BGB-43395 Alone or as Part of Combination Therapies in Participants With Breast Cancer and Other Advanced Solid Tumors
This is a dose escalation and dose expansion study to compare how well BGB-43395, a selective cyclin-dependent kinase 4 (CDK4) inhibitor, works as monotherapy or in combination with fulvestrant, letrozole, or elacestrant in participants with hormone receptor positive (HR+) and human epidermal growth factor 2 negative (HER2-) breast cancer (BC) and other advanced solid tumors. The main purpose of this study is to explore the recommended dosing for BGB-43395.

A Study to Examine the Safety of Different Doses of BG-68501 Given to Participants With Advanced-Stage Tumors
This study is a first-in-human (FIH), Phase 1a/1b study of BG-68501, a cyclin-dependent kinase-2 inhibitor (CDK2i), to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of BG-68501 in participants with advanced, nonresectable, or metastatic solid tumors as monotherapy and in combination with fulvestrant with or without BGB-43395, a selective CDK4 inhibitor, in adults with hormone receptor positive (HR+)/human epidermal growth factor receptor 2 negative (HER2-) breast cancer (BC). The study will also identify a recommended dose for expansion (RDFE) for BG-68501 as monotherapy and in combination for subsequent disease directed studies. The study will be conducted in 2 parts: Part 1 (dose escalation and safety expansion, including evaluation of food effect) and Part 2 (dose expansion).

Impact of Endocrine Therapy, Menstrual Cycle, PAM50, Ki67 on Treatment Decisions in HR+ and HER2- Breast Cancer
PEAK is a prospective, multicenter, non-interventional investigator-initiated trial (IIT) that aims to investigate the influence of the menstrual cycle phase on Ki67 in patients who either receive Tamoxifen, Aromatase inhibitors ± gonadotropin-releasing hormone (GnRH)-Analogues or nothing or no preoperative endocrine treatment as part of the clinical routine. The investigators moreover address the question whether PAM50 assessment in addition to Ki67 dynamics still impacts treatment recommendations.

A Study of Alisertib in Combination With Endocrine Therapy in Patients With HR-positive, HER2-negative Recurrent or Metastatic Breast Cancer
PUMA-ALI-1201 is a randomized, dose optimization, multicenter, Phase 2 study of alisertib administered in combination with endocrine therapy in participants with pathology-confirmed HR-positive/HER2-negative metastatic breast cancer (MBC) following progression on or after at least two prior lines of endocrine therapy in the recurrent or metastatic setting. This study is intended to evaluate the optimal alisertib dose administered in combination with the selected endocrine therapy. The study is also planned to evaluate the efficacy, safety, and pharmacokinetics of alisertib in combination with endocrine and to identify the biomarker-defined subgroup(s) that may benefit most from combined alisertib and endocrine therapy.

Evaluating the Addition of Elacestrant (Oral SERD) to Olaparib (PARP-inhibitor) in Patients With Advanced/Metastatic HR+/HER2- Breast Cancer
Trial design: Phase II, prospective, multi-center, randomized, open label, parallel group study in patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with 2:1 randomization into Arm A (olaparib + elacestrant) or arm B (olaparib). Treatment in either arm will be given until disease progression, unacceptable toxicity, withdrawal of patient´s consent to study participation, or end of study. Trial population: Patients with HR-positive, HER2-negative locally advanced or metastatic breast cancer with gBRCA1/2 mutation, with an indication for standard-of-care PARP inhibitor therapy and planned treatment with olaparib, an ECOG performance status of 0-2 and life expectancy of \> 6 months, with normal bone marrow and kidney functions and no active or newly diagnosed central nervous system (CNS) metastases or symptomatic metastatic visceral disease at risk of life-threatening complications. Interventions: Patients randomized to Arm A will receive 600 mg olaparib daily and 400 mg elacestrant daily, while patients randomized to Arm B will receive 600 mg olaparib daily. Blood tests (hematology, biochemistry) will be performed at the beginning of every cycle, and imaging for tumor assessment (chest and abdominopelvic imaging) as well as QoL assessments will be performed every three months and in case of suspicion of progression/end of study.

Predicting clinicAL outcoMes During First-line CDK4/6 Inhibitors Plus Endocrine Therapy in Patients With Advanced Hormone REceptor-poSitive HER2-negative Breast Cancer: the Retrospective-prospective Multicenter Italian PALMARES-2 Study
PALMARES-2 is a retrospective/prospective, observational, multicenter, population-based study, aiming at providing real-world evidences on HR+/HER2- aBC patients treated with first-line CDK4/6i plus ET. The present study has the objective to collect data coming from different sources, i.e. RWD, medical images and biological samples, from patients treated with CDK4/6i as first-line of therapy for HR+/HER2- aBC. In consideration of the complexity of data collected and different objectives of the study, this master protocol foresees different sub-studies, which encompasses different methodologies for data collection, data extraction and analyses.
