Edmond de Rothschild Investment Partners is sticking with its investment strategy for the firm's fourth dedicated life sciences fund - an approach that has allowed it to return money to LPs every year since 2004 and has it on track for an IRR of 20% for its previous two life science funds.

The firm was to announce on Monday this week that it has closed BioDiscovery 4 at €192 million ($265.2 million). EdRIP raised €125 million ($153.6 million) in an initial close last year.
