TDF (tenofovir disproxil fumarate)/Viread Lawsuits

Gilead markets their TDF drugs under the brand names Atripla, Complera, Stribild, Truvada, and Viread. In their lawsuits, HIV patients assert that Gilead didn’t warn them of potentially life-threatening side effects. In addition, plaintiffs claim that Gilead purposely prevented a safer version of its medications from going to market in order to maximize profits from sales of TDF-based medications. Gilead’s motive for holding back a safer alternative therapy was pure greed.

The national law firm of Baron & Budd has battled appalling corporate behavior such as Gilead’s for more than forty years. If you were prescribed a tenofovir DF medication and suffered severe side effects as a result, we may be able to help.

How TDF Works

Human immunodeficiency virus is a persistent opportunistic infection which attacks the body’s immune system. Without medication to hold infection in check, HIV rapidly multiplies throughout the body, destroying immune cells and leaving patients susceptible to severe and potentially deadly infections.

The U.S. Food and Drug Administration (FDA) approved tenofovir DF for use in adults in 2001. TDF is designed to block the formation of an enzyme that allows the virus to multiply and can help reduce the severity of the HIV infection. This helps patients control their virus and enables them to lead long term healthier lives while also lowering the risk of infection to others.

Gilead Antiviral Medication

Severe Problems

The use of tenofovir DF has been linked to a buildup of lactic acid in the blood, called lactic acidosis, severe liver problems, kidney failure, and bone injuries. Japanese researchers published a study in 2017 which found that TDF use can lead to chronic kidney disease. According to scientists, prolonged use of the drug increases the risk of developing a potentially life-threatening condition. TDF use may also increase a patient’s risk for bone loss. A Stanford University study in 2016 found greater bone mineral density loss associated with TDF than with tenofovir alafenamide fumarate (TAF). A 2018 study published in the journal Clinical Science revealed that patients who were prescribed medications containing tenofovir DF suffered substantially more loss of hip bone density.

What Did Gilead Know?

LA Times Article

The Los Angeles Times reported in 2018 that HIV patients are suing Gilead Sciences, Inc. for damages related to the medical complications they’ve suffered after taking tenofovir DF. In the article, plaintiffs claim that Gilead scientists knew as early as 2001 that TDF could lead to serious kidney disease and bone loss. That means Gilead officials were aware of the potential for harm at the time their TDF drugs, including Viread, first came on the market.

Gilead scientists, according to the report, had also been developing a different version of the drug using a substance known as tenofovir alafenamide fumarate, or TAF. Studies involving TAF show that it is not only less toxic than TDF, but also more effective in keeping the HIV virus from multiplying.

Plaintiffs in TDF lawsuits allege that Gilead purposely suppressed information about the dangers of tenofovir DF. At the same time, officials at Gilead also withheld information about the safer alternative drug TAF, all in order to maximize TDF sales before its patent expired.
