DefinitionThis section has been translated automatically.
Mogamulizumab is a monoclonal antibody against the chemokine receptor 4(CCR4) that has been shown to be effective in various T-cell lymphomas. It has been approved by the US Food and Drug Administration (FDA) for the treatment of adult patients with relapsed or refractory mycosis fungoides (MF) or Sézary syndrome (SS) who have been treated with at least one prior line of therapy (Moore DC et al. 2020). Mogamulizumab showed a significant improvement in progression-free survival compared to vorinostat in patients with relapsed or refractory MF or SS.
Pharmacodynamics (Effect)This section has been translated automatically.
Mogamulizumab is a monoclonal antibody that selectively targets the C-C chemokine receptor 4(CCR4), which is overexpressed on the surface of malignant T lymphocytes and supports the extravasation of T lymphocytes into the skin. CCR4 is a G-protein-coupled receptor for CC chemokines and is involved in cell trafficking from lymphocytes to various organs including the skin.
Preclinical studies have demonstrated in vitro and in vivo that binding of mogamulizumab to CCR4 on the surface of T lymphocytes induces antibody-dependent cellular cytotoxicity, thereby reducing the population of labeled T lymphocytes. After binding of mogamulizumab to CCR4 on the surface of the target cell, natural killer cells are activated, which subsequently mediate the destruction of the target cell.

PharmacokineticsThis section has been translated automatically.
Biotransformation: The metabolic pathway of mogamulizumab has not been described, but it is expected that mogamulizumab is degraded into small peptides and amino acids via catabolic pathways in the same manner as endogenous IgG. Elimination: According to a PK population analysis, the geometric mean (% coefficient of variation [CV%]) clearance (CL) is 12.0 ml/h (83.7%) and the geometric mean elimination half-life (t1/2) is 17 days (65.5%).
IndicationThis section has been translated automatically.
Mogamulizumab is the first CCR4 inhibitor in its class and represents a new option for the treatment of relapsed or refractory cutaneous T-cell lymphomas. Mogamulizumab is used to treat adult patients with mycosis fungoides or Sézary syndrome who have received at least one prior systemic therapy. mycosis fungoides and Sézary syndrome are the two most common subtypes of cutaneous T-cell lymphomas (Tawa M et al. (2019).
Pregnancy/nursing periodThis section has been translated automatically.
For precautionary reasons, mogamulizumab should not be used during pregnancy. It is known that IgG antibodies in humans pass into breast milk in the first few days after birth and drop to low concentrations soon afterwards. Therefore, a risk to the breastfed child cannot be excluded during this short period. Thereafter, mogamulizumab could be administered during breastfeeding if clinically necessary.
Dosage and method of useThis section has been translated automatically.
The recommended dose is 1 mg/kg mogamulizumab as an intravenous infusion over at least 60 minutes. Use is weekly on days 1, 8, 15, and 22 of the first 28-day cycle. Thereafter, infusions are given biweekly on days 1 and 15 of each subsequent 28-day cycle until disease progression or unacceptable toxicity.
Undesirable effectsThis section has been translated automatically.
The following side effects occurred very frequently (≥1/10) during the use of mogamulizumab (Blackmon AL et al. 2020):
- Infusion-related reactions (32 %)
- Drug exanthema (20 %)
- Diarrhea (23 %)
- fatigue (22 %)
Furthermore:
- peripheral edema
- fever
- infections
Serious side effects in clinical studies were respiratory insufficiency of grade 4 severity (1.1%), side effects of grade 5 severity were polymyositis and sepsis (0.5% each).
Individual case reports of exacerbations of psoriasis vulgaris during treatment with mogamulizumab are available (Lehner G 2021).

Note(s)This section has been translated automatically.
In the open-label, international, randomized, controlled phase III study (MAVORIC study), patients with relapsed or refractory mycosis fungoides or Sézary syndrome were recruited at 61 medical centers. 372 eligible patients randomly received weekly 1.0 mg/kg mogamulizumab (n=186) intravenously for the first 28-day cycle, then on days 1 and 15 of subsequent cycles, or daily 400 mg vorinostat (n=186). Patients were over 18 years of age and had received at least one prior systemic therapy that did not improve progression or cause toxicity (Kim YH et al 2018).
Results: Mogamulizumab therapy resulted in superior progression-free survival compared with vorinostat therapy at 3.1 months [2,9-4). Mogamulizumab thus significantly prolonged progression-free survival compared to vorinostat Grade 3-4 adverse events of any cause were reported in 75 (41%) of 184 patients in the mogamulizumab group and 76 (41%) of 186 patients in the vorinostat group. The most common serious adverse events of any cause patients in the mogamulizumab group were fever in 8 (4%) patients and erysipelas in 5 (3%) patients. In the vorinostat group, erysipelas and pulmonary embolism each occurred in 6 (3%) patients and sepsis in 5 (3%) patients. Two (67%) of three deaths during treatment with mogamulizumab (due to sepsis and polymyositis) and three (33%) of nine deaths during treatment with vorinostat (two due to pulmonary embolism and one due to bronchopneumonia) were considered to be a result of treatment.
