Mastocytosis

This is an open-label, two-part Phase 2 study investigating CGT9486 for the treatment of patients with Advanced Systemic Mastocytosis (AdvSM), including patients with Aggressive SM (ASM), SM with Associated Hematologic Neoplasm (SM-AHN), and Mast Cell Leukemia (MCL).

This is a randomized, double-blind, placebo-controlled, Phase 2/3 study comparing the efficacy and safety of elenestinib (BLU-263) + symptom directed therapy (SDT) with placebo + SDT in participants with indolent systemic mastocytosis (ISM) whose symptoms are not adequately controlled by SDT. Parts 1 and 2 will enroll participants with ISM. Participants enrolled in Part 2 will roll over onto Part 3 to receive treatment with elenestinib in an open-label fashion following completion of the earlier Part. Part K will enroll participants with ISM who have previously received an approved selective KIT inhibitor. The study also includes pharmacokinetic (PK) groups that will enroll participants with ISM.

Study Description: Affected and unaffected members of families with familial hypereosinophilia (FE) will be enrolled and evaluated on this protocol. For affected family members, a thorough clinical evaluation will be performed with emphasis on potential sequelae of eosinophil-mediated tissue damage. Blood cells, bone marrow and/or serum will also be collected to provide reagents (such as DNA, RNA, and specific antibodies) for use in the laboratory to address issues related to the genetic and immunologic basis of FE as well as its pathogenesis. It is anticipated that affected family members will undergo a more extensive evaluation than is generally available and that the specimens collected from them will prove to be valuable reagents for laboratory studies related to eosinophilia, eosinophil activation and function. While the study is not designed to address the question of therapy for FE, in patients for whom medical therapy is indicated (for either the hypereosinophilia itself or its sequelae), appropriate treatment will be instituted by our clinical service or the patients local physicians. No experimental chemotherapy is involved in this protocol. Unaffected family members will provide research specimens on this protocol to help determine the underlying genetic causes of FE. Objectives: Primary Objective: To study the natural history of familial hypereosinophilia (FE) Secondary Objectives: 1. To determine the immunologic and molecular mechanisms responsible for eosinophilia, eosinophil activation, and pathogenesis in FE 2. To identify early clinical or laboratory markers of disease progression Endpoints: Primary Endpoint: Development of eosinophilic end organ manifestations Secondary Endpoints: 1a. Description of immunologic features of FE. 1b. Identification of genetic driver(s) of FE 2\. Identification of clinical or laboratory markers that become abnormal prior to disease progression in FE

This is a non-interventional study assessing the effectiveness of avapritinib (BLU-285) in the management of ISM in real-world settings in Germany. The study also seeks to address the existing data gap in the natural history and management of participants with ISM. The study is designed to follow each participant up to a maximum of 24 months.

C-Kit is involved in an essential pathway of disease occurrence and is closely related to the poor prognosis of patients. However, the clinical significance of c-Kit mutation as molecular MRD monitoring is still unclear. What are the differences and advantages of using c-Kit mutation as MRD in prognostic assessment compared with other MRDs (MFC or RUNX1::RUNX1T1) widely used today? Existing data suggest that patients with one positive and one negative MRD results obtained by two different techniques have a higher risk of recurrence than patients with two negative MRD results but a lower risk of recurrence than patients with two positive MRD results. Therefore, can combining multiple MRD markers, including c-Kit mutations, overcome the shortcomings of a single molecular marker as MRD monitoring? Therefore, this project intends to confirm the clinical significance of quantitative detection of c-Kit mutation as MRD in acute myeloid leukemia.

CP-MGD024-01 is a Phase 1, open-label, multi-center study of MGD024 as a single agent in participants with select blood cancers that have not responded to treatment with standard therapies or who have relapsed after treatment. The study is designed to determine the safety, tolerability, pharmacokinetics (affect of the body on the drug), pharmacodynamic (affect of the drug on the body), immunogenicity (development of antibodies against the drug), and preliminary anti-cancer effect of MGD024. Participants will receive treatment with MGD024 in consecutive 28-day cycles for a study treatment period of up to 12 cycles (approximately 1 year) or until treatment or study discontinuation criteria are met. Response assessments will be performed after Cycle 1 and then after every even numbered cycle starting with Cycle 2 until progression or study treatment discontinuation. Participants will be checked for side effects throughout the study.

