The CF Geelong Genetics Therapy Innovation Grant 2023 (funded by CF Geelong)

Project Title: Harnessing the power of magnets: Improved effectiveness of airway gene therapy for the treatment of cystic fibrosis lung disease.

Principle Investigator: Alexandra McCarron

Institution: Adelaide

Value: $80,000

Duration: 1 year

Summary: Lung disease is the biggest contributor to reduced quality of life and premature death in people with cystic fibrosis (CF). Lung health progressively declines due to difficult-to-treat infections, resulting in gradual loss of lung function, trouble breathing, and irreversible tissue damage. New CFTR modulator drugs are beneficial for treating lung disease, however, there are thousands of individuals with CF that are either not eligible for these therapies, or do not tolerate them. Moreover, long-term follow-up of those taking modulator drugs shows that lung health typically continues to decline, demonstrating that these drugs are not curative.  

Airway gene therapy is a developing therapeutic method with clear potential to halt lung disease progression, or even provide a cure if given early in life. Delivering healthy copies of the CF gene to the airway cells could restore normal lung functioning and preserve lung health. Lung-directed gene therapy is already showing promise in pre-clinical testing. However, the most significant barrier to successful clinical translation is ineffective therapy delivery. Our proposal will harness the power of magnets as a novel tool to guide and hold our gene therapy product in the lungs, as a way to increase gene uptake into the target airway cells.

Abbie Fennessy Memorial Fellowship 2023 (funded by Mediplast)

Project Title: Remote symptom monitoring and automated treatment plans in children with Cystic Fibrosis

Principle Investigator: Jen Corda

Institution: Royal Children’s Hospital, Melbourne

Value: $5,000

Duration: 1 year

Summary:  In people with Cystic Fibrosis (CF) those who have higher numbers of lung (pulmonary) exacerbations (increased cough, sputum, shortness of breath) live shorter lives than those who have fewer exacerbations. We think that a delay in managing lung exacerbations can lead to worse results. In the past two years more people with CF have been interested in digital ways of getting CF healthcare. The COVID-19 pandemic meant more people got healthcare at home or in the local community rather than in hospitals. People with CF have said they want this to continue post pandemic.

This research study will look at new ways of providing care for people with CF using an online system, which is connected to our hospital medical record, that can pick up lung exacerbations in people with CF by examining symptoms (cough, sputum, breathing) that they enter into the system. If the system identifies a lung exacerbation, it will send out an action plan to the person with CF, explaining what they can do to help them get better from their lung exacerbation. The research study will run for 12 months and will compare the online detection system to normal CF care to understand if the new system is easy to use, liked and supported for ongoing use by people with CF and the CF team compared to the current system.

Conquer Cystic Fibrosis Lung Health Grant 2023 (funded by Conquer Cystic Fibrosis)

Project Title: Understanding and counteracting antibody-mediated inflammation driving lung damage

Principle Investigator: Timothy Wells

Institution: Frazer Institute, University of Queensland

Value: $49,812.82

Duration: 1 year

Summary:  Treatment of Pseudomonas aeruginosa infections in patients with Cystic Fibrosis (CF) and post-lung transplant remains a continuous clinical challenge. Despite the advent of modulators, in patients with existing lung damage, chronic P. aeruginosa infection remains a large problem. Novel methods to treat P. aeruginosa are desperately required. We recently discovered ‘cloaking antibodies’ in patients with chronic lung infection that paradoxically project the bacteria from immune killing. These antibodies are associated with worse lung function and outcomes in patients with CF and post lung-transplant. Excitingly, we have used plasmapheresis as a novel treatment to remove cAb, restore normal immune killing and ameliorate infection.  This treatment was highly successful in three patients with multi-drug resistant P. aeruginosa lung infections.

Despite this success, plasmapheresis is a broad and laborious treatment and refinements need to be made before large scale trials. Additionally, lung damage in these patients is driven by inflammation, and the link between cloaking antibodies and inflammation is not yet understood. Here we will investigate the mechanisms linking cloaking antibodies to inflammation. This data will reveal how cloaking antibodies lead to worse outcomes and identify new targets to improve the current treatment.

CFWA Golf Classic Innovation Grant 2023 (funded by Cystic Fibrosis Western Australia)
Project Title: In-silico Artificial Intelligence Platform for Bacteriophage Therapy
Principle Investigator: Yuliya Karpievitch
Institution: Telethon Kids Institute
Value: $37,750
Duration: 1 year
Summary: Bacterial antibiotic resistance is a growing problem and patients with cystic fibrosis are at higher risk of acquiring antibiotic resistant pathogens in their lifetime. Phages are viruses that infect and are able to kill bacteria without infecting the patient. Thus, phage therapy has a great antibacterial treatment potential. However, rapid and highly accurate matching of phages to the specific patient’s bacteria is currently done using labour-intensive laboratory methods that take several days. We will implement an artificial intelligence-based method to quickly and accurately identify a personalised phage cocktail, a collection on phages best suited to kill patient’s bacteria. Such method will allow for a rapid phage therapy delivery for cystic fibrosis patients with multi-drug resistant bacteria.

