Riociguat was well tolerated; 2% (n=1) of pts withdrew due to adverse events. Improvements in 6MWD at Wk 12 of CHEST-2 vs CHEST-1 baseline (ex-riociguat 40±75 m; ex-pbo 44±43 m) were sustained for 1 yr in the overall cohort (44±64 m; n=42). WHO functional class improved/stabilized/worsened in 42/53/4% and 42/58/0% of the ex-riociguat and ex-pbo pts, respectively, at Wk 12 of CHEST-2, and 49/51/0% of pts at 1 yr (n=43).ConclusionsLong-term riociguat was well tolerated in pts with persistent/recurrent PH following PEA and improved 6MWD and secondary endpoints for up to 1 yr.
