About this study

Official title: The Effect of Innovative TRPM8 Activators Membrane-Based Delivery System on Peripheral Neuropathy

The goal of this pilot prospective cohort study is to evaluate the efficacy of a novel hand and foot mask in alleviating symptoms of peripheral neuropathy caused by chemotherapy or diabetes. The study aims to determine whether regular use of these masks can improve patient comfort and quality of life.

The primary questions this study aims to answer are:

Read more

Does the use of the hand and foot mask reduce the severity of symptoms associated with chemotherapy-induced peripheral neuropathy (CIPN) or diabetic peripheral neuropathy (DPN)?

Does the application of the masks improve patient quality of life and treatment compliance for those undergoing chemotherapy?

Participants will:

Complete an initial assessment questionnaire on Day 1.

Apply hand and foot masks daily for 5 minutes, for 7 consecutive days.

Complete a follow-up questionnaire on Day 7 to assess the effects of one week of use.

Currently receiving or having previously received chemotherapy.

Demonstrating clinical signs and symptoms of chemotherapy-induced peripheral neuropathy.

Diabetic Peripheral Neuropathy (DPN) group:

Read the detailed description

Peripheral neuropathy (PN) is a condition characterized by damage or dysfunction of the peripheral nerves, leading to sensory, motor, or autonomic impairments. Symptoms often include numbness, tingling, burning sensations, muscle weakness, and paresthesia. Chemotherapy-induced peripheral neuropathy (CIPN) and diabetic peripheral neuropathy (DPN) are two of the most prevalent causes of PN. Current pharmacological treatments, such as analgesics, anticonvulsants, antidepressants, and opioids, often provide limited efficacy and are frequently associated with significant adverse effects.

Study Rationale and Mechanism of Action:

The "Speedell" hand and foot mask is a novel product formulated to act primarily as a TRPM8 activator. TRPM8 is a non-selective cation channel with six transmembrane domains, widely expressed in human nerve cells. Upon activation by temperatures between 8-28°C or by specific agonists, TRPM8 generates cold signals that are transmitted to the somatosensory cortex.

Scientific literature suggests that the activation of TRPM8-whether by agonists or moderate cooling-induces the release of glutamate at central synapses. This glutamate subsequently activates inhibitory group II/III metabotropic glutamate receptors (mGluRs) located on injured nociceptive afferent neurons or postsynaptic receptors in the dorsal horn, thereby attenuating neuropathic hypersensitivity.

Furthermore, Speedell is designed to deliver natural cooling agents efficiently to the extremities, where they interact with TRPM8 receptors to provide immediate sensory relief. Evidence suggests that these components may contribute to the reduction of tissue damage caused by cellular inflammation. This pilot study aims to clinically validate the efficacy of the Speedell hand and foot mask in alleviating neuropathic discomfort and improving quality of life in patients suffering from chemotherapy-induced or diabetic peripheral neuropathy.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QOL-DN) Score

    The Norfolk QOL-DN is a validated instrument to assess the quality of life in patients with diabetic neuropathy. Scores range from 0 to 4 for each item, where 0 indicates "not at all" and 4 indicates "very much." A change in the total score will be calculated to measure the impact of the intervention.

    Measured: From baseline (Day 1) to the end of the treatment (Day 7).

  2. Change in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-CIPN20) Score

    The EORTC QLQ-CIPN20 is a specialized module for assessing chemotherapy-induced peripheral neuropathy symptoms. Scores range from 0 to 3 for each item, where 0 indicates "not at all" and 3 indicates "very much." A change in the total score will be calculated to measure the impact of the intervention.

    Measured: From baseline (Day 1) to the end of the treatment (Day 7).

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QOL-DN) Score (time frame: From baseline (Day 1) to the end of the treatment (Day 7).). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07583797, which also lists 10 linked publications.

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 15 May 2026; AzTrials last refreshed its copy on 28 Oct 2026.
