Rapamycin Therapy in Head and Neck Squamous Cell Carcinoma

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01195922
Recruitment Status : Completed
First Posted : September 6, 2010

Brief Summary:


- Advanced-stage head and neck cancer (head and neck squamous cell carcinoma [HNSCC]) has moderately successful treatment outcomes, usually involving surgery as part of the standard treatment. Researchers are investigating the use of the drug rapamycin to prevent tumor growth in HNSCC, and are interested in using it to treat individuals with HNSCC that has not been treated previously with other drugs, radiation, or surgery.


- To evaluate the usefulness of rapamycin in decreasing tumor size prior to surgery for head and neck squamous cell carcinoma.


- Individuals at least 18 years of age who have been diagnosed with advanced head and neck squamous cell carcinoma that has not yet been treated.


  • Participants will be screened with a physical examination, medical history, blood tests, and imaging studies.
  • Approximately 1 month before scheduled surgery, participants will begin to receive rapamycin. Participants will take rapamycin once daily for 21 days, followed by a 7-day period without the drug.
  • During the 21-day rapamycin treatment, participants will have weekly study visits to provide blood and urine samples and have possible tumor biopsies and imaging studies such as x-rays or tumor photographs. Participants will have additional study visits for tests 1 day and 1 week after the end of rapamycin treatment, followed by HNSCC surgery.
  • Participants will have a final visit to provide blood samples 30 days after surgery.
  • Participants medical records will be reviewed 1 year after surgery; however, participants will not need to have further study visits at this time.

  2. Percent (%) Changes in Tumor Size, Blood Flow, and Standardized Uptake Value [ Time Frame: 21 days post treatment with rapamycin ]
  3. Percent (%) Change in Clinical and Laboratory Evaluations for Safety [ Time Frame: Percent (%) change from Pre to Post treatement (~21 days) ]
