A study to identify whether it is safe, if it works, and how much and how often cysteamine should be given to adult patients with Cystic Fibrosis (CF) who are being treated for a worsening of CF associated lung disease.

A Randomized, Double-Blind, Parallel Group, Placebo-Controlled Study Investigating the Optimal Dose Regimen, Efficacy, and Safety of Adding Oral Cysteamine in Adult Patients with Cystic Fibrosis (CF) Being Treated for an Exacerbation of CF-associated Lung Disease.

Design outcomes

Primary

Measure	Time frame
Main Objective: - to determine the optimal dose and frequency of cysteamine in exacerbations of CF-associated lung disease - to determine the best questionnaire for evaluation of clinical benefit arising from use of cysteamine in exacerbations of CF-associated lung disease - to determine the effects of treatment with cysteamine on safety parameters;Secondary Objective: to determine the effects of treatment with cysteamine on an exacerbation of CF-associated lung disease for each of the following: - sputum IL8 and neutrophil elastase levels - forced expiratory volume in the first second (FEV1) - weight - C-reactive protein (CRP) - blood leukocyte count - assessment of blood and sputum cysteamine levels;Primary end point(s): - Change from baseline in patient health-related questionnaires (CFRSD-CRISS, Jarad and Sequeiros Smptom Score Questionnaire - Change from baseline in sputum bacterial load of (a) total CFU per ml and per mg and (b) gram negative CFU per ml and per mg at Day 7, Day 14 and Day 21 following a CF exacerbation - Change from baseline in sputum IL8 and neutrophil elastase levels at Day 7, Day 14 and Day 21 following a CF exacerbation - Change from baseline to Day 7, Day 14 and Day 21 in FEV1, weight, CRP, blood leucocyte count and CFQ-R - Assessment of blood and sputum cysteamine levels at Day 14 - Patient Global Assessment of Exacerbation outcome;Timepoint(s) of evaluation of this end point: See section E.5.1.
