Amryt Pharma PLC ( LON:AMYT ) shares bounced on Wednesday after a ruling from the US bankruptcy court cleared the way for its acquisition of Aegerion Pharmaceuticals Inc. Orphan drug firm Amryt said once the approved plan of reorganisation came into effect, around 24 September, it would acquire Aegerion in exchange for its own stock, which would be distributed to certain creditors of the US firm.
