概要
Efgartigimod blocks the neonatal Fc receptor, which recycles IgG and protects it from degradation. Denosumab is an IgG2 antibody, so its exposure and bone-protective effect could theoretically fall. Clinical data are lacking.
この相互作用をわかりやすく説明すると
Denosumab and Efgartigimod alfa can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Denosumab belongs to Oncology; Efgartigimod alfa belongs to Miscellaneous.
なぜ起こるのか
FcRn blockade accelerates IgG catabolism and may lower denosumab concentrations.
対処法
Monitor bone turnover markers and bone density response, and watch for loss of effect such as rising resorption markers. If denosumab is essential long term, consider the timing of efgartigimod cycles or alternative antiresorptives.
