Researchers are evaluating the real-world effectiveness, safety, and tolerability of ribociclib combined with an aromatase inhibitor, with or without luteinizing hormone-releasing hormone (LHRH) therapy, for adjuvant treatment in patients with hormone receptor-positive, HER2-negative early breast cancer at high risk of recurrence. The study also compares data from patients treated with abemaciclib plus endocrine therapy with or without LHRH, and those receiving endocrine monotherapy with or without LHRH. This observational study aims to understand treatment decisions and clinical use of ribociclib after its approval, collecting socio-economic data, quality of life, and patient compliance information. Participants receive treatment based on their physician's clinical judgment without study-assigned interventions. The treatments observed include ribociclib with an aromatase inhibitor LHRH, abemaciclib with endocrine therapy LHRH, or endocrine monotherapy LHRH. The study is conducted in various breast cancer centers and gynecological practices in Germany and Austria to represent local healthcare settings. Participants undergo assessments to monitor treatment effectiveness, safety, quality of life, and adherence to therapy over time. Data collected include clinical outcomes, adverse events, socio-economic status, and patient-reported compliance. The primary outcome measured is invasive disease-free survival over 36 months. This information will help inform clinical decision-making and improve outcomes for patients with early breast cancer in routine practice.

Researchers are studying metastatic colorectal carcinoma (mCRC) patients whose tumors have a BRAFV600E mutation, which is known to have a poorer outlook compared to non-mutated cases. Standard treatments after the first therapy have shown limited success, with low response rates and short survival times. This study aims to understand how the combination of encorafenib and cetuximab works in real-world settings, focusing on effectiveness, quality of life, safety, and tolerability in German, Austrian, and Swiss patients who have already received prior therapies. Participants will receive encorafenib combined with cetuximab, treatments that target specific cancer mutations. This study is observational and non-interventional, meaning it records how patients respond to these drugs in routine care without altering their treatment. The study allows initial retrospective data collection and will follow patients longitudinally to gather comprehensive information about their experiences with the therapy. During the study, patients will be monitored for overall survival twelve months after starting treatment. Researchers will assess how well the treatment controls the cancer, side effects experienced, and patients' quality of life. Data will be collected from medical records and patient reports in regular clinical care, providing insights into the real-life use and impact of encorafenib and cetuximab for this patient group.

Researchers are investigating the use of ribociclib combined with standard endocrine therapy as a first-line treatment for women with advanced hormone receptor positive (HR+) and human epidermal growth factor receptor negative (HER2-) breast cancer. This phase IV, open-label, single-arm study aims to evaluate the progression-free survival (PFS) and overall survival (OS) rates at 12 months, along with quality of life, treatment toxicity, and comprehensive biomarker analysis to understand patterns of treatment efficacy and resistance. Participants will receive ribociclib orally at a dose of 600 mg daily for 21 consecutive days followed by 7 days off, in 28-day cycles, combined with standard endocrine therapy according to current guidelines and local practice. The study includes extensive biomarker sampling before, during, and after treatment or at disease progression, including blood, tissue, and immune cell analyses to support translational research. During the trial, patients will attend scheduled visits for monitoring and assessments including survival status, safety evaluations, and quality of life questionnaires. Biomarker samples such as circulating tumor DNA and RNA, serum, plasma, and tumor tissue will be collected to evaluate biological changes. The trial plans to enroll 1000 female patients across 75 sites in Germany, with comprehensive follow-up to track treatment outcomes and long-term safety.

