The Real-World Efficacy of Fixed Triple Inhalation Therapy in the Treatment of Moderate COPD Patients (RATIONALE Study).

Purpose: COPD affects more than 300 million people worldwide, requiring inhalation treatment. Novel triple formulations of ICS, LABAs and LAMAs are becoming the mainstay of treatment, however there is still a lack of clinical evidence for personalized therapy. Patients and Methods: RATIONALE was a non-interventional, prospective, 52 week study, assessing the effectiveness of beclometasone/formoterol/glycopyrronium-bromide (BDP/FF/G), in symptomatic COPD patients, with moderate airflow obstruction. The study included 4 visits, where data on demographic parameters, exacerbations, symptoms, quality of life (based on the EQ-5D-3L questionnaire) and lung function were collected. Data on adherence to treatment, based on prescriptions filled was collected from the database of the National Health Insurance Fund, with the patients' consent. The primary objective was the change of adherence to treatment during the study, compared to baseline. Results: Altogether 613 patients had been enrolled. Their average age was 64.56 years and 50.5% were female. The average CAT score was 20.86, and most patients had suffered minimum one exacerbation (82.2%). Average FEV1 was 59.6%. Most patients had some limitation in one or more dimensions of EQ-5D-3L, with an average visual analogue scale score (VAS) of 60.31. After 12 months of treatment, adherence improved significantly - proportion of patients in the highest adherence group increased from 29.8% to 69.7% (p<0.001). The average CAT score improved by 7.02 points (95% CI 5.82-8.21, p<0.001). There was a significant improvement in all dimensions of EQ-5D-3L, with an average increase of 17.91 (95% CI 16.51-19.31, p< 0.001) points in the VAS score. Exacerbation frequency also decreased significantly. Conclusion: Although limitations of observational studies are present, we observed that early introduction of fixed triple combination results in a marked improvement in adherence to treatment, symptom scores, exacerbation frequency and quality of life. The optimal choice of treatment is crucial for reaching the highest possible adherence.

Extrafine single inhaler triple therapy effectiveness in COPD patients previously treated with multiple-inhaler triple therapy: the TRIWIN study.

BACKGROUND: The extrafine single inhaler triple therapy (efSITT) containing beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 µg has proved to be efficacious in patients with chronic obstructive pulmonary disease (COPD) in randomized control trials. OBJECTIVE: TRIWIN study evaluated the effectiveness of efSITT delivering beclomethasone dipropionate/formoterol fumarate/glycopyrronium 87/5/9 µg in COPD patients previously treated with multiple-inhaler triple therapy (MITT) in a real-world study in Greece. DESIGN: Prospective, multicenter, observational, non-interventional study was conducted over 24 weeks. METHODS: A total of 475 eligible patients had moderate-to-severe COPD, an indication for treatment with efSITT, and were symptomatic despite receiving MITT. COPD Assessment Test (CAT) score, pulmonary function parameters, use of rescue medication, and adherence to inhaler use were recorded at baseline (Visit 1), 3 (Visit 2), and 6 months (Visit 3) after treatment. RESULTS: Mean CAT score decreased from 21.4 points at Visit 1, to 16.6 at Visit 2 and 15.1 at Visit 3 (p < 0.001 for all pair comparisons). At Visit 3, 79.8% of patients reached a CAT improvement exceeding minimal clinically important difference (⩾2), compared to baseline. Mean forced expiratory volume in 1 s (%pred.) increased from 55.4% at Visit 1 to 63.5% at the end of study period (p < 0.001), while mean forced vital capacity (%pred.) increased from 71.1% at Visit 1, to 76.7% at Visit 3 (p < 0.001). The mean Test of Adherence to Inhalers score increased from 42.5 to 45.3 and 46.3 points, for the three visits, respectively (p < 0.001 comparing Visits 1/2 and Visits 1/3; p = 0.006 comparing Visits 2/3). The percentage of patients showing good adherence rose from 33.7% at baseline to 58.3% at Visit 3. The percentage of patients using rescue medication during the last month dropped from 16.2% to 7.4% at the end of study period (p < 0.001). Pulmonary function parameters also improved. CONCLUSION: The TRIWIN results suggest that extrafine beclomethasone dipropionate/formoterol fumarate/glycopyrronium is effective in improving health status, pulmonary function, and adherence and in reducing rescue medication use in COPD patients previously treated with MITT, in a real-world setting in Greece.

Optimization of an in vitro method for assessing pulmonary permeability of inhaled drugs using alveolar epithelial cells.

