Public HealthAtherosclerosis Vaccine Development Receives EU Support
The atherosclerosis vaccine development program by
AFFiRiS AG is receiving financial support from the EU"s EUROTRANS-BIO call.
The respective project is being carried out in cooperation with German
company EMC microcollections GmbH. The aim of atherosclerosis vaccination is
to increase the amount of "good" high density lipoprotein cholesterol (HDLc)
in the blood and thus reduce the occurrence of harmful fatty deposits in the
arteries. Product candidates were delivered by AFFiRiS" AFFITOME® platform
technology. The target is a protein known as CETP (cholesteryl ester
transfer protein). Following vaccines for AlzheimerÂðs disease and
Parkinson"s disease, the atherosclerosis vaccine is the third such project
announced by AFFiRiS AG.
Vienna-based AFFiRiS AG today announced that its atherosclerosis vaccine
development program is receiving support from the EU"s EUROTRANS-BIO call.
The supported project - known as CETP Vaccine (ETB-2008-28) - is based on
the AFFITOME® technology of AFFiRiS AG and is being conducted together with
EMC microcollections GmbH from TÃøbingen, Germany. The urgent need for an
effective strategy against atherosclerosis is clearly evident from the
relevant figures - diseases of the cardiovascular system are the number one
cause of death in Europe and the U.S. In Europe, this is at the root of
almost 50 % of all deaths. One of the primary causes of cardiovascular
disease is atherosclerosis, a narrowing of key arteries due to fatty
deposits. Although there are options for medication-based intervention in
the form of statins, these are deemed to be of limited effectiveness despite
some notable successes.
CSO Dr. Frank Mattner explains: "Today"s therapies with Statins act on low
density lipoprotein cholesterol (LDLc) and reduce its concentration in the
blood. This type of treatment can reduce the likelihood of severe heart
disease by as little as 30 % - and that"s only if the patient takes the
necessary medication correctly and regularly. In contrast, our vaccine
approach aims at decreasing the cholesterol transfer from HDL to LDL, thus
increasing the concentration of the beneficial HDL. This vaccine approach
with its long-lasting effects should avoid patients having to take
life-long, daily medication to a strict regimen."
The main item of the joint efforts of AFFiRiS and EMC is the vaccination
against cholesteryl ester transfer protein (CETP). By transferring
cholesteryl ester from HDLc to LDLc and VLDLc, this protein reduces "good"
HDL and has a detrimental impact on the ratio of LDLc to HDLc. In the
future, our vaccine will reduce the activity of this protein and shift the
balance of HDLc and LDLc in the blood back in favour of HDLc.
Outlining the major benefit of the AFFITOME® technology, project manager Dr.
Sylvia Brunner adds: "CETP is one of the body"s own proteins. Trying to
reduce its activity using a vaccine, we are faced with a formidable
challenge. The body has many means of suppressing an immune response to its
own proteins, or limiting the effectiveness of any such response. That"s why
previous attempts to develop a vaccine against CETP failed. However, as
AFFiRiS has already demonstrated in its work on a vaccine for Alzheimer"s
disease, the AFFITOME® technology makes it possible to circumvent these
mechanisms. We are now applying this principle to atherosclerosis."
CEO Dr. Walter Schmidt continues: "So far, we have announced the development
of vaccines for three diseases - Alzheimer"s, Parkinson"s and now
atherosclerosis. Currently, four other indications are also part of our
development pipeline, all of them characterised by a very high number of
patients but also by a lack of satisfactory treatments. As a result, these
indications fit in well with our long-term strategy. Our strategy itself is
beginning to pay back as demonstrated by the licensing agreement worth EUR
430 million that we recently concluded with GSK Biologicals regarding the
rights for the technology for our Alzheimer"s vaccine programs."
The CETP Vaccine project is scheduled to last 30 months and is due to
culminate in phase I clinical trials. Overall, the support provided to the
project by the EU is worth several hundred thousand euros, while the two
project partners are bearing around half of the total costs.
