Chemotherapy and Opioid Shortages Impacting Cancer Care
/By Pat Anson, PNN Editor
Over two-thirds of cancer centers in the U.S. are reporting shortages of methotrexate and other drugs used in chemotherapy, according to a survey by the National Comprehensive Cancer Network (NCNN).
Methotrexate is a versatile drug that prevents cells from dividing. It was originally developed to treat cancer, but is also widely used to treat autoimmune and neurological conditions such as lupus, rheumatoid arthritis, migraine and multiple sclerosis.
The NCNN surveyed 27 cancer centers across the U.S. in late May, and found that 67% of them were reporting shortages of methotrexate. Most centers are also reporting chronic shortages of carboplatin and cisplatin, chemotherapy agents that are widely used in cancer treatment. The shortages have resulted in treatment delays or forced doctors to modify their treatment plans using other drugs.
"This is an unacceptable situation. We are hearing from oncologists and pharmacists across the country who have to scramble to find appropriate alternatives for treating their patients with cancer right now," Robert Carlson, MD, CEO of NCCN, said in a statement. "We were relieved by survey results that show patients are still able to get life-saving care, but it comes at a burden to our overtaxed medical facilities."
Drugs shortages in the U.S. are currently near record levels, primarily due to shipping delays and other disruptions caused by the pandemic. But the shortage in chemotherapy agents largely stems from a halt in production at a plant in India operated by Intas Pharmaceuticals. FDA inspectors found quality-control violations at the plant late last year and the agency recently slapped an import alert on the company. The agency is working with drug makers in China to make up the difference.
The FDA added methotrexate injectable solution to its drug shortage list in March. Supplies are currently limited and the shortage is not expected to end until December 2023. No shortages are currently reported for methotrexate tablets.
Hydrocodone Shortage
In addition to chemotherapy drugs, some drug makers are also reporting shortages of opioid pain medication. The American Society of Health-System Pharmacists (ASHP) recently added hydrocodone-acetaminophen combinations – commonly known under the brand names Vicodin and Norco-- to its own drug shortage database.
Generic drug makers Amneal, Camber, KVK-Tech, Major and Rhodes currently report shortages of 5 mg, 7.5 mg, and 10 mg hydrocodone tablets. None of the companies provided a reason for the shortage or an estimate for when it might end. Many of the same drug makers reported shortages of oxycodone in March.
The limited supply of opioids is also affecting cancer patients. The University of Utah Health system recently informed its drug wholesaler that it was adding 50 new beds to its cancer clinic and would be needing more pain medication to treat the extra patients.
“And the wholesaler said, ‘Well, let's just wait until we start receiving your orders to increase the amounts that you're going to buy,’” said Erin Fox, PharmD, Senior Pharmacy Director at University of Utah Health, which tracks drug shortages for the ASHP. “We're unable to be proactive. We're trying to think ahead. And we don't want to have that situation where we we're getting very close to running out or not having enough. That's basically what our wholesaler says has to happen.”
“We wish that we could fix all these things, but we don't make the medicines and we can't tell someone that they must make medicines. There are some things that are out of our control,” FDA Commissioner Robert Califf, MD, said in a recent interview with Medscape.
The Drug Enforcement Administration, in consultation with the FDA, sets the annual production quotas for opioids and other controlled substances. The DEA reduced this year’s supply of oxycodone and hydrocodone by about 5 percent, after being advised by FDA that demand for Schedule II opioids would decline. Since peaking a decade ago, DEA production quotas have fallen by 65% for oxycodone and 73% for hydrocodone.
