Detaljert beskrivelse
Rett hjertestørrelse og funksjon er av største prognostisk betydning ved PAH/CTEPH. RV-ytelse målt ved ekkokardiografi og forstørret RA-område har vist seg å være uavhengige prognostiske faktorer ved PAH. Nylig har en retrospektiv studie med enkeltsenter vist at behandling med riociguat var assosiert med en signifikant reduksjon av RV- og RA-området etter 3, 6 og 12 måneder sammenlignet med baseline. RA-området ble signifikant redusert etter 12 måneder og RV systolisk funksjon vurdert med trikuspidal ringformet plan systolisk ekskursjon (TAPSE) forbedret etter 6 og 12 måneder med riociguat-terapi. Resultatene ble bekreftet av en nylig retrospektiv multisenterstudie. Det er derfor rimelig å anta en gunstig effekt av riociguat på høyre hjertestørrelse og funksjon.
Det primære effektendepunktet i denne studien er endringen i RV- og RA-området fra baseline til 24 uker. Behandlingen vil bli initiert og individuelt tilpasset i henhold til systolisk blodtrykk og toleranse. Pasienter som avbryter medisinering for tidlig vil bli bedt om å fortsette med studievurderinger og gjennomføre studiebesøk som beskrevet i protokollen.
Medisinske undersøkelser omfatter sykehistorie, fysisk undersøkelse, elektrokardiogram (EKG), blodgassanalyser, lungefunksjonstester, laboratorietesting (inkludert NT-proBNP), ekkokardiografi i hvile og høyre hjertekateterisering (RHC) i henhold til klinisk praksis ved PH-senteret .
Den prospektive perioden for datainnsamling omfatter en 24-ukers studieperiode, en oppfølgingsfase på ca. 30±7 dager.
Utfall (overlevelse og transplantasjonsfri overlevelse) for alle pasienter vil bli vurdert når siste pasient har avsluttet sin 24 ukers observasjonsperiode.

Beskrivelse
Inklusjonskriterier:
- ≥18 år på tidspunktet for inkludering.
- Mannlige og kvinnelige pasienter med symptomatisk PAH med et gjennomsnittlig lungearterietrykk (mPAP) >20 mmHg og pulmonal vaskulær motstand (PVR) ≥2 Wood Units (WU), pulmonalt arterielt kiletrykk (PAWP) ≤15 mmHg (Gruppe I / Nice Clinical) Klassifisering av pulmonal hypertensjon) eller CTEPH (Group IV / Nice Clinical Classification of Pulmonal Hypertension) definert som inoperabel målt minst 3 måneder etter start av full antikoagulasjon og mPAP >20 mmHg og PVR ≥2 WU, PAWP ≤15 mmHg; eller med vedvarende eller tilbakevendende PH etter pulmonal endarterektomi (mPAP >20 mmHg og PVR ≥2 WU, PAWP ≤15 mmHg målt minst 6 måneder etter operasjonen (iht. til Simonneau et al. 2018).
- Behandlingsnaive pasienter (med hensyn til PAH-spesifikke medisiner) og pasienter som er forhåndsbehandlet med en endotelinreseptorantagonist eller en prostacyklinanalog, forhåndsbehandlet i 2 måneder før screening maksimalt (i henhold til forhåndskombinasjonsbehandling).*
- *Forhåndsbehandlede pasienter må være stabile på endotelinreseptorantagonister eller prostacyklinbehandling i minst to uker før besøk 1. "Stabil" er definert som ingen endring i typen endotelinreseptorantagonister eller prostacyklinanalog og den respektive daglige dosen.
- En pasient kan også bli innrullert dersom en vedvarende fosfodiesterase type 5 (PDE-5) hemmerbehandling (forhåndsbehandlet i 2 måneder før screening maksimalt) med eller uten kombinasjonsbehandling med en endotelinreseptorantagonist eller prostacyklinanalog skal byttes til riociguat etter klinisk indikasjon, spesielt når pasientens risikoprofil forble i middels risikogruppe til tross for adekvat initial behandling inkludert PDE5i (definert som minst 3 av følgende parametere: kliniske tegn på progresjon, vedvarende WHO-FC III, 6MWD mellom 165 -440m, topp V02 11-15ml/min/kg (35-65% predikert), NTproBNP 300-1400 ng/l, RA-areal 18-26cm2,RAP 8-14mmHg, CI 2,0-2,4 l/ min) eller ved PDE5i-intoleranse. Enhver beslutning om å bytte vil bli tatt av klinikerne ved et vanlig klinisk oppfølgingsbesøk.
- Uspesifikke behandlinger som også kan brukes til behandling av PH som orale antikoagulantia, diuretika, digitalis, kalsiumkanalblokkere eller oksygentilskudd er tillatt. Imidlertid må behandling med antikoagulantia (hvis indisert) være startet minst 1 måned før besøk hos pasienter med PAH 1.
- RHC-resultater må ikke være eldre enn 6 måneder ved screening (vil bli vurdert som baseline-verdier) og må ha blitt målt i det deltakende senteret under standardiserte forhold (se den studiespesifikke Swan Ganz-kateteriseringsmanualen). Hvis de respektive målingene ikke er utført i sammenheng med pasientens vanlige diagnostiske opparbeidelse, må de utføres som en del av studien under forstudiefasen (etter at pasienten har signert det informerte samtykket).
- Kvinner uten fruktbarhet definert som postmenopausale kvinner i alderen 50 år eller eldre, kvinner med bilateral tubal ligering, kvinner med bilateral ovariektomi og kvinner med hysterektomi kan inkluderes i studien.

