This is a multicenter, single arm, 3-cohort, open-label trial of high dose Vitamin C intravenous infusion in subjects with solid tumor malignancies who are eligible for resection (cohort A) or with extended RAS (e.g.KRAS or NRAS) or BRAF mutation metastatic cancer who have received prior systemic treatment (cohort B). Cohort C will involve patients with colorectal cancer having an extended RAS or BRAF mutation who are amenable for localregional therapy of hepatic metastases with Yttrium-90 radioembolization.
This clinical trial is for men and women with resectable or metastatic solid tumor malignancies. The objective of the study is to investigate whether high dose vitamin C infusion leads to pathological tumor response in resectable colorectal, pancreatic, and lung cancer (cohort A) or objective tumor response in KRAS or BRAF mutant solid tumors (cohort B). For Cohort C, the primary objective is to determine that maximal tolerated dose of the combination of high dose vitamin C with Y90 radioembolization for patients solid tumor malignancies and liver metastases amenable to local-regional therapy
Patients in cohort A receive a high dose vitamin C infusion for 4 days per week for 2-4 consecutive weeks prior to surgery. Patients in cohort B receive high dose vitamin C infusion for 4 days per week for up to 6 months or disease progression. Cohort C will receive high dose vitamin C for 1-3 weeks. During week 1 vitamin C infusion and Y90 radioembolization of hepatic metastases will occur same day.
A tumor sample will be resected after completion of study drug (high dose vitamin C infusion) treatment to examine the effects of study drug (Cohort A only). In addition, organoids will be grown in vitro and continue to be treated with vitamin C added in culture medium to examine tumor response. The resected tumor in this study will

| Measure | Description | Time Frame |
|---|---|---|
| Pathologic Response Based on Tumor Regression Grading in Cohort A Patients | Number of patients with partial or complete pathological response in surgically resected tumor tissue: Pathological response rate is the number of patients with partial or complete pathological response in surgically resected tumor tissue. Pathologic response was assessed by tumor regression grade. This is a pathologic assessment of the amount of residual cancer cells in the specimen and the degree of fibrosis in the sample specimen. A completer response is 0% residual cancer cells. A partial response is 10-50% residual cancer cells, and no response is >50% residual cancer cells within the tumor specimen. | cohort A - 8 weeks |
| 3-month Disease Control Rate (DCR) Will be Evaluated Using RECIST v 1.1 in Cohort B Patients. | Percentage of patients with complete response, partial response, or stable disease as a result of their therapy at 3 months | Cohort B - 3 months |
| Maximal Tolerated Dose of High Dose Vitamin C in Combination With Y90 Radioembolization | Maximal tolerated dose will be evaluated by assessment of dose limiting toxicities for multiple dose levels. Dose limiting toxicity will be defined as any grade 3-4 adverse event possibly, probably, or definitely attributed to vitamin C therapy in the 21 days of protocol therapy. In any group of 3 patients, if one patient experiences dose limiting toxicity, the group will be expanded by 3 additional patients (eg. 6 for that group). If, at any dose level, 2 or more patients experience a dose limiting toxicity, the maximal tolerated dose will be reached, and further dose escalation will not be pursued. The dose level may then be expanded up to 10 additional patients to confirm the safety and toxicity at that dose level. | Cohort C - 16 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Progression-free Survival (PFS) | PFS is defined as the time from registration to cancer progression or death due to any cause for up to 6 months. Cancer progression is defined using the Response Evaluation Criteria in Solid Tumors v1.1, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in non-target lesions, or the appearance of new lesions. | cohort B - up to 6 months |
| Measure | Description | Time Frame |

| In Vitro Activity of Vitamin C in Tumor Organoids | Molecular signature of vitamin C efficacy will be determined using RNA sequencing and compared between KRAS or BRAF mutant vs wild type tumors.

Adverse events were assessed from the start of study treatment to 30 days after the last infusion of vitamin C. For Cohort A and C, this was approximately 2 months. For Cohort B this was about a 6 month duration. Some study participants were enrolled in the trial, but did not receive study treatment, so they are not included in the at risk population.
All enrolled participants were assessed for death. Only participants treated were assessed for adverse events. Two participants that were enrolled in Cohort B Vitamin C Only were withdrawn prior to receiving study treatment. One participant that was enrolled in Vitamin C + Y-90: Dose Level 8 was withdrawn from the study before receiving study treatment. Therefore they were not included in the at risk population for adverse events, only mortality.
