Zinplava is a CDI antitoxin B indicated to prevent recurrence in adults at high risk for recurrence of CDI3

Despite treatment with antibiotics for CDI…

The risk of CDI recurrence remains a cause for concern1,2

Epidemiologic data from the US has shown that...

People who are at risk for CDI recurrence include

  • Age ≥65 years4–6
  • History of CDI in the past 6 months5–7
  • Recent antibiotic use6,8
  • Immunocompromised9
  • Severe CDI10
  • Inadequate immune response to toxins6,11

CDI antibiotics may not be enough to reduce the risk of CDI recurrence for high-risk patients8,12

  • While CDI antibiotics may target bacteria and resolve the infection, they may also perpetuate disruption of the gut microbiota and increase the risk for CDI recurrence due to persistent vegetative C difficile and germination of remaining spores.

An inadequate immune response to C difficile toxins is a contributing factor to CDI recurrence13

Role of the body’s adaptive immune response to C difficile toxins6

  • Most patients have an adequate immune response and are able to create antibodies against CDI toxins, which limits damage to the gut epithelium and helps prevent CDI recurrence.6
    • However, some patients are unable to mount an adequate immune response to toxins, which contributes to the recurrence risk.6

ZINPLAVA: CDI antitoxin B that may prevent recurrence in adults at high risk for recurrence of CDI3

Now, you have an option to prevent CDI recurrence in high-risk patients

Non-antibiotic mechanism of action targets toxin B3,14

  • ZINPLAVA is a selective, fully human monoclonal antibody that binds with high affinity to toxin B.3

ZINPLAVA enhances the immune response against toxin B3

  • Neutralizes toxin B activity.