Project Title: Establishing the utility of GCTM-5 as a biomarker for liver pathology in cystic fibrosis patients
Principal Investigator: George Yeoh
Institution: Harry Perkins Institute for Medical Research
Value: $48,722
Duration: 1 year
Summary: Cystic fibrosis affects 1 in 2,500 babies and mainly affects the lungs, but liver disease can add to their poor health. About a third of patients develop serious liver disease. Current blood tests to identify them are unreliable and only work when liver disease is well advanced. Sampling a tiny piece of liver is the best way to tell, but it is an invasive and complicated procedure, expensive, and not possible to do repeatedly. This project aims to get around this problem by developing a new blood test that tells us whether liver stem cells are present. Stem cells grow in diseased liver to repair it. In other liver diseases we found that the amount of liver stem cells can tell us about the condition of the liver. If there are a lot, then the liver is very sick. Therefore, the blood test would measure the amount of bits of the stem cell in patients with cystic fibrosis and inform us of the condition of their liver. This blood test could then inform doctors which patients are developing early liver disease and should undergo treatment, and which have a serious condition and need special care to avoid liver failure.

Project Title:  Identifying molecular pathways for severe CF liver disease and predicting risk of CFTR modulators-induced liver injury using iPSC-derived hepatic organdies

Principal Investigator: Nikhil Awatade

Institution: Hunter Medical Research Insitute

Value:  $79,977

Duration: 1 year

Summary:  Liver damage is a major problem for people with cystic fibrosis (CF). Additionally, the gold standard treatment for people with CF (CF transmembrane conductance regulator [CFTR] modulators) can induce liver damage, limiting their use in people with liver disease. These medications have greatly improved CF patients’ life expectancy and quality of life and limiting their use due to pre-existing or medication-induced liver disease has severe consequences for patients. Little is known about CF liver disease due to difficulties studying the liver without invasive biopsies. To address this problem, we will use a novel technique called induced pluripotent stem cells (iPSC). This allows us to isolate and reprogram cells from blood to develop “organoid” models of liver tissue that retain the characteristics of the people from which they are derived. Using these organoids, we will assess the characteristics which distinguish CF patients with liver disease from those without liver disease, and from people without CF. We will also assess the effects of CFTR modulators on liver organoids and identify the causes underlying adverse reactions. This research will develop a non-invasive model to investigate CF liver disease and identify the cause of underlying mechanisms that can be targeted to improve patient wellbeing.

CFRL Pathways to Treat Intractable Lung Infection in CF Lung Transplant Recipients Grant (funded by Cystic Fibrosis Research Limited Queensland)

Project Title: New pathways to treat intractable lung infection in lung transplant recipients with cystic fibrosis

Principal Investigator: Amy Pham

Institution: University of Queensland

Value: $48,074

Duration: 1 year

Summary: Lung transplantation is an invaluable medical procedure that is often the only hope for cystic fibrosis (CF) patients with end stage lung disease. Today in Australia, lung transplantation saves and breathes new life into more than 160 patients a year. However, despite significant advances over recent decades median survival remains unacceptably low at around 5 years. Microbial infection, particularly by Pseudomonas aeruginosa, is one of the key drivers associated with lung dysfunction and rejection post transplantation. Infection is difficult to manage clinically as many are intrinsically resistant to many antibiotics. Our research has identified a specific type of antibody that instead of protecting against infection, actually cloaks and protects the bacteria from immune killing. Termed ‘cloaking antibodies’ when removed restore killing of the bacteria without the need for antibiotics. This research aims to expand the relevance of cloaking antibodies to other common lung pathogens, including Burkholderia spp. which often means lung transplantation is not an option in CF patients.

Cystic Fibrosis WA Post Graduate Top Up Scholarship (funded by Cystic Fibrosis Western Australia) 

Project Title:  Assessing aerosolised bacteriophage to treat antibiotic resistant bacterial infections

