About this study
Official title: A Randomized, Double-Blind, Multicenter, Phase II/III Study to Evaluate HLX37 (Recombinant Human Anti-PD-L1 and Anti-VEGF Bispecific Antibody) in Combination With Chemotherapy Versus Pembrolizumab in Combination With Chemotherapy for First-Line Therapy of Advanced Non-Small Cell Lung Cancer
This is a Randomized, Double-Blind, Multicenter, Phase II/III Study to Evaluate HLX37 (Recombinant Human Anti-PD-L1 and Anti-VEGF Bispecific Antibody) in Combination with Chemotherapy Versus Pembrolizumab in Combination with Chemotherapy for First-Line Therapy of Advanced Non-Small Cell Lung Cancer.The first phase of this study is a Phase II trial, with Substudy A enrolling approximately 90 participants and Substudy B enrolling approximately 90 participants. Based on your disease pathology type, the investigator will determine which substudy you are enrolled in. Eligible participants will be randomly assigned to one of three treatment groups in a 1:1:1 ratio (similar to flipping a coin or drawing names from a hat), giving each participant an equal 1/3 chance of being assigned to any given group. Within each substudy, approximately one-third of participants will receive HLX37 at dose1combined with chemotherapy, one-third will receive HLX37 at dose2 combined with chemotherapy, and one-third will receive pembrolizumab at 200 mg combined with chemotherapy. All three treatment groups will have a treatment schedule of every three weeks (Q3W).
The second phase of this study is a Phase III trial, with Substudy A enrolling approximately 820 participants and Substudy B enrolling approximately 618 participants. Again, based on your disease pathology type, the investigator will determine your enrollment into either substudy. Eligible participants will be randomly assigned to one of two treatment groups in a 1:1 ratio (similar to flipping a coin or drawing names from a hat), giving each participant an equal 1/2 chance of being assigned to either group. In each substudy, approximately half of the participants will receive HLX37 at dose selected combined with chemotherapy, and the other half will receive pembrolizumab at 200 mg combined with chemotherapy. Both treatment groups will follow a Q3W treatment schedule.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Investigational drug: HLX37 dose1, IV, Q3W, PEMBROLIZUMAB (alone or when added to a regimen above) and Carboplatin (Investigator discretion) in people with NSCLC (Advanced Non-small Cell Lung Cancer), run by Shanghai Henlius Biotech at 16 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 8 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 16 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Li ya Wan (02122200000, Liya_Wan@henlius.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
PFS assessed by BICR (Phase2&3) (time frame: From date of the first dose of study drug until the date of death from any cause, assessed up to 24 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Oct 2026.
