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

Let’s build something together

At Polpharma Biologics, we believe in the power of partnerships to unlock new possibilities in biosimilars. We collaborate with visionary companies — from global pharma leaders to innovative suppliers — to accelerate development, scale smarter, and expand access to life-changing biologics around the world.

Our approach to partnering

At Polpharma Biologics Switzerland AG , collaboration is in our DNA. As a fast-moving team building the next generation of biosimilars, we value transparency, agility, and shared ambition. Whether it’s bringing a molecule to market or streamlining supply chains, we believe in partnerships that create real-world impact.

We’re particularly interested in partners who want to co-create go-to-market strategies, contribute to tech transfer, or support our clinical ambitions across the US, Europe, and emerging markets.
