Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Newly diagnosed stage IIIB or IV non-small cell lung cancer with no prior first-line cytotoxic therapy
At least 18 years of age
Must not have
Uncontrolled intercurrent illness including symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements

Awards & highlights


This trial is testing whether adding high-dose vitamin C to the standard treatment for non-small cell lung cancer will improve outcomes.

Who is the study for?
Adults with newly diagnosed stage IIIB or IV non-small cell lung cancer who haven't had first-line cytotoxic therapy. They must have certain blood counts within normal ranges, be able to tolerate a vitamin C test dose, and not be pregnant or breastfeeding. Those with treated and stable brain metastasis can join; however, individuals with specific health conditions or on certain medications are excluded.Check my eligibility
What is being tested?
The trial is testing the addition of high-dose ascorbate (vitamin C) to standard chemotherapy treatments Paclitaxel and Carboplatin for non-small cell lung cancer. All participants will receive this combination to see if it improves treatment outcomes.See study design
What are the potential side effects?
High-dose vitamin C may cause side effects such as digestive discomfort, headache, fatigue, or skin reactions. Chemotherapy drugs like Paclitaxel and Carboplatin can lead to hair loss, nerve damage, nausea, low blood counts increasing infection risk.

Other Research
The most common treatments for Non-Small Cell Lung Cancer (NSCLC) include chemotherapy, targeted therapy, immunotherapy, and high-dose ascorbate. Chemotherapy works by killing rapidly dividing cells, including cancer cells, but can also affect healthy cells, leading to side effects. Targeted therapies, such as EGFR inhibitors, specifically target molecular abnormalities in cancer cells, minimizing damage to normal cells. Immunotherapy, including PD-1/PD-L1 inhibitors, boosts the body's immune system to recognize and destroy cancer cells. High-dose ascorbate (vitamin C) acts as a pro-oxidant, generating hydrogen peroxide to induce cytotoxicity selectively in cancer cells. This is significant for NSCLC patients as it offers a potential treatment that can enhance the efficacy of conventional therapies while potentially reducing their side effects.
