7 IMMUNOGENICITY AGAINST BIOTHERAPEUTIC DRUGS Immunogenicity is well defined but is an undesirable situation in the development of biological drugs and in the treatment process. Immunity to biotherapeutics greatly affects product safety and efficacy. Especially, anti-drug antibodies (ADA) can impact drug exposure by affecting the ability of the drug to reach the intended target, alter the PK profile, and potentially mediate serious adverse effects. The clinical effects of patient who use biological drugs, immune responses are highly variable, ranging from no effect at all to extremely harmful effects (such as anaphylaxis, cytokine release syndrome, and cross-reactive neutralization of endogenous proteins mediating critical functions) on patient health. The immunogenic response generally includes both cellular (T cell) and humoral (antibody) arms of the immune response and some factors originating from the patient and the product, are affecting the immunogenicity against biological drugs. Antibodies directed against TP (antidrug antibodies, ADA) may consist of IgM, IgG, IgE, and/or IgA isotypes. An ADA response can result in a loss of efficacy and/or increase the risk of adverse reactions (e.g., infusion reactions, anaphylaxis, or immune-complex-mediated diseases). In rare cases, the ADA response is directed not only to the administrated biotherapeutic but also to its endogenous counterpart protein and may elicit a life-threatening response if the endogenous protein is unique and nonredundant and has a vital life function. In recognition of these possibilities, the regulatory agencies request that a biotherapeutic s immunogenicity be assessed and a determination of its characteristics relative to any induced clinical consequences be done as part of the approval process for biotherapeutics. Importance of Drug Tolerance Immunogenicity assays routinely utilize the therapeutic agent as a cornerstone, typically by immobilization of the drug Specificity of detected anti-drug antibodies is often confirmed by a reduction in binding of the ADA in the presence of excess soluble drug Circulating immune complexes can form when soluble residual drug is present in patient s blood The presence of soluble drug in the patient s serum sample for ADA analysis can inhibit the assay from detecting anti-drug antibodies Definition of Drug Tolerance Drug tolerance describes the sensitivity of your anti-drug antibody assay in the presence of soluble drug Tolerance is determined by assessing assay sensitivity in the presence of increasing amounts of added soluble drug Potential Effect of Antibody Response Safety Considerations Risk for hypersensitivity reactions Potential for immune complex disease 6

8 Efficacy Considerations Antibodies may bind to drug and alter the pharmacokinetics Antibodies may alter the biodistribution of the drug Antibodies may bind to (or near) the active site of a drug and inhibit its activity Antibodies may bind in a way that interferes with the drug binding to its receptor or ligand LOW IMPACT CLINICAL IMMUNOGENICITY Risk of Clinical Sequelae Binding ADA PK- altering ADA Neutralizing ADA Hypersensitivity ADA Cross-Reactive Neutralizing ADA HIGH FREQUENCY HIGH The severity of Anti Drug Antibody (ADA) impact and its frequency of occurrence have been inversely correlated. LOW SHIKARI ELISA KITS FOR DETECTING ANTI-DRUG ANTIBODIES (ADA) Matriks Biotek has produced several ADA kits for immunogenicity measurements with different formats. Strategic approach for measurement of drug level and ADA is to take samples just or -2 days prior to administrating the next drug dose where the the clearance of the drug achieved mostly. SHIKARI ELISA KITS TEST FORMATS: Screening for free antidrug antibody ELISA kit: In this test format, the plate is coated with the drug and anti-drug antibodies against this drug are captured by the drug. Same drug labeled with the enzyme and used for monitoring the ADA in the sample. Quantitative free antidrug antibody kit with confirmation: In this test format, the plate is coated with the drug and anti-drug antibodies against this drug are captured by the drug. Same drug labeled with the enzyme and used for monitoring the ADA in the sample. Quantitation is done by standard curve which are composed of decreasing amount of neutralizing monoclonal antibodies giving precise results. After measuring the ADA levels, the samples can be confirmed with a Confirmation Reagent discriminating false and true ADA in the sample. Semi quantitative DUO free and total antidrug antibody ELISA kit: Kit enables to measure free and total antidrug antibodies simultaneously within the same kit and same assay protocol. Samples either used directly to measure free ADA and/or used by first acid dissociation then after measured for total ADA. Acid dissociation disrupt circulating immune complexes and enables to detect and measure bound ADA along with free ones. Thus, ADA assay has high drug tolerance giving more information about the occurring ADA and patient status. Kit contains negative, positive and immune-complex standards enabling to control of the the assay procedure. 7

These kits are available for infliximab and adalimumab TNF alpha blockers and only from Matriks Biotek. 8

