We're your people
For more than 120 years, we’ve focused on one thing: making anti-infective medicines the world depends on – reliably, consistently, and at scale.
Builtfor continuity
For more than 120 years, we’ve focused on one thing: making anti-infective medicines the world depends on — reliably, consistently, and at scale. We build partnerships and relationships that matter.
The truth is, in this category, supply is not just operational. It’s critical.
Fermentation-based manufacturing is complex. It requires deep expertise, long-term investment, and the ability to manage uncertainty over time. The molecules cannot be rushed — and neither can the decisions behind them.
That’s why our role goes beyond production. We work with you to ensure continuity — anticipating challenges, adapting as requirements evolve, and staying aligned as the landscape shifts.
After all, we're your people.
We are your focused partner inanti-infectives
What matters is not just what we make — it’s how we support you.
Xellia is a global leader in fermentation-based non-beta-lactam anti-infectives, supplying APIs and finished dosage forms to more than 500 pharmaceutical companies across 80 countries.
This is reflected in how we work with you:
Continuity you can rely on. As one of the last Western manufacturers of several essential anti-infective APIs, we provide structurally resilient supply — with EU-based production and a long-standing track record of uninterrupted delivery.
Science that keeps you ahead
We contribute to pharmacopoeia standards, invest in R&D, and stay ahead of regulatory change — so you don’t have to catch up later.
A partnership that works in real time
We stay close to your business — anticipating needs, responding quickly, and solving issues before they escalate.

Antiobiotic Supply Chain Resilience




At Xellia, we work at the center of this challenge every day. Here is our perspective on what is at risk, why it matters, and what needs to change.

⏳ 12 days to CPHI Milano. Let's start with where we stand: we've spent years becoming the supplier procurement teams stop worrying about. Not by luck. By building redundancy, capacity and resilience into everything we do, long before you ever need it. Now here's what we're curious about. Not costs. Risks. Specifically, how you're managing them. 🔍 If your primary API supplier had one bad quarter, what actually happens to your pipeline? 🔍 Who on your team owns supply risk, and do they have real visibility, or just a report that explains it after the fact? 🔍 How many of your suppliers have you actually stress-tested, versus just listed? 🔍 How actively do you collaborate with vendors on mitigations, as opposed to just building stocks internally? Most suppliers are built to survive an audit. We're built to survive a crisis, and we've engineered our entire operation, so you don't have to. So maybe the real question isn't what a reliable partner costs. It's what you're exposed to without one. Curious? Let's talk, honestly. Booth 18A31, October 6-8. We're Xellia. We're your people. 👉 https://lnkd.in/exmi9Q7p

What do you know about Sepsis? On World Sepsis Day, it's time to stop, think and recognise that sepsis is your body's extreme, life-threatening response to infection, and it's the number one cause of death in hospitals.* Sepsis is often difficult to identify in its early stages, but there are signs that may indicate it: Slurred speech or confusion Extreme shivering or muscle pain Passing no urine all day Severe breathlessness It feels like you're going to die Skin is mottled or discoloured It's a fight we know well. The anti-infectives we make every day are part of how clinicians treat sepsis and the infections behind it, and awareness like this is part of that same work. Awareness saves lives. #CriticalMedicines #WorldSepsisDay #SepsisAwareness *All facts from the Global Sepsis Alliance: https://lnkd.in/eT3PUrhE

Sterile or non-sterile. Micronized or not. Outside API manufacturing, that sounds like a footnote. Inside it, it shapes how a process runs for as long as the product exists. Because the better the API fits the process, the less the process has to bend. Fewer additional steps. A shorter path through validation. A simpler story to tell in the dossier. Fewer variables in a product where nobody is looking for more of them. That's what the range is built to do: Polymyxin B Sulfate in sterile and non-sterile, micronized and non-micronized. Colistimethate Sodium in sterile micronized, sterile non-micronized and non-sterile grades, because different formulations don't ask the same things of an API. Bacitracin across the same breadth, supporting a range of manufacturing processes and dosage forms. The intent behind all of it is simple. You should be able to choose the API your workflow requires, ready to use. The complexity of getting there is real. We'd rather it sat on our side of the relationship. Somewhere, a patient is waiting. The API should never be what stands in the way. We're Xellia. We're your people. https://lnkd.in/esJHAYFJ

How do you build great teams? In modern matrix organisations, finding a path to success means bringing intent, determination and a shared vision to the table. Last week our Global Production, Supply & Quality team came together in Copenhagen to build on the incredible work of the last 8 months. We have seen our supply delivering on time, our production optimised, quality at consistently high levels, all while navigating the challenges of global geopolitics. Now, the team are ensuring that Xellia is driving ahead into 2030 and beyond. Of course, this doesn’t happen by accident. You need to have the clarity, conviction and connections across the functional areas to deliver a strategy that has ambition and is the living breathing embodiment of Xellia’s values. And the outcome? Ownership! Ensuring that every single priority has a name attached to it, along with a timeline means that the roadmap to continued success is visible to everyone. But it wasn’t all work and no play, in fact far from it. To keep that energy going, they cooked, sailed, and watched an eclipse (not often you can say that). Our COO, @Alexander Sproedt expresses the less tangible outcome, ‘We built strong connections while together face to face to really engage and challenge one another. Feedback is so vital to what we want to achieve in GPSQ and it came at many points, even if it was arguing about who was going to steer the boat! Proud to lead this highly motivated team.’ At Xellia the team is everything. We’re Xellia. We’re your people. Find out more at https://www.xellia.com/

Got a question about supply that's been sitting with you? Ask us. That's what CPHI is for. 🧪 This year at Milan, October 6 to 8, we're showing up a little differently. Less brochure, more conversation. Come to Booth 18A31 and we'll talk honestly about where supply is heading, what's changing in how we work, and what we've got coming that we're excited to share in person. Because the real conversations at CPHI never happen over a glossy handout. They happen when someone asks the question they've actually been thinking about, and they get a straight answer from someone who knows what they're talking about. So bring the question. We'll bring the people. Get in touch now and let's have time booked in before the diary fills up. Curious? Let's talk. We're Xellia, and we're your people. 📍 Booth 18A31 🗓️ Milan, October 6 to 8, 2026 👉 Book time with us: https://lnkd.in/esJHAYFJ #Xellia #CPHI #Pharma #AMR #Innovation
