Abstract

Elexacaftor-tezacaftor-ivacaftor induces rapid clinical improvement in patients with cystic fibrosis (CF) and advanced pulmonary disease, often leading to suspend the indication for lung transplantation. Yet no long-term data is available in lung transplant candidates.Lung transplant candidates (defined as being waitlisted for lung transplantation or considered for listing within 3 months) who have initiated elexacaftor-tezacaftor-ivacaftor were identified in the French cohort of patients with CF and advanced pulmonary disease. Patients were prospectively followed to evaluate treatment safety and effectiveness from initiation to July 20th, 2021.Among the 331 patients with advanced CF pulmonary disease who initiated elexacaftor-tezacaftor-ivacaftor, 65 were lung transplant candidates (17 listed for transplantation, 48 considered for listing within 3 months). Median [IQR] follow-up time was 363 [329; 377] days. At the end of the follow-up period, two patients were transplanted five and 11 days following treatment initiation, two were listed for transplantation, and 61 no longer met transplantation criteria. Improvement in percent predicted forced expiratory volume in 1 s (ppFEVIn lung transplant candidates eligible for elexacaftor-tezacaftor-ivacaftor, the rapid improvement following initiation of treatment persisted over one year with a reduction in treatment burden and lung transplantation could be safely deferred in most patients.

Abstract

Background: Inhaled antibiotics have been incorporated into contemporary European and British guidelines for bronchiectasis, yet no inhaled antibiotics have been approved in the United States or Europe for the treatment of bronchiectasis not related to cystic fibrosis. Pseudomonas aeruginosa infection is common in patients with bronchiectasis, contributing to a cycle of progressive inflammation, exacerbations, and airway remodelling. Objective: The aim of the current study was to identify and evaluate published studies of inhaled tobramycin solution or powder in patients with bronchiectasis and P. aeruginosa infection not associated with cystic fibrosis. Methods: A literature review was conducted utilising the PubMed and Cochrane databases. Studies published in the English language that reported safety and/or efficacy outcomes of inhaled tobramycin either alone or in combination with other antibiotics were included. Results: Seven clinical trials published between 1999 and 2021 were identified that met inclusion criteria. Inhaled tobramycin therapy was effective in reducing P. aeruginosa microbial density in the sputum of patients with bronchiectasis. Several studies demonstrated favourable impacts on hospitalisations, number and severity of exacerbations, and symptoms. Other studies were underpowered for these clinical outcomes or were exploratory in nature. Although tobramycin was generally well tolerated, some evidence of treatment-associated wheezing was reported. Conclusions: In patients with bronchiectasis and chronic P. aeruginosa infection, inhaled tobramycin was effective in reducing the density of bacteria in sputum, which may be associated with additional clinical benefits. Definitive phase 3 trials of inhaled tobramycin in patients with bronchiectasis are indicated to determine clinical efficacy and long-term safety.

Abstract

International audience; Background: The orally available kinase inhibitor R-roscovitine has undergone clinical trials against various cancers and is currently under clinical evaluation against Cushing disease and rheumatoid arthritis. Roscovitine displays biological properties suggesting potential benefits in CF: it partially corrects F508del-CFTR trafficking, stimulates the bactericidal properties of CF alveolar macrophages, and displays anti-inflammatory properties and analgesic effects.Methods: A phase 2 trial study (ROSCO-CF) was launched to evaluate the safety and effects of roscovitine in Pseudomonas aeruginosa infected adult CF patients carrying two CF causing mutations (at least one F508del-CFTR mutation) and harboring a FEV1 ≥40%. ROSCO-CF was a multicenter, double-blind, placebo-controlled, dose-ranging study (200, 400, 800 mg roscovitine, orally administered daily for 4 days/week/4 weeks).Results: Among the 34 volunteers enrolled, randomization assigned 11/8/8/7 to receive the 0 (placebo)/ 200/400/800 mg roscovitine doses, respectively. In these subjects with polypharmacy, roscovitine was relatively safe and well-tolerated, with no significant adverse effects (AEs) other than five serious AEs (SAEs) possibly related to roscovitine. Pharmacokinetics of roscovitine were rather variable among subjects. No significant efficacy, at the levels of inflammation, infection, spirometry, sweat chloride, pain and quality of life, was detected in roscovitine-treated groups compared to the placebo-treated group.Conclusion: Roscovitine was relatively safe and well-tolerated in CF patients especially at the 200 and 400 mg doses. However, there were 5 subject withdrawals due to SAEs in the roscovitine group and none in the placebo group. The lack of evidence for efficacy of roscovitine (despite encouraging cellular and animal results) may be due to high pharmacokinetics variability, short duration of treatment, and/or inappropriate dosing protocol.

