Summary

This is a multicentre, randomized, double-blind, parallel-controlled integrated phase I/III clinical study to evaluate the similarity in efficacy, safety, PK profile, and immunogenicity of HLX17 vs. Keytruda®( US- and EU-sourced) in the first-line treatment of advanced non-squamous non-small cell lung cancer.

Detailed description

This study includes three treatment groups. Patients will be randomly assigned at a 2:1:1 ratio to the HLX17, US-sourced Keytruda® and EU-sourced Keytruda® group to receive the treatment of IMPs in combination with Carboplatin Plus Pemetrexed until disease progression, initiation of new anti-tumor therapy, withdrawal of informed consent form, death, unacceptable toxicity, or up to 17 cycles (whichever occurs first).

Conditions

• Non-Squamous Non-Small Cell Lung Cancer

Interventions

Type	Name	Description
DRUG	HLX17	HLX17 will be administered as IV infusion at a dose of 200mg on Day 1 of each 21-day cycle in combination with Carboplatin and Pemetrexed until loss of clinical benefit or up to 1 year.
DRUG	US-sourced Keytruda®	US-sourced Keytruda® will be administered as IV infusion at a dose of 200mg on Day 1 of each 21-day cycle in combination with Carboplatin and Pemetrexed. After 24 weeks, all subjects in the US-Keytruda® group will receive HLX17 in combination with Pemetrexed until loss of clinical benefit or up to 1 year.
DRUG	EU-sourced Keytruda®	EU-sourced Keytruda® will be administered as IV infusion at a dose of 200mg on Day 1 of each 21-day cycle in combination with Carboplatin and Pemetrexed until loss of clinical benefit or up to 1 year.
