LTRA+LABA compared with ICS+LABA Summary of findings We found one fair quality RCT comparing LTRA plus LABA with ICS plus LABA (Appendix 243 H, Table H-16 and Table 24). The fair-rated, placebo-controlled, multi-center RCT (N = 192) compared ML (10mg/day) plus SM (100 mcg/day) plus placebo ICS (N = 98) compared with low dose BDP (160 mcg/day) plus SM (100 mcg/day) plus placebo LTRA (N = 92) for 14 243 weeks, washout for 4 weeks, then crossover for another 14 weeks. Subjects age 12 to 65 with moderate asthma were enrolled from multiple sites in the United States. There was a 4-week run- in period that involved a single-blind treatment with both BDP (160 mcg/day) and ML (10 mg/day). The primary objective of the study was to assess time until treatment failure. The trial was terminated early because the Data and Safety Monitoring Board determined that the primary research question had been answered. Those treated with LTRA+LABA had significantly shorter time to treatment failure than those treated with ICS+LABA (P = 0.

Controller medications for asthma 144 of 369 Final Update 1 Report Drug Effectiveness Review Project Key Question 2. Adverse Events What is the comparative tolerability and frequency of adverse events for controller medications used to treat outpatients with persistent asthma? Inhaled Corticosteroids Summary of Findings 22, 23, 244-248 27-33, 35-50, 52-55, 58-70, 249-258 We found seven systematic reviews, 50 RCTs and 12 259-269 observational studies reporting the tolerability or frequency of adverse events for inhaled corticosteroids meeting our inclusion/exclusion criteria (Table 7 and Evidence Tables A and B). Few RCTs were designed to assess adverse events as primary outcomes; most published studies designed to assess adverse events were observational studies. The overall incidence of adverse events and withdrawals due to adverse events are similar for equipotent doses of ICSs; results from head-to-head RCTs suggest no significant differences between ICSs (moderate strength of evidence). Overall summaries for specific adverse events are described below in the specific adverse events section. Most of the data for specific adverse events comes from placebo-controlled trials or observational studies, rather than from head-to-head comparisons. Detailed Assessment Description of Studies Most studies that examined the efficacy of one ICS relative to another (described in Key Question 1) also reported tolerability and adverse events. Six head-to-head RCTs that did not 249-252, 257, 258 report efficacy met our inclusion/exclusion criteria for tolerability or adverse events. Placebo-controlled RCTs and observational studies are described below in their respective specific adverse event sections. Methods of adverse events assessment differed greatly. Few studies used objective scales such as the adverse reaction terminology from the World Health Organization (WHO). Most studies combined patient-reported adverse events with a regular clinical examination by an investigator. Often it was hard to determine if assessment methods were unbiased and adequate; many trials reported only those adverse events considered to be related to treatment. Rarely were adverse events prespecified and defined. Short study durations and small sample sizes limited the validity of adverse events assessment in many trials. Many studies excluded eligible participants that did not tolerate treatment during the run-in period, limiting the generalizability of adverse event assessment. Few RCTs were designed to assess adverse events as primary outcomes; some studies were post hoc analyses or retrospective reviews of databases. Overall adverse events, tolerability, and common adverse events Of the 47 head-to-head studies reviewed for this section, most reported frequency of adverse events without tests of statistical significance (Appendix I).

Targeted immune modulators 106 of 195 Final Update 3 Report Drug Effectiveness Review Project SUMMARY Our conclusions are based on the review of 5210 abstracts and the inclusion of 163 studies. The large majority of these studies were funded by the pharmaceutical industry and could be classified as efficacy trials with highly selected patients. Few studies existed that enrolled less selected, primary care based populations. Overall, however, results between efficacy trials and more generalizable effectiveness studies appear to be consistent with only small variations in the magnitude of effects (see Table 21). In summary, insufficient evidence exists for most comparisons about the efficacy, effectiveness, and safety of abatacept, adalimumab, alefacept, anakinra, certolizumab pegol, etanercept, golimumab, infliximab, natalizumab, rituximab, tocilizumab, and ustekinumab for the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, ankylosing spondylitis, psoriatic arthritis, Crohn’s disease, ulcerative colitis, and plaque psoriasis. The most obvious differences that might be clinically decisive for choosing a targeted immune modulator involve dosage and administration. Infliximab, natalizumab, rituximab, and tocilizumab require intravenous administration. Abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, golimumab, and ustekinumab can be administered subcutaneously. Furthermore, administration intervals differ substantially: adalimumab requires an injection once every other week, anakinra has to be administered daily, etanercept once a week, certolizumab pegol every other week, tocilizumab every 4 weeks, golimumab monthly, and ustekinumab every 4 to 12 weeks. Comparative Effectiveness Rheumatoid Arthritis One fair-quality, double-blinded head-to head trial provided evidence of moderate strength that abatacept and infliximab do not differ in efficacy for the treatment of rheumatoid arthritis up to 6 months. The safety profile, however, appeared to be better for abatacept than for infliximab with fewer serious adverse events (9. Other direct comparisons of targeted immune modulators for the treatment of rheumatoid arthritis are limited to one small randomized controlled trial and multiple observational studies rendering evidence of low strength. These studies indicated no differences in efficacy and safety between adalimumab and etanercept but greater response rates for adalimumab and etanercept compared with infliximab. No differences in safety were obvious in these studies. All of the observational studies were population-based and had high applicability. None of these studies provided any evidence on radiographic outcomes. Adjusted indirect comparisons suggested greater efficacy for etanercept than abatacept, adalimumab, anakinra, and infliximab for the treatment of rheumatoid arthritis. One landmark 53,54 trial was excluded from our analyses because of heterogeneity of population. If this trial is included in the indirect comparisons no statistical advantage for etanercept remains. The general efficacy of abatacept, adalimumab, anakinra, certolizumab pegol, etanercept, infliximab, and rituximab for the treatment of rheumatoid arthritis was well established by multiple good to fair randomized controlled trials and meta-analyses. Effect sizes were large and consistent across studies. Targeted immune modulators 107 of 195 Final Update 3 Report Drug Effectiveness Review Project Juvenile Idiopathic Arthritis No head-to-head trial comparing the efficacy and safety of targeted immune modulators for the treatment juvenile idiopathic arthritis are available.
