Pilot Trial Of Omeprazole in Idiopathic Pulmonary Fibrosis (IPF)

Status Completed

Clinical Trial Summary

Idiopathic pulmonary fibrosis (IPF) is a disease of unknown cause in which areas of normal lung tissue are replaced by scars. As a result it becomes harder for the lungs to extract oxygen from the air. IPF is commonly progressive, and around 50% of patients diagnosed with the disease die after approximately 3 years. The most common, troublesome symptoms of IPF are breathlessness on exertion, and cough. No drug treatments have been unequivocally shown to improve the death rate, or to significantly impact upon symptoms, in IPF.

In recent years it has been recognised that cough can be caused by small amounts of liquid coming up from the stomach and "going down the wrong way" into the lungs, a process commonly known as "reflux". As liquid in the stomach is usually acidic, patients' lungs may repeatedly be exposed to small amounts of acid. Reflux is unusually common in IPF and could potentially contribute to the debilitating cough found with the disease. However there are many potential causes for cough in IPF.

Stomach acid can be efficiently "switched off" by drugs called "proton pump inhibitors", one of which is called omeprazole. If reflux of stomach acid does contribute to cough in IPF, omeprazole might be expected to reduce cough. The purpose of this study is therefore to test whether omeprazole does reduce cough in patients with IPF. Sixty patients with IPF will be randomly allocated to have 3 months of omeprazole or a placebo. Neither the patient nor the doctor will be aware which treatment has been given, ie this is a randomised "double-blind", placebo--controlled trial. Patients' cough frequency will be measured before and after treatment and the change in cough frequency compared in those receiving omeprazole and those receiving placebo. Change in cough frequency is the main thing we aim to compare, but a range of other measurements will be assessed such as the numbers of patients eligible to take part, agreeing to randomisation and providing outcome data, patients' lung function, symptom scores, the amount of reflux, and the amount of inflammation in the lungs.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
