About this study
Official title: Phase Ⅲ Study of IV Ascorbic Acid in Combination With XELOX vs Treatment With XELOX Alone as First-line Therapy for Advanced Gastric Cancer
Linus Pauling and Dr Ewan Cameron have published two retrospective studies about using high dose vitamin C to treat cancer patients forty years ago. Their studies have shown that high dose vitamin C usage could significantly prolong overall survival of patients with advanced cancer. Recently, preclinical study has shown that human colorectal cancer cells harboring KRAS or BRAF mutations are selectively killed by high levels of ascorbic acid (AA). High dose of AA impairs tumor growth in Apc/KRASG12D mutant mice. Previous phaseⅠclinical trials have found that high dose (1.5g/kg or 90g/m2) iv AA is well tolerated in cancer patients. This protocol is a phase Ⅲ, study of ascorbic acid (AA) infusions combined with treatment with mFOLOX6 versus mFOLOX6 alone as first-line therapy in patients with recurrent or advanced gastric cancer.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression Free Survival
Time-to-event outcome measure (initial disease progression) measured in days from cycle 1 day 1 to day of first progression as defined by RECIST1.1 criteria from NCI
Measured: up to 5 years
Secondary outcomes (2)
Overall Survival
Time to event outcome measure (death), measured in days from cycle 1 day 1
Measured: up to 5 years
Response Rate
To utilize CT or PET/CT scans to assess overall tumor response rate (complete and partial response) and evaluate disease progression in subjects with advanced or recurrent RAS mutant colorectal cancer treated with the combination of ascorbic acid and FOLOX/FORFIRI +/- bevacizumab versus treatment with FOLFOX/FORFIRI +/- bevacizumab alone
Measured: up to 5 years

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing ascorbic acid and mFOLFOX6 in people with Gastric Cancer, run by Sun Yat-sen University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 18 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Feng Wang, MD.,PhD. (+862087343795, wangfeng@sysucc.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression Free Survival (time frame: up to 5 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2017.
