(RxWiki News) Following a close vote, a U.S. Food and Drug Administration panel has declined to recommend rivaroxaban" data-scaytid="1">rivaroxaban (Xarelto) to treat acute coronary syndrome.
The FDA's Cardiovascular and Renal Drugs Advisory Committee voted 6-4, with one member abstaining, that the drug should not be recommended for formal FDA approval.
"Ask your doctor about approved treatments for acute coronary syndrome."
Rivaroxaban is an oral anticoagulant manufactured by Bayer. On July 1, it was FDA approved to treat deep vein thrombosis, blood clots deep within veins that can led to a blockage in a main artery in the lung, also called a pulmonary embolism.
Rivaroxaban also was given the green light to treat adults undergoing hip or knee replacement surgery.
Most recently, Bayer had asked the FDA to approve the medication to treat acute coronary syndrome, which describes any conditions brought on by sudden, reduced blood flow to the heart, including a heart attack. The most common symptom is chest pain.
The FDA panel had reviewed the results from Bayer's phase two ATLAS trial comprised of 3,491 patients, and the follow up ATLAS phase three trial, which included 15,526 patients.
Both of the randomized double-blind trials asked patients with acute coronary syndrome to take rivaroxaban and aspirin, or aspirin alone to determine whether the drug reduced cardiovascular events.
However, after reviewing the clinical trials, the panel determined there was "substantial missing data, poor follow-up, predominantly attributed to withdrawal of consent." It called the recent trend "distressing."
