Detaljeret beskrivelse
Den rigtige hjertestørrelse og funktion er af største prognostisk betydning ved PAH/CTEPH. RV-ydelse målt ved ekkokardiografi og forstørret RA-område har vist sig at være uafhængige prognostiske faktorer i PAH. For nylig har et retrospektivt enkeltcenterstudie vist, at behandling med riociguat var forbundet med en signifikant reduktion af RV- og RA-området efter 3, 6 og 12 måneder sammenlignet med baseline. RA-areal faldt signifikant efter 12 måneder, og RV-systolisk funktion vurderet med tricuspid ringformet systolisk ekskursion (TAPSE) blev forbedret efter 6 og 12 måneders riociguat-behandling. Resultaterne blev bekræftet af en nylig retrospektiv multicenterundersøgelse. Det er derfor rimeligt at antage en gavnlig effekt af riociguat på højre hjertestørrelse og funktion.
Det primære effektmål i denne undersøgelse er ændringen i RV- og RA-området fra baseline til 24 uger. Behandlingen vil blive påbegyndt og individuelt tilpasset efter systolisk blodtryk og tolerabilitet. Patienter, der ophører med medicin for tidligt, vil blive bedt om at fortsætte med undersøgelsesvurderinger og udføre undersøgelsesbesøg som beskrevet i protokollen.
Lægeundersøgelser omfatter sygehistorie, fysisk undersøgelse, elektrokardiogram (EKG), blodgasanalyser, lungefunktionstests, laboratorieundersøgelser (inklusive NT-proBNP), ekkokardiografi i hvile og højre hjertekateterisering (RHC) i henhold til klinisk praksis på PH-centret .
Den prospektive periode for dataindsamling omfatter en 24-ugers undersøgelsesperiode, en opfølgningsfase på ca. 30±7 dage.
Resultatet (overlevelse og transplantationsfri overlevelse) for alle patienter vil blive vurderet, når den sidste patient har afsluttet sin 24-ugers observationsperiode.

Beskrivelse
Inklusionskriterier:
- ≥18 år på tidspunktet for optagelse.
- Mandlige og kvindelige patienter med symptomatisk PAH med et gennemsnitligt pulmonalt arterietryk (mPAP) >20 mmHg og pulmonal vaskulær modstand (PVR) ≥2 Wood Units (WU), pulmonalt arterielt kiletryk (PAWP) ≤15 mmHg (Gruppe I / Nice Clinical Klassifikation af pulmonal hypertension) eller CTEPH (Group IV / Nice Clinical Classification of Pulmonal Hypertension) defineret som inoperabel målt mindst 3 måneder efter start af fuld antikoagulering og mPAP >20 mmHg og PVR ≥2 WU, PAWP ≤15 mmHg; eller med vedvarende eller tilbagevendende PH efter pulmonal endarterektomi (mPAP >20 mmHg og PVR ≥2 WU, PAWP ≤15 mmHg målt mindst 6 måneder efter operationen (iht. til Simonneau et al. 2018).
- Behandlingsnaive patienter (med hensyn til PAH-specifik medicin) og patienter, der er forbehandlet med en endotelinreceptorantagonist eller en prostacyclinanalog, forbehandlet i højst 2 måneder før screening (ifølge forudgående kombinationsbehandling).*
- *Forbehandlede patienter skal være stabile på endotelinreceptorantagonister eller prostacyclinbehandling i mindst to uger før besøg 1. "Stabil" defineres som ingen ændring i typen af endotelinreceptorantagonister eller prostacyclinanalog og den respektive daglige dosis.
- En patient kan også indskrives, hvis en vedvarende phosphodiesterase type 5 (PDE-5) hæmmerbehandling (forbehandlet i højst 2 måneder før screening) med eller uden kombinationsbehandling med en endotelinreceptorantagonist eller prostacyclinanalog skal skiftes til riociguat efter klinisk indikation, især når patientens risikoprofil forblev i den mellemliggende risikogruppe på trods af tilstrækkelig initial behandling inklusive PDE5i (defineret som mindst 3 af følgende parametre: kliniske tegn på progression, vedvarende WHO-FC III, 6MWD mellem 165 -440m, peak V02 11-15ml/min/kg (35-65% forudsagt), NTproBNP 300-1400 ng/l, RA-areal 18-26cm2,RAP 8-14mmHg, CI 2,0-2,4 l/ min) eller i tilfælde af PDE5i-intolerance. Enhver beslutning om at skifte vil blive truffet af klinikerne ved et regelmæssigt klinisk opfølgningsbesøg.
- Uspecifikke behandlinger, som også kan anvendes til behandling af PH, såsom orale antikoagulantia, diuretika, digitalis, calciumkanalblokkere eller ilttilskud er tilladt. Behandling med antikoagulantia (hvis indiceret) skal dog være startet mindst 1 måned før besøg hos patienter med PAH 1.
- RHC-resultater må ikke være ældre end 6 måneder ved screening (vil blive betragtet som baseline-værdier) og skal være målt i det deltagende center under standardiserede forhold (se den undersøgelsesspecifikke Swan Ganz-kateteriseringsmanual). Hvis de respektive målinger ikke er blevet udført i forbindelse med patientens regelmæssige diagnostiske oparbejdning, skal de udføres som en del af undersøgelsen i forundersøgelsesfasen (efter at patienten har underskrevet det informerede samtykke).
- Kvinder uden den fødedygtige alder defineret som postmenopausale kvinder i alderen 50 år eller ældre, kvinder med bilateral tubal ligering, kvinder med bilateral ovariektomi og kvinder med hysterektomi kan inkluderes i undersøgelsen.

