ABSTRACT Monoclonal antibody based immune checkpoint blockade therapies have achieved clinical successes in management of malignant tumors. As the first monoclonal antibody targeting immune checkpoint molecules entered into clinics, the molecular basis of ipilimumab-based anti-CTLA-4 blockade has not yet been fully understood. In the present study, we report the complex structure of ipilimumab and CTLA-4. The complex structure showed similar contributions from VH and VL of ipilimumab in binding to CTLA-4 front β-sheet strands.

  • Predictive QSAR Tools to Aid in Early Process Development of Monoclonal Antibodies
    Predictive QSAR tools to aid in early process development of monoclonal antibodies John Micael Andreas Karlberg Published work submitted to Newcastle University for the degree of Doctor of Philosophy in the School of Engineering November 2019 Abstract Monoclonal antibodies (mAbs) have become one of the fastest growing markets for diagnostic and therapeutic treatments over the last 30 years with a global sales revenue around $89 billion reported in 2017. A popular framework widely used in pharmaceutical industries for designing manufacturing processes for mAbs is Quality by Design (QbD) due to providing a structured and systematic approach in investigation and screening process parameters that might influence the product quality. However, due to the large number of product quality attributes (CQAs) and process parameters that exist in an mAb process platform, extensive investigation is needed to characterise their impact on the product quality which makes the process development costly and time consuming. There is thus an urgent need for methods and tools that can be used for early risk-based selection of critical product properties and process factors to reduce the number of potential factors that have to be investigated, thereby aiding in speeding up the process development and reduce costs. In this study, a framework for predictive model development based on Quantitative Structure- Activity Relationship (QSAR) modelling was developed to link structural features and properties of mAbs to Hydrophobic Interaction Chromatography (HIC) retention times and expressed mAb yield from HEK cells. Model development was based on a structured approach for incremental model refinement and evaluation that aided in increasing model performance until becoming acceptable in accordance to the OECD guidelines for QSAR models.

Authors: Konrad Krawczyk1*, Matthew Raybould2, Aleksandr Kovaltsuk2, Charlotte M. Deane2 1 NaturalAntibody, Hamburg, Germany 2 Oxford University Department of Statistics, Oxford, UK *Correspondence to [email protected] Abstract: Recently it has become possible to query the great diversity of natural antibody repertoires using Next Generation Sequencing (NGS). These methods are capable of producing millions of sequences in a single experiment. Here we compare Clinical Stage Therapeutic antibodies to the ~1b sequences from 60 independent sequencing studies in the Observed Antibody Space Database. Of the 242 post Phase I antibodies, we find 16 with sequence identity matches of 95% or better for both heavy and light chains. There are also 54 perfect matches to therapeutic CDR-H3 regions in the NGS outputs, suggesting a nontrivial amount of convergence between naturally observed sequences and those developed artificially. This has potential implications for both the discovery of antibody therapeutics and the legal protection of commercial antibodies. Introduction Antibodies are proteins in jawed vertebrates that recognize noxious molecules (antigens) for elimination. An organism expresses millions of diverse antibodies to increase the chances that some of them will be able to bind the foreign antigen, initiating the adaptive immune response.

    Gergely: Immunfarmakológia Immunfarmakológia Prof Gergely Péter Az immunpatológiai betegségek döntő többsége gyulladásos, és ennek következtében általában szövetpusztulással járó betegség, melyben – jelenleg – a terápia alapvetően a gyulladás csökkentésére és/vagy megszűntetésére irányul. Vannak kizárólag gyulladásgátló gyógyszereink és vannak olyanok, amelyek az immunreakció(k) bénításával (=immunszuppresszió révén) vagy emellett vezetnek a gyulladás mérsékléséhez. Mind szerkezetileg, mind hatástanilag igen sokféle csoportba oszthatók, az alábbi felosztás elsősorban didaktikus célokat szolgál. 1. Nem-szteroid gyulladásgátlók (‘nonsteroidal antiinflammatory drugs’ NSAID) 2. Kortikoszteroidok 3. Allergia-elleni szerek (antiallergikumok) 4. Sejtoszlás-gátlók (citosztatikumok) 5. Nem citosztatikus hatású immunszuppresszív szerek 6. Egyéb gyulladásgátlók és immunmoduláns szerek 7. Biológiai terápia 1. Nem-szteroid gyulladásgátlók (NSAID) Ezeket a vegyületeket, melyek őse a szalicilsav (jelenleg, mint acetilszalicilsav ‘aszpirin’ használatos), igen kiterjedten alkalmazzák a reumatológiában, az onkológiában és az orvostudomány szinte minden ágában, ahol fájdalom- és lázcsillapításra van szükség. Egyes felmérések szerint a betegek egy ötöde szed valamilyen NSAID készítményt. Szerkezetük alapján a készítményeket több csoportba sorolhatjuk: szalicilátok (pl. acetilszalicilsav) pyrazolidinek (pl. fenilbutazon) ecetsav származékok (pl. indometacin) fenoxiecetsav származékok (pl. diclofenac, aceclofenac)) oxicamok (pl. piroxicam, meloxicam) propionsav