INTRODUCTION: Inhalation of drugs for the treatment of pulmonary diseases has been used since a long time. Due to lungs' larger absorptive surface area, delivery of drugs to the lungs is the method of choice for different disorders. Here we present the establishment of a comprehensive permeability model using Type II alveolar epithelial cells and Beclomethasone Dipropionate (BDP) as a model drug delivered by pressurized metered dose inhaler (pMDI). METHODS: Using Type II alveolar epithelial cells, the method was standardized for parameters viz., cell density, viability, incubation period and membrane integrity. The delivery and deposition of drug were using the pMDI device with a Twin Stage Impinger (TSI) modified to accommodate cell culture insert having monolayer of cells. The analytical method for simultaneous estimation of BDP and Beclomathasone-17-Monopropionate (17-BMP) was validated as per the bioanalytical guidelines. The extent and rate of absorption of BDP was determined by quantifying the amount of drug permeated and the data represented by calculating its apparent permeability. RESULTS: Type II alveolar epithelial cells cultured at 0.55 × 105 cells/cm2 for 8-12 days under air-liquid interface were optimized for conducting permeability studies. The data obtained for absorptive transport showed a linear increase in the drug permeated against time for both BDP and 17-BMP along with proportional permeability profile. DISCUSSION: We have developed a robust in vitro model to study absorptive rate of drug transport across alveolar layer. Such models would create potential value during formulation development for comparative studies and selection of clinical candidates.

Beclomethasone loaded liposomes enriched with mucin: A suitable approach for the control of skin disorders.

Inflammatory skin disorders are the fourth leading cause of chronic non-fatal conditions, which have a serious impact on the patient quality of life. Due to their treatment with conventional corticosteroids, which often result in poor therapeutic efficacy, relapses and systemic side effects from prolonged therapy, these diseases represent a global burden that negatively impacts the global economy. To avoid these problems and optimize corticosteroid benefits, beclomethasone was loaded into liposome formulations specifically tailored for skin delivery. These formulations were enhanced with mucin (0.1 and 0.5 % w/v) to further ensure prolonged formulation permanence at the site of application. The addition of 0.5 % w/v mucin resulted in the formation of small unilamellar vesicles and multicompartment vesicles. Liposomes and 1mucin-liposomes were smaller (∼48 and ∼61 nm, respectively) and more monodispersed (PI ∼ 0.14 and ∼ 0.17, respectively) than 5mucin-liposomes, which were larger (∼137 nm), slightly polydispersed (PI ∼ 0.23), and less stable during storage (4 months in the dark at 25 °C). Liposomes were negatively charged (∼ -79 mV) irrespective of their composition, and capable of incorporating high amount of beclomethasone (∼ 80 %). In vitro studies on skin fibroblasts and keratinocytes confirmed the high biocompatibility of all formulations (viability ≥ 95 %). However, the use of mucin-liposomes resulted in higher efficacy against nitric oxide production and free radical damage. Finally, topical applications using 12-O-tetradecanoylphorbol-13-acetate-injured skin in vivo experiments showed that only the mucin-enriched formulations could restore healthy conditions within 4 days, underscoring promise as a treatment for skin disorders.

Efficacy and safety of different inhaled corticosteroids for bronchopulmonary dysplasia prevention in preterm infants: A systematic review and meta-analysis.

BACKGROUND: This systematic review and meta-analysis aimed to evaluate the efficacy and safety of inhaled corticosteroids (budesonide, beclomethasone, or fluticasone propionate) in preventing bronchopulmonary dysplasia (BPD) for premature infants. METHOD: Electronic databases, including PubMed, EMBASE, Web of science, Scopus, and Cochrane library, were searched from databases inception to January 2022 for eligible randomized controlled trials. Clinical outcomes such as BPD, mortality, BPD or death, adverse events, and neurodevelopmental outcomes were assessed. RESULTS: Overall, budesonide was significantly associated with a reduction in BPD at 36 weeks' postmenstrual age (RR 0.48; 95 % CI [0.38, 0.62]) and patent ductus arteriosus (PDA) (RR 0.75; 95 % CI [0.63, 0.89]) compared with control treatments. Early longer duration inhalation of budesonide alone was associated with a lower risk of BPD at 36 weeks' postmenstrual age and PDA compared with controls. Early shorter duration intratracheal instillation of budesonide with surfactant as vehicle was associated with a lower risk of BPD at 36 weeks' postmenstrual age and all-cause mortality compared with surfactant. There was no statistically significant difference between budesonide and control groups regarding neurodevelopmental impairment. Beclomethasone and fluticasone propionate did not show any superior or inferior effect on clinical outcomes compared to control treatments. CONCLUSION: These findings suggest that budesonide, especially intratracheal instillation of budesonide using surfactant as a vehicle, is a safe and effective option in preventing BPD for preterm infants. More well-design large-scale trials with long-term follow-ups are necessary to verify the present findings.

