Pfizer and Bristol-Myers Squibb have halted a trial of their heart drug apixaban after signs of increased risk of bleeding.
The drug is one of a new generation of anticoagulants blood thinner now reaching patients which aim to improve care for a range of heart patients.
But data showed the drug produced an increased risk of in bleeding which outweighed benefits for patients who suffered from acute coronary syndrome.
Enrollment in the Appraise-2 study of 10,800 people in 40 countries was stopped and patients will be taken off the drug,
The co-developers say work on apixabanโs approval for the prevention of strokes in patients with irregular heartbeats and clots in those who have undergone hip and knee replacement.
The halted study, called Appraise-2, was designed to prevent recurrent episodes in patients with heart attacks and acute blood vessel blockages. Patients who suffer such attacks are especially vulnerable to have a repeat event in the following months. About 733,000 Americans are released from the hospital each year with the condition.
The failure of apixaban for ACS did not come as a surprise to experts in the field, as the condition is notoriously tricky to treat without raising the risk of bleeding.
Analysts still predict will be a major earner for the partners, with sales forecasts of up to $1.7 billion in sales for the two companies in 2015, thanks to expected use in atrial fibrillation and VTE prevention.
