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

This is a multicentric International Phase III,Long term open label study(12 months)assessing the long-term safety and efficacy of BF2.649 (Pitolisant)in the treatment of Excessive Daytime Sleepiness (EDS) in narcoleptic patients with or without cataplexy.

Read the detailed description

In narcoleptic patients, results obtained in the previous studies showed that BF2.649 reduced significantly the diurnal somnolence compared to placebo confirming its wakening effect against EDS and demonstrating its anti-cataplectic effect when administrated on an individual titration scheme established on basis of individual benefit/tolerance ratio.This long-term safety pragmatic study will provide information about long-term treatment of BF2.649, and also allow patients who satisfy of BF2.649 treatment in previous or on-going studies of Bioprojet continuing to benefit this product.This is an open-label, naturalistic pragmatic, prospective longitudinal uncontrolled, multi-centre international trial assessing the safety and effect of long-term therapy of BF2.649 in treatment of excessive daytime sleepiness in narcolepsy, on 12-month follow-up.

In context

Cataplexy Reclassified

31 studies on the registry are indexed under Cataplexy; 5 are open to participants now.

This study's enrollment of 102 is below the median of 117 across 27 interventional studies indexed under Cataplexy.

Lead sponsor

Bioprojet is the lead sponsor of 29 studies on the registry; 2 are open to participants now.

Compared within Cataplexy, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Narcolepsy. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Inclusion criteria

  • Males or females, aged 18 years old and over.
  • Patients with a diagnosis of narcolepsy according to the International Classification of Sleep Disorders (ICSD-2) criteria.
  • Patients should have complained of EDS with an ESS score at least 12 (historical assessment).
  • Patients having previously participated in and completed a Bioprojet narcolepsy study assessing BF2.649 efficacy (P05-03, P06-06, P07-03 HARMONY I or P07-07 HARMONY II, P09-15 HARMONY I bis) or narcoleptic patients complaining with EDS which in the opinion of the investigator would not be able to participate in a double blind study against placebo but who could benefit from testing a new therapy such as the BF2.649 in an open label study.

or patient receiving BF2.649(Pitolisant) under condition of"ATU nominative" according to the French law (called named temporary authorization of use approved by the Afssaps) for Excessive Daytime Sleepiness associated with narcolepsy.

Exclusion criteria

Exclusion Criteria:

  • Patients who have discontinued study treatment during the previous studies due to adverse events related to BF2.649.
  • Patients with an untreated sleep apnoea syndrome or who have any other cause of daytime sleepiness
  • Patients working in an occupation requiring variable shift work or routine night shifts.
  • Psychiatric and neurological disorders, other than narcolepsy/cataplexy, or other problem that in the investigator's opinion would preclude the patient's participation and completion of this trial or comprise reliable representation of subjective symptoms.
  • Current or recent (within one year) history of a substance abuse or dependence disorder including alcohol abuse as defined in .
  • Other active illness, including unstable cardiovascular, or neoplasic pathology which could interfere with the study conduct or counter-indicate the study treatments or place the patient at risk during the trial or compromise the study participation.
  • Known history of long syndrome, syncope or arrhythmia or any significant serious abnormality of the (e.g. recent myocardial infarction), or QTc interval strictly higher than 450 ms (electrocardiogram Bazett's corrected QT interval
  • Severe Hepatic Impairment or with Severe Renal Impairment, or with any other significant abnormality in the physical examination or clinical laboratory results.
  • Known to the tested treatment including active substance and .
  • Participation in an other study - in the 30 days prior to the entry in this study
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

DSM diagnostic criteria

The American Psychiatric Association’s manual of mental health diagnoses. DSM-5 (2013, revised as DSM-5-TR in 2022) replaced DSM-IV, and some studies still name the older edition. “Meets DSM criteria for …” means diagnosed by that edition’s diagnostic criteria, usually by a clinician in an interview.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

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 Jan 31, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
