Brief Summary:
This trial was to explore whether intravenous vitamin C can prolong resistance time of Tyrosine Kinase Inhibitor(TKI) on lung adenocarcinoma patients with Epidermal Growth Factor Receptor(EGFR) mutations, and can benefit NSCLC patients.

Condition or disease Intervention/treatment Phase
Carcinoma, Non-Small-Cell Lung Drug: Vitamin C Drug: Tyrosine kinase inhibitor Phase 1 Phase 2

Detailed Description:

The effects of vitamin C in combination with tyrosine kinase inhibitor on tumor size, tumor markers, inflammatory factor levels, quality of life, duration of resistance, progression-free survival, and overall survival time were evaluated.

This trial is a low risk treatment, and has developed the appropriate safety measures and contingency plans to ensure patients' safety in the whole process.

Patients will be followed up after the end of the trial, and follow-up observations will be performed every month during the first year. Followed every 3 months in the second year for 3 years.

Official Title: Clinical Outcomes of Intravenous Vitamin C Synergy With Tyrosine Kinase Inhibitor in Lung Adenocarcinoma Patients With Epidermal Growth Factor Receptor Mutations
Actual Study Start Date : December 5, 2018
Estimated Primary Completion Date : December 31, 2020
Estimated Study Completion Date : December 31, 2022


Arm Intervention/treatment
Experimental: Experimental group
75 patients received a weekly intravenous Vitamin C injection (dose: 30 g / time, once a week, treatment termination when the disease progress is confirmed) in combination with daily taking tyrosine kinase inhibitor.
Drug: Vitamin C
Participants will receive intravenous vitamin C therapy at the indicated dose.
Other Name: Sodium Ascorbate

Drug: Tyrosine kinase inhibitor
Participants will receive Tyrosine kinase inhibitor therapy in cycles: continuous treatment at the indicated dose.

Experimental: Control group
75 patients received tyrosine kinase inhibitor daily. (dose: Osimertinib 80 mg/d, or Tarceva 150 mg/d, or Iressa 0.25 g/d.)
Drug: Tyrosine kinase inhibitor
Participants will receive Tyrosine kinase inhibitor therapy in cycles: continuous treatment at the indicated dose.




Primary Outcome Measures :
  1. Progression free survival [ Time Frame: From the start date of treatment until the date of first documented progression or death, assessed up to 2 years ]
    From the start of treatment until the patient has tumor progression or death


Secondary Outcome Measures :
  1. Overall survival [ Time Frame: From the start date of treatment until the date of death from any cause, assessed up to 2 years. ]
    The length of time from the start of treatment for a disease until death


Other Outcome Measures:
  1. Changes in Health Related Quality of Life: European Organisation for Research and Treatment of Cancer(EORTC) quality of life questionnaire(QLQ)-C30 [ Time Frame: From the start date of treatment until the date of first documented progression or death, assessed up to 2 years ]
    Using QLQ-C30: Function subscales, (include physical, role, emotional, cognitive, social, global) (averaged, 0-100, higher value represent a better outcome); Symptoms subscales (include fatigue, nausea, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea) (averaged, 0-100, lower value represent a better outcome). Given at basal, 1, 2, 3, 6, 12 months.
