HWI group – services for active ingredients,
medicinal products and medical devices

The HWI group offers a broad range of individual and specialised pharmaceutical services for the pharma, biotech and medtech sector, particularly for active ingredients, medicinal products and medical devices. Benefit from our long-standing experience in laboratory services, reference standard services, vigilance and quality services, API assessment and drug development as well as regulatory affairs services.



HWI Campus in Ruelzheim

Pharmaceutical companies, service providers and partners of HWI can register at the HWI Campus in Ruelzheim and flexibly make use of all HWI group services. Particularly pharmaceutical companies from non-EU countries.

The HWI Campus also offers innovative services: from a one-stop shop and technology platforms to AI-based service solutions.


AIQNET— Medical data ecosystem

HWI is part of a consortium that is one of the winners of the AI Innovation Competition by the Federal Ministry for Economic Affairs and Energy in 2019.
A digital ecosystem called AIQNET is being built collaboratively. The aim of the platform is to structure and use medical and clinical data in compliance with legal and ethical framework conditions.

As of January 1st, 2021, Dr Frank Böttcher will be appointed to the management team of HWI pharma services GmbH and will strengthen the current management team of Dr Stefan Wissel and Dr Melanie Kerst.

Innovation and Technology Support

Innovative Screening and Technology Platform

The vast majority of new chemical and biological active pharmaceutical ingredients (API) are poorly soluble in water and physiological media. These active ingredients are difficult for the body to take up and are therefore poorly available at their target site in the body.

HWI plans to establish an innovative screening and technology platform for the fast, flexible and cost-effective development and manufacturing of parenteral (sterile) drug formulations with poorly soluble APIs. We therefore want to further develop nanotechnology for the improvement of bioavailability.

An application for funding for this project was submitted to the Innovation and Technology Support Programme (InnoTop) of the ISB Rhineland-Palatinate. This project will be supported by funding from the European Regional Development Fund (ERDF).
