QL1701 (a proposed trastuzumab biosimilar) versus reference trastuzumab plus docetaxel as first-line therapy for HER2-positive metastatic breast cancer: a multicenter, randomized, double-blinded, parallel-controlled, phase III equivalence trial.

ABSTRACT:

Background

QL1701 is a proposed biosimilar to the reference trastuzumab (Herceptin®). This trial compared the efficacy and safety of QL1701 with the reference trastuzumab in first-line treatment of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer.

Materials and methods

This randomized, double-blinded, parallel-controlled, phase III equivalence trial was conducted in 73 centers in China. Eligible patients with histologically or cytologically diagnosed HER2-positive metastatic breast cancer were randomly assigned (1 : 1) to receive either QL1701 or reference trastuzumab in combination with docetaxel (every 3 weeks) for eight cycles as the first-line treatment. Then, in patients with objective responses or stable disease, the QL1701 or reference
