About

Study hypothesis is that aprepitant is more effective than desloratadine in relieving pruritus caused by EGFR TKIs. Primary endpoint is the effective rate of pruritus, effective treatment defined as visual analogue scale (VAS) decrease ≥ 50% after treatment compared to baseline score. 130 NSCLC patients undertaken EGFR-TKI and suffer from moderate or severe pruritus (VAS score ≥ 4) will be enrolled in this study, and stratified (gender, VAS 4-6 or 7-10, and 2nd generation TKI or non 2nd generation) randomized (1:1) into aprepitant or desloratadine treatment. VAS investigation will be taken once a week to treatment end (4 weeks).

Full description

This is a prospective, randomized control, double-blinded, phase II clinical trial. Study hypothesis is that aprepitant is more effective than desloratadine in relieving pruritus caused by EGFR TKIs. Primary endpoint is the effective rate of pruritus, effective treatment defined as visual analogue scale (VAS) decrease ≥ 50% after treatment (1 week) compared to baseline score. The VAS inquiry will be taken once a week for 4 weeks. Quality of life investigation will be performed at baseline, 1 week and 4 weeks after treatment using SKINDEX-16 questionnaire. 130 NSCLC patients undertaken EGFR-TKI and suffer from moderate or severe pruritus (VAS score ≥ 4) will be enrolled in this study, and stratified (gender,and VAS 4-6 or 7-10, and 2nd generation TKI or non 2nd generation) randomized (1:1) into aprepitant or desloratadine treatment. Aprepitant arm will be administrated aprepitant 125mg d1, 80mg d3 and d5, along with placebo 5mg d1-d28; desloratadine arm will be administrated placebo 125mg d1, 80mg d3 and d5, along with desloratadine 5mg d1-d28. Tolerance evaluation will be taken according to National Cancer Institute (NCI)-Common Terminology Criteria (CTC) For Adverse Events (AE) V4.03.
