We have developed a novel lentiviral vector, pseudotyped with the F and HN proteins from Sendai virus (rSIV.F/HN), which produces long-lasting, high efficiency transduction of the respiratory epithelium. Here, we addressed whether this platform technology can secrete sufficient levels of a therapeutic protein into the lung to ameliorate a fatal pulmonary disease, as an exemplar of its translational capability. Pulmonary Alveolar Proteinosis (PAP) results from alveolar GM-CSF insufficiency, resulting in abnormal surfactant homeostasis and consequent ventilatory problems. Lungs of GM-CSF knockout mice were transduced with a single dose of rSIV.F/HN expressing murine (m)GM-CSF (1e5-92e7 TU/mouse); mGM-CSF expression was dose-related and persisted for at least 11 months. PAP disease biomarkers were rapidly and persistently corrected, but we noted a narrow toxicity/efficacy window. rSIV.F/HN may be a useful platform technology to deliver therapeutic proteins for lung diseases requiring long-lasting and stable expression of secreted proteins.

Balachandar S, Graves TJ, Shimonty A, et al., 2022, Identification and validation of a novel pathogenic variant in GDF2 (BMP9) responsible for hereditary hemorrhagic telangiectasia and pulmonary arteriovenous malformations, American Journal of Medical Genetics Part A, Vol: 188, Pages: 959-964, ISSN: 0148-7299
Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant multisystemic vascular dysplasia, characterized by arteriovenous malformations (AVMs), mucocutaneous telangiectasia and nosebleeds. HHT is caused by a heterozygous null allele in ACVRL1, ENG, or SMAD4, which encode proteins mediating bone morphogenetic protein (BMP) signaling. Several missense and stop-gain variants identified in GDF2 (encoding BMP9) have been reported to cause a vascular anomaly syndrome similar to HHT, however none of these patients met diagnostic criteria for HHT. HHT families from UK NHS Genomic Medicine Centres were recruited to the Genomics England 100,000 Genomes Project. Whole genome sequencing and tiering protocols identified a novel, heterozygous GDF2 sequence variant in all three affected members of one HHT family who had previously screened negative for ACVRL1, ENG, and SMAD4. All three had nosebleeds and typical HHT telangiectasia, and the proband also had severe pulmonary AVMs from childhood. In vitro studies showed the mutant construct expressed the proprotein but lacked active mature BMP9 dimer, suggesting the mutation disrupts correct cleavage of the protein. Plasma BMP9 levels in the patients were significantly lower than controls. In conclusion, we propose that this heterozygous GDF2 variant is a rare cause of HHT associated with pulmonary AVMs.
Edmondson C, Westrupp N, Seddon P, et al., 2022, The feasibility of home monitoring of young people with cystic fibrosis: results from CLIMB-CF, Journal of Cystic Fibrosis, Vol: 21, Pages: 70-77, ISSN: 1569-1993
BACKGROUND: CF is traditionally assessed in clinic. It is unclear if home monitoring of young people with CF is feasible or acceptable. The COVID-19 pandemic has made home monitoring more of a necessity. We report the results of CLIMB-CF, exploring home monitoring's feasibility and potential obstacles. METHODS: We designed a mobile app and enrolled participants with CF aged 2-17 years and their parents for six months. They were asked to complete a variety of measures either daily or twice a week. During the study, participants and their parents completed questionnaires exploring depression, anxiety and quality of life. At the end of the study parents and participants completed acceptability questionnaires. RESULTS: 148 participants were recruited, 4 withdrew prior to starting the study. 82 participants were female with median (IQR) age 7.9 (5.2-12 years). Median data completeness was 40.1% (13.6-69.9%) for the whole cohort; when assessed by age participants aged ≥ 12 years contributed significantly less (15.6% [9.8-30%]). Data completeness decreased over time. There was no significant difference between parental depression and anxiety scores at the start and the end of the study nor in CFQ-R respiratory domain scores for participants ≥ 14 years. The majority of participants did not feel the introduction of home monitoring impacted their daily lives. CONCLUSIONS: Most participants felt home monitoring did not negatively impact their lives and it did not increase depression, anxiety or decrease quality of life. However, uptake was variable, and not well sustained. The teenage years pose a particular challenge and further work is required.
