Um Estudo Aberto, Prospectivo, de Centro Único dos Efeitos do Riociguat no Tamanho e Função do Ventrículo Direito na Hipertensão Arterial Pulmonar e Hipertensão Pulmonar Tromboembólica Crônica
Visão geral do estudo

Intervenção / Tratamento
Descrição detalhada
O tamanho e a função do coração direito são de extrema importância prognóstica na HAP/CTEPH. O desempenho do VD medido pela ecocardiografia e a área aumentada do AR têm se mostrado fatores prognósticos independentes na HAP. Recentemente, um estudo retrospectivo de centro único mostrou que o tratamento com riociguat foi associado a uma redução significativa da área de VD e AR após 3, 6 e 12 meses em comparação com a linha de base. A área do AR diminuiu significativamente após 12 meses e a função sistólica do VD avaliada com a excursão sistólica do plano anular tricúspide (TAPSE) melhorou após 6 e 12 meses de terapia com riociguat. Os resultados foram confirmados por um recente estudo multicêntrico retrospectivo. Portanto, é razoável assumir um efeito benéfico do riociguat no tamanho e na função do coração direito.
O endpoint primário de eficácia neste estudo é a mudança na área RV e RA desde o início até 24 semanas. O tratamento será iniciado e ajustado individualmente de acordo com a pressão arterial sistólica e tolerabilidade. Os pacientes que interromperem a medicação prematuramente serão solicitados a continuar com as avaliações do estudo e realizar as visitas do estudo conforme descrito no protocolo.
Os exames médicos incluem histórico médico, exame físico, eletrocardiograma (ECG), análises de gases sanguíneos, testes de função pulmonar, testes laboratoriais (incluindo NT-proBNP), ecocardiografia em repouso e cateterismo cardíaco direito (RHC) de acordo com a prática clínica do centro de PH .
O período prospectivo de coleta de dados compreende um período de estudo de 24 semanas e uma fase de acompanhamento de cerca de 30±7 dias.
O resultado (sobrevida e sobrevida livre de transplante) de todos os pacientes será avaliado quando o último paciente terminar seu período de observação de 24 semanas.

- Pacientes virgens de tratamento (com relação à medicação específica para HAP) e pacientes pré-tratados com um antagonista do receptor de endotelina ou um análogo da prostaciclina, pré-tratados por no máximo 2 meses antes da triagem (de acordo com o tratamento combinado inicial).*
- *Pacientes pré-tratados precisam estar estáveis com antagonistas dos receptores de endotelina ou tratamento com prostaciclina por pelo menos duas semanas antes da Visita 1. "Estável" é definido como nenhuma alteração no tipo de antagonista dos receptores de endotelina ou análogo de prostaciclina e a respectiva dose diária.
- Um paciente também pode ser inscrito, se um tratamento persistente com inibidor da fosfodiesterase tipo 5 (PDE-5) (pré-tratado por 2 meses antes da triagem, no máximo) com ou sem tratamento combinado com um antagonista do receptor de endotelina ou análogo de prostaciclina deve ser mudado para riociguat por indicação clínica, particularmente quando o perfil de risco do paciente permaneceu no grupo de risco intermediário, apesar do tratamento inicial adequado, incluindo PDE5i (definido como pelo menos 3 dos seguintes parâmetros: sinais clínicos de progressão, persistente WHO-FC III, 6MWD entre 165 -440m, pico de V02 11-15ml/min/kg (35-65% previsto), NTproBNP 300-1400 ng/l, área RA 18-26cm2,RAP 8-14mmHg, CI 2,0-2,4 l/ min) ou em caso de intolerância a PDE5i.

Outro: Riociguat
Riociguat (1 mg, 1,5 mg, 2 mg e 2,5 mg três vezes ao dia) começando com 1,0 mg três vezes ao dia no início do estudo.
A dosagem será aumentada individualmente até uma dosagem máxima de 2,5 mg três vezes ao dia após 8 semanas.
A medicação do estudo será fornecida por via oral com ou sem alimentos.
Os comprimidos devem ser tomados três vezes ao dia, com aproximadamente 6 a 8 horas de intervalo.
|
O tratamento será iniciado e ajustado individualmente de acordo com a pressão arterial sistólica e tolerabilidade.
Durante a fase de titulação, cada paciente será solicitado a medir sua pressão arterial sistólica periférica e a frequência cardíaca em casa três vezes ao dia e documentar os valores no diário do paciente.
Os resultados serão examinados pelo investigador durante cada visita/visita telefónica.
Desde que a pressão arterial sistólica seja ≥ 95 mmHg medida no vale antes da ingestão de cada dose e o paciente não apresente sinais ou sintomas de hipotensão, a dose da medicação do estudo será titulada em +0,5 mg três vezes ao dia a cada 2 semanas até a dosagem máxima tolerada ( dose máxima permitida: de 2,5 mg três vezes ao dia).
Após o período de titulação, a pressão arterial deve ser medida mediante sinais ou sintomas de hipotensão.
Dose de manutenção: A dose individual estabelecida deve ser mantida a menos que ocorram sinais e sintomas de hipotensão.

SF-36: Physical Functioning
Prazo: 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.
