Pressure mounts to lift FDA limits on off-label drugs

When the Food and Drug Administration gives its OK for a new drug to be sold, it specifies the diseases or conditions for which the medicine has been approved. That does not mean doctors can’t prescribe that drug for other ailments. They do. All the time. And it’s perfectly legal.

But for decades drugmakers have been barred from promoting their drugs for uses that hadn’t gone through clinical trials. Worried about safety issues, the FDA has prosecuted numerous drugmakers for illegal promotion of off-label uses and extracted billions of dollars in fines and settlements.

Those restrictions could be giving way, perhaps in part because of the appointment of Scott Gottlieb as the new FDA commissioner in May. Before his nomination, Gottlieb, a physician and a resident fellow at the conservative American Enterprise Institute, advocated loosening the restrictions on off-label communications.

That’s what Arizona did earlier this year when it became the first state to allow drugmakers to communicate directly with doctors and insurers about alternative uses of approved prescription drugs. Advocates for the loosening of the restrictions say they expect similar measures to be introduced in other state legislatures in the coming year.

These developments come on the heels of two legal cases in which federal district courts ruled that the First Amendment does not allow the FDA to prevent manufacturers from providing truthful information about their products to doctors.

Supporters say it makes sense to get rid of the restrictions on off-label drugs at a time when plenty of information and misinformation about prescription drugs is readily available to anyone with an Internet connection. And, they insist, who better to provide accurate facts about their products than their makers?

“We believe it’s a disservice to patients and physicians to prevent them from getting information from manufacturers who know their medicines best,” said Naomi Lopez Bauman, director of health-care policy at the Goldwater Institute, the libertarian think tank that devised the Arizona legislation and is promoting bills in other states.

Bauman said she expects bills to be filed elsewhere in the coming year, but she refused to disclose which states Goldwater is targeting.

Many critics, however, remain firmly opposed to such efforts. “There have literally been dozens and dozens of examples of off-label uses of drugs encouraged by pharmaceutical companies in reckless ways that have led to substantial patient morbidity and mortality,” said Aaron Kesselheim, director of the Program on Regulation, Therapeutics and Law at Harvard Medical School.

Before a new drug can be sold in the United States, the FDA must affirm that it is safe and effective for specified uses, which are then described in the medicine’s labeling. But once a drug is approved, doctors are free to prescribe it for uses not specified in the labeling. That is because the FDA regulates products but not the practice of medicine.

Prescribing for off-label uses has become common. A 2013 study found that 30 percent of the prescriptions for oncology drugs were used for off-label purposes. Another found that 70 percent of a popular category of pediatric antipsychotic drugs were prescribed for purposes not cited in the FDA’s approval of those medicines, including, for example, for the treatment of attention-deficit/hyperactivity disorder.

Sometimes the off-label use of prescription drugs comes to be consider the best treatment for certain conditions. “For some cancer drugs, the best therapeutic use is for offlabel purposes,” said Peter Pitts, president and co-founder of the Center for Medicine in the Public Interest, a nonprofit research and advocacy organization that is funded by the pharmaceutical industry.

One example is tricyclic antidepressants, a class of drugs that do not have FDA approval as treatment for nerve-related pain yet are consider to be the first choice of drugs for that purpose.

Nevertheless, a recent study published in the journal JAMA found a higher incidence of adverse drug effects from offlabel use than from on-label use.

Pitts does not think the FDA should prohibit drugmakers from dispensing information that might be relevant to those off-label uses. “In fact, it’s almost irresponsible not to let them dispense that information as long as it’s truthful, accurate and not misleading,” he said.

Pitts says it is unreasonable to expect drug manufacturers to embark on additional clinical trials to demonstrate the safety of already approved drugs for new purposes.
