Study of ADCT-301 in Patients With Selected Advanced Solid Tumors
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 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.
These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

A TEAE is defined as an AE that occurs or worsens in the period extending from the first dose of study drug to 30 days after the last dose of study drug in this study or start of a new anticancer therapy, whichever is earlier. Any clinically significant changes from baseline in the safety laboratory values, vital signs, 12-lead electrocardiogram (ECG), and Eastern Cooperative Oncology Group (ECOG) performance status were reported as TEAEs. | Up to 3 years |
Number of Participants Who Experienced TEAEs by Common Terminology Criteria for Adverse Events (CTCAE) Grade | AEs were graded according to CTCAE v4.0 (or more recent). For events not included in the CTCAE criteria, the severity of the AE was graded on a scale of 1 to 5, where 1 is asymptomatic or mild symptoms, 2 is moderate, 3 is severe, 4 is Life-threatening consequences and 5 is death related to an AE. | Up to 3 years |
Number of Participants Who Experienced Treatment-emergent Serious Adverse Events (SAEs) | A SAE is defined as any AE that results in death, is life threatening, requires inpatient hospitalization or prolongation of existing hospitalization (hospitalization for elective procedures or for protocol compliance is not considered an SAE), results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect or important medical events that do not meet the preceding criteria but based on appropriate medical judgement may jeopardize the participant or may require medical or surgical intervention to prevent any of the outcomes listed above. | Up to 3 years |
Number of Participants Who Experienced a SAE by CTCAE Grade | AEs were graded according to CTCAE v4.0 (or more recent). For events not included in the CTCAE criteria, the severity of the AE was graded on a scale of 1 is mild or asymptomatic, 2 is moderate, 3 is severe, 4 is Life-threatening and 5 is death related to an AE. | Up to 3 years |
Number of Participants Who Experienced a Dose Interruption | Dose interruption for participants treated with ADCT-301 as monotherapy and for participants treated with ADCT-301 in combination with pembrolizumab. | Up to 3 years |
