About this study

Neurotoxic chemotherapy, including oxaliplatin, are responsible for very disabling neuropathic pain that can last for months or even years after the end of chemotherapy. Currently, there is no effective neuroprotective treatment to prevent or relieve this pain. The only strategy is the reduction of oxaliplatin doses or premature discontinuation of therapy, with the risk of burdening the prognosis for remission. Thus, a better understanding of the pathophysiology of these iatrogenic neuropathies appears necessary in order to discover new potential therapeutic targets.

Preclinical works were able to demonstrate important metabolic changes in certain brain structures in an animal model of oxaliplatin-induced neuropathy. A significant increase of choline concentration has been found in the posterior insular cortex of neuropathic animals compared with control animals. Furthermore, the concentrations of choline were positively correlated to nociceptive thresholds. Thus, neuropathic pain induced by oxaliplatin would involve the posterior insular cortex and would be associated with an increase in choline concentration at this level. Clinical translation of these preclinical results is feasible in practice since choline concentration can be determined in the brain by non-invasive magnetic resonance spectroscopy.

Read the detailed description

The objective of this study is to demonstrate a significant increase in choline concentration in the insular cortex of patients with an oxaliplatin induced neuropathy. Other objectives will assess the correlation between metabolite concentrations in the insular cortex and frequency / intensity of pain and neuropathic symptoms, cold and heat-induced pain and comorbidities (anxiety, pain, quality of life).

Questions about this trial

What is this clinical trial studying?

A study testing NMR Spectroscopy in people with Neuropathy and Painful, run by University Hospital, Clermont-Ferrand at 1 site 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 15 inclusion and 18 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 14 Jan 2022. 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 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?

Choline concentration assessed by NMR spectroscopy in the posterior insula (time frame: 1 month after chemotherapy end). 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 14 Jan 2022.
