Johnson & Johnson (JNJ) and Bayer AG (BAYN) failed to win approval to expand use of their blood thinner Xarelto to prevent heart attacks and strokes in patients with serious chest pain or history of cardiac illness.
The U.S. Food and Drug Administration raised questions about Xarelto’s use in reducing the risks for patients with acute coronary syndrome, Johnson & Johnson said in a statement. Xarelto was approved in July 2011 to prevent blood clots in patients undergoing knee and hip surgeries and its use has since been expanded to patients with irregular heartbeats and deadly leg and lung blood clots.
Acute coronary syndrome is an umbrella term for situations when the blood supplied to the heart is blocked, according to the American Heart Association. The condition leads to 1.2 million hospitalizations each year. AstraZeneca Plc (AZN)’s Brilinta and Eli Lilly & Co. (LLY)’s Effient have already been on the market as a treatment for acute coronary syndrome.
J&J shares rose less than 1 percent to $77.66 at the close in New York. Bayer gained 3.2 percent to 77.99 euros in Frankfurt trading.
The FDA last year had rejected the expanded use application by New Brunswick, New Jersey-based J&J and Leverkusen, Germany- based Bayer. Agency advisers who had recommended against approval in May, cited missing data from 1,000 patients who withdrew from a late-stage trial of the drug.
J&J owns rights to the medicine while Bayer sells the drug in Europe.
Xarelto is one of the medicines being promoted to replace warfarin, a more than 50-year-old drug that requires constant monitoring and dose adjustments to keep blood from getting too thin and putting patients at risk of severe bleeding.
