About this study
Official title: Pilot Study Assessing the Correlation Between Telomere Length and Chemotherapy- Related Toxicity Among Early Stage and Metastatic Colorectal Patients Over the Age of 70
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:
- 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:
- 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:
- 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.
- Conditions
- Mucinous Adenocarcinoma of the Colon, Mucinous Adenocarcinoma of the Rectum, Signet Ring Adenocarcinoma of the Colon, Signet Ring Adenocarcinoma of the Rectum, Stage IIIA Colon Cancer, Stage IIIA Rectal Cancer
- Being tested

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: Up to 6 months
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.
Measured: 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.
Measured: Baseline to 6 months

Are results available for this study?
The study was stopped early (reason given: Low Accrual Rate). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
TL (time frame: Up to 6 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Feb 2018; AzTrials last refreshed its copy on 7 Nov 2026.
