Description: |
Tocilizumab is a recombinant humanized anti-human interleukin 6 (IL-6) receptor monoclonal antibody of the immunoglobulin IgG1κ (gamma 1, kappa) subclass with a typical H2L2 polypeptide structure. Each light chain and heavy chain consists of 214 and 448 amino acids, respectively. The four polypeptide chains are linked intra-and inter-molecularly by disulfide bonds. Tocilizumab has a molecular weight of approximately 148 kDa. The antibody is produced in mammalian (Chinese hamster ovary) cells.
Tocilizumab binds to both soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R) and has been shown to inhibit IL-6-mediated signaling through these receptors. IL-6 is a pleiotropic pro-inflammatory cytokine produced by a variety of cell types including T- and B-cells, lymphocytes, monocytes, and fibroblasts. IL-6 has been shown to be involved in diverse physiological processes such as T-cell activation, induction of immunoglobulin secretion, initiation of hepatic acute phase protein synthesis, and stimulation of hematopoietic precursor cell proliferation and differentiation. IL-6 is also produced by synovial and endothelial cells leading to local production of IL-6 in joints affected by inflammatory processes such as rheumatoid arthritis.
Regulatory Status
Tocilizumab (e.g., Actemra) is approved by the U.S. Food and Drug Administration (FDA) for the following indications:
On March 5, 2024, the U.S. Food and Drug Administration approved tocilizumab-aazg (e.g., Tyenne) for intravenous use as biosimilar to tocilizumab (e.g., Actemra) for the following indications:

Rationale: |
Tocilizumab intravenous infusion was approved for rheumatoid arthritis based on the efficacy and safety of five randomized, double-blind, multicenter studies in patients 18 years of age or older with active rheumatoid arthritis.
In Study 1 Tocilizumab was given intravenously every four weeks as monotherapy in patients who had not been treated with methotrexate within 24 weeks prior to randomization. 67% of these patients were methotrexate naïve. Patients received 8mk/kg Tocilizumab monotherapy or methotrexate alone. The primary endpoint was the number of patients who achieved an ACR 20 response at Week 24. At Week 24 53% of methotrexate patients and 70% of Tocilizumab treated patients achieved an ACR 20 response.
In Study 2 patients received 4mg/kg of Tocilizumab, 8mg/kg of Tocilizumab, or placebo intravenously once every four weeks. Each treatment arm was given in combination with methotrexate. All of these patients had previously experienced an inadequate clinical response to methotrexate. At Week 24 27% of placebo patients, 51% of 4mg/kg dosing Tocilizumab patients, and 56% of 8mg/kg dosing Tocilizumab patients achieved an ACR 20 response.
Study 3 also evaluated patients who had an inadequate clinical response to methotrexate. Patients received 4mg/kg of Tocilizumab, 8mg/kg of Tocilizumab, or placebo intravenously once every four weeks in combination with methotrexate. At Week 24 27% of placebo patients, 48% of 4mg/kg dosing Tocilizumab patients, and 59% of 8mg/kg dosing Tocilizumab patients achieved an ACR 20 response.
Study 4 evaluated patients who had an inadequate response to one or more DMARD. Patients received 8mg/kg Tocilizumab or placebo intravenously once every four weeks in combination with a DMARD. At Week 24 24% of placebo patients and 61% of Tocilizumab patients achieved an ACR 20 response.
Study 5 evaluated patients who had an inadequate clinical response or were intolerant to one or more TNF antagonist therapies. The TNF antagonist was discontinued prior to randomization. Patients received 4mg/kg of Tocilizumab, 8mg/kg of Tocilizumab, or placebo intravenously once every four weeks in combination with methotrexate. At Week 24 10% of placebo patients, 30% of 4mg/kg dosing Tocilizumab patients, and 50% of 8mg/kg dosing Tocilizumab patients achieved an ACR 20 response.
In all intravenous studies, patients treated with 8 mg/kg Tocilizumab had higher ACR 20, ACR 50, and ACR 70 response rates versus MTX- or placebo-treated patients at week 24. During the 24 week controlled portions of Studies 1 to 5, patients treated with Tocilizumab at a dose of 4 mg/kg in patients with inadequate response to DMARDs or TNF antagonist therapy had lower response rates compared to patients treated with Tocilizumab 8 mg/kg. (Actemra, 2020)
Tocilizumab intravenous infusion was approved for polyarticular juvenile idiopathic arthritis based on the safety and efficacy of a three-part study. Patients two to seventeen years of age with polyarticular juvenile idiopathic arthritis who had an inadequate response or inability to tolerate methotrexate were included in the study. Patients had a least six months of active disease and were allowed to continue the use of methotrexate. Other DMARDs or biologics were not permitted in the study.
