Study summary

The HiToP ® 191 PNP an certified device licensed for the treatment of neuropathia.

The home-based treatment is to be performed only in accordance with the approved Investigational Plan (CIP) on subjects who have signed an informed consent form. Device use is limited to the approved study investigators.

The study is multicenter, randomized, double-blind, and placebo-controlled.

Primary Objective: Comparison of the change of paresthesias from baseline until end of therapy between the two patient groups, assessed by questionnaires

Secondary Objectives: Further symptoms of neuropathy as well as on health-related quality of life.

Inclusion criteria

    • Patients with verified breast cancer and or adjuvant treatment with a taxane derivate (e.g., Paclitaxel, Docetaxel): This group was chosen due to relatively high risk of neuropathy due to this special therapeutic agent 1,9.
  • Cumulative dose of at least 3 cycles
  • Interval of 2 weeks since the last chemotherapeutic cycle in order to prevent false worsenings due to delayed neurotoxic effects
  • of at least 3 months
  • (ECOG) Performance Status score of 0-2 (that is, the capability to walk and to spend less than 50% of waking hours sitting or lying)
  • Ability to walk (with or without aids)
  • European Organisation for Research and Treatment of Cancer (EORTC) common toxicity criteria (CTC) peripheral sensory neuropathy grade 1 or 2
  • Intensity of paresthesias of > 3/10 on the Visual Analog Scale (VAS)

Exclusion criteria

Exclusion Criteria:

    • Prevalent neuropathy of different etiology
  • Serious central-neurological or psychiatric disorder that would interfer with a proper order of the study, according to the judgement of the investigators
  • Epilepsy
  • Minors or persons unable to give
  • Current neurotoxic medication
  • Implanted pacemakers or defibrillators
  • Pregnancy
  • Wounds in the area to be treated, acute local or systemic infection
  • Peripheral arterial occlusive disease > grade 2
Terms in these criteria, in plain language(5)

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Adjuvant and neoadjuvant

Neoadjuvant treatment is given before the main treatment (usually surgery), often to shrink a tumour. Adjuvant treatment is given after it, to lower the chance of the cancer coming back.

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.

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.

What researchers measure

Primary outcomes

  1. Alleviation of paresthesias (VAS)

    Visual analog scale, 0-10, higher score = worse

    Time frame: baseline vs. one day after the last treatment session

Secondary outcomes

  1. Further neuropathic symptoms (via VAS questionnaire)

    e.g., intensity of tightness, cramps, 0-10, higher score = worse

    Time frame: baseline vs. one day after the last treatment session vs. follow-up 2 weeks after the last treatment session

  2. Further neuropathic symptoms (via EORCT CIPN20 questionnaire)

    sensory, motor and autonomic scale, 1-4, higher score = worse

    Time frame: baseline vs. one day after the last treatment session vs. follow-up 2 weeks after the last treatment session

  3. Quality of life (via EORCT C30 questionnaire)

    global health status, physical function, symptom scales, 1-4, higher score = worse

    Time frame: baseline vs. one day after the last treatment session vs. follow-up 2 weeks after the last treatment session

What these dates mean
Start.
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 Apr 26, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
