What is a clinical trial?
A study to determine whether a new treatment, drug, device, or diagnostic or therapeutic technique will help prevent, detect or treat a disease by being applied to humans.
Clinical trials also help to find out whether or not these new treatments are safe and whether they are better than treatments that are currently available.

The entire process for the commercialisation of a new medicine takes about 10 years. During that time, the number of subjects/trials gradually increases.
Phases of a clinical trial
The development of new drugs goes through a process called clinical trials: research aimed at finding new drugs for the prevention and treatment of diseases, including cancer, as well as new diagnostic and surgical techniques.
After the pre-clinical phase (in order to obtain new chemical substances and experimenting with animals in the laboratory) and before marketing the drug, researchers test its efficacy, check its safety and analyse its results in comparison with those of previously available drugs.
Trials that compare the treatment under investigation with the established therapy are called “double-blind”. Neither the participants nor the researchers know who is receiving which treatment. This ensures objectivity.

- PHASE I
- PHASE II
- PHASE III
Tolerance and safety
This is the first step in human drug research. It is usually done on healthy volunteers, or patients when it comes to anti-cancer drugs, i.e. drugs that prevent or slow down cell division and are used in the treatment of cancer. They give us preliminary information on the safety and tolerability of these drugs.
Comparison of efficacy and safety with standard treatments
The sample size is extended to thousands of patients. Numerous researchers are involved to assess the efficacy of the new medicine. Adverse effects are analysed. The new drug is compared with standard treatment to confirm evidence of efficacy. This phase takes place prior to the authorisation and marketing of a drug.
Marketing and new indications
The drug is already on the market. Testing is carried out to monitor the long-term safety of the medicine and to analyse the results on the disease itself. New indications or dosages of the product are studied and compared with other known medicines.

How to participate
Patients always sign an informed consent form stating that they agree to participate in the trial and that they have been given all the relevant information.
Patients are free to decide whether or not to participate in a clinical trial; they may only join one and they can leave at any time if they wish.
Clinical trials are regulated by law and require the approval of both the hospital’s Board and the Ethics Committee.

Scientific studies
These are research projects that aim to evaluate a certain aspect or factor of a drug that affects the treatment of a group of patients.
The aim of these studies is to answer questions after observing the effects of authorised drugs or standard treatments in patients, taking into account their genetic characteristics.
