Next Phase Starts In the World's Largest Breath-Based Clinical Trial
News Sep 22, 2016
Owlstone Medical announced that it is expanding its Lung Cancer Indicator Detection (LuCID) clinical trial. The study, originally funded by the Small Business Research Initiative for Healthcare (SBRI Healthcare), an NHS England funded initiative, aims to save 10,000 lives and save the NHS £245 million by 2020 with a quick, easy to use, non-invasive, high-compliance breath test to detect lung cancer. The study will recruit up to 3,000 patients across 21 sites in the UK and Europe, making it the world’s largest breath-based study ever undertaken for early cancer detection.
If detected at stage 1, the 5-year survival rate for lung cancer is 54%, but this drops to just 4% if the cancer is detected at stage 4. Current lung cancer screening tests, such as low dose computed tomography (CT screening), have been shown to result in a high number of false-positives and therefore unnecessary, invasive follow-up procedures on healthy patients.
The mutations that drive the development of lung cancer have downstream effects on the metabolites we exhale, even in the very early stages of lung cancer. Owlstone Medical uses the Respiration Collector for In Vitro Analysis (ReCIVA), in combination with the Field Asymmetric Ion Mobility Spectrometer (FAIMS) sensor platform, to accurately and selectively detect lung cancer volatile organic compounds (VOCs) in breath.
The trial is moving to the next phase as a consequence of positive interim sensitivity and specificity data, when compared to other available tests, with over 97% of patients reporting the breath test to be comfortable to perform.
The study is being led by Dr Robert Rintoul, lead clinician for Thoracic Oncology and Director of the Clinical Trials Unit at Papworth Hospital, Cambridge, UK, and will recruit patients in order to validate breath biomarkers for the early detection of cancer and differentiation between benign and malignant tumors, which is a major problem in current screening approaches. The trial will compare Owlstone Medical’s platform with current CT and PET screening tests, with the aim of demonstrating its ability to reduce the number of false-positive results and complications seen from invasive biopsy follow-ups.
Patient recruitment is on target with twelve sites in the UK and elsewhere in Europe currently recruiting with nine more sites to come on board shortly.
Commenting on the study, Dr Robert Rintoul said: “The need to explore novel approaches for the early detection in lung cancer has never been greater. I am particularly excited about the opportunity that the Owlstone LuCID project brings to study the role of VOCs for the early detection of lung cancer. If VOCs work, then it may be possible to use a simple breath test to help identify whether someone has lung cancer or not.”
Billy Boyle, co-founder and CEO at Owlstone Medical, said: “Early detection through improved screening is the greatest opportunity for improving patient outcomes. Owlstone Medical was created specifically to advance our breathalyzer for very early stage diagnosis of disease, to enable more effective treatment and better patient outcomes.”
At the European Respiratory Society International Congress in London earlier this month, the academic steering committee for Owlstone’s LuCID clinical trial Phase II project met, and Owlstone held a workshop for its Stratification of Asthma Treatment by Breath Analysis (STRATA) SBRI Healthcare Phase I project, to combine input of a wide range of stakeholders into the project and report initial trial progress. This project aims to allow patients suffering from difficult-to-treat severe asthma to quickly find the treatment that will work best for them, increasing quality of life for patients and reducing health care costs.
Bubble formation is typically a much more random process than liquid droplet formation, yet the generation of uniform drops and bubbles is very desirable in microfluidics. Researchers have now shown that under certain conditions, bubbles can also be coaxed to form spheres as perfectly matched as droplets.READ MORE
