A medicine, how is it done?

The development of new cancer drugs is a complex process that follows a series of rigorous stages and takes several years to complete. Here are the main stages:

1. Laboratory research
Discovery of the M-XX molecule
a potential drug for treating cancer
1. Laboratory research
2. Pre-clinical research
Evaluation of the M-XX molecule
in animals
2. Pre-clinical research
3. Clinical trials
Evaluation of the M-XX molecule in humans

Phase 1 : Is it safe?

Phase 2 : Are there any signs that it's working?

Phase 3 : Is it better than what already exists?
3. Clinical trials
4. Health Canada approval
Evaluation and approval
(or not) of M-XX as a new drug
4. Health Canada approval
5. Manufacturing and distribution
The new drug is now available and can be prescribed to cancer patients.

Phase 4 : What happens in the long run?
5. Manufacturing and distribution

Are you familiar with the 4 phases of clinical trials in oncology?

Phase 1 : Is it safe?

In general, only a few people with cancer are recruited. They often suffer from advanced cancer and have generally received all available treatments that can be offered. Phase 1 is used to determine whether an experimental treatment is safe for patients. More specifically, it is about finding the highest dose of treatment that can be given without serious adverse reactions. The goal might also be to:

Phase 2: Does it do what it is supposed to do?

Usually, a group of patients with the same type of cancer receives the experimental treatment.Phase 2 is to test the efficacy of the product and determine the optimal dose.In some studies, patients may be randomly assigned to different treatment groups. These groups may receive different doses or follow treatment in different ways to determine what is safest and most effective.The goal might also be to:

Phase 3: How does it compare?

Most Phase 3 clinical trials are conducted with a large number of patients who have the same type of cancer or, more rarely, with patients who have different types of cancer.Phase 3 is used to compare the experimental treatment with the treatment usually used (called “reference treatment” or “standard treatment”).Phase 3 trials are comparative trials.Most of the time, two or more groups of patients are randomized: one will receive the reference treatment and the other the experimental treatment. It is not the doctor who decides which of the treatments his/her patient will receive.Key points of Phase 3 clinical trials:

Phase 4: What happens in the long term?

Once a new treatment is approved and available to the entire population, its long-term effects are studied.

How am I protected during a clinical trial?

Many measures are in place to protect clinical trial participants. Every effort is made to minimize the risks. The following is a list of protective measures used to ensure the safety of clinical trial participants.
Good clinical practice
Good clinical practice

The research team must ensure compliance with good clinical practice during the course of the trial. These rules ensure the protection of the participants and the quality of the results of the test.

Health Canada Regulations
Health Canada Regulations

Researchers must conduct their clinical trials in accordance with the law. This includes allowing inspections to ensure compliance with regulatory requirements.

Scientific and medical surveillance
Scientific and medical surveillance

It allows to stop the test if the expected benefits are not there, or if the adverse effects are more harmful than expected.

Informed consent
Informed consent

The participant consent process includes the use of an informed consent form that clearly explains the clinical trial, benefits and anticipated risks and describes the rights and responsibilities of the participants.

Research Ethics Board
Research Ethics Board

The Research Ethics Board evaluates and authorizes clinical trials before they begin and continue until they are completed.
