Overview

This multicenter, prospective phase II clinical trial aims to evaluate the efficacy and safety of medical compression stockings in preventing peripheral neuropathy induced by antibody-drug conjugates (ADCs) containing monomethyl auristatin E (MMAE) in patients with advanced cancers, including urothelial carcinoma. Eligible participants will have no baseline ≥ grade 1 neuropathy and will be scheduled to receive MMAE-containing ADC therapy. A total of 58 patients will be enrolled and followed for 24 months. In this self-controlled design, the left foot will be fitted with a medical compression stocking while the right foot remains uncovered, starting 15 minutes before infusion and continuing until 15 minutes after infusion (total duration: 120 minutes). Peripheral neuropathy will be assessed before treatment, after cycle 3, within 1 week after treatment completion, and 1 month after completion, using CTCAE v5.0 and patient-reported questionnaires (QLQ-C30 and FACT-GOG-NTx). Toe temperature will be measured to assess local microcirculation changes. The study will also monitor compression-related adverse events. The results will provide evidence for preventive strategies to reduce ADC-induced peripheral neuropathy and improve patients' quality of life.

Eligibility

Inclusion Criteria:

• Expected survival ≥ 3 months
• Ability and willingness to comply with study procedures and provide written informed consent

Exclusion Criteria:

• Poor compliance or inability to follow protocol

• Severe psychiatric conditions (depression, bipolar disorder, substance abuse)
• Active uncontrolled infections requiring systemic antibiotics/antifungals/antivirals (≥ CTCAE Grade 2)
• Active hepatitis or significant liver dysfunction not meeting inclusion criteria

• Active tuberculosis or uncontrolled pleural/pericardial effusion/ascites
• Hypersensitivity to monoclonal antibodies or study device components
• Participation in other clinical trials within 4 weeks
• Known bleeding or coagulation disorders or receiving thrombolytic therapy
• Any other condition judged by the investigator to preclude safe participation
