Missing data

Lead researcher Joseph Ross said drug companies that delay publishing these findings, or even deliberately hide trial data, are breaching their ethical duty. “The evidence we publish shows that the current situation is a disservice to research participants, patients, health systems, and the whole endeavor of clinical medicine,” he said.

Data from these trials could provide vital information, such as evidence that a drug is dangerous. For example, Bayer faces lawsuits from women who say that the company was aware that its birth control pills Yaz and Yasmin put them at greater risk than other pills for suffering serious health problems, including blood clots, heart attacks, strokes and gallbladder damage. The company insisted that its oral contraceptives were no more dangerous than other pills. However, newly released studies show that the pills are more risky than older generation birth control pills.

In fact, during a Food and Drug Administration (FDA) advisory committee meeting reviewing the safety concerns associated with Yaz and Yasmin, the former FDA chief testified that Bayer withheld pertinent data on Yasmin and the increased risk for blood clots. (The committee recently recommended that stronger warnings be placed on the packages of Yaz and Yasmin, telling women that studies show the pills carry a greater risk for blood clots that can lead to serious health problems and even death.)

Yaz and Yasmin are among the top selling birth control pills in the United States and the United Kingdom; however, recent press about the drug’s link to blood clots has led to a drop in sales.

“Most clinicians assume that the complex regulatory systems that govern human research ensure that (clinical data) is relevant, reliable and properly disseminated,” Dr. Richard Lehman from Oxford University and the British Medical Journal’s Dr. Elizabeth Loder told the Daily Mail. “It generally comes as a shock to clinicians, and certainly to the public, to learn that this is far from the case.”

While the drug has yet to be approved for use in the United States, the possibility of a male birth control medication is creating a buzz. Researchers are already testing various contraceptive pills, patches, creams, and implants on men, and it is strongly believed that a male birth control pill could be available in the United States within 5 to 7 years, and implants could hit the market even sooner.

Researchers say data shows that contraceptives that combine progestin and androgen are safe, effective, inexpensive and reversible. However, proof of the drugs’ initial safety profile will be determined when clinical trials are completed.

Hormone birth control for women is known to slightly increase the risk for blood clots, which can lead to more serious problems such as heart attacks, strokes, and even death. Some studies suggest that a newer generation of pills – those that contain the hormone drospirenone – put women at even greater risk for blood clots. Those pills include the brands Yaz, Yasmin, Ocella, Beyaz, and Safyral, as well as their generic equivalents.

The male contraceptives are currently being tested in China, but researchers say they hope to conduct clinical trials in the United States within the next two years.

Yaz incorporates a unique progestin, drospirenone, with ethinyl estradiol, a more common ingredient used in birth control drugs. Many women who have been injured after starting a Yaz regimen allege that the drug poses a multitude of serious risks, which Bayer downplayed in its Yaz marketing campaigns.

The U.S. Food and Drug Administration admonished Bayer in October 2008, citing the company for “significant deviations” in its promotion of Yaz. The complaint largely centered on the understatement of the drug’s risks and the overstatement of its benefits, including the treatment of conditions for which the drug was not approved. The misleading marketing campaign is frequently cited in lawsuits brought against Bayer by former Yaz users.

Some of the most serious side effects associated with Yaz include stroke, heart arrhythmia cardiac arrest, deep vein thrombosis and other forms of blood clotting, pulmonary embolism, gallbladder disease, kidney damage or failure, and sudden death.

Judge Herndon told Southwestern Illinois’ Belleville News-Democrat that he may also conduct bellwether trials, a cluster of cases selected because they reflect the charges and allegations of the other lawsuits. The outcome of bellwether trials helps establish guidelines for other cases.

When a significant number of similar lawsuits, such as those being brought against Bayer over Yaz injuries, accumulate in federal courts, the Judicial Panel on Multidistrict Litigation normally moves to consolidate them in one U.S. District Court to avoid redundant efforts and inconsistent pre-trial rulings. The dynamics of these representative trials will then be considered in the evaluation of other cases.

