The U.S. Food and Drug Administration is shutting down a pain management program that helped supply fentanyl medication to patients suffering from severe cancer pain.

In a notice published on the FDA’s website for its Transmucosal Immediate-Release Fentanyl Medicines (TIRF) program, the agency said that all TIRF medications “will be discontinued” on September 30.

The program was created due to the risks associated with fentanyl, a synthetic opioid 100 times more potent than morphine. The FDA has required a Risk Evaluation and Mitigation Strategy (REMS) for TIRF medications since 2011.

“Patients currently enrolled in the TIRF REMS may continue their TIRF therapy while supplies remain,” the FDA notice states. “Prescribers currently certified in the TIRF REMS may continue to prescribe TIRF therapy for their currently enrolled patients while supplies remain but must begin working with their patients to transition to other non-TIRF treatments.”

TIRF-REMS has also stopped accepting new applications from patients, prescribers, pharmacies and wholesale drug distributors. According to the FDA, 4,722 patients received a TIRF medication in 2017, but there are currently fewer than 150 patients getting them.

Illicit fentanyl is a notorious street drug that is involved in about 70% of fatal U.S. overdoses. But prescribed fentanyl has long been an essential medicine for patients suffering from surgical pain, breakthrough pain and cancer-related pain. It is also prescribed “off-label” for other types of severe pain.

The FDA’s decision to end TIRF-REMS came after Cephalon, which is owned by Teva Pharmaceuticals, notified the agency in August that it was discontinuing production of Actiq, a fentanyl lozenge, and Fentora, a fentanyl buccal tablet. Both medications are absorbed into the bloodstream quickly through the mouth to provide immediate pain relief.  

(Update: On September 16, FDA published a brief statement confirming that TIRF medications are being discontinued, but said the TIRF-REMS program would continue operating while supplies last.

“The TIRF REMS will remain in place as long as the manufacturers’ new drug applications or abbreviated new drug applications are approved, regardless of the marketing status of the products,” the agency said. “FDA did not request this discontinuation. It is important to note that FDA does not manufacture medicine and cannot require a pharmaceutical company to make a medicine, make more of a medicine, or change the distribution of a medicine.”

Teva did not respond to requests for comment about the discontinuations. Actiq and Fentora are expensive medications. A supply of 30 Actiq 400 mcg lozenges costs about $3,500, while 28 tablets of Fentora 100 mcg will cost about $2,300.

“I had very few patients on these medications in the past, since no health insurers would actually pay for them,” said Chad Kollas, MD, a palliative care physician and pain policy expert. “I think it’s problematic that the TIRF-REMS website isn’t offering recommendations for an effective alternative approach for the patients currently using TIRF products.”

Opioid litigation and the risk of further liability may have influenced Teva’s decision to discontinue TIRF medication. The company agreed to pay $4.24 billion to settle allegations that it illegally marketed opioids and failed to prevent their diversion.

Last year, Teva discontinued production of immediate release oxycodone as part of a strategic shift away from less profitable generic drugs.
