Nerve Excitability in Cisplatin-Induced Peripheral Neuropathy

Официальное название

Evaluation of Nerve Excitability in Cisplatin-Induced Peripheral Neuropathy

Обзор

This study aims to evaluate nerve excitability in participants with cisplatin-induced peripheral neuropathy (cis-PN) using threshold tracking nerve conduction studies (TTNCS). By assessing changes in nerve excitability parameters, the study seeks to enhance understanding of the pathophysiology of cis-PN and identify early markers of neurotoxicity in participants undergoing cisplatin-based chemotherapy.

Подробное описание

This study aims to evaluate nerve excitability in participants with cisplatin-induced peripheral neuropathy (cis-PN) using threshold tracking nerve conduction studies (TTNCS). By assessing changes in nerve excitability parameters, the study seeks to enhance understanding of the pathophysiology of cis-PN and identify early markers of neurotoxicity in participants undergoing cisplatin-based chemotherapy.

Peripheral neuropathy is a sensory disorder where patients feel a burning, tingling, or pins-and-needles sensation in the hands and feet that can lead to oversensitivity or numbness.

The U.S. Food and Drug Administration (FDA) has not approved DS5 0 Isolated Bipolar Constant Current Stimulator as a diagnostic tool for Peripheral Neuropathy.

The research study procedures include screening for eligibility, in-clinic visits, blood tests, questionnaires, and standard neurological exams called nerve conduction studies and Threshold tracking nerve conduction studies.

Participants will be placed into one of the following groups:

* Cohort A: Participants without previous treatment with cisplatin and are about to start treatment with Cisplatin. * Cohort B: Participants with previous treatment with cisplatin in the past 3 months (and no longer being treated with cisplatin) and are currently experiencing cisplatin- induced peripheral neuropathy.

It is expected that about 60 people will take part in this research study.

Вмешательства

• Диагностический тест Threshold Tracking Nerve Conduction Studies
  Measurement of nerve excitability parameters, including response to sub-threshold pre-pulses and other stimuli. The DS5 0 Isolated Bipolar Constant Current Stimulator is a non-invasive, non-therapeutic device that provides controlled electrical stimuli for detailed function assessment of the superficial radial, superficial peroneal, ulnar, and sural nerves.

Первичные конечные точки

• Presence of change in Nerve Excitability in comparison to baseline nerve excitability. [Срок оценки: For Arm A, the time frame is at baseline and within 24 weeks of cisplatin initiation. For Arm B, the time frame is during the TTNCS procedure.]

Вторичные конечные точки (1)

• Number of participants who develop neuropathy symptoms as assessed by CTCAE v. 5.0. [Срок оценки: For Arm A, peripheral neuropathy symptoms will be assessed at baseline and the time of the development of Cis-PN symptoms over the course of 24 weeks. For Arm B, symptoms will be assessed immediately before the TTNCS procedure.]

Критерии участия

Inclusion Criteria Cohort A:

• Adults age ≥ 18 who will begin cisplatin-based chemotherapy either alone or in combination with other agents that are not known to cause neuropathy.
• Participants must have adequate hematologic parameters to allow chemotherapy.

Exclusion Criteria Cohort A:

• Pre-existing peripheral neuropathy;
• Family history of a genetic/familial neuropathy;
• Any contraindication for treatment with cisplatin as determined by their primary oncologist;
• Chemotherapy regimen combining cisplatin with another known chemotherapy agent that may cause peripheral neuropathy;
• Patients with cardiac or spinal stimulating devices;
• Women who are pregnant or breastfeeding;
• Adults with impaired consent capacity as patients must be able to fill out questionnaires regarding their neuropathy symptoms;
• Other medical conditions that in the opinion of the treating physician would make the protocol unreasonably hazardous for the patient;
• Patients not considered to be able to comply with the protocol.

Inclusion Criteria Cohort B:

• Adults age ≥ 18 with a diagnosis of cis-PN.
• The last dose of cisplatin must be ≥ 3 months prior to study enrollment. Patients who may have been previously enrolled in Cohort A of this study are eligible to participate in Cohort B if they continue to have cis-PN symptoms 3 months after completion of cisplatin therapy.

Exclusion Criteria Cohort B:

• Pre-existing peripheral neuropathy;
• Family history of a genetic/familiar neuropathy;
• History of cisplatin-based regimen combining cisplatin with another known chemotherapy agent that may cause peripheral neuropathy;
• Patients with cardiac or spinal stimulating devices;
• Women who are pregnant or breastfeeding;
• Adults with impaired consent capacity as patients must be able to fill out questionnaires regarding their neuropathy symptoms;
• Other medical conditions that in the opinion of the treating physician would make the protocol unreasonably hazardous for the patient;
• Patients not considered to be able to comply with the protocol.
