New Approach of Assessing Drug Response for Treatment of Nasopharyngeal Cancer

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: NCT01365208

Brief Summary:
The combination of pEBV DNA (half-life) and PET-CT following 1 course of chemotherapy allow earlier and more detection of drug response in advanced NPC than RECIST method, in patients with previously untreated advanced NPC who will receive platinum-based chemotherapy. This study will also determine if this new method can predict survival in these patients. This study may have far-reaching impact on drug development in NPC as it may offer a more optimal way of evaluating drug efficacy in clinical trials and also in clinical management.

Group/Cohort Intervention/treatment
advanced nasopharyngeal carcinoma Drug: Chemotherapy
platinum-based chemotherapy

Primary Outcome Measures :
  1. To determine if measuring tumor metabolic response during chemotherapy can predict survival [ Time Frame: 3 years ]
  2. To determine if measuring plasma EBV DNA (half-life) early during chemotherapy can predict survival [ Time Frame: 3 years ]

Secondary Outcome Measures :
  1. New method of assessing drug response (measuring tumor metabolic response via FDG-PET & plasma EBV DNA (half-life) after 1 course of chemotherapy) can better predict survival, than the conventional method [ Time Frame: 3 years ]
  2. To determine if plasma EBV DNA (half-life) correspond with best response rate based on the conventional 'Response Evaluation Criteria in Solid Tumors' - RECIST criteria. [ Time Frame: 3 years ]
  3. overall survival [ Time Frame: 3 Years ]
  4. progression free survival [ Time Frame: 3 Years ]
