Filter by:This study is being done to see if tucatinib with ado-trastuzumab emtansine (T-DM1) works better than T-DM1 alone to help patients who have a specific type of breast cancer called HER2 positive breast carcinoma. The breast cancer in this study is either metastatic (spread into other parts of the body) or cannot be removed completely with surgery. Patients in this study will be randomly assigned to get either tucatinib or placebo (a pill with no medicine). This is a blinded study, so neither patients nor their doctors will know whether a patient gets tucatinib or placebo. All patients in the study will get T-DM1, a drug that is often used to treat this cancer. Each treatment cycle lasts 21 days. Patients will swallow tucatinib pills or placebo pills two times every day. Patients will get T-DM1 injections from the study site staff on the first day of every cycle.
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 .
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.
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.
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.
This is a one stage phase II study with a single arm design. It will be conducted in HER-2 positive breast cancer patients in Nigeria who are chemotherapy/hormonal treatment naive.
Phase II Pilot Study of Trastuzumab Biosimilar (Herzuma®) plus Gedatolisib in Patients with HER-2 Positive Metastatic Breast Cancer Who Progressed after 2 or more HER-2 directed Chemotherapy
This phase I trial studies the side effects and best dose of HER2-CAR T cells in treating patients with cancer that has spread to the brain or leptomeninges and has come back (recurrent). HER2-CAR T cells delivered into the ventricles of the brain may recognize and kill tumor cells.
A large multi- center phase II/III study with 68Ga-ABY-025 PET and biopsies in patients with advanced HER2-positive breast cancer, where the primary endpoint of the study is to find out the correlation between the HER2 expression measured by 68Ga-ABY-025 PET and standard histopathology from relevant tumor biopsies.
First preclinical data suggest that pegfilgrastim could constitute a potent adjuvant for immunotherapy with mAb possessing ADCC/ADCP properties as trastuzumab. Combined treatment of pegfilgrastim and trastuzumab should translate into an increased rate of pathological clinical response. Therefore the investigators' proposal is to evaluate the clinical and biological impact of pegfilgrastim in combination with trastuzumab + paclitaxel in HER2-positive early stage breast cancer patients. Breastimmune02 is a multicenter, randomized, open-label, Phase II trial. Operable HER2+ breast cancer patients previously treated with 4 cycles of standard adriamycine/cyclophosphamide (AC) chemotherapy will be randomized (1:1) to receive in the neoadjuvant setting:Arm A: weekly paclitaxel + trastuzumab (every 3 weeks, Q3W) + pegfilgrastim (Q3W) versus Arm B: weekly paclitaxel + trastuzumab (Q3W).Stratification criteria will be: cN0 versus cN1.