Aftale om at følge præventionsordningen som specificeret fra screening indtil mindst 30 dage efter seponering af undersøgelsesbehandling.
- Patienter, der er i stand til at forstå og følge instruktioner, og som er i stand til at deltage i undersøgelsen i hele perioden.
- Patienter skal have givet deres skriftlige informerede samtykke til at deltage i undersøgelsen efter at have modtaget tilstrækkelig forudgående information og forud for eventuelle undersøgelsesspecifikke procedurer.
Ekskluderingskriterier:
- Gravide kvinder eller ammende kvinder eller kvinder i den fødedygtige alder, der ikke er i stand til eller villige til at overholde undersøgelsespligtige præventionsmetoder specificeret ovenfor.
- Patienter med PH-specifik behandling <2 måneder før screening.
- Patienter med en medicinsk lidelse, tilstand eller en sådan historie, som ville forringe patientens evne til at deltage eller fuldføre denne undersøgelse efter investigatorens mening.
- Patienter med underliggende medicinske lidelser med en forventet levetid på under 2 år (f. aktiv kræftsygdom med lokaliseret og/eller metastaseret tumormasse).
- Patienter med en historie med alvorlige eller flere lægemiddelallergier
- Patienter med overfølsomhed over for forsøgslægemidlet eller et eller flere af hjælpestofferne.

- Parenterale prostacyclinanaloger
- Specifikke phosphodiesterasehæmmere (f. sildenafil eller tadalafil): kan skiftes til riociguat, men ikke gives som supplement til undersøgelseslægemidlet
- eller uspecifikke phosphodiesterasehæmmere (f. dipyridamol, theophyllin)
- INGEN donorer (f.eks. nitrater)

Andet: Riociguat
Riociguat (1 mg, 1,5 mg, 2 mg og 2,5 mg tre gange dagligt) startende med 1,0 mg tre gange dagligt i begyndelsen af undersøgelsen.
Dosis optitreres individuelt op til en maksimal dosis på 2,5 mg tre gange dagligt efter 8 uger.
Studiemedicin vil blive givet oralt med eller uden mad.
Tabletter bør tages tre gange dagligt med cirka 6 til 8 timers mellemrum.
|
Behandlingen vil blive påbegyndt og individuelt tilpasset efter systolisk blodtryk og tolerabilitet.
I titreringsfasen vil hver patient blive bedt om at måle sit perifere systoliske blodtryk og hjertefrekvensen hjemme tre gange dagligt og dokumentere værdierne i patientens dagbog.
Resultaterne vil blive undersøgt af investigator under hvert besøg/telefonopkald-besøg.
Forudsat at det systoliske blodtryk er ≥ 95 mmHg målt ved lavpunkt før indtagelse af hver dosis, og patienten ikke har tegn eller symptomer på hypotension, vil dosis af undersøgelsesmedicin blive titreret med +0,5 mg tid hver 2. uge indtil maksimal tolereret dosis ( maksimal tilladt dosis: på 2,5 mg tid).
Efter titreringsperioden skal blodtrykket måles ved tegn eller symptomer på hypotension.
Vedligeholdelsesdosis: Den fastsatte individuelle dosis bør opretholdes, medmindre der opstår tegn og symptomer på hypotension.

SF-36: Physical Functioning
Tidsramme: baseline to 24 weeks
|
Measure Description: Quality of Life (QoL) was assessed using the SF 36-questionnaire.
The SF-36 consists of eight scaled scores, which are the weighted sums of the questions in their section.
Each scale is directly transformed into a 0-100 scale, i.e. a score of 0 is equivalent to maximum disability and a score of 100 is equivalent to no disability.
Sections: vitality; physical functioning; bodily pain; general health perceptions; physical role functioning; emotional role functioning; social role functioning; mental health.
Two summation scores, physical and mental summation score, were calculated.
