Bimekizumab (alternative names: CDP-4940 and UCB-4940) is a monoclonal
antibody that targets IL-17A and IL-17F. Bimekizumab is developed by UCB. Adis
insight mentions a phase 3 study for psoriatic arthritis [1]. In 2018 the phase
3 study (BE READY) for plaque psoriasis has been initiated in the USA
(NCT03410992): another phase 3 study (BE SURE / NCT03412747) is under plan.
Bimekizumab has been launched with two studies at the 2017 ACR Annual Meeting in San
Diego.
A. Maroof and colleagues presented [2]: “Bimekizumab Dual Inhibition of
IL-17A and IL-17F Provides Evidence of IL-17F Contribution to Chronic
Inflammation in Disease-Relevant Cells”. The authors concluded: “Dual
neutralization of IL-17A and IL-17F provides evidence for the contribution of
IL-17F to inflammation in joints and skin beyond IL-17A alone. Dual inhibition
of IL-17A and IL-17F by bimekizumab may provide an effective treatment for
immune-mediated inflammatory diseases such as PsA [psoriatic arthritis].” Nice
to know, but …
M. Shah and colleagues elucidated us on [3]: “Bimekizumab Blocks T
Cell-Mediated Osteogenic Differentiation of Periosteal Stem Cells: Coupling
Pathological Bone Formation to IL-17A and IL-17F Signaling”. The authors
concluded: “These data show that both IL-17A and IL-17F enhance in vitro
osteogenic differentiation and bone formation […], hence inhibition of both
IL-17A and IL-17F with bimekizumab offers an attractive therapeutic strategy to
prevent this debilitating feature of SpA [spondyloarthritis].” Also nice to
know, but …
Secukinumab (Cosentyx, a human IgG1κ MAB that binds to the protein
interleukin IL-17A), brodalumab (Siliq in the US, Kyntheum in Europe, a human MAB
that binds to the IL-17-receptor), and ixekizumab (Taltz, a humanized MAB
binding to IL-17) are already out on the market. I’m not sure, what UCB is
doing. I remember UCB attending the industry exhibition ofan Annual Meetings of
ACR or EULAR with an empty information stall, as certolizumab hasn’t been
approved in time. Is UCB slowing down, because the market already has been split
up? The two studies are perfectly O.K., but not coming up with a phase 1 or 2
study at the 2017 ACR Annual Meeting must be called lack of commitment.
