Additional Study Information: The purpose of this research is to determine the dose and dosing regimens of an investigational drug, MBRC-101, that are well tolerated, as well as to evaluate its safety in patients with advanced or metastatic solid tumors that have already received conventional therapy. MBRC-101 is not an approved treatment anywhere in the world. Investigational means that the drug has not been approved by any government authority responsible for the regulation of new medicines, such as the U.S. Food and Drug Administration (FDA). This is the first time MBRC-101 is being tested in humans.
