There are 2 parts to this study: Part 1 and Part 2. This consent form is for Part 1 only. In Part 1, there are 3 sub-groups: Part 1A, 1B, and 1C. The goal of this clinical research study is to find the highest tolerable dose of M4112 that can be given to patients with advanced or metastatic (have spread) solid tumors that are unresectable (cannot be removed with surgery). In this study, M4112 will be studied alone (Part 1A) or in combination with either avelumab (Part 1B) or M7824 (Part 1C). This is the first study using M4112 in humans. The safety of M4112 and the drug combinations will also be studied.
