What this trial studies

This Phase III, randomized, open-label, multicenter trial randomly assigns eligible patients 1:1 to receive either TQB2102 injection or the combination of docetaxel with trastuzumab and pertuzumab. Participants must have HER2-positive recurrent or metastatic invasive breast cancer, ECOG performance status 0–1, at least one measurable lesion by RECIST 1.1, and adequate organ function, with limited prior systemic therapy in the metastatic setting. The active control arm uses an established standard regimen, and the trial is conducted at multiple hospital sites in China. The primary goal is to compare clinical outcomes and safety between the two treatment arms in a real-world clinical setting.

Who should consider this trial

Good fit: Adults aged 18–75 with confirmed HER2-positive recurrent or metastatic breast cancer, ECOG 0–1, at least one measurable lesion, good organ function, and limited prior systemic therapy in the metastatic setting are the ideal candidates.

Not a fit: Patients with active central nervous system metastases or spinal cord compression, those whose only target lesions are skin or brain, people with poor organ function, or those heavily pretreated in the metastatic setting are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, TQB2102 could provide an effective alternative to the current trastuzumab–pertuzumab–docetaxel combination and may offer differences in efficacy, tolerability, or convenience for patients.

How similar studies have performed: Regimens combining trastuzumab and pertuzumab with chemotherapy have shown clear survival benefit in HER2-positive metastatic breast cancer (for example, the CLEOPATRA results), while TQB2102 represents a novel agent being directly compared to that established standard.
