EP Vantage submits:To coin a L’Oréal phrase, in the eyes of Astellas Pharma (ALPMF.PK), OSI Pharmaceuticals (OSIP) is definitely ‘worth it’. Having conducted its due diligence of OSI’s private books, Astellas Sunday raised its original hostile offer of $52 cash per share to an accepted bid of $57.50 cash per share, valuing the deal at $4bn, the second biggest overseas acquisition by a Japanese pharma company.Big sighs of relief all round then at Astellas, who failed to land CV Therapeutics last year and adopted a slightly risky approach to bidding for OSI. But it now looks set to increase its presence in the US market and gain a portfolio of marketed and pipeline cancer drugs, most notably lung cancer drug Tarceva.
