Identification of Patients With Age-Related Clonal Hematopoiesis (ARCH) Among Cancer Survivors (ARCH-001)

January 29, 2025 updated by: University Health Network, Toronto

Identification of Patients With Age-Related Clonal Hematopoiesis (ARCH) Among Cancer Survivors.

The purpose of this study is to see if patients with cancer have a certain amount of genetic mutations in their blood. If certain levels of mutations are found in specific genes, patients may have a condition known as ARCH. The prevalence of ARCH is higher in cancer patients who received prior chemotherapy or radiation. Studying ARCH from your blood samples may also help researchers predict which patients are more likely to be prone to heart disease. Patients who are about to start chemotherapy/radiation, and patients who have completed chemotherapy/radiation will be approached to measure the incidence of ARCH. 5-10mL blood samples will be collected before and after treatment, and if ARCH is detected in a laboratory analysis, another blood sample will be collected. Patients with ARCH will repeat the blood collection yearly, and also be referred to a cardiology clinic for follow up.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a non-randomized, single-centre, observational study assessing the incidence of ARCH in cancer survivors. Patients over the age of 60 who had or will receive chemotherapy and/or radiation therapy for solid or hematologic malignancies at the Princess Margaret Cancer Centre will be considered. Based on the time point of treatment, patients will either fall into a post or prior chemotherapy/radiation cohort. Peripheral blood will be taken and will be sequenced for ARCH DNA mutations. Patients who have ARCH-related mutations at a variable allele frequency (VAF) of at least 0.5% we will repeat the genetic sequencing yearly to assess changes in mutational spectrum and VAF over time.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

N/A

Sampling Method

Non-Probability Sample

Study Population

Patients over the age of 60 who had or will receive chemotherapy and/or radiation therapy for solid or hematologic malignancies at the Princess Margaret Cancer Centre

Description

  • Age ≥ 60

  • Completed chemotherapy and/or radiation therapy and are being followed at Princess Margaret Cancer Centre i) Patient must be in remission for > 3 months after completing chemotherapy or radiation ii) Predicted 5 year survival of >75% iii) Peripheral blood counts must have returned to normal as defined by:

    1. Platelets ≥ 100 x 109/L
    2. PMN ≥ 1 x 109/L

Or

  • Prior to chemotherapy and/or radiation therapy at the Princess Margaret Cancer Centre.
  • All histologically/cytologically proven tumour types (solid tumours and hematologic malignancies) will be eligible.
  • Received or will receive regimens of chemotherapy or radiation with doses expected to produce transient myelosuppression (PMN<0.5x109/L) in at least 80% of treated patients (The identification and definition of appropriate myelosuppressive chemotherapy and radiation regimens will be at the discretion of the treating physician and will vary among disease sites).
  • Patients must have the ability to understand the requirements of the study and provide written informed consent, which includes authorization for release of protected health information
  • Patient must be willing to provide a peripheral blood sample.

Exclusion Criteria:

  • Any other condition that would, in the Investigator's judgment, contraindicate the patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Referral to cardiology clinic
Time Frame: 6-12 months
6-12 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
The incidence of ARCH stratified by tumor type.
Time Frame: 6-12 months
6-12 months

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Time Frame
The spectrum of mutations stratified by tumor type.
Time Frame: 6-12 months
