About

The study will involve patients with chronic immune thrombocytopenia. This disease is diagnosed in the presence of isolated thrombocytopenia (decrease in platelet count only), except for other reasons. The addition of "chronic" means that the disease lasts more than 12 months. Patients included in the study will receive Bioven, 10% solution for infusion according to the protocol for the use of IVIG in ITP - at a dose of 0.8-1.0 g / kg 1 time per day for 2 consecutive days, the course dose of 1.6-2.0 g / kg according to the "Guideline on the clinical investigation of human normal immunoglobulin for intravenous administration (IVIG)", rev. 3, 28 June 2018. After administration of the investigational drug, patients will be under medical supervision for 28 days. The stay of patients in the study - at least 4 weeks.

Full description

The investigational drug, IVIG, is used for immunomodulatory therapy in the treatment of autoimmune diseases. The study will involve patients with chronic immune thrombocytopenia. This autoimmune disease is diagnosed in the presence of isolated thrombocytopenia (decrease in platelet count only), except for other reasons. The addition of "chronic" means that the disease lasts more than 12 months. Screening stage The patient or her legal representative must sign an informed consent. After the informed consent signing procedure, the patient is screened and assessed for compliance with the inclusion and non-inclusion (exclusion) criteria. Clinical stage After the patient is included in the study, according to the protocol, he/she is hospitalized and the study drug is administered at a dose of 0.8-1.0 g/kg once a day for 2 days (the course dose is 1.6-2.0 g/kg). The next day after the administration of the drug, the patient undergoes blood sampling to determine the level of platelets, the level of immunoglobulin G (IgG) and the Coombs test. This procedure will also be carried out on days 7, 14, 21 and 28 after the first injection of the drug to monitor the patient's performance. The final stage The blood sampling procedure to determine the above indicators will be carried out on days 7, 14, 21, and 28 after the first administration of the drug to monitor the patient's performance.
