A Pilot Trial of Herpesvirus Treatment in Idiopathic Pulmonary Fibrosis (IPF)

Study Purpose

The investigators will conduct a single-center, prospective, randomized, placebo-controlled, double-blind pilot study of anti-herpesvirus therapy in patients with idiopathic pulmonary fibrosis (IPF). Patients with mild, moderate or severe IPF with serologic evidence of current or past Epstein-Barr Virus (EBV) or cytomegalovirus (CMV) infection. Randomization will be to pirfenidone plus placebo or pirfenidone plus valganciclovir. Thirty subjects will be enrolled and randomized to treatment with pirfenidone plus valganciclovir (20 subjects) or pirfenidone plus placebo (10 subjects) for 12 weeks. The primary outcome will be safety and tolerability will be determined by type, frequency and duration of adverse events (AEs) and serious adverse events (SAEs) after 12 weeks of study drug treatment. All study subjects will be offered bronchoscopy with bronchoalveolar lavage (BAL) at study initiation and upon completion of treatment (12 weeks). Subjects will then be followed up at routine clinic visits at 6, 9 and 12 months for data collection.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
