A Phase 1 Clinical Trial of TQB2102 for Injection in Patients With Human Epidermal Growth Factor Receptor 2 (HER2) -Expressing Relapsed/Metastatic Breast Cancer
TQB2102 is an antibody-drug conjugate comprised of a humanised antibody against Human Epidermal Growth Factor Receptor 2 (HER2), an enzyme-cleavable linker, and a topoisomerase I inhibitor payload, which combine the ability of antibodies to specifically target tumour cells with the highly potent killing activity of drugs with payloads too toxic for systemic administration. This is a Phase 1/Phase 2 study to evaluate the effectiveness, safety, pharmacokinetics (PK) and anti-drug antibody (ADA) of TQB2102 for injection in subjects with HER2-expressing relapsed/metastatic breast cancer.

• Disease progression or intolerance during or after the most recent treatment period must be present before participating in clinical trials;
• At least one measurable lesion (based on Response Evaluation Criteria In Solid Tumors 1.1);
• The main organs function are normally;
• Female participants of childbearing age should agree to use contraception during the study period and for 6 months after the end of the study; Have a negative serum pregnancy test within 7 days prior to study enrollment and must be a non-lactating subject; Male participants should agree that contraception must be used during the study period and for 6 months after the end of the study period.
