Abstract:
Analytical similarity assessments typically focus on comparing the physical, chemical and functional properties of a biosimilars product to the reference product, to understand where the two products are similar and where they are not similar. An attempt is then made to justify why observed differences will or will not impact the clinical outcomes (e.g. safety, including immunogenicity, efficacy, PD or PK). The justification typically requires making a bridge between an observed difference and a clinical outcome via some type of a functional assay. This type of assessment is only as good as the assays being used (e.g. what level of difference would have to be present in order to observe a difference in the functional response). When differences are observed, new or more sensitive assays may be developed, independent of a relationship between the observed
difference and a clinical outcome. We argue that if one starts from a detail understanding of the product, clinical indications,
and safety profile of the reference product and other similar products, then one can a priori determine which physical, chemical
and functional attributes are either known to impact or likely to impact the clinical outcomes. Using this knowledge, attributes
can be identified that may require a detailed understanding of the relationship and interrelationship(s) between the attribute
and the clinical outcomes as well as between attributes and the clinical outcomes (e.g. is there a relationship between high
mannose and sialic acid levels on PK?). With this knowledge first, methods are developed, along with the appropriate controls,
that have the sensitivity required to detect meaningful differences. The assessment of fingerprint like similarity can then be
based on (1) both the full physical and chemical comparison of the product to the RPP and (2) the detailed analysis of the key
properties, with sensitive assays, that allow linkage between key product attributes and clinical outcomes. We will provide an
overview of our view on fingerprint-like similarity and how it can be applied to biosimilars development.

Abstract:
The assessment of and conditions for the interchangeability of biological and small-molecule drug products are very
different. Small-molecule drugs are well defined and can be exactly reproduced. If their products, brand-name and
generic, are declared to be bioequivalent then they are (most frequently but not always) therapeutically equivalent and can
be substituted and interchanged. In contrast, biological drugs are structurally and functionally complicated, can be only
imitated but not identically reproduced, are sensitive to various environmental and manufacturing conditions, are subject
to biological and immunological influences. Consequently, only high similarity but not equivalence can be demonstrated, in
various respects, between the marketed and new products. However, even the stated bio similarity of two products does not
enable their interchangeability in terms of switching and alternating. For this, additional conditions must be satisfied. There
has been no agreement on these conditions among the various jurisdictions. Legislation in the United States, and also FDA,
has set general principles. The European EMA has issued biosimilarity guidelines for several drug products. The latter permit
in some cases possible interchangeability even though the issue is under the judgment of the member states. It is desirable to
develop a general, scientific basis for the evaluation of interchangeability of biological drug products. Suitable study designs are
considered, an approach for the assessment of switching and alternating across multiple domains is presented, and a possible
criterion for the interchangeability of biological products is described.

