DICATO TNFa (2) TNFa inhibits induction of erythroid differentiation inhibits expression of erythroid specific genes: y-globin and EpoR affects induced transcription factor GATA-1 Blocks binding of GATA-1 to its DNA sequence Conclusion: TNFa acts at several levels of the regulation of erythroid genes, in particular GATA- 1. Inhibition of GATA-1 correlates to increased NF-kB activity M.Dicato, L. Plawny, M. Diederich: Ann. Oncol. 2010, Fig. 3 – Pathophysiology of anemia. Tumor cells act on erythrocytes through macrophages by cytokine release, which leads to impaired erythropoiesis. Released cytokines can affect BFU-E and CFU-E proliferation, iron utilization and Epo production. TNFa can also affect erythrocyte half-life.

National Comprehensive Cancer Network® 2010; Practice guidelines in oncology V.2.2010 Biosimilars Biosimilars (1) For regulatory EMA to be approved: • Active substance as suc h and in the marketed form • Preclinical toxicity and pharmacology • Pharmacodynamic and pharmacokinetic activities in man • Clinical activity and toxicity in phase III Biosimilars (2) Requirements by EMA • Phase I • Phase III • Follow-on for 12 months of treated patients for possible immunogenicity Table 2: Biosimilar Development requirement Biosimilar Comparator Quality-Manufacturing: Demonstration of product quality Quality-Manufacturing Demonstration of product quality and similarity with the original product Préclinical Préclinical Pharmacodynamics (PD): in vitro & in vivo tests. Pharmacodynamics (PD): in vitro & in vivo tests. Toxicology: Repeated dose studies and local tolerance Toxicology: repeated studies and local tolerance Clinical Clinical Pharmacokinetics (PK) & PD Equivalence PK & PD equivalence vs original product Phase II dose-response No dose-response Phase III study of effectiveness in each indication Security at least 12 months (immunogenicity) Phase III comparative study of efficacy in an indication (if same mode of action for other indications Duration and cost Security at least 12 months (immunogenicity) Duration and cost 5-10 years 3 - 5 years 30 to 50 millions euros Approximately one hundred million euros NB: A comparator has 20 years of patent protection and 10 years of "data Exclusivity" therefore a monopoly position for 10 to 15 years before a biosimilar can be registered.

Dicato Edit., Targeted Oncology, Springer UK 2011 Generic Substitution • Highly effective: In USA each 1% increase in generic prescribing reduces drug cost by 1.32 billion $ annually. • In UK average cost of a generic is ¼ of the original brand drug • In generic substitution of the top 10 prescribed drugs in E.U. could release savings of 20-48% to reinvest in improved patient care Biosimilar Substitution • • • • • Biologic drug sales in US in 2010: >60 billion $ At present in Oncology in EU: G-CSF and Epo Oncology McAb in 2015 Darbepoietin in 2016 Cost savings: average 20-30% THANK YOU