This is a Phase I/II, open-label multicenter study to evaluate the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of anti-GPRC5D CAR-T cell product (OriCAR-017) in subjects with relapsed/refractory multiple myeloma". The study will consist of a Phase I dose escalation stage involving three doses as a single IV infusion) with up to 18 evaluable subjects and a dose expansion stage with 10-15 evaluable subjects, followed by a Phase II stage with up to 48 evaluable subjects.

Study Description: This study is designed to collect data and clinical samples from participants with elevated eosinophil counts in the peripheral blood or tissues or their relatives to enhance our understanding of the mechanisms driving eosinophilia and eosinophil activation in patients with a wide range of eosinophilic disorders with the ultimate goal of improving diagnostics and identifying novel treatment modalities for these patients. Eosinophilic participants will undergo an extensive clinical evaluation at baseline and at least yearly thereafter focused on the identification of the cause of eosinophilia and the presence of end organ manifestations. Blood, bone marrow, tissue, and/or body fluids will be collected for research purposes at initial and follow-up visits to address broader questions relating to the varied etiologies of eosinophilia, biomarkers of disease activity and eosinophil activation, and the functional role of eosinophils in homeostasis and disease pathogenesis. While this protocol is not primarily designed to study treatment of eosinophilic patients, the clinical and immunological responses to therapy will be monitored. This protocol will also allow clinical and laboratory evaluation of family members of subjects with eosinophilia to help identify genetic causes of eosinophilia and to provide controls for immunologic studies.

The AIDA registry service is based on REDCap (Research Electronic Data Capture, project-redcap.org), a secure web application for building and managing online surveys and databases, designed to support data capture for research studies. The platform is directly accessible through the AIDA website, after inserting a personal username and password. Currently, 11 registries are available, each one dedicated to the collection of data about: * monogenic AID * PFAPA syndrome * undifferentiated systemic AID (USAID) * Behçet's disease * Schnitzler's disease * VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome * Still disease * noninfectious uveitis * noninfectious scleritis * spondyloarthritis * Castleman disease The registry will pursue the following aims within the first 36 months from the start of the enrollment: 1. to identify any association between clinical manifestations and gender, disease duration, body mass index and tabagism; 2. to detect differences in the clinical phenotype between pediatric-onset and adult-onset patients; 3. to identify the impact of different treatment approaches on clinical and laboratory disease manifestations. Additional aims of the AIDA project, to be reached over the next 10 years, are the following: 1. to overcome fragmentation in the clinical experience on these rare conditions by sharing the knowledge at the international level; 2. to improve knowledge about the clinical presentation, genotype-phenotype correlations, response to treatment, long-term complications and social impact when monogenic and polygenic AID manifest during either childhood or adulthood; 3. to identify the long-term clinical course of patients diagnosed with monogenic or polygenic AID; 4. to promote awareness among physicians and enhance early recognition of these diseases; 5. to describe the impact of AID on quality of life; 6. to identify any impact of monogenic and polygenic AID on fertility; 7. to study the course of AID during pregnancy; 8. to assess the socioeconomic impact of AID; 9. to promote future multicentric studies. Data collection is both retrospective and prospective. It includes demographic, clinical, diagnostic, genetic, clinimetric, laboratory, radiologic, therapeutic and socio-economic data. Instruments are designed to be filled out during routine clinical visits, usually scheduled every 3-6 months. Separation of personally identifiable information and medical data by using only pseudonyms for storing medical data ensures compliance with data protection regulations. The description of symptoms, diseases, procedures and injuries is based on the International Statistical Classification of Diseases and Related Health Problems (ICD)-10 coding system. Data management is both central and decentral. Data are extracted and statistically analyzed on a regular basis according to individual study protocols. A policy for authorship and dissemination of research findings is in place among the AIDA partners contributing to the registry. The AIDA registry will support data collection for the conduction of clinical trials, observational studies, comparative effectiveness research, and other research on patients with monogenic and polygenic AID. Several healthcare providers contributing to the AIDA Network are members of the European Reference Network (ERN) for Rare Immunodeficiency, Autoinflammatory and Autoimmune Diseases (RITA).
