100P Immunotherapy around the clock: Impact on stage IV melanoma

Immunotherapy is currently the standard of care in the treatment of metastatic melanoma. Immune cells in the tumor microenvironment play a decisive role in tumor growth and response to therapy. NK and dendritic cells, monocytes, T and B lymphocytes exhibit circadian oscillations in the peripheral blood, as well as PD-L1 expression. Recent data from MEMOIR study suggests the effectiveness of immune checkpoint inhibitors in melanoma is lower when more than 20% of infusions are in the late afternoon.
