Clinicians ask FDA for continued ‘discretion’ to do fecal transplants


 

Policy slow to evolve

“I’m frustrated that it’s taken over 6 years and three draft guidances to get us this far,” Christian John Lillis, executive director of the Peggy Lillis Foundation – a group dedicated to creating awareness about the dangers of C. difficile – said at the meeting.

Mr. Lillis said that probably several thousand deaths had been prevented through increased FMT access, but that it was time to create a concrete policy that advanced the therapy.

The FDA guidance issued in 2013 allowed physicians to provide FMT for recurrent or refractory C. difficile infection without filing an investigational new drug (IND) application.

Clinicians must obtain informed consent that includes a discussion of the risks, and a statement that FMT is investigational. In March 2016, the agency issued revised draft guidance that it was aiming to require stool banks to apply for INDs, as reported by Medscape Medical News.

OpenBiome has flourished under the current policy. It has provided more than 50,000 treatments to 1,200 hospitals and clinics, and has provided FMT for 49 clinical trials and for 16 single patients who received INDs, Dr. Osman said.

But requiring INDs for all centers is a bad idea, he said. “IND requirements are insurmountable for most health centers,” Dr. Osman said, noting that most of the FMT material OpenBiome produces is sent to community-based physicians.

“These requirements would likely mean restrictions in access for stool bank–provided FMT and potentially pushing patients to physician-directed FMT or discouraging physicians from using FMT at all,” he said.

Stacy Kahn, MD, FMT director at Boston Children’s Hospital in Massachusetts, said that having ready access from a stool bank was crucial.

“Universal donor FMT is much easier, much faster and much more cost effective than what we can do as clinicians,” she said.

New safety and efficacy data

One unpublished study showed that 75% of patients treated since 2011 had a sustained cure, noted Colleen Kelly, MD, a Brown University professor of medicine and principal investigator for the National Institutes of Health–funded national FMT registry (although the data in this study were not from the FMT registry).

The study, which was a collaboration between the Alpert Medical School of Brown University, Brigham and Women’s Hospital, and Indiana University School of Medicine, attempted follow-up on 533 patients; 208 were successfully contacted, and an additional 55 had died, none due to FMT.

Dr. Kelly also presented data from the FMT National Registry showing that at 1 month posttransplant, two (1%) of 253 patients had an infection possibly related to FMT; one with Bacteroides fragilis and one with enteropathogenic E. coli. Seven hospitalizations were deemed related or possibly related to FMT, including two recurrences of C. difficile.

At 6 months posttransplant, 8 (5%) of 152 patients had a serious infection, and 23 patients reported a diagnosis of a new condition, primarily diarrhea-predominant irritable bowel syndrome, which is common post FMT, said Dr. Kelly, who presented the data on behalf of AGA, which administers the registry.

The AGA supports a continuation of the enforcement discretion as a means to maintain patient access where the evidence supports the use of FMT, but the group does not back use of FMT outside medical supervision, Dr. Kelly said.
