Pitolisant to Assess Weekly Frequency of Cataplexy Attacks and EDS in Narcoleptic Patients (HARMONY CTP)

A Phase 3 interventional study of Pitolisant and Placebo in Narcolepsy With Cataplexy and Excessive Daytime Sleepiness, sponsored by Bioprojet. Completed at 1 site in Hungary. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2016-08-31.

Primary conditionCataplexyRegistry: NarcolepsyReclassifiedWhy we changed it
Registry
Narcolepsy — the first condition term the registry derived for this study.
ClinicalTrials.gg
Cataplexy
Why
  1. The study's listed conditions name Cataplexy, a narrower term within Narcolepsy.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

Double blind, randomized, parallel groups study of Pitolisant versus placebo, in narcoleptic patients experiencing EDS, and cataplexy (minimum of 3 complete or partial cataplexy attacks per week).

The patients will be treated during 7 weeks with Pitolisant or placebo.

Read the detailed description

The treatment period (7 weeks double blind) will aim at demonstrating the efficacy of Pitolisant on the number of cataplexy attacks and the Excessive Daytime Sleepiness by verifying whether the results of Pitolisant are superior to those of placebo.

The safety will also be assessed.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 31, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
