AMSTERDAM, November 23, 2010 - Amsterdam Molecular Therapeutics (Euronext Amsterdam: AMT), a
leader in the field of human gene therapy, today announces that it has
submitted its responses to the Day 120 questions posed by the European
Medicines Agency (EMA) as part of the review process for Glybera(R), a gene
therapy for lipoprotein lipase deficiency (LPLD). As outlined in the review
timetable, EMA will restart evaluation on Friday, 26th November, which
represents Day 121.

The Day 120 questions are posed following the initial review
of the Glybera registration dossier, which was submitted in December 2009.
AMT expects to receive, at Day 180, a further list of questions summarizing
the outstanding items following the EMA's review of the responses to the Day
120 questions.

The EMA formal review of Glybera is being conducted via the
centralized procedure, which is the standard route for all advanced
therapies. During 2011, AMT expects to provide updates on the results from
its follow-up and ongoing clinical studies with Glybera, in accordance with
reporting regulations.
