London, UK, 14 December 2015
BTG plc (LSE: BTG), the specialist healthcare company, today announces the successful outcome of the RENEW study, the pivotal US randomised controlled clinical trial comparing the safety and efficacy of the PneumRx endobronchial coil implant (EBCI) with a medical therapy control group in patients with homogeneous and/or heterogeneous severe emphysema.
All primary and secondary endpoints of the study were met.
Patients treated with the PneumRx EBCI showed a statistically significant 10.2 metre benefit vs. control patients in change in the six minute walk test (6MWT) at 12 months, which was the study primary endpoint (p=0.0153).
Importantly, patients treated with the PneumRx EBCI exhibited statistically significant and clinically meaningful improvements vs. control patients at 12 months in Quality of Life measured by Saint George Respiratory Questionnaire (SGRQ) (mean improvement of 8.9 points over the control group, p < 0.0001) and lung function measured by Forced Expiratory Volume in one second (FEV1) (mean litres percent improvement of 8.8% over the control group, p < 0.0001).
Serious adverse events in the treatment and control groups were as expected in a patient population of mostly GOLD IV patients. Events associated with bronchoscopy and EBCI placement such as pneumothorax, lower respiratory tract infections, respiratory failure, haemoptysis, COPD exacerbation, and dyspnoea occurred, as anticipated, at a higher rate in the treatment arm.
Louise Makin, BTG’s CEO, commented: “We are delighted with the successful outcome of RENEW, showing significant benefit in patients treated with the PneumRx® Coils in one of the largest randomised controlled clinical trials of a medical device in patients with severe emphysema to date incorporating both patient reported and objective outcomes. We will now progress our regulatory application in the US, which we anticipate submitting around mid-2016.”
RENEW included 315 patients who were randomised to receive treatment with the PneumRx EBCI or standard of care medical therapy. The primary endpoint of the study was a mean absolute improvement from baseline at 12 months in the 6MWT. The secondary endpoints included a 6MWT responder analysis, FEV1mean percent change measured using spirometry and SGRQ mean absolute difference. Detailed analysis of the data continues, with full data expected to be submitted to a peer-reviewed journal for publication in due course.
The PneumRx Endobronchial Coil Implant (EBCI) is a shape-memory nitinol coil implanted in the sub-segmental airways of the lung in patients with severe emphysema via a minimally invasive bronchoscopic procedure.
