Analysts and investors also questioned the relationship structure, in which Valeant was Philidor's primary source of business and owned an option to acquire it. When Valeant cut ties with Philidor, it said Philidor would cease operating.
On Oct. 21, short seller Citron Research issued a report comparing Valeant to Enron, suggesting it was using Philidor and other specialty pharmacies to commit accounting fraud. Valeant said it believed its accounting of Philidor was appropriate, but appointed a committee of some of its directors to review allegations about its relationship with the specialty pharmacy.
At the end of October, pharmacy benefits managers CVS Health,Express Scripts, and UnitedHealth's OptumRx said they would stop working with Philidor.
Valeant is also the target of multiple federal investigations into its drug pricing practices. The company said Oct. 14 that it had responded to a letter from Sen. Claire McCaskill, D-Mo., and that it had received subpoenas from the U.S. Attorney's offices in Massachusetts and New York concerning its patient assistance programs and pricing decisions, among other things.
One of the services Philidor provided for Valeant was administration of copay assistance, a way for Valeant to pay patients' out-of-pocket costs when insurers set an amount often designed to deter patients from using certain drugs. The company said its agreement with Walgreens will include reduced or zero copays for patients with commercial insurance. Patients with government insurance aren't eligible due to federal regulations.
