Pharmacotherapy for idiopathic pulmonary fibrosis: current landscape and future potential
European Respiratory Review, 2017
Over the past two and a half decades, many clinical trials have been designed to determine the safety and efficacy of pharmacotherapy for patients with idiopathic pulmonary fibrosis (IPF). However, so far, only two drugs (pirfenidone and nintedanib) have been found to have an impact on disease progression as defined by reducing the rate of decline in forced vital capacity over a year among IPF patients with mild to moderate impairment in lung function. These two drugs have been approved for treatment of IPF by regulatory agencies and are currently in clinical use worldwide. This article summarises the current landscape of pharmacotherapy for IPF and highlights the prospects and potential of new therapies that are currently being pursued in clinical trials.
Pharmacological treatment of idiopathic pulmonary fibrosis: from the past to the future
European Respiratory Review, 2013
During the past decade important progress has been made regarding the pathogenesis of idiopathic pulmonary fibrosis (IPF), which is the most devastating form of idiopathic interstitial pneumonia with a median survival of 3 years. The knowledge gained has been used to design multicentre, randomised, placebo-controlled trials in order to investigate agents with different mechanisms of action. Encouraging results have led to licensing of the first IPF-specific drug, pirfenidone. However, the road to successful treatment is still long. The main aim for the future should be the careful design of clinical trials, by choosing the most clinically meaningful end-point and keeping in mind that combination of various agents may be more effective. This approach has been used in the treatment of lung cancer with which IPF presents many similarities.
Pharmacological management of Idiopathic Pulmonary Fibrosis: current and emerging options
Expert Opinion on Pharmacotherapy, 2020
Introduction: Idiopathic Pulmonary Fibrosis is a chronic, progressive lung disease characterized by worsening lung scarring and the radiological/histological pattern of usual interstitial pneumonia. Substantial progress has been made in the clinical management of IPF in the last decade. The two novel antifibrotics, Nintedanib and Pirfenidone have changed the landscape of IPF, by hindering disease progression; however, the drugs have significant discontinuation rates, due to adverse events and do not offer a definitive cure, as such IPF remains a deleterious disease with poor survival. Areas covered: In this review, the authors focus on the current and emerging pharmacological options in the treatment of IPF. They include a summary of the current approach including treatment of comorbidities and then discuss promising drugs in the drug pipeline. Expert opinion: IPF remains a disease with detrimental outcomes. The plethora of emerging pharmacological treatments brings hope for the future. The current pharmacological 'one fits all' approach has been proven effective in slowing disease progression. The future lies in an oncological approach with combination of therapies. We expect to see a change in clinical trial endpoints and a more inclusive approach for the diagnosis of IPF.
Core Evidence, 2016
The landscape of idiopathic pulmonary fibrosis (IPF) has changed. The significant progress regarding our knowledge on the pathogenesis of the disease together with the experience achieved after a series of negative trials has led to the development of two drugs for the treatment of IPF. Both pirfenidone and nintedanib can slow significantly the rate of disease progression. They are safe with side effects that can be either prevented by close collaboration between health care professionals and patients or treated successfully when they occur, rarely leading to treatment discontinuation. However, there are still few unanswered questions regarding the application of the beneficial results of pharmaceutical trials in the general population of IPF patients. Long-term "real-life" studies are being undertaken to answer these questions. In this article, we focus on the advances that have led to the development of the antifibrotic agents with particular focus on pirfenidone.

Idiopathic Pulmonary Fibrosis (IPF) is a chronic fibrotic disease characterized by a progressive decline in lung function with a median survival of 3-5 years after diagnosis. The course of disease is highly variable and unpredictable, often punctuated by episodes of acute respiratory failure, known as acute exacerbations. The incidence of IPF is on the rise due to the aging population, as age is the most important risk factor for this disease. Pirfenidone and nintedanib are the two anti-fibrotic drugs approved for IPF which have shown reduction in lung function decline. This review will discuss the efficacy, safety and tolerability profile of pirfenidone from clinical trials and the real-world clinical experience. Pirfenidone reduces the decline in lung function and improves progression-free survival in patients with IPF. It is generally well tolerated with the most common side effects being gastrointestinal and phototoxicity.
Treatment of Idiopathic Pulmonary Fibrosis with a New Antifibrotic Agent, Pirfenidone
American Journal of Respiratory and Critical Care Medicine, 1999
Idiopathic pulmonary fibrosis (IPF) is a progressive clinical syndrome of unknown etiology and fatal outcome. Currently available therapies are ineffective and associated with significant adverse effects. Pirfenidone, a new, investigational antifibrotic agent, was evaluated for its tolerability and usefulness in terminally ill patients with advanced IPF. Consecutive patients with IPF and deterioration despite conventional therapy or who were unable to tolerate or unwilling to try conventional therapy were treated with oral pirfenidone. Treatment was administered on a compassionate basis (open-label). Fifty-four patients were followed for mortality, change in lung function, and adverse effects. Their mean age was 62, mean duration of symptoms 4.6 yr, and time since lung biopsy was 3.2 yr. Conventional therapy was discontinued in 38 of 46 patients; the other eight were able to decrease their prednisone dosage and eight had no previous conventional treatment. One-and 2-yr survival was 78% (95% CI 66%, 89%) and 63% (95% CI 50%, 76%), respectively. Patients whose lung functions had deteriorated prior to enrollment appeared to stabilize after beginning treatment. Adverse effects were relatively minor. The results of this study are encouraging. Pirfenidone is a promising new treatment for IPF that is well tolerated. Raghu G, Johnson WC, Lockhart D, Mageto Y.

