Science in the Triangle

Salix Pharmaceuticals watches its stock soar and Pozen takes action to broaden the scope of the company while GlaxoSmithKline waits for regulatory approval of two vaccines.

Salix soars on rifaximin data

Shares of Salix Pharmaceuticals are up more than 50 percent since the Morrisville company, which specializes in gastrointestinal treatments, announced results from two late-stage studies.

The studies showed rifaximin works better than placebo in treating non-constipation irritable bowel syndrome. Salix already sells rifaximin for traveler’s diarrhea under the name Xifaxan.

Treatments for non-constipation IBS generate about $2.2 billion in annual sales, but patients and doctors are looking for more choices with fewer side effects.

Salix stock dropped below $6 a year ago as the company struggled with generic competition. The day the rifaximin study results came out, Salix shares soared as high as $21.34. Since then, they’ve been close to $20 and attracting the attention of Credit Suisse pharmaceuticals analyst Catherine Arnold, who has tagged Salix an appetizing acquisition target for large drugmakers looking to boost revenue.

Pozen hires executive to broaden its scope

Pozen, a Chapel Hill drug development company, hired a chief commercial officer to develop licensing and marketing strategies for its drugs in development. Elizabeth Cermack, a former Johnson & Johnson executive, specializes in sales and marketing.

Founded in 1996, Pozen has long relied on partnerships with large drugmaker to help develop and market its medicines. Migraine pill Treximet, its first drug to receive regulatory approval, is sold by GlaxoSmithKline, which also helped develop it. Pozen also has a partnership with AstraZeneca to develop and bring to market Vimovo, an experimental painkiller that is easy on the stomach.

But the company, which never ventured into sales and marketing before, recently announced plans to broaden its scope and fly solo bringing to market its family of aspirins that promise to be gentler on the stomach.

GSK waits while competition gets ahead

GlaxoSmithKline, which has its U.S. headquarters in Research Triangle Park, hopes to get approval for Cervarix, a vaccine that blocks a major risk factor for cervical cancer, before the end of the month.

A Food and Drug Administration panel recently recommended the vaccine get cleared for sale after a series of delays. If the FDA follows the recommendation, Cervarix would become available in the U.S. three years after Merck’s version Gardasil was approved.

GSK is also still awaiting FDA approval of its H1N1 vaccine. Four competitors already got the regulatory nod.
