Filter by:Despite different clinical characteristics including the response to treatment and the patterns of metastatic relapse, invasive lobular breast carcinoma (ILBC) is treated like invasive ductal breast carcinoma (IDBC) carcinoma both in the clinics and in clinical trials. A large majority of ILBC are ER+/HER2- and almost 90% have loss of E-cadherin (CDH1) expression. A non-clinical study of CDH1 synthetic lethality interactions has identified ROS1 as a potential target. In vivo, ROS1 inhibitors produced profound antitumor effects in multiple models of E-cadherin-defective breast cancer, providing the preclinical rationale for assessing ROS1 inhibitors in this setting. Endocrine therapy being the mainstay of therapy for ER+/HER2- ILBC and the pre-operative setting offering a platform for rapid drug evaluation and biomarker research, the ROSALINE phase 2 study will evaluate the efficacy of Entrectinib (a potent inhibitor of ROS1 among other targets) in combination with letrozole (+ goserelin in premenopausal women) in the early setting of ILBC (stages 1 to 3). The neoadjuvant therapy will last 4 months and post-operative therapy will follow local practice. Biomarker research will include RNA sequencing of initial biopsies and surgical specimens, as well as liquid biopsies.
This clinical study is aiming to determine the safest doses and schedule for the combination of two drugs named palbociclib and avelumab. The study will also be investigating how effective the combination is for a subgroup of breast cancer patients whose cancer expresses the androgen receptor (AR) but not the oestrogen (hormone) or HER2 receptors. Palbociclib is a drug used in routine care for hormone-receptor (HR) positive and HER2 negative advanced breast cancer, the most common subtype of breast cancer. It is possible that the combination of palbociclib and avelumab will be a more effective cancer treatment than each drug separately, but this is unknown and this study is needed to establish the best dosage and schedule of each drug as well as how effective the combination is.
The objectives of this study is to perform CYP2D6 genotyping and metabolite concentrations analysis on ER+ breast cancer patients who are taking tamoxifen and give dose recommendations based on the CYP2D6 genotypes and endoxifen levels.
This is a dose escalation, MTD expansion (Phase 1b) and cohort expansions (Phase 2) study to assess the safety and tolerability of a combination of NAP with durvalumab in subjects with selected advanced or metastatic solid tumors.
The goal of this clinical study is to determine the safety, pharmacokinetics, pharmacodynamics and efficacy and activity of seviteronel, a lyase-selective inhibitor of CYP17, in patients with advanced breast cancer.
The purpose of this study is to assess the safety and effectiveness of AZD4547 in combination with fulvestrant vs. fulvestrant alone in ER+ breast cancer patients with FGFR1 polysomy (FISH4/5) or gene amplification (FISH 6)
The addition of entinostat to an AI will result in a maximal abrogation of estrogen receptor-α mediated activity and inhibit mechanisms of resistance to the aromatase inhibitor. It is hypothesized that entinostat with continued AI will increase the estimated AI clinical benefit rate (CBR) from 5% to 25% with an acceptable safety profile.
The purpose of this study is to evaluate the safety and efficacy of entinostat in combination with exemestane in the treatment of advanced breast cancer.
