A new study suggests that cost-sharing policies in the US create a barrier to the treatment of chronic myeloid leukemia (CML).
Researchers examined Medicare claims data and found that “Part D” (prescription drug plan) co-insurance policies for “specialty drugs” seem to be reducing or delaying the use of tyrosine kinase inhibitors (TKIs) in patients with CML.
The team reported these findings in the American Journal of Managed Care.
“High out-of-pocket costs for specialty drugs appear to pose a very real barrier to treatment,” said study author Jalpa A. Doshi, PhD, of the Perelman School of Medicine at the University of Pennsylvania in Philadelphia.
While there is no standard definition for specialty drugs, the term typically refers to medications requiring special handling, administration, or monitoring. Most are aimed at treating chronic or life-threatening diseases.
Although specialty drugs typically tend to offer significant medical advances over non-specialty drugs, they are correspondingly more expensive. In 2014, such drugs accounted for less than 1% of prescriptions in the US but nearly a third of total prescription spending.
While insurers have been imposing higher cost-sharing requirements as part of their efforts to manage specialty drug spending, there has been limited information about the corresponding impact on patients.
“[I]t was particularly important to examine the extent to which the aggressive cost-sharing policies for specialty drugs seen under Medicare Part D, which are increasingly making their way into the private insurance market, adversely impact access to these treatments even for a condition like cancer,” Dr Doshi said.
So she and her colleagues examined the impact of specialty drug cost-sharing under the Medicare Part D prescription drug benefit on patients with CML. The team analyzed Medicare data on patients who were newly diagnosed with CML to examine whether and how quickly they initiated TKI treatment.
The researchers compared patients who were eligible for low-income subsidies and therefore faced nominal out-of-pocket costs to patients who faced average out-of-pocket costs of $2600 or more for their first 30-day TKI prescription fill.
Results showed that patients in the high-cost group were significantly less likely than the low-cost group to have a Part D claim for a TKI prescription within 6 months of their CML diagnosis. The rates were 45.3% and 66.9%, respectively (P<0.001).
Patients in the high cost-sharing group also took twice as long, on average, to initiate TKI treatment. The mean time to fill a TKI prescription was 50.9 days in the high-cost group and 23.7 days in the low-cost group (P<0.001).
“Medicare Part D was created to increase access to prescription drug treatment among beneficiaries, but our data suggest that current policies are interfering with that goal when it comes to specialty drugs,” Dr Doshi said.
She added that making Part D out-of-pocket costs more consistent and limiting them to more reasonable sums would help mitigate this negative impact.
Dr Doshi and her colleagues are now pursuing further studies of the impact of Part D cost-sharing policies in different disease areas. They hope to gain a better understanding of changes in drug access and of the long-range clinical outcomes and costs associated with any delays or interruptions in treatment.
“We need to know if the current aggressive cost-sharing arrangements have adverse long-term impacts on health and perhaps, paradoxically, increase overall spending due to complications of poorly controlled disease,” Dr Doshi said.
