9SPECT imaging of distribution and retention of a brain-penetrating bispecific amyloid-β antibody in a mouse model of Alzheimer's disease显示文摘Background:Alzheimer's disease(AD)immunotherapy with antibodies targeting amyloid-B(AB)has been extensively explored in clinical trials.The aim of this study was to study the long-term brain distribution of two radiolabeled monoclonal Aβ antibody variants-RmAb158,the recombinant murine version of BAN2401,which has recently demonstrated amyloid removal and reduced cognitive decline in AD patients,and the bispecific RmAb158-scFv8D3,which has been engineered for enhanced brain uptake via transferrin receptor-mediated transcytosis.Methods:A single intravenous injection of iodine-125(251)-labeled RmAb158-scFv8D3 or RmAb158 was administered to AD transgenic mice(tg-ArcSwe).In vivo single photon emission computed tomography was used to investigate brain retention and intrabrain distribution of the antibodies over a period of 4 weeks.Activity in blood and brain tissue was measured ex vivo and autoradiography was performed in combination with Aβand CD31 immunostaining to investigate the intrabrain distribution of the antibodies and their interactions with AB.Results:Despite faster blood clearance,[125]RmAb158-scFv8D3 displayed higher brain exposure than[25]RmAb158 throughout the study.The brain distribution of[l25]RmAb158-scFv8D3 was more uniform and coincided with parenchymal Aβ pathology,while[2 I]RmAb158 displayed a more scattered distribution pattern and accumulated in central parts of the brain at later times.Ex vivo autoradiography indicated greater vascular escape and parenchymal Aβ interactions for[25]RmAb158-scFv8D3,whereas[25]RmAb158 displayed retention and Aβ interactions in lateral ventricles.Conclusions:The high brain uptake and uniform intrabrain distribution of RmAb158-scFv8D3 highlight the benefits of receptor-mediated transcytosis for antibody-based brain imaging.Moreover,it suggests that the alternative transport route of the bispecific antibody contributes to improved efficacy of brain-directed immunotherapy.Tobias Gustavsson Stina Syvänen Paul O'Callaghan Dag Sehlin 2020Translational Neurodegeneration2020,9,3:1

19Novel multivalent design of a monoclonal antibody improves binding strength to soluble aggregates of amyloid beta显示文摘Background:Amyloid-β(Aβ)immunotherapy is a promising therapeutic strategy in the fght against Alzheimer’s disease(AD).A number of monoclonal antibodies have entered clinical trials for AD.Some of them have failed due to the lack of efcacy or side-efects,two antibodies are currently in phase 3,and one has been approved by FDA.The soluble intermediate aggregated species of Aβ,termed oligomers and protofbrils,are believed to be key pathogenic forms,responsible for synaptic and neuronal degeneration in AD.Therefore,antibodies that can strongly and selectively bind to these soluble intermediate aggregates are of great diagnostic and therapeutic interest.Methods:We designed and recombinantly produced a hexavalent antibody based on mAb158,an Aβprotofbrilselective antibody.The humanized version of mAb158,lecanemab(BAN2401),is currently in phase 3 clinical trials for the treatment of AD.The new designs involved recombinantly fusing single-chain fragment variables to the N-terminal ends of mAb158 antibody.Real-time interaction analysis with LigandTracer and surface plasmon resonance were used to evaluate the kinetic binding properties of the generated antibodies to Aβprotofbrils.Diferent ELISA setups were applied to demonstrate the binding strength of the hexavalent antibody to Aβaggregates of diferent sizes.Finally,the ability of the antibodies to protect cells from Aβ-induced efects was evaluated by MTT assay.Results:Using real-time interaction analysis with LigandTracer,the hexavalent design promoted a 40-times enhanced binding with avidity to protofbrils,and most of the added binding strength was attributed to the reduced rate of dissociation.Furthermore,ELISA experiments demonstrated that the hexavalent design also had strong binding to small oligomers,while retaining weak and intermediate binding to monomers and insoluble fbrils.The hexavalent antibody also reduced cell death induced by a mixture of soluble Aβaggregates.Conclusion:We provide a new antibody design with increased valency to promote binding avidity to an enhanced range of sizes of Aβaggregates.This approach should be general and work for any aggregated protein or repetitive target.Fadi Rofo Jos Buijs Ronny Falk Ken Honek Lars Lannfelt Anna M.Lilja Nicole G.Metzendorf Tobias Gustavsson Dag Sehlin Linda Söderberg Greta Hultqvist 2021Translational Neurodegeneration2021,10,3:0
20ImmunoPET imaging of amyloid-beta in a rat model of Alzheimer’s disease with a bispecific,brain-penetrating fusion protein显示文摘Background:Hijacking the transferrin receptor(TfR)is an effective strategy to transport amyloid-beta(Aβ)immuno-positron emission tomography(immunoPET)ligands across the blood-brain barrier(BBB).Such ligands are more sensitive and specific than small-molecule ligands at detecting Aβpathology in mouse models of Alzheimer’s disease(AD).This study aimed to determine if this strategy would be as sensitive in rats and to assess how TfR affinity affects BBB transport of bispecific immunoPET radioligands.Methods:Two affinity variants of the rat TfR antibody,OX26,were chemically conjugated to a F(ab′)2 fragment of the anti-Aβantibody,bapineuzumab(Bapi),to generate two bispecific fusion proteins:OX265-F(ab′)2-Bapi and OX2676-F(ab′)2-Bapi.Pharmacokinetic analyses were performed 4 h and 70 h post-injection of radioiodinated fusion proteins in wild-type(WT)rats.[124I]I-OX265-F(ab′)2-Bapi was administered to TgF344-AD and WT rats for in vivo PET imaging.Ex vivo distribution of injected[124I]I-OX265-F(ab′)2-Bapi and Aβpathology were assessed.Results:More[125I]I-OX265-F(ab′)2-Bapi was taken up into the brain 4 h post-administration than[124I]I-OX2676-F(ab′)2-Bapi.[124I]I-OX265-F(ab′)2-Bapi PET visualized Aβpathology with significantly higher signals in the TgF344-AD rats than in the WT littermates without Aβpathology.The PET signals significantly correlated with Aβlevels in AD animals.Conclusion:Affinity to TfR affects how efficiently a TfR-targeting bispecific fusion protein will cross the BBB,such that the higher-affinity bispecific fusion protein crossed the BBB more efficiently.Furthermore,bispecific immunoPET imaging of brain Aβpathology using TfR-mediated transport provides good imaging contrast between TgF344-AD and WT rats,suggesting that this immunoPET strategy has the potential to be translated to higher species.Gillian Bonvicini Stina Syvänen Ken G.Andersson Merja Haaparanta-Solin Francisco López-Picón Dag Sehlin 2022Translational Neurodegeneration2022,11,1:0
