John Winn’s office at Microsoft Research looks like that of any typical academic: on one wall is a whiteboard graffitied with impenetrable equations and mathematical scribblings, on the opposite wall books and files line shelves, and on his desk are photos of his family.

His desk, however, is somewhat different: it can rise or fall, depending on whether he wants to work standing or sitting – and underneath is a treadmill for walking and working at the same time. “There have been times when I’ve been deep in thought and almost fallen off it,” he jokes.

Winn has cystic fibrosis (CF) and keeping fit is an important part of managing his condition: the stronger his lung function, the better equipped he is to fight the potentially life-threatening infections that plague people living with the condition.

CF occurs when an individual inherits two copies of a single genetic variant, one from each parent. ̽��ֱ��disease causes a build-up of thick, sticky mucous in the lungs, intestines and organs, and those affected by the condition are particularly susceptible to lung infections leading to progressive inflammatory lung damage. Although life expectancy for people with CF has almost doubled in recent decades, it is still significantly below average.

Winn is a machine learning specialist and is using his expertise to fight the condition that affects his everyday life. Together with Professor Andres Floto from the Department of Medicine at Cambridge, he is turning data from the daily lives of people with cystic fibrosis into potentially life-saving information.

As part of this study, funded by the Cystic Fibrosis Trust and Royal Papworth Hospital, participants have been submitting data – everything from heart rate and lung function through to self-reported wellbeing – via an app that also monitors their activity levels. Machine learning then sifts through the data, looking for patterns and – it’s hoped – building a model that can predict when a patient’s health is about to deteriorate and advise them to seek medical help.

“ ̽��ֱ��overarching principle is about giving people control over their own health data and making it work for them,” says Winn. “There’s some informal feedback that just participating in the study and taking these readings has already improved health outcomes for some individuals: for example, it’s helped with adherence with taking their medications as they noticed that if they missed taking certain medicines, their readings got worse.”

̽��ֱ��project is just one strand of a major new Cystic Fibrosis Innovation Hub based on the Cambridge Biomedical Campus and run by Floto. ̽��ֱ��Hub is supported through a £5 million commitment from the Cystic Fibrosis Trust and matching funds from the ̽��ֱ�� of Cambridge. It will strengthen existing collaborations across the ̽��ֱ�� and with the Wellcome Trust Sanger Institute, as well as build new collaborative research networks with CF centres around the UK. ̽��ֱ��Trust’s Chief Executive, David Ramsden, said it will “provide��in CF research across the country”.

Floto agrees with this sentiment: “We have an opportunity to uplift UK CF research in general by providing knowhow, training and reagents in a number of areas including genomics, bioinformatics, stem cells and clinical trials technology.”

A major part of the Hub’s activities will be around developing new drugs that target chronic inflammation in CF, in collaboration with the pharmaceutical company GSK as part of the GSK/Cambridge Strategic Partnership, as well as new antibiotic therapy for the main causes of lung infection in the condition.

Finding new drugs against these bacteria is becoming increasingly urgent – Floto and Professor Julian Parkhill at Sanger recently showed that Mycobacterium abscessus, the pathogen behind one of the most serious infections, is becoming increasingly multi-drug resistant and spreading globally. This is one reason why people with CF are advised not to meet each other.

“Clearly the techniques that we develop – and the drug-like molecules that come out of it – will have more general applicability to patients with other multi-drug resistant infections,” Floto says. This will be welcome news to England’s Chief Medical Officer, Professor Dame Sally Davies, who has warned of a future where “any one of us could go into hospital in 20 years for minor surgery and die because of an ordinary infection that can’t be treated by antibiotics.”

̽��ֱ��timing of all this is particularly good: Papworth Hospital, whose Adult Cystic Fibrosis Centre has gained a national and international reputation for its treatment of patients and its contribution to research, is due to move to the Biomedical Campus later in 2018. ̽��ֱ��CF wards will feature state-of-the-art air flow systems, designed with Floto’s work on the spread of multi-drug resistant CF pathogens in mind.

This close proximity between the patients and the researchers will help Floto test the new treatments he is pioneering. He is particularly excited about the potential for new cellular therapies he’s developing with Professor Ludovic Vallier at the Department of Surgery. Floto describes these as their “moon shot”. These would involve taking cells from a CF patient, re-programming them – correcting the genetic defect along the way – and then re-injecting them into patients. “This could provide a way to regenerate damaged lungs,” he says.

Floto knows his plans for the Hub are ambitious, but given that it’s almost 30 years since the gene that causes CF was discovered and there is still no cure for the disease, believes it’s time to take this shot at the moon.

Floto’s collaborators in the CF Innovation Hub include Chris Abell (Chemistry), Sir Tom Blundell (Biochemistry), Julian Parkhill and Ludovic Vallier.
