Comprehensive Preclinical Safety Evaluation Of Antibody-Drug Conjugates (ADCs) nyob rau hauv Non-Human Primates

Kev soj ntsuam kev nyab xeeb ua ntej rau ADCs yuav tsum tau ua raws li Kev Ntsuas Zoo (GLP) cov qauv, tshwj tsis yog rau qee qhov kev tshawb nrhiav hauv cov theem kev loj hlob thaum ntxov, uas tuaj yeem ua raws li tsis yog -GLP tej yam kev mob yog tias tsim nyog, nrog rau kev cuam tshuam ntawm cov ntaub ntawv zoo qhia meej.

 

Shanghai Prisys Biotech Co., Ltd.specializes nyob rau hauv lub preclinical thiab translational ntsuam xyuas ntawm tshiab tshuaj technologies, tsom rautsis yog-tus qauv kab mob tib neeg primate (NHP).thiab cov tswv yim tswv yim ua raws li cov qauv tshuaj thoob ntiaj teb. Ua haujlwm thoob ntiaj teb cov tuam txhab tshuaj, cov tuam txhab biopharmaceutical, cov chaw tshawb fawb, cov chaw kho mob thev naus laus zis, thiab cov koom haum R&D, Prisys Biotech muaj cov kev daws teeb meem zoo rau kev siv tshuaj kho mob thiab kev txhais lus nce qib ntawm kev kho tshiab. Lub tuam txhab siv lub platform tshwj xeeb tshwj xeeb rau NHP qauv rau tib neeg cov kab mob loj, txhawm rau txuas rau thaum ntxov- kev tshawb fawb tshuaj nrog rau kev siv tshuaj kho mob ntawm kev lag luam.

 

 

 

1. Kev soj ntsuam ntawm ADC Test Formulation

Cov qauv kuaj ADC yuav tsum ua kom txaus sawv cev rau cov yam ntxwv zoo ntawm cov uas npaj rau kev sim tshuaj. Cov ntaub ntawv qhia ntxaws txog lawv cov khoom physicochemical yuav tsum muaj cov ntaub ntawv ntawm qhov chaw, batch tooj, purity, concentration, thiab muaj pes tsawg leeg. ADC tshuaj-rau- cov tshuaj tiv thaiv kab mob (DAR) cuam tshuam rau toxicity; Yog li, DAR ruaj khov yuav tsum tau txheeb xyuas ob qho tib si hauv kev sim daws teeb meem ua ntej kev tswj hwm thiab thoob plaws kev tuav. Cov concentration yuav tsum tau ntsuas ua ntej kev tswj hwm, thiab DAR rov ntsuas dua yog tias muaj kev tso cai.

 

 

2. Kev xaiv tsiaj txhu rau ADC kev kawm txog kev nyab xeeb

ADC muaj pes tsawg leeg suav nrog cov tshuaj tiv thaiv kab mob, txuas txuas, thiab cytotoxic payload, sib txuas cov yam ntxwv ntawm ob qho tib si biologics thiab tshuaj lom neeg. Yog li, xaiv cov qauv tsiaj tsim nyog yog qhov tseem ceeb, tshwj xeeb tshaj yog cov neeg muaj feem cuam tshuam los yog cov tshuaj antigens rau ADC khi thiab cov tshuaj siv tshuaj. Yog tias nas tsis tsim nyog, ib hom tsis yog - tib neeg tuaj yeem xaiv tau. Rau qhov tsis paub me me -molecule toxicity, luv- cov kev tshawb fawb luv luv yuav raug ua nyob rau hauv nas los sib piv ADC toxicity ua ntej thiab tom qab cov tshuaj tiv thaiv kab mob.

Nyob rau hauv rooj plaub uas tsuas yog ib hom kab ntsig raug txheeb xyuas, ib qho kev tshawb fawb ib hom - tej zaum yuav raug tsim nyog. Yog tias tsis muaj hom kab mob tshwm sim, lwm cov molecules lossis cov qauv tsiaj (xws li cov tsiaj transgenic qhia txog tib neeg lub hom phiaj) tuaj yeem siv tau, tab sis cov txiaj ntsig yuav tsum tau ua tib zoo ntsuas rau tib neeg kev kwv yees qhov tseeb.

 

 

 

3. Kev Tshawb Fawb Txog Kev Toxic

Tus qauv mob hnyav thiab rov ua dua - kev tshawb fawb tshuaj toxicity muab lub hauv paus rau ADC kev ntsuam xyuas kev nyab xeeb. Cov kev tshawb fawb ADC feem ntau koom nrog tag nrho cov molecule, txawm hais tias cov kev tshawb fawb cais yuav ntsuas cov khoom tshwj xeeb nyob ntawm lub hom phiaj kev koom tes. Yog tias cov molecule me tau pom zoo lossis muaj cov ntaub ntawv kev nyab xeeb txaus, cov kev tshawb fawb cais yuav tsis tsim nyog. Txawm li cas los xij, tshiab lossis qis dua - tshawb nrhiav cov molecules me me tuaj yeem xav tau kev tshawb fawb txog tshuaj lom neeg nyob ib leeg, feem ntau hauv cov nas, txhawm rau txheeb xyuas cov tshuaj lom ntawm qhov siab tshaj plaws.

