Cilengitide in Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck (SCCHN)

• Status: Completed
• Trial end date: 2013-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this open-label, randomized, controlled, Phase 1/2 study of the integrin inhibitor cilengitide is to evaluate the safety and efficacy of the combination of different regimens of cilengitide added to cisplatin, 5-fluorouracil (5-FU), and cetuximab in participants with recurrent/metastatic squamous cell carcinoma of the head and neck (SCCHN).

The Phase 1 part was conducted in dedicated study centers. In the Phase 2 part of this trial, cilengitide is administered at two different doses to two experimental groups. The third group will only receive cisplatin, 5-FU and cetuximab. In the Phase 1 part of this trial, the dose of cilengitide in combination with cisplatin, 5-FU and cetuximab was determined.

Cilengitide is an experimental anti-cancer substance interacting with so-called integrins. Integrins are protein molecules that are known to be present on the surface of certain cancer cells. Integrins are also found on certain cells that belong to growing blood vessels (endothelial cells). Integrins potentially facilitate the blood vessels' support of the tumor (angiogenesis) as well as the tumor's growth and further spread throughout the body (metastasis). By inhibiting integrins on the tumor cell surface, cilengitide potentially kills cancer cells, and potentially sensitizes cancer cells to other co-administered therapeutics. By inhibiting integrins on the endothelial cell surface, it potentially inhibits the ingrowth of additional blood vessels towards the tumor.

Cilengitide is given as an intravenous infusion (given by a drip in one vein of your arm). If any unacceptable side effect occurs, treatment with the study drug will be stopped.
