Selective criteria hold back Sovaldi use
Medimpact, a PBM, has chosen to be selective about hepatitis C drugs to keep costs down. Steve Avey, vice president, specialty clinical services, found that after conferring with experts, it doesn’t make sense to treat everyone with the virus. “It costs a lot to give new expensive drugs to everyone who is infected with hepatitis C, when they might not have liver disease or a high enough viral load,” he says.
Medimpact deploys strict criteria for using Sovaldi resulting in a low rate of approval. Avey attributes more substantial rebates for Sovaldi to stricter guidelines developed by insurers and PBMs. However, some states have mandated which patients are candidates for the drug, forcing the PBM to broaden its criteria.
Avey says it is imperative that true clinical value for drugs such as Sovaldi are worthy of their high price. That’s why MedImpact clinically vets these products both internally and with external experts to provide clients with clinically and financially sound strategies at the time of product launch.
The PBM creates prior authorizations based on the exact inclusion and exclusion criteria of clinical studies. “These tight clinical parameters ensure that the studied population is the one that actually takes the drug. We also limit off-label use,” he says.
Avey expects oncology drug spend to escalate over the next 10 years. “This will far outweigh the hepatitis C challenge due to the number of people involved, the duration of therapy and the multi-drug approaches,” he says.
To address the high costs of oncology, Medimpact ensures that medications prescribed on day one are still effective six months later. Patients also receive calls within eight days of starting an oncology regimen and if problems prevail, doctors are notified.
In addition, all oncology medications must be accompanied by clinical services to avoid discontinuation and mitigate side effects, be filled at a specialty pharmacy and utilize a split-pill program of 15 pills costing half a copayment for the first two months of therapy.
In the RA space, Humira is the most-costly drug for the PBM, prompting it to use a preferred drug strategy to reduce costs and drive higher rebates, and step therapy before moving onto more complex drugs, says Avey. Medimpact also assesses therapy prior to dose escalation if clinical benefit is still not confirmed and recommends contracting to prevent huge price increases for RA drugs in future years.
Across the board for all specialty drugs, the PBM deploys Medimpact Direct to help answer challenges related to fulfillment: reducing member disruption by determining the most appropriate place to fill a prescription; eliminating “free first, 30-day supply” programs to avoid initiating patient on a more expensive therapy; and ensuring that the recorded amount of copayment/coinsurance paid by a plan member matches the actual amounts.
Finally, its quarterly clinical surveillance program reviews all specialty drugs for all clients and looks for gaps in care; ineffective protocols; overutilization; patients who have dropped off medications; and claims potentially causing fraud, waste or abuse.
Sometimes the answer is ‘no’
Sean Sullivan, dean, School of Pharmacy, University of Washington in Seattle, recommends three main strategies for all specialty pharmacy:
1. Just say “no” to coverage of certain drugs. Sullivan calls this “prior authorization on steroids.” While you can’t say no if there is only one choice, you can limit choices, he says.
2. Lockdown specialty provider networks into closed delivery systems. If a manufacturer determines a drug is a specialty medication, a group of specialty providers should be part of a contract promising to meet needs of drug delivery based on outcomes assessment.
3. Provide experimental but innovative contracts based on outcomes, biomarkers and financial considerations. Also, commit to a budget so that payers know their liability in advance.
For example, if a patient isn’t cured with an expensive hepatitis C medication (the cure rate is 95%), then payers shouldn’t have to pay for the drug assuming the medication was taken appropriately.
“That’s what prior authorization is all about—a budget cap,” he says. “Plans don’t really need the extra cost of doing [prior authorization]; a manufacturer has to take the risk.”
Oncology, Sullivan says, is a tougher condition to manage because of so much individualization that requires clinical flexibility. He points out that many health plans have designed treatment pathways for cancer and if members stick to the protocols, drugs will be reimbursed.