10 Biosimilars: Similar but not identical - Contract manufacturing ELISA kits for your biosimilar drug(pk&ada) A biosimilar is highly similar to, but not exactly the same as the existing, FDA-approved biologic, called the reference drug. People are familiar with generic versions of brand-name drugs, but biosimilars are not generic drugs. Generic versions of brand-name drugs are exact copies of chemically synthesized medicines. Biosimilars are not-quite-perfect copies of biologics drugs derived from living cells that are impossible to replicate exactly. Development of biosimilar proteins will present drug developers with a variety of challenges, both in manufacturing and in the clinic. Immunogenicity will prove to be one of the biggest challenges. Proper design and validation of an assay to detect anti-drug antibodies and accurate interpretation of sample analysis results will prove integral to developing a biosimilar protein. Taking the above and below-mentioned subjects into account Matriks Biotek offers to develop custom ELISA kits for your biosimilars or biologics on contract manufacturing basis depending on the molecule provided. Matriks Biotek also offers test optimizations for drug measurements in formulation buffer and in cell culture medium as well. Our drug measurement (PK) kits utilize drug target ligand (recombinant protein) for detection that makes more suitable for biosimilar drug measurements. Comparisons for measuring especially ADA and trough levels are made by the tests developed for reference drug not for biosimilar which may differ on the test results. On the contrary, we do not know the results when comparisons were done by the ELISA kit developed for the biosimilar drug, it can present low immunogenicity as well. The causes of immunogenicity can be chimeric biological drugs (e.g. infliximab), even humanized molecules (e.g. adalimumab) and fully humanized biological drugs (golimumab) most the cases the residual immunogenicity resides in the CDR regions glycosylation profiles, fermentation, purification, formulation (aggregate formation), administration mode (i.m., i.v. and s.c.), dosing, degradation products and contaminants. The pharmaceutical formulation strategy is a critical step and needs to be accurate. The knowledge about physical and biological properties of the biological drug orientate the formulation process. Important components of protein formulations are ph, stabilizer, solubilizer, buffer, and tonicity modifier (bulking agent). The typical stability problems observed in protein pharmaceuticals are non-covalent aggregation, covalent aggregation, deamidation, cyclic imide, and cleavages. This process can affect directly the efficacy (e.g. immunogenicity) and safety (e.g. adverse events) of a biological drug. The potential immunogenicity of a therapeutic protein can be influenced not only by the manufacturing processes mentioned above but also by the type of disease, route of administration and dose. Biosimilar proteins will most likely not be identical to the innovator drug, and because of this, immunogenicity becomes a major concern when developing biosimilar proteins. The potential exists for serious clinical consequences due to anti-drug immune responses with all protein therapeutics. A safe immunogenicity profile of the innovator product does not indicate that the biosimilar protein will be safe. 9

11 Why and how to test biological drugs? EXAMPLE CASE Patient: Timothy Richmond 42 years old Working in an automotive factory for 7 years. 4 years ago, I visited a gastroenterologist complaining of stomach ache, diarrhea, loss of appetite, loss of weight and fatigue and he asked me to get some tests after the physical examination. I took the tests he asked for. And based on these findings, he diagnosed me with Crohn Disease and I started therapy. I took conventional medication that he prescribed for my therapy for 3 years. At first, everything seemed okay. My complaints were gradually relieved. But, for almost a year, the clinical profile of my disease has changed. The developing of fistulas were started. My physician added the TNF blocker to the therapy protocol. I be efited from it for the first 8 months. After months 9 and 0, while I was taking it once every 8 weeks regu larly, on the week 5 after month 9, my complaints began to increase. My physician suspected it and asked me to make a blood test to measure the drug level. It was the first time that a physician asked me for such a test. It seems that these things happen when you take drugs. After taking the drug for a while, my body developed an antibody against the drug and blocked its effect. And there are kits to determine that. The physician may modify the therapy depending on the results of this test. And at the laboratory that he re ferred me to, the tests performed with the said kits revealed that my body develops antibody against the drug. My physician added another drug to the protocol to support my immune system. It has been a month now. I feel very good. And I know where to go and what to ask if I experience any problems. Physician Tim is my patient for 4 years. I diagnosed him with Crohn Disease that is an inflammatory bowel disease. I recommended conventional drugs for his therapy. For the first 3 years that I was following him, there was no problem, but when he came visiting me a year ago, his complaints were increased. I also observed the development of fistulas. The first thing that came to my mind was to add an anti-tnf blocker to the therapy protocol. We started the drug. The therapy was a success for 8 months. However, from months 9 and 0, the complaints of the patient began to increase again. I thought that his body might have developed antibody against the biological drug and asked him to take a test. The only way to find this out was to determine the antibody presence with an ELISA kit. I know a laboratory that I trust very much in these types of cases. I trust them both in terms of personnel and the kits they use. They work with Shikari ELISA Kits from the beginning. And I never saw them go wrong. I am a physician who believes in the customization of the thera pies. It is true that people differ from each other genetically and biologically. And therefore, it is natural for different diseases to have a different course in different people. Why should the therapy be the same then? It should be customized to the individual. I always discuss this in detail with each and every patient that I start to treat. If there are ups and downs during the therapy, i.e. if they do not improve even though they take drugs or they worsen after a while, they inform me. I even have patients that ask for tests with ELISA kit without me recommending it if there is something wrong. Laboratory official We can t say that there are a great number of physicians who refer their patients to our laboratory to test the antibody development against the drugs they use. But, as a matter of fact, this rationalist way is be coming a more frequent method gradually. And the reason is the patients themselves. If the patient knows that there is such a method, he warns his physician. If it is an adept and principle physician, there is no need to do that; but the knowledge and the awareness of the patient here is what determines it. We work with Shikari ELISA Kits from the beginning. Because the results of the tests performed with these kits comply very well with the clinic of the patient. * The names mentioned in this story are fictious and do not reflect real persons. 0