Anti-Inflammatory Potential of Beclometasone-Loaded Filomicelles on Activated Human Monocytes.

Polymeric micelles with a hydrophobic core represent versatile nanostructures for encapsulation and delivery of water-insoluble drugs. Here, water-insoluble beclometasone dipropionate (BDP) which is a potent anti-inflammatory therapeutic agent but limited to topical applications so far, is encapsulated. Therefore, this work used an amphiphilic block copolymer self-assembling into flexible polymeric filomicelles, which have recently proven to selectively target inflamed areas in patients with inflammatory bowel disease (IBD). The small diameter and flexibility of these filomicelles is considered beneficial for transepithelial passages, while their length minimizes the unspecific uptake into nontargeted cells. This work successfully establishes a protocol to load the water-insoluble BDP into the core of the filomicelles, while maintaining the particle stability to prevent any premature drug release. The anti-inflammatory efficacy of BDP-loaded filomicelles is further investigated on lipopolysaccharide (LPS) stimulated human monocytes. In these ex vivo assays, the BDP-loaded filomicelles significantly reduce TNF-α, IL-6, IL-1ß, IL-12p70, IL-17a, and IL-23 release after 24 h. Additional time course study of drug-loaded filomicelles and their comparison with a common water-soluble and unspecific corticosteroid demonstrate promising results with significant immune response suppression in stimulated monocytes after 2 and 6 h. These findings demonstrate the potential of polymeric filomicelles as a vehicle for potent water-insoluble corticosteroids.

Evaluating the pharmacokinetics of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide delivered via pressurised metered-dose inhaler using a low global warming potential propellant.

INTRODUCTION: Use of propellants with high global warming potential (such as HFA-134a) for pressurised metered-dose inhalers (pMDIs) is being phased down. Switching to dry-powder inhalers may not be clinically feasible for all patients; an alternative is reformulation using propellants with low global warming potential. The combination of beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide (BDP/FF/GB) is available for asthma or chronic obstructive pulmonary disease via pMDI using HFA-134a as propellant. This is being reformulated using the low global warming potential propellant HFA-152a. This manuscript reports three studies comparing BDP/FF/GB pharmacokinetics delivered via pMDI using HFA-152a vs HFA-134a. METHODS: The studies were four-way crossover, single-dose, randomised, double-blind, in healthy volunteers. In Studies 1 and 2, subjects inhaled four puffs of BDP/FF/GB (Study 1: 100/6/12.5 µg [medium-strength BDP]; Study 2: 200/6/12.5 µg [high-strength]), ingesting activated charcoal in two of the periods (once per propellant). In Study 3, subjects inhaled medium- and high-strength BDP/FF/GB using a spacer. All three studies compared HFA-152a vs HFA-134a in terms of lung availability and total systemic exposure of beclometasone-17-monopropionate (B17MP; active metabolite of BDP), BDP, formoterol and GB. Bioequivalence was concluded if the 90 % confidence intervals (CIs) of the ratios between formulations of the geometric mean maximum plasma concentration (Cmax) and area under the plasma concentration-time curve between time zero and the last quantifiable timepoint (AUC0-t) for the analytes were between 80 and 125 %. RESULTS: In Studies 1 and 2, systemic exposure bioequivalence (i.e., comparisons without charcoal block) was demonstrated, except for GB Cmax in Study 2 (upper 90 % CI 125.11 %). For lung availability (i.e., comparisons with charcoal block), B17MP and formoterol demonstrated bioequivalence in both studies, as did BDP in Study 2; in Study 1, BDP upper CIs were 126.96 % for Cmax and 127.34 % for AUC0-t). In Study 1, GB AUC0-t lower CI was 74.54 %; in Study 2 upper limits were 135.64 % for Cmax and 129.12 % for AUC0-t. In Study 3, the bioequivalence criteria were met for BDP, B17MP and formoterol with both BDP/FF/GB strengths, and were met for GB AUC0-t, although not for Cmax. Both formulations were similarly well tolerated in all three studies. CONCLUSIONS: Overall, while formal bioequivalence cannot be concluded for all analytes, these data suggest therapeutic equivalence of the new formulation with the existing BDP/FF/GB pMDI formulation, therefore supporting reformulation using a propellant with low global warming potential.

A systematic review of randomised controlled trials on topical nasal steroids.

