Ac Immune Sa
Ac Immune Sa is a Private limited company (Ltd.) registered in Switzerland under CHE109878825, and its current status with Zefix — Swiss Central Business Names Index is active. The company was incorporated on 13 February 2003 and lists its registered address as Lausanne, Switzerland. 1 shareholder is on record for Ac Immune Sa, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
