Recepton is a newly founded biotech company focused on cancer immunotherapy, the process of mobilizing the immune system to kill cancer.

In particular, we have designed:

  • a novel service platform composed of a broad portfolio of the recombinant immune checkpoint receptors. The platform can be used for rapid typing and testing of new types of inhibitors for the immunoreceptors, especially for the signaling pathway of the programmed cell death protein 1 (PD-1) and its ligand, protein PD-L1.
  • protein engineering platform for the development of multifunctional therapeutic fusion proteins
  • chemistry synthetic and biophysical methods of rational drug design, cell-based assays, preclinical studies that aim at developing new types of small-molecule inhibitors for the immune checkpoint blockade (ICB).

Recepton is continuously building a team of energetic people with scientific passion, who will work on development of innovative solutions in the field of cancer immunotherapy.

Recepton is divided into specialized scientific laboratories:

Protein Engineering Laboratory (Gdańsk)

  • Molecular biology
  • Cell line development
  • Protein production
  • Protein purification
  • Protein analytics
  • Cell based assays

Drug Discovery Laboratory (Kraków)

  • In silico modelling
  • Organic Chemistry
  • HT drug screening methods
  • NMR

Dr Tomasz Sitar
CEO, Head of Protein Engineering Laboratory

Co-founder of Recepton, Doctor in Natural Sciences at the Technische Universität Muenchen, Germany, under the academic supervision of Professor Robert Huber, the Nobel Prize winner in Chemistry. Dr Sitar has over 17 years of research and development experience in both academic and pharma/biotech organisations. Tomasz Sitar worked in the NMR Spectroscopy group of Prof. Tad Holak at the Max Planck Institute of Biochemistry between 2003 and 2011. Prior to Recepton, since 2012 he served as the R&D Senior Scientist, Cell Line Development Expert and Bioprocess Development Key Expert in Polpharma Biologics, Gdansk, Poland. Currently, Tomasz Sitar holds positions of Chief Executive Officer and Head of Protein Engineering in Recepton Sp. z o.o.

Prof. Dr. Tad Holak
CSO, Head of Drug Discovery Laboratory

Co-founder of Recepton, professor in biochemistry, a world-recognized scientist involved in biochemical research for 40 years, leading international teams of experts (including 4 years at Yale University, USA, and 25 years at the Max Planck Institute for Biochemistry in Martinsried, Germany). Results of his teams’ work were implemented in business, leading to significant progress in science and social welfare improvement by increased efficiency of diseases’ treatment. Between 1988 and 2011 Professor Holak was the leader of a research group at the Max Planck Institute for Biochemistry having about 20 R&D projects under his direction. Prior to Recepton, in 2012-2017, he has been the head of the Chemical Biology and Drug Design group at the Chemistry Faculty and at the Małopolska Biotechnology Centre of the Jagiellonian University, Krakow, Poland. At that time, he has successfully conducted number of projects financed by the National Science Centre of Poland, the Foundation for Polish Science and EU funds.
