Summary: This phase II trial compares mosunetuzumab to the usual treatment (rituximab) for improving survival in patients with nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). Rituximab and mosunetuzumab are monoclonal antibodies. They bind to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cel...

Objective: * To develop the data collection infrastructure required to prospectively collect longitudinal electronic patient-reported outcomes (PROs) survey instruments in adult and pediatric patients diagnosed with NLPHL. Secondary Objective: * To examine differences in baseline and longitudinal changes in PROs based on disease characteristics, disease status, and treatment strategies among adult and pediat...

Summary: Lymphomas are a group of cancers that originate in the lymphatic system, a key component of the immune system. They can be broadly categorized into two main types: Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL). There are different subtypes of HL, including classical Hodgkin lymphoma (cHL) and nodular lymphocyte-predominant Hodgkin lymphoma (NLPHL). The subtypes of cHL include nodular sclero...
