The efficacy and safety of UPTRAVI® were investigated in the GRIPHON trial, the largest outcomes trial conducted in pulmonary arterial hypertension (PAH) to date.[1][2]
The GRIPHON trial was a multicentre, double-blind, randomised, parallel-group, placebo-controlled, event-driven Phase 3 trial that assessed the safety and efficacy of UPTRAVI® across a broad range of patients with PAH. UPTRAVI® efficacy was demonstrated using a composite long-term outcomes primary endpoint that included PAH-related hospitalisation, disease progression events and death.[1]

*Includes patients in WHO FC I (0.8%) and FC IV (1%).[1]
‡Other aetiologies included drug- or toxin-induced PAH (2%) and HIV-PAH (1%).[1]

#Risk status was based on REVEAL 2.0 score: low risk ≤6; intermediate risk 7–8; high risk ≥9.[4]
Evidence for the long-term efficacy of UPTRAVI® is based on GRIPHON primary endpoint data, showing a significant reduction in the risk of disease progression vs placebo in patients with PAH.[1]
In the GRIPHON trial, UPTRAVI® significantly reduced the risk of disease progression by 40% vs placebo.[1]

UPTRAVI® is the only oral prostacyclin pathway agent proven to reduce PAH-related hospitalisation risk vs placebo.*[5]

*Given that additional PAH treatment was initiated in a small proportion of patients and that there was no control group in the extension study, the survival benefit of UPTRAVI® cannot be confirmed from these data.[6]
PAH is a rare disease, with an estimated prevalence of 10–52 cases per million.[7] In certain at-risk groups, the prevalence can be substantially higher.[8][9]
Consistent with the primary endpoint outcomes of the overall population, UPTRAVI® reduced the risk of disease progression vs placebo in patients with CTD-PAH by 41% (HR 0.59; 95% CI: 0.41–0.85).[10]
The treatment effect with UPTRAVI® was consistent in patients with CTD-PAH across CTD subtypes, including systemic sclerosis (SSc)-associated and systemic lupus erythematosus (SLE)-associated PAH (see below). UPTRAVI® also reduced the risk of disease progression vs placebo by 32% in patients with mixed CTD-PAH/other CTD-PAH (HR 0.68; 95% CI: 0.31–1.47).[10]
UPTRAVI® reduced the risk of disease progression by 44% vs placebo in patients with SSc-PAH.[10]

UPTRAVI® reduced the risk of disease progression in patients with PAH and <3 CV comorbidities* by 34% vs placebo. In patients with PAH with ≥3 CV comorbidities, UPTRAVI® reduced the risk of disease progression by 50% vs placebo.[12]
Adapted from Rosenkranz et al. 2022[12]
The treatment effect of UPTRAVI® is not influenced by the number of comorbidities or the presence of a specific comorbidity (interaction p value=0.432).[12]
UPTRAVI® is contraindicated in patients with certain CV comorbidities. Please refer to the full Uptravi® PI. [5]
*CV comorbidities were defined as: BMI >30 kg/m2, history of essential hypertension, diabetes mellitus or historical evidence of significant coronary artery disease.[12]

§Haemodynamic parameter cut-offs required a PAWP/LVEDP of ≤12 mmHg when PVR was ≥3.75 to <6.25 WU. If PVR was ≥6.25 WU, the PAWP/LVEDP had to be ≤15 mmHg.[12]
UPTRAVI® reduced the risk of disease progression by 41%, 35% and 42% in the subgroup of patients with 0, 1 and 2 low-risk criteria, respectively, compared with placebo.*[4]

§p value for interaction.[4]
#HRs could not be calculated in patients with 3 low-risk criteria because of the low numbers of morbidity/mortality events that occurred.[4]
In the GRIPHON trial, the effect of UPTRAVI® was consistent with the primary endpoint for all background therapy subgroups. UPTRAVI® reduced the risk of disease progression vs placebo by 43% in patients not receiving background therapy at baseline, by 42% in patients receiving phosphodiesterase type 5 inhibitor (PDE-5i) monotherapy at baseline and by 34% in patients receiving endothelin receptor antagonist (ERA) monotherapy at baseline.[13]
UPTRAVI® also improved long-term outcomes for patients when added in triple combination therapy, including those in World Health Organization (WHO) functional class (FC) II and III (see below).[14]
Adding UPTRAVI® to double combination therapy reduced the risk of disease progression by 37% vs placebo in the overall population.[14]

Early* initiation of UPTRAVI® improved long-term outcomes vs placebo to a greater degree than when initiated later.* Treatment with UPTRAVI® reduced the risk of disease progression vs placebo when initiated within 6 months of diagnosis and when initiated after 6 months from diagnosis.[15]
Adapted from Gaine et al. 2021[15]
At baseline, 53.7% of patients who were diagnosed early were found to be in WHO FC I/II, while 42.7% of patients diagnosed later were in WHO FC I/II.[15]

The overall treatment goal in PAH is to achieve and maintain a low-risk status,[17] which has been shown to be prognostic for better long-term outcomes.[4][18][19] UPTRAVI® helps patients improve and maintain their risk status in both a clinical trial and the real world.[4][18][20]
In the GRIPHON trial, patients receiving UPTRAVI® were 69% more likely to improve their risk status from baseline to Week 26 compared with placebo.*‡[4]
