How long is
the study?

you will be able to continue
in the second part for a total of one year.

What I have to do
during this study?

You will need to visit the study doctor
approximately every month.
Throughout the study, you will have tests done
and you will be asked questions about how you are feeling.
You will also need to give some more blood at different times during the study.

Beat OK?

Why do I have to
give some blood?

This is required to perform some tests to check
your health and to provide you
with the treatment (the study drug).


Why is that?
Why can’t I
simply take a pill?

The purpose of ATTeST is to test whether
a new way of delivering the study
drug is helping children like you.

Some blood will be taken from you,
and then the blood will undergo some laboratory
procedures and be given back to you
through a blood vessel in your arm

Do I need to be
attached to
any machine
to receive
the study drug?

No. The laboratory procedures needed to insert
the study drug in your blood are done
separately. You may play or have breakfast
and something to drink while the procedures
are done. You will come back when procedures
are completed and your blood is ready
to go back into your body.


What will happen
if I choose to be part of the study
and decide later
not to continue?

How long was
that study?

Alarm Cloud 17

Six months, but some of the children
have been in treatment since 2014.

But if the drug
was already given
to children like me,
why can’t be simply
given to me
without my participating
in the study?


There is not enough information
available now for doctors
to decide whether the study drug
is really helping children like you.
This new study is needed to collect all the information
required to come to a final decision.
Your contribution to the study might help you
and children like you in the future.
