Idiopathic pulmonary fibrosis (IPF) belongs to a group of conditions called interstitial lung diseases (also known as ILD), which describes lung diseases that involve inflammation or scarring in the lung. IPF is a chronic progressive lung disorder associated with excessive tissue remodeling, scarring, and fibrosis, which makes the lungs unable to effectively transport oxygen into the bloodstream resulting in decreased lung function and increased nasal inflammation with increased mucus and coughing and poor quality of life. IPF usually affects people between the ages of 30 and 70. The most common signs and symptoms of IPF are shortness of breath and persistent dry, hacking cough. Many affected individuals also experience a loss of appetite and gradual weight loss. Most affected individuals survive 3 to 5 years after their diagnosis. However, the course of the disease is highly variable; some affected people become seriously ill within a few months, while others may live with the disease for a decade or longer. In most cases, IPF is sporadic and results from environmental damage to the lungs and not genetic factors. However, a small percentage of people have genetic risk factors resulting in familial pulmonary fibrosis. Sodium pyruvate is a natural antioxidant of the human body and as an antioxidant it has been shown to significantly reduce inflammatory agents throughout the human body, including the lungs and nasal passages, allowing nasal nitric oxide to reach the lungs to increase bronchodilation. In addition to 8 human clinical studies conducted on the effect of inhaled sodium pyruvate on the lungs, 7 human nasal inhalation clinical studies were conducted using a sodium pyruvate nasal spray which showed decreased nasal inflammation, a reduction in inflammatory cytokines, and when measured, demonstrated an increase in lung functions, a decrease in coughing, including in patients with pulmonary fibrosis and IPF. Cellular Sciences received Orphan Drug designations for Cystic Fibrosis and Interstitial lung Disease. A previous open label phase 2, 21-day, sub-chronic clinical trial was conducted that included 15 patients with pulmonary fibrosis (9 with pulmonary fibrosis and chronic obstructive pulmonary disease (COPD) and 6 with idiopathic pulmonary fibrosis without COPD) that remained on their normal medications but were also administered a 20 mM (2.2 mg/mL) sodium pyruvate nasal spray 3 times per day for 22 days. The data from this study showed that coughing episodes per 24 hours, and especially at night, were significantly reduced in all 15 patients on day 8 by 30% (p = 0.007) and continued to decrease on day 14 by 55% (p = 0.0001) and on the 22 day of the trial, coughing decreased by 59% (p = 0.0001). This correlated with a significant (p = 0.010) improvement in nasal irritation/erythema with most patients being free of irritation by day 22 (p < 0.001); and a significant (p = 0.010) increase in the group average expelled NO by day 8. A significant (p = 0.010) improvement in lung function (breathing) was observed in all patients with IPF without COPD (n=6) by day 1, increasing to p = 0.0005 by day 22 compared to their baseline therapies, determined by changes in FVC, FEV1, PEF, and FEV1/FVC ratios. The improved FEV1/FVC ratio from 52% to 86% was clinically significant and indicated that current therapies in use are inadequate to treat patient with IPF. The current study will expand on these findings by conducting a phase 3, double-blind placebo-controlled clinical trial to determine the effectiveness of 20mM sodium pyruvate nasal spray to decrease coughing in idiopathic pulmonary fibrosis patients. Individuals with a clinical diagnosis of idiopathic pulmonary fibrosis (as defined by the WHO and the Thoracic Society) will be solicited for participation in this phase 3 trial. Patients will have their degree of nasal inflammation and erythema, nasal cellular morphology, SaO2, and FEV1, FVC levels and blood workup recorded (baseline). Women of child-bearing age will provide a urine sample. The subjects will fill out a quality-of-life questionnaire (chronic respiratory disease questionnaire (CRDQ), and they will be given a data logbook in which they will record the number of coughs they experience each 24 hour period, for 7 days. The coughing data will be entered into the patients' logbooks and will be separated into "total coughs per 24 hours," and "night-time coughs." These data will be used to establish a baseline for coughing. After 7 days, patients will return to the clinic to begin the 21 day study where they will be given drug or placebo in a double-blinded fashion and will record their coughs daily in a logbook. Patients will return to the clinic on days 8, 15 and 22 for further evaluation.
