The majority of new projects originate within the Development Department. It is here that we develop innovative solutions implemented to optimize the processes of mammalian and insect cell culture development, as well as the purification processes of obtained recombinant proteins. We are responsible for key activities related to the development, qualification, and transfer of quantitative and qualitative analysis methods, both necessary during the process development stage and for the characterization of the final product. We also conduct clinical studies from the planning stage to the analysis of pharmacokinetics, pharmacodynamics, and immunogenicity of drugs administered to patients.

Within the scope of the department’s work, we focus on the design and obtaining of expression systems, as well as the derivation of stable cell lines for the production of biological drugs, including biosimilars, and the development and optimization of protein purification methods.

We deal with the transfer and characterization of protein manufacturing processes. We replicate the manufacturing process on a laboratory scale to verify the impact of various factors on the final product quality, starting from cell culture and ending with product purification. We also actively participate in scaling up the manufacturing process.

In order to continuously and reliably monitor the progress of the conducted processes and the quality of the resulting products, even at early stages of development, we develop, qualify, and validate analytical biological and physicochemical methods. A wide range of analytical methods is also utilized for the characterization of protein products and in similarity studies for biosimilar molecules.

We ensure the highest quality of all the aforementioned activities through a team with extensive expertise and by consulting proposed solutions with EMA and FDA regulatory authorities.

Another distinguishing feature is our experienced team of clinical analysts, focusing on developing demanding and unique analytical methods. These allow us to characterize key drug parameters such as pharmacokinetics, pharmacodynamics or immunogenicity using innovative analytical techniques and equipment – all within GLP-certified laboratories.

We are also directly involved not only in verifying the workflow at clinical sites, but also actively participate in the entire process, which includes:

  • Designing the clinical trial and consulting its strategy with the EMA/FDA,
  • Creating the study protocol,
  • Clinical trial start-up, overseeing and monitoring the work of clinical sites and CROs,
