Adding capivasertib to fulvestrant improves the progression-free survival (PFS) in postmenopausal women with oestrogen receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative, advanced breast cancer resistant to aromatase inhibitors, concluded Jones et al. (2020) in Lancet Oncology.
Adding capivasertib to paclitaxel improved the progression-free survival (PFS) in patients with metastatic triple-negative breast cancer (TNBC) who had not received prior treatment for metastatic disease. Predominantly patients with PIK3CA/AKT1/PTEN-altered tumours had a more pronounced PFS and overall survival (OS) benefit, as reported by Schmid et al. in the Journal of Clinical Oncology
In patients with hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer, adding ribociclib to fulvestrant improved the overall survival (OS) by 28% compared to fulvestrant alone, as reported by Slamon et al. (2019) in The New England Journal of Medicine.
On 4 April 2019, the US FDA approved palbociclib (Ibrance®, Pfizer) plus aromatase inhibitor or fulvestrant for the treatment of male patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer.
On 8 March 2019, the FDA granted accelerated approval to atezolizumab (Tecentriq®, Genentech/Roche) in combination with albumin-bound paclitaxel (nab-paclitaxel) for the treatment of adult unresectable locally advanced or metastatic triple-negative breast cancer (TNBC) patients with programmed death 1 ligand (PD-L1) stained tumour-infiltrating immune cells (IC) of any intensity covering ≥1% of the tumour area, as determined by the VENTANA PD-L1 (SP142) Assay companion diagnostic (CDx).
On 28 February 2019, the FDA approved the subcutaneous formulation trastuzumab/hyaluronidase-oysk (Herceptin Hylecta®, Genentech) for the treatment of human epidermal growth factor receptor 2 (HER2)‑overexpressing breast cancer.
On 18 January 2019, the FDA approved the Herceptin®-biosimilar Ontruzant® (trastuzumab-dttb, Samsung BioEpsis), a HER2/neu receptor antagonist, for patients with HER2-overexpressing (HER2+) breast cancer in the adjuvant and metastatic setting, and in metastatic HER2+ gastric cancer patients. Ontruzant® was approved as biosimilar, not as an interchangeable product.
On 14 December 2018, the FDA approved the Herceptin®-biosimilar Herzuma® (trastuzumab-pkrb, Celltrion), a HER2/neu receptor antagonist, for patients with HER2-overexpressing (HER2+) breast cancer. Herzuma® was approved as biosimilar, not as an interchangeable product.
Single-agent PARP-inhibition with talazoparib is associated with an improved progression-free survival (PFS) and better patient-reported outcomes (PRO) when compared to chemotherapy alone in patients with advanced breast cancer (ABC) and a germline BRCA1/2 mutation, as reported by the investigators of the Phase III EMBRACA study (NCT01945775) in the New England Journal of Medicine.
