The notion of "added therapeutic value": a
key element of transparency
The notion of
added therapeutic value is quite simple. It has been precisely defined
by many sources, including the Declaration on Therapeutic Advance
of the International Society of Drugs Bulletins in November 2001
(1). Basically, a new medicinal product can be said to have added
therapeutic value if sound clinical data show that it offers patients
better efficacy, and/or better safety, and/or simpler administration,
than existing alternatives.
Citing the free
trade principle, the Regulation does not require medicinal products
to offer added therapeutic value in order to be authorised for sale
on the European market. All that is requested is a satisfactory
balance between efficacy and safety. As a result, many new drugs
are simply more or less equivalent to their predecessors.
Yet it is essential
for patients, health care professionals and health economists to
know whether or not a new drug offers added therapeutic value, so
that they can make rational choices among the available treatments.
The Medicines
in Europe Forum does not seek to make added therapeutic value a
criterion for granting marketing authorisation, but simply requests
that assessment reports on new medicinal products provide an analysis
of added therapeutic value based on available data. Failure to do
so is to deprive the public of useful information.
After the first
sentence of article 12-3, another sentence should be added to the
effect: " European Public Assessment Report (EPAR) conclusions
will mention available data comparing the new medicinal product
with existing treatments. It will provide a judgement on the degree
of added therapeutic value offered by the new medicinal product,
or state that comparative data are insufficient or lacking to determine
the degree of added therapeutic value."
A sentence should
also be added before the last sentence of recital 28a specifying
that: "The EPAR must nevertheless mention available comparative
data determining the place of the new medicinal product relative
to existing treatments, or, if need be, the lack of comparative
data."
