Gilead, Roche sue Natco Pharma over generic Tamiflu
NEW YORK — Drug makers Gilead Sciences and Roche are suing Indian drug maker Natco Pharma concerning a generic version of an influenza treatment, according to published reports.
Bloomberg reported that Gilead and Roche were accusing Natco of patent infringement due to its efforts to gain approval from the Food and Drug Administration for a generic version of Tamiflu (oseltamivir phosphate). Natco became the first company to file for approval of a generic version in February.