Principal Researcher:  Rohan Flint

Institution:  University of Australia/Telethon Kids Institute

Value: $37,500

Duration: 3 years

Summary:  P. aeruginosa is a prominent respiratory pathogen that is becoming resistant to an increasing number of antibiotics. With antimicrobial resistance (AMR) emerging in many bacterial pathogens at an alarming rate and the number of effective anti-microbial drugs diminishing, novel treatment methods are urgently needed. Phage therapy remains a promising alternative and adjunct to current antibiotics. One aspect to consider for phage therapy is the delivery method, which will vary depending on where infection occurs. Nebulisation and inhalation of bacteriophage remains the preferred approach for AMR respiratory infections, as this enables the delivery of phage(s) directly to areas of bacterial colonisation. However, little is known of the effects of aerosolisation on the stability and function of phages, and this is further complicated by the fact that phage stability varies across individual species. This project will hence assess the effects of aerosolisation on phage viability and resulting activity. Furthermore, identified phage(s) that remain infective after aerosolisation, will then be used to create phage suspensions for preclinical inhaled delivery assessment. Using human cells, we will establish a 3-dimensional model of the airway. We will then establish P. aeruginosa infections and assess the effects of aerosolised phage delivery on bacteria as well as host airway responses

Conquer Cystic Fibrosis Lung Health Transplant Grant (funded by Conquer Cystic Fibrosis) 

Project Title: Transforming diagnosis of lung transplant rejection

Principal Investigator: Herbert Ludewick

Institution: Health and Lung Research Institute, WA

Value: $50,000

Duration: 1 year

Summary: Lung transplant is a transformative therapy for those patients with end stage CF lung disease. Despite this, half of all lung transplant recipients will die within 6-7 years mainly due to the cumulative effects of the patient’s body rejecting the donor lungs in spite of powerful medications to suppress this normal immune response. Accurate diagnosis of lung rejection episodes and timely treatment can lengthen healthy survival for CF patients receiving lung transplantation. At present screening for and diagnosing rejection requires regular sampling of the lungs themselves requiring general anaesthesia and the risk of lung collapse and serious bleeding. It is known that during rejection, more lung DNA is released into the blood. Our project aims to find a signature specific to DNA from the lung and test for it in the blood. In this way a blood test will be able to more accurately and simply, diagnose lung rejection, eliminating the need for, and risks of, regular lung biopsy in transplant recipients. We believe that transforming the diagnosis of lung rejection in this way, will significantly improve the quantity and quality of CF patients who have undergone lung transplantation.

Project Title: Improving detection and assessment of lung disease in young children with cystic fibrosis

Principal Researcher: Tamara Blake

Institution: University of Queensland

Value:  $80,000

Duration: 1 year

Summary:  In Australia, one in 2,500 babies are born with cystic fibrosis (CF). lrreversible damage to their lungs begins very early in life and often without any symptoms. A significant limitation to early disease detection in patients with CF has been the lack of safe and sensitive measures suitable for use in infants and toddlers. Currently, the only methods available to monitor lung changes is performed under sedation in specialised laboratories. This is often a traumatic experience for patients and their families. We propose to assess the appropriateness of a new, innovative technique that can easily and reliably measure lung function in very young children. Oscillometry can be performed during quiet sleep and is very sensitive to early changes in the CF lung. Results from this pilot study will inform future study designs that will aim to better understand the mechanisms of early CF lung disease and better define the role of new sensitive measures that can monitor disease progression. Use of this technique in this population will also provide parents and physicians with detailed lung health information much sooner than current methods.

Duration: 1 year

Summary:  The aim of this study is to determine whether in adults with stable CF, a single treatment session using the MetaNeb® produces greater change in measures of secretion clearance and lung oxygenation using fMRI and other measures of lung function compared to normal huff and cough.  We hypothesise that the treatment session that includes the use of the MetaNeb® device will produce greater changes in these measures, when compared with the treatment session that comprises huff and cough alone.

Project Title:

Australian-wide surveillance for fungal infection: A national metagenomic analysis across 19 CF centres

Principal Investigator: Steven Taylor

Institution: South Australian Health & Medical Research Institute

Value:  $80,000

Duration: 1 year

Summary:  Lung infections associated with cystic fibrosis (CF) are devastating. They contribute to both everyday breathlessness as well as the acute lung events. The microbes that cause these lung infections are under constant pressure to adapt and change to the treatments that doctors prescribe to try and eradicate them. Over the last few years, several revolutionary changes have been made to how people with CF are treated. We are already seeing that the main bacteria associated with CF lung infections are declining because of these therapies. However, previously when we see changes to the microbes that cause lung infections, we see emergence of new microbes. This poses great risks as treatment plans for these new microbes are less established. My research will investigate the lung “microbiome” of over 900 samples already collected from people with CF across Australia. This will include looking at the fungi in the lungs, which are often overlooked, but which are known to become more common following changes to treatment. By looking at samples collected before and after starting new treatments, we can identify key microbes to monitor, giving us the best chance to protect people with CF from new infections.