The plaintiff, who resides in Belpre, Ohio, had been taking Yaz for about a year when she developed deep vein thrombosis in her leg. She spent three days in the hospital, where like many other women who use Yaz, she was put on a regimen of blood thinners to dissolve the clot and reduce the swelling in her leg.

Deep vein thrombosis (DVT) is a very serious type of blood clot that can lead to serious complications and death if not treated properly. Clots that form a DVT can become dislodged, traveling through the bloodstream to the lungs and causing a pulmonary embolism, resulting in permanent damage to the lung. DVT can also cause stroke, cardiac arrest, and other potentially deadly conditions.

Yaz contains drospirenone, a synthetic progestin used in Yaz, Yasmin, and Ocella, which is a generic form of Yasmin. Drospirenone has been shown to increase potassium levels in some women who take the drug, which can lead to DVT and affect the function of several organs, including the heart.

The Ohio plaintiff’s lawsuit was filed in New Jersey Superior Court. The suit alleges that the plaintiff’s injuries were the result of Bayer’s failure to adequately warn consumers of the drug’s risks. Her attorney claims that Bayer knew Yaz to be more dangerous than other birth-control pills, but chose to downplay the drug’s hazards.

The plaintiff began taking Yaz after her gynecologist reassured her of the drug’s benefits and safety. After weeks of using Yaz, however, the woman began experiencing severe pain that sent her to the emergency room twice for general treatment and CT scans.

It took 13 hours for doctors to finally discover the problem. According to the Times, “In her left lung, the pulmonologist told her, was the largest blood clot they had ever seen and there were others in her right lung as well.”

The woman spent 6 days in the hospital as she was treated with 2 types of blood thinners to dissolve the clots in her lungs. Doctors expected a good recovery but told her that she might never be completely the same . Two weeks after the treatment, she told the Times that she is “incredibly tired most of the time.”

The plaintiff said that a couple of days after the treatment the severity of her situation suddenly hit her. “Wow, I almost died,” she told the Times. Now she strives to tell others about how Yaz affected her and has put the lives of so many other women in danger.

“It’s not just about women who are my age,” she told the Times, adding that lots of younger women are being seriously injured by the drug.

“There’s no reason for blood clots to be forming except for this pill and it’s a very scary situation,” she said.

Bayer has defended itself and Yaz against the allegations, pointing to the two Bayer-funded studies that showed the drug had a safety profile similar to other, more traditional oral contraceptives.

Another Yaz study, not funded by Bayer, found women who took Yaz to be more at risk for blood clots, heart attacks, and strokes. Those results were echoed by a more recent study published by the British Medical Journal in August.

“She was short of breath. She was having severe chest pains and her face was changing colors,” Kraus told WTAE.

“She ended up going into cardiac arrest three times. One time it took 10 minutes to revive her. They eventually had to do emergency surgeries because they noticed there were two huge blood clots, one in each pulmonary artery,” Kraus said.

Kraus said that because of Yaz, her daughter now faces possibly lifelong struggles with pancreatitis, liver function problems, and acute kidney failure. Kraus and the other plaintiffs have requested a jury trial, more than $150,000 in compensation, attorney fees, court costs, and punitive damages.

Bayer Corporation, which is headquartered in Pittsburgh, defended itself from the allegations in a statement to WTAE.

“The complaints we have reviewed so far pertain to side effects that are warned about in the labeling of all contraceptives. Bayer will defend itself vigorously against these lawsuits,” a company spokesman said.

The lawsuit, however, alleges that Bayer grossly downplayed the risks of Yaz in its advertising campaigns and that the number of adverse events caused by Yaz is at least 10 times more than the number reported incidents, possibly 100 times more.

“I just don’t want anybody else to see their child go through anything like this ever again,” Kraus told WTAE.

