Sanofi-Aventis Sends Warning Letter on Multaq Liver Failures
Pharmaceutical giant Sanofi-Aventis SA sent a letter to doctors in the US in January 2011, alerting them to recent findings showing that their heart drug, Multaq had been linked to multiple cases of acute liver failure. These documented cases of Multaq related liver failure were of a nature so severe, as to require liver transplants to save the lives of those Multaq patients cited in the warning letter from Sanofi.
In the letter, France’s largest drugmaker, Sanofi-Aventis SA, informed doctors about liver function test results and injuries involving toxicity reported by patients treated with Sanofi’s Multaq, including two cases of acute liver failure, a company spokesman said. Sanofi-Aventis SA currently denies a causal relationship between Multaq and liver toxicity and failure.
During the past 60 days, Sanofi-Aventis SA has been issued two Official Warning Letters from the FDA regarding related violations. One warning letter from the FDA was issued regarding violations in manufacturing processes at the Sanofi-Aventis manufacturing facility, and one dated January 28, 2011 specifically dealing with violations in their reporting of adverse reactions to their drugs. The drug Multaq was one of the specific drugs cited in this FDA Warning letter to Sanofi regarding their violation in the reporting of adverse effects. Sources have stated that the severe adverse effects of Multaq related liver complications have been downplayed.
According to Sanofi, almost 200,000 patients worldwide have been prescribed Multaq since it was first approved and introduced in 2009. Sanofi was hoping that sales of Multaq would help offset losses in revenue resulting from products, including the blood-thinner Plavix and the cancer treatment Taxotere, facing stiff competition from generic drugs. Bloomberg analysts projected that Sanofi-Aventis’ revenues from Multaq would reach $1.1 billion by 2013.
Speaking of the latest liver failure news from Sanofi, “Multaq will be an important drug over the next 10 years” for Sanofi and the treatment “cannot afford to face serious side effects that are tough to resolve,” Eric Le Berrigaud, an analyst at Raymond James in Paris, wrote in note to clients in January.
Multaq was approved by the FDA for sale in the US in 2009. Multaq is designed to treat atrial fibrillation, which is an irregular and/or rapid beating in the upper chambers of the heart. According to the National Heart, Lung and Blood Institute, atrial fibrillation affects an estimated 2 million people in the U.S.
In an FDA Statement, Multaq was tied to acute liver failure, requiring liver transplants, in two women. The U.S. Food and Drug Administration published this notice on its website. According to the FDA, Sanofi has said that it will provide additional information about liver risks associated with Multaq to the “warnings and precautions” and “adverse reactions” sections of its Multaq prescribing information.
Sanofi reports that it is working closely with the European Medicines Agency in London and other health authorities to review this matter.
Multaq sales in the U.S. reached $115 million during the first three quarters of 2010, according to a company report published on Oct. 28, 2010. These results were a disappointment according to some analysts, who say it as lagging behind expectations for the drug.
One financial analyst speculated that Multaq’s struggle to penetrate the U.S. market is not expected to benefit from this bad news related to multiple cases of acute liver failure, involving liver transplants.
Multaq was originally designed to be a safer alternative to the drug amiodarone, a generic medicine with serious liver and lung risks that is currently only approved for life-threatening irregular beating in the heart’s lower chambers. “Amiodarone includes a black box label citing various toxicities including severe liver toxicity,” wrote Seamus Fernandez, an analyst with Leerink Swann Research, in a note to investors.
Recently, Sanofi and U.S. partner Bristol-Myers Squibb Co. voluntarily recalled 64 million tablets of their Avalide blood pressure drug due to other safety concerns.
Multaq Class Action Lawsuit vs. Individual Multaq Lawsuit
There are strong differences between a class action lawsuit and an individual lawsuit. In the case of Multaq, a Multaq liver failure class action lawsuit would be a form of Multaq lawsuit in which a large group of plaintiffs would form a “class” and collectively bring a lawsuit to court against a defendant, which in this case would be Sanofi-Aventis, the manufacturer of Multaq. In a class action lawsuit involving personal injury from defective drugs like Multaq, all potential Multaq liver failure lawsuit plaintiffs would be grouped into a single Multaq liver failure class action lawsuit. This grouping into a class would happen regardless of degree or severity of liver toxicity injuries.
In a Multaq liver failure class action lawsuit, plaintiffs with injuries from minor ones all the way to the most severe acute liver failure toxicity cases requiring a complete liver transplant, would be grouped into one single Multaq class action lawsuit. Plaintiffs in this class would share any award or settlement resulting from the Multaq liver failure class action lawsuit.
Multaq liver failure lawsuits involving catastrophic injury or death would in most cases be better served by an individual lawsuit. Because of the severity and degree of injury to the plaintiff by Multaq, an individual lawsuit would be in the plaintiff’s best interest . Dangerous drugs like Multaq have been linked to severe liver injuries, including acute liver failure, which often times requires surgery and extensive medical care. In an individual Multaq acute hepatic failure lawsuit, each plaintiff’s case is filed, presented and considered individually, on a case by case basis, solely on its own strength and degree of liver toxicity injury.
In many cases involving Multaq, surgery is required. An individual Multaq liver failure lawsuit allows each Multaq liver failure victim to be thoroughly considered on an individual basis when determining damages, awards and potential settlement amounts, based on their own toxicity injuries and future needs, and not as part of a grouped class action lawsuit.

Children born with cardiac and other congenital birth defects have potentially been linked to use of the SSRI class of antidepressant drugs, including Lexapro (Generic: escitalopram). Research suggests serious Lexapro side effects, including the increased risk of congenital heart defects and other congenital birth defects. This link between SSRI antidepressants like Lexapro (escitalopram) and congenital heart defects has many professional concerned that women should not be prescribed the medication Lexapro (escitalopram) or other SSRIs during pregnancy. In addition to serious congenital Heart Birth Defects, SSRIs like Lexapro, Celexa, Prozac, Zoloft and Paxil have also been linked to increased risk of Persistent Pulmonary Hypertension of the Newborn (PPHN).