ACFRT Top Up Scholarship

Project Title: The impact of helpful and harmful immune responses in the CF lung

Principal Researcher: Emma Ledger

Institution: University of Queensland Diamantina Institute

Value:  $15,000

Duration: 3 years

Summary:  Pseudomonas aeruginosa is a highly multi-drug resistant bacteria which causes chronic lung infections in individuals with cystic fibrosis (CF). This bacterium is extremely difficult to eradicate and is a major cause of morbidity and mortality in CF. Our research investigates specific antibodies produced by patients that enhance, rather than clear these bacterial infections resulting in further disease burden.  This project aims to better understand the prevalence, impact, and mechanisms of these ‘bad antibodies’ in individuals with CF by characterising them for the first time within patient sputum and towards the patient’s infecting strain. Additionally, we aim to investigate the impact the latest CF transmembrane conductance regulator (CFTR) modulator therapies have on P. aeruginosa infection and these dysregulated antibody responses. This research is critical for the development of targeted therapies to neutralise these ‘bad antibodies’, clear persistent multi-drug resistant lung infections and improve patient outcomes further in this post-modulator era.

Project Title: Neutrophils in CF

Principal Investigator: Luke Garratt

Institution: Telethon Kids Institute/University of Western Australia

Value:  $28,000

Duration: 1 year

Summary:  In cystic fibrosis (CF), neutrophils accumulate in areas of the lung as mucus builds up and germs infect the airways. My research has found that in CF airway inflammation, neutrophils choose to actively release their harmful products rather than trying to eat and kill the germs causing infection. In a laboratory model of CF airway inflammation, we have found that only certain germs induce this behaviour. We are now studying how the gene expression of neutrophils determines their function, with the aim to understand whether we can prevent certain functions by inducing or repressing genes within the neutrophil. This CFWA funded project is exploring the ability of new nanoparticle technologies to modify gene expression in neutrophils, as neutrophils are short-lived cells that do not respond to traditional methods. The hope is that this technology could inform a new class of anti-inflammatories for controlling neutrophil behaviour in CF airways.

Project Title: The road map to personalised diet management in children with cystic fibrosis

Principal Researchers: Hiran Selvadurai and Andrea Kench

Institution: The Children’s Hospital, Westmead

Value:  $5,000

Duration: 1 year

Summary:  We  know that people with cystic fibrosis (CF) need more energy from food to grow and fight infections than healthy people. However, there is very little information available on specific macronutrient (carbohydrate, protein and fat) requirements for children with CF. In particular, it is not known how macronutrients contribute towards fueling the body during periods of rest and during exercise. This information is needed so that we can implement personalised nutritional goals. This is particularly important in the context of new CF treatments (modulator medications) which have led to a significant improvement in lung function, weight and quality of life. Further, significant infections such as NTM is a growing problem in patients with CF but it is not clear how these infections impact on macronutrient use and energy expenditure in children with CF. Exciting new technologies now enable us to quantify nutritional macronutrient requirements for children. The purpose of this research study is to ascertain if we can determine macronutrient requirements for children with CF.

Project Title: Progressing novel treatment options to improve management of infections in people with cystic fibrosis

Principal Researcher: Stefanie Bader

Institution: Walter & Eliza Hall Institute of Medical Research

Value:  $10,000

Duration: 1 year

Summary: Bacterial infection is the most common cause of death in people with cystic fibrosis (CF). The immune cells responsible for combating bacteria are often defective in CF patients and can damage the lungs and gut while trying to fight infection. This reaction worsens disease and fails to kill the pathogen. We propose to use a new class of drugs that can tackle this problem in two ways: by killing infected host cells, reducing the number of bacteria and by removing defective immune cells. This approach has the potential to improve quality and length of life in people with CF by addressing disease in the lung and the gut.  The Fellowship would provide an invaluable opportunity for me to travel to a lab in the Netherlands which specialises in CF and the gut. There, I would be able to test our drugs both in in-vivo and organoid models of CF gut disease to gain substantial knowledge on how to apply their techniques to our research at WEHI. This would allow my lab to test a greater array of drugs in Australia. I will share the techniques I learn, not just with my lab at WEHI, but with other CF researchers in Australia.

Project Title: Establishing a pipeline for repurposing anti-inflammatory drugs to tackle viral-induced exacerbations in children with cystic fibrois.

Principal Investigator: Samuel Montgomery

Institution: Curtin University/Telethon Kids Institute

Value:  $50,000

Duration: 1 year

Summary:  This study aims to improve the lung health of young children with cystic fibrosis (CF) following a viral infection. Rhinovirus infection (the “cold” virus) is common in young children, often resulting in presentation to hospital emergency departments. This is worsened in children with chronic airway disease such as the inheritable disease cystic fibrosis (CF) where infection with rhinovirus results in deteriorating lung health, sadly often permanently, leading to chronic bacterial infection and increased hospitalisation. Rhinovirus infects the cells lining the airway (the “epithelium”) provoking a large inflammatory response, which can lead to lung damage. We have previously identified a specific type of inflammation which is associated with decreasing lung health in children without bacterial infection. We propose to block this inflammation using a drug, interleukin-1 receptor antagonist, as a new anti-inflammatory treatment for the cold virus in children with CF. We will use a model of the airway in the laboratory to test the safety and effectiveness of this drug to reduce this inflammation. This study aims to provide evidence to progress to a clinical trial, as this drug is already approved for use in other diseases and could be rapidly translated into clinical use for children with CF.

