Website update in progress

Following the transformation of Polpharma Biologics (learn more), this site will focus on biosimilars development in Switzerland. In Poland, we operate now as Rezon Bio – a contract developer and manufacturer of biologics (CDMO). More at www.rezonbio.com.

Due to the demerger of Polpharma Biologics into two independent companies (detailed information can be found in the “Knowledge center” section), the website polpharmabiologics.com is currently being updated. For details on the CDMO business, please visit the Rezon Bio website

About us

Polpharma Biologics International (PBI) builds on a strong legacy as a next-generation biosimilar company designed for speed, flexibility, and smart execution.

We don’t operate like a traditional pharma giant – and this is by design. Our lean, highly experienced team is driven by a shared purpose: making high-quality biologics accessible to more people, faster.

We work with a global network of partners while focusing our in-house expertise where it matters most: regulatory strategy, clinical development, CMC, and program leadership. From concept to commercialization, we know how to build, scale, and deliver.

Our VIBE: the way we work
Velocity. Impact. Belonging. Empowerment.

Our values shape how we think, collaborate, and deliver. They guide our decisions, strengthen our partnerships, and keep us focused on expanding access to biologic therapies that are reliable, sustainable, and built to last.

Velocity

We act with focus and urgency – making clear decisions and moving programs forward with purpose

Impact

We prioritize work that expands access and creates meaningful value for patients and healthcare systems.

Belonging

We foster trusted relationships across teams and partners, creating an environment where collaboration drives stronger outcomes.

Empowerment

We place ownership in the hands of experienced people and support them to lead with accountability and confidence.

Why we exist

Biologic medicines can change lives – but only if patients can reliably access them. Our purpose is to expand access to high-quality biologic therapies by building biosimilars designed for durability, affordability, and long-term supply.
We take responsibility beyond development – guiding biosimilars through approval, commercial production, and ongoing lifecycle management to help ensure they remain viable and available for patients over time. Through disciplined execution and a long-term mindset, we support sustainable healthcare systems and broader patient access worldwide.

Who we are

PBI is a biosimilar company focused on advancing high-quality biologic therapies from scientific insight through commercial production – and sustaining their value throughout the product lifecycle.


Operating from Zug, Switzerland, we combine experienced in-house leadership with a globally connected partner network to guide programs with clarity, accountability, and long-term commitment.

Our model is intentionally designed for focus and scalability: we retain critical capabilities internally while collaborating with trusted partners to deliver efficiently at every stage of development and supply.
Built on scientific rigor and disciplined execution, we are committed to expanding patient access to biologic medicines while supporting sustainable healthcare systems worldwide.
