NCT01077284

Brief Summary

The purpose of this study is to determine the efficacy of febuxostat, once daily (QD), compared to allopurinol or placebo in patients with excessive amounts of uric acid in their urine and who have recently had kidney stones.

Outcome Measures

Primary Outcomes (1)

  • Percent Change From Baseline to Month 6 in 24-hour Urine Uric Acid (uUA) Excretion

    The change from Baseline to Month 6 in 24-hour urine uric acid is expressed as a percentage of the Baseline uUA value.

    Baseline and Month 6

Secondary Outcomes (3)

  • Percent Change From Baseline to Month 6 in the In-plane Diameter of the Largest Calcium Oxalate (CaOx) Stone

    Baseline and Month 6

  • Change From Baseline to Month 6 in the Number of Calcium Oxalate Stones

    Baseline and Month 6

  • Change From Baseline to Month 6 in 24-hour Measured Creatinine Clearance

    Baseline and Month 6

Study Arms (3)

Febuxostat

EXPERIMENTAL

Febuxostat 80 mg, capsules, orally, once daily for up to 6 months.

Drug: Febuxostat

Allopurinol

ACTIVE COMPARATOR

Allopurinol 200mg or 300mg (determined by kidney function), capsules, orally, once daily for up to 6 months.

Drug: Allopurinol

Placebo

PLACEBO COMPARATOR

Placebo-matching capsules, orally, once daily for up to 6 months.

Drug: Placebo

Interventions

Febuxostat capsules

Also known as: Uloric, TMX-67

Eligibility Criteria

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

You may qualify if:

  • Has hyperuricosuria, defined as a daily urine uric acid excretion greater than 700 mg as measured by 24-hour urine collection prior to randomization.
  • Has at least one calcium oxalate stone greater than or equal to 3 mm in its longest in-plane diameter, identified by Multiple Detector Computated Tomography prior to randomization.
  • Has a recent (within the previous 5 years) history of renal stones prior to screening.

You may not qualify if:

  • Has gout, secondary hyperuricemia or has experienced a gout flare.
  • Has a history of xanthinuria.
  • Has received allopurinol or probenecid within 2 years prior to randomization.
  • Has received febuxostat.
  • Has alanine aminotransferase and/or aspartate aminotransferase values greater than 2.0 times the upper limit of normal at the Screening Visit.
  • Has an abnormal serum calcium level at the Screening Visit.
  • Has a significant medical condition and/or conditions that would interfere with the treatment, safety or compliance with the protocol according to the judgment of the Investigator.
  • Has a history of drug abuse or a history of alcohol abuse within 5 years prior to the Screening Visit.
  • Participant's measured creatinine clearance is less than 30 mL/min at the Screening Visit.
  • Has hypercalciuria at Screening, while on a regular unrestricted diet, defined as urinary excretion of:
  • greater than 250 mg of calcium/24-hour for females of body weight less than 62.5 kg; OR
  • greater than 300 mg calcium/24-hour for males of body weight less than 75 kg; OR
  • greater than 4 mg calcium/kg/24-hour for males of body weight greater than or equal 75 kg and females of body weight greater than or equal 62.5 kg.
  • EXCLUDED MEDICATIONS:
  • Febuxostat, allopurinol, probenecid.
