Currently study will only be enrolling the Phase 1b and the Phase 2a protocol requirements will be added to the study near completion of the Phase 1b

The goal of this interventional study is to test a new monoclonal antibody, called MAQ-001, as a potential treatment for certain types of advanced cancers in different organs or compartments, such as skin, lung, kidney, liver, stomach, bowel, the female reproductive system, and hematology lymph node cancers. The main question[s] it aims to answer are:
* the best dose of MAQ-001 that is safe to use alone or in combination with another anti-cancer medicine ipilimumab;
* how MAQ-001 works in the body and how it affects the whole cancer and its cells.
Participants will:
* receive a defined dose of MAQ-001 or MAQ-001 in combination with ipilimumab (depending on rank of enrolment) on day 1 of a 21-day cycle, for a maximum of 2 years.
* receive safety examinations and tumor assessment
* donate blood and other biological materials for safety and pharmacokinetic evaluation
