Personalized Antiemetic Regimen According to Patients' Pharmacogenetic Profile

Официальное название

Randomized Phase II Study of Personalized Antiemetic Regimen Based on Pharmacogenetic Profile for the Prevention of Chemotherapy-Induced Nausea and Vomiting in Chinese Breast Cancer Patients.

Обзор

The objectives of this study are to determine if pharmacogenetic (PG) analysis of an individual enable optimal selection of antiemetic regimen for patients undergoing the first cycle of AC (Adriamycin + Cyclophosphamide) or FEC (Fluorouracil + Epirubicin + Cyclophosphamide) chemotherapy. It also aims to compare the quality of life of patients in the first cycle of AC / FEC chemotherapy with and without PG analysis. Patients will be randomized to undergo PG analysis \[PG group\] versus no PG analysis \[Non-/+PG group\]. Those in the PG group would be offered currently available optimal antiemetic prophylaxis, with or without Olanzapine according to PG outcomes. Those in the Non-PG group would be offered currently available optimal antiemetic prophylaxis.
