                                        Comment: Plonmarlimab (TJM2/TJ003234) is a humanized IgG1 monoclonal antibody that is designed to neutralise granulocyte-macrophage colony-stimulating factor (GM-CSF; CSF2) cytokine activity. It was developed by I-Mab Biopharma for potential to treat autoimmune diseases, and is likely to be Hu23F4-27 as claimed in I-Mab patent WO2018050111A1 [2].  
                            
                            
                          
                                
                                    
                                
                          
                                   
                                   
                                  
                                    
                                    
                                    COVID-19: Plonmarlimab is being evaluated as a mechanism to down-regulate elevated inflammation/cytokine release syndrome in patients with COVID-19 [1] in a Phase 2/3 study.  |
