HER2陽性轉移性/復發性乳癌:新型療法、未滿足的需求和TPP洞察報告,2026年HER2-Positive Metastatic Breast Cancer - Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026 |

Thelansis 的《HER2 陽性轉移/復發性乳癌:新興治療方法、未滿足的需求和 TPP 洞察報告 - 2026》對該適應症的關鍵新興治療方法和主要藥物發現機會進行了全面分析,包括新興的競爭格局、未滿足的需求、目標產品概況 (TPP)、試驗設計和關鍵意見領袖 (KOL) 的見解。
HER2陽性轉移性或復發性乳癌是一種侵襲性極強的分子亞型,由ERBB2基因擴增引起,導致跨膜蛋白酪氨酸激酶人類表皮生長因子受體2 (HER2) 過度表現。傳統上,它與疾病進展迅速、內臟侵犯率高以及極易發生中樞神經系統(CNS)轉移有關,但標靶治療已顯著改變了其疾病進程。
透過免疫組織化學 (IHC) 或原位雜合反應(ISH) 準確地確定 HER2 狀態對於制定治療策略至關重要。目前的治療模式是基於 HER2標靶治療的階梯式方案,首先採用曲妥珠單抗和Pertuzumab合併化療的雙單株抗體抑制劑治療。
隨著疾病進展,治療方法也隨之發展,引入了新一代抗體藥物複合體(ADC),特別是曲妥珠單抗德魯替康(T-DXd)。 T-DXd 已展現出卓越的療效,並幾乎完全取代了先前的藥物,例如 T-DM1。在後續治療中,尤其是在腦轉移患者中,中樞神經系統(CNS)滲透性的蛋白酪氨酸激酶抑制劑(例如圖卡替尼)在控制全身和顱內病灶方面發揮著至關重要的作用。
Thelansis's "HER2-Positive Metastatic Breast Cancer Emerging Therapy, with Unmet Needs and TPP Insights Report - 2026" provides a comprehensive analysis of the emerging competitive landscape, unmet needs, target product profiles (TPPs), trial designs, and KOL insights on key emerging therapies and key drug development opportunities in the indication.
HER2-positive metastatic breast cancer is a highly aggressive molecular subtype driven by amplification of the ERBB2 gene, resulting in overexpression of the human epidermal growth factor receptor 2 (HER2), a transmembrane tyrosine kinase. Historically associated with rapid disease progression, high visceral involvement, and a strong propensity for central nervous system (CNS) metastases, the disease course has been significantly transformed by targeted therapies.
Accurate determination of HER2 status via immunohistochemistry (IHC) or in situ hybridization (ISH) is essential for guiding treatment. The modern therapeutic paradigm is based on sequential HER2-targeted therapy, beginning with dual monoclonal antibody blockade using trastuzumab and pertuzumab in combination with chemotherapy.
Upon progression, treatment has evolved with the introduction of next-generation antibody-drug conjugates (ADCs), particularly trastuzumab deruxtecan (T-DXd), which has demonstrated superior efficacy and largely replaced earlier agents such as T-DM1. In later lines, especially for patients with brain metastases, CNS-penetrant tyrosine kinase inhibitors (e.g., tucatinib) play a critical role in achieving both systemic and intracranial disease control.
