Riduzione della tosse in IPF con Nalbuphine ER (CORAL)

2 giugno 2026 aggiornato da: Trevi Therapeutics

Uno studio randomizzato, in doppio cieco, controllato con placebo, parallelo, a 4 bracci sulla sicurezza e l'efficacia delle compresse a rilascio prolungato di nalbufina (NAL ER) per il trattamento della tosse nella fibrosi polmonare idiopatica (IPF)

Questo è uno studio multicentrico randomizzato, in doppio cieco, controllato con placebo, parallelo, a 4 bracci.

Dopo aver soddisfatto l'idoneità durante il periodo di screening, i soggetti verranno randomizzati (1:1:1:1) a uno dei quattro bracci di trattamento.

  • Braccio 1: Placebo
  • Braccio 2: braccio dose 27 mg
  • Braccio 3: braccio dose 54 mg
  • Braccio 4: Braccio con dose da 108 mg Ciascun braccio verrà titolato alla dose fissa durante il periodo di titolazione di 2 settimane in cieco seguito dal periodo di somministrazione fissa di 4 settimane per un totale di 6 settimane di assunzione del farmaco.

Descrizione dettagliata

Questo è uno studio multicentrico randomizzato, in doppio cieco, controllato con placebo, parallelo, a 4 bracci.

Dopo aver soddisfatto l'idoneità durante il periodo di screening, i soggetti verranno randomizzati (1:1:1:1) a uno dei quattro bracci di trattamento.

  • Braccio 1: Placebo
  • Braccio 2: braccio dose 27 mg
  • Braccio 3: braccio dose 54 mg
  • Braccio 4: Braccio con dose da 108 mg Ogni braccio sarà titolato alla dose fissa durante il periodo di titolazione di 2 settimane in cieco secondo la Tabella: Schema di dosaggio, seguito dal periodo di somministrazione fissa di 4 settimane per un totale di 6 settimane di assunzione del farmaco.

I soggetti verranno sospesi dal farmaco in studio alla fine del periodo a dose fissa e seguiti dal trattamento per altre 2 settimane.

Se in qualsiasi momento si verifica l'interruzione permanente del prodotto sperimentale, il soggetto deve tornare per l'interruzione e le visite di follow-up sulla sicurezza. Saranno quindi contattati telefonicamente alla settimana 6 per raccogliere informazioni sugli eventi avversi gravi (SAE) e sullo stato vitale.

Un Data Safety Monitoring Board (DSMB) indipendente esaminerà periodicamente i dati selezionati.

Change From Baseline in Leicester Cough Questionnaire (LCQ) Total Score at Week 6
Lasso di tempo: Baseline, Week 6
LCQ is a self-reporting quality of life measure of chronic cough. It consists of 19 items with a 7-point Likert response scale ranging from 1 to 7. The responses are as follows: 1 = all of the time, 2 = most of the time, 3 = a good bit of the time, 4 = some of the time, 5 = a little of the time, 6 = hardly any of the time, and 7 = none of the time. Each item is designed to assess cough symptoms and the impact of cough across three main domains, physical (8 items), psychological (7 items), and social (4 items). Domain scores are calculated as the total score from items in the domain divided by the number of items in the domain and range from 1 to 7. The LCQ total score is calculated by summing the individual domain scores and ranges from 3 to 21, with higher scores indicating better health status. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

The module contains 15 items that fall into 3 domains: Dyspnea, Cough, and Energy. Each item consists of a 0-3 score range. Dyspnea consists of 7 items and has a raw sum score range of 0-21 with higher scores indicating worsening dyspnea symptoms, Cough consists of 5 items and has a raw sum score range of 0-15 with higher scores indicating worsening cough symptoms, and Energy consists of 3 items and has a raw sum score range of 0-9 with higher scores indicating worsening energy. A negative change from Baseline indicates improvement. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
