Safety and efficacy of nebulized phage in CF patients with chronic Pseudomonas aeruginosa pulmonary infection: A phase 1b/2a randomized, double-blind, placebo-controlled, multicenter study (257 AB) - Jul 4, 2024 - Abstract #NACFC2024NACFC_640; This randomized, double-blind, placebo-controlled, multicenter study evaluated nebulized BX004-A in 43 outpatient adults with CF with clinically stable lung disease (FEV1 ?40%) and chronic P. aeruginosa pulmonary infection taking inhaled antibiotics (tobramycin, aztreonam, or colistin) with sputum P. aeruginosa of ?105 CFU/g, and with all screening P. aeruginosa morphotypes susceptible to one or more phages in BX004-A... BX004-A showed favorable safety and notable microbiologic and clinical efficacy in Part 2, with more-pronounced microbiologic reduction than in Part 1.

Evaluating serum lipid changes after Ivacaftor initiation in the GOAL study (206 AB) - Jul 4, 2024 - Abstract #NACFC2024NACFC_634; We speculate that this may be due to dietary modifications made by patients in response to weight gain on ivacaftor (average BMI increase of 1.4 kg/m2 from baseline at 18 months) or other factors that over time diminished the initial change in TC. Continued rise in lipids was not observed after the 3-month time point.

Longitudinal changes in bone mineral density in adolescents and adults with cystic fibrosis on elexacaftor/tezacaftor/ivacaftor (104 AB) - Jul 4, 2024 - Abstract #NACFC2024NACFC_629; Despite the well-recognized systemic benefits of ETI, aBMD decreased by about 0.2 standard deviations in adolescents over the 24-month follow-up period but remained stable in adults. The potential impacts of ETI when initiated at young ages on bone strength, fracture risk, and adolescent bone accretion remain undefined but will be important considerations in screening and management guidelines.

Bioengineered 3D CF lung airway model for drug testing (Theater A (Exhibit & Poster Hall)) - Jul 4, 2024 - Abstract #NACFC2024NACFC_590; Our findings demonstrate that this novel model not only enables fabrication of human lung airway-like structures in vitro that mimic in vivo physiology, but also facilitates qualitative and quantitative measurement of patient-specific MCC and determines pharmacological effects. Our results suggest that this model is a valuable tool for understanding mechanisms underlying impaired MCC and testing the efficacy of novel therapeutic strategies for treatment of respiratory diseases such as CF.

Targeting cellular senescence in the cystic fibrosis lung. (Theater A (Exhibit & Poster Hall)) - Jul 4, 2024 - Abstract #NACFC2024NACFC_584; Senolytic treatment can reduce senescence markers and restore mucociliary clearance, and infection with P. aeruginosa can further exacerbate senescence in CF. Therefore, this study proposes cell senescence as a pathomechanism in the CF lung and that senolytics are a potential novel therapy for all PwCF independent of their CFTR modulator eligibility.

Role of pharmacogenomics in lung transplant with CF and Elexacaftor/Tezacaftor/Ivacaftor therapy (109 AB) - Jul 4, 2024 - Abstract #NACFC2024NACFC_581; Simplified and accessible pharmacogenomic data would augment clinical decision making in accounting for the influence of drug response along with existing consideration of all nongenetic factors. We hope to expand this work to include most of our CF LTx patient registry and to study effects on full pulmonary function, symptom score with the Cystic Fibrosis Questionnaire-Revised, impact on drug dosing, infection rate, diabetes mellitus control, and chronic rejection in these individuals.

It will be important to monitor this population to ensure updated and realistic expectations, particularly regarding survival estimates.

Microenvironmental effects of a non-antibiotic therapy for a chronic airway disease modulate the virulence of its principal pathogen (156 A-C) - Jul 4, 2024 - Abstract #NACFC2024NACFC_546; A revolutionary therapy, elexacaftor/tezacaftor/ivacaftor (ETI), has improved mucociliary clearance and lung function and decreased infection in PwCF... These findings indicate that ETI not only benefits PwCF through improvement in lung function [2, 3], but may also reduce the virulence of its principal pathogen and highlight how the forces of microbial ecology can modulate polymicrobial infections through the modifications of microenvironmental chemistry.

Given the high cost of therapy, there is a risk of widening disparities in CF outcomes in the upcoming years in the absence of targeted interventions to ensure access to this life-saving treatment in resource-limited countries.