Title: Evaluation of biosimilar Bevacizumab in the treatment of Indian patients with nonsmall- cell lung cancer
Time : 12:00-12:30
Biography:
Deven V Parmar is Head and Vice President, Clinical R&D, Cadila Healthcare Limited, has his expertise in clinical drug development and biosimilar development. He is a Clinical Pharmacologist by training, with 25 years of clinical research experience work across various geographies
Abstract:
Statement of the Problem: The role of bevacizumab in combination with carboplatin/paclitaxel chemotherapy has been established in patients with non-small-cell lung cancer (NSCLC). This trial was designed to evaluate the effect of Zydus biosimilar bevacizumab compared to innovator’s bevacizumab in Indian patients with NSCLC.
Methodology: A multicentre, prospective, randomized, open-label, active controlled study was carried out on 248 patients with
advanced, unresectable, recurrent or metastatic NSCLC at 28 sites across India. Patients were randomized in 2:1 (169:79) ratio to
receive intravenous infusion of 15 mg/kg of test bevacizumab or reference bevacizumab, plus paclitaxel 175 mg/m2 and carboplatin
(AUC 5 mg/mL×min) every three weeks for six cycles. Overall response rate (ORR) after treatment of 6 cycles was assessed by
using response evaluation criteria in solid tumors (RECIST 1.1). Pharmacokinetics (Cmax and AUC0-t), safety and tolerability, and
immunogenicity were also assessed.
Findings: All patients were of Asian origin and males comprised >70% of the population in both the groups. The mean age was 57±9.71
years in test bevacizumab and 58±11.35 years in reference bevacizumab. Baseline characteristics were balanced and no statistically
significant difference was observed between both the groups. The ORR was 60.82% (59 out of 97 subjects) in Bevacizumab (Zydus)
group and 58.82% (30 out of 51 subjects) responders in the reference Bevacizumab and 90% confidence interval for the difference of
overall response rate fell within the ±20% equivalence margin (-11.96, 15.97). The pharmacokinetic assessment of the In-transformed
bevacizumab after Cycle-1 data showed the 90% confidence intervals for the ratio of the Test geometric least square mean to reference
geometric least square mean within the 80.00% to 125.00% limits for Cmax (87.99%;120.41%) and AUC0-t (90.70%;122.03%). The
incidence of immunogenicity in the test product treated group was marginally lower compared to the reference drug product treated
subjects (72.16% vs. 76.47%).
Conclusion: The results demonstrated biosimilarity between Zydus bevacizumab and innovator’s bevacizumab with respect to
efficacy, tolerability and safety in Indian patients with NSCLC.

Abstract:
Over the next 10 years $71 billion in worldwide biopharmaceutical revenue may be affected by the launch of biosimilars products.Several biosimilars launches already have taken place in multiple European countries, and observations from uptake in these markets hold insight for strategic planners, both in Europe and other geographies. In countries such as the US the commercial landscape is complicated by additional uncertainties in regulatory and legal policy. In this talk we will examine the learning from prior launches and apply these insights in a decision analysis framework to aid in planning for future biosimilars introductions. In particular we will address the challenges of forecasting biosimilars uptake and innovator erosion.

Abstract:
In the battle of controlling healthcare costs, the high cost pharmaceuticals, especially biologics has become an important issue.
Successful production planning requires consideration of cost factors such as manufacturing cost, capital investment to build
new facilities or to retrofit existing ones, as well as the inventory costs. The cost attributed to the opportunity lost in selling the
product or failure to meet market demand is also considered as the inventory cost. Any unplanned downtime could severely affect the
customer service level, if facility utilization is too high. Underutilization of manufacturing facilities conversely suggests a misplaced
investment in capacity. The overexploitation approach was designed to mitigate the above described facility constrains due to its
power of combining the benefits of perfusion and fed batch processing mode with adequate elimination of facility constrains of fedbatch
bioprocessing was done. The key factors considered are: adapting to modular single use technologies for facility design; smallest
mall footprint for upstream processing saves initial investment, significantly; multiproduct facilities to be designed capable of offering
production output in kilograms per month; completely avoiding the use of conventional stainless steel bioreactors and culture revived
from single low-passage cell bank can be expanded for several months without compromising the product quality. With continuous
processing advantage while adapting an overexploitation approach, the cultured cells can be processed up to 60 passages, typically.

Abstract:
Almost one decade back the first biosimilars was launched in Europe. Now they have 15 biosimilars and all are well accepted since
high price branded biologics were tough to reach by many patients. Recently biosimilars has been endorsed everywhere in the
world starting from developing to developed countries. United States Food and Drug Administration (USFDA) approved the first
biosimilars in 2015 and currently they have 03 biosimilars which are playing pivotal role in price cutting of branded biologics. They
also have many biosimilars to be launched shortly. Australia, Canada, Africa and Asia are also aggressive with biosimilars specially
India, Korea, China made remarkable effort in biosimilars. However, considering the changes in disease pattern, increasing use of
biological drugs, huge number of population, rising health awareness, recent economic growth, success history of some biologic
companies, dependence on generic items, price sensitivity, relax regulation, growing health budget, very low production cost and
other relevant factors, Asia is an important hub for biosimilars. Therefore, this study found out the prospects of biosimilars in Asia.
