Abstract:
Enlonstobart (Enshuxing®), a recombinant, fully humanised immunoglobulin G4 monoclonal antibody targeted against programmed cell death protein 1 (PD-1), is being developed by the CSPC Pharmaceutical Group for the treatment of advanced cervical cancer and other solid tumours. Enlonstobart received its first approval (a conditional marketing authorisation) in June 2024, in China, for use in patients with recurrent or metastatic programmed cell death ligand 1 (PD-L1)-positive cervical cancer who have failed previous platinum-containing chemotherapy. Phase III clinical evaluation of enlonstobart for use as first-line treatment (in combination with chemotherapy ± bevacizumab) in patients with recurrent or metastatic PD-L1-positive cervical cancer is also underway in China. Additionally, phase II clinical development of enlonstobart (as a part of combination therapy) for use against a range of other solid tumour types is continuing. This article summarises the milestones in the development of enlonstobart leading to this first approval for recurrent or metastatic cervical cancer.
