Halt Aging in Survivors of Blood Cancers (HALTAging-1)

June 29, 2026 updated by: University of Nebraska

Halt Aging in Survivors of Blood Cancers: the HALTAging-1 Study

Older survivors of blood cancer are at a high risk of accelerated biological aging, which increases their risk of developing multiple aging-related conditions. Whereas physical exercise can improve overall health, older cancer survivors do not meet the recommended physical activity, highlighting the need to develop behavioral interventions to increase adherence. Several other knowledge gaps exist to implement exercise interventions in older survivors of blood cancer; the dose and duration of exercise necessary to slow biological aging in older blood cancer survivors remain unknown. To bridge these gaps in knowledge, we have designed a Phase 2 randomized control trial to test the effects of behavioral and exercise interventions on various outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Age ≥50 years
  2. A history of hematological malignancy
  3. Participants must be able to and willingly give informed consent

Exclusion Criteria:

  1. Patients receiving intensive induction or consolidation chemotherapy. Maintenance chemotherapy, or lower-intensity chemotherapy for an indolent hematological malignancy is allowed.
  2. Neurodegenerative disease (e.g. Alzheimer's dementia), stroke, or uncontrolled psychotic disorders (e.g. schizophrenia or bipolar disorder) in the past 3 months if those disorders are considered significant enough to impair participation in the study.
  3. Illnesses such as clinical evidence of decompensated heart failure, unstable angina, or orthopedic or neuromuscular disorders that could limit safe participation in aerobic exercise.
  4. Cardiopulmonary exercise test results that preclude safe exercise (e.g., life-threatening arrhythmia, balance difficulties, peak VO2 <10 ml/kg/min).
  5. Estimated life expectancy of less than 6 months (that precludes assessment of study primary endpoint).
  6. Self-reported pregnancy or the possibility of pregnancy.
  7. Participants who do not plan to follow up at the participating center.

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
Measure Description
Time Frame
Percentage of participants who adhered to the exercise regimen at 6-months post enrollment.
Time Frame: 6 Months from start of program
Participants achieving at least 120 minutes per week of moderate-intensity aerobic exercise, measured using Polar heart rate monitor data and exercise diaries.
6 Months from start of program
Percentage of participants who adhered to the exercise regimen at 12-months post enrollment.
Time Frame: 12 Months from start of program.
Participants achieving at least 120 minutes per week of moderate-intensity aerobic exercise, measured using Polar heart rate monitor data and exercise diaries to assess sustainability of adherence.
12 Months from start of program.

Secondary Outcome Measures
