Summary of Clinical Use Click here for help
Utomilumab (PF-05082566) is in early stage clinical trials in patients with various solid and liquid tumour types. Click here to link to the PF-05082566 trials registered with ClinicalTrials.gov. Preliminary (and as yet unpublished) results from NCT02179918 (PF-05082566 in combination with the PD-1 checkpoint inhibitor pembrolizumab) indicate positive responses in 6 out of 23 patients with advanced cancers.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
Utomilumab acts as a ligand, activating 4-1BB and leading to enhanced T cell activity and cytokine production, which elicits improved destruction of cancer cells. It is hypothesised that combining this immune system activation with checkpoint inhibition (e.g. with anti-PD-1, or anti CTLA-4 antibodies) will offer more effective therapy against many types of cancer.
