Summary
The introduction of triple combination CFTR modulator therapy for patients with Cystic Fibrosis (CF) with at least one copy of the deltaF508 mutation is expected to provide major health benefits, but will also require novel outcome measures that can detect CF lung disease at an early stage, capture the efficacy of new therapies when disease manifestations are limited, as well as determine whether stopping existing chronic maintenance therapies does not have negative effects.
In the past decade, research has focused on the multiple breath washout (MBW) test, as a sensitive outcome measure, especially if highly-effective modulator therapies are initiated in early childhood. Even LCI, however, may not adequately capture early lung function changes, thus warranting investigation of even more sensitive outcome measures.
Magnetic resonance imaging (MRI) has the advantage of being a radiation-free modality, making it more suitable for assessing response to therapy in a shorter time frame with repeated imaging. Inhalation of a hyperpolarized gas enables the visualization and quantification of regional ventilation in the lung and can be combined with structural MRI to assess both structure and function in parallel.
The main Investigator and others have recently formed an international consortium (the 129Xe MRI Clinical Trial Consortium), comprised of both imaging experts and pulmonary clinicians to standardize imaging procedures, thus facilitating multi-site implementations. Data from this proposed study (HyPOINT; Hyperpolarized Imaging for New Treatments) will inform the future utility of MRI for both longitudinal studies to track disease progression over time as well as for future interventional trials. Further, the current study could inform the design of future trials of interventions of patients for whom currently no effective CFTR modulator therapy is available and for patients with rare genotypes thus laying the groundwork for a more personalized medicine approach in the near-term future.
Description
The HyPOINT (HyperPOlarized Imaging for New Therapies) trial is a multicenter prospective, two phase study involving four sites with proven expertise 129Xe MRI and CF clinical care. The study sites are: University of Virginia, University of Wisconsin, and SickKids in Toronto, Canada. University of Virginia and University of Wisconsin sites will be reliant on CCHMC's IRB. SickKids in Toronto, Canada, will submit their review through their institution's Research Ethics Board (REB).
Phase 1 will include implementation of a centralized analysis program of repeated 129Xe MRI scanning in CF patients with mild lung disease to define the intra-subject variability of the primary outcome ventilation defect percentage (VDP). Patients will undergo baseline 129Xe MRI scanning and repeated measurements the same day, as well as at 28 days ( 7 days). Phase 1 will establish the intra-subject reproducibility to facilitate future use of 129Xe MRI in multi-site studies. Furthermore, the reproducibility limits defined will inform the overall design of future studies and will compare to established pulmonary function and multiple-breath washout testing (via measurement of the lung clearance index, LCI).
Safety of 129Xe MRI will be assessed by recording adverse events during the study visit (see 8.3 Adverse Events and Serious Adverse Events), which will be followed until resolved. Vital signs (heart rate, SPO2) will be recorded before, immediately following inhalation, and 2 minutes after each 129Xe inhalation; O2 saturation will be monitored continuously throughout the 129Xe portion of the MRI, and the time and duration of nadir will be recorded.
Phase 2 will be an observational study of patients assessed before and after the clinical initiation of triple-combination modulator therapy (after presumed FDA and Health Canada approval). The primary endpoint for Phase 2 is the change of VDP after 28 days of triple-combination modulator therapy. Within Phase 2, this study will also address how highly-effective modulator therapies affect lung function trajectories by measuring 129Xe MRI at 28 days ( 7 days), 6 months ( 28 days), and 12 months ( 28 days) after start of therapy (paralleling time points of the PROMISE study). Finally, to understand how 129Xe MRI can be used in combination with existing measures of lung function (e.g. spirometry, multiple breath washout), Investigators will directly compare the repeated data collected in both Phase 1 and Phase 2 to these established measures of lung function that are currently used in observational and interventional studies.
The overarching goal of this study is to define the role of structural and functional MRI imaging to facilitate future CF research studies.
