Long-term safety of once-daily indacaterol acetate/glycopyrronium bromide/mometasone furoate high-dose, and indacaterol acetate/mometasone furoate high-dose, in Japanese patients with inadequately controlled asthma: Results from two open-label, 52-week studies.

INTRODUCTION: The 52-week long-term safety of once-daily indacaterol acetate/glycopyrronium bromide/mometasone furoate (IND/GLY/MF) high-dose (150/50/160 µg) and IND/MF high-dose (150/320 µg) was evaluated in two studies enrolling Japanese patients with inadequately controlled asthma. METHODS: Study 1 (IND/GLY/MF) and Study 2 (IND/MF) were 52-week, phase III, open-label, single-arm, multicenter studies conducted in Japanese adult patients with inadequately controlled asthma. The primary endpoint was incidence and severity of treatment-emergent adverse events (AEs) over 52-weeks. RESULTS: In Study 1, 94 patients received IND/GLY/MF high-dose and 84 (89.4%) patients completed the 52-week study treatment; in Study 2, 51 patients received IND/MF high-dose and 48 (94.1%) patients completed the 52-week study treatment. In Study 1, 68.1% and 6.4% of 94 patients reported ≥1 AE and ≥1 serious AE (SAE) respectively. In Study 2, 78.4% of 51 patients reported ≥1 AE; no patients reported SAEs. The most commonly reported AEs were asthma (exacerbation; 30.9% and 54.9%) and nasopharyngitis (18.1% and 29.4%) in Study 1 and Study 2, respectively. Severe AEs including asthma (exacerbation) were reported in 13.8% and 13.7% of patients in Study 1 and Study 2, respectively. In Study 1, 10 patients (10.6%) reported treatment-related AEs, of which dysphonia (9 patients [9.6%]) was the most commonly reported; no treatment-related AEs were reported in Study 2. In Study 1, one death (not study drug-related) was reported after study discontinuation (92 days after last dose of study medication). CONCLUSIONS: Once-daily IND/GLY/MF and IND/MF high-dose were well-tolerated in Japanese patients with inadequately controlled asthma. No unexpected safety findings were observed.Supplemental data for this article is available online at.

Long-term safety and efficacy of donepezil in patients with dementia with Lewy bodies: results from a 52-week, open-label, multicenter extension study.

BACKGROUND/AIMS: To investigate the safety and efficacy of long-term administration (52 weeks) of donepezil in patients with dementia with Lewy bodies (DLB). METHODS: This was a 52-week, multicenter, open-label extension study. Up to 8 weeks after the completion of the preceding randomized, placebo-controlled trial (RCT), patients started treatment with 3 mg of donepezil daily for 2 weeks, followed by 5 mg daily for the remaining 50 weeks. Cognitive function, behavioral and psychiatric symptoms, cognitive fluctuations, and caregiver burden were assessed using the Mini-Mental State Examination, Neuropsychiatric Inventory, Cognitive Fluctuation Inventory, and the Zarit Caregiver Burden Interview, respectively. Safety parameters were monitored throughout. RESULTS: In total, 108 patients were enrolled in the study. Cognitive function and dementia-related behavioral symptoms, including cognitive fluctuations, were improved after the start of donepezil treatment, and improvement was maintained for 52 weeks. Reduction in caregiver burden observed in the preceding RCT returned to the baseline level at 52 weeks. There was no significant imbalance in the incidence of adverse events (AEs) by onset time, and delayed AE onset induced by the long-term administration of donepezil was unlikely to appear. CONCLUSION: The long-term administration of donepezil at 5 mg/day was well tolerated in patients with DLB and is expected to exhibit lasting effects, improving impaired cognitive function and psychiatric symptoms up to 52 weeks.

Donepezil for dementia with Lewy bodies: a randomized, placebo-controlled, confirmatory phase III trial.

INTRODUCTION: The efficacy of a cholinesterase inhibitor, donepezil, in patients with dementia with Lewy bodies (DLB) was investigated to confirm the superiority over placebo in the 12-week, double-blind phase of this phase III study. METHODS: Patients with probable DLB (n = 142) were randomly assigned to placebo or to 5 mg or 10 mg of donepezil administered once daily for 12 weeks. The co-primary endpoints were changes in cognitive function assessed using the Mini-Mental State Examination (MMSE) and behavioral and neuropsychiatric symptoms using the Neuropsychiatric Inventory (NPI-2: hallucinations and fluctuations). The superiority of each active group over placebo was determined with simultaneous statistical significance in both endpoints. Safety evaluations included adverse events (AEs) and the unified Parkinson's disease rating scale (UPDRS) part III. RESULTS: The predefined superiority of donepezil to the placebo was not confirmed in either active group in the primary analysis. MMSE score significantly improved compared to placebo in the 10 mg group (10 mg: 2.2 ± 0.4, placebo: 0.6 ± 0.5 (mean ± standard error); P = 0.016). The change in MMSE score in the 5 mg group was not significant (1.4 ± 0.5 (mean ± standard error); P = 0.232). Although NPI-2 improved compared to baseline in the active groups, the differences from placebo were not significant. Most AEs were mild or moderate. Although the incidence of parkinsonism was slightly higher in the 10 mg group, the change in the UPDRS score was minimal and without a significant difference from the placebo group. CONCLUSIONS: The co-primary endpoints were not achieved in this trial. However, significant improvement in MMSE score was demonstrated with 10 mg, but not 5 mg, of donepezil. The evaluation of psychiatric symptoms might be affected by advanced education and instructions given to caregivers. Overall, donepezil was well tolerated in patients with DLB. With careful attention on gastrointestinal or parkinsonian symptoms, patients with DLB can safely benefit from treatment with donepezil.

Long-term donepezil use for dementia with Lewy bodies: results from an open-label extension of Phase III trial.

INTRODUCTION: The long-term efficacy and safety of donepezil 10 mg in patients with dementia with Lewy bodies (DLB) were investigated in a 52-week Phase 3 trial. METHODS: This 52-week study consisted of 16-week randomized placebo-controlled (RCT) and 36-week open-label extension phases. Of 142 DLB patients enrolled in the RCT phase (three arms: placebo, 5 mg, and 10 mg), 110 entered the extension phase. The placebo group of the RCT phase initiated active treatment at week 16, and the active groups maintained allocated treatment and dosages until week 24. After week 24, all patients received 10 mg. Dose reduction to 5 mg for safety concerns was allowed. Efficacy measures included Mini-Mental State Examination (MMSE) for cognitive function and Neuropsychiatric Inventory (NPI) for behavioral symptoms. Safety evaluations included adverse events (AEs) and the unified Parkinson disease rating scale. RESULTS: In total, 100 subjects completed the study. Cognitive function improvement was sustained for 52 weeks (MMSE at week 52 in 10 mg: 2.8 ± 3.5 (mean ± standard deviation); P <0.001, Student paired t test)). Those who received placebo in the RCT phase showed an improvement after starting active treatment. NPI improved in all the groups throughout the study, including the placebo period. In the subgroup of the 5 mg group without remarkable cognitive or behavioral improvement at week 24, further improvement was observed after a dose increase to 10 mg. After week 24, 21 patients experienced dose reduction. The incidence of any AEs did not increase over time. CONCLUSIONS: The long-term administration of donepezil at 10 mg/day improved cognitive function for up to 52 weeks in patients with DLB without increasing the risk of clinically significant safety events.
