Imfinzi + transarterial chemoembolisation +bevacizumab met primary endpoint for progression-free survival in liver cancer eligible for embolisation in EMERALD-1 phase III trial
Positive high-level results from the EMERALD-1 Phase III trial showed AstraZeneca’s Imfinzi (durvalumab) in combination with transarterial chemoembolisation (TACE) and bevacizumab demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of progression-free survival (PFS) versus TACE alone in patients with hepatocellular carcinoma (HCC) eligible for embolisation
The trial continues to follow the secondary endpoint of overall survival (OS).
The safety profiles for Imfinzi and TACE plus bevacizumab were consistent with the known profile of each medicine, and there were no new safety findings. The data will be presented at a forthcoming medical meeting and shared with regulatory authorities.
AstraZeneca has an extensive clinical development programme further assessing Imfinzi across multiple gastrointestinal (GI) cancer settings, including in combination with bevacizumab in adjuvant HCC (EMERALD-2) and in combination with Imjudo (tremelimumab), lenvatinib and TACE in embolisation-eligible HCC (EMERALD-3).
EMERALD-1: EMERALD-1 is a randomised, double-blind, placebo-controlled, multicentre, global Phase III trial of Imfinzi plus TACE concurrently, followed by Imfinzi with or without bevacizumab until progression versus TACE alone in a total of 616 patients with unresectable HCC eligible for embolisation. The trial was conducted in 157 centres across 18 countries, including in North America, Australia, Europe, South America and Asia. The primary endpoint was PFS for Imfinzi and TACE plus bevacizumab versus TACE alone, and secondary endpoints include PFS for Imfinzi plus TACE, overall survival, patient-reported outcomes and objective response rate.
