Detailed Description

The main questions this clinical trial aims to answer are: - What, if any, are the side effects of different dose levels in humans? - What is the maximum tolerated dose? - How does the human body process the drug? - Does the drug slow, stop or eliminate cancer in human participants? Participants will be asked to: - provide informed consent - be evaluated by physicians and provide laboratory specimens to determine if eligible - take MBQ-167 orally twice a day for at least 21 days - may continue dosing, if safe to do so, until not effective or other decision to stop is made - participate in multiple visits that include additional evaluations, laboratory tests and diary review until after stopping the investigational drug
