EGFR and COX-2 are involved in tumorigenesis, angiogenesis and metastases and are frequently over expressed in NPC.COX-2 and EGFR inhibitors are active in NPC.There is synergistic action between COX-2 and EGFR inhibitors.

Study hypothesis: Celecoxib and gefitinib can reduce angiogenesis and induce anti-tumorigenicity in patients with nasopharngeal cancer.

Primary Outcome Measures:
  • To study histopathological changes in tumor following inhibition with celecoxib and gefitinib. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • To evaluate the safety profile of celecoxib and ZD1839. [ Time Frame: 30 days ]
  • To assess the pharmacokinetics of ZD1839 and celecoxib. [ Time Frame: 30 days ]

Enrollment: 22
Study Start Date: November 2003
Study Completion Date: January 2009
Primary Completion Date: March 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Celecoxib and ZD1839
Celecoxib and ZD1839 will be given twice a day and daily respectively for two consecutive weeks prior to further anti-cancer treatment.
Drug: celecoxib, gefitinib
The dose of ZD1839 to be administered is 250mg. ZD1839 will be taken once daily in the morning at approximately the same time each day. If the patient inadvertently did not take the dose in the morning, the patient may take that dose anytime up to 10pm that same day. The daily treatment will be resumed the next day at the scheduled morning dose. Celecoxib will be administered at 400 mg bd.
Other Name: ZD1839 (Iressa™)


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Histologically proven NPC.
  2. Any clinical stage NPC as defined by the AJCC/UICC System.
  3. No prior radiotherapy, chemoradiotherapy, immunotherapy or investigational agents.
  4. No prior NSAIDs or corticosteroids for at least 4 weeks.
  5. ECOG performance status ≤ 2.
  6. Adequate end organ function
  7. Life expectancy > 3 months.
  8. Signed informed consent -

Exclusion Criteria:

  1. Inability to take celecoxib and gefitinib for the specified period of time (14 days) prior to definitive therapy.
  2. Tumor not visible on fibre nasopharyngoscopy for biopsy.
  3. Known peptic ulcer disease.
  4. Evidence of clinically active interstitial lung disease.
  5. Previous or concomitant malignancies with the exception of adequately treated carcinoma-in-situ of the cervix and basal or squamous cell carcinoma of the skin.
  6. Women who are pregnant or lactating. Females with child-bearing potential must have a negative serum pregnancy test within 7 days prior to study enrolment.
  7. Women of childbearing potential who are not practising adequate contraception.
  8. Concurrent medical problems that would significantly limit compliance with the study.
  9. Presence of any underlying medical conditions (eg. Unstable or uncompensated respiratory, cardiac, renal or hepatic disease) that in the opinion of the investigator would make the patient unsuitable for study participation.
  10. Known hypersensitivity to celecoxib and gefitinib or any of the excipients of the products, known sulphonamide sensitivity and allergic reaction following the ingestion of NSAIDs.
  11. Known HIV, HBV or HCV infection. -
