prevalence of IPF was estimated to range from 4.0 per 100,000 persons aged 18 to 34 yr to 227.2 per 100,000 among those aged 75 yr or older

The pirfenidone lessons
• A drug that works in the bleomycin model
can work in humans
• A trial of a drug can be positive in IPF
• A drug without a definitive molecular target
may work
• An IPF drug is approved by EMEA and
consequently by AIFA and FDA (october 2014)

• slows the progression in patients with early disease
• even if there is progression in terms of FVC% (>10%)
mantains its efficacy both in terms of function and
survival during the following 6 months
Esbriet appears beneficial accross of IPF patients enrolled in different trials

Pirfenidone and moderate severe disease: An Italian real life study
In our national experience,
pirfenidone reduces the
rate of annual FVC decline
and provides significant
treatment benefit for
patients with moderate-
severe disease, suggesting
that the drug may also be
effective in patients with
more advanced disease

The primary end point was the annual rate of decline in forced vital capacity (FVC) Key secondary end points were over a 52-week period•the time to the first acute exacerbation• the change from baseline in the total score on the St. George’s Respiratory Questionnaire

Main Results of INPULSIS-1 and INPULSIS-2
a) Nintedanib reduces the decline in FVC, which is
consistent with a slowing of disease progression;
b) Difference between the nintedanib and placebo
groups in the time to the first acute exacerbation
and quality of life (SGRQ) are not clear due to
the result differences between the 2 trials
c) Nintedanib is frequently associated with diarrhea,
which led to discontinuation of the study
medication in less than 5% of patients

• the FVC% baseline value, the presence of emphysema, the degreeof honeycombing at HTCT do not affect the rate of diseaseprogression of the size of nintedanib effect
• the FVC% values do affect the rate of acute exacerbations
Nintedanib 150 mg bid on slowing disease progression wasmainained up to 76 weeks
