About us

Your partner in contract production and development using the End-to-End business model.

We are a European biotechnological company developing therapeutic recombinant proteins including monoclonal antibodies and vaccines. Shape your future with us!

Our history

Our history starts with a merger. The company was established in 2007 and comprised of four European pharmaceutical companies:

  • Celon Pharma,
  • Polfarmex,
  • IBSS Biomed and Genexo (currently owned by Twiti Investments),
  • BioCentrum and Biotech Consulting (these entities perform scientific research in biotechnology).

We are the precursor of the biotechnology sector in Central Europe, which provided us with a unique opportunity to set the foundations and standards for the industry in the heart of Europe. We started in a small laboratory in central Poland, and today, we work in two fully equipped, modern facilities: Research&Development Centre and Research&Production Centre.

We specialize in the production of sterile biotechnological products in a manufacturing plant that meets the requirements of Good Manufacturing Practice (GMP). We are committed to integrate and commercialize scientific achievements in order to develop a biological medicinal substance based on mammalian cell cultures.

From the very beginning of our activity, we have participated in innovative projects by combining scientific knowledge and advanced technology to develop products and processes. We provide our business partners with the best biotechnological solutions, and we give the patients access to the next generation of therapeutics. For years, we have been offering outstanding specialists from all over Europe the opportunity to develop their expertise in the biotechnology sector.
