if Decipher results have already been obtained, in lieu of tissue, results must be submitted to GenomeDx for validation

Inclusion Criteria

Inclusion Criteria:

  • Pathologically (histologically) proven diagnosis of prostate adenocarcinoma; prostatectomy must have been performed within 10 years prior to Step 1 registration and any type of radical prostatectomy is permitted, including retropubic, perineal, laparoscopic or robotically assisted
  • Post-prostatectomy patients with a detectable serum PSA (≥ 0.1, but ≤ 1.0 ng/mL) at study entry (within 90 days of Step 1 registration) and at least one of the following:
  • pN0 or pNx
  • History/physical examination within 90 days prior to Step 1 registration
  • Karnofsky performance status of 70-100 within 90 days prior to Step 1 registration
  • Surgical formalin-fixed paraffin-embedded (FFPE) specimen must be available for submission to GenomeDx for genomic analysis on Decipher GRID platform; Note: if Decipher results have already been obtained, in lieu of tissue, results must be submitted to GenomeDx for validation
  • Prior androgen deprivation therapy (luteinizing hormone-releasing hormone [LHRH] agonist and/or non-steroidal anti-androgen) is allowed if discontinued at least 90 days prior to Step 1 registration and given for ≤ 90 days duration
  • Hemoglobin ≥ 9.0 g/dL, independent of transfusion and/or growth factors within 90 days prior to Step 1 registration
  • Platelet count ≥ 100,000 x 10^9/uL independent of transfusion and/or growth factors within 90 days prior to step 1 registration
  • Serum albumin ≥ 3.0 g/dL within 90 days prior to Step 1 registration
  • Glomerular filtration rate (GFR) ≥ 35 mL/min estimated by Cockcroft-Gault or measured directly by 24 hour urine creatinine within 90 days prior to Step 1 registration
  • Serum total 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 is eligible) within 90 days prior to Step 1 registration
  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) < 2.5 x ULN within 90 days prior to Step 1 registration
  • Testosterone > 50 ng/dL within 90 days prior to Step 1 registration
  • Concomitant medications known to lower the seizure threshold discontinued or substituted at least 4 weeks (30 days) prior to Step 1 registration.
  • The patient must agree 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 agree 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
  • The patient must agree not to donate sperm during the study treatment and for 3 months after receiving the last dose of study drug
  • The patient or a legally authorized representative must provide study-specific informed consent prior to study entry
