The study has 2 parts. Part A is a dose escalation portion where the patients will be doses every three weeks following an accelerated 3+3 design. This portion will enroll approximately 25 patients with locally advanced or metastatic cancers. Part B is an expansion portion where approximately 30 additional patients will be dosed at the recommended dose level every 3 weeks.

The trial will last approximately 2 years, with assessments including safety labs, ECGs, PKs and PDs and CT/MRI tumor assessments, based on the Q3W dosing schedule.
