Effekter av Riociguat på høyre ventrikulær størrelse og funksjon i PAH og CTEPH (RIVERII)

21. mai 2026 oppdatert av: Prof. Dr. med. Ekkehard Gruenig, Heidelberg University

En åpen, prospektiv, enkeltsenterstudie av effekten av Riociguat på høyre ventrikulær størrelse og funksjon ved pulmonal arteriell hypertensjon og kronisk tromboembolisk pulmonal hypertensjon

Dette er en åpen, enkeltarmet, prospektiv klinisk studie med ett senter for å evaluere effekten av riociguat på høyre hjertestørrelse og funksjon hos pasienter med manifest PAH og CTEPH.

Studieoversikt

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:

  1. ≥18 år på tidspunktet for inkludering.
  2. 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).
  3. 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).*
  4. *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.
  5. 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.
  6. 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.
  7. 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).
  8. 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.

Enighet om å følge prevensjonsordningen som spesifisert fra Screening til minst 30 dager etter avsluttet studiebehandling.
  10. Pasienter som er i stand til å forstå og følge instruksjoner og som er i stand til å delta i studien i hele perioden.
  11. 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:

  1. 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.
  2. Pasienter med PH-spesifikk behandling <2 måneder før screening.
  3. Pasienter med en medisinsk lidelse, tilstand eller historie som vil svekke pasientens evne til å delta eller fullføre denne studien etter etterforskerens oppfatning.
  4. Pasienter med underliggende medisinske lidelser med forventet levealder under 2 år (f. aktiv kreftsykdom med lokalisert og/eller metastasert tumormasse).
  5. Pasienter med en historie med alvorlige eller flere medikamentallergier
  6. Pasienter med overfølsomhet overfor undersøkelsesstoffet eller noen av hjelpestoffene.

Intervensjon / Behandling
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.

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.
