Summary

A Randomized, Double-blind, Multi-center, Phase III Clinical Study of AK112 or Placebo Combined With Pemetrexed and Carboplatin in Patients With EGFR-mutant Locally Advanced or Metastatic Non-squamous Non-small Cell Lung Cancer Who Have Progressed on or Following Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI) Treatment (HARMONi)

Detailed description

The trial will be performed as a randomized, Double-Blind, Multicenter trial to compare Ivonescimab (SMT112 /AK112) Plus Pemetrexed and Carboplatin to Placebo Plus Pemetrexed and Carboplatin in Patients with Locally Advanced or Metastatic Non-Squamous Non-Small Cell Lung Cancer (NSCLC) Harboring. Approximately 420 subjects will be randomized to two treatment arms at the ratio of 1:1. Each enrolled subject will receive an intravenous infusion of the Ivonescimab (SMT112 /AK112)/Placebo Plus Pemetrexed and Carboplatin (Q3W,up to 4 cycles) in treatment periods per the randomization schedule. Afterward, Ivonescimab (SMT112 /AK112)/ Placebo Plus Pemetrexed will be used for maintenance treatment (administered on Day 1 of each cycle, Q3W) up to 2 years.
