Safety Study of Intravenous Hydrogen-Oxygen Ultrafine Bubbles in Adults

Indonesia50 participantsStarted 2026-05-01

Plain-language summary

The goal of this clinical trial is to learn whether hydrogen-oxygen ultrafine bubbles can be safely given through a vein (intravenous infusion) to adults. This is a first-in-human study, meaning this type of infusion has not been tested in people before. The study focuses on safety and does not aim to treat or prevent any disease. The main questions this study aims to answer are: 1) Can hydrogen-oxygen ultrafine bubbles be given safely without causing serious or unacceptable side effects? 2) What dose range can be given safely to adults for future research? About 40 adult participants, including healthy volunteers or people with mild, stable health conditions, will take part in the study. Each participant will receive two intravenous infusions, given one week apart. Some participants will receive a higher dose during the second infusion, depending on their assigned study group. Researchers will closely monitor participants before, during, and after each infusion. This includes checking vital signs, heart activity, and blood tests. The study will also collect exploratory laboratory measurements, such as markers related to oxygen levels and oxidative stress, to help guide the design of future studies. Participants will be followed for safety for about three weeks after starting the study. The information gained from this research will help determine whether hydrogen-oxygen ultrafine bubbles can be studied further in clinical research.

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.
