When the gut microbiome is in ruin,

GO BEYOND ANTIBIOTICS TO PREVENT RECURRENT C. DIFFICLE INFECTION

and restore hope with REBYOTA®

REBYOTA is the first and only single-dose FDA-approved Fecal Microbiota Transplant for the prevention of recurrent C. difficile infection1,2,a

aIn the pivotal phase 3 trial, 32.8% of patients were treated at first recurrence of C. diff infection (CDI) following antibiotic treatment of CDI.1

ANTIBIOTICS ALONE MAY NOT BE ENOUGH TO PREVENT A CDI RECURRENCE

40% to 65% of patients with rCDI may experience a subsequent recurrence.1,3

Antibiotics are the standard of care for CDI, but they don’t address the underlying microbiome disruption that leads to subsequent recurrence.4

  • Antibiotics can disrupt the gut microbiome and suppress beneficial bacteria4,5
  • CDI is associated with reduced microbiome species richness6

REBYOTA is the only FDA-approved therapy that provides trillions of live Bacteroides and Firmicutes to help restore a healthy gut microbiome and prevent a CDI recurrence.1,7,8

REBYOTA is administered directly where it is needed—the gut microbiome.

Bacteroidetes (of which Bacteroides are an important group) and Firmicutes9:

  • Are essential to the gut microbiome and work symbiotically to maintain biodiversity and gut health
  • Encourage proper immune function and resistance to C. diff

One dose of REBYOTA provides1:

15 BILLION TO
7.5 TRILLION
colony-forming units (CFU)
of live fecal microbes

The mechanism of action of REBYOTA has not been established.1 It is believed that Fecal Microbiota Transplant affects repopulation and restoration of the composition and diversity of the gut microbiome. It suppresses C. diff overgrowth and prevents recurrence.10

UPTO 65%

of recurrent C. diff patients may experience a subsequent recurrence. REBYOTA is an important preventative measure to help stop C. diff from coming back.8,9

FREDA, 70s

Freda, age 70 image

“I just knew that if I had C. diff again,
I wasn’t going to survive. But my C. diff didn’t
come back after I had REBYOTA.”

Watch Freda’s story

FREDA, age 70s

Actual PUNCH™ CD3 Trial Patient. Freda was compensated for her time. Individual results may vary.

Freda loves traveling to visit family, spending time with her husband on their farm, and caring for their bees and chickens.

She was hospitalized for severe
CDI symptoms—several days after she received antibiotics for a toothache.

After 4 severe recurrences, she and her husband feared for her life.

Most common adverse reactions include abdominal pain (8.9%), diarrhea (7.2%), abdominal distention (3.9%), flatulence (3.3%), and nausea (3.3%).1

C. difficile presentation and recurrences

  • Experienced 4 recurrences in 6 months​
  • 6 months of diarrhea, 25-lb weight loss, weakness, and exhaustion​

Freda’s journey

  • Admitted for 5 days and given antibiotics after initial CDI diagnosis
  • Received antibiotics after each subsequent recurrence. Symptoms would improve but kept returning
  • Isolated from husband
  • Enrolled in the PUNCH™ CD3 trial and received REBYOTA within 72 hours of completing antibiotics
  • No recurrences since administration in 2019

IMPORTANT SAFETY INFORMATION

INDICATION

REBYOTA (fecal microbiota, live – jslm) is indicated for the prevention of recurrence of Clostridioides difficile infection (CDI) in individuals 18 years of age and older, following antibiotic treatment for recurrent CDI.
Limitation of Use
REBYOTA is not indicated for treatment of CDI.

IMPORTANT SAFETY INFORMATION

Contraindications
Do not administer REBYOTA to individuals with a history of a severe allergic reaction (eg, anaphylaxis) to any of the known product components.
Warnings and Precautions
Transmissible infectious agents

Because REBYOTA is manufactured from human fecal matter, it may carry a risk of transmitting infectious agents. Any infection suspected by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Ferring Pharmaceuticals Inc.
Management of acute allergic reactions
Appropriate medical treatment must be immediately available in the event an acute anaphylactic reaction occurs following administration of REBYOTA.
Potential presence of food allergens
REBYOTA is manufactured from human fecal material and may contain food allergens. The potential for REBYOTA to cause adverse reactions due to food allergens is unknown.
Adverse Reactions
The most commonly reported (≥3%) adverse reactions occurring in adults following a single dose of REBYOTA were abdominal pain (8.9%), diarrhea (7.2%), abdominal distention (3.9%), flatulence (3.3%), and nausea (3.3%).
Use in Specific Populations
Pediatric Use
Safety and efficacy of REBYOTA in patients below 18 years of age have not been established.
Geriatric Use
Of the 978 adults who received REBYOTA, 48.8% were 65 years of age and over (n=477), and 25.7% were 75 years of age and over (n=251). Data from clinical studies of REBYOTA are not sufficient to determine if adults 65 years of age and older respond differently than younger adults.