Development of gall stones and gall bladder disease are among the serious risks associated with the oral contraceptive Yaz. The drug has also been blamed for elevating the risk of cardiac arrhythmias and heart attack, stroke, pulmonary embolism, blood clots, kidney failure, seizures, deep vein thrombosis, hepatic adenomas and sudden death.

According to the lawsuit, 50 deaths attributed to the use of Yaz and Yasmin were reported to the U.S. Food and Drug Administration between the first quarter of 2004 and the third quarter of 2008.

The lawsuit alleges that Bayer markets Yaz and Yasmin “as providing the same efficacy as other birth control pills in preventing pregnancy, but with additional benefits,” rather than the higher risks the drugs pose.

“The foreseeable risks of the product exceeded the benefits associated with its design or formulation. Or they were more dangerous than an ordinary consumer would expect,” the lawsuit states.

The plaintiff seeks compensatory and punitive damages, medical expenses and economic damages, and attorney’s fees. Because Bayer ran a deceptive ad campaign for Yaz, hailing the drug for uses unapproved by the FDA while downplaying its risks, the plaintiff also seeks an unspecified amount of punitive damages.

The plaintiff claims that at the time, she was not aware the FDA had not approved Yaz for the treatment of skin conditions. In an extensive and aggressive marketing campaign, Bayer touted its birth control drug as an effective treatment for acne and symptoms associated with Premenstrual Syndrome (PMS) – conditions for which the FDA never tested or approved Yaz.

In October 2008, FDA officials warned Bayer that its Yaz ads intentionally mislead and confused viewers by overstating the drug’s effectiveness, overselling its benefits, and not adequately communicating the drug’s potential for serious side effects, including blood clots, cardiac arrest, and gallbladder disease. According to the FDA, the commercials used distracting visuals, multiple scene changes, and background music that effectively interfered with the audio presentation about the serious risks associated with the drug.

“Bayer promoted Yaz with the slogan ‘the difference a little chemistry can make,’” the plaintiff said. “What Bayer did not disclose was how negative that difference can be. Yaz gave me life-threatening injuries that have forever altered my life.”

After several months of Yaz therapy, the plaintiff developed an acute pain in her left shoulder and had difficulty breathing. A visit to the doctor revealed the plaintiff had developed blood clots in both her lungs. She was hospitalized immediately and treated successfully, but just one month later she developed gallstones and had to undergo surgery for their removal.

The plaintiff alleges that she “suffered months of anxiety and nausea related to (the) medical procedures and drugs given to treat the adverse side effects (she) developed from taking Yaz.”

The complaint charges that had Bayer properly warned patients about the dangers of using Yaz strictly as an acne treatment, the plaintiff could have avoided serious injury.

The lawsuit was filed in the Superior Court of New Jersey, where Bayer’s American operations are based. The plaintiff seeks an unspecified amount of compensatory damages.

Pulmonary embolisms are blockages in one of the arteries leading to the lungs formed by a substance that has migrated through the bloodstream from another part of the body, commonly the legs. Clinical studies of Yaz conducted in Denmark and the Netherlands suggest a link between the Yaz ingredient drosperinone and a higher occurrence of blood clots than in women who took traditional contraceptives containing levonorgestrel.

A spokesperson for Bayer said that the company is cooperating with the investigation, but that it stood by the safety of its drug.

“A singular case, as tragic and sad as it is, does not indicate an increased risk for the whole group of women who take the pill,” Oliver Renner, a Bayer spokesman, told Bloomberg. “Studies have shown that the risk isn’t higher for Yaz than for other oral contraceptives.”

Of course, Bayer’s spokesperson dismisses the results of the two independent clinical trials and focuses on the more favorable outcome the Bayer-funded clinical test, which suggested the risks of Yaz were similar to those of traditional birth control therapies.

As the top selling oral contraceptive in the world, Yaz is big business for Bayer. The drug brought in $1.86 billion just in the first quarter of 2009.
