The Scoop: Portola has aimed high, initially zeroing in on two programs--both now in mid-stage trials--that have potential best-in-class status built in. It's raised more than $200 million in venture capital and recently snared a major-league collaboration with Novartis.
What makes it Fierce: Last February Novartis agreed to pay $75 million upfront and an additional $500 million in prospective milestones for the worldwide rights to Portola's mid-stage anti-clotting therapeutic. In a clear sign that bright drug prospects can still command a hefty price in this market, Novartis is investing in a drug--dubbed elinogrel---that analysts believe can eventually compete with the blockbuster Plavix.
Currently in Phase II, elinogrel could act faster than Plavix, which would give the therapy a distinct edge in the market. And Portola has retained co-promotion rights in the U.S., hanging on to a considerable chuck of the therapy's value.
But that's just part of Portola's story.
Portola's other lead drug candidate is betrixaban, an oral anticoagulant that directly inhibits Factor Xa, a target in the blood coagulation pathway and a potential competitor to warfarin, an oral therapy with a long history of serious side effects. The therapy is in a Phase II trial with 500 patients for atrial fibrillation. Betrixaban is ripe for a partnership deal that is likely to rival the one posted for elinogrel.
"We may make it more back-ended because we have more cash," says CEO Charles Homcy. And you can expect Portola to hang on to copromotion rights just as it will seek out a big upside on royalties and development milestones.
Portola isn't just a two-program developer, though. There are three preclinical programs underway in thrombosis, cancer and inflammatory diseases.
Portola has proven to be immensely popular with its venture backers. A year ago the developer announced that it had raised $60 million in a Series D, which followed on $70 million from a Series C in 2007. Altogether Portola has raised $218 million in venture funds--there's $125 million to $130 million in the bank--which combined with the Novartis money will fund the company into 2011, even without a deal for betrixaban.
What to look for: Data, deals and new clinical trial programs. Homcy is hot on the trail of a new partnership for betrixaban. Mid-stage data is crucial to Portola's continued success. Elinogrel can wrap Phase II by the end of this year or early 2010 with a late-stage trial starting in late 2010. Betrixaban could also deliver mid-stage data by the end of this year. And Homcy has his eye on several preclinical programs that are getting closer to human trials, including a novel approach to dealing with the potential for bleeding from Factor Xa inhibitors.
