For asthma, Glaxo plans to submit an application in Europe in mid-2012 and will continue discussions with the US Food and Drug Administration on the regulatory requirements for a US asthma indication.

The COPD programme included two 52-week "exacerbation" studies, each of which randomised approximately 1,620 patients. In the two studies in the COPD programme Relovair at all doses performed better than its comparator Vilanterol. Despite the success Glaxo is investigating reports of fatal pneumonia amongst patients who used Relovair, primarily at the 200/25mcg dose.

The asthma study programme is still waiting on results comparing the efficacy of Relovair against fluticasone propionate and a placebo. That study is expected to complete in the first half of 2012.

Glaxo admits a 24 week "superiority study" of Relovair against Seretide in asthma patients "did not meet the predefined threshold for superiority". Glaxo describes this study as "non-pivotal".

In the last 12 months GlaxoSmithKline shares have climbed 21%.
