Participant Flow

There were 36 participants enrolled. Of these, 4 from Group I and 1 from Group II did not have evaluable biopsies and were considered not evaluable. Data only reflect the evaluable population (15 from Group I and 16 from Group II).

Participant milestones

Participant milestones
Measure
Biomarker Evaluation Group I
Participants who had blood and urine samples collected at Visit 1. After allocation, punch skin biopsies, plucked hair samples, blood, and urine were collected at baseline, and at 24 and 48 hours post dosing with cytotoxic agent(s). An additional sample collection at 32 hours may have been performed if deemed necessary after review of the data.
Biomarker Evaluation Group II
A second group of participants who had blood and urine samples collected at Visit 1 (there was no baseline). After allocation, punch skin biopsies, plucked hair samples, blood, and urine were collected at at 24, 32 and 48 hours post dosing with cytotoxic agent(s).
