NCT02452008

Brief Summary

The primary objective of this study is to compare the progression free survival (PFS) of patients with metastatic castration-resistant prostate cancer treated with enzalutamide in combination with LY2157299 (Arm 1) versus enzalutamide alone (Arm 2).

Outcome Measures

Primary Outcomes (1)

  • Progression free survival in patients with metastatic castration-resistant prostate cancer treated with enzalutamide and LY2157299 (Arm 1) versus enzalutamide alone (Arm 2) using RECIST 1.1 criteria.

    4 years

Secondary Outcomes (3)

  • Tumor marker kinetics (PSA) in patients with metastatic castration-resistant prostate cancer treated with enzalutamide and LY2157299 (Arm 1) versus enzalutamide alone (Arm 2).

    4 years

  • Overall survival (OS) in patients with metastatic castration-resistant prostate cancer treated with enzalutamide and LY2157299 (Arm 1) versus enzalutamide alone (Arm 2).

    4 years

  • Number of patients experiencing treatment-related toxicities

    4 years

Eligibility Criteria

Age18 Years - 100 Years
Sexmale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Have metastatic castration-resistant prostate cancer
  • Must have had prior abiraterone treatment
  • Life expectancy of greater than 3 months
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 2
  • Age ≥18 years
  • Have measurable disease
  • Patients acceptance to have a tumor biopsy of an accessible lesion at baseline and on treatment if the lesion can be biopsied with acceptable clinical risk (as judged by the investigator).
  • Ability to take oral medication
  • Patients must have adequate organ and marrow function defined by study-specified laboratory tests
  • Must use acceptable form of birth control while on study
  • Ability to understand and willingness to sign a written informed consent document

You may not qualify if:

  • Prior chemotherapy for metastatic disease in castration-resistant prostate cancer
  • Had surgery within 4 weeks prior to the first dose of study drug
  • Had radiation, biological, or other investigational cancer therapy within 2 weeks prior to the first dose of study drug

  • Systemic steroids within 1 weeks prior to the first dose of study drug
  • Had prior enzalutamide, ARN-509, or galeterone therapy
  • Have moderate or severe cardiovascular disease
  • Have a history of a seizure
  • Have uncontrolled intercurrent illness, including but not limited to ongoing or active infection, systematic congestive heart failure, unstable angina pectoris, cardiac arrhythmia or psychiatric condition that would limit compliance with study requirements
  • Have a history of any autoimmune disease:inflammatory bowel disease, (including ulcerative colitis and Crohn's Disease), rheumatoid arthritis, systemic progressive sclerosis (scleroderma), systemic lupus erythmatosus (SLE) autoimmune vasculitis (e.g., Wegener's Granulomatosis), central nervous system (CNS) or motor neuropathy considered to be of autoimmune origin (e.g., Guillian-Barre Syndrome, Myasthenia Gravis, Multiple Sclerosis)
  • Have known history of infection with HIV, hepatitis B, or hepatitis C
