This section will summarize the preclinical and clinical studies for inhaled Pulmozyme® (recombinant human deoxyribonuclease, rhDNase), insulin, human growth hormone (hGH), cyclosporine, alpha-1 antitrypsin, measles vaccine, and anti-immunoglobulin E (IgE). For Pulmozyme® (rhDNase), monkeys had positive serum antibody titers to rhDNase and allergic/hypersensitivity (type I) lung lesions in response to foreign protein likely due to differences in homology between monkey and human DNases. However, in patients, the levels of rhDNase antibodies were low and of no consequence. For inhaled insulin in rats, dogs and monkeys, there were no adverse effects related to insulin or excipients. In clinical trials, over 13,000 patients were safely treated with inhaled insulin for an average of 1 year. Some patients had higher antibody levels than comparators, but these antibodies did not decrease the effectiveness, safety or tolerability of inhaled insulin over time and/or affect clinical outcomes. Inhaled hGH had no adverse effects in monkeys, healthy volunteers or pediatric patients, but its absorption from the lungs was too low (<5%) in pediatric patients to be successful as a medical product. Inhaled cyclosporine had no unexpected systemic toxicity or clinically limiting findings in the respiratory tract in rat and dogs; it also had promising Phase 2 clinical data but failed in Phase 3. Inhaled alpha-1 antitrypsin also failed in a recent Phase 2/3 trial. A liquid inhaled measles vaccine was safe, well tolerated and produced an appropriate immune response in Phase 2/3 studies for children ages 10-35 months, but not younger. A dry powder inhaled vaccine in monkeys had no adverse effects and produced an immune response; Phase 1 trials are underway. Inhaled anti-IgE was well tolerated in monkeys and asthma patients, but systemic delivery had superior results in patients.</p>","PeriodicalId":14940,"journal":{"name":"Journal of Aerosol Medicine and Pulmonary Drug Delivery","volume":"38 3","pages":"136-144"},"PeriodicalIF":2.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144187078","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The changes may include, but are not limited to, increase in batch size, alteration of the drug product constituent(s), improvement in the manufacturing process, and shift in manufacturing sites. The extent of pharmaceutical testing and the regulatory pathway for timely implementation of any change in the approved product and/or process depends upon the nature and extent of change. The U.S. Food and Drug Administration (FDA) has published guidelines that outline its expectations for the Scale-Up and Postapproval Changes (SUPAC) in the solid oral immediate and modified release (MR) products, and semisolid formulations. However, to date, no such guidelines have been issued to address SUPAC in the orally inhaled drug products (OIDPs), and this article represents a seminal contribution in this direction. It is hoped that it will inspire contributions from the relevant multidisciplinary experts from the pharmaceutical industry and the agency in accomplishing formal regulatory guidelines relevant to the OIDP SUPAC. The OIDPs are complex drug-device combination products. Therefore, a conceptualization of SUPAC guidelines for these products warrants consideration of contributions of effect of change(s) in individual components (drug substance, formulation, device) as well as a compound effect that a single or multiple changes may have on product performance, and its safety and efficacy. This article provides a discussion of scientific aspects and regulatory bases relevant to the development of SUPAC for OIDPs, and it attempts to outline considerations that may be applicable in addressing issues related to the OIDP SUPAC in the context of human drugs.

Regional therapy with cytotoxic agents has the potential to reduce the extent of systemic exposure to the drug and reduce the risk of systemic adverse effects. Regional chemotherapy has been successfully employed in the treatment of certain solid tumors such as hepatocellular carcinoma. However, regional chemotherapy has not been commonly utilized for treatment of lung tumors. Inhaled cytotoxic chemotherapy has the potential to become an effective regional therapy for both primary lung cancer and metastases to the lung from other primary tumors. Aerosol administration of chemotherapy could potentially avoid some of the adverse effects seen with systemic therapy. In addition, some chemotherapeutic agents when administered as an aerosol are absorbed directly into the arterial circulation and have therapeutic effects at extrapulmonary sites. Aerosol administration of several different chemotherapeutic agents is currently under evaluation either in the preclinical setting or in early phase human trials.

One of the primary reasons for their concerns stemmed from potential cardiovascular complications following epinephrine administration. However, the majority of documented cardiovascular complications seemed to occur following the injection route of the epinephrine. The aim of this study was to evaluate the systemic exposure of epinephrine delivered through different administration routes and to understand its relationship with cardiovascular effects. Since albuterol inhalers are commonly recommended for asthma, albuterol was also studied as a comparator drug. <b><i>Method:</i></b> A randomized, evaluator-blinded, three-arm crossover study was conducted in 28 healthy adult subjects to compare the profiles of systemic exposure for epinephrine delivered by MDI versus epinephrine intramuscular (IM) injection and albuterol MDI. Serially sampled plasma epinephrine and albuterol levels were measured and compared between treatment groups. Safety was assessed by adverse events, serial vital signs, electrocardiograms (ECGs), and clinical laboratory tests obtained at each crossover dosing visit. <b><i>Results:</i></b> Systemic exogenous drug exposure for inhaled epinephrine MDI (39 pg/mL × hour) was ∼9 times lower than that of epinephrine IM (435 pg/mL × hour) and 122 times lower than that of albuterol MDI (3453 pg/mL × hour) after dose normalization. The C<sub>max</sub> in epinephrine MDI (345 pg/mL) was approximately half of that of epinephrine IM (816 pg/mL) and that of albuterol MDI (681 pg/mL). Plasma drug concentrations for epinephrine MDI dropped rapidly to baseline (∼0.6 hour), while epinephrine IM took ∼8 hours, and albuterol MDI required more than 24 hours. Epinephrine MDI and albuterol MDI resulted in minimal, clinically insignificant changes in vital signs and ECGs, whereas epinephrine IM led to mild transient increases in systolic blood pressure, heart rate, and corrected QT interval. <b><i>Conclusion:</i></b> Epinephrine MDI (Primatene MIST) had ∼9 times lower systemic drug exposure (SDE) than that of epinephrine IM and ∼122 times lower than that of albuterol MDI.

Following the Montreal Protocol in 1987, the manufacture of a range of ozone-depleting substances, including CFCs, was gradually phased out, which required the propellants used in pMDIs to be replaced. Current pMDIs use hydrofluoroalkanes (HFAs) as propellants, such as 1,1,1,2-tetrafluoroethane (HFA-134a). Although these HFAs have no ozone-depleting potential, they have a high global warming potential (GWP), and consequently, their use is being phased down. One option for the discontinuation of HFA use in inhalers would be to discontinue all pMDIs, switching patients to dry powder inhalers (DPIs). However, a switch from pMDIs to DPIs may not be a clinically appropriate option for some patients; furthermore, the full lifecycle carbon footprint and the overall environmental impact of different inhalers should be considered. An alternative is therefore to reformulate the current HFA pMDIs to use low-GWP propellants, such as 1,1-difluoroethane (HFA-152a).
