March 18, 2026 updated by: Li Zhang, MD, Sun Yat-sen University

A Phase II Clinical Trial to Evaluate the Efficacy and Safety of SHR-A1811 Combined With Ivonescimab (AK112) in Locally Advanced or Metastatic Non-Small Cell Lung Cancer With HER2 Abnormalities

This is a phase II, open-label, single-arm study evaluating the efficacy and safety of SHR-A1811 (a HER2-targeted ADC) combined with AK112 (a PD-1/VEGF bispecific antibody) in patients with HER2-amplified or overexpressed locally advanced or metastatic NSCLC.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study consists of two cohorts: Cohort 1 includes patients who failed standard first-line therapy; Cohort 2 includes treatment-naïve patients. Patients will receive treatment with SHR-A1811 and AK112 until disease progression or meeting other criteria for treatment discontinuation, whichever occurs first.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
PFS
Time Frame: From date of first study treatment to the date of first documented disease progression or date of death from any cause, whichever occurs first, assessed up to approximately 36 months.
Progression-free survival (PFS), defined as the time from first study treatment to disease progression or death from any cause, whichever occurs first. Disease progression is assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
From date of first study treatment to the date of first documented disease progression or date of death from any cause, whichever occurs first, assessed up to approximately 36 months.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
DOR
Time Frame: From the date of first documented objective response to the date of first documented disease progression or death from any cause prior to progression, whichever occurs first, assessed up to approximately 36 months.
Duration of response (DOR), defined as the time from the first documented objective response (complete response or partial response) to the first documented disease progression or death from any cause prior to progression, whichever occurs first. Objective response is assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
From the date of first documented objective response to the date of first documented disease progression or death from any cause prior to progression, whichever occurs first, assessed up to approximately 36 months.