Introduction: Intranasal corticosteroids (INCs) are the first line of therapy for chronic sinonasal conditions such as rhinitis and rhinosinusitis. Among these, one of the most frequently used is beclomethasone dipropionate (BDP). Over the years many studies have evaluated the efficacy of BDP as part of therapy for chronic rhinosinusitis (CRS) and allergic rhinitis (AR) along with nasal washes, which seems to be very well tolerated. Objective: To analyse the data in the literature regarding the various therapeutic regimens of BDP in different sinonasal disease and their efficacy and tolerability. Materials and methods: Using different search engines, the posology, efficacy, and tolerability of BDP were reviewed and a total of 64 full-length articles were examined for eligibility. After applying inclusion and exclusion criteria, 4 articles were reviewed. Results: BDP is among the group of INCs with significant improvement of nasal symptoms and has good efficacy and safety. Conclusions: BDP nasal spray is one of the most frequently prescribed INC for rhinitis and rhinosinusitis. Treatment with BDP resulted in significant and clinically meaningful improvements in nasal symptoms associated with AR and CRS. BDP is well tolerated, and the safety profile is similar to that of placebo in most patients. These results, in conjunction with the significant benefit reported in subjects with CRS and AR, provide convincing evidence of the overall effectiveness of BDP for the treatment of the full spectrum of sinonasal disease.

Characteristics of Users and New Initiators of Single- and Multiple-Inhaler Triple Therapy for Chronic Obstructive Pulmonary Disease in Germany.

Purpose: To assess patient characteristics of users and new initiators of triple therapy for chronic obstructive pulmonary disease (COPD) in Germany. Patients and Methods: Retrospective cohort study of patients with COPD and ≥1 prescription for single-inhaler triple therapy (SITT; fluticasone furoate/umeclidinium/vilanterol [FF/UMEC/VI] or beclomethasone dipropionate/glycopyrronium bromide/formoterol [BDP/GLY/FOR]) or multiple-inhaler triple therapy (MITT), using data from the AOK PLUS German sickness fund (1 January 2015-31 December 2019). The index date was the first date of prescription for FF/UMEC/VI or BDP/GLY/FOR (SITT users), or the first date of overlap of inhaled corticosteroid, long-acting ß2-agonist, and long-acting muscarinic antagonist (MITT users). Two cohorts were defined: the prevalent cohort included all identified triple therapy users; the incident cohort included patients newly initiating triple therapy for the first time (no prior use of MITT or SITT in the last 2 years). Patient characteristics and treatment patterns were assessed on the index date and during the 24-month pre-index period. Results: In total, 18,630 patients were identified as prevalent triple therapy users (MITT: 17,945; FF/UMEC/VI: 700; BDP/GLY/FOR: 908; non-mutually exclusive) and 2932 patients were identified as incident triple therapy initiators (MITT: 2246; FF/UMEC/VI: 311; BDP/GLY/FOR: 395; non-mutually exclusive). For both the prevalent and incident cohorts, more than two-thirds of patients experienced ≥1 moderate/severe exacerbation in the preceding 24 months; in both cohorts more BDP/GLY/FOR users experienced ≥1 moderate/severe exacerbation, compared with FF/UMEC/VI and MITT users. Overall, 97.9% of prevalent triple therapy users and 86.4% of incident triple therapy initiators received maintenance treatment in the 24-month pre-index period. Conclusion: In a real-world setting in Germany, triple therapy was most frequently used after maintenance therapy in patients with recent exacerbations, in line with current treatment recommendations.

Triple therapy (a combination of three different respiratory inhaled medications) is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience repeated short-term symptom flare-ups when taking dual therapy (a combination of two different respiratory medications). Previously, patients had to take triple therapy using two or three separate inhalers. More recently, single-inhaler triple therapies have been developed, meaning patients can take all three different medications at the same time via one single inhaler. This study assessed the characteristics of patients who were already receiving triple therapy, or who started triple therapy (either via multiple inhalers or a single inhaler), in Germany between January 2015 and December 2019. In total, 18,630 patients who were already receiving triple therapy during the study period, and 2932 patients who newly started using triple therapy were included. The study reported that more than two-thirds of included patients had experienced at least one flare-up of COPD symptoms in the 2 years before starting triple therapy. Most patients had also received another therapy for COPD before starting triple therapy. A small proportion of patients started taking triple therapy after receiving no other therapy for COPD in the previous 2 years. The results of the study suggest that triple therapy for COPD in Germany is most often used in accordance with recommendations (patients already receiving therapy and experiencing repeated symptom flare-ups).

Assessing Inhaled Corticosteroid Adherence and Responsiveness in Severe Asthma Using Beclometasone Dipropionate/Formoterol NEXThaler Dose-Counting and Nitric Oxide Monitoring.

