Actelion, Europe's largest biotech company, has the backing of Rudolf Maag, one its largest shareholders, a spokeswoman for Maag said on Monday.

The company is coming under pressure from hedge fund activist Elliott Advisors ahead of the group's annual general meeting in May.
Elliott, Actelion's biggest shareholder with a near 6% stake, is dissatisfied with the group's performance and is pushing Actelion to consider selling itself.
