New trial combines drugs with surgery or radiation to fight advanced prostate cancer

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age \> 18 * Histologically confirmed diagnosis of prostate adenocarcinoma * Metastatic disease documented by ≥1 bone lesion with Technetium 99m (99mTc) bone scan. Individuals with only one bone lesion should have confirmation of that lesion on CT or MRI. * Eastern Cooperative Oncology Group Performance Status (ECOG PS) Grade ≤ 2 * No previous treatment with antiandrogens or GnRH analogues, or a treatment ≤ 3 months. * No previous systemic or local treatment for prostate adenocarcinoma, including pelvic radiotherapy. * Laboratory values at the time of screening: a. Neutrophils ≥ 1500/μL b. Hemoglobin ≥ 9.0 mg/μL (no transfusions in the past 28 days) c. Platelets ≥ 100,000/μL d. Creatinine ≤ 2 x upper limit of normal and serum albumin ≥ 3.0 g/dL f. Total bilirubin ≤ 1.5 x upper limit of normal \[NOTE: In subjects with Gilbert syndrome, if total bilirubin is \>1.5 x ULN, measure direct and indirect bilirubin, and if direct bilirubin is ≤ 1.5 x ULN subjects may be eligible\]; g. AST and ALT ≤ 2.5 x upper limit of normal * Able to swallow Apalutamide tablets whole. * All subjects must sign an Informed Consent Form indicating that they understand the purpose of the study and its procedures and intend to participate. The subject must be willing and must be able to comply with the restrictions specified in this protocol. Inclusion criteria for cytoreductive surgery: * Age \>18 years * Clinical stage cT3 * Robot-assisted radical prostatectomy with iliac obturator lymphadenectomy * Surgical piece management criteria similar to Proteus criteria. Exclusion Criteria: * Pathologic findings consistent with small cell, ductal, or neuroendocrine prostate cancer. * Known brain metastases. * Lymph node metastases only. * Visceral metastases. * Patients not eligible for surgery or radiotherapy. * Unacceptable increase in cardiovascular risk, defined as the occurrence of at least one of the following episodes in the 6 months prior to randomization: unstable angina, myocardial infarction, symptomatic congestive heart failure, clinically significant thromboembolic events (e.g., pulmonary embolism), or clinically significant ventricular arrhythmias . * Uncontrolled high blood pressure (systolic blood pressure \> 160 mmHg or diastolic blood pressure \> 100 mmHg). * Previous treatment with antiandrogens, GnRH analogues, or other systemic treatments for adenocarcinoma of the prostate. * Previous local treatment with surgery and/or radiotherapy. * Any prior malignancy (except adequately treated basal cell carcinoma or a squamous cell skin carcinoma, superficial bladder carcinoma, or any other in situ carcinoma currently in complete remission) within 5 years of randomization. * Known allergies, hypersensitivity or intolerance to the excipients of Apalutamide. * Patients who, within 28 days prior to randomisation, have received: 1. transfusions (red blood cells and/or platelets); 2. hematopoietic growth factors; 3. major surgery. * Symptomatic and/or chronic viral hepatitis; chronic liver disease; moderate or severe liver failure (class B and C according to the Child-Pugh scale); encephalopathy, ascites or thrombo-haemorrhagic disorders secondary to liver failure. * Gastrointestinal disorders affecting drug absorption * Active infections requiring systemic therapy such as human immunodeficiency virus (HIV); * Any condition or situation which, in the judgment of the investigator, precludes participation in this trial. Exclusion criteria for cytoreductive surgery: * Contraindication for surgery
