Genmab A/S has reported favourable data in cervical cancer for its experimental antibody-drug conjugate (ADC), tisotumab vedotin, that it is developing with Seattle Genetics Inc. In a Phase 2 trial, the drug achieved a 24% objective response rate in patients with metastatic disease, with a median duration of response of 8.3 months. This compares with an objective response rate of less than 15% and a median overall survival of six to 9.4 months for standard treatments, the company said on 29 June.
