Phase 3 Study of RLY-2608 + Fulvestrant vs Capivasertib + Fulvestrant as Treatment for Locally Advanced or Metastatic PIK3CA-mutant HR+/HER2- Breast Cancer

This is a global, multicenter, open-label, randomized Phase 3 study comparing the efficacy and safety of RLY-2608 + fulvestrant to capivasertib + fulvestrant for the treatment of patients with HR+/HER2- ABC with PIK3CA mutation following recurrence or progression on or after treatment with a CDK4/6 inhibitor.

Open-Label Study to Evaluate the Safety, Tolerability, PK, and Efficacy of INX-315 in Patients With Advanced Cancer

Incyclix Bio (Incyclix) is developing INX-315 as an oral, small molecule inhibitor of cyclin dependent kinase 2 (CDK2) for the treatment of human cancers. This first-in-human study is designed to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary antitumor activity of INX-315 in patients with recurrent advanced/metastatic cancer, including hormone receptor positive (HR+)/Human Epidermal Growth Factor Receptor 2 Negative (HER2-) breast cancer who progressed on a prior cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) regimen, and CCNE1-amplified solid tumors who progressed on standard of care treatment. The study will be conducted in 3 parts: Part A (INX-315 monotherapy dose escalation and combination therapy with fulvestrant), Part B (ovarian cancer INX-315 monotherapy dose expansion), and Part C (INX-315 combination therapy with abemaciclib \[a CDK4/6i\] and fulvestrant \[a SERD\] in advanced/metastatic breast cancer; dose escalation and expansion).

I-SPY TRIAL: Neoadjuvant and Personalized Adaptive Novel Agents to Treat Breast Cancer

The purpose of this study is to further advance the ability to practice personalized medicine by learning which new drug agents are most effective with which types of breast cancer tumors and by learning more about which early indicators of response (tumor analysis prior to surgery via magnetic resonance imaging (MRI) images along with tissue and blood samples) are predictors of treatment success.

Adherence to Aromatase Inhibitors ± Abemaciclib Treatment in Patients With Early-stage HER2-negative Breast Cancer

Around 90% of breast cancer patients are diagnosed at an early stage and approximately 70% are hormone receptor-positive and HER2-negative (HR+/HER2-). Despite advancements in adjuvant endocrine therapy, 20-30% of early-stage breast cancer patients relapse within the first decade post-surgery. A recent clinically meaningful therapeutic option for these patients has been cyclin-dependent kinases 4/6 inhibitors (CDK4/6 inhibitors). Abemaciclib and ribociclib were assessed in the adjuvant setting, both showing improvement in invasive disease-free survival (IDFS). Abemaciclib has been approved by the FDA and EMA for HR+/HER2- early breast cancer at high risk of disease recurrence and is the first addition to the Slovenian treatment regimen in routine clinical practice. Poor medication adherence can directly affect the effectiveness of treatment for early HR+/HER2- breast cancer. While adherence data in patients treated with aromatase inhibitors are available, the adherence rate in patients with early HR+/HER2- breast cancer taking abemaciclib remains unclear. In this study, investigators hypothesize that patients receiving abemaciclib in combination with aromatase inhibitors will have lower medication adherence and higher discontinuation rates compared to those receiving aromatase inhibitors alone. It is expected that patients with better quality of life, better cognitive functioning, and a more positive attitude toward their therapy will demonstrate higher medication adherence rates. Adherence may also be influenced by additional factors, such as age and prior treatments.

A Study of the TheraBionic P1 Device in Breast Cancer

The goal of this clinical trial is to learn if adding cancer-specific amplitude-modulated radiofrequency electromagnetic field therapy (TheraBionic P1 device) to the treatment of resectable early-stage breast cancer will affect the pathological response.

A Ph II Study of the TheraBionic P1 Device in Subjects With Hormone Positive Breast Cancer

The goal of this clinical trial is to learn if the TheraBionic P1 device given to patients with advanced or metastatic HR positive, HER2 negative breast cancer who have progressed on standard of care options can affect patients survival. The main questions it aims to answer are: * will the TheraBionic P1 device affect progression free and overall survival in advanced or metastatic HR positive, HER2 negative breast cancer * the long term safety and tolerability of the TheraBionic P1 device * assessment of how the disease responded to the TheraBionic P1 device

Fudan University Shanghai Cancer Center Breast Cancer Precision Platform Series Study- Neoadjuvant Therapy

The purpose of this study is to establish a prospective, single-center platform research based on clinical subtypes to explore precision neoadjuvant therapy in patients with operable breast cancer who met the indications for neoadjuvant chemotherapy and by the update of basic translational research in the center, especially the refinement of typing, the discovery of new targets and the development of novel targeted drugs, verified the effectiveness of new targeted drugs in neoadjuvant therapy.

Establishment of Molecular Profiling for Individual Clinical Routine Treatment Decision in Early Breast Cancer

The present project focuses on how to reduce both over- and under-treatment with adjuvant chemotherapy to a large number of breast cancer patients in Norway. A set of primary tumor prognostic factors can be analysed for potential achievement of this. Furthermore, multi-parameter tests, including detailed molecular analysis of the primary tumors might further improve the selection of patients among the lymph node negative. The study seeks to advance the development of personalised treatment of patients with early breast cancer without lymph node metastasis, by the evaluation of multi-parameter analysis as a means of identifying those patients who are likely to benefit from chemotherapy whilst sparing those who are unlikely to do so from an unnecessary and unpleasant treatment.

Limited Adjuvant Endocrine Therapy for Low Risk Breast Cancer

Phase II trial of 2 years of standard adjuvant endocrine therapy after low risk hormone receptor positive, HER2 negative, node negative breast cancer in women older than 50 at diagnosis. The study hypothesis is that reducing adjuvant endocrine therapy from 5 to 2 years in a population with low risk of breast cancer; as determined by histopathologic criteria and confirmed by low risk genomic analysis using Prosigna®; will be safe and acceptable to this population, and will not compromise the expected excellent breast cancer specific outcomes for this population.

Neoadjuvant Response-guided Treatment of Slowly Proliferating Hormone Receptor Positive Tumors

The purpose of this neoadjuvant trial is to evaluate efficacy and toxicity of the cdk 4/6 inhibitor palbociclib when added to standard endocrine treatment. Initially, patients receive endocrine treatment for 4 weeks. In case of decrease of proliferation (Ki67) patients are then randomized between either continuous endocrine therapy (arm A) or the same treatment with addition of palbociclib (arm B). Patients with no change of proliferation are allocated to endocrine treatment + palbociclib without randomization (arm C). During the 12-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.
