Study Summary

Isunakinra - a potent Interleukin-1 receptor inhibitor - will be given to patients with solid tumors to determine safety and tolerability of three different doses. Isunakinra will then be combined with a PD-(L)1 inhibitor. Pharmacokinetics and Pharmacodynamic effects of monotherapy treatment as well as the combination will be evaluated.

Primary Outcome
