In patients treated in a real-life setting, adherence to therapy, SVR rates, predictive factors of SVR and safety results were close to those observed in randomized trials. A high SVR in G1 naive patients with no fibrosis warrants further study and might suggest earlier treatment.

Long-term therapy with peginterferon alpha-2a did not reduce liver fibrosis degree assessed by morphometry and blood tests as compared with alpha-tocopherol. Blood tests could be useful to assess liver fibrosis changes in clinical trials.

Objective : To update the health economic evaluation of pirfenidone in the treatment of idiopathic pulmonary fibrosis (IPF) compared to all available alternatives strategies (Best supportive care – BSC and nintedanib), based on a cost-utility model previously validated by the CEESP’s (French Committee for Economic Evaluation) in 2014. Methods : A standard Markov cohort model, adapted to French methodology guidelines, was used to simulate the therapeutic management and the course of IPF patients (including potential adverse events) using the collective perspective. Cost-effectiveness was evaluated regarding life years (LY); quality-adjusted life-years (QALY); average cumulative costs; the incremental cost-effectiveness ratio (ICER) expressed in cost per QALY gained. Data were retrieved from trials, meta-analysis, literature, health insurance and hospitalisation databases, and national tariffs. Results : Over 15 years, total costs accumulated in the pirfenidone strategy were estimated at €99,477 per patient, €104,610 in nintedanib, and €14,177 in Best Supportive Care (BSC). The total number of QALYs accumulated equalled 5.20 (6.91 LYs), 4.52 (5.98 LYs), and 3.79 (4.98 LYs), respectively. Pirfenidone was estimated to be dominant over nintedanib with incremental costs of -€5,133 and 0.67 more QALYs accumulated. Incremental cost versus BSC was €85,300 and 1,404 QALY gained. The cost-effectiveness ratio was estimated at 60,738€/QALY when compared to BSC. Conclusion : Pirfenidone is likely to be a cost–effective strategy compared to BSC and seems more efficient and less costly compared to nintedanib for the treatment of patients with IPF in France.

Patients and Methods Study design This study was initiated after a request of the French health authorities (HAS) in June 2004 to conduct a post registration study assessing long-term efficacy and safety of enfuvirtide in HIV-1infected patients in real-life settings. This multicenter, prospective, observational cohort study was performed in France. Patients were consecutively included in the study if they met the following criteria: HIV-1 infection, age at least