Negativ serumgraviditetstest ved Screening og negativ uringraviditetstest ved studiestart (besøk 1). b. Avtale om å foreta månedlige uringraviditetstester under studien og inntil minst 30 dager etter avsluttet studiebehandling. Disse testene bør utføres av pasienten hjemme. c. Enighet om å følge prevensjonsordningen som spesifisert fra Screening til minst 30 dager etter avsluttet studiebehandling.
- Pasienter som er i stand til å forstå og følge instruksjoner og som er i stand til å delta i studien i hele perioden.
- Pasienter må ha gitt sitt skriftlige informerte samtykke til å delta i studien etter å ha mottatt tilstrekkelig tidligere informasjon og før eventuelle studiespesifikke prosedyrer.
Ekskluderingskriterier:
- Gravide kvinner, eller ammende kvinner, eller kvinner i fertil alder som ikke er i stand til eller villige til å overholde studiepålagte prevensjonsmetoder spesifisert ovenfor.
- Pasienter med PH-spesifikk behandling <2 måneder før screening.
- Pasienter med en medisinsk lidelse, tilstand eller historie som vil svekke pasientens evne til å delta eller fullføre denne studien etter etterforskerens oppfatning.
- Pasienter med underliggende medisinske lidelser med forventet levealder under 2 år (f. aktiv kreftsykdom med lokalisert og/eller metastasert tumormasse).
- Pasienter med en historie med alvorlige eller flere medikamentallergier
- Pasienter med overfølsomhet overfor undersøkelsesstoffet eller noen av hjelpestoffene.
- Pasienter som ikke kan utføre en gyldig 6MWD-test (f. ortopedisk sykdom, perifer arterieokklusiv sykdom, som påvirker pasientens evne til å gå).

Annen: Riociguat
Riociguat (1 mg, 1,5 mg, 2 mg og 2,5 mg tre ganger daglig) starter med 1,0 mg tre ganger daglig i begynnelsen av studien.
Doseringen vil bli opptitrert individuelt opp til en maksimal dose på 2,5 mg tre ganger daglig etter 8 uker.
Studiemedisin vil bli gitt oralt med eller uten mat.
Tabletter bør tas tre ganger daglig med ca. 6 til 8 timers mellomrom.
|
Behandlingen vil bli initiert og individuelt tilpasset i henhold til systolisk blodtrykk og toleranse.
I titreringsfasen vil hver pasient bli bedt om å måle sitt perifere systoliske blodtrykk og hjertefrekvens hjemme tre ganger per dag og dokumentere verdiene i pasientdagboken.
Resultatene vil bli undersøkt av etterforskeren under hvert besøk/telefonbesøk.
Forutsatt at det systoliske blodtrykket er ≥ 95 mmHg målt ved bunnen før inntak av hver dose og pasienten ikke har tegn eller symptomer på hypotensjon, vil dosen av studiemedisinen titreres med +0,5 mg tid hver 2. uke frem til maksimal tolerert dose ( maksimal tillatt dose: 2,5 mg tid).
Etter titreringsperioden bør blodtrykket måles ved tegn eller symptomer på hypotensjon.
Vedlikeholdsdose: Den etablerte individuelle dosen bør opprettholdes med mindre tegn og symptomer på hypotensjon oppstår.

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.
