Affimed successfully completes preclinical development of AFM 13

Heidelberg, Germany; February 08 2010: Affimed Therapeutics AG, the therapeutic TandAb antibody company, today announced the successful completion of the preclinical development of its lead product AFM 13 for the treatment of Hodgkin’s lymphoma. Following promising preclinical data the company is now preparing the start of its first clinical study with AFM 13.

Preclinical pharmacology, pharmacokinetic and toxicology data have shown strong evidence for the tolerability and efficacy of AFM 13 to treat Hodgkin’s lymphoma. Several studies with cynomolgus monkeys confirmed a good tolerability of the TandAb. No clinical toxicities were observed.

During the preclinical development of AFM 13 a robust GMP manufacturing process with a stable formulation was established. The generated clinical material is now ready for clinical development. Stability tests on the produced charges are ongoing.

AFM 13 is an innovative bispecific antibody based on the company’s proprietary TandAb technology. TandAbs are tetravalent antibodies with manifold application possibilities. In the oncology indications TandAbs bind target molecules on the surface of tumor cells and simultaneously activate T cells or natural killer cells (NK cells). TandAbs are able to identify and selectively destroy tumor cells in the human body.

Dr. Rolf H. Günther, CEO of Affimed, commented:
“This successful preclinical program adds a further important milestone to the development of our lead product and provides further validation of our technology platform. AFM 13 is the first TandAb antibody to enter clinical development from a pipeline of own preclinical TandAb candidates. The strong evidence of tolerability and efficacy in treating Hodgkin’s lymphoma will be further verified through clinical trials. IND and IMPD filings will be submitted soon.”
