Guided Digital Self-Hypnosis Solution for Managing Hot Flashes in Patients Undergoing Adjuvant Hormone Therapy (HYBOU)

February 12, 2026 updated by: Institut de Cancérologie de Lorraine

Patients treated for breast cancer with hormone therapy (HT) suffer from hot flashes. This side effect impacts treatment adherence. Indeed, approximately 50% of women take less than 80% of the prescribed dose, and up to 50% abandon their treatment before the fifth year of prescription, significantly increasing the risk of recurrence. Moreover, these hot flashes strongly impact the quality of life. According to the CANTO study, these hot flashes can persist up to two years after diagnosis, affecting social relationships, return to work, and physical and mental health.

Some side effects resulting from HT (sleep disturbances, fatigue, hot flashes) could be alleviated by a non-pharmacological approach involving the patient.

Our hypothesis is that a non-pharmacological solution, such as the use of self-hypnosis, could reduce hot flashes and the side effects related to HT or the perception thereof in patients treated for breast cancer. Consequently, this could improve the quality of life and lead to better treatment adherence.

The principal objective is to evaluate the effect of daily guided self-hypnosis sessions in reducing hot flashes in patients with non-metastatic breast cancer receiving anti-aromatase hormone therapy.

The secondary objectives are to evaluate :

  • Patient adherence to guided self-hypnosis via a digital solution
  • Quality of life
  • Sleep quality
  • Satisfaction with care
  • Usability of the digital tool

The originality of this clinical trial is the proposal of self-hypnosis sessions over three weeks with three different themes using a digital solution.

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.

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.

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
Hot Flash Score (HFS)
Time Frame: 28 days

In each group (standard and hypnosis), hot flashes will be primarily assessed using the Hot Flash Score (HFS) [Elkins et al. 2013], calculated through daily measurements as follows: HFS = frequency × average severity of hot flashes, where severity is rated from 1 to 4 (1: mild, 2: moderate, 3: severe, 4: very severe). The weekly HFS is calculated by averaging the daily HFS scores for each patient.

Secondly, we will also evaluate the effect of guided self-hypnosis in reducing the frequency of hot flashes.
28 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Patient adherence
Time Frame: 28 days
calculated from the data automatically recorded by the digital solution software. Adherence is thus evaluated by the rate of session follow-ups, estimated by the proportion of patients who followed all the recommended sessions without interruption, for the hypnosis group only.
28 days
Score of quality of life
Time Frame: 28 days
Assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire at Day 0 and Day 28. The global score ranges from 0 to 100. For each question the scale ranges from 0 = not at all to 4 = a lot.
28 days
Sleep quality
Time Frame: 28 days
Evaluated using the Pittsburgh Sleep Quality Index questionnaire score at Day 0 and Day 28. The global score ranges from 0 to 21. Higher scores indicate poorer sleep quality, with a score greater than 5 suggesting significant sleep difficulties.
28 days
Patient satisfaction
Time Frame: 28 days
Assessed at Day 28 using a numerical scale. The numerical scale ranges from 0 = not satisfied to 10 = very satisfied.
28 days
Usability of the digital tool
Time Frame: 28 days
Assessed at Day 28 using the System Usability Scale questionnaire score (Gronier & Baudet, 2021) for the hypnosis group only. It's composed of 10 questions on a scale from 0 = strongly disagree to 5 = strongly agree
