First-in-human, Dose-escalating Safety Study of Tissue Factor Specific Antibody Drug Conjugate Tisotumab Vedotin (HuMax® TF ADC) in Patients With Locally Advanced and/or Metastatic Solid Tumors Known to Express Tissue Factor

The purpose of the trial is to establish the tolerability of HuMax-TF-ADC in a mixed population of patients with specified solid tumors.

Study Overview

Detailed Description

The study is conducted in two parts. The dose escalation portion of the trial subjects are enrolled into cohorts at increasing dose levels of HuMax-TF-ADC in 21 day treatment cycles.
