Background: Alpelisib, a PI3Kα-selective inhibitor and degrader, plus fulvestrant showed efficacy in hormone receptor-positive, HER2-negative, PIK3CA-mutated advanced breast cancer in SOLAR-1; limited data are available in the post-cyclin-dependent kinase 4/6 inhibitor setting. BYLieve aimed to assess alpelisib plus endocrine therapy in this setting in three cohorts defined by immediate previous treatment; here, we report results from cohort A.

Methods: This ongoing, phase 2, multicentre, open-label, non-comparative study enrolled patients with hormone receptor-positive, HER2-negative, advanced breast cancer with tumour PIK3CA mutation, following progression on or after previous therapy, including CDK4/6 inhibitors, from 114 study locations (cancer centres, medical centres, university hospitals, and hospitals) in 18 countries worldwide.

Article Synopsis
  • In 2020, Novartis and the FDA began a 4-year collaboration to explore radio-genomics for predicting factors in HR+/HER- metastatic breast cancer.
  • The partnership focuses on harnessing advanced analytics and AI to improve future scientific projects.
  • The tutorial offers guidelines for conducting multi-omics research, emphasizing communication, data practices, and outlining a four-step process: plan, design, develop, and disseminate.

Article Synopsis
  • - The MONALEESA-2, -3, -7 trials found that adding ribociclib to endocrine therapy significantly improved progression-free survival and overall survival in patients with hormone receptor-positive, HER2-negative advanced breast cancer.
  • - A study of tumor samples identified four intrinsic subtypes: luminal A (54.5%), luminal B (28.0%), HER2-enriched (14.6%), and basal-like (2.8%), with luminal A showing the best overall survival outcomes, while basal-like had the worst.
  • - The analysis confirmed that patients with luminal and HER2E subtypes benefit from ribociclib, whereas those with basal-like subtype did not show significant benefits from the

Background: There is increasing interest in the use of liquid biopsies, but data on longitudinal analyses of circulating tumor DNA (ctDNA) remain relatively limited. Here, we report a longitudinal ctDNA analysis of MONALEESASIA, a phase Ib trial evaluating the efficacy and safety of ribociclib plus endocrine therapy (ET) in Asian patients with hormone receptor-positive, human epidermal growth factor receptor-2-negative advanced breast cancer.

Methods: MONALEESASIA enrolled premenopausal and postmenopausal Japanese and postmenopausal non-Japanese Asian patients.

Ribociclib in combination with endocrine therapy (ET) is a globally approved treatment option for patients with hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) and has demonstrated significantly improved overall survival (OS) in 3 phase 3 clinical trials. To justify the dose regimen and dose modification scheme for patients with ABC, the pharmacokinetic (PK), safety, and efficacy data of ribociclib were analyzed. The data of several phase 1-3 clinical studies were pooled and analyzed to characterize the relationship between exposure (dose or PK) and efficacy (progression-free survival (PFS), time to response, and OS) or safety (neutropenia and QT interval prolongation).

Article Synopsis
  • Ribociclib has been shown to improve overall survival for patients with HR+/HER2- advanced breast cancer, and the NATALEE trial aims to evaluate its safety and effectiveness when combined with endocrine therapy for early nonmetastatic cases.* -
  • This Phase III trial involves a randomized, multicenter design, enrolling men and women with specific stages of breast cancer, and compares ribociclib with endocrine therapy alone, focusing on invasive disease-free survival as the main outcome.* -
  • The trial extends ribociclib treatment to 36 months to enhance effectiveness and uses a lower dosage to improve tolerability, including a diverse patient population for more comprehensive results on adjuvant therapy.*

Background: This pooled analysis of MONALEESA trials evaluated the safety of ribociclib plus endocrine therapy (RIB + ET) with a focus on dose reductions in first-line patients.

Methods: In the dose reduction analysis, data were pooled from MONALEESA-2 (all patients), MONALEESA-3 (patients receiving treatment as first-line ET) and MONALEESA-7 (patients receiving combination therapy with an NSAI as initial ET). Efficacy was analysed by ribociclib relative dose intensity (DI).

Background: The BYLieve trial (NCT03056755) confirmed efficacy and safety of alpelisib with fulvestrant for hormone receptor-positive (HR+), human epidermal growth factor receptor-2-negative (HER2-), PIK3CA-mutated advanced breast cancer (ABC), after cyclin-dependent kinase 4/6 inhibitor (CDK4/6i) with an aromatase inhibitor (AI) as immediate prior therapy. Further analyses were performed to compare efficacy from BYLieve with effectiveness of standard treatment in the real-world setting.

Materials And Methods: Patients who progressed on a CDK4/6i plus AI and were treated with alpelisib with fulvestrant in BYLieve were matched with a real-world patient cohort who received standard-of-care from a deidentified clinico-genomics database (CGDB).

Purpose: To evaluate the effect of lapatinib on the QTc interval and ECG parameters in patients with advanced solid tumors.

Methods: This was a multicenter, placebo-controlled study in subjects with advanced solid tumors. Subjects were administered two doses of matching placebo on day 1, 12 h apart and one dose in the morning on day 2.

Objectives: A multicenter, noninterventional, observational study was conducted in the Latin American countries including Argentina, Brazil, Colombia, Mexico, and Venezuela to assess the prevalence of liver and cardiac iron overload using magnetic resonance imaging (MRI) in patients with chronic anemias except thalassemia.

Methods: Patients aged >10 years with transfusion-dependent anemias, except thalassemia, either with <20 units of red blood cell (RBC) transfusions with serum ferritin (SF) levels >2000 ng/mL or with ≥20 units of RBC transfusions regardless of SF level in their lifetime, were enrolled. Iron overload was assessed using MRI.
