Are clinical trials dangerous?

All trials have risks associated with them (potential side effects etc.). While the drug has been tested for safety in pre-clinical studies, it could be the first time that it is tested in humans. Your doctor will explain all potential risks of joining the trial before you participate.

Should I take part?

Only you can decide. Some people donate money to charity but you can also make a difference by being part of a trial.

Can I volunteer?

Different types of trials have different requirements. Some trials seek healthy volunteers while others need individuals with certain diseases.


How am I protected? How is the safety of volunteers protected?

All clinical trials conducted in Singapore must be approved by their hospitals' Institutional Review Board (IRB) / Ethic Committee and/or Health Science Authority. The IRB watches each clinical trial closely and can stop a trial at any time to safeguard the participants.

What happens if something undesirable or an emergency occurs?

If you experience any unpleasant reaction or require emergency attention during the trial period, you should inform the treating doctors and contact the research team immediately.

Can I withdraw from the trial if I am uncomfortable?

Yes, all participation in trials is voluntary. However, your doctor might need to follow up with you closely after the trial for your safety, even if you have withdrawn from the study.

What are the benefits for me if I join a trial?

While you might not benefit directly from a trial, the data collected will be able to help with the development of a product to benefit the population. In most trials, lab tests are paid for.
