About this study

Official title: A Randomized, Double-blind, Multi-center, Phase III Study of AK112 Combined With Pemetrexed and Carboplatin Versus Placebo Combined With Pemetrexed and Carboplatin in Patients With Locally Advanced or Metastatic EGFR-mutant Non-squamous NSCLC Who Have Failed Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors (EGFR-TKIs)

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 Failed to Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI) Treatment

Read the detailed description

The trial will be performed as a randomized, Double-Blind, Multicenter trial to compare 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 320 subjects will be randomized to the two treatment at the ratio of 1:1. Each enrolled subject will receive an intravenous infusion of the AK112/Placebo Plus Pemetrexed and Carboplatin （Q3W,up to 4 cycles）in treatment periods per the randomization schedule. Afterward, AK112/ Placebo Plus Pemetrexed will be used for maintenance treatment (administered on Day 1 of each cycle, Q3W) up to 2 years.

Being tested
Ivonescimab (SMT112 or AK112) Injection, Placebo Injection

  4. DoR

    Duration of response (DoR), which is defined as the duration from the first documentation of objective response to the first documented disease progression or death due to any cause, whichever occurs first.

    Measured: Up to 2 years

  5. TTR

    TTR is defined as the time to response base on RECIST v1.1

    Measured: Up to 2 years

  6. PFS

    PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first assessed by investigator Per RECIST 1.1.

    Measured: Up to 2 years

  7. AE

    Incidence and severity of adverse events (AEs) and serious adverse events (SAEs), and clinically significant abnormal laboratory results.

    Measured: From the subject signs the ICF to 30 days (AE) and 90 days (SAE) after the last dose of study treatment or initiation of other anti-tumor therapy, whichever occurs first,up to 2 years

  8. Observed concentrations of AK112

    The endpoints for assessment of PK of AK112 include serum concentrations of AK112 at different timepoints after AK112 administration

    Measured: through study completion, an average of 2 year

  9. Number of subjects who develop detectable anti-drug antibodies (ADAs)

    The immunogenicity of AK112 will be assessed by summarizing the number of subjects who develop detectable antidrug antibodies (ADAs)

    Measured: From first dose of AK112 through 90 days after last dose of AK112,up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ivonescimab (SMT112 or AK112) Injection in people with Non-Squamous Non-small Cell Lung Cancer, run by Akeso at 1 site 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 10 inclusion and 15 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: under way, not looking for participants, as of the sponsor's last update on 4 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 phase mean?

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?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival (PFS) (time frame: Up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05184712, which also lists 2 linked publications.

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 4 Mar 2026; AzTrials last refreshed its copy on 7 Nov 2026.