Part I consisted of a 16-week active Tocilizumab treatment lead-in period. Patients weighing less than 30kg were given either Tocilizumab 8mg/kg or 10mg/kg intravenously once every four weeks. At the end of Part I, 91% of patients taking methotrexate plus Tocilizumab and 83% of patients taking Tocilizumab monotherapy achieved an ACR 30 response compared to baseline. Part II consisted of a 24-week randomized double-blind placebo controlled withdrawal period. Patients were randomized to Tocilizumab or placebo. The primary end point was the proportion of patients with an ACR 30 flare at week 40 relative to week 16. Tocilizumab treated patients experienced significantly fewer disease flares compared to placebo-treated patients, 26% versus 48%. Part III consisted of a 64-week open-label period.
Tocilizumab intravenous infusion was approved for systemic juvenile idiopathic arthritis based on a 12-week randomized, double blind, placebo-controlled study. 112 patients were randomized. 75 patients received Tocilizumab every two weeks at either 8mg/kg for patients at or above 30kg or 12mg/kg for patients less than 30kg. 37 patients received placebo every two weeks. The primary endpoint was the proportion of patients with at least 30% improvement in JIA ACR 30 response. At week 12 91% of patients receiving Tocilizumab and 24% of patients receiving placebo had a ACR 30 response.
Tocilizumab intravenous infusion was approved for cytokine release syndrome based on a retrospective analysis of pooled outcome data from clinical trials of CAR T-cell therapies for hematological malignancies. Patients had been treated with Tocilizumab 8mk/kg (12mg/kg for patients less than 30kg) with or without additional high-dose corticosteroids for severe or life-threatening CRS. 45 patients were evaluated. 31 patients (69%) achieved a response.

2024 Update
Subcutaneous tocilizumab (TCZ SC) is approved globally for giant cell arteritis (GCA). This phase Ib study investigated the pharmacokinetics, pharmacodynamics, safety, and exploratory efficacy of intravenous (IV) TCZ 6 and 7 mg/kg in patients with GCA. This study explored an IV dose resulting in a minimum exposure level within the range of effective trough concentrations achieved with TCZ SC dosing in GCA and not exceeding the exposure of the well-tolerated 8 mg/kg IV every 4 weeks (Q4W) in rheumatoid arthritis (RA).
Patients with GCA who had received ≥ 5 doses of TCZ IV 8 mg/kg Q4W and achieved remission were enrolled. Patients received 5 doses of TCZ IV 7 mg/kg Q4W in period 1 and, if still in remission, 5 doses of 6 mg/kg Q4W in period 2. Pharmacokinetic endpoints were maximum concentration, minimum concentration, area under the curve over a dosing interval, and mean concentration of TCZ after the last dose of each period. Other endpoints included pharmacodynamic markers, safety, and exploratory efficacy.
In 24 patients, the median (range) age was 65.5 (57-90) years, and 62.5% were female. TCZ exposures were 11.2% and 20.0% lower at the 6- than 7-mg/kg dose. The mean interleukin 6 (IL-6) serum concentrations were elevated at baseline and remained elevated, with slightly higher concentrations in period 1 than in period 2. The mean serum soluble IL-6 receptor concentrations were elevated at baseline and comparable between the 2 doses at steady state. C-reactive protein levels and most erythrocyte sedimentation rates were within normal ranges throughout the study. Overall, 22 patients (91.7%) had ≥ 1 adverse event, and 4 (16.7%) had a serious adverse event. No patients experienced a GCA flare, and all remained in remission throughout the study.
Both doses of TCZ IV Q4W were generally well tolerated in patients with GCA. The maximum concentration and mean concentration achieved with 6 mg/kg IV Q4W in patients with GCA were similar to those in patients with RA treated with 8 mg/kg IV Q4W, and Ctrough was within the range observed in patients with GCA treated with SC dosing every week or every 2 weeks.
