What is being measured

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

  1. POC: Difference in clinical response rate of LFF571 compared to vancomycin in patients with moderate C. difficile infections at day 12/13.

    Measured: Day 12/13

  2. POC: Safety and tolerability of LFF571

    Safety assessments will include vital signs, laboratory tests, electrocardiograms (ECG), pharmacokinetic (PK) samples and adverse events. (Cohorts 1 and 2)

    Measured: Day 12/13

  3. POC:Clinical response rates (clinical cure) of patients with moderate C. difficile infections to different LFF571 dose regimens and total daily doses (cohort 2).

    Clinical cure is resolution or improvement of symptoms and signs of C. difficile infection such that additional or alternative antimicrobial therapy or other theraperutic intervention is not needed. In addition, patient must have absence of fever for two consecutive days and <3 non-lliquid stools per day for two consecutive days

    Measured: Day 12/13

  4. Cohort 2: Clinical response rate (clinical cure) of LFF571 in patients with mild and moderate C. difficile infections to different LFF571 dose regimens and total daily doses administered orally for 10 days

    Clinical cure is resolution or improvement of symptoms and signs of C. difficile infection such that additional or alternative antimicrobial therapy or other theraperutic intervention is not needed. In addition, patient must have absence of fever for two consecutive days and <3 non-lliquid stools per day for two consecutive days.

    Measured: Day 12/13

  5. Cohort 2: Dose-response relationship of different dose regimens and total daily dose s of LFF571

    Measured: Day 12/13

  6. Cohort 2: Safety and tolerability of LFF571 dose regimens and total daily doses administered orally for 10 days to C. difficile infected patients.

    Safety assessments will include vital signs, laboratory tests, electrocardiograms (ECG), pharmacokinetic (PK) samples and adverse events.

    Measured: Day 12/13

Secondary outcomes (9)
  1. POC: To evaluate the time to resolution of diarrhea during the treatment period for LFF571-treated patients (cohorts 1 and 2)

    Measured: End of therapy

  2. POC: To evaluate the relapse rate within 30 days following completion of LFF571-treated patients (cohort 1)

    Measured: 30 days

  3. POC: To evaluate the sustained response and relapse rate within 30 days following completion of different oral LFF571 dose regimens (cohort 2)

    Measured: 30 days

  4. POC: To evaluate the fecal concentrations of LFF571 following different LFF571 dose regimens (cohort 2)

    Measured: 30 days

  5. POC: To evaluate the serum concentrations of LFF571 following different LFF571 dose regimens. (cohort 2)

    Measured: 30 days

  6. Cohort 2: Time to resolution of diarrhea during the treatment period for oral LFF571 in C. difficile infected patients.

    Measured: Day 12/13

  7. Cohort 2: Serum concentrations of oral LFF571 following different dose regimens in C. difficile infected patients.

    Measured: Day 12/13

  8. Cohort 2: Fecal concentrations of LFF571 following different oral LFF571 dose regimens in C. Difficile infected patients.

    Measured: Day 12/13

  9. Cohort 2: Sustained response (sustained clinical cure) rate and clinical relapse rate at 30 days following completion of different oral LFF571 dose regimens.

    Clinical cure is resolution or improvement of symptoms and signs of C. difficile infection such that additional or alternative antimicrobial therapy or other theraperutic intervention is not needed. In addition, patient must have absence of fever for two consecutive days and <3 non-lliquid stools per day for two consecutive days

    Measured: 30 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing LFF571 and Vancomycin (POC) in people with Moderate Clostridium Difficile Infection, run by Novartis Pharmaceuticals at 18 sites in 2 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 3 inclusion and 5 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 19 Dec 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States, Canada. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

POC: Difference in clinical response rate of LFF571 compared to vancomycin in patients with moderate C. difficile infections at day 12/13. (time frame: Day 12/13). The study lists 6 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 NCT01232595, which also lists 2 linked publications.

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 19 Dec 2020.
