1094 Background: There is increasing evidence that women with HER2-positive metastatic breast cancer (MBC) benefit from continued trastuzumab (H) therapy beyond disease progression (PD). In a Phase II multicentre 2-step trial we evaluated women for their response to second-line treatment with H + vinorelbine (N) following PD after receiving first-line H + taxane for HER2-positive MBC. Methods: Women aged =18 years with HER2-positive MBC received H (8 mg/kg loading dose followed by 6 mg/kg q3w or 4 mg/kg loading dose followed by 2 mg/kg qw) + N (30 mg/m2 days 1 and 8 q3w) until PD. The primary end point was overall response rate (ORR); secondary end points included time to progression, time to treatment failure, overall survival and safety. Data from a planned interim analysis are presented. Results: Seventeen out of a planned 50 patients (pts) were enrolled between June 2003 and October 2006, with a mean age of 54 years (range 42–70). Nine pts had hormone receptor-positive disease at baseline and 17 pts had HER2-positive disease (16 pts IHC 3+; 1 pt IHC 2+ and CISH+). Pts had previously received H in combination with paclitaxel (9 pts) or docetaxel (8 pts) as first-line therapy for MBC. Pts received a median of 6 treatment cycles with H + N (range 2–14), with 2 pts receiving H q3w and 15 pts receiving H qw. ORR was 29%, with 2 pts showing a complete response, 3 pts experiencing a partial response and 4 pts achieving stable disease lasting 6 months. Eight pts experienced PD. Re-treatment with H + N was well tolerated beyond PD, with grade 3/4 haematological toxicities being the most common serious adverse events, leading to a delay and dose reduction of N. No relevant cardiac toxicities were reported, with only 2 grade 1 cardiac events. All pts withdrew, 14 due to PD. Conclusions: This interim analysis indicates that treatment with Herceptin plus chemotherapy beyond PD is active (ORR 29%) and well tolerated, and provides further evidence that re-treatment with H is a promising therapeutic option. Pt accrual is ongoing and updated results will be presented. No significant financial relationships to disclose.

Background: The aim of this project was to provide an expert opinion regarding anti-human epidermal growth factor receptor 2 (HER2) therapy beyond second-line treatment of metastatic breast cancer (mBC). Methods: A group of experts discussed specific issues concerning anti-HER2 therapy in late-line settings in mBC. Results: Trastuzumab emtansine (T-DM1) or dual HER2 blockade appeared to be good options for HER2-positive mBC after ≥ 2 HER2-targeted therapies. Once an objective response has been achieved with anti-HER2-containing therapy, the anti-HER2 agent can be continued until progression of the disease, unacceptable toxicity or patient decision. mBC treated with ≥ 3 consecutive lines of anti-HER therapy, ≥ 1 being a dual HER2 blockade and with early progression of disease during a fourth or later-line treatment, are clinically resistant to anti-HER therapy. For progression of metastasis in the brain after anti-HER2 therapy, lapatinib and chemotherapy appear to be a good alternative after best local treatment. Conclusions: Further clinical trials are needed to provide valuable knowledge about the best treatment options in the later settings of mBC.

Abstract Background The trastuzumab biosimilar MYL-1401O has demonstrated equivalent efficacy and comparable safety to reference trastuzumab (RTZ) in clinical trials of human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) as non-dual HER2 therapy. Here, we present the first real-world comparison of MYL-1401O versus RTZ with single/dual HER2-targeted therapy for the neoadjuvant, adjuvan and palliative first-/second-line treatment with HER2-positive early breast cancer (EBC) and metastatic breast cancer (MBC) patients in two tertiary hospitals in Turkey. Methods We retrospectively investigated medical records in the Severance Breast Cancer Registry in Turkey. We identified patients with HER2-positive EBC (n=159) who had received neoadjuvant chemotherapy (n= 92) with RTZ or MYL-1401O±pertuzumab and adjuvant chemotherapy (n=67) with RTZ or MYL-1401O plus taxan between january 2018 and jun 2021. Stage IV MBC (n=53) who had received palliative first-line treatment with RTZ or MYL-1401O, and docetaxel±pertuzumab (THP) or second-line treatment with RTZ or MYL-1401O, and taxan between january 2018 and jun 2021. Primary endpoints were pathological complete response in neoadjuvant grup (pCR) and progression-free survival (PFS) in adjuvant and metastatic grup. Secondary endpoints in the metastatic patient group (MBC) was overall response rate (ORR), disease control rate (DCR) and cardiac safety. Results The rate of achieving pCR in the group receiving neoadjuvant chemotherapy was similar between MYL and RTZ (62.7% [37/59] and 55.9% [19/34] p=0.509). Median PFS similar in EBC-adjuvant group, 12-24-36 months PFS respectively 96.3%, 84.7%, 71.5% in patients with MYL and 100%, 88.5%, 64.8% in patients with RTZ (95% CI p=0.577). Median PFS similar in metastatic group, 23.0 (9.8-16.1) months in patients with MYL-1401O and 23 (19.9-26.0) months in patients with RTZ (95% CI p=0.270). The ORR, DCR, and cardiac safety profiles did not also show significant difference efficacy outcomes between two groups. Conclusion These real-world data suggest that biosimilar trastuzumab MYL-1401O has similar effectiveness and cardiac safety to RTZ in HER2-positive EBC and MBC patients when administered as part of single/dual HER2-targeted therapy with chemotherapy in the neoadjuvant, adjuvant or palliative setting.
