  • Dose Limiting Toxicities (DLTs) [ Time Frame: Dose Limiting Toxicities will be assessed from first treatment cycle (3 or 4 weeks) ]
    As this is a phase I trial the main objective is to assess the recommended phase 2 dose of enapotamab vedotin (HuMax-AXL-ADC)
  • Adverse events (AEs) [ Time Frame: At end of trial (up to 24 months) ]
    As this is a phase I trial the main objective is to assess the safety and tolerability of enapotamab vedotin (HuMax-AXL-ADC) throughout the treatment periods of the patients participating in the trial.

Descriptive Information
Brief Title  ICMJE Enapotamab Vedotin (HuMax-AXL-ADC) Safety Study in Patients With Solid Tumors
Official Title  ICMJE First-in-human, Open-label, Dose-escalation Trial With Expansion Cohorts to Evaluate Safety of Axl-specific Antibody-drug Conjugate (Enapotamab Vedotin, HuMax®-AXL-ADC) in Patients With Solid Tumors
Brief Summary 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
