Trends That Matter for Medical-Benefit Drug Spending

Posted by Peter Johnson on May 21, 2020


Spending on prescription drugs that are covered under the medical benefit increased by 65% between 2014 and 2018 for commercial insurers and 40% for Medicare, according to Magellan Rx Management's annual Medical Pharmacy Trend Report.

"The increase in medical pharmacy spend seems to largely be driven by inflation," Kristen Reimers, Magellan's senior vice president of specialty clinical solutions, tells AIS Health. "This can be a combination of two things, increasing costs of existing drugs and providers utilizing newer more expensive drugs. The pipeline was extremely robust and new therapies to market are contributing to inflation, driving the trend."
According to the report, new oncology therapies are both emblematic and a primary driver of growth in drug prices. A new generation of highly effective, biologic oncology drugs have emerged in the last decade. However, these pioneering drugs are expensive. According to the report, oncology drugs and the drugs needed to support them accounted for 43% of per-patient per-month medical pharmacy spending for commercial carriers.

Like other biologic drugs, most biologic oncology drugs have yet to see significant biosimilar competition due to barriers in the biosimilar market and development pipeline.

"The most exciting biosimilars are those currently in the oncology space. Herceptin, Avastin and Rituxan have been the top five drugs in terms of spend for the last 10 years," says Reimers. "Rituxan and Avastin now have two biosimilars on the market, and Herceptin has five marketed products. There will be competition, which will help to flatten the trend for these products, although there is still expected to be growth."
