About the research

The purpose of this study is to evaluate the safety, tolerability and objective response rate of SKB264 as combination with therapy in subjects with advanced or metastatic non-small cell lung cancer.

Who may be able to participate?

The list below is the sponsor’s full registry wording. It can include conditions, prior treatment, test results and other requirements. A match in search does not mean you qualify.

3. Subjects for NSCLC should be confirmed to be EGFR (Epidermal growth factor receptor) wild-type and ALK (Anaplastic lymphoma kinase) fusion gene negative; or confirmed to harbor EGFR mutation;
4. Locally advanced or metastatic NSCLC subjects without actionable EGFR mutations and ALK fusion genes, no prior systemic treatment; subjects with EGFR mutation, no prior systemic treatment or failed prior EGFR-TKI (Tyrosine kinase inhibitor) treatment;
5. Subjects are able to provide tumor blocks or slides before the first dose of study intervention;
6. Subject must have at least one radiographically measurable lesion as per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria;
7. Subject has an Eastern Cooperative Oncology Group (ECOG) performance status of either 0 or 1;

2. Subjects with a known history of prior malignancy;
3. Subjects with known meningeal metastases, brainstem metastases, spinal cord metastases and/or compression, or active central nervous system (CNS) metastases;
4. Subjects with ≥ Grade 2 peripheral neuropathy;
5. Subjects who had arteriovenous thromboembolic events, tumor invasion/encasement of vital organs/vessels, risk of esophageal-tracheal/pleural fistula, or current superior vena cava syndrome;
6. Subjects with active inflammatory bowel disease or previous clear history of inflammatory bowel disease;
7. Subjects who suffer from cardiovascular diseases of clinical significance;
8. Subjects with a history of interstitial lung disease (ILD)/non-infectious pneumonitis that required steroids;
9. Subjects with uncontrolled systemic disease as judged by the Investigator;
10. Subjects with active autoimmune disease that required systemic treatment in the past 2 years;
11. Subjects with active hepatitis B or hepatitis C;
12. Subjects with known history of Human Immunodeficiency Virus (HIV)

Treatment, groups and participation

The registry may describe treatments and study duration without a complete visit calendar. Ask the study team for the exact schedule, procedures, risks, costs and alternatives. Keep your usual care plan unless your treating clinician tells you otherwise.