BACKGROUND: Sixty-five percent of people with severe asthma and a fractional exhaled nitric oxide (Feno) greater than or equal to 45 parts per billion (ppb) are nonadherent to inhaled corticosteroids (ICSs). Digital devices recording both time of use and inhaler technique identify nonadherence and ICS responsiveness but are not widely available. As the NEXThaler dose counter activates only at an inspiratory flow rate of 35 L/min, this may provide an alternative to identifying ICS responsiveness. OBJECTIVE: To assess ICS adherence and responsiveness in severe asthma using beclometasone/formoterol (200/6 µg) NEXThaler (BFN) dose-counting. METHODS: Patients with severe asthma with a Feno greater than or equal to 45 ppb were invited to use BFN in place of their usual ICS/long-acting ß2-agonist. Feno, 6-item Asthma Control Questionnaire score, lung function, and blood eosinophil count were monitored for 3 months. A log10ΔFeno of greater than or equal to 0.24 was used to define Feno suppression as the primary marker of ICS responsiveness at day 28. RESULTS: Twenty-seven of 48 (56%) patients demonstrated significant Feno suppression at month 1 (median pre-114, post-48 ppb, P < .001). A small but significant reduction occurred in Feno nonsuppressors. The 6-item Asthma Control Questionnaire score fell a median 1.2 units in Feno suppressors (P < .001) and 0.5 units in nonsuppressors (P = .025). These effects were sustained until month 3 in Feno suppressors, with a significant improvement in FEV1 and blood eosinophils. Sixty-seven percent (18 of 27) of those with baseline ICS/long-acting ß2-agonist prescription refills of 80% or more were Feno suppressors, suggesting prior nonadherence despite adequate prescription collection. Seventy-nine percent of Feno suppressors did not require biologics within mean 11.4 months from initial dose counting. CONCLUSIONS: BFN dose-counting identifies ICS responsiveness in severe asthma with the implication that these patients may not need to progress to biological therapies.

TRITRIAL: The Impact of Fixed Triple Therapy with Beclometasone/Formoterol/Glycopyrronium on Health Status and Adherence in Chronic Obstructive Pulmonary Disease in an Italian Context of Real Life.

Purpose: The TRITRIAL study assessed the effects of beclometasone dipropionate/formoterol fumarate/glycopyrronium (BDP/FF/G) fixed combination in patients with chronic obstructive pulmonary disease (COPD) in a real-world setting, focusing on patient's experience and perspective through the use of patients reported outcomes. Patients and Methods: TRITRIAL was a multicenter, prospective, observational study conducted on patients with moderate-severe COPD treated with BDP/FF/G fixed therapy for 12 months. The main objective was to evaluate the impact of BDP/FF/G on health status through the COPD Assessment Test (CAT) score. Additional assessments included adherence and satisfaction, measured by the TAI-10/12 questionnaire and a specifically designed eight-item questionnaire, quality of life through the EQ-5D-5L test, sleep quality through the COPD and Asthma Sleep Impact Scale (CASIS), as well as safety and disease-related outcomes. Results: Data from 655 patients were analyzed in the study. The mean total CAT score significantly improved (from 22.8 at baseline to 18.1 at 6 months and 16.5 at 12 months; p < 0.0001), as well as all the eight CAT sub-items, which decreased on average by 0.5-0.9 points during the study. Adherence and usability of the inhaler also improved during the study, with a decrease in poor compliance (from 30.1% to 18.3%) and an increase in good compliance (from 51.8% to 58.3%) according to the TAI score. Patients also benefited from significantly improved quality of life (EQ Index from 0.70 to 0.80; EQ-5D VAS score from 55.1 to 63.1) and sleep quality (CASIS score from 41.1 to 31.8). Finally, patients reported a significant reduction in exacerbation during the study. Conclusion: TRITRIAL showed that the BDP/FF/G fixed combination is effective and safe in patients with moderate-severe COPD and poorly controlled disease, improving patients' HRQoL, sleep quality, adherence and inhaler usability and reducing COPD symptoms and the risk of exacerbation in a real-life setting.

Which intranasal corticosteroids can be used in patients on highly active antiretroviral therapy or pre-exposure prophylactic?

KEY POINTS: All intranasal corticosteroid spray formulations are safe to use in patients on pre-exposure prophylaxis. Beclomethasone nasal spray can be used safely with all HAART and PrEP regimens.

Prescribing practices of inhaled corticosteroids for premature infants in the neonatal intensive care unit.

