PROVIDENCE - Prospective Non-interventional Study (NIS) to Examine Patient-reported Outcomes and Real-world Clinical Data in Patients With HER2-positive or HER2-low Unresectable or Metastatic Breast Cancer Treated With Trastuzumab Deruxtecan

Eligible participants will be those patients with documented HER2-positive unresectable or metastatic BC receiving T-DXd treatment or patients with documented HER2-low unresectable or metastatic BC receiving T DXd treatment in line with the applicable summary of product characteristics (SmPC) within routine clinical practice. All diagnostic and treatment procedures including visit frequency are at the discretion of the treating physician and not defined by the protocol. T-DXd treatment is considered as a selection criteria. Patients will be informed about use of digital healthcare application (DiGA). Approximately 800 eligible participants will be enrolled which includes 400 patients in the HER2-positive cohort and 400 patients in the HER2-low cohort.

Comprehensive Analysis of Spatial, Temporal and Molecular Patterns of Ribociclib Efficacy and Resistance in Advanced Breast Cancer Patients

This is a prospective, multicenter, phase IV, one-arm, open-label clinical trial investigating patients treated with ribociclib and standard of care endocrine therapy for hormone receptor positive (HR+) / human epidermal growth factor receptor negative (HER2-) advanced breast cancer in the first therapy line. Patients eligible for this trial will receive on-label ribociclib according to Summary of Product Characteristics (SmPC) and as well as the specified inclusion/exclusion criteria. The survival rates for progression-free survival (PFS) and overall survival (OS) at month 12 are the co-primary objectives. Quality of life and toxicity are secondary objectives. Additionally, there is a comprehensive biomarker discovery and validation program included into the study. A total of 1000 patients are planned to be enrolled into this trial in 75 trial sites in Germany. Biomarkers will be evaluated before, during and after treatment or at progression. A comprehensive biospecimens sampling will be done to enable translational research projects and evaluation of potential biomarkers within circulation tumor desoxyribonucleic acid (ctDNA), circulating tumor ribonucleic acid (ctRNA), formaldehyde-fixed paraffin-embedded tissue (FFPE) tissue, Serum, Plasma and circulating immune cells

International PFO Consortium

Background The prevalence of patent foramen ovale (PFO) is about 25% in the general population and approximately 40% in patients who have ischemic stroke of unknown cause (cryptogenic stroke). Given the large number of asymptomatic patients, no primary prevention is currently recommended. On the contrary, secondary prevention is very important. Prospective studies have shown that antithrombotic treatment (ATT) with aspirin or warfarin appears to negate the risk of recurrent stroke associated with a PFO. Patients with spontaneous or large right-to-left shunts (RLS), those with a coinciding atrial septal aneurysm (ASA) or multiple ischemic events prior to the PFO diagnosis may still be at increased risk of stroke recurrence despite ATT. Percutaneous device closure (PDC) is a challenging alternative to ATT. Several studies reported 0% to 3.4% annual recurrence rates of stroke or TIA in patients treated by PDC. To date, there is no data from randomized controlled trials (RCT) comparing the risk of stroke recurrence after PDC with that under ATT only. The results from ongoing RCTs are not to be awaited in the near future, mainly due to low enrolment and event rates. Even if RCTs are completed successfully, statistical differences may remain undetected with the planned sample sizes. Alternative data-gathering strategies such as multicenter registries are needed to overcome the low recruitment rates. Objective 1) To compare the risk of recurrent stroke and TIA in patients aged ≤ 55 years with PFO and otherwise unexplained stroke who undergo PDC or receive ATT only; 2) To assess the etiological role of PFO for stroke/TIA in patients aged > 55 years; 3) To assess the risk of recurrent stroke/TIA in "high-risk" PFO patients (i.e. those with spontaneous (at rest) or large RLS, coinciding ASA, or multiple previous cerebrovascular events). Methods Multicenter prospective non-randomized study with scheduled 3-years follow-up of patients with PFO and ischemic stroke or TIA. Participating centers: Swiss University Hospitals of Basel, Bern, Geneva, Lausanne and Zurich, the Cantonal Hospital of Aarau, the Triemli Hospital, the Alfried-Krupp Krankenhaus of Essen, the University Hospital of Essen, the Klinikum Worms gGmbH, Tufts Medical Center, Baystate Medical Center, the East Medical Center Tyler, and the University Hospital of Leuven.

Evaluation of HU-resistance in Adult Patients With Polycythemia Vera Who Meet PV-AIM Predictors

This is an open-label, prospective, single arm, Phase IV interventional study to evaluate the HU-resistance/intolerance in PV patients who meet predictive parameters identified in the machine learning project PV-AIM. The study consists of three periods: screening period, treatment period (observation for HU-resistance/intolerance) and follow-up (FU) period. Eligible participants will enter the treatment period (observation for HU-resistance/intolerance) and start receiving the de novo HU treatment. The maximum treatment duration for each participant in the study will be up to 15 months. This study will be conducted in a total of 300 adult PV patients and approximately at 30 sites in Germany.