Abstract

ObjectivesLumacaftor-ivacaftor is a cystic fibrosis transmembrane conductance regulator (CFTR) modulator known to improve clinical status in people with cystic fibrosis (CF). This study aimed to assess lung structural changes after one year of lumacaftor-ivacaftor treatment, and to use unsupervised machine learning to identify morphological phenotypes of lung disease that are associated with response to lumacaftor-ivacaftor.MethodsAdolescents and adults with CF from the French multicenter real-world prospective observational study evaluating the first year of treatment with lumacaftor-ivacaftor were included if they had pretherapeutic and follow-up chest computed tomography (CT)-scans available. CT scans were visually scored using a modified Bhalla score. A k-mean clustering method was performed based on 120 radiomics features extracted from unenhanced pretherapeutic chest CT scans.ResultsA total of 283 patients were included. The Bhalla score significantly decreased after 1 year of lumacaftor-ivacaftor (−1.40±1.53 points compared with pretherapeutic CT; p1) ≥5 under lumacaftor–ivacaftor than those in the other clusters (54% of responders versus 32% and 33%; p=0.01).ConclusionOne year treatment with lumacaftor-ivacaftor was associated with a significant visual improvement of bronchial disease on chest CT. Radiomics features on pretherapeutic CT scan may help in predicting lung function response under lumacaftor-ivacaftor.

Abstract

Background Whereas Burkholderia infections are recognized to impair prognosis in cystic fibrosis (CF) patients, there is no recommendation to date for early eradication therapy. The aim of our study was to analyse the current management of initial colonisations with Burkholderia cepacia complex (BCC) or B. gladioli in French CF Centres and its impact on bacterial clearance and clinical outcome. Methods We performed a retrospective review of the primary colonisations (PC), defined as newly positive sputum cultures, observed between 2010 and 2018 in five CF Centres. Treatment regimens, microbiological and clinical data were collected. Results Seventeen patients (14 with BCC, and 3 with B. gladioli) were included. Eradication therapy, using heterogeneous combinations of intravenous, oral or nebulised antibiotics, was attempted in 11 patients. Six out of the 11 treated patients, and 4 out of the 6 untreated patients cleared the bacterium. Though not statistically significant, higher forced expiratory volume in 1 second and forced vital capacity at PC and consistency of treatment with in vitro antibiotic susceptibility tended to be associated with eradication. The management of PC was shown to be heterogeneous, thus impairing the statistical power of our study. Large prospective studies are needed to define whom to treat, when, and how. Conclusions Pending these studies, we propose, due to possible spontaneous clearance, to check the presence of Burkholderia 1 month after PC before starting antibiotics, at least in the milder cases, and to evaluate a combination of intravenous beta-lactam + oral or intravenous fluoroquinolone + inhaled aminoglycoside.

Abstract

International audience; Rationale: Lumacaftor-ivacaftor is a CFTR (cystic fibrosis transmembrane conductance regulator) modulator combination recently approved for patients with cystic fibrosis (CF) homozygous for the Phe508del mutation.Objectives: To evaluate the safety and effectiveness of lumacaftor-ivacaftor in adolescents (≥12 yr) and adults (≥18 yr) in a real-life postapproval setting.Methods: The study was conducted in the 47 CF reference centers in France. All patients who initiated lumacaftor-ivacaftor from January 1 to December 31, 2016, were eligible. Patients were evaluated for lumacaftor-ivacaftor safety and effectiveness over the first year of treatment following the French CF Learning Society's recommendations.Measurements and Main Results: Among the 845 patients (292 adolescents and 553 adults) who initiated lumacaftor-ivacaftor, 18.2% (154 patients) discontinued treatment, often owing to respiratory (48.1%, 74 patients) or nonrespiratory (27.9%, 43 patients) adverse events. In multivariable logistic regression, factors associated with increased rates of discontinuation included adult age group, percent predicted FEV1 (ppFEV1) less than 40%, and numbers of intravenous antibiotic courses during the year before lumacaftor-ivacaftor initiation. Patients with continuous exposure to lumacaftor-ivacaftor showed an absolute increase in ppFEV1 (+3.67%), an increase in body mass index (+0.73 kg/m2), and a decrease in intravenous antibiotic courses by 35%. Patients who discontinued treatment had significant decrease in ppFEV1, without improvement in body mass index or decrease in intravenous antibiotic courses.Conclusions: Lumacaftor-ivacaftor was associated with improvement in lung disease and nutritional status in patients who tolerated treatment. Adults who discontinued lumacaftor-ivacaftor, often owing to adverse events, were found at high risk of clinical deterioration.

