Study Description

Brief Summary:

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.

Colorectal Cancer; Pancreatic Cancer; Lung Cancer	Drug: Vitamin C	Phase 2

Detailed Description:

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

Outcome Measures

Primary Outcome Measures :

1. Change in antitumor activity measured by pathologic response based on tumor regression grading in cohort A patients. [ Time Frame: cohort A - 8 weeks ]
   measured by tissue analysis of tumor cell death and fibrotic response in Cohort A subjects
2. 3-month disease control rate (DCR) will be evaluated using RECIST v 1.1 in cohort B patients. [ Time Frame: Cohort B - 3 months ]
   Examination of subjects with stable disease, a partial response, or complete response.
3. Maximal tolerated dose of high dose vitamin C in combination with Y90 radioembolization [ Time Frame: Cohort C - 16 weeks ]
   Maximal tolerated dose will be evaluated by assessment of dose limiting toxicities for multiple dose levels

Secondary Outcome Measures :

1. Progression-free survival (PFS) [ Time Frame: cohort B - up to 6 months cohort C - 16 weeks ]
   Defined as the time from registration to cancer progression or death due to any cause
2. Objective response rate (ORR) [ Time Frame: cohort B - up to 6 months cohort C - 16 weeks ]
   Examination of patients with a partial response or complete response based on RECIST 1.1 Criteria.
3. Assessment of pharmacokinetics of high dose vitamin C plasma levels concentrations [ Time Frame: cohort A - 8 weeks, cohort B - up to 6 months, Cohort C - 16 weeks ]
4. Safety of high dose vitamin C administration using CTCAE 4.03. [ Time Frame: cohort A - 8 weeks, cohort B - up to 6 months, Cohort C - 16 weeks ]

Other Outcome Measures:

1. In vitro activity of vitamin C in tumor organoids [ Time Frame: cohort A - 8 weeks, cohort B - up to 6 months ]
   Molecular signature of vitamin C efficacy will be determined using RNA sequencing and compared between KRAS or BRAF mutant vs wild type tumors. Organoids will be prepared from resected tumor samples and treated with vitamin C.
2. Exploratory biomarker samples from tumor tissue will be collected at the time points specified in the protocol. [ Time Frame: cohort A - 8 weeks, cohort B - up to 6 months, Cohort C - 16 weeks ]
   To explore potential correlation of gene expression pattern with anti-tumor activity of vitamin C, we plan to perform RNA sequencing using surgical sample in cohort A patients who will receive vitamin C infusion pre-operatively.
3. Pharmacodynamic samples from tumor tissue will be collected at the time points specified in the protocol. [ Time Frame: cohort A - 8 weeks, cohort B - up to 6 months, Cohort C - 16 weeks ]
   Immunohistochemical (IHC) staining for GLUT1 protein expression will be performed on Formalin Fixed Paraffin Embedded (FFPE) tumor tissues. Immunohistochemical (IHC) staining for phosphor-AMPK will be performed on Formalin Fixed Paraffin Embedded (FFPE) tumor tissues to assess AMPK activation.