OBJECTIVE: Despite limited safety and efficacy data, inhaled corticosteroids (ICS) are prescribed to premature infants in the neonatal intensive care unit (NICU). We examined contemporary use and risk factors for ICS use in the NICU. STUDY DESIGN: Infants <33 weeks gestational age and <1500 gm birth weight discharged from Pediatrix Medical Group NICUs between 2010 and 2020 were included. We evaluated the association between ICS prescription and clinical characteristics using univariable and multivariable logistic regression. RESULTS: Of 74,123 infants from 308 NICUs, 9253 (12.5%) were prescribed ICS: budesonide, fluticasone, or beclomethasone. Diagnosis of bronchopulmonary dysplasia (BPD), earlier gestational age, male sex, longer mechanical ventilation, oxygen support, and systemic steroids were independent risk factors for ICS prescription. CONCLUSIONS: Use of ICS is common in many NICUs and is associated with a diagnosis of BPD and healthcare utilization. Prospective trials are needed to establish the safety, efficacy, and optimal indication in this vulnerable population.

Service readiness for the management of non-communicable diseases in publicly financed facilities in Malawi: findings from the 2019 Harmonised Health Facility Assessment census survey.

INTRODUCTION: Non-communicable diseases (NCDs) are rising in low-income and middle-income countries, including Malawi. To inform policy-makers and planners on the preparedness of the Malawian healthcare system to respond to NCDs, we estimated NCD service readiness in publicly financed healthcare facilities in Malawi. METHODS: We analysed data from 564 facilities surveyed in the 2019 Harmonised Health Facility Assessment, including 512 primary healthcare (PHC) and 52 secondary and tertiary care (STC) facilities. To characterise service readiness, applying the law of minimum, we estimated the percentage of facilities with functional equipment and unexpired medicines required to provide NCD services. Further, we estimated permanently unavailable items to identify service readiness bottlenecks. RESULTS: Fewer than 40% of PHC facilities were ready to deliver services for each of the 14 NCDs analysed. Insulin and beclomethasone inhalers had the lowest stock levels at PHC facilities (6% and 8%, respectively). Only 17% of rural and community hospitals (RCHs) have liver and kidney diagnostics. STC facilities had varying service readiness, ranging from 27% for managing acute diabetes complications to 94% for chronic type 2 diabetes management. Only 38% of STC facilities were ready to manage chronic heart failure. Oral pain medicines were widely available at all levels of health facilities; however, only 22% of RCHs and 29% of STCs had injectable morphine or pethidine. Beclomethasone was never available at 74% of PHC and 29% of STC facilities. CONCLUSION: Publicly financed facilities in Malawi are generally unprepared to provide NCD services, especially at the PHC level. Targeted investments in PHC can substantially improve service readiness for chronic NCD conditions in local communities and enable STC to respond to acute NCD complications and more complex NCD cases.

Divergent Chemo- and Biocatalytic Route to 16ß-Methylcorticoids: Asymmetric Synthesis of Betamethasone Dipropionate, Clobetasol Propionate, and Beclomethasone Dipropionate.

16ß-Methylcorticoids are among the most important glucocorticoid steroids for the treatment of various dermatological disorders, respiratory infections, and other allergic reactions elicited during inflammatory responses of the human body. Betamethasone dipropionate, clobetasol propionate, and beclomethasone dipropionate are particularly noteworthy for their synthetic intractability. Despite five decades of research, these 16ß-methylcorticoids have remained challenging synthetic targets owing to insurmountable issues of reactivity, selectivity, and cost efficiency associated with all previously explored strategies. We herein report our practicability-oriented strategy toward the unified stereoselective synthesis of 16ß-methylcorticoids in 12.6-14.0 % overall yield from commercially available 9α-hydroxyandrost-4-ene-3,17-dione (9α-OH-AD). In this approach, the chiral C16ß-Me and C17α-OH groups of the corticosteroid D ring were installed via a substrate-controlled diastereo- and enantioselective Mn-catalyzed oxidation-reduction hydration of Δ4,9(11),16 -triene-3,20-dione. The C1-C2 double bond of the corticosteroid A ring was constructed using an unprecedented engineered 3-ketosteroid-Δ1 -dehydrogenase (MK4-KstD)-catalyzed regioselective Δ1 -dehydrogenation of Δ4,9(11) -diene-3,21-dione. This strategy provides a general method and a key precursor for the divergent synthesis of a variety of glucocorticoids and related steroidal drugs.

Improvement of asthma control in adult patients using extrafine inhaled beclomethasone/formoterol fixed combination as maintenance therapy as well as maintenance and reliever therapy - CONTROL study.

