| Hazard Information | Back Directory | [History]
TocilizuMab (trade name: Actemra) is an antirheumatoid arthritis drug developed by Genentech, Inc. It was first approved by the FDA on January 8, 2010, for the treatment of moderate to severe active rheumatoid arthritis. On June 24, 2021, Actemra received Emergency Use Authorization from the FDA for the treatment of hospitalized adults and children with COVID-19, but not for outpatients with COVID-19. At this time, it had not yet received formal approval. By December 21, 2022, the FDA approved Actemra for the treatment of hospitalized adults with COVID-19. | [Uses]
Tocilizumab (Anti-Human IL6R, Humanized Antibody) is an anti-human interleukin-6 receptor (IL-6R) neutralizing antibody, prevents binding of IL-6 to the IL-6R, thereby inhibiting both classic and trans-signaling. Tocilizumab (Anti-Human IL6R, Humanized Antibody) can be used for the treatment of rheumatoid arthritis[1]. Tocilizumab is remarkablely effective for the study of severe COVID-19 (coronavirus disease)[4]. | [Clinical Use]
Interleukin inhibitor:
Treatment of rheumatoid arthritis in combination with methotrexate | [in vivo]
Tocilizumab (Anti-Human IL6R, Humanized Antibody) (intravenous injection; 1.0 mg/100 μL; twice a week, three weeks) decreases the volume of each metastatic focus in tocilizumab-injected mouse brains[2].
Tocilizumab (Anti-Human IL6R, Humanized Antibody) (intraperitoneal injection;100 μg/mL, every 48 hours; 20days) suppresses OSCC progression and suppresses Tumor Angiogenesis[3]. | Animal Model: | A brain metastasis model of lung tumor cells by inoculating HARA-B cells in nude mice[2] | | Dosage: | 1.0 mg/100 μL | | Administration: | Intravenous injection; 1.0 mg/100 μL; twice a week, three weeks | | Result: | Led the volume of each metastatic focus significantly smaller. |
| Animal Model: | SCID mice with SAS cells[3] | | Dosage: | 100 μg/mL | | Administration: | Intraperitoneal injection;100 μg/mL; every 48 hours; 20days | | Result: | Suppressed the growth of advanced tumors. |

IL-6 | [Metabolism]
Tocilizumab undergoes biphasic elimination from the circulation. The total clearance of tocilizumab is concentration-dependent and is the sum of the linear and non-linear clearance. The concentration-dependent non-linear clearance plays a major role at low tocilizumab concentrations. Once the non-linear clearance pathway is saturated, at higher tocilizumab concentrations, clearance is mainly determined by the linear clearance. | [storage]
