Filter by:To assess the safety and tolerability characteristics of B003 in HER2-positive patients with recurrent or metastatic breast cancer. The dose-limiting toxicity (DLT) is assessed and the maximum tolerated dose (MTD) is explored.
This study is a single-arm, prospective, open label clinical study for evaluating the efficacy and safety of neoadjuvant pyrotinib and trastuzumab plus Vinorelbine given as neoadjuvant treatment in Trastuzumab-refractory HER2 positive early stage or locally advanced breast cancer.
This is a single-center phase Ⅱ study designed to evaluated the efficacy and safety of pegylated liposomal doxorubicin(PLD)in combination with trastuzumab in HER-2 positive metastatic breast cancer .
This clinical trial aim to evaluate the efficacy and safety of Pyrotinib in combination with nab-paclitaxel in patients with HER2-positive advanced breast cancer.
Survival benefit and quality of life are two key elements that should be kept in mind in the treatment of metastatic breast cancer. In this regards, endocrine therapy (ET) is strongly recommended in hormone receptor (HR) positive patients unless there is visceral crisis even though there is no concrete evidence that it is better than chemotherapy in terms of survival. HER2 positive breast cancer is a subtype of breast cancer that showed the greatest improvement in terms of survival during the last decade due to trastuzumab based therapy. Recently, taxane and HER2 directed doublet including trastuzumab and pertuzumab (THP) is considered as standard of therapy based upon randomized phase 3 clinical trial (CLEOTATRA). HER2 positive breast cancer can be divided into HER2 enriched subgroup (HR-HER2+) and luminal B subgroup (HR+HER2+) in biologic viewpoint because they are distinctly different subgroups in gene expression analysis. Accordingly, we are currently treating biologically different subtypes in a same way, which is CTx and anti-HER2 combination therapy (THP). Luminal HER2+ subgroup has actually been tested with endocrine therapy (ET) and anti-HER2 therapy showed better PFS than ET alone (TAnDEM trial and trial comparing lapatinib plus letrozole versus letrozole alone) [2],[3] confirming existence of cross talk between ER and HER2 pathways in clinical setting. However, the combination regimen between ET and anti-HER2 therapy is not widely used in current practice in ER+HER2+ MBC patients because PFS seemed to be relatively shorter compared with chemotherapy based combination with anti-HER2 therapy even though several guidelines recommend it to be used as an initial treatment unless there is visceral crisis as they recommended ET alone first in ER+HER2- MBC (NCCN 2018). Recently, various CDK4/6 inhibitors including palbociclib, abemaciclib, and ribociclib were approved by FDA based on the clinical trial results demonstrating prolonged PFS over ET alone when it was combined with ET in ER+ advanced breast cancer [4]. In PALOMA 2 biomarker study, it was beneficial regardless of ER and Ki67 expression status. Reflecting quite durable PFS prolongation (10 month in PALOMA2) shown in ER+ disease (luminal A and luminal B subtype except HR+HER2+ patients) with CDK4/6 inhibitor on top of ET, the hypothesis of this trial is whether CDK4/6 inhibitor could prolong survival in luminal HER2 breast cancer as it did in ER+HER2-patients. In preclinical study, palbociclib showed activity in not only ER+ cell lines but also HER2 positive cell lines [5]. Also, in phase Ib trial, a CDK4/6 inhibitor from Lilly, abemaciclib showed acceptable toxicity with endocrine therapy or trastuzumab with response rate of around 20%. Hence, as of today, it could be justified and warranted to conduct a prospective trial of ribocicib+letrozole+trastuzumab in order to take a look at its efficacy and toxicity in HR+HER2 + advanced breast cancer.
This study is a randomized, open-label, phase II study, comparing the efficacy and safety of trastuzumab plus aromatase inhibitors, with or without pyrotinib, in the treatment of HR (hormone receptor)+/HER2 (human epidermal growth factor receptor 2) + MBC and inoperable LABC patients.
To evaluate the efficacy and safety of nab-paclitaxel combined with carboplatin for Chinese patients with triple-negative and HER2-positive breast cancer in the neoadjuvant setting.
This is a phase 2 study evaluating medical treatment before surgery in HER2-amplified early breast cancer patients. Patients receive chemotherapy with HER2-targeted antibodies and are randomised to receive the checkpoint inhibitor atezolizumab or not.
This study was phase IB-II clinical trial that designed to evaluate the efficacy and safety of docetaxel + atezolizumab + Herceptin sc plus pertuzumab(TAHP) plus adjuvant therapy of atezolizumab + trastuzumab + pertuzumab(AHP) after surgery in female patients with HER2-positive early breast cancer. Adjuvant AHP (atezolizumab + Herceptin SC + pertuzumab) will be continued for remaining 1 year. For non-p CR patients, they are going to treat with 4 cycles of AC rather than Taxane only before AHP adjuvant therapy.
In this study, 50 women with either HER2+ or triple negative metastatic breast cancer but no known brain metastases will be recruited at the Sunnybrook Odette Cancer Centre. They will be randomized to undergo either routine MRI screening of their brain every 4 months for 1 year or standard-of-care (MRI only if symptoms of brain metastases develop). Patients will complete questionnaires about quality of life and cancer-related anxiety throughout the study. To determine why some cancers spread to the brain and others do not, blood samples will be collected to analyze the genetic makeup of patients' breast cancers. Finally, a novel MRI imaging technique that detects abnormal metabolism in the brain will be used to help detect brain metastases even earlier than the standard MRI. If results are promising, we will conduct a large multi-centre randomized trial to determine whether screening for brain metastases can help them live longer with improved quality of life.
