PRISM-EXT: An Open-Label Extension of CP101 Trials Evaluating Oral Full-Spectrum Microbiota™ (CP101) in Subjects With Recurrence of Clostridium Difficile Infection

This is an open-label extension of CDI-001 (subsequently referred to as PRISM 3), and is
evaluating the safety and efficacy in reducing recurrence of CDI in adults who had a CDI
recurrence within 8 weeks of receiving CP101 or placebo in PRISM 3. Subjects who are
experiencing recurrent CDI will undergo screening procedures. Subjects who meet eligibility
criteria will be eligible to be enrolled in the extension study and administered CP101.

Approximately 70 subjects will receive CP101. The treatment duration will be 1 day. Subjects
will be monitored for recurrence of CDI, safety, and tolerability for 24 weeks following
receipt of CP101. The primary efficacy and safety endpoints will be evaluated at 8 weeks post
treatment, and all subjects will continue to be followed for an additional 16 weeks for
safety and recurrence of CDI.
