Study: 2014 a record-setting year for U.S. medicines
Total spending on U.S. medicines increased 10.3% on a real per capita basis to $373.9 billion in 2014, with a record volume of 4.3 billion prescriptions filled. The year also marked the highest number of transformative medicines launched in more than a decade, according to a new report issued by the IMS Institute for Healthcare Informatics. IMS Health is a global information and technology services company based in Parsippany, N.J.
The study—Medicine Use and Spending Shifts: A Review of the Use of Medicines in the U.S. in 2014—found total dollars spent on medications in the U.S. rose 13.1% on a nominal basis last year, up from a 3.2% increase in 2013. Primary drivers include higher spending on innovative new treatment options, the lower impact of patent expiries and increases in list prices of branded medicines. The factors that came together to drive the extraordinary spending growth in 2014 are expected to have less impact in future years, resulting in more moderate levels of growth.
Much of last year’s innovation-led spending growth was from specialty medicines, which grew 26.5% and accounted for one-third of medicine spending, up from 23% of the total spend five years ago. New drugs contributed $20.3 billion to growth in 2014, including $11.3 billion from four new hepatitis C treatments as nearly 10 times as many patients were treated for that disease last year than in 2013.
The impact of patent expiries has consistently slowed spending growth over the past five years. In 2014, that impact was $11.9 billion, down significantly from the peak amount of $29.3 billion in 2012. Last year, 42 New Molecular Entities were launched—the largest number in a decade—focused on disease areas that include oncology, autoimmune disorders, hepatitis C, HIV, multiple sclerosis and diabetes. Prices for branded products last year rose at an average rate of 13.5% on an invoice basis, but were reduced to a 5%-7% increase when taking into account off-invoice discounts and rebates.
“Last year’s $43 billion growth in spending on medicines was record-setting and the result of simultaneous very high levels of spending on new drugs and an unusually low level of patent expiry impact,” said Murray Aitken, IMS Health senior vice president and executive director of the IMS Institute for Healthcare Informatics. “It also was a landmark year in the implementation of the Affordable Care Act—and yet, the increase in the number of insured patients under the ACA directly accounted for only $1 billion of the spending growth as patients took some time to ramp up their medicine use."
Spending reached $373.9 billion in 2014, up 13.1%, the highest level since 2001 when growth was 17%. In addition to the lower impact from patent expiries and the record spending on new brands, price increases for protected brands also increased spending in 2014 by $26.3 billion, contributing 8.2% to total market growth on an invoice price basis. Estimated net price growth was substantially lower, as rising off-invoice discounts and rebates offset incremental price growth and reduced the net price growth contribution to 3.1%.
Spending on specialty medicines increased $54% billion over the past five years, contributing 73% of overall medicine spending growth in that period. The biggest driver of specialty spending growth was the more than 161,000 patients who started treatment for hepatitis C in 2014, more than four times the previous peak as spending on widely adopted new treatments totaled $12.3 billion.
The drug R&D pipeline has shifted to specialty medicines over the past decade, with 42% of the late-stage pipeline now specialty—up from 33% 10 years ago. Ten therapies were launched in 2014 with Breakthrough Therapy status as designated by the FDA under the 2012 FDA Safety and Innovation Act.
Last year saw the largest number of orphan drugs launched in a single year, bringing the total number of treatments with orphan designation to 230. Cancer remains the most common orphan drug category, and nine “ultra-orphan” drugs—for populations fewer than 10,000—became available last year. Among the most anticipated innovations are biosimilars—generic versions of biologic drugs—which began being filed for FDA review in 2014 with approvals already underway this year.
