Investigational Drug Details
| Drug ID: | D251 | 
| Drug Name: | OKT3 | 
| Synonyms: | Anti-CD3; Muromonab-CD3 | 
| Type: | Biological drug | 
| DrugBank ID: | DB00075 | 
| DrugBank Description: | Murine monoclonal antibody specific to CD3 T-cell lymphocyte antigens. More specifically it is a purified murine (mouse) monoclonal antibody, directed against the CD3 (T3) receptor on the surface of human T-cells (T-lymphocytes) cultured using the murine ascites method. Muromonab is 93% monomeric immune globulin G type 2a (IgG2a). |

| Molecular Weight: | -- | 
| DrugBank Targets: | T-cell surface glycoprotein CD3 delta chain; T-cell surface glycoprotein CD3 epsilon chain binder; T-cell surface glycoprotein CD3 gamma chain; T-cell surface glycoprotein CD3 zeta chain; Low affinity immunoglobulin gamma Fc region receptor III-B | 
| DrugBank MoA: | Muromonab binds to the T-cell surface glycoprotein CD3 epsilon chain. It appears to kill CD-3 positive cells by inducing Fc mediated apoptosis, antibody mediated cytotoxicity and complement-dependent cytotoxicity. | 
| DrugBank Pharmacology: | Used in organ transplant prophylaxis, Muromonab or OKT-3 binds specifically to the CD-3 complex, which is involved in antigen recognition and cell stimulation, on the surface of T lymphocytes. Immediately after administration CD-3-positive T lymphocytes are abruptly removed from circulation. It has been effective in reversing corticosteroid-resistant acute rejection in renal, liver, and cardiac transplant recipients. | 
| DrugBank Indication: | For treatment of organ transplant recipients, prevention of organ rejection | 
| Targets: | CD3E antagonist | 
| Therapeutic Category: | Immunosuppressant | 
| Clinical Trial Progress: | Phase 2 completed (NCT01205087) | 
| Latest Progress: | Under clinical trials |
