In December 2015, Concortis Biosystems announced the integration of its product and service business into Levena Biopharma to create a unique ADC service company solely devoted to providing the antibody community with ADC tools and services from the drawing board through phase I/II clinical trials.

Concortis Biosystems’ profound expertise in the chemistry of payloads and linkers, combined with highly skilled conjugation services, has made it the provider of choice for customized ADC products. Levena Biopharma specializes in the scale up and production of high quality toxins and linker-toxins.

Following the integration, Levena Biopharma will offer a comprehensive portfolio of products and ADC services to fast-track the research and development of our clients’ ADC projects.  For more information, please inquire at info@levenabiopharma.com.
