WASHINGTON (AP) — Federal health officials on Monday laid out a proposal to spur development of customized treatments for patients with hard-to-treat

FILE - President Donald Trump listens as Dr. Marty Makary, commissioner of the Food and Drug Administration, speaks in the Roosevelt Room of the White House, Monday, Sept. 22, 2025, in Washington. WASHINGTON — Federal health officials on Monday laid out a proposal to spur development of customized treatments for patients with hard-to-treat diseases, including for rare genetic conditions that the pharmaceutical industry has long considered unprofitable.

The preliminary Food and Drug Administration guidelines, if implemented, would create a new pathway for bespoke therapies that have only been tested in a handful of patients due to the challenges of conducting larger studies. The FDA announcement specifically mentions gene editing, although agency officials said the new approach could also be used by other drugs and therapies. It’s a shift long sought by patients, advocates and researchers focused on rare diseases, which often do not fit within the pharmaceutical industry’s business model or the FDA’s traditional drug-approval system. “It is our priority to remove barriers and exercise regulatory flexibility to encourage scientific advances and deliver more cures and meaningful treatments for patients suffering from rare diseases,” FDA Commissioner Marty Makary said in a release. The announcement comes a week after Makary said the FDA would drop its decades-old standard of requiring two clinical trials for standard drug reviews. That was the latest in a series of changes to FDA norms and standards, many which have not gone through federal procedures traditionally used to update agency rules. Senior FDA officials said the recent changes, including the pathway proposed Monday, don’t constitute new FDA standards. The FDA will take comments on its draft guidance for 60 days, before beginning to finalize it. In recent years, academic researchers have shown they can use emerging technology to correct individual defects in a patient’s genetic code. Last year, a team at Children’s Hospital of Philadelphia and the University of Pennsylvania designed a therapy using CRISPR, the Nobel Prize-winning gene editing tool, to treat a baby born with a rare disease that causes ammonia to build up in the blood. Traditionally, the FDA requires drugmakers to demonstrate the safety and effectiveness of their experimental treatments in clinical studies that compare a set of patients getting the therapy with others taking a sham treatment or an alternative intervention. The more patients enrolled, the stronger the evidence. But for conditions that can affect a tiny fraction of people worldwide, drug companies often have little incentive to invest millions of dollars needed to complete a study and bring it through the FDA approval process, which can take a decade or longer. The pathway announced Monday would create a standardized process for authorizing experimental treatments and, importantly, offering companies the possibility of commercializing them. The FDA already authorizes the use of experimental drugs under what’s called “compassionate use,” for people with no other medical options. But the process is cumbersome to navigate and strictly prohibits companies or researchers from profiting from treatments that haven’t been vetted by the FDA. The new pathway’s name — plausible mechanism — is a reference to criteria FDA regulators will require before greenlighting any experimental therapies. FDA officials say the approach will be reserved for conditions that are well understood and where there is a plausible reason to think that the therapy will act on the underlying genetic or cellular biology of the disease. Researchers must also confirm that the therapy successfully targeted the patient’s genetic or biological abnormality.The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education and the Robert Wood Johnson Foundation.
