- Adult, Older adult
Who may be able to join
- Patients with a clinical or pathologic confirmed diagnosis of prostate cancer
- Patients must be undergoing treatment with standard androgen deprivation therapy (i.e., GnRH agonist or antagonist) for ≥ 4 weeks. Patients must remain on ADT for the duration of the study (12 weeks); they may receive treatment with an androgen receptor pathway inhibitor (ARPI), radioligand therapy, or immunotherapy combined with ADT.
- Patients must report bothersome hot flash symptoms (defined as ≥ 28 hot flashes per week, perceived to be at least moderately bothersome to the patient), during a period of at least 30 days prior to entering the study.
- Age ≥18 years.
- ECOG performance status ≤ 2
- Ability to understand and the willingness to sign a written informed consent document.
Who cannot join
- Pregnant and nursing women are excluded as prostate cancer is a disease of men.
- Participants with a concurrent diagnosis, including separate malignancy, that may limit life expectancy < 6 months.
- Systemic antineoplastic therapy besides approved ARPI, radioligand therapy, and immunotherapy - enrollment in a clinical trial that is using SOC therapeutic options in these categories is allowed.

About this study
Official title: Reduce Hot flashEs AssociaTed With ADT (Reduce HEAT) - a Prospective Randomized Clinical Trial of a Wearable Thermal Device for Patients With Prostate Cancer on ADT With Bothersome Vasomotor Symptoms
This is a prospective, randomized, non-pharmacologic interventional trial evaluating the effectiveness of the Embr Wave wearable thermal device in reducing hot flash burden in men with prostate cancer receiving androgen deprivation therapy (ADT). Participants will be randomized 1:1 to immediate (12 weeks) versus delayed (after 6 weeks) use of the Embr Wave device. The study aims to determine whether the device reduces vasomotor symptoms using a number of patient-reported outcomes
Read the detailed description
This is a randomized, supportive care trial in which men with prostate cancer on ADT and experiencing bothersome hot flashes will be assigned to either immediate use of the Embr Wave device for 12 weeks or delayed use (usual care for 6 weeks, then device for 6 weeks). The Embr Wave is a commercially available wearable device that provides a cooling sensation and is being tested for its ability to reduce hot flash severity and improve quality of life. Participants will be enrolled across the DF/HCC consortium and collaborative sites.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Embr WaveDevice
A wearable thermal device that provides a cooling sensation on the wrist. The device is commercially available but not specifically approved for hot flashes in men with prostate cancer.
| Study group | Role | What they receive |
|---|---|---|
| Immediate Embr Wave Device Use | Experimental | Participants receive the Embr Wave device at the start of the study and use it for 12 weeks. Receives: Device: Embr Wave |
| Delayed Embr Wave Device Use | Active comparator | Participants receive usual care for the first 6 weeks, then receive the Embr Wave device for the next 6 weeks. Receives: Device: Embr Wave |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hot Flash Related Daily Interference Scale (HFRDIS) Score
HFRDIS is a 10-item patient-reported questionnaire that measures the degree to which hot flashes interfere with daily activities and quality of life. Each item is scored on a 0-10 numeric rating scale. Total scores range from 0 to 100, with higher scores indicating greater interference from hot flashes.
Measured: Assessed 6 weeks after randomization
Secondary outcomes (9)
HFRDIS Score [week 12]
HFRDIS is a 10-item patient-reported questionnaire that measures the degree to which hot flashes interfere with daily activities and quality of life. Each item is scored on a 0-10 numeric rating scale. Total scores range from 0 to 100, with higher scores indicating greater interference from hot flashes.
Measured: Assessed at 12 weeks after randomization
Patient Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Score
PROMIS sleep disturbance instrument is a 4-item patient-reported questionnaire that assesses perceived sleep quality, difficulty falling asleep, difficulty staying asleep, and satisfaction with sleep. Each item is scored on a 1- to 5-point Likert scale. Total scores range from 4 to 20, with higher scores indicating greater sleep disturbance (poorer sleep quality).
Measured: Assessed at 6 weeks and 12 weeks after randomization
PROMIS Sleep-Related Impairment Score
PROMIS sleep-related impairment instrument is a 4-item patient-reported questionnaire that assesses alertness, sleepiness, tiredness, and impairment in daytime functioning related to sleep.

Questions about this trial
What is this clinical trial studying?
A study testing Embr Wave in people with Prostate Cancer and Hot Flashes, run by Dana-Farber Cancer Institute at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 25 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Daniel Sentana Lledo, MD (617-632-3466, daniel_sentanalledo@dfci.harvard.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Hot Flash Related Daily Interference Scale (HFRDIS) Score (time frame: Assessed 6 weeks after randomization). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Sep 2026.
