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.
This is a Phase 1b, multi-center, open-label study with a dose-escalation part and a dose
The duration of the study participation for each patient is defined as the time from the date
of signed written informed consent to the completion of the follow-up period, withdrawal of
consent, loss to follow-up, or death, whichever occurs first.
The study will 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
