RESUMO
BACKGROUND: Budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI), formulated using co-suspension delivery technology, is a triple fixed-dose combination in late-stage clinical development for chronic obstructive pulmonary disease (COPD). METHODS: We conducted two studies to characterize the pharmacokinetic (PK) profile of BGF MDI in patients with COPD: (i) a phase I, open-label, single and chronic (7-day) dosing study (NCT03250182) with one treatment arm (BGF MDI 320/18/9.6 µg); and (ii) a PK sub-study of KRONOS (NCT02497001), a phase III, randomized, double-blind study in which patients received 24 weeks' treatment with BGF MDI 320/18/9.6 µg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6 µg, budesonide/formoterol fumarate (BFF) MDI 320/9.6 µg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 320/9 µg. PK parameters in both studies included maximum observed plasma concentration (Cmax) and area under the plasma concentration-time curve from 0 to 12h (AUC0-12). RESULTS: In the phase I PK study (30 patients), budesonide and glycopyrronium Cmax were comparable after single and chronic dosing of BGF MDI (accumulation ratio [RAC] 95% and 107%, respectively) whereas Cmax for formoterol was slightly higher after chronic dosing (RAC 116%). AUC0-12 for budesonide, glycopyrronium, and formoterol were higher following chronic versus single dosing, with an RAC of 126%, 179%, and 143%, respectively. After 7 days' dosing, AUC0-12 and Cmax for all three components of BGF MDI were similar to those in the KRONOS PK sub-study (202 patients) at Week 24. In the latter sub-study, Cmax and AUC0-12 at Week 24 were generally comparable across treatments for budesonide (geometric mean ratios [GMR] of 96%-109% for BGF MDI vs BFF MDI or BUD/FORM DPI), glycopyrronium (GMR of 88%-100% for BGF MDI vs GFF MDI), and formoterol (GMR of 80%-113% for BGF MDI vs GFF MDI or BFF MDI). CONCLUSIONS: Steady-state PK parameters of budesonide, glycopyrronium, and formoterol were similar after 7 days' dosing in the phase I PK study and after 24 weeks in the KRONOS PK sub-study. Systemic exposure to budesonide, glycopyrronium, and formoterol was generally comparable across treatments in the KRONOS PK sub-study, suggesting no meaningful drug-drug or within-formulation PK interactions.

BACKGROUND: Aging is tightly linked to chronic disease, frailty, and death. Multi-morbidity, defined as the presence in the same patient of three or more conditions such as neoplastic, cardiovascular, neurodegenerative, metabolic, or autoimmune diseases, becomes more common with age. METHODS: The study was performed in a double-blind fashion. Subjects within each dose cohort (Cohorts 1, 2, 3, and 4) were randomly assigned to receive Isomyosamine doses (between 150 mg to 600 mg or placebo) or placebo in a 3:1 ratio (6 active: 2 placebo). RESULTS: Isomyosamine single daily doses each of 150 mg, 300 mg, and 450 mg for 3 days and multiple daily doses of 600 mg for 6 days were safe and well tolerated in healthy subjects. In one dose group, there was a decrease in TNF-α levels found in Isomyosamine treated subjects, but no change in the levels in subjects given placebo. The increase in Isomyosamine exposure was proportional to dose across the dose range of 300 mg to 600 mg when administered as a single dose. There was minimal accumulation of Isomyosamine following 5 days of once daily dosing of Isomyosamine 600 mg. Isomyosamine half-life ranged from approximately 15 minutes to 45 minutes across all doses in the single ascending dose and multiple ascending dose portion of the study. Elimination of Isomyosamine included the renal pathway as a minor route. CONCLUSION: Isomyosamine will continue to be investigated in phase 2 clinical trials for the treatment of sarcopenia/frailty, hashimoto's thyroiditis and rheumatoid arthritis.

Nebulized solutions of long-acting bronchodilators provide an alternative to DPI and MDI delivery, particularly for COPD patients unable to use hand-held devices easily or correctly. The long-acting beta2-agonist, formoterol fumarate, is differentiated by its onset of significant bronchodilation within 5 min of administration. In a randomized, double-blind, double-dummy trial, COPD subjects (n=351, mean forced expiratory volume FEV1=1.3 L, 44% predicted) received nebulized formoterol fumarate (Perforomist inhalation solution; FFIS 20 microg) or DPI (Foradil Aerolizer; FA 12 microg), or placebo twice daily for 12 weeks. Efficacy was assessed with 12-h pulmonary function tests, and quality of life was assessed before and after treatment with the St. George's Respiratory Questionnaire (SGRQ). At the 12-week endpoint, FFIS significantly increased FEV1 AUC0-12h relative to placebo (p<0.0001). No evidence of tachyphylaxis was observed as indicated by maintained FEV1 AUC and reduced rescue albuterol use throughout treatment. FFIS also significantly increased peak FEV1, trough FEV1, and standardized FVC AUC0-12h compared with placebo. SGRQ assessment at Week 12 demonstrated significant and clinically meaningful improvements in total score (FFIS vs placebo, -4.9, p=0.0067), symptom, and impact scores. No significant differences in efficacy were observed between the two active treatments. Drug related AEs in the FFIS arm with a frequency > or = 1% and exceeding placebo were dry mouth, nausea, and insomnia. Nebulized FFIS provided significant improvement in respiratory status and quality of life in subjects with COPD relative to placebo and was well tolerated. The efficacy and safety profile of FFIS was comparable to FA DPI.

BACKGROUND: Ipratropium bromide/albuterol Respimat inhaler (CVT-R) was developed as an environmentally friendly alternative to ipratropium bromide/albuterol metered-dose inhaler (CVT-MDI), which uses a chlorofluorocarbon propellant. OBJECTIVE: The objective of this study was to evaluate patient satisfaction, device usage, and long-term safety of CVT-R compared to CVT-MDI, and to the simultaneous administration of ipratropium bromide hydrofluoroalkane (HFA; I) and albuterol HFA (A) metered-dose inhalers as dual monotherapies (I + A). DESIGN: This is a 48-week, open-label, randomized, active-controlled, parallel-group study (n = 470) comparing CVT-R to CVT-MDI and to I + A. PARTICIPANTS: Patients were at least 40 years of age, diagnosed with chronic obstructive pulmonary disease (COPD), and current or exsmokers. INTERVENTIONS: Patients were randomized to receive: (1) CVT-R, one inhalation four times daily (QID); or (2) CVT-MDI, two inhalations QID; or (3) I + A two inhalations of each inhaler QID. MAIN MEASURES: Patient Satisfaction and Preference Questionnaire (PASAPQ) performance score (primary endpoint) and adverse events. KEY RESULTS: PASAPQ performance score was significantly higher (CVT-R versus CVT-MDI, 9.6; and CVT-R versus I + A, 6.2; both P < 0.001) when using CVT-R compared to CVT-MDI or I + A at all visits starting from week 3, while CVT-MDI and I + A treatment groups were similar. Time to first COPD exacerbation was slightly longer in the CVT-R group compared to the other treatment groups, although it did not reach statistical significance (CVT-R versus CVT-MDI, P = 0.57; CVT-R versus I + A, P = 0.22). Rates of withdrawal and patient refusal to continue treatment were lower in CVT-R compared with CVT-MDI and I + A groups (CVT-R versus CVT-MDI, P = 0.09; CVT-R versus I + A, P = 0.005). The percentage of patients reporting adverse events and serious adverse events was similar across all three treatment groups. CONCLUSION: CVT-R is an effective, environmentally friendly inhaler that provides patients with a high level of user satisfaction and may positively impact clinical outcomes while having no adverse impacts on patients using the device.
