Study summary

The purpose of this study is to demonstrate the safety and effectiveness of abiraterone acetate when co-administered with prednisone in patients with chemo-naive metastatic castration resistant prostate Cancer (mCRPC).

Read the detailed description

This is a multinational, multicenter, randomized (the study drug is assigned by chance), double-blind (neither physician nor patient knows the treatment that the patient receives), placebo-controlled (an inactive substance that is compared with a drug to test whether the drug has a real effect in a clinical trial) study. All patients will be randomly assigned in a 1:1 ratio between the abiraterone acetate group (abiraterone acetate and prednisone) and the placebo group (placebo and prednisone). The study will consist of a screening phase (within 28 days prior randomization on Cycle 1, Day 1), a treatment phase (28-day cycles until disease progression), and a follow-up phase (all patients will be contacted for every 3 months up to Month 60, focusing primarily on survival status). Patients will receive either abiraterone acetate 1,000 mg daily and prednisone 5 mg twice daily or placebo and prednisone 5 mg twice daily.

Inclusion criteria

  • Has a confirmed diagnosis of adenocarcinoma of the prostate with evidence of metastatic disease
  • Prostate cancer progression documented by PSA progression or radiographic progression
  • Asymptomatic or mildly symptomatic from prostate cancer
  • Surgically or medically castrated, with testosterone levels of \<50 ng/dL
  • Previous anti-androgen therapy and progression after withdrawal
  • ECOG performance status score of 0 or 1
  • If opiate analgesics for cancer-related pain, treatment must not be administered within 4 weeks of Cycle 1 Day 1
  • If radiation therapy for treatment of the primary tumor is given, treatment must not be administered within 6 weeks of Cycle 1 Day 1
  • If previously treated with ketoconazole for prostate cancer, duration of treatment must not be greater than 7 days

Exclusion criteria

Exclusion Criteria:

  • Active infection or other medical condition that would make prednisone (corticosteroid) use contraindicated
  • Any chronic medical condition requiring a higher dose of corticosteroid than 5 mg prednisone twice daily

  • Liver or visceral organ metastasis, brain metastasis, and other malignancy, except non-melanoma skin cancer, with a 30% probability of recurrence within 24 months
  • Prior cytotoxic chemotherapy or biologic therapy for the treatment of metastatic castration-resistant prostate cancer (mCRPC)
  • Radiation or radionuclide therapy for treatment of mCRPC
  • Uncontrolled hypertension, patients with a history of hypertension are allowed provided blood pressure is controlled by anti hypertensive treatment

What researchers measure

Primary outcomes

  1. Time to prostate specific antigen (PSA) progression (TTPP)

    Measured from the time interval from the date of randomization to the date of the PSA progression based on prostate cancer clinical trials working group 2 (PCWG2) criteria

    Time frame: 14 months

Secondary outcomes

  1. Overall survival

    The percentage of people in a study or treatment group who are alive from date of randomization to date of death

    Time frame: 5 years

  2. Time to initiation of cytotoxic chemotherapy

    Date of randomization to date of initiation of chemotherapy

    Time frame: 5 years

  3. Prostate specific antigen (PSA) response rate

    Proportion of patients achieving a PSA decline 50% according to prostate cancer clinical trials working group 2 (PCWG2) criteria

    Time frame: 14 months

  4. Objective response rate

    Measurable disease based on modified response evaluation criteria in solid tumors (RECIST) criteria and baseline lymph node size must be 2.0 cm to be considered target or evaluable lesion for RECIST criteria

    Time frame: 14 months

  5. Quality of life (QoL) total score and each subscale score

    Assessed by functional assessment of cancer therapy-prostate (FACT-P)

    Time frame: 14 months

  6. Time to pain progression

    Assessed by the Brief Pain Inventory Short Form (BPI-SF) and analgesic score

    Time frame: 14 months

  7. Time to Eastern Cooperative Oncology Group (ECOG) performance status score determination

    ECOG performance status score 0 (Fully active, able to carry on all pre-disease performance without restriction) versus 1 (Restricted in physically strenuous activity but ambulatory and able to carry out work on a light or sedentary nature, eg, light housework, office work)

    Time frame: 14 months

  8. Collection of safety data including adverse events

    Time frame: 5 years
