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

May 12, 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.

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

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.
