How Nucala works
Nucala is a targeted anti-IL-5 add-on therapy for adults, adolescents and children ≥ 6 years with severe refractory eosinophilic asthma. 1
Nucala is a humanised monoclonal antibody that inhibits the bioactivity of interleukin (IL)-5. 1Nucala blocks the binding of IL-5 to the alpha chain of the IL-5 receptor complex on the eosinophil cell surface. This inhibits IL-5 signalling and reduces the growth, differentiation, recruitment, activation and survival of eosinophils. 123
What is the pharmacodynamic effect of Nucala?
In clinical studies, Nucala added to high dose ICS and an additional maintenance treatment(s) reduced blood eosinophil levels by 84% compared with placebo added to high dose ICS and an additional maintenance treatment(s). 4
Nucala treatment led to a reduction in geometric mean count from 290 cells/μL (0.29 x 109 cells/L) at baseline to 40 cells/μL (0.04 x 109 cells/L) at Week 32. 1
