    Efficacy and safety of biosimilar trastuzumab (CT-P6) in routine clinical practice in the Republic of Korea: a real-world post-marketing surveillance study. (PubMed, Expert Opin Biol Ther)
    Among trastuzumab-naïve patients, 34/106 (32.1%) with EBC achieved pathological complete response; 30/74 (40.5%) MBC and 24/49 (49.0%) MGC patients achieved complete or partial response. In a real-world setting, CT-P6 demonstrated safety and efficacy findings consistent with previous CT-P6 studies.

    Biosimilar in Breast Cancer: A Narrative Review. (PubMed, Cureus)
    Trastuzumab biosimilars, such as CT-P6, Ontruzant®, ABP 980, and PF-05280014, have shown efficacy in treating HER2-positive metastatic BCs, presenting a viable alternative to the reference product. Monoclonal biosimilars present a promising avenue in BC therapy, demonstrating efficacy, safety, and potential cost savings. The integration of biosimilars into cancer treatment strategies offers a means to improve accessibility to effective care while addressing economic considerations in healthcare.

    A phase 2 multicenter study of docetaxel-PM and trastuzumab-pkrb combination therapy in recurrent or metastatic salivary gland carcinomas. (PubMed, Cancer)
    Salivary duct carcinoma (SDC) is uncommon but is the most aggressive subtype of salivary gland carcinomas. SDC shares morphological and histological similarities with invasive ductal carcinoma of breast, which led to an investigation of hormonal receptor and human epidermal growth factor receptor 2 (HER2)/neu expression status in SDC. In this study, patients with HER2-positive SDC were enrolled and treated with combination of docetaxel-polymeric micelle and trastuzumab-pkrb. Promising antitumor activities were shown with objective response rate of 69.8%, disease control rate of 93.0%, median progression-free survival of 7.9 months, median duration of response of 6.7 months, and median overall survival of 23.3 months.

    Targeting human EGFR 2 (HER2) in salivary gland carcinoma. (PubMed, Expert Rev Anticancer Ther)
    Conversely, there are prospective trials supporting the use of anti-HER2 therapy in patients with unresectable, recurrent, or metastatic HER2-positive SGC, including trastuzumab plus docetaxel, trastuzumab plus pertuzumab, trastuzumab-pkrb plus nanoxel, trastuzumab emtansine (T-DM1), and trastuzumab deruxtecan (T-Dxd). T-DM1 or T-Dxd can be considered upon disease progression on trastuzumab-combination therapies, although these antibody-drug conjugates can also be used upfront. Future research should investigate predictive biomarkers, the combination of HER2 and androgen blockade, and the application of novel therapies from breast cancer.

Enrichment of HRD related gene mutations and newly detected variants in ctDNA may be related with the study drug resistance.

    Efficacy of CT-P6 (trastuzumab biosimilar) versus reference trastuzumab in combination with pertuzumab in HER2-positive early-stage breast cancer: Preclinical and real-life clinical data. (PubMed, Breast)
    Adding paclitaxel to these treatments increased their effectivity to a similar extent. Moreover, the costs of CT-P6-based treatments were reduced by 1474.07 €/patient. All together we provide pre-clinical and clinical evidence of the equivalence of CT-P6 in combination with pertuzumab and chemotherapy and suggest studying these combinations also in HER2 low/negative BC patients.

    Efficacy and Safety of Trastuzumab Biosimilar (CT-P6) Compared With Reference Trastuzumab in Patients With HER2-positive Advanced Gastric Cancer: A Retrospective Analysis. (PubMed, Am J Clin Oncol)
    Biosimilar trastuzumab showed equivalent outcome to reference trastuzumab, with similar adverse events. Biosimilar trastuzumab can suitably and safely replace trastuzumab as a reference for the treatment of HER2-positive AGC.
