The Second Multicenter Hemophilia Cohort Study

United States, Brazil, Canada2,565 participantsStarted 2001-04-27

Plain-language summary

The Second Multicenter Hemophilia Cohort Study (MHCS-II) will evaluate and prospectively follow approximately 4500 persons with hemophilia who were exposed to hepatitis C virus (HCV). The vast majority will have been infected with HCV, and approximately 1/3 will have been infected with human immunodeficiency virus (HIV). Primary objectives are to quantify the rates of liver decompensation, hepatocellular carcinoma, and non-Hodgkin lymphoma and to evaluate candidate clinical, genetic, virologic, serologic and immunologic markers that are likely to be on the causal pathway for these conditions. Candidate clinical and laboratory markers will be examined longitudinally to define changes over time and their relationships to one another. Collaborative studies will focus on genome scanning and evaluation of candidate genetic loci for susceptibility or resistance to HCV and HIV infections or to the diseases that result from these infections. Additional studies will identify response and complication rates of various anti-HCV and anti-HIV regimens in the setting of comprehensive clinical care of persons with hemophilia.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

* INCLUSION CRITERIA: Must be registered patient with an inherited coagulation disorder at a participating MHCS-II center. Disorders include hemophilia A or B (congenital factor VIII or IX deficiency), deficiencies in other factors such as V or XI, and vonWillebrand's disease. (Unless noted otherwise, all of the disorders will collectively be referred to as hemophilia .) All such hemophilia and vonWillebrand s disease patients are to be recruited as study participants. Since January 1, 1993, must have had at least one positive result on a licensed assay for HCV antibodies, HIV antibodies, or HIV RNA. Must be at least 13 years of age at enrollment. Must provide signed informed consent or, for minors, signed assent plus signed informed consent from the parent or guardian. EXCLUSION CRITERIA: Is not a patient with an inherited coagulation disorder. Does not have a positive test for HCV antibodies, HIV antibodies, or HIV RNA on a licensed assay performed since January 1, 1993. Is less than 13 years of age. Lacks informed consent/assent.

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.
