Clinical Trial Summary

In the prospective part of the study, patients diagnosed with PID will receive replacement therapy with Cutaquig for at least 6 months and will be randomised with the help of physicians of the Russian PID Registry. At the beginning of the study, data on the prior intravenous immunoglobulin (IVIG) therapy efficacy will be extracted from patients' medical records (retrospective part of study). Also, at the beginning of the study, patients or their parents will be asked to complete Quality of Life Questionnaire for children, version 4.0; short form in Russian - Pediatric Quality of Life Inventory Russian, Version 4.0 (Russia), PedSQL (Appendix 14.1). During the 6 months of treatment with Cutaquig, investigators will enter information on infectious episodes, IgG levels (at least 3 times during the study period), and definition of an adverse drug reaction / serious adverse drug reaction, in the database. After 6 months, patients/their parents will be asked to complete the PedSQL, Quality of Life Questionnaire again. If the patient continues to receive the drug, and patient and his/her legally acceptable representatives (for patients under 14 years of age) agree to continue participating in the study, similar information will be collected for another 6 months. The first 6 months are planned for the main study period, 6-12 months for an extended study period. Data obtained in the prospective phase of the study will be compared with similar data obtained in the retrospective phase in the same patients

Description:

In the prospective part of the study, patients diagnosed with PID will receive replacement therapy with Cutaquig for at least 6 months and will be randomised with the help of physicians of the Russian PID Registry. At the beginning of the study, data on the prior intravenous immunoglobulin (IVIG) therapy efficacy will be extracted from patients' medical records (retrospective part of study). Also, at the beginning of the study, patients or their parents will be asked to complete Quality of Life Questionnaire for children, version 4.0; short form in Russian - Pediatric Quality of Life Inventory Russian, Version 4.0 (Russia), PedSQL (Appendix 14.1). During the 6 months of treatment with Cutaquig, investigators will enter information on infectious episodes, IgG levels (at least 3 times during the study period), and definition of an adverse drug reaction / serious adverse drug reaction, in the database. After 6 months, patients/their parents will be asked to complete the PedSQL, Quality of Life Questionnaire again. If the patient continues to receive the drug, and patient and his/her legally acceptable representatives (for patients under 14 years of age) agree to continue participating in the study, similar information will be collected for another 6 months. The first 6 months are planned for the main study period, 6-12 months for an extended study period. Data obtained in the prospective phase of the study will be compared with similar data obtained in the retrospective phase in the same patients. Considering the lack of the study drug marketing authorisation in the Russian Federation, study drug doses and treatment regimens were chosen as per current clinical practice and instructions for human use approved in other countries. Conventionally, on switching from IVIG therapy, the subcutaneous immunoglobulin products are administered at the same monthly dose (0.4-0.8 g/kg), evenly divided into 3-5 administrations per month, subject to monitoring of the pre transfusion IgG level with target IgG values of at least 7 g/L. All this information will be reflected in the Case record forms (CRF). Besides, information about therapeutic strategies, such as dose change or therapy change, will also be entered in the CRF.
