De, Lama Valderrama Noelia Milagros. "Development of new mass spectrometry methods for the characterization of protein impurities in therapeutic antibodies". Electronic Thesis or Diss., Strasbourg, 2025. http://www.theses.fr/2025STRAF008.
Texto completoHost cell proteins (HCPs) are unwanted by-products in the production of monoclonal antibodies (mAbs), and even at low levels, they can affect the safety, efficacy, and stability of biopharmaceuticals. While ELISA is widely used for HCP detection, it lacks full impurity coverage. This work explores complementary mass spectrometry-based methods to address these limitations. An immune-capture MS approach targets non-immunoreactive HCPs missed by ELISA, while advanced LC-MS/MS workflows using peptide standards enable more accurate and flexible quantification. These tools aim to improve impurity profiling and strengthen quality control in mAb manufacturing

Texto completoMonoclonal antibodies (mAbs) are highly complex glycoproteins having a lot of micro-heterogeneities which can influence their effectiveness. As a consequence, it is necessary to develop robust analytical methods, sensitive and specific to characterize them with high accuracy. The purpose of this thesis was to develop analytical methods allowing the multi-level characterization of monoclonal antibody (cetuximab), and antibody drug conjugates (brentuximab vedotin), using on-online or off-line capillary electrophoresis – mass spectrometry coupling. In the first section, a middle-up proteomic approach of cetuximab was carried out using Off-line CZE-UV/MALDI-MS coupling to separate and to characterize Fc/2 and F(ab)’2 charge variants. A top-down characterization of Fc/2 fragments was also employed. Then a new strategy off-line CZE-UV/nanoESI-MS was used to allow the characterization of this partially digest mAbs. Finally, an online coupling by CESI-MS was developed to allow the fast and accurate analysis of middle-up cetuximab. In a second part, the combination of intact, middle-up and bottom-up proteomic carried out on CZE-UV/nanoESI-MS and CESI coupling allowed the most exhaustive characterization of brentuximab vedotin. This methodology allowed the analyze of DAR, the identification of fragments drug conjugates, the simultaneous characterization of the complete structure of antibody, a significant number of post-translational modifications, all peptides drug conjugates and the identification of diagnostic ions

Thesis, Normandie, 2020. http://www.theses.fr/2020NORMR021.
Texto completoCurrently, monoclonal antibodies represent the major class of recombinant proteins used for therapeutical applications in humans. The constraints due to the production of these monoclonal antibodies in mammalian cells led scientists to develop alternative expression system for the production of monoclonal antibodies. Recently, microalgae have been shown to be able to produce functional monoclonal antibodies. However, the engineering of the N-glycosylation pathway in these microalgae is required in order to optimize the effector functions of the algae-made antibody for some therapeutic applications. In this context, this PhD thesis focused on the study of the N-glycosylation of the diatom Phaeodactylum tricornutum. Initially, we focused on the structural analysis of the oligosaccharide precursor synthesized in the endoplasmic reticulum. The results showed that P.tricornutum synthesizes a truncated precursor as compared to the other eukaryotes. Then, I have investigated the detailed structure of the oligomannosidic N-glycans and demonstrated that the Man9GlcNAc2 and Man5GlcNAc2 synthesized were similar to those found in mammals. In addition, the Man5GlcNAc2 synthesized is the acceptor isomer for the N-cetylglucosaminyltransferase I (GnT I) which initiates in eukaryotes the synthesis of complex-type N-glycans. Humanization of the N-glycosylation pathway was finally iinitiated by over-expression of the GnT I in the diatom in order to increase the amounts of complex N-glycans carrying N-acetylglucosamine residues in the terminal position

Texto completoThe quantification in plasma of monoclonal antibodies (mAbs) is an essential prerequisite to any PK/PD preclinical and clinical study. To date, reference techniques used to quantify mAbs, rely on enzyme-linked immunosorbent assay (ELISA) but the difficulties encountered in particular when the analysis focuses on the mAbs whose pharmacological target is circulating, suggest that mass spectrometry would be an interesting alternative. Applied to bevacizumab, the quantification developed strategy involves tandem mass spectrometry (HPLC-ESI-QqQ) used in MRM mode and focuses on the analysis of specific peptides bevacizumab obtained after tryptic proteolysis. Absolute quantification is achieved through calibration curve obtained from peak area ratios of bevacizumab surrogate peptide and internal standard. To propose a reference quantification methodology, we have identified the key points of development for transposition to other mAbs and compared the two most commonly used internal calibration approaches: one using protein analogue and the other a stable isotope labeled surrogate peptide (SIL-peptide). Through this development, the proposed strategy has a universal character with respect to IgG monoclonal antibodies subclasses which is based on sample processing purification using protein A followed by concentration by ultra filtration and whose quantification involves the internal calibration approach SIL-peptide. Validated according to FDA guidelines, our method shows the expected analytical performance in terms of sensitivity, specificity and repeatability for application in clinical studies
Husson, Gauthier. "Development of host cell protein impurities quantification methods by mass spectrometry to control the quality of biopharmaceuticals". Thesis, Strasbourg, 2017. http://www.theses.fr/2017STRAF066/document.
Texto completoRecent instrumental developments in mass spectrometry, notably in terms of scan speed and resolution, allowed the emergence of “data independent acquisition” (DIA) approach. This approach promises to combine the strengths of both shotgun and targeted proteomics, but today DIA data analysis remains challenging. The objective of my PhD was to develop innovative mass spectrometry approaches, and in particular to improve DIA data analysis. Moreover, we developed an original Top 3-ID-DIA approach, allowing both a global profiling of host cell proteins (HCP) and an absolute quantification of key HCP in monoclonal antibodies samples, within a single analysis. This method is ready to be transferred to industry, and could provide a real time support for mAb manufacturing process development, as well as for product purity assessment

