REBYOTA is the first and only single-dose microbiota-based live biotherapeutic approved to prevent recurrence of C. difficile infection starting at first recurrence1,2,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
REBYOTA WAS STUDIED IN ~1000 PATIENTS ACROSS 5 CLINICAL TRIALS1,3-7,b

- Participants across 5 trials were not excluded if they had a history of food allergies1
bIn PUNCH™ CD2 and PUNCH™ CD3, participants were excluded if they had a known history of refractory CDI, IBD, IBS, chronic diarrhea, celiac disease, colostomy, active colitis, required antibiotic therapy for another condition, or had a history of fecal matter transplant.1,3,6 PUNCH™ CD3-OLS did not exclude individuals with celiac disease, IBD, IBS, and chronic diarrhea.7
PIVOTAL PUNCH™ CD3 TRIAL
Enrolled 320 patients with documented recurrent CDI (≥1 recurrence after a primary episode of CDIc or ≥2 episodes of severe CDI resulting in hospitalization within the last year).1,6
Investigator’s choice: Diagnostic test(s) used and selection of antibiotic to address active infection.6,d
Polymerase chain reaction (PCR) was utilized in >70% of PUNCH™ CD3 participants to diagnose qualified CDI.6
No bowel prep/laxatives: Patients did not receive bowel prep or laxatives prior to REBYOTA® treatment.6


cPatients also must have completed >1 round of standard of care (SoC) antibiotic therapy.6
dCDI diagnosis confirmed 30 days before study enrollment via PCR, enzyme immunoassay, glutamate dehydrogenase, toxin A or B presence, or other CDI diagnostic test. Antibiotics (vancomycin, vancomycin in combination, fidaxomicin, or other) administered ≥10 consecutive days before washout.6

REBYOTA SAFETY
FOLLOW-UP RANGED FROM 6 MONTHS TO 2 YEARS
Across the 5 trials in the clinical program, 978 patients had at least 1 dose of REBYOTA.1
In the PUNCH™ CD3 trial…
Adverse reactions reported by ≥3% of REBYOTA recipients (and at a rate greater than that reported by placebo recipients) within 8 weeks after receipt of REBYOTA or placebo.1,6,h
ADVERSE REACTIONS, n (%)1 | REBYOTA n=180 |
Placebo n=87 |
---|---|---|
Abdominal pain | 16 (8.9%) | 6 (6.9%) |
Diarrhea | 13 (7.2%) | 3 (3.4%) |
Abdominal distension | 7 (3.9%) | 2 (2.3%) |
Flatulence | 6 (3.3%) | 0 |
Nausea | 6 (3.3%) | 1 (1.1%) |
Most adverse reactions occurred during the first 2 weeks after administration1
- Proportion of patients with adverse reactions declined in subsequent 2-week intervals thereafter
- Beyond 2 weeks after administration only a few single events were reported
Most adverse drug reactions were mild to moderate in severity1
- No life-threatening adverse reaction related to REBYOTA was reported
hAdverse reactions were defined as solicited and unsolicited adverse events that were assessed as definitely, possibly, or probably related to administration by the study investigator and that occurred within 8 weeks after blinded REBYOTA or placebo administration or until recurrence of CDI.1

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.
