| Isoelectric Point | 8.31 |
| Hydrophobicity | -0.513 |
| Melting Point (℃) | 61 (FAB f |
| Half Life | 0.8 hours (mammalian reticulocytes, in vitro) |
| 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). |
| Indication/Disease | For treatment of organ transplant recipients, prevention of organ rejection |
| Pharmacodynamics | 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. |
| Mechanism of Action | 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. |
| Toxicity | N.A. |
| Metabolism | Most likely removed by opsonization via the reticuloendothelial system. |

| Brand Name | ORTHOCLONE OKT3Â STERILE SOLUTION |
| Company | Centocor Ortho Biotech, L.P. |
| Brand Discription | The antibody is a biochemically purified IgG2a immunoglobulin with a heavy chain of approximately 50,000 daltons and a light chain of approximately 25,000 daltons. It is directed to a glycoprotein with a molecular weight of 20,000 in the human T cell surface which is essential for T cell functions. Because it is a monoclonal antibody preparation, ORTHOCLONE OKT3 Sterile Solution is a homogeneous, reproducible antibody product with consistent, measurable reactivity to human T cells. |
| Prescribed for | ORTHOCLONE OKT3 is indicated for the treatment of acute allograft rejection in renal transplant patients. ORTHOCLONE OKT3 is indicated for the treatment of steroid-resistant acute allograft rejection in cardiac and hepatic transplant patients. |
| Chemical Name | N.A. |
| Formulation | Each 5 mL ampule of ORTHOCLONE OKT3 Sterile Solution contains 5 mg (1 mg/mL) of muromonab-CD3 in a clear colorless solution which may contain a few fine translucent protein particles. Each ampule contains a buffered solution (pH 7.0 ± 0.5) of monobasic sodium phosphate (2.25 mg), dibasic sodium phosphate (9.0 mg), sodium chloride (43 mg), and polysorbate 80 (1.0 mg) in water for injection. |
| Physcial Appearnce | ORTHOCLONE OKT3 (muromonab-CD3)sterile solution is a murine monoclonal antibody to the CD3 antigen of human T cells which functions as an immunosuppressant. |
| Route of Administration | For Intravenous Use Only |
| Recommended Dosage | The recommended dose of ORTHOCLONE OKT3 for the treatment of acute renal, steroid-resistant cardiac, or steroid-resistant hepatic allograft rejection is 5 mg per day in a single (bolus) Intravenous infusion in less than one minute for 10 to 14 days. |
| Contraindication | not given to patient which are hypersensitive to this or any other product of murine origin, have anti-mouse antibody titers ≥1:1000; are in (uncompensated) heart failure or in fluid overload, as evidenced by chest X-ray or a greater than 3 percent weight gain within the week prior to planned ORTHOCLONE OKT3 administration; have uncontrolled hypertension; have a history of seizures, or are predisposed to seizures. |
| Side Effects | RTHOCLONE OKT3 therapy includes adverse effects: Dyspnea(21%), nausea(19%), vomiting (19%), chest pain (14%), diarrhea (14%), tremor (13%), wheezing (13%), headache (11%), tachycardia (10%), rigor (8%), and hypertension (8%), Angina, Cardiac Arrest, Fluctuation in Blood Pressure, Heart Failure, Myocardial Infarction, Shock, Thrombosis, Coma, Encephalopathy, Epilepsy, Hypotonia, Gastrointestinal Hemorrhage, Coagulation Disorder, Lymphadenopathy, Lymphopenia, Anuria, Oliguria, Apnea, Pneumonitis, Conjunctivitis, Hearing Decreases. |
