Study summary

Cancer and treatment-related cognitive changes, such as thinking or remembering, hinder resumption of normal routine and roles and worsen quality of life. Older adults undergoing hematopoietic cell transplantation (HCT) are at high-risk for cognitive impairment. Age is a risk factor for Alzheimer's Dementia (AD) and the hematological malignancies leading to HCT. There are shared mechanisms and interactions between AD and cancer-related cognitive decline (CRCD). Physical activity improves cognitive function in older adults and survivors of other cancers. This study hypothesizes that increasing physical activity can also improve cognitive function in this vulnerable population.

The study has two goals. The first is to adapt and test an evidence-based physical activity intervention, The Community Health Activities Model Program for Seniors II (CHAMPS II), in the HCT setting for adults 55 years and older. This will be done using semi-structured interview of up to 10 patients who have experienced the HCT process within the last 3 to 6 months with HCT care-team partners.

The second goal will explore the prevalence and impact of AD-neuropathology and inflammation on cancer-related cognitive decline (CRCD) in older adults undergoing HCT.

Read the detailed description

Hematologic malignancies are diseases that primarily affect older adults, with a median age at diagnosis of 65 years. Hematopoietic cell transplantation (HCT) is a potentially curative and life-prolonging treatment for patients with hematologic malignancies. Cancer and treatment-related cognitive changes cause distress, hinder resumption of normal routine and roles, and worsen quality of life. HCT differs from the delivery of chemotherapy in other cancer settings due to the intensity of chemotherapy and severity of toxicity. Older adults undergoing HCT are at high risk for cognitive decline and pervasive cognitive deficits. Interventions to improve cognitive outcomes are needed. The prevalence and risk of cognitive decline post-HCT are greater for older adults because of a greater number of existing health conditions (i.e., vascular disease) and impaired physical and psychologic function pre-HCT that can be exacerbated by treatment and the overall HCT experience.

Exercise training improves cancer-related health outcomes, including cardiorespiratory fitness, inflammation, cancer related fatigue, depressive symptoms, and sleep disturbance. There is consistent evidence showing that physical activity improves cognitive function in older adults and survivors of other cancers. Improvement in cardiorespiratory fitness, brain structure, and inflammation underlie the mechanisms of the cognitive benefits of physical activity. While untested in older adults undergoing HCT, the investigator hypothesizes that increasing physical activity can also improve cognitive function in this vulnerable population.

Physical activity improves the cognitive domains most affected by cancer treatment, namely executive function and working memory. Cognitive function is an important outcome to older adults and has not been a focus of physical activity interventions in the HCT population. In addition, older adults are underrepresented in previous physical activity interventions in the HCT population.

Investigators will adapt CHAMPS II, an evidence-based physical activity intervention, to the HCT setting for older adults to improve cognitive function. This is an individually tailored program that provides information, skills, training, and problem-solving support to older adults. The program provides a foundation for application by including an instructor manual and directions for implementation. CHAMPS-II has been adapted and implemented in diverse communities using existing resources and improving contextual factors to increase physical activity for sedentary older adults.

Adaptation of evidence-based interventions, such as CHAMPS-II, can result in an attenuation of effects if the core components are not maintained. However, adaptations can be made to fit the needs and priorities of the service setting, target audience, mode of delivery, and cultural context without compromising CHAMPS-II effectiveness. Through a research-practice partnership approach, investigators will help adapt the program while maintaining the core components of CHAMPS-II, develop new program materials, provide training, monitor implementation, and conduct program evaluation. The overarching goal is to enable HCT team members to implement CHAMPS-II and leverage existing organizational resources to enhance feasibility and sustainability.

The research plan proposes a hybrid effectiveness-implementation design, which is a design that spans the effectiveness and implementation research to accelerate the translation of physical activity interventions into practice for older adults with cancer. This novel trial design will allow testing of the program within a randomized clinical trial methodology while observing and gathering information on implementation. The effectiveness study condition offers an ideal opportunity to examine implementation issues and plan for implementation strategies for a future study that examines both effectiveness and implementation strategies. The study will use the RE-AIM (Reach, Effectiveness - Adoption, Implementation, and Maintenance) framework for planning and formative and process evaluation of the intervention. Formative and process evaluation provides information needed to evaluate an intervention's potential for translation into clinical practice.

