Sanjay Kumar, a 43-year-old man from Bihar, India, has been indicted for allegedly selling counterfeit cancer drugs, including Keytruda, in the United States. He was arrested in Houston while negotiating further deals for his illicit business, which reportedly involved tens of thousands of dollars in fake oncology pharmaceuticals. Kumar faces one count of conspiracy to traffic in counterfeit goods and four counts of trafficking in counterfeit drugs, which could result in up to 20 years in prison for each count. His defense attorney claims the government will struggle to prove that Kumar knowingly shipped counterfeit medications. Merck Sharp & Dohme LLC, the legitimate manufacturer of Keytruda, confirmed that the counterfeit vials lacked active ingredients and were not authorized for sale. The case highlights growing concerns over counterfeit drugs infiltrating the U.S. healthcare system.
