Cinfa Biotech is the biosimilar company of the Spanish Cinfa Group. We develop, manufacture and commercialise high-quality biosimilars. Our goal is to achieve a premier position within the global biosimilar market. We do our business on a fully integrated level, combining our specialist expertise in early- and late-stage biosimilar development and in global commercialisation of biosimilars.


Cinfa Biotech is developing high-quality biosimilars for indications in oncology and inflammatory diseases.

Our lead product candidate is B12019, a biosimilar version of Neulasta® (INN: pegfilgrastim) to treat chemotherapy-induced neutropenia. Pegfilgrastim, a granulocyte colony-stimulating factor (G-CSF) receptor agonist, is used to stimulate bone marrow to produce more neutrophils to decrease the incidence of infection in patients undergoing chemotherapy. The development program for B12019 has been successfully finalised.

During B12019 development, the GMP production process was established at commercial scale. B12019 provides a high level of comparability to Neulasta® in physico-chemical and biofunctional parameters.

The clinical development program for B12019 was based on scientific advice from EMA and included two clinical studies. Both studies were finalised successfully and demonstrated significant comparability of B12019 to Neulasta® in pharmacokinetic, pharmacodynamic, safety and immunogenicity properties.

All data confirm the biosimilarity of B12019 and Neulasta®, these data are the basis for the upcoming Marketing Authorisation Application at the EMA.
