Study Description

Brief Summary

This phase II trial studies the effect of atorvastatin in treating patients with ulcerative colitis who have a dominant-negative missense P53 mutation and are at risk of developing large intestinal cancer. Patients with ulcerative colitis are known to have an increased risk of developing large intestinal cancer. Better ways to control ulcerative colitis and more knowledge about how to prevent colon cancer are needed. Atorvastatin is a drug used to lower the amount of cholesterol in the blood and to prevent stroke, heart attack, and angina (chest pain). It blocks an enzyme that helps make cholesterol in the body. It also causes an increase in the breakdown of cholesterol. The information gained from this study may help doctors learn more about atorvastatin as an agent in cancer prevention, and may help to improve public health.

Colorectal Carcinoma Ulcerative Colitis	Drug: Atorvastatin Calcium Procedure: Biospecimen Collection Drug: Placebo Administration	Phase 2

Detailed Description

PRIMARY OBJECTIVE:

To determine the effect of atorvastatin calcium (atorvastatin) treatment on reducing the fraction of colonic epithelial cells expressing mutant p53 protein detected via immunohistochemical staining in biopsy samples of colorectal mucosa obtained during colonoscopies done before and after atorvastatin intervention and compared to placebo control.

SECONDARY OBJECTIVES:

Examination of the effect of atorvastatin on the levels of biomarkers including Ki-67 (cell proliferation), Waf1p21 (wild type p53 allele reactivated signal), and cleaved caspase-3 (wild type p53-induced cell apoptosis) using immunohistochemistry (IHC) approach for colorectal biopsy specimens.
Examination of the effect of atorvastatin on the spectrum, hotspot and load of TP53 gene mutations using next generation sequencing and droplet digital polymerase chain reaction (PCR).
Examination of the effect of atorvastatin on the severity of histologic inflammation in colorectal biopsies using the Geboes grading system.
Examination of the effect of atorvastatin on the plasma concentration of cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) for monitoring atorvastatin effect on lowering cholesterol and its correlation with the levels of biomarkers in the colorectal biopsies.
Examination of the effect of atorvastatin on the clinical efficacy on ulcerative colitis (UC) related symptoms using the Ulcerative Colitis Disease Activity Index (i.e. the Mayo score).
Will bank colorectal biopsies and blood samples and ribonucleic acid (RNA) and germline deoxyribonucleic acid (DNA) for future analyses, particularly on proteomics/prenylated protein profile, cytokine/chemokine profile, inflammatory lipid-mediator profile, RNA sequencing (RNAseq) and Chaperon/Co-chaperon proteins, etc.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive atorvastatin orally (PO) once daily (QD) for 12 months.

ARM II: Patients receive placebo PO QD for 12 months.

In both arms, patients also undergo collection of blood samples at each study visit to analyze the inflammation from the blood.

After completion of study treatment, patients are followed up at 2 weeks.

Outcome Measures

Primary Outcome Measures

Reduction in mutant p53 staining in biopsy samples obtained during colonoscopies done before and after intervention [Up to 2 years]
Counted as p53 positive cells/100 epithelial cells under at least 5 high powered fields per slide or 100 crypts or 2000 cells/slide per biopsy, measured by immunohistochemistry (IHC) staining. The level of biomarker expression will be determined by chromogenic staining. Because multiple samples will be obtained per participant, participant-level %p53 mutation will be summarized as the average %p53 across these samples. Descriptive statistics will be used to summarize changes in each arm, as well as the difference in change between arms. Analysis will be conducted using a two-sample t-test comparing within-subject changes in average percentage (%) p53 between treatment arms. A more comprehensive analysis will be done using a linear mixed effects model, where the outcome variable will be %p53 staining in each sample evaluated at baseline and post-treatment.

Secondary Outcome Measures

Levels of biomarkers of Ki-67 (cell proliferation), Waf1p21 (wild type p53 allele reactivated signal), and cleaved caspase-3 (wild type p53-induced cell apoptosis) [Up to 2 years]
Using IHC approach for colorectal biopsy specimens.
Analysis of spectrum, hotspot and load of TP53 gene mutations [Up to 2 years]
Using next generation sequencing and droplet digital polymerase chain reaction (PCR) technologies. The spectrum of TP53 mutations will be analyzed for frequency of each hotspot mutation in each group. For analyzing binary variables (presence or absence of each hot spot mutation), a Pearson's chi-squared test will be used. Frequency of each hotspot mutation for each noted group will be provided as descriptive measures of location and variance. The load of TP53 mutations in the biopsy specimens will be quantified as the ratio of mutant allele to wild-type allele using droplet digital PCR and allele-specific primers. Descriptive statistics will be used to summarize these at each time point for each treatment arm. Changes in TP53 mutation load, a continuous biomarker, will be compared between treatment arms using similar approaches as the primary analysis of %TP53 described above.
Histological analysis for grading the severity of histologic inflammation in colorectal biopsies [Up to 2 years]
Using the Geboes grading system (grading score: 0 - 4). Highest grade histology and extent of UC (pancolitis vs localized UC) across multiple samples will be used at each time point. Changes in scores from baseline to post-treatment will be calculated, and compared between arms using the Wilcoxon rank sum test.
Plasma concentration of cholesterol, high density lipoprotein (HDL) and low density lipoprotein (LDL) [Up to 2 years]
Will monitor atorvastatin effect on lowering cholesterol and its correlation with the levels of biomarkers in the colorectal biopsies. Changes in plasma concentration of cholesterol, HDL and LDL (for monitoring atorvastatin effect on lowering cholesterol) will be compared between treatment arms using similar approaches as the primary analysis of %TP53 described above. The association of plasma concentration of cholesterol, HDL and LDL with the levels of biomarkers in the colorectal biopsies will be analyzed using linear mixed models as described above with plasma level added to the model as a fixed effect. Separate models will be fitted for each type of cholesterol (total, HDL and LDL).
Clinical efficacy on UC related symptoms [Up to 2 years]
Using the Ulcerative Colitis Disease Activity Index (activity score: 0 - 4) (i.e. the Mayo score).
Banking of colorectal specimens [Up to 2 years]
To bank the colorectal biopsies, blood, ribonucleic acid, and germline deoxyribonucleic acid for future pooled analyses of inflammatory biomarkers, prenylated proteins and gene expression profile, statistical analysis will be used as needed.

Atorvastatin is contraindicated in pregnancy since it affects cholesterol synthesis pathway. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) from the time of baseline pregnancy test, throughout the duration of the study, and for 1 month following cessation of study drug. Females must begin adequate contraception immediately following screening pregnancy test. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately. If she is pregnant, she will be immediately withdrawn from the study and followed until the birth of the child
Ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:

Ulcerative proctitis (since patients with ulcerative proctitis have a significantly lower risk of developing colorectal cancer [CRC] than those with pancolitis or localized UC in left colon)
Subjects with medical conditions that, in the opinion of the investigator, would preclude the treatment intervention and colonoscopy, or limit ability to comply with therapy
Subjects with pancolitis or localized UC with Mayo grading >= 2 are excluded
Use of corticosteroid therapy in the past 3 months due to high potential of relapse of active disease
Use of statins in the last 12 months
