its about phases of clinical trials

2. Introduction
Controlled clinical trials are the best
way to test whether a treatment is
better than other treatments (or no
treatment).
Interventions for preventing or
treating health problems are
examined in a safe and efficient way.

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

4. Introduction
This tutorial will familiarize you
with the most important facts
about clinical trials.
We hope it will answer many of
the questions you may have
about them.

5. Introduction
Let‘s agree on words!
The process we are going to describe is
typical of new drug development, but also
applies to any other type of intervention,
such as diagnostic strategies, surgical
procedures, lifestyle changes (diet,
exercise, etc.) or comparisons between
new and existing therapies in terms of
effectiveness and safety.
To make things easier, we will use the
word “treatment” to refer to any type of
intervention.

6. What are controlled
clinical trials?

7. What are clinical trials?
Controlled clinical trials aim 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 controlled clinical trials
for efficacy and safety.

8. What are clinical trials?
Controlled clinical trials are
designed to help us learn
more about the positive and
negative effects of treatments.
A treatment‘s efficacy and
safety can only be fully
assessed after long-term use
on patients in everyday clinical
practice.

9. What are clinical trials?
Before new drug treatments
are tested in patients in clinical
trials they must be carefully
evaluated in laboratories.
If the results of laboratory
studies of a possible treatment
are promising, clinical trials
are designed to assess its
possible beneficial and
adverse effects in patients

10. What are clinical trials?
New treatments need to be
evaluated statistically in clinical
trials involving large numbers of
similar patients.
Results must be reviewed
systematically and carefully
analysed.

11. What are clinical trials?
Controlled clinical trials conducted
on large numbers of patients are
essential for assessing the efficacy
and safety of new treatments.
True False

12. What are clinical trials?
Controlled clinical trials conducted
on large numbers of patients are
essential for assessing the efficacy
and safety of new treatments.
True False
Your choice is
correct!

13. What are clinical trials?
Controlled clinical trials conducted
on large numbers of patients are
essential for assessing the efficacy
and safety of new treatments.
True False
Your choice is
not correct!

14. What are clinical trials?
New treatments that have
been tested in a laboratory
have no risks whatsoever
when used in clinical trials.
True False

15. What are clinical trials?
New treatments that have
been tested in a laboratory
have no risks whatsoever
when used in clinical trials.
True False
Correct! Laboratory tests help
designing new treatments but cannot
reveal risks for patients.

16. What are clinical trials?
New treatments that have
been tested in a laboratory
have no risks whatsoever
when used in clinical trials.
True False
Wrong!
New treatments can always
have unknown and
unpredictable risks.

17. Why are controlled
clinical trials
important?

18. Why are clinical trials important?
Controlled clinical trials help to
develop new and better
treatments for patients.
Assessing efficacy and safety of
a new treatment is a very
rigorous and often long process.
For this reason, new treatments
usually take a lot of time before
becoming publicly available.
