ADG206: All participants in this study will receive the study drug ADG206 in one of the designed dosage level. ADG206 will be administered by intravenous infusion over 60-90 minutes on Day 1 of each treatment cycle until disease progression, intolerable toxicities or withdrawal of consent, or up to 2 years.