Abstract

Allergic bronchopulmonary aspergillosis (ABPA) affects up to 15% of patients with cystic fibrosis (CF). Corticosteroids are used as first-line therapy, but relapse and adverse effects commonly occur. Case reports have suggested the efficacy of the anti-IgE recombinant humanized monoclonal antibody omalizumab. A retrospective multicenter observational French study retrieved 32 CF patients (11 children and 21 adults) who have received omalizumab for more than 3 months in the context of ABPA. Clinical characteristics, concomitant medications (inhaled and oral corticosteroids, antifungal drugs), lung function, body mass index (BMI), and serum IgE were compared at the start and during the first year of omalizumab therapy. Omalizumab-related adverse effects and costs were also evaluated. No significant difference with omalizumab could be demonstrated with regard to lung function, BMI, or the number of patients receiving oral corticosteroids. At the time of initiation of omalizumab, 56% of patients were receiving oral corticosteroids. Five patients were able to discontinue corticosteroids during follow-up and nine patients were able to reduce their daily dose. A total of 78% of the patients had received antifungal therapy at the time of the initiation of omalizumab. Treatment tolerance was good (12.5% of patients experienced side effects). The median cost of omalizumab treatment was €3,620 per patient per month. Omalizumab may represent a steroid-sparing therapy in CF patients with ABPA. A randomized-controlled trial is urgently required to provide higher level of evidence regarding the efficacy and cost-effectiveness of omalizumab in CF patients with ABPA.

Abstract

Pulmonary hypertension (PH) may affect survival in cystic fibrosis (CF) and can be assessed on echocardiographic measurement of the pulmonary acceleration time (PAT). The study aimed at evaluating PAT as a tool to optimize timing of lung transplant in CF patients. Prospective multicenter longitudinal study of patients with forced expiratory volume in 1 second (FEV1) ≤60% predicted. Echocardiography, spirometry and nocturnal oximetry were obtained as part of the routine evaluation. We included 67 patients (mean FEV1 42±12% predicted), among whom 8 underwent lung transplantation during the mean follow-up of 19±6 months. No patients died. PAT was determined in all patients and correlated negatively with systolic pulmonary artery pressure (sPAP, r=–0.36, P=0.01). Patients in the lowest PAT tertile (35 mmHg. By multivariate analysis, FEV1and nocturnal desaturation were the main determinants of reduced PAT. A PAT

Abstract

Objectives Pregnancy after lung transplantation remains rare. This French study deals with maternal and newborn outcomes and change in lung function after a pregnancy. Methods We retrospectively included 39 pregnancies in 35 lung transplant recipients over more than 20 years. Data about patients, course of pregnancies and newborns were collected from nine of the eleven French transplantation centers. Results Mean age at time of pregnancy was 28±5years. Cystic fibrosis affected 71% of our patients. Mean time between transplantation and pregnancy was 63±44 months. Twenty six births occurred (67%) with a mean term of 36±5 weeks gestation and a mean birth weight of 2409±921 g. Prematurity was observed in 11 cases (43%). Forced expiratory volume in one second was measured at 83.9% pred. before pregnancy and at 77.3% pred. 12 months later (p = 0.04). Ten patients developed chronic lung allograft dysfunction, 22.5±14.6 months after delivery. Up to now, nine patients died with a mean time after transplantation of 8.2±7 years and a mean time after pregnancy of 4.6±6.5 years. Conclusion Pregnancy in lung transplant recipients is possible. Maternal and newborn complications are more frequent than in general population. Survival in this cohort appears to be similar to global survival observed in lung transplant recipients. Planned pregnancy and multidisciplinary follow-up are crucial.

Abstract

Background Cetirizine and ebastine are two second-generation histamine H 1 antagonists undergoing evaluation for treatment of perennial rhinitis. Objective The clinical efficacy and safety of once daily cetirizine 10 mg were compared with ebastine 10 mg in patients with perennial allergic rhinitis in a 4-week, double-blind, parallel-group, randomized, multicenter study. Method Two hundred fourteen patients (120 females, 94 males, aged 17 to 70 years, mean 31.2 years) were selected on the basis of perennial allergic rhinitis history, positive skin test for perennial allergens and a minimum rhinitis symptom score of 6/12. Patients recorded nasal symptom severity (nasal stuffiness, nasal discharge, sneezing, and itching) once daily on diary cards using a rating scale of 0 (none) to 3 (severe). Clinicians made an overall evaluation after 4 weeks of treatment. An intent-to-treat-analysis was performed comparing cetirizine (106 patients) and ebastine groups (108 patients). Results The individual and total baseline symptom scores were comparable in both treatment groups. During the first week, the percentage mean decrease in the total nasal symptom score from baseline (sum of nasal stuffiness, discharge, sneezing, and itching) was significantly higher for cetirizine 46.2% than for ebastine 32.8% (P = .037). After 4 weeks of treatment, total symptom score improvement was 53.7% for cetirizine and 44.7% for ebastine (P = .12), and the clinician's overall evaluation showed that the percentage of symptom-free patients was significantly higher for cetirizine 17.8% than for ebastine 6.9% (P = .02). Cetirizine also significantly improved nasal stuffiness. An associated antiinflammatory effect is suggested. Commonly reported drug-related side effects were similar in both groups. Conclusion This study shows that both antihistamines, cetirizine 10 mg and ebastine 10 mg once a day, improved symptom scores of patients with perennial allergic rhinitis. Cetirizine, however, provided faster improvement and total relief in a greater number of patients after 4 weeks.
