Purpose
The purpose of the trial is to determine the maximum tolerated dose and to establish the
safety profile of HuMax-AXL-ADC in a mixed population of patients with specified solid tumors
Detailed Description
The trial consists of two parts; a dose escalation part (phase I, first in- human (FIH)) and
an expansion part (phase IIa).
The dose escalation part has two dose escalation arms: the first arm investigates a once
every 3 weeks (1Q3W) dosing schedule and the second arm investigates a three administrations
over 4 weeks (3Q4W) dosing schedule.
The Expansion part of the trial will further explore the recommended phase 2 dose and dosing
regimens of HuMax-AXL-ADC as determined in Part 1
