Post-Marketing Surveillance To Observe Safety And Efficacy Of Xyntha Solofuse Prefilled Syringe

106 participantsStarted 2017-01

Plain-language summary

This study aims to observe the safety and efficacy of the Xyntha Solofuse prefilled syringe in the setting of routine practice. The primary objective is to detect medically significant events (factor VIII inhibitor). The secondary objective is to observe the overall efficacy and safety of the Xyntha Solofuse prefilled syringe including serious adverse events. In this open-label, non-comparative, observational, non-interventional, retrospective and multi-center study, post-marketing surveillance data will be collected retrospectively for up to 6 months from the initial administration day of the Xyntha Solofuse prefilled syringe injected into patients who have been administered the Xyntha Solofuse prefilled syringe. As specified in the product approval issued by the Ministry of Food and Drug Safety, the study will be conducted for 4 years from the approval date. At least 600 study subjects will be enrolled in this study to meet the MFDS requirements. Although 600 is the assigned number of study subjects, the number of cases will be adjusted considering the actual number of enrolled subjects after the study start day.

Inclusion criteria

. Hemophilia A (congenital factor VIII deficiency) patients who have been administered according to the indication of the product 1) Control and prevention of bleeding episodes and for routine and surgical prophylaxis in patients with hemophilia A (congenital factor VIII deficiency) 2) This drug does not contain von Willebrand factor and, therefore, is not indicated in von Willebrand's disease

Exclusion criteria

. Patients who have a history of hypersensitivity to the Xyntha Solofuse prefilled syringe or the ingredients of this drug.
. Patients who have a history of hypersensitivity to hamster proteins.
. Patients who have bleeding disorders other than hemophilia A.
. Patients who have a history of FVIII inhibitors, or currently have or are suspected of having FVIII inhibitors. In case inhibitor titers quantified in Bethesda Units in the laboratory test results are within the normal laboratory range or at least 0.6 BU/mL. If laboratory tests cannot be performed, the investigator will determine whether or not inhibitors exist based on the clinical assessment results that show a decrease in efficacy of the replacement of FVIII (e.g. bleeding at least once, if the replacement of anti-bleeding agents is needed to be administered, and if frequency or dosage of replacement FVIII therapy needs to be increased).

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
