The 24-h FEV1 time profile of olodaterol once daily via Respimat® and formoterol twice daily via Aerolizer® in patients with GOLD 2-4 COPD: results from two 6-week crossover studies.

ABSTRACT: ABSTRACT:These studies evaluated the 24-h forced expiratory volume in 1 sec (FEV1) profile of once-daily (QD) olodaterol compared to placebo and twice-daily (BID) formoterol in patients with moderate to very severe chronic obstructive pulmonary disease. In two replicate, randomized, double-blind, double-dummy, four-way crossover studies, patients received olodaterol 5 and 10 ?g QD, formoterol 12 ?g BID, or placebo for 6 weeks in addition to usual-care background maintenance therapy. Co-primary end points were FEV1 area under the curve from 0-12 h (AUC0-12) response (change from baseline) and FEV1 AUC from 12-24 h (AUC12-24) response after 6 weeks, with FEV1 AUC from 0-24 h response identified as a key secondary end point. Other secondary end points included FEV1 AUC from 0-3 h and trough FEV1 responses, as well as corresponding forced vital capacity responses. With both olodaterol doses, FEV1 increased to near-maximal 30 min post-morning dose, which was sustained over 24 h. FEV1 also increased within 30 min post-morning dose of formoterol and was sustained over 12 h; the second formoterol dose resulted in a further increase, sustained for an additional 12 h. FEV1 AUC0-12 and AUC12-24 responses with both QD olodaterol doses and BID formoterol were significantly greater than placebo at 6 weeks (P < .0001). Secondary end-point outcomes were consistent with those of the co-primary end points. These data, together with those from the wider phase III clinical program, provide evidence for the 24-h bronchodilator efficacy of olodaterol QD in this patient population.

Project description:Tiotropium + olodaterol has demonstrated improvements beyond lung function benefits in a large Phase III clinical program as a once-daily maintenance treatment for COPD and may be a potential option for the initiation of maintenance treatment in COPD. Despite guideline recommendations that combined long-acting ?2-agonists and inhaled corticosteroids should only be used in individuals at high risk of exacerbation, there is substantial use in individuals at lower risk. This raises the question of the comparative effectiveness of this combination as maintenance treatment in this group compared to other combination regimens.The study aimed to assess the effect on lung function of once-daily tiotropium + olodaterol versus twice-daily salmeterol + fluticasone propionate in all participants with Global initiative for chronic Obstructive Lung Disease 2 or 3 (moderate to severe) COPD.This was a randomized, double-blind, double-dummy, four-treatment, complete crossover study in which participants received once-daily tiotropium + olodaterol (5/5 µg and 2.5/5 µg) via Respimat(®) and twice-daily salmeterol + fluticasone propionate (50/500 µg and 50/250 µg) via Accuhaler(®) for 6 weeks. The primary end point was change in forced expiratory volume in 1 second (FEV1) area under the curve from 0 hour to 12 hours (AUC0-12) relative to the baseline after 6 weeks.Tiotropium + olodaterol 5/5 µg and 2.5/5 µg demonstrated statistically significant improvements in FEV1 AUC0-12 compared to salmeterol + fluticasone propionate (improvements from baseline were 317 mL and 295 mL with tiotropium + olodaterol 5/5 µg and 2.5/5 µg, and 188 mL and 192 mL with salmeterol + fluticasone propionate 50/500 µg and 50/250 µg, respectively). Tiotropium + olodaterol was superior to salmeterol + fluticasone propionate in lung function secondary end points, including FEV1 area under the curve from 0 hour to 24 hours (AUC0-24).Once-daily tiotropium + olodaterol in participants with moderate-to-severe COPD provided superior lung function improvements to twice-daily salmeterol + fluticasone propionate. Dual bronchodilation can be considered to optimize lung function in individuals requiring maintenance treatment for COPD.

Project description:BackgroundAntiretroviral therapy (ART) adherence is critical for successful HIV treatment outcomes. Once-daily dosing could improve adherence. Plasma concentrations of once-daily vs twice-daily abacavir + lamivudine are bioequivalent in children, but no randomized trial has compared virological outcomes.MethodsChildren taking abacavir + lamivudine-containing first-line regimens twice daily for more than 36 weeks in the ARROW trial (NCT02028676, ISRCTN24791884) were randomized to continue twice-daily vs move to once-daily abacavir + lamivudine (open-label). Co-primary outcomes were viral load suppression at week 48 (12% noninferiority margin, measured retrospectively) and lamivudine or abacavir-related grade 3/4 adverse events.ResultsSix hundred and sixty-nine children (median 5 years, range 1-16) were randomized to twice daily (n = 333) vs once daily (n = 336) after median 1.8 years on twice-daily abacavir + lamivudine-containing first-line ART. Children were followed for median 114 weeks. At week 48, 242/331 (73%) twice daily vs 236/330 (72%) once daily had viral load less than 80 copies/ml [difference -1.6% (95% confidence interval -8.4,+5.2%) P = 0.65]; 79% twice daily vs 78% once daily had viral load less than 400 copies/ml (P = 0.76) (week 96 results similar). One grade 3/4 adverse event was judged uncertainly related to abacavir + lamivudine (hepatitis; once daily). At week 48, 9% twice daily vs 10% once daily reported missing one or more ART pills in the last 4 weeks (P = 0.74) and 8 vs 8% at week 96 (P = 0.90). Carers strongly preferred once-daily dosing. There was no difference between randomized groups in postbaseline drug-resistance mutations or drug-susceptibility; WHO 3/4 events; ART-modifying, grade 3/4 or serious adverse events; CD4% or weight-for-age/height-for-age (all P > 0.15).ConclusionOnce-daily abacavir + lamivudine was noninferior to twice daily in viral load suppression, with similar resistance, adherence, clinical, immunological and safety outcomes. Abacavir + lamivudine provides the first once-daily nucleoside backbone across childhood that can be used to simplify ART.