Investigators aim to understand the prevalence and impact of AD-neuropathology and inflammation on cognitive function and structural brain changes in older adults undergoing HCT. Quantifiable AD-related neuropathology can accumulate silently for decades with no clinical symptoms. Some will have no AD pathology, some will have "silent" AD pathology, and some will have clinically relevant levels of AD pathology. Brain volumes is also a measure of cognitive reserve with many factors that could impact brain volumes including aging, AD, other degenerative diseases, untreated obstructive sleep apnea (OSA), chronic stress, and ethyl alcohol or ethanol abuse (ETOH). Some patients with low brain volumes may have negative AD biomarkers. However, brain volumes may be a good predictor of CRCD. Investigators expect to gain an understanding of the prevalence of between-subject variability in the quantity of AD neuropathology and differences in brain volume. The results of this research will lay the groundwork for future funding opportunities to elucidate the bidirectional mechanisms, prevention and treatment of AD and CRCD in this population.

Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Interventions

  • BehavioralCHAMPS-II adapted to adults 60+ years in HCT setting

    CHAMPS-II is an evidence-based physical activity program designed to increase physical activity in sedentary older adults with multiple chronic health conditions. This is an individually tailored program that provides information, skills, training, and problem-solving support to older adults. Participants will engage in progressive, light to moderate-intensity physical activity throughout the HCT process, with the support of physical therapists, physical activity counselors, and their care-partner. They will take part in supervised exercise sessions; unsupervised exercise sessions; counseling sessions to address barriers, motivators, goals, and safety; and receive telephone support. Walking is the primary mode of aerobic activity, with training in flexibility, strengthening and balance exercises also included. An exercise kit will be provided, consisting of an intervention workbook, therapeutic resistance bands, and activity logs.

  4. Change in working memory as measured by the Hopkins Verbal Learning Test-Revised (HVLT-R).

    Change in raw scores and z-scores, determined by the following neuropsychological test: Hopkins Verbal Learning Test-Revised (HVLT-R). There are 3 learning trials and 1 delayed recall trial. Minimum score for each is zero and maximum is 12; higher score means better outcome. There is also a delayed recognition trial where person is presented with both true positives and false positives. Minimum score for both is zero and maximum is 12. For the true positives a higher score means better outcome. For the false positives a lower score means better outcome.

    Time frame: 12 weeks

Secondary outcomes

  1. Change in global cognitive function as measured by the Montreal Cognitive Assessment (MoCA).

    Change in total score, determined by objective measures of global cognitive function using the Montreal Cognitive Assessment (MoCA). Minimum score is zero and maximum is 30; higher score means better outcome.

    Time frame: 12 weeks

  2. Change in subjective memory as measured by the Neuro-Quality of Life (QOL) Cognition Function-Short Form.

    Change in total score, determined by patient questionnaire: Neuro-Quality of Life (QOL) Cognition Function-Short Form. Minimum score is 8 and maximum score is 40; higher score means better outcome.

    Time frame: 12 weeks

Other outcomes

  1. Change in functional ability as measured by the Short Performance Physical Battery (SPPB).

    Time frame: 52 weeks

  7. Change in AD biomarkers as measured by plasma Tau and p-Tau 217.

    The characteristic neurofibrillary tangles of AD are composed of pathological tau proteins. Two different measures of tau will be obtained: total tau and phosphorylated tau 217 (p Tau-217). Total tau will be assayed with a Quanterix Simoa Tau 2.1 Kit. The design of this assay identifies all isoforms of the tau protein, hence "total tau". Phosphorylated tau-217 (p-Tau 217) will be assayed with a Quanterix ALZPath Simoa p-Tau217 V2 Assay Service.

    Time frame: 52 weeks

  8. Change in biomarkers of inflammation as measured by IL6, IL8, IL10, TNF alpha, and CRP.

    Quanterix will measure IL-6, IL-8, IL-10 and TNFa via a Kit Hu 4-Plex SP-116 for cytokines, and C-reactive protein (CRP) via a Simoa CRP Developer Kit.

    Time frame: 52 weeks

  9. Presence or absence of AD-related neuropathology as measured by APOE e4 carrier status.

    AD genotyping for APOE alleles will be collected via a saliva swab. Apolipoprotein E (APOE) is a complex glycolipoprotein that facilitates the uptake, transport, and distribution of lipids. Numerous studies have shown cognitive vulnerability in non-demented APOE-e4 carriers relative to non-APOE-e4 carriers. APOE will be processed by Salimetrix.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
