Idenix Inks HIV-Drug Deal with GSK Worth up to $450M
Rebecca Zacks 2/6/09
Shares of Idenix Pharmaceuticals (NASDAQ: IDIX) jumped in pre-market trading this morning on the news that the Cambridge, MA-based developer of treatments for infectious diseases has inked a deal with pharma giant GlaxoSmithKline potentially worth some $450 million.
GSK will pay Idenix $34 million upfront—half as cash and half via a purchase of its stock at $6.87 a share, a premium over yesterday’s close of $6.44—for exclusive worldwide rights to the Massachusetts firm’s HIV drug IDX899. The drug, a member of a class called non-nucleoside reverse transcriptase inhibitors, is in mid-stage trials as a once-a-day treatment for HIV/AIDS. Idenix is also poised to collect up to $416 million in milestone payments tied to the development, regulatory approval, and sales of the drug, and it will be entitled to “double-digit, tiered worldwide royalties” as well, according to a press release.
Idenix shared opened at $6.74, up 4.7% from yesterday’s close. The upfront money from GSK represents a sizable addition to Idenix’s coffers, which held about with $45 million to $50 million at year’s end.
