Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to learn if KQB365 works to treat advanced solid tumor cancer in adults. It will also learn about the safety of KQB365. The main questions it aims to answer are:

* What is the safe dose of KQB365 by itself or in combination with cetuximab?
* Does KQB365 alone or in combination with cetuximab decrease the size of the tumor?
* What happens to KQB365 in the body?

Participants will:

* Receive KQB365 infusion weekly alone or in combination with cetuximab
* Visit the clinic about 9 times in the first 6 weeks, and then once every week after that.
