Problems issued from changing process of Epotin alfa 13 Eprex formulations With Human serum albumin (HSA) With Polysorbate 80 (Tween ) Diagnosis EPO antibody mediated PRCA cases Unexplained loss of effect (LOE) Anaemia (Hb decreases by about 0.1 g/dl/day) Low reticulocyte count (< /μl) Platelets. White blood cells : normal Bone marrow (strongly recommended) – Normal cellularity – Erythroblasts very rare (< 5 %) Positive Epo antibody test

Change in formulation 14 Immune-response and adverse reactions: PRCA case example Nicole Casadevall - EMA

Change in formulation continue 15 The interaction of Tween and the uncoated rubber in pre-filled syringes appears to cause leachates. These leachates have been implicated in causing aggregation of epoetin molecules that then enhance their antigencity.

EMA (Biosimilars) 18 First guide line 2005 Scope: In principle, the concept of similar biological medicinal product is applicable to any biological product. However, in practice, the success of such a development approach will depend on the ability to characterise the product and therefore to demonstrate the similar nature of the concerned product Reference Should be licensed in EMA

Follow-On Protein Products: Regulatory and Scientific Issues Related to Developing 21

FDA (Follow on proteins) 22

FDA (Follow on proteins) 23 The Agency indicated its intention to issue guidance documents to specifically address human growth hormone and insulin. But, as our knowledge of this issue expanded, we reconsidered our focus and determined it would be more appropriate to initially promulgate guidance that is more broadly applicable to follow-on protein products in general. We are in the process of developing such guidance with respect to products approved under the FDC Act (updated 7/2009)

Approved follow-on proteins in FDA 24 FDA (Follow on protein) Hylenex (hyaluronidase recombinant human) Hydase (hyaluronidase) Fortical (calcitonin salmon recombinant) Nasal Spray Amphadase (hyaluronidase) GlucaGen (glucagon recombinant for injection) Omnitrope (somatropin [rDNA origin])

Case Study: Omnitrope 25 Omnitrope is the first recombinant human growth hormone product approved through the abbreviated pathway, Specifically, the approval was based on the following:

FDA (Biosimilars) 26 Scope: The guidance focuses on therapeutic protein products Protein means any alpha amino acid polymer with a specific defined sequence that is greater than 40 amino acids in size. Reference: Should be licensed in US

WHO (Similar Biotherapeutic Products SBPs) Scope: Applies to well-established and well-characterized biotherapeutic products such as recombinant DNA-derived therapeutic proteins. Vaccines, plasma derived products, and their recombinant analogues are excluded from the scope Reference: 27

Health Canada (Subsequent Entry Biologic SEBs) Scope : The guidance applies to biologic drugs that contain, as their active substances, well characterized proteins derived through modern biotechnological methods such as use of recombinant DNA and/or cell culture Canadian Guidelines shares the similar concept of the WHO 28

Korean FDA (Biosimilars) Scope: Similar to EMA Concept Reference: should be a biological product authorized in Korea. Preclinical and Clinical aspects Similar to WHO 29 Scope:, well characterized proteins derived through modern biotechnological methods such as use of recombinant DNA technology Rerefence: Registrered in CDSCO (Indian) (Similar Biologic)
