We don’t just do safety — we make safety work for you
If you’re looking for a traditional toxicology or pharmacovigilance consultant, you might be in the wrong place.
At Xzencis, we look at the bigger picture: how decisions in discovery, development, and post-marketing connect — and where safety insight can unlock strategy, speed, and value.
Our work starts where conventional expertise reaches its limits: at the interfaces between science, business, and governance. We help our clients turn fragmented information into coherent strategy — aligning scientific truth with regulatory reality and commercial ambition.
Safety, when viewed systemically, is not a cost or a constraint — it’s an enabler of innovation, investment confidence, and long-term resilience. That’s why global pharma, investors, and biotech founders turn to us when they need clarity and foresight, not just another report.
Eight connected capabilities — one coherent system
Connecting insight to impact
We align non-clinical, translational, and clinical safety into one continuous strategy — interpreting the entire body of scientific and operational evidence to guide development, partnering, and investment.
Seeing the full picture
We analyze how safety, operations, and governance interact — integrating signals from multiple disciplines and real-world experience to reveal hidden feedback loops, bottlenecks, and leverage points.
From target to translation
Design and interpretation of studies that link mechanism, exposure, and clinical risk — connecting experimental findings with clinical and contextual relevance for regulatory and business decision-making.
From clinic to confidence
Integrated pharmacovigilance and signal management that connect early data with late-stage and post-market realities, ensuring that safety insight reflects both controlled trials and real-world patient experience.
Science meets investment
Independent evaluations for investors, licensors, and partners — interpreting technical, clinical, and market data togetherto translate risk into clear, value-based decisions.
Turning issues into inflection points.
Rapid assessment and resolution of complex safety or regulatory challenges — restoring momentum and confidence through integrated, cross-functional analysis rather than isolated troubleshooting.
Structures that enable, not constrain
Design of adaptive frameworks that make data flow, accountability, and decision ownership transparent — enabling evidence-based leadership across functions and geographies.
Building resilient systems
Advisory and mentorship for leaders and boards on embedding systemic intelligence — connecting scientific, organisational, and societal dimensions of safety for sustainable innovation.
They trust our expertise
We collaborate across the pharmaceutical ecosystem — from global R&D leaders to emerging biotechs and investors — helping each navigate complexity, connect disciplines, and make decisions that stand the test of reality.
Founder & Managing Director, Xzencis AB
Dr. Steffen W Ernst MD PhD MBA DABT ERT(BTS)
A physician, toxicologist, and entrepreneur, Steffen Ernst has spent nearly three decades at the intersection of science, safety, and strategy.
His career spans leadership roles in global pharmaceutical R&D, the founding of biotech ventures, and strategic advisory work across Europe and the US.
Holding an MD and PhD in Toxicology and an MBA from the Edinburgh Business School, Steffen combines deep scientific expertise with commercial and organisational insight. He has served as Vice President of Global Patient Safety at Ipsen, senior leader in Translational Safety at AstraZeneca and Pfizer, and advisor to investors and innovation agencies including the EU EUREKA and EIC programmes.
Through Xzencis, he applies systems thinking to pharmaceutical development — connecting non-clinical safety, translational medicine, and patient safety to create clarity where complexity dominates. His work emphasises that “safety is not a stand-alone discipline, but a strategic driver of innovation, value, and trust.”
Steffen is known for his optimism, integrative thinking, and a good sense of humour — qualities that make him a sought-after collaborator for leaders facing uncertain decisions in complex systems. Based in Gothenburg, Sweden, he works with clients and partners worldwide.
Our Vision
We believe that the future of drug development will belong to organisations that can think and act as systems — connecting science, safety, and strategy into one continuous flow of insight.
At Xzencis, our vision is to help create that future: a pharmaceutical ecosystem where every decision is informed by context, every function understands its interdependence, and safety is recognised not as a barrier, but as an enabler of innovation, trust, and sustainable growth.
We work for a world in which collaboration replaces fragmentation, clarity replaces noise, and systemic intelligence becomes a shared capability across industry, academia, and government.
Because when complexity is understood as connection, progress becomes not only possible — it becomes natural.
