Study summary

The first aim of this study is to determine the feasibility of delivering CO-OP remotely to breast cancer survivors, who self-report cancer-related cognitive impairment (CRCI), in preparation for a future R01 trial. The second aim of this study is to assess the effect of CO-OP on activity performance, subjective and objective cognition, and quality of life in a sample of breast cancer survivors who self-report CRCI. The research team hypothesizes that effect size estimations will indicate that CO-OP will have a greater positive effect, compared to attention control, on activity performance, subjective and objective cognition, and quality of life in a sample of breast cancer survivors who self-report CRCI.

Read the detailed description

Breast cancer survivors often self-report cognitive changes after treatment for cancer (e.g. cancer-related cognitive impairment (CRCI)). These cognitive changes have a devastating impact on everyday life activities, such as work/productivity, community involvement, driving, and financial management. While CRCI would likely be amenable to rehabilitation services, breast cancer survivors face two primary barriers to adequate rehabilitation, including (1) inadequate access to rehabilitation services, and (2) limited effective interventions to address CRCI.

Breast cancer survivors have inadequate access to rehabilitation services to address CRCI. A recent report sponsored by the National Cancer Institute (NCI) concluded that most NCI-designated cancer centers do not have integrated cancer rehabilitation services. Even if comprehensive rehabilitation services were provided by these centers, millions of cancer survivors live in rural areas outside close proximity to a cancer center and are more likely to experience poorer outcomes compared to urban counterparts. If rehabilitation services were provided, proximity to facilities may be a limiting factor in individuals from rural communities receiving rehabilitative care. Access to services has been further curtailed amid the COVID-19 pandemic, with calls building from national organizations for improvements in remote delivery of services.

Metacognitive strategy training (MCST) is a practice standard to address cognitive impairment in other conditions, such as traumatic brain injury and stroke. The Cognitive-Orientation to daily Occupational Performance (CO-OP) approach is a MCST intervention in which subjects are taught a general cognitive strategy that can be applied in known and novel contexts to devise task specific strategies to engage in an activity. The investigators' preliminary data suggest that CO-OP may have a positive impact on activity performance, subjective and objective cognition, and quality of life in breast cancer survivors with CRCI. While current evidence supports the remote delivery of strategy-based interventions like CO-OP, this intervention has not been evaluated in breast cancer survivors with CRCI.

The investigators' overall research hypothesis is that CO-OP can feasibly be administered remotely and will improve activity performance, subjective and objective cognition, and subjective quality of life in breast cancer survivors with CRCI.

Study arms

  • Experimental
    Treatment Group: Cognitive Orientation to daily Occupational Performance (CO-OP)

    Each CO-OP session will last 60 minutes and subjects will complete one session per week over the course of 10 weeks. All sessions will be delivered remotely via the Zoom platform.

    Behavioral: CO-OP Procedures

  • Active comparator
    Attention Control Group

    Each session will last 60 minutes and subjects will complete one session per week over the course of 10 weeks. All sessions will be delivered remotely via the Zoom platform.

Interventions

  • BehavioralCO-OP Procedures

    CO-OP is a metacognitive strategy training intervention that will be used in this study. First, five functional, everyday life goals are identified collaboratively by the participant and interventionist. In the second meeting, we introduce the approach to the subject and teach the global cognitive strategy (i.e., GOAL-PLAN-DO-CHECK). In all subsequent sessions, this strategy is used as the main problem-solving framework to facilitate skill acquisition.The subject identifies a GOAL, and then is guided by the therapist to discover a PLAN to potentially achieve the goal. The subject is then asked to DO the plan (if feasible during the therapy session otherwise asked to complete at home prior to the next treatment session), and subsequently to CHECK to see if the plan worked, i.e. the goal was achieved. This process is repeated until satisfactory performance is met for each established goal.

  • BehavioralAttention Control Procedures

    Individuals in the attention control group will have dose-equivalent, weekly virtual contact through the Zoom platform for 12-weeks with a a trained interventionist not involved in CO-OP treatment. The control group will control for interpersonal interaction, maturation effects, and testing effects. The focus of each session will include: (1) social interaction characterized by warmth/empathy and (2) provision of usual care CRCI educational resources (e.g. exercise, using memory aids, minimizing distractions) from MD Anderson Cancer Center. These recommendations will be provided without further instruction. Any questions that arise regarding CRCI the subject is experiencing will be answered. The therapist will debrief with the subject on any changes in CRCI symptoms. The content and duration of each call will be tracked. Each session will be recorded with two randomly selected and reviewed for fidelity.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Oct 2022 to primary completion in Apr 2024, 17 months.

Results were first posted in Dec 2024, 8 months after primary completion.

Of 1,358 non-industry interventional studies with no phase under Neoplasms, half reached primary completion within 37 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 71. This study's 17 months is below that.

Counting every sponsor, half of 1,404 studies reached it within 38 months; a quarter within 17 and three quarters within 71.

Neoplasms covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

How these figures are worked out, and which studies are left out of them.

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.
No changes since tracking began. The registry record was last updated on Dec 16, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
