Efficacy of pirfenidone in patients with idiopathic pulmonary fibrosis with more preserved lung function.

This post hoc analysis examined the differences in idiopathic pulmonary fibrosis disease progression and the effects of pirfenidone in patients stratified by more preserved versus less preserved baseline lung function status using forced vital capacity (FVC) or GAP (gender, age and physiology) index stage.Efficacy outcomes, i.e.

Effect of continued treatment with pirfenidone following clinically meaningful declines in forced vital capacity: analysis of data from three phase 3 trials in patients with idiopathic pulmonary fibrosis.

Background: The assessment of treatment response in idiopathic pulmonary fibrosis (IPF) is complicated by the variable clinical course. We examined the variability in the rate of disease progression and evaluated the effect of continued treatment with pirfenidone in patients who experienced meaningful progression during treatment.

Methods: The source population included patients enrolled in the ASCEND and CAPACITY trials (N=1247).

Safety of pirfenidone in patients with idiopathic pulmonary fibrosis: integrated analysis of cumulative data from 5 clinical trials.

Background: Pirfenidone is an oral antifibrotic agent that has been shown to reduce the decline in lung function in patients with idiopathic pulmonary fibrosis (IPF). We performed an integrated analysis of safety data from five clinical trials evaluating pirfenidone in patients with IPF.

Methods: All patients treated with pirfenidone in the three multinational Phase 3 studies (CAPACITY (studies 004 and 006), ASCEND (study 016)) and two ongoing open-label studies (study 002 and study 012 (RECAP)) were included in the analysis.

Pirfenidone for idiopathic pulmonary fibrosis: analysis of pooled data from three multinational phase 3 trials.

Pirfenidone is an antifibrotic agent that has been evaluated in three multinational phase 3 trials in patients with idiopathic pulmonary fibrosis (IPF). We analysed pooled data from the multinational trials to obtain the most precise estimates of the magnitude of treatment effect on measures of disease progression.All patients randomised to pirfenidone 2403 mg·day(-1) or placebo in the CAPACITY or ASCEND studies were included in the analysis.

Sensitivity Analyses of the Change in FVC in a Phase 3 Trial of Pirfenidone for Idiopathic Pulmonary Fibrosis.

Background: FVC outcomes in clinical trials on idiopathic pulmonary fibrosis (IPF) can be substantially influenced by the analytic methodology and the handling of missing data. We conducted a series of sensitivity analyses to assess the robustness of the statistical finding and the stability of the estimate of the magnitude of treatment effect on the primary end point of FVC change in a phase 3 trial evaluating pirfenidone in adults with IPF.

Methods: Source data included all 555 study participants randomized to treatment with pirfenidone or placebo in the Assessment of Pirfenidone to Confirm Efficacy and Safety in Idiopathic Pulmonary Fibrosis (ASCEND) study.

A phase 3 trial of pirfenidone in patients with idiopathic pulmonary fibrosis.

Background: In two of three phase 3 trials, pirfenidone, an oral antifibrotic therapy, reduced disease progression, as measured by the decline in forced vital capacity (FVC) or vital capacity, in patients with idiopathic pulmonary fibrosis; in the third trial, this end point was not achieved. We sought to confirm the beneficial effect of pirfenidone on disease progression in such patients.

Methods: In this phase 3 study, we randomly assigned 555 patients with idiopathic pulmonary fibrosis to receive either oral pirfenidone (2403 mg per day) or placebo for 52 weeks.

Hepatitis B virus and human immunodeficiency virus drugs in pregnancy: findings from the Antiretroviral Pregnancy Registry.

Background & Aims: Fetal safety of antiviral therapies is important given the long-term treatment of women with chronic hepatitis B (CHB) infection who may become pregnant. We analyzed neonatal safety data from the Antiretroviral Pregnancy Registry (APR), the largest safety database in pregnancy for antivirals used for HIV and CHB.

Methods: Data were extracted from APR cases prospectively enrolled between 1989 and 2011.

Histologic evidence of active liver injury in chronic hepatitis B patients with normal range or minimally elevated alanine aminotransferase levels.

Goals: To evaluate the proportion of patients with histologic evidence of active liver disease (HEALD) who have chronic hepatitis B (CHB) and normal/minimally elevated serum alanine aminotransferase (ALT). Sub-analysis was performed to determine whether HEALD based upon liver biopsy better correlates with ALT using modified ALT (30 men/19 women) upper limit of normal (ULN) criteria compared with local conventional laboratory.

Background: There are limited data on CHB with normal range ALT (NRALT).

Prospective, randomized, multicenter, controlled trial of a bioartificial liver in treating acute liver failure.

Objective: The HepatAssist liver support system is an extracorporeal porcine hepatocyte-based bioartificial liver (BAL). The safety and efficacy of the BAL were evaluated in a prospective, randomized, controlled, multicenter trial in patients with severe acute liver failure.

Summary Background Data: In experimental animals with acute liver failure, we demonstrated beneficial effects of the BAL.
