"Roche was unduly impeded at this trial from adducing and advocating numerical proofs that could have potentially and reasonably led a jury to reach a different verdict," the appeals court said.
Around 13 million people have taken Accutane since its introduction in 1982. Roche lost the patent for the drug in 2002 and continued to sell it alongside its generic offerings. In 2009, however, the drugmaker pulled it from the market.
Roche has lost all seven of the cases regarding Accutane that have been decided by juries since 2007. According to the news source, juries have awarded at least $45 million in damages to the drug's users in those cases.
In addition to inflammatory bowel disease, Accutane has been linked to birth defects and depression.
