Anzueto 2009

Methods

Randomised, double‐blind parallel study. Duration: 52 weeks.

Participants

  1. Setting: 98 centre in USA and Canada. (study code SCO100250, clinicaltrials.gov# NCT00115492)

  2. Participants randomised: 797 (FPS: 394; salmeterol: 403)

  3. Baseline characteristics: Mean age: 65.4. Mean FEV1: 0.98L

  4. Inclusion criteria: aged ≥40 yrs. History ≥ 10 pack‐years, a pre‐albuterol FEV1/FVC ≤ 0.70, a

  5. FEV1 ≤ 50% of predicted normal and a documented history of at least 1 COPD exacerbation the year prior to the study that required treatment with antibiotics, oral corticosteroids, and/or hospitalisation.

  6. Exclusion criteria: current diagnosis of asthma, a respiratory disorder other than COPD, historical or current evidence of a clinically significant uncontrolled disease, or had a COPD exacerbation that was not resolved at screening

Interventions

Run‐in 4 weeks with open‐label fluticasone/salmeterol 250/50 Diskus BID. Following run‐in, subjects were randomised to FPS 250/50 or salmeterol twice‐daily via DISKUS for 52 weeks. Clinic visits were conducted at screening, day 1 (randomisation), and after 4, 8, 12, 20, 28, 36, 44, and 52 weeks. Treatments were assigned in blocks using a centre‐based randomisation schedule. Assignment to blinded study medication was stratified based on subjects' FEV1 response to albuterol at screen visit. Oral corticosteroids and antibiotics were allowed for the acute treatment of a COPD exacerbation.

Outcomes

The primary efficacy endpoint was the annual rate of moderate/severe exacerbations. Secondary endpoints were the time to first moderate/severe exacerbation, the annual rate of exacerbations requiring oral corticosteroids, and pre‐dose FEV1. Related endpoints included the annual rate of all exacerbations, time to onset of each moderate/severe exacerbation, and diary records of dyspnoea scores, nighttime awakenings due to COPD, and use of supplemental albuterol.

Notes

The run‐in with combined therapy precluded exacerbations due to ICS withdrawal.

Flow chart to illustrate separation of review between three comparisons. Six RCTs met the original entry criteria of the review. All of these had a placebo and long‐acting beta2‐agonist arm, and five assessed combination against steroids. Seven new studies with one or more control comparisons were identified: five had a placebo arm, three had a long‐acting beta2agonist arm, and two had an inhaled steroid treatment arm.

*The basis for the assumed risk (was the median control group risk across studies of one year duration). The corresponding risk (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI).
CI: Confidence interval; OR: Odds ratio;

GRADE Working Group grades of evidence
High quality: Further research is very unlikely to change our confidence in the estimate of effect.
Moderate quality: Further research is likely to have an important impact on our confidence in the estimate of effect and may change the estimate.
Low quality: Further research is very likely to have an important impact on our confidence in the estimate of effect and is likely to change the estimate.
Very low quality: We are very uncertain about the estimate.

1 This is the number of participants randomised in the studies. The analysis took account of the amount of time the participants were enrolled for prior to withdrawal.

2 Risk of bias (‐1): High withdrawal rates in all the longer trials.
3 Inconsistency (‐1): Significant heterogeneity between trial results.
4 Exacerbations were moderate or severe requiring oral corticosteroids, antibiotics or leading to hospital admission.

5 Publication bias (‐1): Data from a key study of fluticasone and salmeterol (TORCH) and from studies evaluating budesonide/formoterol were not available as binary data and did not contribute to this measurement of exacerbations. Whilst the analysis of the data as rates in these studies is likely to reflect the individual trial protocols, we cannot be sure that their absence from this outcome measure has little or no impact on the pooled odds ratio.

6 Annualised rates of hospitalisation have been estimated from the three year study TORCH.

7 Imprecision (‐1): Confidence interval includes possible harm and benefit.

8 See Table 2 for a range of NNT(H) results for risk of pneumonia across the trials of different durations.
