Drugs do work: Food and Drug Administration gave the green light to Benlyst

An advisory panel of the Food and Drug Administration gave the green light to Benlysta, the first treatment for the disease Lupus in half a century. This is likely to lead to full regulatory approval next month.

Shares in Glaxo surged 29.5p to 1243p on hopes that a potential multibillion windfall will offset some of the revenues GSK is set to lose over the coming years as older medicines lose their patent protection.

GSK is also withdrawing its blockbuster diabetes treatment Avandia from Europe, and is severely restricting sales in the US, after it was found to increase the risk of heart attack.

Global sales of Benlysta - developed in partnership with American biotech Human Genome Sciences - are forecast to soar to £1.4bn by 2014, with Glaxo taking a 50% share.
