New Hope for Those Suffering with C. difficile Infection, a Potentially Deadly and Contagious Illness

Sponsored by Ferring Pharmaceuticals

Every year, about half a million Americans suffer from a serious and potentially deadly infection called Clostridioides difficile (C. diff) infection.1,2 C. diff infection takes hold in the gut microbiome and people who suffer from the infection may experience debilitating symptoms, including diarrhea, fever, stomach pain, and inflammation of the colon.1 Up to three in ten people who get a C. diff infection will get it again.3,4,5,6 This is called a recurrence. After that first recurrence, up to six in ten people may get another C. diff infection.3,4

The U.S. Food and Drug Administration (FDA) recently approved REBYOTA (fecal microbiota, live – jslm), the only FDA-approved microbiome-based treatment to prevent recurrent C. diff infection, after you’ve taken antibiotics for recurrent C. diff infection. The treatment, produced by Ferring Pharmaceuticals, is a liquid mix of up to trillions of live microbes.7

“Having recurrent C. diff was the scariest thing that has ever happened in my life,” remembers Patricia, a C. diff infection patient. “I’d never felt that sick before. To not be able to care for my children, to just be so weak and not want to leave the house, and then for it to go away and come back again, and then again – I lived my life in terror.”

While C. diff infection can affect anyone, older adults and people with a weakened immune system are more susceptible.1 About 80 percent of recurrent C. diff infection patients wind up in the hospital for treatment each time, causing considerable healthcare, emotional and financial burdens for patients and their families.5,8

“Until now, patients had few treatment options to help treat the devastating cycle of recurrent C. diff infections. The infection interrupts patients’ lives, keeping them at home or in the hospital, and away from loved ones,” says Dr. Paul Feuerstadt, a professor at the Yale University School of Medicine. “This new treatment option will bring hope to thousands of people experiencing this disease.”

For Patricia, this breakthrough couldn’t come fast enough. She was referred by her doctor to a GI specialist to participate in a clinical trial for Ferring’s investigational therapy.

“I wasn’t scared, because the alternative of continuing to have C. diff, and living my life where one week out of the month I was unable to care for my kids or to leave my house was even scarier,” she says. “Since my treatment more than three years ago, I haven’t had a recurrence. I was so emotional to be able to finally hug my girls again after lying on the couch and isolating myself from them for so long. We were all excited.”

In clinical trials, REBYOTA was well-tolerated with generally expected and manageable side effects. Side effects were mostly mild to moderate in severity and the most common side effects were stomach pain, diarrhea, bloating, gas and nausea.
