Official title
A Prospective Study Assessing Neurological Function and Its Clinical Implications in Patients With Locally Advanced or Metastatic Urothelial Carcinoma Receiving Enfortumab Vedotin-Based Therapy
Overview
This prospective observational study aims to evaluate the correlation between neurological function and patient-reported symptoms of peripheral neuropathy (PN) in patients with locally advanced or metastatic urothelial carcinoma (la/mUC) receiving enfortumab vedotin (EV)-based therapy. A total of 100 patients will be enrolled between March 2025 and December 2029. Eligible participants will undergo comprehensive neurological assessments, including neurological examination(NE), nerve conduction study (NCS), quantitative sensory testing (QST), autonomic function testing (AFT), and the Toronto Clinical Neuropathy Score (TCNS) questionnaire. These assessments will be conducted at baseline and every three months until six months after completion of EV-based therapy. Patient characteristics and oncological outcomes will also be collected. This study seeks to identify risk factors for developing PN and to explore the clinical implications of EV-associated neurological changes, with the ultimate goal of optimizing treatment strategies and improving quality of life.
Detailed description
Peripheral neuropathy (PN) is a frequent and often debilitating adverse event associated with enfortumab vedotin (EV), a NECTIN-4-directed antibody-drug conjugate approved for patients with locally advanced or metastatic urothelial carcinoma (la/mUC). While EV has demonstrated significant antitumor efficacy, the objective assessment of PN and its clinical implications remain insufficiently explored. This prospective observational study aims to comprehensively evaluate neurological function and its correlation with subjective PN symptoms in la/mUC patients receiving EV-based therapy.
A total of 100 patients will be prospectively enrolled between March 2025 and December 2029. Neurological assessments will include neurological neurological examination (NE), nerve conduction study (NCS), quantitative sensory testing (QST), autonomic function testing (AFT), and the Toronto Clinical Neuropathy Score (TCNS) questionnaire. These evaluations will be conducted at baseline and every three months until six months post-EV treatment. Clinical data, including patient characteristics and oncologic outcomes, will also be collected.
This study aims to identify predictive factors for EV-related PN and to evaluate the broader clinical implications of neurological function changes. The ultimate goal is to inform strategies for toxicity mitigation and to optimize therapeutic outcomes and quality of life in la/mUC patients.
Interventions
- Diagnostic test Neurological function assessment
Neurological evaluations including neurological examination (NE), nerve conduction study (NCS), quantitative sensory testing (QST), autonomic function testing (AFT), and the Toronto Clinical Neuropathy Score (TCNS) questionnaire. Assessments will be conducted at baseline and every three months until six months after completion of EV treatment.
Primary outcome measures
- Correlation between neurological function and subjective peripheral neuropathy symptoms [Time frame: Baseline to 6 months post-treatment.]
Secondary outcome measures (1)
- Correlation between neurological function changes and oncological outcomes [Time frame: From date of EV initiation to the date of death from any cause, assessed up to 36 months]
Eligibility criteria
