Individualized Treatment in Treating Patients With Stage II-IVB Nasopharyngeal Cancer Based on EBV DNA

NCT02135042

Description:

There are two study questions we are asking in this randomized phase II/III trial based on a blood biomarker, Epstein Barr virus (EBV) deoxyribonucleic acid (DNA) for locoregionally advanced non-metastatic nasopharyngeal cancer. All patients will first undergo standard concurrent chemotherapy and radiation therapy. When this standard treatment is completed, if there is no detectable EBV DNA in their plasma, then patients are randomized to either standard adjuvant cisplatin and fluorouracil chemotherapy or observation. If there is still detectable levels of plasma EBV DNA, patients will be randomized to standard cisplatin and fluorouracil chemotherapy versus gemcitabine and paclitaxel. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin, fluorouracil, gemcitabine hydrochloride, and paclitaxel work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving cisplatin and fluorouracil is more effective than gemcitabine hydrochloride and paclitaxel after radiation therapy in treating patients with nasopharyngeal cancer.

Detailed Description

      PRIMARY OBJECTIVES:

      I. To determine whether substituting adjuvant concurrent high dose cisplatin (CDDP) and
      fluorouracil (5-FU) with gemcitabine (gemcitabine hydrochloride) and paclitaxel will result
      in superior progression-free survival. (Detectable Plasma Epstein Barr Virus [EBV]
      Deoxyribonucleic Acid [DNA] Cohort randomized Phase II) II. To determine whether omitting
      adjuvant CDDP and 5-FU (observation alone in the adjuvant setting) will result in
      non-inferior overall survival as compared with those patients receiving adjuvant CDDP and
      5-FU chemotherapy. (Undetectable Plasma EBV DNA Cohort Phase III)

      SECONDARY OBJECTIVES:

      I. Time to distant metastasis. (Randomized Phase II and Phase III) II. Time to local
      progression. (Randomized Phase II and Phase III) III. Time to regional progression.
      (Randomized Phase II and Phase III) IV. Progression-free survival (Undetectable Cohort). V.
      Overall survival (Detectable Cohort). VI. Acute and late toxicity profiles based on
      clinician-reported Common Terminology Criteria for Adverse Events (CTCAE), version (v.) 4.
      (Randomized Phase II and Phase III) VII. Death during or within 30 days of end of protocol
      treatment. (Randomized Phase II and Phase III) VIII. Quality of life (general and physical
      well-being). (Randomized Phase II and Phase III) IX. Quality of life (hearing). (Randomized
      Phase II and Phase III) X. Quality of life (peripheral neuropathy). (Randomized Phase II and
      Phase III) XI. Cost effectiveness. (Randomized Phase II and Phase III)

      OUTLINE:

      Patients undergo intensity modulated radiation therapy (IMRT) once daily (QD) 5 days a week
      for 6.5 weeks and receive low-dose cisplatin intravenously (IV) over 30-60 minutes once
      weekly during IMRT. Beginning 1 week after chemoradiation, plasma samples are collected for
      EBV DNA analysis.

      PHASE II: Patients with detectable EBV DNA from pre-treatment analysis are randomized to 1 of
      2 treatment arms.

      ARM I: Patients receive PF regimen comprising cisplatin IV over 60-120 minutes and
      fluorouracil IV over 96 hours continuously beginning at least 4 weeks after completion of
      IMRT. Treatment repeats every 28 days for 3 courses in the absence of disease progression or
      unacceptable toxicity.

      ARM II: Patients receive GT regimen comprising paclitaxel IV over 1 hour and gemcitabine
      hydrochloride IV over 30 minutes on days 1 and 8 at least 4 weeks after completion of IMRT.
      Treatment repeats every 21 days for 4 courses in the absence of disease progression or
      unacceptable toxicity.

      PHASE III:

      Patients with undetectable EBV DNA from pre-treatment analysis are randomized to 1 of 2
      treatment arms.

      ARM III: Patients receive PF regimen as in Arm I.

