Dette er et multicenter randomiseret, dobbeltblindt, placebokontrolleret, parallelt 4-armsstudie.

Efter at have mødt berettigelse i screeningsperioden, vil forsøgspersoner blive randomiseret (1:1:1:1) til en af ​​fire behandlingsarme.

  • Arm 1: Placebo
  • Arm 2: 27 mg Dosisarm
  • Arm 3: 54 mg Dosisarm
  • Arm 4: 108 mg dosisarm Hver arm vil blive titreret til deres faste dosis i løbet af den blindede 2-ugers titreringsperiode efterfulgt af den 4-ugers faste dosisperiode i i alt 6 uger på lægemidlet.

Detaljeret beskrivelse

Dette er et multicenter randomiseret, dobbeltblindt, placebokontrolleret, parallelt 4-armsstudie.

Efter at have mødt berettigelse i screeningsperioden, vil forsøgspersoner blive randomiseret (1:1:1:1) til en af ​​fire behandlingsarme.

  • Arm 1: Placebo
  • Arm 2: 27 mg Dosisarm
  • Arm 3: 54 mg Dosisarm
  • Arm 4: 108 mg dosisarm Hver arm vil blive titreret til deres faste dosis i løbet af den blindede 2-ugers titreringsperiode i henhold til tabel: Doseringsskema, efterfulgt af den 4-ugers faste dosisperiode i i alt 6 uger på lægemidlet.

Forsøgspersonerne vil blive taget fra studielægemidlet i slutningen af ​​den faste dosisperiode og fulgt efter behandlingen i yderligere 2 uger.

Hvis der sker permanent seponering af forsøgsproduktet på noget tidspunkt, skal forsøgspersonen vende tilbage til seponering og sikkerhedsopfølgningsbesøg. De vil derefter blive kontaktet telefonisk i uge 6 for at indsamle oplysninger om alvorlige bivirkninger (SAE) og vital status.

Et uafhængigt Data Safety Monitoring Board (DSMB) vil med jævne mellemrum gennemgå udvalgte data.

Change From Baseline in Leicester Cough Questionnaire (LCQ) Total Score at Week 6
Tidsramme: 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.