Researchers are investigating the use of elacestrant compared to standard endocrine therapy in patients with estrogen receptor-positive (ER+) and human epidermal growth factor receptor 2-negative (HER2-) breast cancer who have a relapse detected by circulating tumor DNA (ctDNA). This international, multi-center, randomized, open-label phase III trial aims to determine if elacestrant offers a benefit over current endocrine treatments in this group of patients without distant metastases. The study includes a lengthy ctDNA screening phase to identify eligible participants and monitor their disease status over time. The study begins with a ctDNA screening phase, where patients receive standard adjuvant endocrine therapy such as tamoxifen, letrozole, anastrozole, or exemestane, and have blood collected every six months for ctDNA testing until about 5.7 years after enrollment ends. Those who test positive for ctDNA and show no distant metastasis on imaging will be randomized within four weeks to continue their current endocrine therapy or switch to elacestrant taken orally at 400 mg daily. Treatment duration varies based on prior endocrine therapy exposure, ranging from two to seven years. After treatment, further care is at the physician's discretion. Participants will have frequent follow-up visits with ctDNA testing at weeks 4 and 16 post-randomization and every 16 weeks thereafter for up to three years. Imaging studies including mammograms, bone scans, and CT scans will be conducted regularly to monitor for distant metastases or new cancers. The main outcome measured is distant metastasis-free survival, assessed up to 6.25 years following the first patient enrollment. The study ends when all patients complete their visits or discontinue for reasons such as withdrawal, loss to follow-up, or death, and data is fully analyzed and finalized.

Researchers are collecting data on patients diagnosed with BCR-ABL 1-negative myeloid neoplasms, a type of blood cancer classified by the WHO in 2008 and 2016. The study aims to register many patients at participating centers to better understand the disease by analyzing biological features and clinical outcomes, including quality of life. The research also focuses on identifying prognostic and predictive markers by correlating disease characteristics with patient results. Participants will be part of a registry study where samples such as bone marrow aspirates, blood, plasma, buccal swabs, and occasionally skin biopsies are collected and stored. Morphologic and genetic analyses will be performed on these samples. There is no intervention treatment; instead, the study gathers extensive clinical and biological data over time to support research. During the study, patients' clinical characteristics, quality of life, and outcome data will be assessed using specific questionnaires and defined clinical variables. Researchers will monitor treatment decisions, response to therapy, survival rates, and progression-free survival for up to 25 years. This long-term follow-up allows comprehensive tracking of the disease course and patient well-being.

Immune thrombocytopenia (ITP) is a rare blood disorder where the immune system causes a shortage of platelets, leading to increased bleeding risk. New treatment options have emerged recently, but clinical studies often focus on specific patient groups. This research collects real-world data from a broad range of ITP patients to better understand the diagnosis, treatment, and outcomes in everyday care. The study also aims to improve personalized therapy and patient results by gathering detailed clinical and biospecimen information. The study involves creating a national registry where clinical data and biospecimens are collected from patients diagnosed with primary or secondary ITP. Data are gathered prospectively at defined points during the disease course, and patients can also be included retrospectively within 12 months of diagnosis if ongoing documentation is available. This includes information about disease factors, treatment types, complications, quality of life, fatigue, and survival over 5 years. Participants will provide written consent and undergo clinical assessments at enrollment and follow-up visits. Researchers will collect epidemiological data such as disease incidence, age and sex distribution, causes, treatment types, and remission status over 5 years. The registry also includes biospecimen collection to support high-quality, standardized research. This ongoing monitoring will help improve knowledge of ITP and support better patient care.

Researchers are evaluating the safety and effectiveness of GLSI-100 immunotherapy in people with HER2/neu positive breast cancer who are at high risk of the cancer coming back. This Phase 3 study focuses on individuals who have completed both neoadjuvant and postoperative adjuvant standard treatments, including trastuzumab-based therapy. The study includes participants who are HLA-A*02 positive, with an additional open-label arm for non-HLA-A*02 positive subjects, aiming to understand how this immunotherapy may help prevent invasive breast cancer recurrence. Participants receive treatment through a series of injections: six intradermal injections as the Primary Immunization Series over the first six months, followed by five booster injections given every six months. One group receives the investigational GLSI-100, which contains GP2 and GM-CSF, while a control group receives placebo injections containing normal saline. The open-label arm explores the treatment in non-HLA-A*02 positive subjects. Throughout the study, participants are monitored for invasive breast cancer-free survival over a median follow-up of four years, with interim analyses planned. Assessments include clinical evaluations to confirm no residual or persistent breast cancer, organ function tests, and pregnancy tests. Safety and efficacy data are collected to understand the treatment's impact, with participants followed closely during and after the treatment period to track outcomes and side effects.

