The cytokine interleukin-18 (IL-18) has immunostimulatory effects but is negatively regulated by a secreted binding protein, IL-18BP, that limits IL-18's anti-cancer efficacy. A "decoy-resistant" form of IL-18 (DR-18), that avoids sequestration by IL-18BP while maintaining its immunostimulatory potential, has recently been developed. Here, we investigated the therapeutic potential of DR-18 in renal cell carcinoma (RCC).

Thus, there is increasing need for alternative immunomodulating agents. The co-inhibitory molecule T-cell immunoglobulin and ITIM domain (TIGIT) may play a role in resistance to approved immune checkpoint inhibitors and is being investigated as a potential therapeutic target.

Drugs or cellular products that bind to gp100 are being investigated for treatment of cutaneous melanoma. The relative specificity of gp100 expression in melanocytes makes it an attractive target to harness for therapeutic intent. For example, Tebentafusp, a bispecific gp100 peptide-HLA-directed CD3 T cell engager, has generated significant enthusiasm in recent years due to its success in improving outcomes for uveal melanoma and is being studied in cutaneous melanoma.
