- Cumulative incidence rate of the composite endpoint of adenomas (tubular, tubulovillous and serrated), advanced adenomas and colon cancer [ Time Frame: At 104 weeks ]Will be compared between the two arms using a stratified Cochran-Mantel-Haenszel test where the randomization stratification factors will be included as strata. The cumulative events rates will be reported for each study arm along with the corresponding two-sided 95% confidence intervals.
- Association of clinical factors with immune responses [ Time Frame: At 104 weeks ]Will be evaluated by conducting univariate and multivariate binary regression analyses. These analyses will be conducted for both arms combined (in which case arm is included as a stratification factor in the model) and each arm separately. The proportions of cells within adenomas expressing stem cells markers pre- and post-vaccination will be compared within each study arm using the signed rank test, and within-subject changes will be compared between responders and non-responders using Wilcoxon rank-sum test for each arm separately and both arms combined. Comparisons between study arms will be conducted using a Wilcoxon rank-sum test.
- Incidence of extracolonic neoplasms [ Time Frame: At 104 weeks ]Will compare the observed incidences of lynch syndrome (LS)-related extracolonic cancers to historical control incidence of LS-related extracolonic cancers in this patient population. We will collect the information about extracolonic cancers by asking the participants and by reviewing the pathology reports for confirmation.
- Number of antigen-specific T-cells, peripheral blood mononuclear cells (PBMCs), serum soluble factors and antibody levels [ Time Frame: At baseline, 12 weeks, and 56 weeks ]Will be log-transformed before conducting any analyses. Comparisons of number of antigen-specific T-cells, PBMCs, serum soluble factors and antibodies between study arms will be conducted using a nonparametric Wilcoxon rank sum test. IgG titers that will be measured serially will be analyzed and compared between the two arms using linear mixed effects models. If zero-inflation is detected, generalized linear mixed models with zero-inflated Poisson or negative binomial distributions will be fitted.
- Prevalence of immune cells markers, tumor associated antigens and stem cell markers [ Time Frame: At baseline, 52 weeks, and 104 weeks ]Will be reported using repeated measures techniques. We will also compare pre- and post-vaccination size, number and histology of polyps.
- Differential expression analyses [ Time Frame: At baseline, 52 weeks, and 104 weeks ]Will be using Bioconductor R package DESeq2. A paired sample design to compare post- to pre-vaccination samples within each study arm and for both arms combined. Significant genes with Benjamini-Hochberg-adjusted p-value =< 0.05 and absolute value of log2-fold change >= 0.5 will be annotated with pathways of interest in volcano plots.
- Immune cell gene enrichment analysis [ Time Frame: At baseline, 52 weeks, and 104 weeks ]Will be calculated using raw read counts with Bioconductor R package GSVA.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
-
Participants with LS defined as one of the following:
- Mutation positive: MLH1, MSH2/EPCAM and MSH6 genotypes with prior history of >= 1 adenoma(s) and/or >= 1 advanced adenoma(s) and/or colon cancer(s) (but no active cancer for 6 months) OR
- PMS2 genotype with prior history of colon cancer(s) (but no active cancer for 6 months)
- Participants must have at least part of the descending/sigmoid colon and/or rectum intact
- Participants must be at least 6 months from any cancer-directed treatment (such as surgical resection, chemotherapy, immunotherapy or radiation)
- Participants >= 18 years will be enrolled. Because the risk of LS related cancers is very low in participants < 18 years of age, children and adolescents are excluded from this study
- Eastern Cooperative Oncology Group (ECOG) performance status =< 1 (Karnofsky >= 70%)
- Leukocytes >= 3,000/microliter
- Absolute neutrophil count >= 1,500/microliter
- Platelets >= 100,000/microliter
- Total bilirubin within normal institutional limits
- Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 1.5 x institutional upper limit of normal
- Creatinine within normal institutional limits
- The effects of the Tri-Ad5 vaccines and N-803 on the developing human fetus at the recommended therapeutic dose are unknown. For this reason, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her study physician immediately
- Ability to understand and the willingness to sign a written informed consent document
- Participants must be willing and able to space coronavirus disease (COVID) vaccines at least 2 weeks prior to and 2 weeks after receipt of study agent
Exclusion Criteria:
- History of organ allograft or other history of immunodeficiency
- Known human immunodeficiency virus (HIV) with CD4 count < 540, hepatitis B virus (HBV), or hepatitis C virus (HCV) infection. Subjects with laboratory evidence of cleared HBV and HCV infection will be permitted. Poorly controlled HIV may prevent an adequate immune response to the vaccine and will be an exclusion criterion
- Subjects requiring systemic treatment with corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 3 months of vaccination
- Participants may not be receiving any other investigational agents
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to adenovirus-based vaccines and N-803
- Uncontrolled intercurrent illness or psychiatric illness/social situations that would limit compliance with study requirements
- Pregnant women are excluded from this study because of the unknown effects of the vaccine and N-803 on the fetus. Because there is an unknown but potential risk for adverse events (AEs) in nursing infants secondary to treatment of the mother with the vaccine plus N-803, breastfeeding should be discontinued if the mother is treated with the vaccine plus N-803
- History of untreated thrombotic disorders
- Participants who experienced severe side effects or allergic reactions to previous adenovirus-based vaccines (such as Johnson and Johnson COVID vaccine) will be excluded
