Trial summary

Taxane neuropathy is a common and long-term side effect of long-term morbidity in patients surviving cancer. No preventive or symptomatic treatment has been shown to be effective. Its pathophysiology is poorly known and probably multifactorial. Read more about this study

About this study

Taxane neuropathy is a common and long-term side effect of long-term morbidity in patients surviving cancer. No preventive or symptomatic treatment has been shown to be effective. Its pathophysiology is poorly known and probably multifactorial. A possible mechanism would be mediated by the activation of the SK3 calcium channel: a retrospective study carried out at the University Hospital of Tours (Carina RUA) found a significant association between the number of CAG triplets in the KCNN3 gene coding for the SK3 channel and the appearance of a taxane neuropathy.

Read the detailed description

Patients hospitalized in medical oncology day hospital at the University Hospital of Tours or CHC oncology day hospital, for their chemotherapy with taxanes (paclitaxel or docetaxel) for breast or prostate cancer, will be offered the study.

The mode of administration of chemotherapy and the usual follow-up will not be modified by the protocol The determination of the SK3 status will be made from an additional tube collected during a collection as part of the treatment at the first arrival in a day hospital (no more blood tests). Blood sample of 7mL. Shipments and analyzes of samples in Tours in the pharmacogenetics laboratory under the responsibility of Dr. BARIN-LE GUELLEC.

This study is non-invasive, without impact on the therapeutic management. The result of the polymorphism of SK3 will not be indicated in the record, so as not to influence the follow-up of the treatment and to allow an evaluation of the occurrence of peripheral neuropathy in blindness of the number of repetitions of the CAG triplet of the KCNN3 gene.

What is being measured

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

  1. Appearance of a neuropathy secondary to taxanes using Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE)

    Evaluation of neuropathy will be performed using non-invasive test, gold standard, Cancer Institute Common Terminology Criteria for Adverse Events

    Grading (from best to worst) :

    0 = normal

    1. = slight paresthesia, mild weakness (subjective)
    2. = moderate paresthesia, moderate weakness (objective)
    3. = severe paresthesia with functional disability, severe weakness
    4. = paralysis

    Measured: From baseline and up to 4 months of follow-up

  2. Appearance of a neuropathy secondary to taxanes using Total neuropathy score clinical (TNSc)

    Evaluation of neuropathy will be performed using non-invasive test, Total neuropathy score clinical

    Grading (from best to worst) :

    Sensory symptoms : 0 = none (N), 1 = symptoms limited finger or toes, 2 = Symptoms extend to ankle or wrist, 3 = Symptoms extend to knee or elbow, 4 = Symptoms above knees or elbow or functionally disabling Motor symptoms : 0 = N, 1 = slight difficulty, 2 = moderate difficulty, 3 = require help/assistance, 4 = paralysis Autonomic symptoms : 0 = N, 1 , 2, 3, 4 (number of symptoms) Pin sensibility and vibration sensibility : 0 = normal (n), 1 = reduced in fingers/toes, 2 = reduced to wrist/ankle, 3 = reduced to elbow/knee, 4 = reduced to above elbow/knee Strength : 0 = n, 1 = mild weakness, 2 = moderate weakness, 3 = severe weakness, 4 = paralysis Deep tendon reflexe : 0 = n, 1 = ankle reflex reduced, 2 = ankle reflex absent, 3 = ankle reflex absent, other reduced, 4 = all reflexes absent

    Measured: From baseline and up to 4 months of follow-up

Secondary outcomes (1)
  1. Occurence of adverses events to taxanes (dysgeusia, myalgia, digestive toxicity tearing, onycholysis.)

    Each adverse event will be evaluated using CTCAE score grading (from best to worst) :

    • 0 : none
    • 1 : minimal
    • 2 : moderate
    • 3 : severe
    • 4 : very severe

    Measured: From baseline and up to 4 months of follow-up

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Chemotherapy-induced Peripheral Neuropathy, run by University Hospital, Tours at 2 sites in France.

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 11 inclusion and 2 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: finished, as of the sponsor's last update on 28 Apr 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in France. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Appearance of a neuropathy secondary to taxanes using Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) (time frame: From baseline and up to 4 months of follow-up). 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?
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 28 Apr 2021.
