Clinical trials

The goal of this study is to see if the drug balstilimab is safe and effective in participants with relapsed/refractory lymphomas. Participants will receive balstilimab every 3 weeks and their outcomes will be assessed periodically.

Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN) is a very rare hematologic malignancy. Despite recent advances, at present there is no consensus on the optimal treatment of BPDCN. The optimal therapy of disease remains to be determined, and due to the rarity of cases, there is a need for international collaboration to collect data on BPDCN clinical presentations, diagnostics, treatment regimens and outcomes. Therefore, the objectives of this study are: (1) to build a large database of patients with BPDCN, (2) to investigate the characteristics and outcome of the disease with different treatment regimens, (3) to evaluate prognostic factors, and (4) to generate data-based prospective treatment recommendations.

Primary cardiac angiosarcomas (PCA) are highly aggressive malignant heart tumors arising from the endothelial cells (ECs) lining the blood vessels of the heart and account for approximately 25%-30% of all primary cardiac malignancies. It is considered to be the most fatal and aggressive primary cardiac malignancy. This international registry aims to establish a large multicenter database of patients with cardiac angiosarcoma. Our objectives are: 1. Collect clinical data, including demographics, medical history, treatments, and outcomes, to build a comprehensive database. 2. Analyze data to evaluate and identify genetic, environmental, or lifestyle risk factors for cardiac angiosarcoma. 3. Evaluate the effectiveness of various treatments (surgery, chemotherapy, immunotherapy, radiation) to inform best practices. 4. Develop evidence-based guidelines and recommendations for prevention, diagnosis, treatment, and management based on registry data.

Central nervous system (CNS) tumors are the most common solid malignancies among children. Although some types of CNS tumors like medulloblastomas and low-grade gliomas are widespread and well-studied, there is a huge number of rare diseases that need further research. This international registry aims to establish a large multicenter database of pediatric and young adult patients with rare embryonal tumors of the central nervous system and describe the clinical presentations, diagnostics, treatment regimens, and outcomes. Embryonal tumors with multilayered rosettes (ETMR), FOXR2-activated CNS neuroblastoma, cribriform neuroepithelial tumor, and CNS tumor with BCOR internal tandem duplication are extremely rare embryonal tumors some of which were first described in the last edition of the World Health Organization (WHO) Classification of Tumors of the Central Nervous System. Objectives of the registry are 1) to evaluate prognostic factors, 2) to identify diagnostic and treatment gaps, 3) to investigate the characteristics and outcome of the disease with different treatment regimens, and 4) to generate data-based prospective diagnostic and treatment recommendations.
