My name is Magnus
Ingelman-Sundberg.
I work at the Karolinska
Institute in Stockholm, Sweden.
I will tell you
about some updates
in the area of pharmacogenomics.

We know that drug response and
toxicity is highly variable.
Differential drug
response is common and
only 50%-75% of patients
respond adequately
to medications.
It's dangerous because wrong
medication procedure can cause
adverse drug reactions
and they account for
about 7% of all
hospitalizations.
If one considers elderly people
of more than 70 years of age,
20% of all hospitalizations
are caused by adverse
drug reactions.
In the EU, we count about
190,000 deaths each year due
to adverse drug reactions.
The adverse drug
reactions are expensive.
It accounts for 5%-10% of
annual hospital costs.
In the US, equivalent
to about $80 billion.
Also, the individual differences
in drug response is a major
hurdle for drug development
so 32% of novel medications
are affected by safety events
after the clinical trials
have been terminated.
This is because
the Phase 3 trials
encompass maybe
2,000-5,000 patients,
whereas on the market,
the drug is exposed to
millions of people,
and they have unique
characteristics
which makes them susceptible
for certain drugs.
