New Approach of Assessing Drug Response for Treatment of Nasopharyngeal Cancer

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.

Condition Intervention
Advanced Nasopharyngeal Carcinoma
Drug: Chemotherapy

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Prospective Evaluation of Plasma EBV DNA Half-life and PET-CT Scanning as a New Tool in Assessing Early Response to Chemotherapy in Patients With Advanced Nasopharyngeal Carcinoma

Further study details as provided by Chinese University of Hong Kong:

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

Secondary Outcome Measures:
  • 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 ]
  • 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 ]
  • overall survival [ Time Frame: 3 Years ]
  • progression free survival [ Time Frame: 3 Years ]
