About this study

Official title: Two-Part, Single-Centre Pharmacokinetic Study of iOWH032 in Adult Male and Female Healthy Volunteers, and Adult Males With Cholera

This study will assess if the pharmacokinetics, safety and tolerability of iOWH032 are grossly different in 1) Bangladeshi healthy population and 2) Bangladeshi cholera patients. This is not a hypothesis-driven research study.

Read the detailed description

This study will be conducted in two parts.

The first part (Part A) will evaluate the pharmacokinetics, safety and tolerability of iOWH032 in healthy, adult Bangladeshi volunteers.

The second part (Part B) will evaluate the pharmacokinetics, safety and tolerability of iOWH032 in adult Bangladeshi patients with cholera. While female participants will be included in Part A, only male patients will be enrolled in Part B. The rationale for excluding women in Part B is the difficulty in separating urine from stool in severely dehydrated females with rapid rates of purging. Moreover, it has been difficult to retain adult females in the hospital after improvement of their diarrhoea because of their household responsibilities, which might impact compliance in this small study. Further, no sex differences in the pharmacokinetics of iOWH032 were found in the study conducted in healthy subjects in the US, which included 42 males and females, nor have sex differnces been observed in preclinical studies.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • iOWH032Drug

    Part A: Participants will be randomized at a 3:1 ratio to receive treatment with iOWH032 or placebo. A randomisation code will be generated. Each participant will be assigned the next participant number available and thereby will be assigned randomly. Active treatment will consist of an oral tablet containing 300 mg of iOWH032. The placebo will consist of identical looking tablets.

    Part B: There will be no randomization during this trial. All eligible patients will receive 300 mg of iOWH032.

Study groupRoleWhat they receive
Males / Females (Healthy)OtherPart A: This initial part of the study will be conducted in adult Bangladeshi healthy volunteers (4 males, 4 females) to assess the pharmacokinetics, safety, and tolerability of single doses of iOWH032. Participants will be admitted to the Clinical Trial Unit (CTU) of icddr,b (located at a 10 minute drive from the icddr,b main campus) the day prior to dosing and remain for 48 hours after dosing, unless treatment and/or follow-up of an adverse event (AE) require longer in-unit observation or treatment.
Receives: Drug: iOWH032
Males (Patient)OtherPart B: Patients will be eligible for the study if they have clinically severe dehydration and meet all other inclusion and exclusion criteria. Upon signing consent, they will be admitted to the Research Ward of the Dhaka Hospital of icddr,b.
Receives: Drug: iOWH032

What is being measured

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

  1. Calculation of concentration-time data

    For both Part A and Part B:

    • pharmacokinetic parameters
    • adverse events (AEs)
    • laboratory values
    • physical examination and vital sign findings
    • summary statistics

    For Part B, patients with culture-proven V. cholerae O1 infection will be evaluated independently of those with a negative culture. Those who are culture negative for V. cholerae but have received iOWH032 will remain in the study and the same protocol will be followed for their management including the follow up visit.

    Measured: Day 1 through end of treatment (Day 150)

Secondary outcomes (1)
  1. Measure of Adverse Events

    The safety and tolerability endpoint for this study is adverse events (AEs). All participants and patients receiving investigational product (iOWH032) will be included in the safety analysis. Laboratory values, physical examinations and vital signs will be summarized over time and treatment group using the descriptive statistics and plots.

    Measured: 7 days after receipt of the single dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing iOWH032 in people with Diarrhea and Cholera, run by PATH at 1 site in Bangladesh.

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 10 inclusion and 30 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 11 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Bangladesh. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Calculation of concentration-time data (time frame: Day 1 through end of treatment (Day 150)). 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 11 Jun 2015.