Project Title: Does a diagnosis of Tracheobronchomalacia affect health outcomes in children with cystic fibrosis?

Principal Researchers: Julie Depiazzi and Crystal Bourke

Institution: Perth Children’s Hospital

Value:  $5,000

Duration: 1 year

Summary:  Around 41% of young children with cystic fibrosis (CF) in Western Australia have been reported to have tracheobronchomalacia (TBM) seen during bronchoscopy – a condition where parts of the windpipe or airways are floppier than would be considered normal. In the short-term this TBM finding can lead to a change of the child’s daily physiotherapy and airway clearance program, however despite its prevalence, little is known about the long-term impact of TBM. 

The aim of this study is to compare health outcomes of children with CF, both with and without TBM, up to the age of 4 years, and will include imaging, inflammation markers and infection comparisons. We hope our findings will provide clinicians and families with more insight into, if any, long-term impacts of this condition.

Project Title: Short Chain Fatty Acids and Gastrointestinal complications in cystic fibrosis

Principal Investigator: Josie van Dorst

Institution: University of New South Wales

Value:  $50,000

Duration: 1 year

Summary: Cystic fibrosis (CF) is a life-shortening genetic condition, which causes thick mucus, chronic infection, and inflammation not only in the lungs but also the gut. People with CF also have an imbalance between beneficial and harmful gut bacteria, which are linked to poor growth, gut symptoms, chronic gut inflammation and increased cancer risk. Short chain fatty acids (SCFA) are produced by beneficial bacteria in the gut, mainly from prebiotic dietary fibres. SCFAs fuel the activities of beneficial bacteria and have many important roles in the gut and wider health, including combating inflammation and cancer activity, and regulating the communication with the lungs (gut-lung axis) and the immune system. Despite this, there is limited knowledge regarding SCFA in individuals with CF.

Principal Researcher: Andrew Vaitekenas

Institution: Curtin University

Value:  $37,500

Duration: 3 years

Summary:   Psuedomonas aeruginosa causes harmful lung infections in CF lungs and becomes resistant to existing antibiotic treatments. There is a lack of antibiotics being developed and alternative treatments are needed. A therapy using viruses that specifically kill bacteria is effective, but P. aeruginosa can become resistant to this too. My project aims to understand how P. aeruginosa becomes resistant to phages and what this means for the bacteria. I will use this knowledge to develop and test strategies that increase the effectiveness of phage therapy and prevent resistance occurring. These strategies can aid our group in making phage therapy a regularly used therapy, preventing further resistance and treating those with infections that are currently untreatable.

Summary:   The recent approval of the novel CFTR modulator triple combination Trikafta targets the majority of cystic fibrosis (CF) patients, but potentially excludes pregnant women as the clinical efficacy of these important drugs is limited by our lack of understanding what short and long-term effects these drugs could have on developing babies. This project will investigate the entry of the triple combination across the placenta in an animal CF model that replicates a common CF mutation. The project will also assess the potential of maternal administration of these drugs to reduce the amount of CF damage occurring before birth. This innovative approach has significant potential in improving clinical practice worldwide.

Project Title: Sphingosine-1 phosphate and zinc – novel mediators of vascular dysfunction in children with CF

Principal Investigator: Andrew Tai

Institution: The University of Adelaide

Value:  $50,000

Duration: 1 year

Summary:  Increased lung artery blood pressure in cystic fibrosis (CF) is linked to poorer survival. Treatment is ineffective as diagnosis usually occurs in adulthood, when the disease is at a later stage. Current CF paradigms are based on the assumption that there is no or minimal lung disease in newborns with CF, and prevention therapy in early childhood has not therefore been considered. We propose a substantial shift in this current paradigm: that there is progression of vascular dysfunction in parallel with the gradual progression of lung disease through childhood in CF and that prevention/intervention therapies before measurable disease would provide a new therapeutic approach. Based on findings by us and others of a role for arterial zinc and sphingosine-1 phosphate (S1P) in cardiovascular disease and a link between zinc and S1P in the vasculature we will investigate blood/ airway samples from children (and adults as controls) with CF, and lungs from CF rats. Long-term treatment with macrolide antibiotic is being increasingly used in CF; however, they this is now known to result in the emergence of antibiotic resistant bacterial strains. We will test a novel non-antibiotic macrolide to address the global priority of halting the generation of further antibiotic resistant bacteria, a profound problem that is one of the biggest threats to global health today.

