NCT02261727
The aim of this multi-centre, double blind, randomised, controlled trial (DBRCT) is to assess the effect of low dose theophylline, singly and in combination with low dose oral prednisone, on COPD (Chronic Obstructive Pulmonary Disease) exacerbations, quality of life and secondary clinical outcomes compared with usual therapy and placebo over 48 weeks of treatment. 1670 symptomatic patients with COPD will be recruited in China for comparison of low dose theophylline versus placebo and low dose theophylline + low dose prednisone The primary end-point for this study is the annualised COPD exacerbation rate between the treatment groups. Secondary outcomes included time to first severe exacerbation requiring hospitalisation or death, health status, and pre- and post-bronchodilator spirometry.

Non invasive ventilation is the standard of care in managing patients with exacerbation of chronic obstructive pulmonary disease. However no optimal mode of NIV delivery is established; failure rates remain high, attributed to asynchrony and leak associated with NIV. Neurally adjust ventilator assist is a new mode that may improve patient ventilator interactions, improve synchrony and contribute to improved outcomes. Likewise ASV is a mode principled on the closed loop system and is associated with reduction of work associated with breathing and improved outcomes. In this randomised, non-blinded trial, we study these two modes of NIV delivery in patients of AECOPD with hypothesis being that better synchrony with NAVA may translate to better clinical outcomes.
