About this study
Official title: Evaluation of the Efficacy and Safety of Trastuzumab Rezetecan(SHR-A1811) Combined With Ivonescimab (AK112) in Locally Advanced or Metastatic Non-small Cell Lung Cancer With HER2 Gene Abnormalities in a Phase II Clinical Trial
This is a phase II trial in patients with locally advanced or metastatic non-small cell lung cancer harboring HER2 gene abnormalities （amplification or overexpression）with a performance status of 0 to1 who are planned to receive first-line treatment or who have falied the first-line treatment
Read the detailed description
This is a Phase II study aimed at evaluating the efficacy and safety of Trastuzumab Rezetecan (SHR-A1811) combined with ivonescimab (AK112) in the treatment of locally advanced or metastatic non-small cell lung cancer (NSCLC) with HER2 gene abnormalities (amplification or overexpression). The study was divided into two cohorts: Cohort 1 included patients with HER2 amplification or overexpression who had failed first-line treatment; Cohort 2 included patients with HER2 amplification or overexpression who were diagnosed for the first time and had PD-L1 expression ≥ 1%. All eligible patients received intravenous administration of SHR-A1811 at 4.8 mg/kg combined with AK112 at 20 mg/kg, once every 3 weeks. The primary endpoint was the progression-free survival (PFS) evaluated by the investigators according to RECIST v1.1; secondary endpoints included duration of response (DOR), objective response rate (ORR), overall survival (OS), and safety indicators (adverse events, serious adverse events, etc.).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Trastuzumab Rezetecan and ivonescimab in people with Non Small Cell Lung Cancer, run by Sun Yat-sen University 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 11 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 5 Jun 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Progression free survival (time frame: assessed up to 36 months). 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 5 Jun 2026; AzTrials last refreshed its copy on 8 Nov 2026.
