Study Description
Brief Summary
This study will evaluate the efficacy and safety of RC48-ADC for injection in subjects with advanced non-small cell lung cancer with HER2 overexpression or HER2 mutation.

Drug: RC48
Participants will be treated with RC48-ADC at a dose of 2.0 mg/kg, every 2 weeks. They will continue the medication until one of the following conditions occurred: disease progression, intolerance of toxicity, investigators believed that the subject could no longer benefit from treatment, or this study ended.

Outcome Measures
Primary Outcome Measures
- Objective Response Rate （ORR） [15 months]
Objective Response Rate was defined as the percentage of participants with a complete response (CR) or partial response (PR).
- Disease Control Rate (DCR) [15 months]
Disease Control Rate (DCR) was defined as the percentage of patients with advanced or metastatic cancer who have achieved complete response, partial response and stable disease to a therapeutic intervention in clinical trials of anticancer agents.
- Progression Free Survival (PFS) [15 months]
Progression-free Survival (PFS) (median) was determined using the number of months measured from the initial date of treatment to the date of documented progression, or the date of death (in the absence of progression) of participants. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions.
- Duration of Response (DOR) [15 months]
Duration of response is the length of time that a tumor continues to respond to treatment without the cancer growing or spreading.
- Overall Survival (OS) [24 months]
Overall survival, or OS, measures how long patients, who undergo a certain treatment regimen.
Secondary Outcome Measures
- Adverse events (AEs) [Up to 2 years]
The drug safety was assessed by investigator(s) according to NCI-CTCAE v4.03.
Eligibility Criteria
Criteria
Inclusion Criteria:

Exclusion Criteria:
-
Have used T-DM1 or participated in other HER2-ADC clinical studies.
-
Received anti-tumor treatment 4 weeks before study administration, including chemotherapy (late toxicity chemotherapy was 6 weeks before study administration), radiotherapy (palliative local radiotherapy for bone metastases was 2 weeks before the study administration), biological therapy (small molecule targeted drugs were 8 days before the study administration) or immunotherapy, etc.
-
Major surgery was performed within 4 weeks prior to study administration and did not fully recover.
-
Other clinical trial drugs have been used within 4 weeks before the start of study administration.
-
Live vaccine received within 4 weeks before the start of study administration.

-
Toxicity of previous anti-tumor treatment has not recovered to CTCAE (version 4.03) 0-1, except for the following conditions: a. Hair loss; b. Pigmentation; c. Long-term toxicity caused by radiotherapy, which cannot be restored by the judgement of the investigator.
-
