A Trial of the Effects of Intravenous GC4419 on the Incidence and Duration of Severe Oral Mucositis (OM) in Patients Receiving Post-Operative or Definitive Therapy with Single-Agent Cisplatin plus IMRT for Locally Advanced, Non-Metastatic Squamous Cell Carcinoma of the Oral Cavity or Oropharynx

Study Summary

  • As part of this study, the patient will receive a new treatment aimed at reducing the risk of oral mucositis (OM). OM is a common side effect of patients receiving radiation and/or chemotherapy to the oral cavity. OM is the breakdown of tissue in the mouth leading to open sores and debilitating pain. At any time in treatment, patients receiving this particular treatment have around a 66{1f271575cd6051458901182c7c4c4f48bdfabd4170eb34ee1127140158f2ee5c} chance of developing severe OM (WHO Grade 3-4).

  • Patients will come in daily to receive study drug through IV, then receive radiation. Once a week, patients will receive chemotherapy. The treatment will last for 7 weeks.
  • The goal this new treatment is to not only reduce overall incidence of OM in these patients but also to reduce the overall time that a patient would be suffering from OM and also delay the initial onset of OM.
  • This trial is double-blinded, which means we will not know if you receive the treatment or a placebo.  The chances of receiving treatment are 2:1.
  • About 200 people will take part in this research study