      ARM IV: Patients undergo clinical observation.

      After completion of study treatment, patients are followed up every 4 months for 2 years,
      every 6 months for 3 years, and then annually thereafter.

Primary Outcome Measures

Measure:Overall survival (OS) (Undetectable Plasma EBV DNA Cohort Phase III)
Time Frame:Up to 7 years
Safety Issue:
Description:Estimated using the Kaplan-Meier method for each arm. Their distributions will be compared between treatment arms with a 1-sided log rank test. The confidence interval approach will be used for the final analysis of OS.

Secondary Outcome Measures

Measure:Changes in pure tone audiometry (Phase II and III)
Time Frame:Baseline to up to 1 year
Safety Issue:
Description:Correlation between categorical measures will be summarized by odds ratios, chi-square tests, and associated measures. Adjusted correlation may be derived from analysis of covariance (ANCOVA) models or derived directly using nonparametric analysis of variance (ANOVA) models if normality assumption is violated. Correlations between HHIE-S PRO scores and PTA and FACT-NP hearing, and PTA will be compared as dependent statistics
Measure:Changes in QOL (hearing) as assessed by the Hearing Handicap Inventory for the Elderly-Screening version (HHIE-S) (Phase II and III)
Time Frame:Baseline to up to 24 months
Safety Issue:
Description:QOL analysis including overall score and change from baseline will be summarized using mean and standard deviation at each time point for each arm. Overall and nasopharyngeal-specific QOL, hearing QOL (FACT-NP hearing domain, HHIE-S scores), peripheral neuropathy QOL over the short and long term and pure-tone audiometry (PTA) scores will be compared using a two sample independent t test and paired t test if the comparison is within the experimental arm between different time points.
Measure:Changes in QOL (peripheral neuropathy) as assessed by the FACT-Taxane (Phase II and III)
Time Frame:Baseline to up to 24 months
Safety Issue:
Description:
Measure:Changes in quality of life (QOL) (general and physical well-being) assessed using the Functional Assessment of Cancer Therapy (FACT)-Nasopharyngeal (NP) (Phase II and III)
Time Frame:Baseline to up to 24 months
Safety Issue:
Description:Changes in patient reported outcome (PRO) scores will be correlated to clearance or non-clearance of EBV titers. Descriptive statistics derived from FACT-NP will be used to enrich the understanding of QOL as it pertains to the 2 phase III arms of observation versus additional adjuvant chemotherapy. Univariable and multivariable analysis will be performed using the Cox proportional hazards model for OS and distant metastasis. Pearson correlation will be estimated between general and physical well-being. QOL measures and change from baseline will be correlated to EBV DNA.
Measure:Cost effectiveness as assessed by the health-related QOL (HRQOL) from the EuroQol (EQ-5D) instrument (Phase II and III)
Time Frame:Up to 24 months
Safety Issue:
Description:Incremental cost effectiveness ratios will be compared to determine the probability of cost effectiveness of various interventions, with sensitivity analyses to identify model weaknesses. The expected value of perfect information will be determined to delimit the upper boundary for cost-effective future investment in this area of research.
Measure:Incidence of acute grade 3-5 adverse events (Phase II and III)
Time Frame:Up to 7 years
Safety Issue:

Measure:Time to distant metastasis (DM) (Phase II and III)
Time Frame:Up to 7 years
Safety Issue:
Description:The cumulative incidence method will be used to estimate local, regional, and distant failure rates. The failure rates for the experimental treatment will be compared against the control using a failure-specific log-rank test. Multivariate analysis will be performed using the Cox proportional hazards model.
Measure:Time to local progression (Phase II and III)
Time Frame:Up to 7 years
Safety Issue:
Description:The cumulative incidence method will be used to estimate local, regional, and distant failure rates. The failure rates for the experimental treatment will be compared against the control using a failure-specific log-rank test. Multivariate analysis will be performed using the Cox proportional hazards model.
Measure:Time to regional progression (Phase II and III)
Time Frame:Up to 7 years
