Trastuzumab Deruxtecan Alone or in Combination With Anastrozole for the Treatment of Early Stage HER2 Low, Hormone Receptor Positive Breast Cancer

NCT04553770ClinicalTrials.gov ↗

This phase II trial investigates how well trastuzumab deruxtecan works alone or in combination with anastrozole in treating patients with HER2 low, hormone receptor positive breast cancer. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug called deruxtecan. Trastuzumab attaches to HER2 expressed at low levels on cancer cells in a targeted way and delivers deruxtecan to kill them. Anastrozole works by decreasing estrogen production and suppressing the growth of tumors that need estrogen to grow. This study is evaluating how effective trastuzumab deruxtecan is at treating hormone receptor positive cancer cells that have low levels of HER2 expressed on them when given alone or in combination with anastrozole.

Non-interventional Study to Assess the Effectiveness and Safety of Ribociclib in the Adjuvant Therapy of Hormone Receptor Positive (HR+) HER2-negative Stage II and III Breast Cancer in Real Clinical Practice in Russia

NCT06930859ClinicalTrials.gov ↗

This prospective, observational, multicenter study aims at evaluating the efficacy of adjuvant ribociclib in combination with hormone therapy (aromatase inhibitor ± GnRH aginost) in various subgroups of patients with HR+HER2- stage II-III breast cancer in real clinical practice in Russia. Subgroup division will be based on the tumor grade, lymph node involvement, and the response to test hormone therapy. The study will consist of two cohorts: a prospective one with patients receiving adjuvant therapy with ribociclib combined with Aromatase inhibitors (AI), and a retrospective one with patients receiving adjuvant therapy with AI alone. Thus, both primary data collection and secondary use of data will be organized.

NeoTAILOR: ABiomarker-directed Approach to Guide Neoadjuvant Therapy for Patients With Stage II/III ER-positive, HER2-negative Breast Cancer

NCT05837455ClinicalTrials.gov ↗

This study aims to utilize a novel biomarker-driven approach to guide neoadjuvant treatment selection. It is the hypothesis that this will improve clinical response for postmenopausal women with clinical stage II/III ER-positive, HER2-negative breast cancer and identify those who may not require neoadjuvant chemotherapy, with a primary focus on outcomes in Black patients.

First-in-Human Study of Tersolisib (STX-478) as Monotherapy and in Combination With Other Antineoplastic Agents in Participants With Advanced Solid Tumors

NCT05768139ClinicalTrials.gov ↗

Study STX-478-101 (LY4064809) is a multipart, open-label, phase 1/2 study evaluating the safety, tolerability, pharmacokinetics (PK), and preliminary antitumor activity of STX-478 (LY4064809) in participants with advanced solid tumors with P13Ka mutations. Part 1 will evaluate STX-478 as monotherapy in participants with advanced solid tumors. Part 2 will evaluate STX-478 therapy as combination therapy with fulvestrant in participants with hormone receptor positive (HR+) breast cancer. Part 3 will evaluate STX-478 as combination therapy with endocrine therapy (aromatase inhibitors, fulvestrant, tamoxifen, or imlunestrant) and a CDK4/6 Inhibitor (either Ribociclib, Palbociclib or Abemaciclib) in participants with HR+ breast cancer. Each study part will include a 28-day screening period, followed by treatment with STX-478 monotherapy or combination therapy.

A Trial of Early Detection of Molecular Relapse With Circulating Tumour DNA Tracking and Treatment With Palbociclib Plus Fulvestrant Versus Standard Endocrine Therapy in Patients With ER Positive HER2 Negative Breast Cancer

NCT04985266ClinicalTrials.gov ↗

Detection of molecular relapse with circulating tumour DNA analysis can identify which patients with ER positive breast cancer are relapsing on adjuvant endocrine therapy. This trial will aim to demonstrate that palbociclib and fulvestrant, can defer or prevent relapse in patients with ctDNA detected molecular relapse. The TRAK-ER trial will have two phases, a ctDNA surveillance phase and a randomised therapy trial in patients with positive ctDNA. The TRAK-ER trial will establish a ctDNA screening programme for patients with ER positive breast cancer receiving adjuvant endocrine therapy with at least a further three years of standard adjuvant endocrine therapy planned. Patients recruited into the TRAK-ER study will have high-risk clinical features to identify patients at higher risk of future relapse. ctDNA assays will be used to identify which people are at very high risk of relapse (i.e. those with a positive ctDNA result), and randomise this high risk population between standard endocrine therapy versus palbociclib plus fulvestrant for up to two years.

Testing Whether Hormone Therapy With Ribociclib is as Effective as Chemotherapy Followed by Hormone Therapy With Ribociclib for the Treatment of High Anatomic Stage Breast Cancer With Low Recurrence Risk, The RxFINE-Low Trial

NCT07391774ClinicalTrials.gov ↗

This phase III trial compares standard of care hormone therapy plus ribociclib to chemotherapy followed by hormone therapy plus ribociclib for the treatment of patients with high anatomic stage breast cancer with low risk of the cancer returning (low risk recurrence). Ribociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hormone therapy, with letrozole, anastrozole or exemestane, lowers the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. Chemotherapy drugs work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Hormone therapy plus ribociclib may work as well as chemotherapy followed by hormone therapy plus ribociclib for the treatment of high anatomic stage breast cancer with low recurrence risk.

NCT05524584ClinicalTrials.gov ↗

This is a phase 2, open-label, singled-arm clinical trial determining efficacy of combination therapy with anastrozole, fulvestrant and abemaciclib in subjects with breast cancer. These are subjects who are newly diagnosed advanced or metastatic hormone receptor positive breast cancer or subjects who have progressed following treatment free interval of more than 12 months following adjuvant or neoadjuvant treatment.

Functional Imaging in Prediction of Response to Abemaciclib for Advanced Hormone Receptor-Positive, HER2-Negative Breast Cancer

NCT06179303ClinicalTrials.gov ↗

This phase II trial tests the accuracy of functional imaging (FFNP)-positron emission tomography (PET)/computed tomography (CT) to predict response to abemaciclib plus endocrine therapy. Abemaciclib is a drug used to treat certain types of hormone receptor positive (HR+), HER2 negative breast cancer. Abemaciclib blocks certain proteins, which may help keep tumor cells from growing. Endocrine therapy adds, blocks, or removes hormones that can cause cancer to grow. FFNP PET imaging is a form of x-ray that uses FFNP as an imaging agent that may provide more precise information about the location of tumors that "light up" with FFNP than a PET scan alone can provide.

A Study of Tersolisib (LY4064809/STX-478) With Other Anti-Cancer Treatments in Participants With Advanced Breast Cancer With a Genetic Change (PIK3CA)

NCT07174336ClinicalTrials.gov ↗

The purpose of the study is to assess the efficacy and safety of the addition of Tersolisib (LY4064809/STX-478) to other anti-cancer drugs as first treatment for advanced hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer. Participants can remain in the study as long as the drug is helping the cancer without unbearable side effects.
