Shaping Tomorrow's Treatments

Getting started

Can I participate in a clinical trial?

Becoming a clinical trial participant is completely up to you. You will have many questions that your doctor, healthcare or clinical trial team can answer for you. Only you will know when you are ready to consider or participate in a clinical trial.

Anyone can consider participating in a clinical trial. You can volunteer to participate in a clinical trial if you are healthy or if you have a medical condition.

If you are healthy

You may be eligible to participate in a phase 1 study or as a control.

What to expect

For you to make the best decision about being in a clinical trial, you need to know as much as possible. Ask your healthcare or clinical trial team any and all questions you may have.

All clinical trials follow a process and are performed according to a protocol. You will:

  1. Find out about the clinical trial
  2. Meet with your doctor, healthcare and clinical trial team who will answer any questions
  3. Be provided with an informed consent form to read, understand and sign to learn the key facts about the clinical trial and what is involved if you decide to participate
  4. Determine if you can be in the clinical trial (a physical exam, lab tests, and scans might be done)
  5. Start the clinical trial when the study doctor confirms that you can participate, and you will and may undergo further examination, testing and scans, and,
  6. Complete the clinical trial (though some further follow up visits may be required).

You will not be asked to participate in a clinical trial unless your doctor, healthcare and clinical trial team think this is a good option for you to consider. The aim of clinical trials is for the benefits to be greater than the risks. By participating in a clinical trial, you may be:

  • one of the first patients to receive a life-changing treatment
  • helping future generations of patients
  • part of helping researchers better understand an illness.

When you participate in a clinical trial you are closely watched by the clinical trial team to make sure that any side effects are carefully monitored and managed, that the treatment is given the right way, and that you do your part to follow the protocol.

There can be risks and demands in a clinical trial, and below are some things you need to consider

Uncertain benefits

The treatment may not have an effect or work no better than your current treatment.

Side effects

These may range from minor and unpleasant to serious and even life threatening.

Treatment changes

You may or may not be able to continue your current treatment during the clinical trial.


You may need to go to several appointments, have more tests, or keep a daily clinical trial diary.

It’s up to you

Participating in a clinical trial is voluntary and completely up to you. When you are invited to participate (and even after you have started the clinical trial) you have the right to:

  • decide if you wish to take part or continue to take part in the clinical trial or not
  • withdraw at any time for any reason without having to provide a reason and without this affecting your medical care
  • confidentiality of your information, as any information about you or your health that is collected will be protected. It’s the law – even after you have completed or left the clinical trial.

When you are considering participation in a clinical trial, here are some questions you may wish to ask your healthcare or clinical trial team:

  • What is the purpose of the study?
  • What is the phase of the study?
  • Who is going to be in the study?
  • Will being in a clinical trial affect my medical care?
  • Why do researchers believe the new treatment being tested may be effective? Has it been tested before? How is the treatment different from the current therapies or standard of care?
  • What kinds of tests and treatments are involved?
  • What are the requirements to be part of the study? Do I qualify? What sort of tests will be done to determine if I qualify for the study?
  • What are the possible risks, side effects, and benefits of the study?
  • How will this affect my daily life?
  • How long will the clinical trial last?
  • Will I need to be in the hospital? Will the study be an in-patient or out-patient study?
  • What is the treatment schedule?
  • Who will pay for the treatment?
  • Will I be reimbursed for other expenses (for example, if I have to drive and pay for parking)?
  • How will I know that the treatment is working?
  • What happens when the clinical trial ends?
  • Will I find out the results of the clinical trial?
  • Will I be able to use the new treatment when the study is finished?
  • Will I be able to find out the results of the study?
  • Who can I talk to about the clinical trial?
  • Who can I talk to if I have any concerns about my treatment?
  • Will participating in this clinical trial prevent me from participating in other clinical trials in the future?
