Active clinical trials for "Breast Neoplasms"

The purpose of this study is to find out the effect that CFI-400945 and durvalumab have on breast cancer.

Multicenter, open-label phase II trial assessing the efficacy of DS-8201a monotherapy in patients with metastatic breast cancer.

This is an open-label, three-cohort phase 2 study of KN026 in subjects with advanced breast Cancer.

Primary Objectives: Dose Escalation: To assess the incidence rate of dose-limiting toxicity (DLT) and to determine the maximum tolerated dose (MTD) as well as the recommended dose (RD) of amcenestrant administered as monotherapy and in combination with palbociclib To assess the incidence rate of DLT and determine the RD of everolimus or abemaciclib in combination with the selected amcenestrant dose for the combination therapy Safety Run-In: - To confirm the RD of amcenestrant in combination with alpelisib Dose Expansion: Antitumor activity using objective response rate (ORR) Overall safety profile of amcenestrant administered in combination with palbociclib, alpelisib, everolimus, and abemaciclib Secondary Objectives: Overall safety profile of amcenestrant monotherapy and in combination Pharmacokinetic (PK) profile of amcenestrant administered as monotherapy or in combination and PK profile of palbociclib, alpelisib, everolimus and abemaciclib Antitumor activity using ORR, the clinical benefit rate (CBR) and progression free survival (PFS) Time to first tumor response Residual ER availability with positron emission tomography (PET) scan [(18)F] fluoroestradiol (18F-FES) uptake with increasing doses of amcenestrant Food effect on PK of amcenestrant Potential induction/inhibition effect of amcenestrant on cytochrome P450 (CYP) 3A using 4b-OH cholesterol

Breast cancer is rarely curable after metastasis, and the therapeutic options are limited. Interestingly, the host immune response is strongly predictive for the effect of chemotherapy in subgroups of patients with breast cancer. The aim is to release the brake on the immune response by use of ipilimumab, which blocks CTLA-4 and may deplete regulatory T cells, combined with nivolumab (anti PD1). Importantly, it is possible that non-responders to nivolumab/ipilimumab (nivo/ipi) can be turned responders by use of immunogenic chemotherapy.

This is a Phase 1 study which consists of 2 parts; Dose Escalation part and Expansion part. The dose escalation part is open-label, and evaluates safety, preliminary efficacy and PK of single-agent talazoparib in sequential cohorts of adult patients with advanced solid tumors who are resistant to standard therapy or for whom no standard therapy is available. In the dose escalation part, up to 18 (minimum 3) patients are expected to be enrolled depending on the observed DLTs. The expansion part is designed to assess the efficacy, safety and PK of single-agent talazoparib at RP2D determined in the dose escalation part in adult patients with locally advanced or metastatic breast cancer who have deleterious or suspected deleterious germline BRCA1 or BRCA2 mutations. In the expansion part, a minimum of 17 patients will be enrolled evaluable for the primary endpoint.

This is a multicenter, phase I/II trial of anastrozole, palbociclib, trastuzumab, and pertuzumab is proposed as first-line therapy in metastatic hormone receptor-positive, HER2-positive breast cancer patients. In this phase I/II clinical trial, the researchers aim to establish the safety and efficacy of dual HER2 therapy in combination with palbociclib and anastrozole, which represents a novel and all biologic approach to the treatment of HR+, HER2+ metastatic breast cancer. Additionally, the researchers aim to examine potential biomarkers of response to palbociclib including cyclin D1, cyclin E1 and cyclin E2 expression levels, CDK 2, 4, and 6 levels, phosphorylated retinoblastoma expression and p16 levels. The researchers intend to use RNA sequencing to assess for other predictors of response in an unbiased manner to see if this correlates with inhibition of Ki-67 and phosphorylated retinoblastoma expression as well as evaluate for potential mechanisms of resistance.

Trastuzumab resistance, which is a common therapeutic challenge in HER2 positive metastatic breast cancer, is not fully understood. Pyrotinib is an oral tyrosine kinase inhibitor targeting EGFR, HER-2 and HER-4 receptors. More general inhibition of ErbB family with pyrotinib could provide additional benefit. This study is designed to evaluate the efficacy and safety of pyrotinib in combination with capecitabine in patients with HER2 positive locally advanced or metastatic breast cancer who had early failure on or after trastuzumab treatment.

The purpose of this study is to find out the possible anti-cancer effect of pelareorep in combination with chemotherapy [paclitaxel] and avelumab in treating a type of breast cancer called Hormone Receptor positive (HR+)/Human Epidermal Growth Factor Receptor 2 negative(HER2-) breast cancer, which is either locally advanced or has metastasized (cancer that has spread in your body). The study will investigate if pelareorep in combination with paclitaxel and avelumab is more effective than paclitaxel alone, or pelareorep and paclitaxel. The safety of the combination treatments will also be evaluated.
