(ARTEMIS-IPF) Randomized, Placebo-Controlled Study to Evaluate Safety and Effectiveness of Ambrisentan in IPF
Summary
The ARTEMIS-IPF study was conducted to determine if ambrisentan was effective in delaying disease progression and death in participants with idiopathic pulmonary fibrosis (IPF), to evaluate its safety, and to evaluate its effect on development of pulmonary hypertension, quality of life, and dyspnea (shortness of breath) symptoms in this participant population. Participants were randomized in a 2:1 ratio to receive ambrisentan or placebo, respectively. Participation in the study was to be up to 4 years, depending on how long it would take to enroll participants and observe study events. After randomization, visits to the clinic took place every 3 months, and laboratory procedures were performed every month.

Outcome
Missed primary endpoint
Stopped: “Lack of efficacy”
paper Ambrisentan-treated patients were more likely to meet the prespecified criteria for disease progression (90 [27.4%] vs. 28 [17.2%] patients; P = 0.010; hazard ratio, 1.74 [95% CI, 1.14 to 2.66]). PMID 23648946 ↗
paper Ambrisentan was not effective in treating IPF and may be associated with an increased risk for disease progression and respiratory hospitalizations. PMID 23648946 ↗
