Introduction
Clinical Trials are the best way to test whether a treatment is effective and better than other treatments (or no treatment).
New treatments or drugs for diseases‘ prevention, early diagnosis or cure are examined in a safe and efficient way.

As a patient, you might be considering enrolling in a clinical trial or you might be offered to by your physician.
If you are interested in the development of new treatments, you can also be proactive and increase your knowledge about clinical trials by yourself.

Introduction
Let‘s agree on words!
The process we are going to describe is more typical of new drugs development, but also applies to any other type of intervention, such as diagnostic or surgical procedure, lifestyle changes (diet, exercise, etc.) or comparison between new and existing therapies in terms of effectiveness and safety (with the opportune difference when discussing doses, placebo, etc which may not be pertinent).
From now on we will use the word “treatment” for making things easier!

Summary
What are clinical trials?
Clinical trials aims to improve existing treatments or to replace them with new and better ones.
Before a new treatment is made available for patients, it must be tested in a clinical trial for safety and efficacy.

Summary
What are clinical trials?
Clinical trials are designed for learning more about the positive and negative effects of a treatment.
Treatment‘s efficacy and safety, however, can be totally assessed only by long-term use on patients in the daily clinical practice.

Summary
What are clinical trials?
Before being tested on patients in a clinical trial, new treatments must be carefully evaluated in the laboratory.
If the results of laboratory studies of a possible treatment are promising, clinical trials can be designed to assess its effects in patients.

Summary
What are clinical trials?
Clinical trials are the only effective and safe way to test a treatment after it has been carefully evalutated by laboratory analyses.
In fact, clinical trials aim to assess not only treatments‘ efficacy but also all the possible risks.

Summary
What are clinical trials?
New treatments need to be statistically evaluated by clinical trials on very large group of similar patients (differences among patients affected by the same disease can quite big and could affect the results of the clinical trial).
Results must be systematically reviewed and carefully analysed.

Summary
Why are clinical trials important?
Clinical trials help developing new and better treatments for patients.
Assessing safety and efficacy of a new treatment is a very rigorous and long process. For this reason, new treatments usually take a lot of time before becoming available for the public.

Enrolling in a clinical trial?
Patients should be selected for a clinical trial if they are likely to benefit the the most from the new treatment.
Clinical studies give them the opportunity to get new and experimental treatments not yet available on the market.This is especially true for diseases with no-known cure.

The clinical trial process
Some clinical trials are conducted on one group of patients only, whilst others compare two groups.
Patients of different groups must be as much as possible similar e.g. they must have the same medical conditions and the same stage of the disease.

Summary
The clinical trial process
Patients are assigned to one group or another (therefore receiving the new treatment or the standard one) by a method called randomisation, i.e. the choice is made by chance through a random generator.
This type of clinical trial is called randomized trial.

Summary
The clinical trial process
When the study is conducted on two groups of patients, the first group is called “controI group“ and often receive the standard available treatment, while the other one is called “active group“ and is given the new treatment.
This type of clinical trial is called controlled trial.

Summary
The clinical trial process
The control group in a clinical trial is treated with the same care as the active group.
If possible, neither the researchers nor the patients should know which group every participant has been assigned.
This special type of randomised trial is called blinded or masked randomised trial and ensure equal treatments for both groups.

Summary
The clinical trial process
For many diseases there are no standard treatments available yet. In this case the control group receives a dummy treatment called placebo such as a sugar pill.
Important For ethical reasons, placebo control groups are not allowed if a treatment already exists and patients can benefit from it. Therefore the best standard available treatment must be used.
