A proportion of pulmonary arterial hypertension (PAH) patients do not reach
treatment goals with phosphodiesterase-5 inhibitors (PDE5i). RESPITE investigated
the safety, feasibility and benefit of switching from PDE5i to riociguat in these
patients.RESPITE was a 24-week, open-label, multicentre, uncontrolled study.
Patients in World Health Organization (WHO) functional class (FC) III, with 6-min
walking distance (6MWD) 165-440?m, cardiac index <3.0?L·min(-1)·m(-2) and
pulmonary vascular resistance >400?dyn·s·cm(-5) underwent a 1-3?day PDE5i
treatment-free period before receiving riociguat adjusted up to 2.5?mg maximum
t.i.d Exploratory end-points included change in 6MWD, WHO FC, N-terminal
prohormone of brain natriuretic peptide (NT-proBNP) and safety.Of 61 patients
enrolled, 51 (84%) completed RESPITE. 50 (82%) were receiving concomitant
endothelin receptor antagonists. At week 24, mean±sd 6MWD had increased by
31±63?m, NT-proBNP decreased by 347±1235?pg·mL(-1) and WHO FC improved in 28
patients (54%). 32 patients (52%) experienced study drug-related adverse events
and 10 (16%) experienced serious adverse events (2 (3%) study drug-related, none
during the PDE5i treatment-free period). Six patients (10%) experienced clinical
worsening, including death in two (not study drug-related).In conclusion,
selected patients with PAH may benefit from switching from PDE5i to riociguat,
but this strategy needs to be further studied.
