#ATS2018 – Esbriet Lowers Risk of Seasonal IPF Flares Leading to Hospitalizations, Phase 3 Data Show

Seasonal flares of disease activity that can lead to idiopathic pulmonary fibrosis (IPF) patients being hospitalized, especially in the winter months, appear to be effectively countered by treatment with Esbriet (pirfenidone) compared to placebo, a new retrospective analysis of data from Phase 3 clinical trials shows.

Results were presented by Brett Ley, MD, a pulmonologist at University of California San Francisco, in the poster, “The Effect of Season on Hospitalization and Mortality in Patients with Idiopathic Pulmonary Fibrosis Treated with Pirfenidone Versus Placebo” at the 2018 American Thoracic Society (ATS) International Conference held May 18-23 in San Diego, California.

Seasonal patterns of disease activity are common in chronic lung diseases, with winter months typically being a period of peak activity in IPF and other pulmonary fibrosis patients.

In their study, researchers analyzed data from Phase 3 trials testing Esbriet (marketed by Genentech) against placebo in IPF patients — the ASCEND (NCT01366209) and CAPACITY (NCT00287729 and NCT00287716) studies — to determine if the season influenced hospitalization and mortality rates in this patient population.

Specifically, they looked at seasonal effects on respiratory-related and non-respiratory-related hospitalizations, and deaths linked to respiratory problems, across 12 months.

The opening of each season was set in the study as March 22 (spring), June 22 (summer), Sept. 22 (fall), and Dec. 22 (winter).  Within each season, researchers compared clinical outcomes between placebo and 623 Esbriet-treated IPF patients and 624 given placebo.

Analysis showed that placebo-treated patients had a significant trend for a seasonal effect in respiratory-related hospitalizations or deaths — while no significant trend was observed among Esbriet-treated patients.

During winter months, in particular, placebo-treated patients had a 52% higher rate of respiratory hospitalizations compared to those given Esbriet.

Season changes did not at influence the rate of non-respiratory hospitalizations in either group, placebo or Esbriet, the study reported.

“In patients with IPF who received placebo in the ASCEND and CAPACITY studies, more respiratory hospitalizations and respiratory-related hospitalizations or deaths from any cause were observed in Fall and Winter than in Spring and Summer,” the researches concluded. “Pirfenidone [Esbriet] appears to blunt seasonal peaks in respiratory hospitalizations.”

    does anyone know if there are benefits of taking the Esbriet 801 pill three times a day versus taking the esbiet 267 pill nine times a day???

      Hey David,

      I just started my Esbriet 801 pills 3 times a day for 5 days now. I can tell you that I like them much better than the nine 267 capsules a day. The sight of the white plastic like capsules almost made me sick just looking at them. I took them for 8 mos. and did not like them at all . The tablets go down easier, are less hard on my stomach (enteric coated) and give me less gas. My provider said that no one who has gone on the tablets had requested to go back to the capsules.

      My husband was having a difficult time taking the three pills a day, three times a day. It was getting so bad that he dreaded taking them and had to force them down. He switched to 3 pills a day and it has been a blessing.

    My specialist has described me as one of the unlucky ones.
    I am a keen golfer playing twice a week. After 5 weeks on Esbriet playing my regular game covered from head to toe my back turned bright red with small pimples.After 3 days my whole body turned red.
    My specialist explained this was a reaction from the Esbriet and the sunlight, not that I was sunburnt. Then the peeling starts, and continues. My specialist has suggested we try FELV.

    Hello Graham – I am sorry to hear of your reaction to the sun while taking Esbriet. What is FELV?