Targeted Therapy for Idiopathic Pulmonary Fibrosis: Where To Now?
Drugs, 2016
Idiopathic pulmonary fibrosis (IPF) is an aging-associated, recalcitrant lung disease with historically limited therapeutic options. The recent approval of two drugs, pirfenidone and nintedanib, by the US Food and Drug Administration in 2014 has heralded a new era in its management. Both drugs have demonstrated efficacy in phase III clinical trials by retarding the rate of progression of IPF; neither drug appears to be able to completely arrest disease progression. Advances in the understanding of IPF pathobiology have led to an unprecedented expansion in the number of potential therapeutic targets. Drugs targeting several of these are under investigation in various stages of clinical development. Here, we provide a brief overview of the drugs that are currently approved and others in phase II clinical trials. Future therapeutic opportunities that target novel pathways, including some that are associated with the biology of aging, are examined. A multi-targeted approach, potentially...
Pirfenidone: significant treatment effects in idiopathic pulmonary fibrosis
The clinical respiratory journal, 2012
Pirfenidone has been shown in three recently published trials to slow down the progression of the devastating interstitial lung disease, idiopathic pulmonary fibrosis (IPF). The precise mechanisms that initiate and perpetuate the histopathological process leading to lung fibrosis in IPF are still uncertain, but increased concentrations of reactive oxidative species and fibrogenetic factors have been observed in the pulmonary tissue of patients. Although the exact mechanisms of its action are unknown, pirfenidone is a small molecule with antifibrotic and some hydroxyl scavenger properties that has recently been approved in Europe and elsewhere for the treatment of IPF. Along with the new ATS/ERS/JRS/ALAT 2011 statement for 'Evidence Based Guidelines for Diagnosis and Management', there is now a more profound basis for offering IPF patients an evidence-based evaluation and treatment. This review summarizes the background to the recommended use of pirfenidone for the treatment ...

Idiopathic pulmonary fibrosis (IPF) is a progressive and fatal lung disease that up to now has been associated with a poor prognosis. However, the results of the INPULSIS and ASCEND trials and the approval of nintedanib and pirfenidone have marked the beginning of a new era for IPF patients. Questions remain, however. Should these drugs be used earlier? What effect will they have on more severe disease? Will their effects last beyond the trial period? This manuscript is the outcome of a multidisciplinary meeting between pulmonology, radiology, and pathology clinicians on the use of antifibrotic agents in IPF. In our opinion, the existing data show that pirfenidone and nintedanib slow functional decline in early stages of disease. These drugs also appear to result in therapeutic benefits when administered to patients with advanced disease at diagnosis and maintain effective over time. The data also suggest that continuing antifibrotic therapy after disease progression may confer bene...
Clinical trials in idiopathic pulmonary fibrosis: where we have been and where we are going
Current Respiratory Care Reports, 2012
Idiopathic pulmonary fibrosis (IPF) is the most common and most lethal diffuse fibrosing lung disease, with an increasing incidence and a mortality rate that exceeds that of many types of cancer. At present, there is no effective standard treatment recommended by guideline documents. As such, the unmet medical need is high. Recently, several high-quality clinical trials, evaluating safety and efficacy of different novel molecules, have been concluded. The results have mostly been disappointing, although some compounds have shown promising results. In particular, pirfenidone seems to be the most advanced molecule for IPF treatment, having been approved in Europe, Japan and India. Nintedanib, a triple kinase inhibitor, has almost completed enrolment of Phase III trials, based on promising Phase II results. Randomized controlled trials still represent a valid choice for IPF patients, and their completion is critically important to achieving the ultimate goal of curing IPF. Future approaches will probably include the evaluation of currently available agents alone and in combination, the identification of novel drugs with pleiotropic actions, and trials with validated, weighted composite endpoints.