INTRODUCTION: Extrafine formulation of beclomethasone/formoterol fixed combination (BDP/F pMDI HFA) is approved for both fixed maintenance and maintenance and reliever therapy (MART) of asthma, and recent data has proven that BDP/F pMDI HFA maintenance and reliever therapy is an effective alternative to other regimens. OBJECTIVE: This study aimed to assess the level of asthma control in a real-life setting in adult patients using extrafine BDP/F pMDI HFA fixed combination in a pressurized metered-dose inhaler (pMDI) as fixed maintenance dosing as well as maintenance and maintenance and reliever therapy. Additionally, we examined patients' satisfaction with the inhaler device and compliance with therapy as essential factors determining asthma control. METHODS: This multicenter prospective non-interventional observational study lasted 4 months with 3 patient visits. We used the Asthma Control Questionnaire 7 (ACQ-7) to evaluate the degree of asthma control and Morisky Medication Adherence Scale (MMAS-4) to assess compliance. A self-developed questionnaire was used to assess satisfaction with the inhaler device. RESULTS: 2179 patients using BDP/F pMDI HFA fixed combination as maintenance and reliever therapy or BDP/F pMDI HFA as maintenance therapy and SABA (short-acting beta2-agonist) as a reliever for at least 2 months were included. During the prospective follow-up, we observed an upward trend in the FEV1% (forced expiratory volume in 1 s) predicted values, improvement in the control of symptoms as indicated by a decline in the mean ACQ-7 score was noted (1.62 at Visit 1 vs. 1.21 at Visit 2 vs. 0.94 at Visit 3, p < 0.001) and increase in patients' compliance (the number of patients that reported forgetting at times to take their medication was reduced from 49.7 % to 27.1 %, p < 0.001). At the same time, we noted a reduction in the number of as-needed doses used for symptom relief (p < 0.001). Most patients were satisfied with the pMDI, considered it easy and convenient to use, and preferred it to a dry powder inhaler (p < 0.001). CONCLUSIONS: The use of extrafine BDP/F pMDI HFA as maintenance as well as reliever therapy seems to be associated with increased asthma control and better compliance to therapy.

Comparison of extrafine beclomethasone dipropionate/formoterol fumarate dry powder inhaler and pressurized metered-dose inhaler in Chinese patients with asthma: the FORTUNE study.

OBJECTIVE: When selecting inhaled therapies, it is important to consider both the active molecules and the device. Extrafine formulation beclomethasone dipropionate plus formoterol fumarate (BDP/FF) has been available for some years delivered via pressurized metered-dose inhaler (pMDI). More recently, a breath-activated, multi-dose dry-powder inhaler (DPI), the NEXThaler, has been approved. The current study aimed to demonstrate the non-inferiority of BDP/FF delivered via the DPI vs. via the pMDI, in Chinese adults with asthma. METHODS: After a four-week run-in period, when all patients received BDP/FF pMDI 100/6 µg, two inhalations twice daily (BID), patients were randomized equally to BDP/FF pMDI or DPI, both 100/6 µg, two inhalations BID for 12 weeks. The primary objective was to demonstrate non-inferiority of BDP/FF DPI vs. BDP/FF pMDI in terms of average pre-dose morning peak expiratory flow (PEF) over the entire treatment period. RESULTS: Of 252 and 242 patients in the DPI and pMDI groups, respectively, 88.5% and 88.8% completed the study. The primary objective was met, with no statistically significant difference between the treatments in average pre-dose morning PEF, and with the lower limit of the 95% CI above the -15 L/min non-inferiority margin (adjusted mean difference: 5.25 L/min [95% CI: -0.56, 11.06]). Adverse events were reported by 48.4% and 49.6% patients in the DPI and pMDI groups, respectively, most mild or moderate. CONCLUSIONS: The NEXThaler DPI is a similarly effective device to the pMDI for the administration of BDP/FF in adults, so extending the options available for the management of asthma.

Inhaled beclomethasone in the treatment of early COVID-19: a double-blind, placebo-controlled, randomised, hospital-based trial in Sri Lanka.

