About this study

Official title: Cardiovascular Reserve Evaluation in Survivors of Transplantation (CREST)

This study evaluates how well the heart, lungs, and muscles are working individually, and how these systems are working together in transplant survivors. Information collected in this study may help doctors to understand why hematopoietic stem cell transplant survivors are at higher risk for developing cardiovascular disease.

Read the detailed description

PRIMARY OBJECTIVES:

  1. Evaluate cardiovascular reserve capacity, as measured by peak oxygen consumption (VO2peak), in hematopoietic cell transplantation (HCT) survivors.

II. Define the determinants of VO2peak impairment in HCT survivors.

OUTLINE:

Patients undergo echocardiogram to assess cardiac function and mechanics, cardiopulmonary exercise test, pulmonary function test, musculoskeletal ultrasound, bioelectrical impedance analysis to measure total lean body mass and percent body fat), physical function tests, and collection of blood samples within 45 days from the start of conditioning therapy, and at 6 months, 1 year, and 2 years post-transplant.

Being tested
Bioelectric Impedance Analysis, Biospecimen Collection, Cardiopulmonary Exercise Testing, Echocardiography, Physical Performance Testing
Medical subject headings
Precursor Cell Lymphoblastic Leukemia-Lymphoma, Leukemia, Myeloid, Acute, Hematologic Neoplasms, Hodgkin Disease, Myelodysplastic Syndromes, Lymphoma, Non-Hodgkin, Multiple Myeloma

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Cardiovascular reserve capacity, as measured by VO2peak, in HCT survivors

    We will measure initial VO2peak in patients prior to HCT and its post-HCT trajectory over time; compare VO2peak in HCT survivors at baseline (pre-HCT), 6m, 1Y, and 2Y post-HCT to established age- and sex-normative data; and define the association between VO2peak and self-reported health-related quality of life (HRQOL) at baseline/over time.

    Measured: Up to 24 months post-hematopoietic cell transplantation (HCT)

  2. Determinants of VO2peak impairment in HCT survivors

    We will use Generalized Estimating Equation(GEE) and generalized linear models to examine the correlation between VO2peak and measures of:

    1. cardiac (left ventricular function/ contractility [systolic, diastolic, cardiac output, strain], ventricular-arterial (VA) coupling, arterial elastance);
    2. pulmonary (obstructive, restrictive lung disease, diffusion capacity);
    3. musculoskeletal (body composition [% lean muscle mass], muscle quality, two minute step in place test, 30 second sit to stand test, timed up and go); and
    4. hematologic function, adjusting for potential confounding variables (e.g. age, sex) and time since HCT.

    Measured: Up to 24 months post-hematopoietic cell transplantation (HCT)

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Lymphoblastic Leukemia and Acute Myeloid Leukemia, run by City of Hope Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 14 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Cardiovascular reserve capacity, as measured by VO2peak, in HCT survivors (time frame: Up to 24 months post-hematopoietic cell transplantation (HCT)). 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 14 Aug 2026.