Project Title: Designing optimal phage cocktails for kids with cystic fibrosis (DOCK-CF)

Principal Investigator: Ameneh Khatami

Institution: University of Sydney

Value:  $50,000

Duration: 1 year

Summary:   To manage chest infections, children with cystic fibrosis (CF) are exposed to broad-spectrum, toxic antibiotics several times per year. This is only moderately effective, with infections often becoming increasingly difficult to treat due to evolving antimicrobial resistance. Bacteriophages (phages) are viruses that replicate within bacteria, causing highly selective bacterial killing. Since phages do not attack human cells they are safe for clinical use, and their targeted bacterial killing reduces their impact on our healthy microbiome (commensal bacteria). Thus, phage therapy offers a safer and more precise solution than antibiotics.We hypothesise that Pseudomonas aeruginosa and Staphylococcus aureus strains that colonise children with CF can be eradicated effectively by combinations of phages (“phage cocktails”). This would result in reduced lung damage and allow recovery of normal lung growth, improving the life expectancy of children with CF. In addition, reduced toxicity and microbiome effects compared to antibiotics would improve quality of life for patients and their families. This proposal aims to identify phages with ‘killing’ activity against the main strains of these bacteria isolated from a large cohort of children with CF.  Research outcomes will feed into a translational pipeline to investigate this promising therapy in children with CF within 5 years.

Project Title: Me, myself and I: An exploratory study of self-concept in adults with Cystic Fibrosis (CF) in an evolving era of care.

Principal Researcher: Maggie Harrigan

Institution: University of Western Australia

Value:  $37,500

Duration: 3  years

Summary:   The PhD study explores self-concept (sometimes called self-identity) e.g. how you view yourself, a sense of who you are as a person in the various aspects of life. Outside CF, self-concept has been widely associated with improved health, however there is currently a lack of self-concept research within CF. I will be examining levels of self-concept within the adult CF community and associations between self-concept, mental, social and physical health. The study will also explore the potential impact of evolving CFTR modulator treatments on self-concept.  As CF treatments evolve, what is means to have CF continues to change, potentially bringing new opportunities and challenges.  Amidst this change it is pertinent to develop our understanding of the social and emotional needs of those living with CF.

Ann Maree Bosch Fellowship

Project Title: The Gut-Lung Axis in early cystic fibrosis (GLAX-CF)

Principal Researcher: Katherine Frayman

Institution: Murdoch Children’s Research Institute

Value:  $9,500

Duration: 1 year

Summary:  My research explores the development of the gastrointestinal and lower airway microbiota during the first two years of life in newly diagnosed infants with cystic fibrosis, and their relationship to each other, to lower airway inflammation and to clinical manifestations of disease. It will examine the impact of continuous antibiotic prophylaxis on the microbial milieu in both niches, and its relationship to clinically relevant outcomes. Ultimately, my research aims to highlight opportunities for intervention, for example, modification of the gastrointestinal microbiota with pro-, pre- or antibiotics, in order to influence respiratory phenotype. The Ann Maree Bosch Career Fellowship will enable me to travel to the United States to establish key collaborations with the University of Washington and Seattle Children’s Hospital, Washington and attend the North American Cystic Fibrosis Conference.

Project Title: Towards understanding gut host-microbe interactions and personalised probiotic therapy in cystic fibrosis using organoid-derived 2D intestinal models

Principal Investigator: Keith Ooi

Institution: University of New South Wales

Value:  $50,000

Duration: 1 year

Summary: Cystic fibrosis (CF) is a life-shortening genetic condition, which causes thick mucus, chronic infection, and inflammation in the lungs and gastrointestinal (GI) tract. People with CF have an imbalance in their GI bacterial population (microbiome) known as “dysbiosis”, and chronic GI inflammation, both of which are linked to poor growth, GI symptoms and increased cancer risk. A survey of CF patients and clinicians globally has ranked GI symptoms 2nd in priority, ahead of respiratory issues, yet no GI-specific therapies currently exist. Stem cells obtained from gut biopsies from people with CF can be used to grow 2-dimensional and 3-dimensional organoid culture systems which replicate real life (“mini guts”). We will investigate the host-microbe interactions involved in GI dysbiosis, inflammation and malignancy, using CF patient-specific intestinal organoids. We believe this study will provide a crucial step towards personalised therapies based on host-microbe interactions with the aim of reducing GI complications in CF. Successful personalised therapies would revolutionise CF treatments and other conditions subject to host-microbe interactions.

