Based at Mölnlycke, near Gothenburg in Sweden, Xzencis was founded in November 2018 with the vision of developing operational and product safety as a developable, value-adding and competitive asset in the pharmaceutical industry.

Our unique expertise lays in safety strategy development, pre-clinical, clinical, and marketed-product safety problem solving, in- and outbound licensing/ Due Diligence as well as organisational design and implementation of upgraded safety systems in small and mid-sized pharmaceutical companies.

We are not confined or committed to any specific Therapy Area, type of pharmacological modulators, therapeutic concepts or life-cycle stage. We review each opportunity carefully. Should we not feel 100% comfortable, we will say so and do our best to identify the most appropriate party for the task -free of charge.
