About this study

Official title: A Phase III, Randomized, Double-Blind, Multicenter, Comparative Study to Determine the Efficacy and Safety of Cefepime-Tazobactam vs. Meropenem Followed by Optional Oral Therapy in the Treatment of Complicated Urinary Tract Infection or Acute Pyelonephritis in Adults

This is a Phase III, randomized, double-blind, multicenter, non-inferiority study to evaluate the efficacy, safety, and tolerability of FEP-TAZ vs. meropenem in the treatment of hospitalized adults with cUTI or AP.

Read the detailed description

Approximately 1004 hospitalized adult subjects (≥18 years of age) diagnosed with cUTI or AP will be enrolled in the study. The diagnosis of cUTI or AP will be based on a combination of clinical symptoms and signs plus the presence of pyuria

Subjects will be randomized in a 1:1 ratio according to an Interactive Response Technology (IRT) electronic system to receive either FEP-TAZ 4 g (2 g cefepime + 2 g tazobactam) IV every eight hours (q8h) or meropenem 1 g IV q8h. FEP-TAZ will be administered as 2 consecutive infusions of 2 g (1 g cefepime + 1 g tazobactam)

Being tested
WCK 4282 (FEP-TAZ) 4 g, Meropenem, ciprofloxacin 500 mg Optional Oral Switch, Infusion of normal saline

What is being measured

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

  1. Percentage of subjects with overall success at Day 5

    Overall success is defined as complete resolution (or return to premorbid state) of the cUTI or AP symptoms that were present at screening, except flank pain (if present), which should show at least one grade improvement and no new cUTI or AP symptoms together with microbiologic eradication of the bacterial pathogen found at study entry (reduced to <1000 colony forming units or CFU/mL)

    Measured: Day 5

  2. Percentage of subjects with overall success at Test-of-Cure

    Overall success is defined as complete resolution1 (or return to premorbid state) of the cUTI or AP symptoms that were present at Screening and no new cUTI or AP symptoms together with microbiologic eradication of the bacterial pathogen found at study entry (reduced to <1000 colony forming units or CFU/mL)

    Measured: Test Of Cure Visit (Day 17 ± 2 days)

  3. Percentage of subjects with Treatment-Emergent Adverse Events (TEAE)

    Collection of number of adverse events.

    Measured: Day 1 to the end of study Late Follow-Up visit (LFU) (26 ± 2 days)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing WCK 4282 (FEP-TAZ) 4 g, Meropenem and ciprofloxacin 500 mg Optional Oral Switch in people with Complicated Urinary Tract Infection and Acute Pyelonephritis, run by Wockhardt.

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 7 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 17 Jul 2023. Status can change between updates, so confirm with the study contact before making plans.

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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Manishkumar D Shah, PhD (91-22-26596000 ext. 6308, Manish.Shah@wockhardt.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of subjects with overall success at Day 5 (time frame: Day 5). The study lists 3 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 NCT03630081, 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 17 Jul 2023.
