Phase 1b Ascending Dose Study of PanChol in Healthy Volunteers
Zambia32 participantsStarted 2025-10-01
Plain-language summary
Cholera is a serious diarrheal disease that can be fatal within hours of onset. The current available cholera vaccines to prevent the disease are not very effective. Panchol is a new oral cholera vaccine that may be an improvement over the currently available vaccines in use. The goal of this study is to learn safety of this new oral cholera vaccine and the body's immune response to the vaccine.
The researchers will compare the PanChol vaccine to placebo to see the side effects experienced in participants.
The participants will be adults aged between 18 and 55 years and they will be required to:
1. Be admitted to hospital until they stop passing the cholera vaccine in their stool. During admission, all side effects will be recorded by the researchers.
2. After discharge, the participants will visit the research site every month for 3 months with an optional visit at the 4th month for the researchers to assess the participants' general health.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
