Study summary

This pilot research trial studies telomere length in predicting toxicity in older patients with stage III-IV colorectal cancer undergoing chemotherapy. Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and predict how well patients will respond to treatment.

Read the detailed description

PRIMARY OBJECTIVES:

I. To determine the relationship between pre-treatment telomere length (TL) and rate of grade 3 or higher adverse events occurring on front line leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX)-based chemotherapy among patients over the age of 70 with early stage or metastatic colorectal cancer (CRC).

SECONDARY OBJECTIVES:

I. To evaluate the impact of the FOLFOX-based chemotherapy treatment on peripheral blood lymphocyte telomere length.

II. To evaluate the association between pre-treatment geriatric assessment tools scores, telomere length, and the incidence of chemotherapy related adverse events among older early stage or metastatic CRC patients.

TERTIARY OBJECTIVES:

I. To evaluate the association between pre-treatment levels of serum interleukin-6 (IL-6), C-reactive protein (CRP) and D-dimer and incidence of chemotherapy related adverse events.

II. To evaluate the correlation between pre-treatment telomere length, levels of other biomarkers of aging (IL6, CRP, D-dimer), and rates of adverse events with FOLFOX-based chemotherapy.

OUTLINE:

Patients undergo blood sample collection for analysis via real-time polymerase chain reaction (PCR) at baseline, 3 months, and 6 months.

After completion of study, patients are followed up every 3 months for up to 2 years.

Inclusion criteria

  • Both men and women of all races and ethnic groups are eligible for this trial
  • Patients must have histologically or cytologically confirmed adenocarcinoma of the colon or rectum that is stage III or IV and has not been treated with systemic chemotherapy (biopsy of metastatic site not required if primary tumor biopsied and clinical scenario is consistent with metastatic disease)
  • Patients must be deemed eligible for systemic chemotherapy with FOLFOX6 +/- bevacizumab at full standard doses
  • For patient with metastatic disease, previous adjuvant chemotherapy is allowed as long it was completed at least 12 months prior to study enrollment and did not include oxaliplatin
  • Prior radiation therapy is allowed but must have been completed >= 4 weeks prior to study entry
  • Eastern Cooperative Oncology Group (ECOG) performance status \< 2
  • Leukocytes >= 3,000/mcL
  • Absolute neutrophil count >= 1,500/mcL
  • Platelets >= 100,000/mcL
  • Total bilirubin within normal institutional limits
  • Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =\< 2.5 X institutional upper limit of normal
  • Creatinine within normal institutional limits, or creatinine clearance >= 50 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal
  • Patients must demonstrate ability to understand and the willingness to sign a written informed consent document
  • Patients must demonstrate ability to complete study questionnaires
  • Patients must provide written informed consent and Health Insurance Portability and Accountability Act (HIPAA) consent prior to performance of study-specific procedures or assessments and must be willing to comply with treatment and follow up
  • Male participants with female partners who are of childbearing potential must agree to use an acceptable and effective method of contraception

Exclusion criteria

Exclusion Criteria:

  • Patients with metastatic disease who have had adjuvant chemotherapy with oxaliplatin within 12 months of enrollment (single agent fluorouracil [5FU] or capecitabine is allowed) or radiotherapy within 4 weeks prior to entering the study
  • Patients with known brain metastases should be excluded from this clinical trial
  • Patients with a known history of allergic reactions attributed to compounds of similar chemical or biologic composition to the agents used in the study
  • Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection-requiring intravenous (IV) antibiotics, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
  • Known human immunodeficiency virus (HIV)-positive patients and those with known hepatitis B or C are excluded from the study
  • Patients with evidence of other cancer within 5 years, excluding adequately treated basal cell carcinoma of the skin

What researchers measure

Primary outcomes

  1. TL

    TL will be compared between participants experiencing at least 1 adverse event and those who experience none using the Mann-Whitney test. A type I error of 5% will be used to determine statistical significance.

    Time frame: Up to 6 months

  2. Incidence of chemotherapy related grade 3 or higher adverse events, graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0

    Variance stabilizing and normalizing transformations will be applied to the data when appropriate. Descriptive statistics for participant characteristics, disease presentation, treatment related toxicity, treatment, duration of chemotherapy use, management of adverse events, and frequency of treatment discontinuation will be tabulated. TL will be compared between participants experiencing at least one adverse event and those who do not experience any adverse event using the Mann-Whitney test. A type I error of 5% will be used to determine statistical significance.

    Time frame: Up to 6 months

Secondary outcomes

  1. Change in TL after chemotherapy

    Variance stabilizing and normalizing transformations will be applied to the data as and when appropriate. TL measured at 3 months and at 6 months after chemotherapy treatment will be compared to baseline (pre-treatment) using the Wilcoxon test or the paired t-test as appropriate. A type I error of 5% will be utilized to determine statistical significance. Pre- and post-treatment TL will be summarized using descriptive statistics.

    Time frame: Baseline to 6 months

Other outcomes

  1. Association of each geriatric scale, and pro-inflammatory markers to the incidence of chemotherapy related adverse events and TL

    Continuous variables will be assessed using the Kruskal-Wallis test or analysis of variance as appropriate and categorical variables will be assessed using Fisher's exact test. Wherever appropriate, Pearson correlation or Spearman's rank correlation will be used to quantify the degree of association between the scales/biomarkers and TL.

    Time frame: Up to 6 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 7, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
