Beclometasone dipropionate (BDP) is approved for the treatment of asthma in several countries via an HFA-134a propellant pMDI. This is being reformulated using the low global warming potential propellant HFA-152a. Two studies compared BDP pharmacokinetics delivered via pMDI using HFA-152a vs HFA-134a.</p><p><strong>Methods: </strong>Both studies (N=71/study) were single-dose (four inhalations of BDP), randomised, double-blind, crossover (Study 1, four-way; Study 2, two-way), in healthy volunteers. In Study 1, subjects inhaled BDP via HFA-134a pMDI in two periods (200 μg/actuation in one period, 100 μg/actuation in the other) and HFA-152a pMDI in the other two (200 or 100 μg/actuation). In Study 2, subjects inhaled BDP 200 μg/actuation via HFA-134a or HFA-152a pMDI using a spacer device. pMDIs containing HFA-152a and HFA-134a were compared in terms of lung availability (BDP comparisons) and total systemic exposure (beclometasone-17-monopropionate comparisons [B17MP; active metabolite of BDP]), with bioequivalence concluded if the 90% confidence intervals (CIs) of the geometric mean ratios of maximum plasma concentration (C_max) and area under the plasma concentration-time curve between time zero and the last quantifiable timepoint (AUC_0-t) were between 80-125%.</p><p><strong>Results: </strong>BDP C_max and AUC_0-t were equivalent for the two BDP 200 μg formulations, without (Study 1) and with spacer (Study 2). BDP 100 μg AUC_0-t met the bioequivalence criteria, but the C_max lower 90% CI was marginally below the bioequivalence limit (79.46%). B17MP C_max and AUC_0-t were bioequivalent with both propellants in all three comparisons.</p><p><strong>Conclusions: </strong>Overall, bioequivalence was confirmed of HFA-152a and HFA-134a for BDP 200 μg/actuation, with and without a spacer. Although bioequivalence of the two formulations cannot be formally concluded for BDP 100 μg, the minimal difference suggests the two formulations can be considered therapeutically equivalent.</p>","PeriodicalId":20799,"journal":{"name":"Pulmonary pharmacology & therapeutics","volume":" ","pages":"102356"},"PeriodicalIF":3.3,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143639799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subgroup analysis revealed an NNT of 3.0 for severe cases, underscoring the efficacy of ICS across different severity levels. Despite potential biases noted in some studies, sensitivity analyses confirmed the robustness of these findings. The GRADE assessment rated the quality of evidence as high.

Through analysis of radiation-induced lung injury datasets, intervention with ALDH2 agonists and inhibitors in an in vivo radiation-induced lung injury model, and establishment of an in vitro radiation-induced lung injury model using A549 stable cells with varying ALDH2 expressions, we discovered that ALDH2 expression is reduced in radiation-induced lung injury. Enrichment analysis suggested that ALDH2 may mitigate radiation-induced lung injury by modulating oxidative stress and inflammation levels. Additionally, single-cell data analysis reveals that ALDH2 is primarily localized in myeloid macrophages within the lungs, with its expression also being reduced in lung cancer patients. Subsequent examination of mouse pathological sections, reactive oxygen species (ROS), and inflammatory factor levels confirmed that ALDH2 can lessen radiation-induced lung injury by suppressing ROS and inflammatory factors. Both in vivo and in vitro Western blot analysis further validated that ALDH2 can attenuate epithelial-mesenchymal transition and inhibit the TGF-β1/Smad pathway.