Texto completoMonoclonal antibodies (mAbs) are therapeutic biomolecules employed as treatment against cancer and other pathologies. These glycoproteins are subject to numerous micro-heterogeneities which cou Id affect treatment efficiency. Hence, mAbs variants analysis requires powerful, rapid and accurate analytical methods to elucidate their structure. ln this thesis, works have been done to develop methods leaning on a capillary electrophoresis - mass spectrometry coupling (CE-MS) to get a multi-level mAbs isoforms analysis. First, method assessment and validation of glycosylation forms analysis by CE-MS have been done to characterize and set up a relative quantitation of these modifications. ln order to avoid potential artifactual modifications due to the sample preparation process, higher order analyses have been performed at tougher analytical levels. For that purpose, methods involving partial and total enzymatic digestion have been developed and optimized to assess the plenty of post-translational modification linked to the protein structure. Finally, whole protein analyses have been completed to get a more accurate illustration from variants heterogeneity of the medication administered. The comprehensive analysis of mAbs and their variants should help to guide the manufacturing process and go a step further in treatment optimization

Texto completoManufacturing and manipulation of therapeutic monoclonal antibodies (mAb) in the hospital before administration to patient is prone to induce their physical degradations (e.g., denaturation, aggregation). This may impact their efficacy and safety. To study the stability of mAbs, capillary zone electrophoresis (CZE) and size exclusion chromatography (SEC), coupled to native mass spectrometry (MS) have been developed. CZE-native MS method using a triple-layer coating was developed to detect and separate different conformational states (unfolded monomer, dimer) of Infliximab in a single analysis. In-depth study with digested infliximab confirmed that dimer formation was related to the Fab fragment. We also focused on covalent coatings in order to find the more adapted coating to analyze mAbs by CZE-UV and CZE-MS. We also developed for SEC a simultaneous coupling with MS and a fluorescence detector to detect the degraded mAbs. We have identified the biases inducing conformational changes (e.g. dimerization, denaturation) that may arise during native MS. We also successfully characterized aggregates and denatured monomer in stressed Trastuzumab sample. In addition, the orthogonal method SEC-ion mobility-MS has been employed to separate and measure the denatured monomers compared to their related native conformations. Moreover, the developed system enables the detection of a very low levels of degraded mAbs in infusion bags. It allows to define the critical parameters to be controlled during the reconstitution and manipulation of therapeutic mAbs in hospital

Texto completoAs toxinas imunológicas (TIs), que consistem em anticorpos conjugados com toxinas, foram propostas como tratamento para câncer e infecções crônicas. Para desenvolver e melhorar as TI, diferentes toxinas, como a ricina, foram usadas, visando uma maior eficácia contra células alvo. A toxina pulchellina, isolada da planta de Abrus Pulchellus, tem estrutura e função semelhantes à da ricina. Aqui, comparamos duas toxinas de plantas, cadeias A recombinantes de toxinas de ricina (RAC) e pulchellina (PAC), por sua capacidade de matar células que expressam HIV. Resumidamente, RAC e PAC foram produzidos em E. coli e purificados por cromatografia, depois conjugados quimicamente com dois anticorpos monoclonais anti corpo-HIV diferentes (MAcs), MAc 924 anti-gp120 ou MAc 7B2 anti-gp41. Estes conjugados foram caracterizados bioquimicamente por eletroforese microcapilar e teste BCA e imunologicamente por uma variedade de testes ELISA. Realizamos uma comparação lado-a-lado de sua capacidade de ligar, entrar e matar células infectadas pelo HIV (H9 / NL4-3) ou células 293T transfectadas com Env, bem como a sua toxicidade não específica em parentes não infectados ou não transfectados Células. A ligação celular e a internalização foram estudadas por citometria de fluxo e microscopia confocal. Os resultados mostraram que PAC pode funcionar dentro de uma TI efetiva. As TI demonstraram ligação específica contra antígenos nativos em células persistentemente infectadas pelo HIV e antígenos recombinantes em células transfectadas com Env. Um anticorpo irrelevante conjugado com RAC ou PAC não teve efeito. A citotoxicidade de PAC aparece um pouco menor que o RAC, o padrão de comparação. Este é o primeiro relatório que o PAC pode ter utilidade para o projeto e a construção de TI terapêuticas, destacando o papel potencial para o direcionamento celular específico, não apenas para a AIDS, também para a terapia do câncer.
