Summary

The study is a Phase III, randomized, multicenter, open-label study in HER2-low, HR+ metastatic breast cancer subjects who are patients with locally advanced or metastatic breast cancer with low HER2 expression in the recurrent metastatic stage who have not received chemotherapy. The primary objective of the study is to determine the efficacy and safety of TQB2102 compared to investigator-selected single-agent chemotherapy in the target population. 542 subjects with HER2 immunohistochemistry (IHC )2+/ in situ hybridization (ISH)- and IHC 1+ (HER2-low) expression will be enrolled in 1:1 randomized groups to receive TQB2102 or investigator's choice of single-agent chemotherapy (capecitabine, paclitaxel, or albumin-paclitaxel) until progression of disease (PD), as defined by Response Evaluation Criteria in Solid Tumors (RECIST) 1. 1, unless there are unacceptable toxicity, withdrawal of consent, or meeting other discontinuation criteria.

Conditions

Interventions

DRUG

TQB2102 for Injection

TQB2102 is a next-generation HER2 Antibody-Drug Conjugate (ADC) drug proposed for patients with HER2 low-expressing breast cancer.

DRUG

Chemotherapy drug (Capecitabine/Paclitaxel/Albumin Paclitaxel)

Based on each patient's condition and previous treatment history, the investigator will select one of the chemotherapy drugs for treatment. * Capecitabine: 1000-1250 mg/m2 twice daily, administered consecutively on day 1-14, 21 days as a treatment cycle. * Paclitaxel: 175 mg/m2, IV infusion, administered Day1 per cycle, 21 days as a treatment cycle. OR 80 mg/m2 by IV infusion administered weekly. * Albumin Paclitaxel: 260 mg/m2, IV infusion, administered every cycle of Day1 for 21 days as a treatment cycle. 100 mg/m2 or 125 mg/m2, IV infusion, administered every cycle of Day 1 and Day 8 for 21 days as a treatment cycle; or Day 1, Day 8, and Day 15 administered every cycle for 28 days as a treatment cycle.
