Efficacy and safety of once-daily QVA149 compared with the free combination of once-daily tiotropium plus twice-daily formoterol in patients with moderate-to-severe COPD (QUANTIFY): a randomised, non-inferiority study.

ABSTRACT:

Background

QVA149 is a once-daily (o.d.) inhaled dual bronchodilator containing a fixed-dose combination of the long-acting ?2-agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium for the treatment of COPD. The QUANTIFY study compared QVA149 with a free-dose bronchodilator combination of tiotropium plus formoterol (TIO+FOR) in improving health-related quality of life (HRQoL) of patients with COPD.

Methods

This multicentre, blinded, triple-dummy, parallel-group, non-inferiority study randomised patients aged ?40?years with moderate-to-severe COPD (post-bronchodilator forced expiratory volume in 1?s (FEV1) ?30% to <80% predicted) to QVA149 110/50?µg o.d. or TIO 18?µg o.d.+ FOR 12?µg twice daily (1:1) for 26?weeks. The primary endpoint was to demonstrate non-inferiority in HRQoL assessed using St George's Respiratory Questionnaire-COPD (SGRQ-C). The prespecified non-inferiority margin was 4 units. Secondary endpoints included Transition Dyspnoea Index (TDI) score, pre-dose FEV1, forced vital capacity (FVC) and safety.

Results

Of the 934 patients randomised (QVA149=476 and TIO+FOR=458), 87.9% completed the study. At week 26, non-inferiority was met for SGRQ-C (QVA149 vs TIO+FOR; difference: -0.69 units; 95% CI -2.31 to 0.92; p=0.399). A significantly higher percentage of patients achieved a clinically relevant ?1 point improvement in TDI total score with QVA149 (49.6%) versus TIO+FOR (42.4%; p=0.033). QVA149 significantly increased pre-dose FEV1 (+68?mL, 95% CI 37?mL to 100?mL; p<0.001) and FVC (+74?mL, 95% CI 24?mL to 125?mL; p=0.004) compared with TIO+FOR at week 26. The incidence of adverse events was comparable between both treatments (QVA149=43.7% and TIO+FOR=42.6%).

Conclusions

QVA149 is non-inferior to TIO+FOR in improving HRQoL, with clinically meaningful and significant improvements in breathlessness and lung function in patients with COPD.

Project description:BackgroundUmeclidinium bromide (UMEC) is an inhaled long-acting muscarinic antagonist in development for chronic obstructive pulmonary disease (COPD).MethodsThis was a multicentre, randomised, double-blind, placebo-controlled, three-way cross-over, incomplete block study to evaluate UMEC 15.6, 31.25, 62.5, and 125 μg administered once daily (QD), and UMEC 15.6 μg and 31.25 μg administered twice daily (BID), over 7 days in patients with COPD. Tiotropium was included as an open-label treatment arm. The primary efficacy endpoint was trough forced expiratory volume in 1 second (FEV1) on Day 8. Secondary efficacy endpoints included weighted mean FEV1 over 0-24 hours after morning dosing on Day 7, and serial FEV1 at each time point over 24 hours after morning dosing on Day 7. Safety and pharmacokinetics were also examined.ResultsOne hundred and sixty-three patients (mean age 59.5 years, 52% female) were randomised. Based on the population dose-response model of trough FEV1 data, the geometric mean potency (ED50) of UMEC was 37 μg (95% confidence interval [CI]: 18, 57) with a predicted maximum intrinsic efficacy (Emax) at trough of 0.185 L (95% CI: 0.153, 0.218) after QD dosing. UMEC 125 μg QD demonstrated the greatest improvements in measure of lung function compared with doses of 62.5 μg and below. UMEC 125 μg QD exhibited more consistent increases in FEV1 from baseline across serial time points over 24 hours compared with other UMEC doses and tiotropium. Increases in FEV1 over 0-12 hours were similar to those observed over 12-24 hours after the second dose of UMEC was administered. UMEC was rapidly absorbed following inhaled dosing and eliminated from plasma. Adverse events, generally mild, were highest with UMEC 125 μg QD (18%) compared with placebo (8%), tiotropium (4%) and other UMEC doses (5-12%).ConclusionsUMEC is a potent QD bronchodilator with geometric mean ED50 of 37 μg. A dose ordering over the range of UMEC 15.6-125 μg QD doses was observed, with UMEC 125 μg showing the greatest improvement in trough FEV1.

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.
