About this study

Official title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Assess the Safety and Efficacy of VP 20621 for Prevention of Recurrence of Clostridium Difficile Infection (CDI) in Adults Previously Treated for CDI

The objectives of this study are: (1) to evaluate the safety and tolerability of VP 20621 dosed orally for up to 14 days in adults previously treated for CDI; (2) to characterize the frequency and duration of stool colonization with the VP 20621 strain of C. difficile; (3) to evaluate the efficacy of VP 20621 for prevention of recurrence of CDI; and (4)to select a dose regimen of VP 20621 to be used in future studies.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)

    An adverse event (AE) is any untoward, undesired, unplanned clinical event in the form of signs, symptoms, disease, or laboratory or physiological observations occurring in a study participant, regardless of causal relationship. TEAEs were defined as all AEs that start during the study drug treatment period (and up to 7 days after the last dose of the study drug) and were not seen at baseline, or were seen at baseline but increased in frequency and/or severity during the study drug treatment period (and up to 7 days after the last dose of study drug). SAE was any AE that results in any of the following outcomes: death, a life-threatening event, inpatient hospitalization or prolongation of an existing hospitalization, a persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions, a congenital anomaly/birth defect, other medically important events based upon appropriate medical judgement.

    Measured: Baseline up to 7 days after the last dose of study drug (up to Week 3)

  2. Number of Participants With Positive Clostridium Difficile Stool Cultures Demonstrating Non-Toxigenic Clostridium Difficile-Strain M3

    Measured: After study drug administration period (14 days) through Week 6

Secondary outcomes (4)
  1. Number of Participants With Clostridium Difficile Infection (CDI) Recurrence

    CDI recurrence was defined as at least 1 event characterized by ALL of the following: >=3 unformed (loose or watery) stools within 24 hours (data derived from Diarrhea case report form (CRF) page which was to be completed for any clinical event of diarrhea or loose/watery stool occurring between Day 1 and Week 6); a positive C. difficile stool assay, or pseudomembranes on endoscopy/surgery; and no other likely cause of the diarrhea in the opinion of the investigator.

    Measured: Baseline (Day 1) up to Week 6

  2. Number of Participants With Use of Antibacterial Treatment for CDI

    Any antibacterial medication used after Day 1 for which the investigator selected the indication "antibacterial for C. difficile infection".

    Measured: Baseline (Day 1) up to Week 6

  3. Number of Participants With Clinical Events of Diarrhea or Loose/Watery Stools

    Data were derived from all AEs starting on or after Day 1 for which a Diarrhea CRF page was completed.

    Measured: Baseline (Day 1) up to Week 6

  4. Time to First CDI Recurrence

    CDI recurrence was defined as at least 1 event characterized by ALL of the following: >=3 unformed (loose or watery) stools within 24 hours (data derived from Diarrhea CRF page which was to be completed for any clinical event of diarrhea or loose/watery stool occurring between Day 1 and Week 6); a positive C. difficile stool assay, or pseudomembranes on endoscopy/surgery; and no other likely cause of the diarrhea in the opinion of the investigator. Time of onset is from date of randomization to date of first CDI recurrence. Time to first CDI recurrence was assessed using Kaplan-Meier curve. Due to small number of subjects (<50%) with CDI recurrence, median time to event was not evaluable.

    Measured: Baseline (Day 1) up to Week 6

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing VP20621 in people with Clostridium Difficile Infection, run by Shire at 59 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Jun 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 59 sites in United States, Canada, Belgium, Germany, Spain and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 12 Feb 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) (time frame: Baseline up to 7 days after the last dose of study drug (up to Week 3)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01259726, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jun 2021.
