Filter by:Systematic assessment of survival data of patients who have been tested with EndoPredict®; prospective proof that patients with low risk classification by EndoPredict® (EPclin) can safely forgo chemotherapy and be treated with endocrine therapy alone.
The primary purpose of phase 1 portion of this study is to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of H3B-6545 in women with locally advanced or metastatic estrogen receptor (ER)-positive, human epidermal growth factor 2 (HER2)-negative breast cancer. The primary purpose of phase 2 portion of this study is to estimate the efficacy of H3B-6545 in terms of best overall response rate, duration of response (DoR), clinical benefit rate (CBR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) in all participants with ER-positive, HER2-negative breast cancer and in those with and without ER alpha mutation (including a clonal estrogen receptor 1 gene [ESR1] Y537S mutation).
This is an open-label, multicentric, international, phase II trial testing aromatase inhibitors in combination with durvalumab in patients with CD8+ T cell infiltration (>10% CD8+ T cells in the tumor). The trial includes two sequences: The first part of the treatment will consist in 4-6 weeks treatment with immune-attractants; in the second part, CD8+ patients will receive 6 months of durvalumab combined with exemestane.
The purpose of this neoadjuvant trial is to evaluate efficacy and toxicity of chemotherapy using weekly paclitaxel (arm A) versus the combination of the cdk 4/6 inhibitor palbociclib and standard endocrine treatment (arm B). After 12 weeks treatment is switched crossover. During the 24-weekly treatment period, clinical and radiological evaluations are performed repeatedly. Switch between the treatment arms A and B is allowed in case of lack of response or due to toxicity. A translational subprotocol is a mandatory part of the study protocol, except for use of PET-CT evaluations. Postoperatively, patients receive three 3-weekly courses of chemotherapy with a combination of epirubicin and cyclophosphamide.
The aim of this study is to increase, by DHA-induced chemosensitization, the activity of anticancer chemotherapy in patients with a metastatic advanced breast cancer, by a nutritional approach with marin-derived PolyUnsaturated Fatty Acids (PUFA).
This is a Phase 2, multicenter, single-arm, feasibility study evaluating eribulin in combination with capecitabine as an adjuvant chemotherapy regimen in approximately 65 subjects with early-stage (I-II), human epidermal growth factor receptor 2 (HER2)- normal, estrogen receptor (ER)-positive breast cancer.
Fulvestrant is an ER antagonist with no agonist effects, which binds, blocks and degrades the ER. Fulvestrant is comparable to third-generation aromatase inhibitors in terms of efficacy and tolerability for patients who have progressed on prior tamoxifen therapy and past studies have found all three-third-generation AIs to be at least as good as tamoxifen in first-line metastatic therapy in postmenopausal women. Fulvestrant has been studied little in premenopausal women despite of its attractive mechanism of actions. The clinical effectiveness of fulvestrant as a treatment for advanced breast cancer has previously been demonstrated at the standard dose (AD; 250 mg/mo) in several phase III clinical trials in postmenopausal women. However, there is evidence to suggest that doses of fulvestrant higher than 250 mg may have greater pharmacodynamic activity against the ER pathway. Moreover, dose-dependent clinical activity has been observed for fulvestrant. The activity of a fulvestrant high-dose (HD; 500 mg/mo) regimen has been investigated in two recent studies. A pilot Japanese study showed fulvestrant HD to have clinical activity in the treatment of advanced or recurrent breast cancer, to be well tolerated, and to result in plasma levels approximately double those seen with fulvestrant low-dose. Subsequently, a neoadjuvant study comparing fulvestrant low-dose and high-dose reported that significantly greater Ki67 and ER downregulation was achieved with the high-dose compared with the low-dose regimen and that both doses were well tolerated. A recent randomized trial also showed superior outcome of high-dose fulvestrant than AI. Based on this rationale, we introduced high-dose fulvestrant with LHRH agonist as a randomized trial comparing with AI plus LHRH agonist and LHRH alone in premenopausal metastatic breast cancer patients who failed to tamoxifen treatment.