Vim yog ntev ib nrab ntawm - lub neej ntawm ADC cov tshuaj tiv thaiv kab mob, lub sij hawm soj ntsuam hauv ib zaug - kev tshawb fawb koob tshuaj tuaj yeem txuas ntxiv mus ntes cov lus teb qeeb. Feem ntau, rov ua dua- kev tshawb fawb koob tshuaj tsis pub dhau peb lub hlis.

4. Tissue Cross-Reactivity (TCR) Studies

Cov kev tshawb fawb TCR muab kev nkag siab txog cov tshuaj tiv thaiv kab mob sib txuas nrog lub hom phiaj thiab tsis yog - cov ntaub so ntswg, txawm hais tias cov lus qhia tsis ntev los no tau txo qis lawv qhov tsim nyog vim muaj kev txwv hauv qhov tsis yog - kho mob kwv yees tus nqi. Cov kev cai tswjfwm sib txawv, tab sis kev tshawb fawb TCR hauv tib neeg lossis NHP cov ntaub so ntswg raug pom zoo rau ADCs nrog cov hloov pauv hloov tshiab los ntsuas qhov muaj peev xwm tawm ntawm - cov teebmeem.

 

 

5. Toxicokinetics (TK) Kev Tshawb Fawb

Kev ntsuam xyuas TK tau koom ua ke nrog kev tshawb fawb txog tshuaj lom, muab ADC cov ntaub ntawv nthuav tawm thiab txhawb nqa thawj zaug -hauv- tib neeg (FIH) kev xaiv koob tshuaj. TK kev ntsuas, suav nrog cov qauv me me dawb thiab cov qib ADC tsis zoo, muab kev pom ntawm PK tsis muaj thiab kev ruaj ntseg hauv vivo. Kev sib xyaw TK nrog PK cov kev tshawb fawb feem ntau siv tau hauv cov qauv tsis yog- nas.

 

 

 

6. Kev ntsuam xyuas Immunogenicity

Raws li ADCs suav nrog cov tshuaj tiv thaiv kab mob, lawv tuaj yeem ua rau lub cev tiv thaiv kab mob. Ib qho -tiered xeem mus kom ze- npog kev tshuaj ntsuam, titering, neutralization, thiab subtype tsom xam- raug pom zoo los soj ntsuam immunogenicity. Kev tshawb fawb txog kev tiv thaiv kab mob feem ntau yog ua nrog rov ua dua- kev tshawb fawb txog tshuaj toxicity, sau cov qauv ntawm lub sijhawm sib txawv los tshuaj xyuas kev tsim tshuaj tiv thaiv - tshuaj tiv thaiv kab mob (ADA).

 

 

7. Kev tshawb fawb txog Genotoxicity

ADC cov cuab yeej cuab tam txhais tau hais tias kev pheej hmoo ntawm caj ces toxicity feem ntau yog los ntawm cov molecule me, yog li kev kuaj genotoxicity ntawm ADCs lawv tus kheej yuav tsis tsim nyog. Yog hais tias lub me me molecule yog tshiab los yog muaj ib tug tsis meej mechanisms, cov kev ntsuam xyuas genotoxicity yuav tsum tau ua, tsom rau cov feem cuam tshuam raws li ADC stability, kev ua, thiab degradation txoj kev.

 

 

8. Kev Nyab Xeeb Pharmacy

Rau kev tiv thaiv- mob qog noj ntshav, ICH cov lus qhia feem ntau tsis tas yuav muaj kev tshawb fawb txog kev nyab xeeb nyob ib leeg. Yog hais tias lub me me molecule yog ib tug tshiab cytotoxin, kev kuaj hERG tej zaum yuav tsim nyog los ntsuam xyuas lub peev xwm cardiotoxicity.

 

 

Prisys Biotech sawv ntawm lub hauv ntej ntawm biopharmaceutical innovation, tau cog lus los tsim kom muaj kev lag luam platform rau kev tsim NHP qauv rau tib neeg cov kab mob tseem ceeb. Los ntawm kev txhawb nqa kev sib koom tes thoob ntiaj teb thiab cov haujlwm hauv tsev, nrog rau tsoomfwv -cov haujlwm tau txais nyiaj, Prisys Biotech muab cov kev tshawb fawb tshawb fawb nrog cov peev txheej lag luam txhawm rau nthuav dav biomedicine cov ntawv thov kho mob. Qhov kev mob siab rau kev nce qib biopharmaceutical txhais lus tsim cov cib fim tshiab thiab kev txhawb nqa thev naus laus zis rau txoj kev loj hlob ntawm kev lag luam, qhia txog Prisys Biotech lub luag haujlwm ua tus tseem ceeb hauv ntiaj teb kev tshawb fawb txog lub neej ecosystem.
