NCT01543776

Brief Summary

This randomized phase II trial studies the best way to give abiraterone acetate in treating patients with castration-resistant prostate cancer. Abiraterone acetate is effective in treating castrate resistant prostate cancer and is taken in the fasting state. However, the body's absorption of abiraterone is increased with food intake. This study will test the whether a lower dose of abiraterone taken with food has a similar effect on prostate specific antigen (PSA) compared to full dose taken fasting.

Outcome Measures

Primary Outcomes (1)

  • Change in PSA Level

    Data were analyzed on a log scale: log(week 12) - log(baseline) = log ratio. Smaller (more negative) values indicate a better outcome.

    From baseline to 12 weeks

Secondary Outcomes (4)

  • Progression-free Survival (PFS)

    Assessed up to 3 years

  • Adrenal Androgen Production (DHEA-S)

    Cycle 4 (4 months)

  • Number of Participants With Adverse Events (AEs)

    Assessed up to 1 year

  • Peak Plasma Concentration of Abiraterone

    Up to 4 months

Study Arms (2)

Arm I (fasting)

ACTIVE COMPARATOR

Patients receive abiraterone acetate PO daily first thing in morning after an overnight fast of at least 8 hours.

Drug: abiraterone acetate

Arm II (fed)

EXPERIMENTAL

Patients receive abiraterone acetate PO daily within 30 minutes of a conventional low-fat breakfast.

Drug: abiraterone acetate

Interventions

Given PO

Also known as: CB7630, Zytiga

Eligibility Criteria

Sexmale
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Histologically or cytologically confirmed prostate cancer with progressive disease defined as either:
  • or more new lesions on bone scan or
  • Progressive disease on computed tomography (CT)/magnetic resonance imaging (MRI) according to Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria or
  • Rising prostate-specific antigen (PSA): PSA evidence for progressive prostate cancer consists of a minimum PSA level of at least 2 ng/ml, which has subsequently risen on at least 2 successive occasions, at least 2 weeks apart
  • Evidence of castration resistance defined as disease progression despite a testosterone level \< 50 ng/dL (or surgical castration)
  • Any prior therapy for castrate disease is acceptable except prior abiraterone, which is excluded; a minimum washout of 28 days for any other anticancer therapy prior to first dose of study drug is required
  • Any other radiotherapy or radionuclide require 28-day washout prior to first dose of study drug
  • Denosumab or zoledronic acid are allowed
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1
  • Total bilirubin =\< 1.5 x the upper limit of normal
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase \[SGOT\])/alanine aminotransferase (ALT) (serum glutamic pyruvate transaminase \[SGPT\]) =\< 2.5 X institutional upper limit of normal
  • Ability to understand and the willingness to sign a written informed consent document

You may not qualify if:

  • Therapy with other hormonal therapy, including any dose of megestrol acetate (Megace), finasteride (Proscar), dutasteride (Avodart), or any herbal product known to decrease PSA levels (e.g., saw palmetto and PC-SPES), or any systemic corticosteroid (other than prednisone =\< 10 mg/day) within 4 weeks prior to first dose of study drug
  • Therapy with supplements or complementary medicines/botanicals within 4 weeks of first dose of study drug is excluded with the following exceptions:
  • Conventional multivitamin supplements
  • Selenium
  • Lycopene
  • Soy supplements
  • Inability to swallow capsules or known gastrointestinal malabsorption
  • History of other malignancies, with the exception of adequately treated non-melanoma skin cancer or adequately treated superficial bladder cancer or other solid tumors curatively treated with no evidence of disease for \>= 5 years from enrollment
  • Blood pressure that is not controlled despite \> 2 oral agents (systolic blood pressure \[SBP\] \> 160 and diastolic blood pressure \[DBP\] \> 90 documented during the screening period with no subsequent blood pressure readings \< 160/100)
  • Serum potassium (K)+ \< 3.5 mmoL/L on more than one reading within the screening period
  • Serious intercurrent infections or non-malignant medical illnesses that are uncontrolled
  • Active psychiatric illness/social situations that would limit compliance with protocol requirements
  • New York Heart Association (NYHA) class II, NYHA class III, or IV congestive heart failure (any symptomatic heart failure)
  • Concurrent therapy with strong inhibitors or inducers of Cytochrome P450 (CYP)3A4 due to concerning possible drug-drug interactions with abiraterone
