Subject has a significant history of renal, neurologic, psychiatric, pulmonary, endocrinologic, metabolic, immunologic, cardiovascular, or hepatic disease that, in the opinion of the Investigator, would adversely affect his/her participation in this study. Any other medical or social condition deemed by the investigator to be likely to interfere with a subject's ability to participate in the study, place the subject at unacceptable risk or interfere with the interpretation of the results. For subjects who have required surgical intervention for any above diseases within the past 6 months, a discussion with the Investigator and the Medical Monitor is needed. 6.

Arms

Experimental: Dose Escalation Phase

Phase 1a dose-escalation will begin with group 1 and proceed until DLT is observed and MTD is established, or until an RP2D is established. Subjects enrolled in the dose cohorts will follow the 3+3 study design, starting with an accelerated step-up dosing schedule (with a starting dose of 20 mg, 50 mg, 100 mg once daily) until they reach the designated target dose (50 mg, 100 mg, 200 mg, 300 mg, 400 mg, 500 mg, 600 mg, 800 mg). Once the MTD or RP2D is established for group 1, the phase 1a dose escalation can proceed for group 2. The starting dose level for group 2 will be one dose level below the MTD or RP2D established for group 1.

Experimental: Dose Expansion Phase

Additional subjects will be recruited to further explore the safety, tolerability, PK, and efficacy in specific subject subgroups. One or more RP2D may be explored. Definition of these cohorts will be accomplished by protocol amendment, and in light of emerging data from Phase 1a.
