Mechanism of action

CSF1R inhibition decreases the recruitment and survival of tumor-associated macrophages (TAMs), which are immunosuppressive cells that promote tumor growth and metastasis. By depleting or reprogramming these macrophages, IMP4927 aims to enhance anti-tumor immunity and improve the efficacy of checkpoint inhibitors or other immunotherapies.
