The formula for rising healthcare costs in the US is filled with a bunch of pointed fingers lately. One finger is being pointed at drug maker Kaléo (no, not that Kaleo) by pharmacy benefit manager Express Scripts. They’re suing Kaléo over its price hikes on a heroin/painkiller overdose treatment. According to Express Scripts, these hikes triggered price protection rebates owed to Express Scripts, which total around $14 million—most of the lawsuit. The PBM has successfully sued larger drug companies like Horizon, so Kaléo may be at a bit of a disadvantage here. Especially since Express Scripts could use the extra cash to deal with the fingers pointed at it, including one $15B lawsuit by its (soon-to-be former) largest customer, the insurance provider Anthem.
