This is an interventional treatment trial for Prostate Cancer Read More

Inclusion criteria:

• Patients with metastatic castration-resistant prostate cancer (mCRPC) previously treated with chemotherapy including docetaxel.
• Male patients.
• Patients must have either measurable or nonmeasurable disease, or documented rising PSA levels.
• Patients signed informed consent.

Exclusion criteria:

• Age <20 at registration.
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) ≥2.

• Inadequate organ and bone marrow function at registration as evidenced by:

  • Hemoglobin <10.0 g/dL.
  • ANC <5 x 10^9/L.
  • Platelet count <100 x 10^9/L.
  • Aspartate transaminase (AST) and/or alanine aminotransferase (ALT) >1.5 x upper limit of normal (ULN).
  • Total bilirubin >1.0 x ULN.
  • Serum creatinine >1.5 x ULN. Serum creatinine is 1.0-1.5 x ULN and creatinine clearance is under 60 mL/min (calculated according to Chronic Kidney Disease Epidemiology Collaboration [CKD-EP]).
• Prior isotope therapy or radiotherapy to ≥30% of bone marrow. At the first study drug administration day, patient has not elapsed 8 weeks (12 weeks for strontium-89) from the day prior isotope therapy finished.
• Prior surgery, radiation, chemotherapy, or other anticancer therapy within 4 weeks prior to enrollment in the study.
• Symptomatic peripheral neuropathy grade ≥2 (NCI CTCAE v.4.0).
• History of severe hypersensitivity reaction (grade ≥3) to polysorbate 80 containing drugs.
• Prior and other concurrent malignancy, excepted cases are as follows; basal cell carcinoma or squamous cell carcinoma of skin, or superficial (pTis, pTa, and pT1) bladder cancer (including immunotherapy) treated adequately, any other cancer completed the chemotherapy more than 5 years ago and been more than 5 years as disease free duration.
• Uncontrolled severe illness or medical condition (including uncontrolled diabetes mellitus).
• Known lesion at brain or leptomeninx.
• Known acquired immunodeficiency syndrome (AIDS-related illnesses) or known human immunodeficiency virus (HIV) disease requiring antiretroviral treatment.
• Active varicella zoster infection, anti-hepatitis C virus (HCV) antibody-positive (excluding patients negative for HCV virus in blood test or non-active seropositive patients with no hepatic abnormalities [AST, ALT, etc.]), or hepatitis B surface (HBs) antigen-positive.
• Concurrent or planned treatment with strong inhibitors or strong inducers of cytochrome P450 3A4 or 5 (wash-out period for a one week is necessary for patients who are already on these treatments or a two-week wash-out period is necessary for patients who are already on these treatments).
• Contraindication to be used corticosteroid.
• Patients with reproductive potential who do not agree to use an accepted and effective method of contraception during the study treatment period. The definition of "effective method of contraception" will be based on the Investigator's judgment.
• Participation in another clinical trial and any concurrent treatment with any investigational drug within 30 days prior to registration.
• Prior history of severe hypersensitivity reaction (≥grade 3) or intolerance to prednisolone, PEG-G-CSF or G-CSF.
• Known hypersensitivity to the component of PEG-G-CSF and/or G-CSF.
• Myelogenous leukemia insufficient decrease of the number of blast in bone marrow, or found myeloblast in peripheral blood.
