Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • 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.
  • performance status ≤ 2
  • Ability to understand and the willingness to sign a written document.

Exclusion criteria

Exclusion Criteria:

  • Pregnant and nursing women are excluded as prostate cancer is a disease of men.
  • Participants with a concurrent diagnosis, including separate , that may limit \< 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.
Terms in these criteria, in plain language(4)

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.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

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.

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.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Study arms

  • Experimental
    Immediate Embr Wave Device Use

    Participants receive the Embr Wave device at the start of the study and use it for 12 weeks.

    Device: Embr Wave

  • Active comparator
    Delayed Embr Wave Device Use

    Participants receive usual care for the first 6 weeks, then receive the Embr Wave device for the next 6 weeks.

    Device: Embr Wave

Interventions

  • DeviceEmbr Wave

    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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: Assessed 6 weeks after randomization

Secondary outcomes

  1. 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.

    Time frame: Assessed at 12 weeks after randomization

  2. Patient Reported Outcomes Measurement Information System (PROMIS) Sleep Disturbance Score