Project Title: Enhancing the innate ability of CF macrophages to kill and clear MABS

Principal Investigator: Abdullah Tarique

Institution: University of Queensland

Value: $80,000

Duration: 1 Year

Summary: Currently 13-20% of patients with CF are infected with Mycobacterium abscessus (MABS) and there is growing concern that increasing incidence of MABS infection is leading to accelerated pulmonary decline, and to reduced survival. MABS are notoriously difficult to treat, in part because of widespread antibiotic resistance, thus necessitating the use of toxic drug regimens. We herein propose to evaluate an alternative approach to clear MABS by boosting the anti-bacterial responses of CF patients using novel therapeutic agents. Macrophages are the professional killer cells that kill bacteria including MABS from the lungs. Sputum and venous blood are the two main sources for macrophage researchers. Due to inadequate volume of patient’s specimen available for research, macrophage researchers struggle in getting enough macrophages from patients’ specimen which thereby limit macrophage research in CF. We herein propose to develop an immortalized CF macrophage cell line that will offer indefinite supply of CF macrophages to the researchers to investigate macrophage defect in CF as well as finding out ways to improve their anti-microbial responses in CF.

Project Title: Targeting a forgotten cell to prevent cystic fibrosis lung disease

Principal Researcher: Shivanthan Shanthikumar

Institution: Murdoch Children’s Research Institute

Value: $9,000

Duration: 1 year

Summary:  The life expectancy for someone born with cystic fibrosis (CF) today is only 44 years. In CF the major cause of shortened life expectancy, as well as reduced quality of life, is lung disease. A major cause of lung disease in CF is excessive inflammation which causes to irreversible lung damage. Currently a number of treatments are used in CF such as antibiotics and chest physiotherapy, however no treatments target inflammation. There are new treatments which address the malfunctioning ion channel which causes CF, however these treatments only target specific certain genetic mutations, and so not all patients benefit from them. Any treatments aimed at inflammation in CF would benefit all patients, and could be used together with existing and new treatments. There are a number of different cell types that contribute to inflammation, however one that has not been investigated is the alveolar macrophage. These cells only exist in the lung and are one of the initial cells that trigger an inflammatory response. There are multiple types of alveolar macrophages in CF lungs, and thus far they have not been studied. The overall aim of my research is to identify targets for treatment relating to alveolar macrophages.

Project Title:  An Australian Alliance of personalised lab grown mini-organs to save the rarest of them all

Principal Investigator: Shafagh Waters

Institution: University of New South Wales

Value: $45,000

Duration: 1 Year

Summary: Some individuals with rare CFTR mutations have been shown to benefit from the available modulator therapies. Sadly, most will have no opportunity to access these breakthrough treatments. Currently no clinical test exists to predict patient’s response to a modulator drug. We are using a new technology in the field of personalised medicine. Stem cell derived mini-organs are generated from small biopsies serving as a personal CF model or an AVATAR. They are tested in the lab to predict an individual CF patients’ responses to therapeutic agents. Should one or more therapies prove effective in the lab, these can be recommended for use as targeted therapies for the patient.

In the last 2 years we have created AVATARs from children with CF that visit the Sydney Children’s Hospital and have predicted outcome of modulator therapies. In this application we propose to extend our platform to create an Australian-wide alliance for people with rare CF by extending to 11 CF clinics (6 paediatric and 5 adult). This project will provide a novel therapeutic opportunity, ultimately enabling ‘managed’ off-label access to the CFTR modulator therapies for individuals with rare CFTR mutations who show response to the therapy in a prospective mini-organ test.

Project Title: Optimising patient-derived stem cell technology in cystic fibrosis to predict CFTR modulator response

Principal Investigator: Gerard Kaiko

Institution: University of Newcastle and Hunter Medical Research Institute (Newcastle and Northern NSW)

Value: $80,000

Duration: 1 Year

Summary: CFTR modulator therapy offers great hope to improve the quality of life of cystic fibrosis (CF) patients with an array of different mutations. However, the high-cost, limitations of efficacy, and restrictions of therapies to clinical trial targeted mutations has created a powerful need for a lab test to better predict which CFTR mutations and which individual patients will respond to a given therapy. This type of precision-medicine is already critical but will only become more vital in the future as CFTR modulator therapy options increase. Stem cell technology has enabled patient cells to be readily grown in the laboratory. The use of ‘mini-guts’, grown from a CF patient intestinal biopsy, is being used in the Netherlands to suggest whether a given CFTR mutation may respond to a given therapy. To enable this type of testing to be put into practice in Australia there are two major questions that we aim to address in this project. Firstly, what is the optimal stem cell technology and functional test to apply to patient cells to determine whether they will respond to therapy. Secondly, can we predict a patient’s response to CFTR therapy in the clinic by testing the drugs on their stem cells.

