Remission & chronicity

Spontaneous remission

Without treatment, median survival from diagnosis 2.8 years (pre-modern-therapy era); with current therapy 5-year survival ~50-60%; spontaneous remission essentially unknown

Best-intervention remission

Triple upfront combination therapy (ambrisentan + tadalafil + selexipag): 41% reduction in clinical failure events (TRITON trial); macitentan + tadalafil initial combination: 41% risk reduction (AMBITION); lung transplantation: 50-60% 5-year survival

Drug-free remission

—

Relapse after remission

—

Chronicity

—

Gap size

Large — most patients still receive sequential monotherapy or dual therapy rather than upfront triple therapy

Primary barrier

practice/access

Barrier detail: Upfront combination therapy evidence is robust but drug costs (selexipag alone ~$150K/year) limit access; PAH is often missed or delayed in diagnosis (mean 2-year diagnostic delay); most patients are not treated at PAH expert centres where combination protocols are standard

Last SoC change: 2024 — sotatercept (Winrevair, activin signalling inhibitor) FDA approved — first new mechanism in 15 years; 2017 selexipag approved; upfront dual combination established 2015 (AMBITION); prostacyclin pathway drugs since 1995 (epoprostenol)
