Pfizer’s Lyrica is facing safety questions after a study published in Neurology this week documented a feasible link in between the med and birth defects as quickly as taken by pregnant women.
Supported by the American Academy of Neurology, the study investigated the discomfort and antiseizure drug, among Pfizer’s leading sellers, in 164 pregnant women in 7 countries. The group discovered that for women that took Lyrica throughout the very first trimester, “significant birth defects” were 3 times as most likely than for the women that didn’t take antiseizure meds. The outcomes were measured versus a group of 656 pregnant women not taking antiseizure drugs.
Seven from 116 pregnancies (6%) in the Lyrica group had significant birth defects, the authors said, compared to a birth defect fee for the larger group of 12 from 580 pregnancies (2%). The birth defects included problems along with the central nervous system, the heart and various other organs.
According to the investigators, the Lyrica group was 6 times much more most likely to have actually a CNS “significant defect.” The team noted four CNS complications from 125 pregnancies (3.2%) compared to 3 from 570 pregnancies (.5%) for the non-Lyrica arm.
As the authors admit, they can’t tempt “definitive conclusions” from the study “due to the fact that numerous of the women were taking various other drugs that could have actually played a role in the birth defects and due to the fact that the study was small.” However, the research–which will certainly have to confirmed along with bigger tests–signals “that there could be an increased risk for significant birth defects after taking pregabalin throughout the very first trimester of pregnancy,” author Ursula Winterfeld wrote in a statement.
In an email to FiercePharma, Pfizer cited the study’s “considerable limitations,” saying it “was small, did not account for various other medical conditions or medications, and the women taking Lyrica had greater speeds of smoking and diabetes, every one of which can easily negatively affect pregnancy outcomes.”
Approved by the FDA to treat epilepsy, fibromyalgia and neuropathic pain, Lyrica is additionally used off-label to manage stress and anxiety and various other psychological good health issues.
A stalwart for Pfizer’s pharma company for years, Lyrica brought in $3.6 billion last year. The company, which has actually been functioning to defend from generics, got in to hot water last September in the U.K. after wasting a crucial patent fight. According to a judge, letters it wrote to doctors and pharmacies that would certainly introduce a generic version of Lyrica were “calculated to have actually a chilling effect on the willingness of pharmacies to stock and dispense generic pregabalin.”
The drug was one among numerous by Pfizer whose prices jumped this year despite ongoing public stress versus drug fee hikes. According to reports, its fee jumped 9% to ring in the brand-new year.
