What is ACPS about?

and why we make a difference

ACPS (Applied Clinical Pharmacology Services) is a small-size, science-based CRO specialized in the early clinical development of new drug substances and drug products. Launched Sep-1997, ACPS originally covered the full scope of services in applied clinical pharmacology: consulting, clinical trial design & management, medical writing, teaching & training.

Since mid-2019, ACPS now mainly operates as Senior Applied Clinical Pharmacology Consultant for strategic, scientific, logistic, and regulatory challenges in early clinical development.

Pursuant to this refocus, our website is now restructured as free of charge Information Platform on Applied Clinical Pharmacology that provides support for professionals in early clinical development.


ACPS was launched in 1997 by Associate Professor Dr. med. Christian De Mey as a multi-disciplinary network of scientific, regulatory, administrative and logistic experts in Applied Clinical Pharmacology. In its earlier days, ACPS also provided full service support for clinical phase I-II trials for novel drug substances and drug products.

2019, ACPS was restructured, resized and refocused on mainly providing Applied Clinical Pharmacology Consultancy in early clinical development.


ACPS’ Central Operations are based in Wiesbaden, Germany.

2000-2017 ACPS had a permanent affiliate in Sofia, Bulgaria. In this way, ACPS contributed to the development of trial resources in Bulgaria. During these years, ACPS also collaborated closely with clinical sites in Hungary and Romania. We still call upon these sites if and as needed. We also have qualified and collaborated with various sites in other countries and regions.

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.

2022 ACPS celebrated its 25th anniversary. Time to look back. Time to look forward: at ACPS we remain dedicated to bringing 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.
