Nonclinical Drug Development Services and Toxicology Consultancy

Experimental Toxicology Services (ETS) Nederland BV, based in Zutphen, the Netherlands, is an independent, privately-owned company that provides nonclinical drug development services. The company is managed by Henk Tennekes, Ph.D, a highly experienced consultant in toxicology.

Non-clinical study monitoring for the pharmaceutical and agrochemical industries

ETS was established in Switzerland in 1992 and has provided nonclinical drug development services to many leading companies in the pharmaceutical and agrochemical industry. Henk Tennekes provides high quality study monitoring services for outsourced (non-clinical) studies in close collaboration with the study sponsor, usually R&D departments of pharmaceutical and biotech companies.

Reports and toxicology summaries for regulatory submissions

Henk Tennekes also prepares expert reports and toxicology summaries of non-clinical studies as part of nonclinical drug development services for regulatory submissions. In-sourcing and staff training courses can be organised by Henk Tennekes upon consultation.

Henk Tennekes has frequently been requested to provide nonclinical drug development services when a client’s internal resources were considered to be insufficient or temporarily overstretched.

Nonclinical drug development services

Nonclinical drug development services include contract research organisation (CRO) selection, study design and protocol review of non-clinical studies, study monitoring, and data analysis and review of draft and final reports.

Study monitoring by Henk Tennekes ensures that pivotal non-clinical studies on the critical path are in safe hands; Henk Tennekes has successfully managed the general toxicology department of a major European contract research laboratory (RCC, Research and Consulting Company in Itingen, Switzerland) from 1986 to 1992.