Project Title: Colorectal Cancer

Principal Investigator: Keith Ooi

Institution: University of New South Wales

Value: $50,000

Duration: 1 Year

Summary: Adults with cystic fibrosis (CF) now face new complications such as colorectal cancer (CRC). The cause is unknown but gut inflammation and gut bacteria imbalances are possible causes. The risk for CRC in CF is high enough that new CRC screening guidelines recommend colonoscopy for patients >40 years and for post-transplant patients >30 years old. Performing colonoscopies in adult CF patients is complex due to comorbid diseases including poor lung function and diabetes. Non-invasive screening tests are needed, similar to faecal occult blood testing (FOBT) used for general population screening. While FOBT utility in CF remains unclear, other stool tests for gut inflammation (calprotectin and M2-PK) have shown promise in detection of CRC and polyps in the general population. They are elevated in children with CF and may be potential early markers of future CRC in adults with CF. To investigate this further, we will invite patients who meet criteria for CRC screening to provide stool samples prior to their scheduled colonoscopies. Markers of gut inflammation including calprotectin and M2-PK, FOBT and imbalances in gut bacteria will be assessed and compared with incidence of CRC and number of adenomas. Predictors for colorectal cancer and precancerous lesions will also be assessed.

Project Title: Adverse Early Risk Factors for Adult Cardiovascular Disease in Paediatric Cystic Fibrosis

Principal Researcher: Thomas Saunders

Institution: Murdoch Children’s Research Institute

Duration: 3 years

Value: $5,000

Summary: Life with cystic fibrosis (CF) has undergone dramatic changes over the past decades, thanks to early interventions throughout childhood, including a high fat diet. Unlike previous generations, current CF children are living beyond their twenties, and now into their fifth or sixth decades. However the new medical challenges they will face are largely unknown. In particular, the impact of the leading causes of death worldwide, atherosclerosis and cardiovascular disease (CVD- heart attack and stroke), are unknown. Lung diseases similar to CF have much higher risks of CVD than the general population and there are increasing case reports of CF individuals developing CVD.

Atherosclerosis (hardening of the arteries) is thought to be largely preventable, especially when intervention starts in childhood. Risk factors such as inflammation, metabolic stress, and abnormal fat metabolism are all found in people with CF; but they are also prescribed high-fat diets, necessary to maintain good weight gain and growth. As CF life expectancy improves, and there are more and more instances of CVD in CF adults, novel studies aiming to detect it will be crucial.

This study investigates if CF children have early changes to blood vessels, biomarkers and immune system that may lead to atherosclerosis and CVD in adulthood. We will perform non-invasive ultrasounds looking at arteries, assess smaller vessels with retinal photographs, and measure specific biomarkers and immune cells in the blood.

This study is expected to show that CF children do have changes that suggest they may be at higher risk of atherosclerosis and CVD in the future. This will indicate if our current nutritional goals are sufficient, and guide changes to minimise the impact of CVD in CF adults. As people with CF live longer, it is critical that their increased survival also has improved quality of life with any treatment side-effects minimised. As such, this study will have a direct impact on how we treat people with CF in the future.

Project Title:  Does the MetaNeb®, a new airway clearance device, change lung function in adults with cystic fibrosis when they are well and when they are hospitalised for a lung infection?

Principal Researcher: Naomi Chapman

Institution: Curtin University

Value:  $37,500

Duration: 3 years

Summary:  Cystic fibrosis (CF) is an inherited lung disease that causes excessive airway secretions, damaging airways and leading to chronic infection. Clearing the airways is a vital component of their care and is believed to reduce lung infections and slow disease progression. Although there are a range of techniques used to clear airway secretions, there is no evidence to support one over others. Therefore, the choice of technique is based largely on patient/therapist preference. This project will look at the effects of a new airway clearance device called the MetaNeb®, on lung function, secretion clearance and CF related symptoms in adults with CF who are well and those hospitalised with a respiratory exacerbation or chest infection. If this device is shown to be more effective than the commonly used techniques, this would be of great clinical significance as it will assist in guiding clinical use of the device throughout CF centres in Australia and internationally.

Project Title: Infection Control and prevention with non-invasive ventilation use

Principal Researcher: Olivia McGuiness

Institution: Royal Prince Alfred Hospital

Value: $5,000

Duration: 1 year

Summary: Infection control and prevention is of paramount importance in the health care setting. The National Health and Medical Research Council in collaboration with the Australian Commission on Safety and Quality in Healthcare emphasize the importance of standard and transmission-based precautions (NHMRC, 2010). Recommendations for infection control and prevention are outlined for several commonly used medical devices including central venous catheters and mechanical ventilators used in the intensive care. There are no such guidelines for non-invasive ventilator (NIV) devices. Due to its high costs, patients usually obtain these devices from a hospital or government equipment loan program. NIV devices are used or the management of patients with acute and chronic respiratory failure including those with chronic obstructive lung disease (COPD), sleep disordered breathing and suppurative lung diseases, like Cystic Fibrosis (CF).
