Announcement
Genmab A/S announced today that data from the Phase 2 innovaTV 207 trial (NCT03485209) Part C (n=40), investigating tisotumab vedotin, an antibody-drug conjugate directed to tissue factor, demonstrated encouraging antitumor activity as a monotherapy in patients with head and neck squamous cell carcinoma (HNSCC) who experienced disease progression on or after first-line therapy.
AI Summary
Genmab A/S reported encouraging results from Part C of its Phase 2 innovaTV 207 trial (NCT03485209) investigating tisotumab vedotin, an antibody‐drug conjugate, in patients with head and neck squamous cell carcinoma (HNSCC). In this trial, 40 patients who experienced disease progression after first-line therapy received tisotumab vedotin monotherapy. The study demonstrated a confirmed objective response rate of 32.5%, with one patient achieving a complete response and 12 showing a partial response. The median duration of response was 5.6 months, and many patients saw a response as early as 1.4 months. These promising findings were presented at the 2024 ASCO® Annual Meeting in Chicago and suggest that tisotumab vedotin could provide a potential new treatment option for HNSCC patients after standard platinum-based therapy has failed.
