Status Not yet recruiting

Clinical Trial Summary

To establish a population pharmacokinetic and pharmacodynamic model of rituximab in children with hemopathy. To optimize the administration of rituximab in the treatment of children based on pharmacokinetic model.

Clinical Trial Description

hemotherapy for children with lymphoma: rituximab (375mg/m2 BSA) was added intravenously from COPADM1 regimen. once every 3 weeks to 4 weeks, combined with corresponding chemotherapy, a total of 4 times. Rituximab (375mg/m2 BSA) was administered intravenously for lymphoproliferative diseases and Epstein-Barr(EB) virus-associated B lymphoproliferative diseases after hematopoietic stem cell transplantation. Once a week, a total of 4 times. Primary immunologic thrombocytopenic purpura(ITP) and autoimmune hemolytic anemia(AIAH) patients received rituximab (100mg/m2 BSA) intravenously once a week, a total of 4 times. The children were divided into group A and group B according to the disease type, and each group was randomly divided into two groups (group 1 and group 2) and assigned blood collection points. Burkitt's lymphoma diffuse large B-cell lymphoma follicular lymphoma and other mature B-lymphomas were in group A. Hematopoietic stem cell transplantation, EPstein-Barr virus associated lymphocyte proliferative disease, lymphocyte proliferative change, primary immunologic thrombocytopenic purpura(ITP) and autoimmune hemolytic anemia(AIAH) were in group B. Group 1: Children in the first group were collected 0, 12, 24, and 72 h after the first dose, 0h before and after the second dose, 0h before and after the third dose, 0h before and after the last dose, 48, and 96 h after the last dose. Venous blood was collected at 12 time points. Group 2: Children in the second group were collected 0, 12, 48, and 96 h after the first dose, 0h before and after the second dose, 0h before and after the third dose, 0h before and after the last dose, 24, and 72 h after the last dose. Venous blood was collected at 12 time points. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
