Official title

Adjunctive Intravenous Ascorbic Acid for Advanced Non-Small Cell Lung Cancer: A Double Blind, Placebo Controlled, Phase II Randomized Controlled Trial

Overview

This is a two arm RCT evaluating the effect of intravenous vitamin C versus placebo in patients with incurable non-small cell lung cancer. Participants in both arms will be receiving platinum doublet chemotherapy with or without concurrent immunotherapy as standard care. We plan to enroll 90 patients over 5 years.

Interventions

  • Drug Ascorbic acid
    High dose ascorbic acid delivered intravenously
  • Other Normal Saline
    0.9% NaCl solution

Primary outcome measures

  • Change in Quality of Life [Time frame: Baseline, Chemo cycles 1-4, 6 months, 12 months]
Secondary outcome measures (8)
  • Chemotherapy-Related Toxicities [Time frame: 12 months]
  • Frequency of Discontinuation of Chemotherapy [Time frame: 6 months]
  • Change in General Symptom Burden [Time frame: Baseline, chemo cycles 1-4, 6 months, 12 months]
  • Change in C-Reactive Protein Levels [Time frame: Baseline, chemo cycles 1-4, 6 months, 12 months]
  • Tumour Progression [Time frame: 12 months]
  • Survival [Time frame: 24 months]
  • Safety [Time frame: 6 months]
  • Cytotoxicity [Time frame: 12 months]

Eligibility criteria

Inclusion criteria

  • Adults (≥18 years of age) seen at TOHCC with stage IIIB or IV primary non-small cell lung cancer

  • History of severe renal dysfunction or hemochromatosis
  • Previously undergone cytotoxic chemotherapy or immunotherapy within 12 months prior to randomization
  • If pregnant or planning to become pregnant: not a carrier of the gene for G6PD deficiency
  • Currently taking an investigational product or participation in an investigational study within the past 30 days
  • Any reason which, under the discretion of the Principal Investigator or delegate, would preclude the patient from participating
