About this study

Official title: Phase 2A Open-label Study to Evaluate Safety, Tolerability, and Antimicrobial Activity of Single, Daily Doses of SQ109 in Urea Breath Test Positive Volunteers

Helicobacter pylori infection of the gastric epithelium is the most common bacterial infection worldwide. Its global prevalence is estimated at 50%, though the burden falls disproportionately on the developing world, where the prevalence in some areas is 80%. H. pylori infection is generally acquired during childhood, and without specific antibiotic treatment can persist for life. The infection is generally clinically asymptomatic during childhood, and even in adulthood 80-90% of infected individuals will remain asymptomatic (although they may transmit the bacteria).

SQ109 is a new, small molecule antibiotic with characteristics that make it particularly attractive to evaluate against H. pylori. In brief, SQ109 is orally bioavailable, acid-stable, has in vitro activity against H. pylori and achieves high intracellular concentration (which may be important to effect bacterial eradication).

Based on the antimicrobial activity and clinical safety, SQ109 will be evaluated in this clinical trial to assess safety and antimicrobial activity in adults infected with H. pylori. Data from this study will help determine whether larger safety and efficacy studies in individuals with H. pylori-associated duodenal ulcer disease are warranted.

Read the detailed description

A total of 30 Urea Breath Test (UBT)-Positive volunteers will be enrolled. Each subject will receive SQ109 150 mg bid with PPI or 300 mg qd by mouth daily for 14 consecutive days.

Major Inclusion/Exclusion Criteria:

  1. Subject must be 18 to 45 years of age (inclusive).
  2. Subject must have 2 positive Urea Breath Tests (UBT) obtaining during screening, and no other clinically significant disease (i.e., hematology, clinical chemistry and urinalysis tests must be within study-defined ranges. Clinical tests must be performed within 14 days of receiving first dose of study drug.
  3. Body Mass Index (BMI) must be between 18 and 33 kg/m2 inclusive.
  4. Subject must be able to give voluntary written informed consent before any study related procedure is performed.

Objectives:

  1. To determine the safety and tolerability of SQ109 administered daily for 14 consecutive days in male and female Urea Breath Test (UBT)-positive subjects.
  2. To assess antimicrobial activity against H. pylori of SQ109 administered daily for 14 days in UBT-positive subjects.

Design: Each subject will undergo screening evaluations within 14 days of study entry (Day 1) and baseline evaluations Day -14 and Day -2 to Day 1 (up to 14 days prior to the first dose). On Day 1 (first day of dosing), the subject will be administered study drug and undergo the Day 1 procedures. Throughout the 14 days of treatment phase of the study each subject will be assessed daily for adverse events (AEs). Laboratory safety evaluations will be performed on Day 7, 8, 9, or 10, and on Day 14, and Day 21. On Days 1, 4, 7, 10, 14, 21, and 28 each subject will have a UBT. On Follow-up Days 21 and 28 each subject will return to the study unit to have safety assessments.

Outcome Measures:

Safety and tolerability will be evaluated by a review of physical examinations, neurological examinations, vital signs assessments, 12-lead ECGs, routine clinical laboratory tests (including chemistry and hematology data), and AE assessments.

Efficacy Outcome Measures consist of serial UBT assessments for evidence of H. pylori in the gastrointestinal tract collected at baseline, during the 14 days of SQ109 administration, and during the 14 day follow-up period.

What is being measured

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

  1. Activity of SQ109 against H. pylori measured by Urea Breath Test Results

    In addition to assessment of safety and tolerability of SQ109, Preliminary efficacy will be assessed by serial Urea Breath Tests during the 14 days of drug administration, and recurrence will be assessed during the 14 days following the last dose of study drug.

    Measured: During the 14 days of drug adminstration and 14 days of follow-up

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing SQ109 in people with Helicobacter Pylori Infection, run by Sequella, Inc..

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

Who may be eligible to take part?

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: withdrawn, as of the sponsor's last update on 17 Nov 2015. 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 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 was withdrawn before enrolling participants, so there are no results.

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?

Activity of SQ109 against H. pylori measured by Urea Breath Test Results (time frame: During the 14 days of drug adminstration and 14 days of follow-up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Nov 2015.
