"The opioid crisis in America is not over. We must remain vigilant to address this long-standing problem in new ways. Doctors need more alternatives to opioid drugs for patients suffering from chronic pain. This is how Marty Makary, commissioner of the Food and Drug Administration (Fda), the regulatory agency for drugs in the United States, justifies the new guidelines that have just been drawn up to curb the still rampant abuse of these drugs in the country. Despite the crackdown imposed in recent years on what has been declared the most serious post-war public health emergency in the US, they continue to claim victims.

Few alternatives

.

In spite of recent declines in consumption, the FDA explained in presenting the new measure, opioids remain commonly prescribed to about 1 in 5 adults in the United States living with chronic pain, as effective alternatives are limited. As part of its broader strategy to address the opioid crisis, the US agency has therefore published draft guidance entitled 'Development of non-opioid analgesics for chronic pain', aimed at accelerating safe and effective non-opioid treatments and reducing prescription-related opioid abuse.

"The FDA can help by providing clear guidance such as this, which makes regulatory pathways more predictable for innovators and drug developers, enabling effective, low-risk therapies to quickly reach the millions of Americans living with chronic pain," Makary further explains.

Serve strategy

.

The Fda's broader strategy to deal with the opioid crisis, the US agency emphasises, 'includes calling for changes to safety labelling for opioid painkillers such as OxyContin to better reflect current evidence; strengthening enforcement of regulations on the importation and sale of illegal opioid products; and facilitating the development of non-opioid alternatives'.

The latest guidelines fulfil the mandate in the Support Act that requires the FDA to issue guidelines to help address challenges in the development of non-opioid treatments for pain management. It emphasises efficient approaches to drug development, with a focus on study design, appropriate patient populations and meaningful outcomes, such as reducing the need for opioid use.

The 5 Priorities

.

There are five main regulatory demands in the draft document, on which the FDA is asking the public for feedback within 60 days of publication in the Federal Register. Here they are:

- Establishing indications for different areas (e.g. broader categories covering more chronic pain conditions than single chronic pain indications);

- Design clinical trials to ensure robust safety and efficacy assessment, including innovative trial designs and the role of mechanistic understanding of both the drug and the chronic pain conditions being treated;

- Evaluate the ability of non-opioid medications to avoid, reduce or eliminate opioid use;

- Incorporate statistical principles, patient reported results and the use of accelerated programmes to support drug development in this area.
