Study summary

This is an open-label study evaluating the safety and efficacy of CP101 treatment in 1) Subjects in CDI-001 who had a CDI recurrence within 8 weeks of receiving CP101 or placebo; OR 2) adults with recurrent CDI who are eligible for direct study entry into CP101-CDI-E02. Subjects who are experiencing recurrent CDI will undergo screening procedures. Subjects who meet eligibility criteria will be eligible to be enrolled in he study and administered CP101.

Approximately 200 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.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from May 2018 to primary completion in Dec 2020, 31 months.

Results were first posted in Aug 2022, 1 year 7 months after primary completion.

Of 23 phase 2 interventional studies under Clostridium Infections, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 19 and three quarters within 39. This study's 31 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 30, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
