Evaluating a Novel Web-based Intervention for Breast Cancer Survivors

Not Applicable

Terminated

• Conditions: Breast Cancer
• Interventions: Behavioral: Optimune; Other: Care-As-Usual

• Registration Number: NCT03448250
• Lead Sponsor: Technical University of Dortmund

Brief Summary

The trial aims to evaluate the effectiveness of a novel web-based intervention (Optimune), which was designed to introduce relevant cognitive-behavioral therapy (CBT) techniques to women with breast cancer who are past the active eradication phase and free from disease recurrence. The present study will test the hypothesis that Optimune has an impact on immune status, markers of inflammation and psychometric outcomes. Therefore, 150 woman with breast cancer will be recruited and randomized to two groups: (1) a control group, in which they may engage with any treatment (Care-as-Usual, CAU) and receive access to Optimune after a delay of 6 months (i.e., CAU/wait list control group), or (2) to a treatment group that immediately receives 12-month access to Optimune and may also use CAU. The primary outcome measure is the effect on inflammatory parameters six month post-baseline.

Detailed Description

Depression and fatigue is common in breast cancer survivors and its presence is associated with personal suffering, increased inflammatory activity, and worse prognosis. While in the phase of acute treatment many women receive short-term psychological support to better cope with the situation, this is not standard of care in the years following. Web-based psychological interventions are easily accessible and preliminary evidence suggests that such interventions can be effective. However, no trial has yet examined whether a CBT-based internet intervention designed to meet the needs of breast cancer survivors can achieve effects on immune status, inflammation and psychometric outcomes, when offered as adjunct to care as usual.

In this study, the investigators will study treatment effects of the novel web-based program Optimune when added to treatment as usual. Beyond established CBT techniques targeting depression, anxiety, and fatigue, this intervention specifically includes elements that have shown effects on markers of immune status and inflammation, including sleep and stress management (e.g., mindfulness-based techniques) and lifestyle optimization (dietary and physical activity advice). The delivery and training of content is continuously individualized to match users' preferences and needs, based on responses within the program. The intervention is delivered via the internet and protected by individually assigned passwords. The program can be accessed for 365 days after registration.

This randomized controlled trial will include 150 women with breast cancer who are past the active eradication phase and free from disease recurrence. Participants will be recruited from various settings, including web-based advertisement and internet forums/groups. Participants will be randomly assigned to either (1) a control group, in which they receive care as usual (CAU) and are given access to the web-based intervention (Optimune) after a delay of 6 months (i.e., CAU/wait list control group), or (2) a treatment group that may also use CAU and in addition immediately receives 12-month access to the web-based intervention (Optimune). Measurements are collected at pre-treatment (T0) three months (T1), six months (T2), nine months (T3) and twelve months (T4).

Arm && Interventions

Group	Intervention	Description
Optimune	Optimune	Optimune is an web-based psychological intervention for women with breast cancer. Beyond established CBT techniques targeting depression, anxiety, and fatigue, this intervention specifically includes elements that have shown effects on markers of immune status and inflammation, including sleep, stress management (e.g., mindfulness-based techniques) and lifestyle optimization (dietary and physical activity advice). Content is continuously adapted to users' concerns and needs. It contains interactive dialogues that can be accessed via computer or smart-phone, illustrations, audio files and motivating text messages. Optional daily text messages with motivational content accompany the program. The program can be accessed for 365 days after registration.
Care-as-Usual	Care-As-Usual	As in the experimental arm, participants are free to continue to engage with any treatment they require (i.e., CAU). However, they will receive access to Optimune six months post-baseline (i.e., wait list with respect to Optimune access).

Cortisol awakening response (CAR)	Change from baseline to 6 months (also assessed at 12 months post-baseline)	Cortisol concentrations from saliva samples taken at time of awakening and 30 and 45 min. after awakening will be measured to determine the Cortisol awakening response (CAR)
Determination of depression	Change from baseline to 3 months (also assessed at 6, 9 and 12 months post-baseline)	Depression will be measured using the standardized PHQ-9 (Patient Health Questionnaire). Scale Range: 0 to 27 The PHQ-9 is a multipurpose instrument for screening, diagnosing, monitoring and measuring the severity of depression. PHQ-9 scores of 5, 10, 15, and 20 represents mild, moderate, moderately severe and severe depression.; Interpretation: Higher scores correspond to greater self-reported levels of depression.
Determination of cancer-related fatigue using the Brief Fatigue Inventory Questionnaire	Change from baseline to 3 months (also assessed at 6, 9 and 12 months post-baseline)	Fatigue will be measured using the Brief Fatigue Inventory Questionnaire (BFI-9) questionnaire. Scale Range: 0 to 90.; The BFI is a 9-item, 11-point rating scale. The first three questions measure fatigue severity from 0, indicating "no fatigue," to 10, indicating "as bad as you can imagine," at current, usual, and worst levels. The following six questions assess fatigue interference with daily activities. Response options range from 0, indicating "does not interfere," to 10, indicating, "completely interferes." Interpretation: A global fatigue score can be obtained by averaging all the items on the BFI.; Higher scores on the BFI correspond to greater self-reported levels of fatigue
Determination of cancer-related emotional stress	Change from baseline to 3 months (also assessed at 6, 9 and 12 months post-baseline)	Cancer-related emotional stress will be measured using the standardized IES-R (Impact of Event Scale) Questionnaire. Scale Range: 0 to 88 The IES-R is a 22-item self-report measure that assesses subjective distress caused by traumatic events. Items are rated on a 5-point scale ranging from 0 ("not at all") to 4 ("extremely"). The IES-R yields a total score (ranging from 0 to 88) and subscale scores can also be calculated for the Intrusion, Avoidance, and Hyperarousal subscales.; Interpretation: Higher scores correspond to greater self-reported levels of post-traumatic stress.
Determination of fear of progression	Change from baseline to 3 months (also assessed at 6, 9 and 12 months post-baseline)	Fear of progression will be measured using the standardized PA-F12 (Fear of progression) questionnaire. Scale Range: 12 - 60 The PAF-12 items are scored on a five-point Likert Scale ranging from 1 ('never') to 5 ('very often'), higher values indicating higher levels of anxiety.; Interpretation: Higher scores correspond to greater self-reported levels of fear of progression.
Determination of anxiety	Change from baseline to 3 months (also assessed at 6, 9 and 12 months post-baseline)	Anxiety will be measured using the standardized GAD-7 (Generalized Anxiety Disorder) questionnaire. Scale Range: 0 to 21 The GAD-7 is an instrument for screening, diagnosing, monitoring and measuring the severity of anxiety. GAD-7 scores of 5, 10, and 15 represents mild, moderate, and severe anxiety.; Interpretation: Higher scores correspond to greater self-reported levels of anxiety.
Determination of usefulness of the program	Assessed at 3, 6, 9 and 12 months	Usefulness of the program will be measured by a questionnaire
Determination of Negative Effects	Assessed at 3, 6, 9 and 12 months	Negative Effects will be measured using the standardized INEP (Inventory for the Assessment of Negative Effects of Psychotherapy) questionnaire.
