Portola Betrixaban Accepted for Review in U.S. & EU, Stock Up

Read MoreHide Full Article

Shares of Portola Pharmaceuticals, Inc. surged 33.8% after the company’s new drug application for its oral, once-daily Factor Xa inhibitor anticoagulant, betrixaban, was accepted under priority review by the FDA. Note that Portola is looking to get betrixaban approved for extended-duration prophylaxis of venous thromboembolism (VTE) in acute medically ill patients with risk factors for VTE.

Portola’s year-to-date share price movement shows that the stock has underperformed the Zacks classified Medical - Drugs industry. Specifically, Portola has plunged 51.3% during this period, while the industry lost 24.1%.

We note that priority review shortens the FDA review period from the standard 10 months to just 6 months. Therefore, with the FDA granting priority review, a final decision on the approval of the candidate should be out by Jun 24, 2017.

In addition, Portola’s marketing authorization application for betrixaban for extended-duration prophylaxis of VTE in adults with acute medical illness and risk factors for VTE was validated by the European Medicines Agency (EMA). The EMA's Committee for Medicinal Products for Human Use will review the regulatory application during a standard 210-day review period.

We are encouraged by the simultaneous acceptance of betrixaban for review in the U.S. and the EU. These approvals will be a huge boost for the company seeing that betrixaban will be the first anticoagulant to be approved for in-hospital and extended-duration VTE prophylaxis in high-risk acute medically ill patients.

According to information provided by the company in its press release, an estimated 24 million acute medically ill patients are hospitalized annually in the G7 countries and are at risk of developing VTE, either while in the hospital or following discharge. Moreover, regardless of the standard use of injectable enoxaparin and other heparins in the hospital, over 1 million VTEs and 150,000 VTE-related deaths occur each year in these patients in the G7 countries.

Portola’s stock got a much-needed boost from the latest development. We remind investors that the company’s shares were under pressure ever since this August, when the FDA issued a complete response letter for AndexXa (EU trade name: IndexXa), which was being developed as an antidote for Factor Xa inhibitors, in cases where reversal of anticoagulation is needed due to life-threatening bleeding or when urgent surgery is required.

PORTOLA PHARMA Price and Consensus

 

Portola plans to resubmit the biologics license application for AndexXa in the second quarter of 2017.

AndexXa is currently under review in the EU with a response expected next year. Portola is seeking conditional approval for AndexXa in the EU through the centralized procedure.

Note that Portola recently signed a $50 million loan agreement with Bristol-Myers Squibb Company (BMY - Free Report) and Pfizer Inc. (PFE - Free Report) , under which Bristol-Myers and Pfizer will each loan Portola $25 million for development and clinical studies on AndexXa. We note that Portola had previously entered into clinical collaboration agreements with Bristol-Myers and Pfizer to support phase II and registrational studies on AndexXa in the U.S. and Europe.

Moreover, it has a collaboration agreement with these two companies for the development and commercialization of AndexXa in Japan.

Currently available anticoagulants in the market include Bristol-Myers/Pfizer’s Eliquis among others.