OBJECTIVES: To study if early initiation of inhaled beclomethasone 1200 mcg in patients with asymptomatic, mild or moderate COVID-19 reduces disease progression to severe COVID-19. DESIGN: Double-blinded, parallel-groups, randomised, placebo-controlled trial. SETTING: A hospital-based study in Sri Lanka. PARTICIPANTS: Adults with asymptomatic, mild or moderate COVID-19, presenting within the first 7 days of symptom onset or laboratory diagnosis of COVID-19, admitted to a COVID-19 intermediate treatment centre in Sri Lanka between July and November 2021. INTERVENTIONS: All participants received inhaled beclomethasone 600 mcg or placebo two times per day, for 10 days from onset of symptoms/COVID-19 test becoming positive if asymptomatic or until reaching primary endpoint, whichever is earlier. PRIMARY OUTCOME MEASURE: Progression of asymptomatic, mild or moderate COVID-19 to severe COVID-19. SECONDARY OUTCOME MEASURES: The number of days with a temperature of 38°C or more and the time to self-reported clinical recovery. RESULTS: A total of 385 participants were randomised to receive beclomethasone(n=193) or placebo(n=192) stratified by age (≤60 or >60 years) and sex. One participant from each arm withdrew from the study. All participants were included in final analysis. Primary outcome occurred in 24 participants in the beclomethasone group and 26 participants in the placebo group (RR 0.90 ; p=0.763). The median time for self-reported clinical recovery in all participants was 5 days (95% CI 3 to 7) in the beclomethasone group and 5 days (95% CI 3 to 8) in the placebo group (p=0.5). The median time for self-reported clinical recovery in patients with moderate COVID-19 was 5 days (95% CI 3 to 7) in the beclomethasone group and 6 days (95% CI 4 to 9) in the placebo group (p=0.05). There were no adverse events. CONCLUSIONS: Early initiation of inhaled beclomethasone in patients with asymptomatic, mild or moderate COVID-19 did not reduce disease progression to severe COVID-19.

Can single-inhaler Beclometasone Dipropionate/Formoterol Fumarate/Glycopyrronium therapy postpone or save biologics for severe asthma?

Inhaled corticosteroids, along with beta2-agonists and anti-muscarinics, represent the cornerstone of asthma treatment. Although the advent of monoclonal antibodies has dramatically changed severe asthma management, there are still patients ineligible or with poor response to biologics. Moreover, high costs associated with monoclonal antibodies prescription are still an open issue, leading clinicians to carefully assess cost-benefit ratio before their administration. From this perspective, the use of single-inhaler Beclometasone Dipropionate/Formoterol Fumarate/Glycopyrronium in patients with severe asthma could not only improve their clinical and functional performance, but also postpone biologic prescription, with positive repercussions on healthcare costs.

The effect of inhaled extrafine beclometasone dipropionate/formoterol fumarate/glycopyrronium bromide on distal and central airway indices, assessed using Functional Respiratory Imaging in COPD (DARWiIN).

BACKGROUND: This study, in patients with symptomatic chronic obstructive pulmonary disease (COPD), explored switching therapy from non-extrafine high-dose inhaled corticosteroid/long-acting ß2-agonist (ICS/LABA; fluticasone propionate/salmeterol [FP/SLM]) to extrafine medium-dose beclometasone dipropionate/formoterol fumarate dihydrate/glycopyrronium (BDP/FF/G), both via dry-powder inhaler. Functional Respiratory Imaging, a quantitative computed tomography method with 3D reconstructions of pulmonary anatomy, was used to assess airway geometry and lung function. METHODS: Patients receiving a stable ICS/LABA regimen for ≥ 8 weeks were switched to FP/SLM 500/50 µg, one inhalation twice-daily (high-dose ICS) for 6 weeks. After baseline assessments (Visit 2 [V2]), therapy was switched to BDP/FF/G 100/6/10 µg, two inhalations twice-daily (medium-dose ICS) for 6 weeks, followed by V3. The primary endpoints were percentage changes in specific image-based airway volume (siVaw) and resistance (siRaw) from baseline to predose at V3 (i.e., chronic effects), assessed at total lung capacity (TLC) in central and distal lung regions. Secondary endpoints included siVaw and siRaw changes from pre-dose to post-dose at V2, and from pre-dose to post-dose at V3 at TLC (i.e., acute effects), and chronic and acute changes in siVaw and siRaw at functional residual capacity (FRC). Pre-dose forced expiratory volume in 1 s (FEV1) and COPD Assessment Test (CAT) were also assessed. RESULTS: There were no significant changes in pre-dose siVaw or siRaw at TLC from baseline to V3, although at FRC there was a significant decrease in mean siRaw in the distal airways (- 63.6%; p = 0.0261). In addition, in the distal airways there were significant acute effects at TLC on mean siVaw and siRaw (siVaw: 39.8% and 62.6%; siRaw: - 51.1% and - 57.2%, V2 and V3, respectively; all p < 0.001) and at FRC at V2 (siVaw: 77.9%; siRaw: - 67.0%; both p < 0.001). At V3, the mean change in pre-dose FEV1 was 62.2 mL (p = 0.0690), and in CAT total score was - 3.30 (p < 0.0001). CONCLUSIONS: In patients with symptomatic COPD receiving high-dose ICS/LABA, adding a long-acting muscarinic antagonist while decreasing the ICS dose by switching to medium-dose extrafine BDP/FF/G was associated with improved airway indices, especially in the distal airways, together with improvements in respiratory health status.
