What is ACPS about?

and why we make a difference

ACPS (Applied Clinical Pharmacology Services) is a small-size, science-based CRO that provides customised services for the early clinical development of new drug substances and drug products: consulting, clinical trial design & management, medical writing, teaching & training.


ACPS was launched in 1997 by Dr. med. habil. Christian de Mey as a multi-disciplinary network of scientific, regulatory, administrative and logistic experts in Applied Clinical Pharmacology.


ACPS’ Central Operations are based in Wiesbaden, Germany.

2000-2017 ACPS also had a permanent affiliate in Sofia, Bulgaria. In this way, ACPS contributed to the development of outstanding trial resources in Bulgaria. These are now called upon if and as needed. In this way we confirm our commitment to place our trials at the best suited sites in the best suited region.


ACPS does not operate its own research clinics, but has established dedicated alliances with well-qualified study clinics in Western-, Eastern- and South-eastern-EU. Since recently, ACPS is exploring several outstanding opportunities to develop similar alliances in the Pacific region. In this way we can propose well-qualified study Sites and Investigators that best suit the specific requirements of our Sponsors.

What makes us different

There are of course many CROs that provide similar services, but ACPS makes a tangible difference on several accounts:
Experts at your service

Each ACPS‘ project is headed by an experienced senior scientist from A to Z and projects are not downgraded to „heads-down“ project management once they are acquired.


ACPS does not favour nor does it have prejudice against using study facilities in specific regions, but it strongly advocates a competent western involvement to achieve the best possible outcome when using lower-cost, non-western opportunities.

Happy to be small

We are a small organisation with lean structures and therefore (still) can say „no“ if we consider a proposal to be unethical or scientifically invalid.

Accepting the challenge

We do not claim to know everything, but learn quickly and accept the challenge of any new technique or concept.


We maintain excellent working relationships with many regulatory agencies. We do not claim to have „friends“ at any agency to speed our applications through, but we advise our Sponsors how to optimise submissions in order to avoid delays and misunderstandings.

Fair but not 'cheap'

We operate with highly transparent cost structures. We do not try to tempt our Sponsors with apparently low fixed costs and then overcharging them with excessive pass-through costs.

Christian De Mey

CEO & Founder

Born and raised in Antwerp, Belgium, I completed my medical training and training in Internal Medicine at Antwerp University (RUCA & UIA).

Since 1984 I reside in Germany where I completed my training in Clinical Pharmacology (J. W. Goethe University, Frankfurt).

Since 1981 I work in applied clinical pharmacology and drug development: first in Industry (Squibb, Smith Kline & French), then in Contract Research (ZekaPha, IPHAR) and now at ACPS (Applied Clinical Pharmacology Services), which I founded in 1997 here in Mainz-Kastel/ Wiesbaden.

2017 ACPS celebrated its 20th anniversary. Time to look back. Time to look forward. Looking forward meant adjusting our focus.

Accordingly, we redesigned our homepage to reach out with a clear message:
At ACPS we are dedicated to bring clinical pharmacology “to the point…” i.e. to make it work in a way that matters.

This is not just a business; this is about being a dedicated professional who likes what he does (passionately) and is not yet tired of the many exciting challenges this involves.
