The University Hospital Bonn aims to progress the investigational compound E4095372 for treatment of helminth infections in humans. For this, the University Hospital Bonn is looking for a contract research organization (CRO) to conduct GLP safety and toxicology studies in rats. The maximum treatment time will be 28 days. The entire process will be awarded to the CRO as a single-phase contract. A Master Service Agreement (MSA) or framework agreement is preferred to facilitate the commission of the required work packages in form of Statements of Work (SoWs). There will be a commercial agreement and an additional quality assurance agreement.
