About naptumomab
Naptumumab (naptumomab estafenatox, ANYARA), is a tumor targeting immunotherapy that enhances the ability of the immune system to recognize and kill the tumor. Naptumomab induces the activation and expansion of specific T cells outside of the tumor microenvironment and redirect the T cells to attack the tumor cells. Naptumumab is currently being studied in an open-label, multicenter, dose-finding Phase 1b trial enrolling patients with previously treated advanced or metastatic tumors. Patients will be treated with a combination of naptumomab and durvalumab. More information about the study is available at clinicaltrials.gov (NCT03983954).

Naptumomab was licensed from Active Biotech to NeoTX Therapeutics Ltd in 2016. NeoTX is responsible for the global development and commercialization of naptumomab for the treatment of cancer under the license agreement.
