                                        Comment: Zansecimab (LY3127804) is a humanised IgG4 monoclonal antibody that targets angiopoietin 2 (Ang2). It was designed and developed by Eli Lilly to block angiogenesis as an anti-tumour mechanism. As Ang2 is elevated in acute respiratory distress syndrome (ARDS), Eli Lilly chose to evaluate LY3127804 in patients hospitalised with COVID-19 pneumonia, to ascertain if this approach could reduce the risk of developing ARDS in at risk patients. The COVID study was terminated for futility after around 6 months. 
                            
                            
                          
                                
                                    
                                
                          
                                   
                                   
                                  
                                    
                                    
                                    The peptide chain sequences of zansecimab (from its INN submission) are identical to sequences claimed in Eli Lilly's patent WO2015179166A1: sequences 2 and 4 comprise the heavy and light chains of the mAb designated as 'Antibody A' in the patent [1].  |
