Full study description
brief Summary
This study evaluates ADCT-301 in patients with Selected Advanced Solid Tumors. Patients will participate in a Treatment Period with 3-week cycles and a Follow-up Period every 12 weeks for up to 1 year after treatment discontinuation.
detailed Description
This is a Phase 1b, multi-center, open-label study with a dose-escalation part and a dose expansion part. The duration of the study participation for each participant was defined as the time from the date of signed written informed consent to the completion of the followup period, withdrawal of consent, loss to follow-up, or death, whichever occurs first. The study was include a Screening Period (of up to 21 days), a Treatment Period (with cycles of 3 weeks for a Q3W dosing regimen), and a Follow-up Period (approximately every 12 week visits) for up to 1 year after treatment discontinuation.
