Monoclonal Ab's Flashcards
Abatacept
CTLA4 fusion protein –> blocks CD80/CD86 –> prevents binding of T cell CD28 to APC CD80/CD86 –> prevents T cell activation RA
Anakinra
Recombinant form of human IL-1 Autoinflamm diseases, refractory RA
Nivolimab
PD-1 antibody –> binds PD-1 on T cells to prevent binding with PD-L1 from tumour cells –> reactivation of tumour T cells
Co-stimulatory pathway modulators
Abatcept, Ipilimumab CTLA4 pathway Nivoliumab, Pembrolizumab PD-1 antibody Atezolizumab, Tixolinumab PD-L1 antibody
Mepolizumab
IL-5 antibody Severe refractory eosinophilic asthma
Atezolizumab
PD-L1 antibody –> binds PD-L1 on tumour cells to prevent binding with PD-1 from T cells –> reactivation of tumour T cells
Rituximab
CD20 antibody Removes B cells from circulation for 6-9/12 Haematological malignancies, RA, SLE, immune thrombocytopaenia, autoimmune haemolysis, ANCA vasculitis, cryoglobulinaemia, MS, pemphigus
Ipilimumab
CTLA4 blcoker –> prevents binding of T cell CTLA4 to APC CD80/CD86, but maintains T cell stimulation Melanoma, prostate Ca, lung Ca
Golimumab
TNF-alpha
Tocilizumab
IL-6 antibody Refractory RA
Idarucizumab
Monoclonal antibody binds to Dabigatran & metabolites with very high affinity (300x affinity of dabigatran) Dabigatran reversal agent for life threatening bleeding or emergency surgery
Lorlatinib
EML4-ALK inhibitor (3rd generation) AML4/ALK = aberrant active fusion protein present in ~5% of lung adenoCa Non-curable EML4/ALK positive lung adenoCa This is now standard of care, superior to crizotinib
Sorafenib
Multi-kinase inhibitor: Raf signalling, VEGF, PDGF, C-kit HCC
Dasatanib
BCR-Abl inhibitor
BCR-Abl positive CML
GIST Disease progression on imatinib
Natalizumab
Alpha-4 integrin antibody –> blocks T cell entry into brain and gut (Brain homing T cells express alpha-4-beta-1 which binds VCAM-1 expressed on brain endothelium) Multiple sclerosis, Crohn’s
EML4-ALK inhibitors
Crizotinib (1st generation) Ceritinib (2nd generation) Alectinib (2nd generation) Lorlatinib (3rd generation)
