The pharmaceutical company behind Martin Shkreli's infamous 4,000 percent price hike—now known as Vyera Pharmaceuticals—filed for bankruptcy this week and plans to sell its assets to pay off millions in debts.

In court documents filed Wednesday , Vyera's chief restructuring officer, Lawrence Perkins, largely blamed Shkreli for dooming the company and its affiliates.

"Upon information and belief, Shkreli’s actions have caused serious reputational harm to [the companies] and have hampered [their] ability to, among other things, open certain bank accounts, successfully commercialize new products, and either raise capital or consummate the sale of various [company] assets," Perkins wrote in an affidavit.

In Congressional testimony Wednesday, Moderna CEO Stéphane Bancel unabashedly defended the company's plans to raise the US list price of its COVID-19 vaccines by more than 400 percent—despite creating the vaccine in partnership with the National Institutes of Health, receiving $1.7 billion in federal grant money for clinical development, and making roughly $36 billion from worldwide sales.

Bancel appeared this morning before the Senate's Health, Education, Labor, and Pensions committee, chaired by Sen. Bernie Sanders (I-Vt.), who has long railed at the pharmaceutical price gouging in the US and pushed from policy reforms. After thanking Bancel for agreeing to testify, Sanders didn't pull any punches. He accused Moderna of "profiteering" and sharing in the "unprecedented level of corporate greed" seen in the pharmaceutical industry generally.

Sanders contrasted a recent survey finding that 37 percent of Americans can't afford their prescription drugs to the billions of dollars in profits reaped by drug companies. He noted several times that Bancel became a billionaire overnight amid the pandemic. Bancel is now estimated to be worth over $4 billion, Sanders added.
