Pfizer
ClinicalTrials.gov Identifier:
NCT01006122

  Purpose

Histaminergic agents are known to be involved with the sleep/wake cycle. This compound is a histaminergic agent which therefore may improve alertness and awakeness in patients with excessive daytime sleepiness (EDS) associated with narcolepsy. Significant improvement in EDS when treated with this compound compared to placebo in patients with narcolepsy is hypothesized.

  • Vital signs, safety labs [ Time Frame: screening, baseline, each study visit ] [ Designated as safety issue: Yes ]
  • Electrocardiogram (ECG) [ Time Frame: screening, baseline, end of each stable dosing phase ] [ Designated as safety issue: Yes ]
  • Sheehan Suicidality Tracking Scale (STS) [ Time Frame: screening, baseline and each study visit ] [ Designated as safety issue: Yes ]
  • Adverse Event logs [ Time Frame: baseline and each study visit ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Change from Baseline on the Epworth Sleepiness Scale (ESS) at the end of each Titration Phase and after 3 weeks of stable treatment [ Time Frame: screening, baseline and each study visit ] [ Designated as safety issue: No ]
  • Medical Outcomes Study (MOS) Sleep Scale [ Time Frame: baseline and each day of the study ] [ Designated as safety issue: No ]
  • Change from Baseline as measured by the SF-36 (Short-form Health Survey-36): Quality of LIfe scale [ Time Frame: baseline and end of each stable dosing phase ] [ Designated as safety issue: No ]
  • Change from Baseline in cataplexy episodes based upon patient diaries (to capture cataplexy episodes) after 3 weeks of stable treatment [ Time Frame: beginning at screening and each day of the study to end ] [ Designated as safety issue: No ]
  • Clinical Global Impression of Change (CGI-I) score [ Time Frame: screening, baseline and each study visit ] [ Designated as safety issue: No ]
  • CogState (computerized cognitive test battery) composite score and individual tests scores. [ Time Frame: baseline and each study visit ] [ Designated as safety issue: No ]
  • Change from Baseline on the Brief Fatigue Inventory (BFI) at the end of each Titration Phase and after 3 weeks of stable treatment [ Time Frame: Baseline, end of each Titration Phase, and after 3 wks stable treatment ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Placebo Comparator: Placebo Drug: Placebo
Patients receiving placebo will undergo the same procedures as those receiving active treatment. Each patient will receive matching placebo tablets in a fixed dose escalation schedule beginning at 0.25 mg QD for 5 days; then up to 0.50 mg QD for another 5 days; and up to 1.0 mg QD for an additional 5 days. At the end of this fixed titration schedule, the patient will either stay at 1.0 mg; decrease to 0.5 mg or increase to 2.0 mg based upon the clinicians judgment regarding efficacy and side effects at the 1.0 dose level. The patient will then remain at the determined dose for a 3 week stable dosing period, with a 7 (-2/+ 9) day wash out and then crossover to repeat the same sequence for the second arm of the study.
Active Comparator: PF-03654746
At the end of the second arm of the study, the patient will have completed the study and have a 7-10 day follow-up visit.
Drug: PF-03654746
Each patient will receive PF-03654746 tablets in a fixed dose titration schedule beginning at 0.25 mg QD for 5 days; then up to 0.50 mg QD for another 5 days; and up to 1.0 mg QD for an additional 5 days. At the end of this fixed titration schedule, the patient will either stay at the 1.0 mg dose; decrease to 0.50 mg or increase to 2.0 mg based upon the clinician's judgement regarding efficacy and side effects at the 1.0 mg dose. The patient will remain at the determined dose for a 3 week stable dosing period.
