Bowing to congressional pressure, the U.S. Department of Health and Human Services (HHS) Wednesday filed suit against Gilead Sciences Inc. for infringing government patents related to the use of HIV drugs Truvada and Descovy for pre-exposure prophylaxis (PrEP).

Whether prescription drug prices are skyrocketing in the U.S. is a question of perspective and context. Patients needing regular refills of insulin or certain other brand drugs with no generics are seeing their out-of-pocket costs going up, sometimes with every trip to the pharmacy.

Those cheap prescription drug prices other countries get?

Shares in Aveo Pharmaceutical Inc. (NASDAQ:AVEO), commonly called Aveo Oncology, fell 36.7% Monday to 57 cents after the FDA dashed hopes that positive interim data from a late-stage study of tivozanib would overcome agency concerns about the drug's efficacy in relapsed/refractory renal cell carcinoma (RCC). Advised by the regulator not to submit an NDA at this time, Aveo now plans to collect more mature data ahead of filing its NDA in the first quarter of 2020. A discussion with the FDA's Oncologic Drug Advisory Committee will likely be required too, the agency said.

How vulnerable is the U.S. biopharma supply if China were to halt exports of active pharmaceutical ingredients (APIs)? No one knows. "We cannot assess the extent of U.S. dependence on China," Janet Woodcock, director of the FDA's Center for Drug Evaluation and Research (CDER), said in testimony to a House subcommittee Wednesday.

The third time is proving not to be so charming for Agile Therapeutics Inc. as it prepares its lead candidate for a date Wednesday with the FDA's Bone, Reproductive and Urologic Drugs Advisory Committee.

In another marathon session Tuesday, the third U.S. House committee with jurisdiction over prescription drug pricing issues marked up H.R. 3, the Lower Drug Costs Now Act, clearing the way for a House vote on the partisan measure yet this month.