The trial investigates the effectiveness, safety, and patients' quality of life when using additive chemotherapy after surgery or ablation in patients with metastatic colorectal cancer. This phase III, open-label, randomized, controlled, multicenter study compares two groups: one receiving chemotherapy and the other undergoing active follow-up without additional treatment. All patients have had their metastatic lesions definitively treated before joining the trial. Participants in the chemotherapy group receive up to six months of treatment with either mFOLFOXIRI or mFOLFOX-6, with up to 12 cycles administered every two weeks. The other group undergoes active surveillance without further chemotherapy. The study includes regular tumor biopsies at screening and upon relapse if possible, aiming to study tumor and blood markers. Imaging scans such as CT or MRI of the chest and abdomen are performed every three months during the first two years, then every six months thereafter, with follow-up continuing for up to five years. Throughout the study, patients are monitored every three months with radiologic assessments, blood tests, and quality of life questionnaires. Researchers aim to detect any cancer relapse through imaging and blood markers and evaluate progression-free survival over 24 months. Safety and clinical status are regularly assessed, and structured follow-up is maintained for both groups up to 60 months after randomization.

Researchers are studying both early and advanced/metastatic breast cancer to improve therapy decisions and healthcare quality. Metastatic breast cancer patients often have the poorest prognosis, and there is a need to better understand tumor characteristics to guide targeted therapies. This study aims to establish methods for analyzing molecular features of tumors and metastases using blood samples, as tumor biopsies can be invasive and are not routinely performed despite recommendations. Participants will have blood samples taken during routine blood draws to analyze tumor expression, mutations, gene copy number changes, and other molecular markers. The study focuses on creating a comprehensive infrastructure for molecular assessment in breast cancer patients at different stages. The research also explores healthcare outcomes and economics to enhance patient integration and awareness. Participants will be monitored to discover biomarkers that predict progression-free survival in metastatic breast cancer and assess disease-free survival in early breast cancer over up to 60 months. The study involves routine clinical assessments and blood collections, with data collected on tumor characteristics and patient health outcomes. Overall participation spans long-term follow-up to evaluate progression and survival measures.

Researchers are studying pre- and perimenopausal women with estrogen- and/or progesterone-receptor-positive, HER2-negative early breast cancer who have an intermediate to high clinical risk but low genomic risk of recurrence based on MammaPrint4 testing. The study aims to understand the real-world use of ovarian function suppression (OFS) combined with endocrine therapy, with or without prior chemotherapy, and how secondary amenorrhea after chemotherapy might affect outcomes. It also focuses on treatment adherence and quality of life over time, given the importance of long-term endocrine treatment up to 10 years. The registry will follow patients receiving standard-of-care treatment, which may include endocrine therapy with or without ovarian function suppression, and potentially chemotherapy based on clinical decisions. Data on treatment choices, including the use of OFS and chemotherapy, will be collected along with tumor characteristics assessed by local pathology and genomic signatures. Quality of life assessments will be conducted at baseline and multiple time points up to five years, while treatment adherence and outcomes will be tracked over up to 10 years. Participants will provide baseline information including tumor and treatment details. Researchers will collect follow-up data on treatment adherence, quality of life using specific questionnaires, and disease outcomes such as the five-year distant recurrence-free interval. Monitoring will include hormonal status and clinical assessments to correlate treatment effects with genomic risk scores and clinical markers. The overall goal is to improve understanding of treatment patterns and outcomes in this specific breast cancer population under real-world conditions.
