General information about the trial
|
|||
Main objective of the trial |
Evaluate the tolerability of a combination therapy with Diamyd, vitamin D and etanercept
|
||
Protection of trial subjects |
To ensure subject safety a Safety Plan is in place describing the study specific safety measures that are to be taken during the study. This Safety Plan must be used in conjunction with this
protocol.
The purpose of the Safety Plan is to ensure:
the safety of patients receiving etanercept, Diamyd and vitamin D treatment in the study.
that appropriately qualified medical personnel are readily available to advise on trial related medical questions or problems regarding the study drug treatment in the above mentioned study.
that study personnel are educated about know side effects of the study drug treatment and how to handle them.
that patients and their parents/legal guardian(s) are given information about possible side effects.
