Trial of the Effects of Intravenous GC4419 on the Incidence and Duration of Severe Oral Mucositis (OM) in Patients with Locally Advanced, Non-Metastatic Squamous Cell Carcinoma of the Oral Cavity or Oropharynx.

What we are studying

You have been asked to take part in this study because you have been diagnosed with a specific type of cancer called squamous cell carcinoma of the head and neck (SCCHN) and are receiving a standard treatment (radiation therapy and chemotherapy) for your cancer. As a result of your radiation therapy, you may develop soreness, irritation, and ulcers in your mouth and may have a hard time eating, drinking, and/or swallowing. This problem or condition is called “oral mucositis.” This study will involve treatment with an investigational drug called GC4419. Investigational means that the study drug has not been approved by the U.S. Food and Drug Administration (FDA) for sale in the United States and will not be approved until tests show that the study drug is safe and effective. GC4419 is an investigational drug that is being tested to prevent or decrease mouth pain and oral mucositis, which can be caused by cancer treatment.
