NCT01323855

Brief Summary

This is a two part study to compare the PK of preladenant administered to participants with CRI to the PK of preladenant administered to healthy participants. Part 1 will compare the PK of participants with severe CRI to healthy participants. Part 2 will compare the PK of participants with moderate CRI and participants with mild CRI to healthy participants. The primary hypotheses are that the plasma area under the concentration-time curve from time 0 to infinity after single dosing (AUC0-∞) of preladenant in participants with either severe, moderate or mild CRI is similar to that of matched healthy participants.

Outcome Measures

Primary Outcomes (3)

  • Area Under the Concentration-time Curve From Time 0 to Infinity (AUC0-∞) After Single Dosing With Preladenant for Participants With Severe CRI Versus Healthy Matched Controls

    Blood samples were taken at the following timepoints: pre-dose, 0.25, 0.50, 0.75, 1, 2, 4, 6, 12, 16, 24, 30, 36 and 48 hours postdose in order to determine the AUC0-∞ of preladenant

    Pre-dose to 48 hours post-dose

  • AUC0-∞ After Single Dosing With Preladenant for Participants With Moderate CRI Versus Healthy Matched Controls

    Blood samples were taken at the following timepoints: pre-dose, 0.25, 0.50, 0.75, 1, 2, 4, 6, 12, 16, 24, 30, 36 and 48 hours postdose in order to determine the AUC0-∞ of preladenant

    Pre-dose to 48 hours post-dose

  • AUC0-∞ After Single Dosing With Preladenant for Participants With Mild CRI Versus Healthy Matched Controls

    Blood samples were taken at the following timepoints: pre-dose, 0.25, 0.50, 0.75, 1, 2, 4, 6, 12, 16, 24, 30, 36 and 48 hours postdose in order to determine the AUC0-∞ of preladenant

    Pre-dose to 48 hours post-dose

Study Arms (5)

Part 1: Severe Renal Impairment

EXPERIMENTAL

Participants with severe CRI, defined as creatinine clearance of \<30 mL/min/1.73 m\^2, were treated with a single tablet of 5 mg preladenant, administered orally

Drug: Preladenant

Part 2: Moderate Renal Impairment

EXPERIMENTAL

Participants with moderate CRI defined as creatinine clearance of ≥30 and \<50 mL/min/1.73 m\^2, were treated with a single tablet of 5 mg preladenant, administered orally

Drug: Preladenant

Part 2: Mild Renal Impairment

EXPERIMENTAL

Participants with mild CRI, defined as creatinine clearance of ≥50 and ≤80 mL/min/1.73m\^2, were treated with a single tablet of 5 mg preladenant, administered orally

Drug: Preladenant

Part 1: Normal Renal Function

EXPERIMENTAL

Participants with normal renal function, defined as creatinine clearance of \>80 mL/min/1.73 m\^2, were treated with a single tablet of 5 mg preladenant, administered orally

Drug: Preladenant

Part 2: Normal Renal Function

EXPERIMENTAL

Participants with normal renal function, defined as creatinine clearance of \>80 mL/min/1.73 m\^2, were treated with a single tablet of 5 mg preladenant, administered orally

Drug: Preladenant

Interventions

After an overnight fast, a single 5 mg dose, (1 x 5 mg tablet) was administered orally

  • Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism or excretion of any drug
  • Had a renal transplant or are on dialysis
  • Has a history of any infectious disease within 4 weeks
  • Is positive for hepatitis B surface antigen, hepatitis C antibodies or human immunodeficiency virus (HIV)
  • Has donated blood or had a blood transfusions in the past 60 days
  • Has demonstrated allergic reactions (eg, food, drug, atopic reactions or asthmatic episodes) which could interfere with their ability to participate in the trial
  • Has a history of malignancy
  • Has evidence of suicidality or is at risk for self-harm or harm to others
