Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Safety assessment by evaluation of adverse events (AEs) and abnormal laboratory results
Safety assessment, including the incidence of all reported AEs and abnormal laboratory results was done. All AEs were classified based on the Medical Dictionary for Regulatory Activities (MedDRA Desktop Browser 4.0 Beta) terms as System Organ Class (SOC) and Preferred Term (PT). All the reported events were graded according to the Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). Moreover, seriousness of AEs was assessed according to International Council for Harmonization (ICH-E2B) guidelines. The causality relation was assessed based on the World Health Organization (WHO) criteria.
Time frame: Adverse events collection and documentation was done during the study (up to 28 days)
Immunogenicity assessment
Immunogenicity of factor viii was evaluated at scheduled visits by blood sampling to determine the production of inhibitor against factor viii.
Time frame: Immunogenicity sampling was done at screening visit and day 7, 12 and 28
Ran from Jul 2023 to primary completion in Sep 2023, 2 months.
Of 89 industry-sponsored phase 3 interventional studies under Hemophilia A, half reached primary completion within 32 months of starting (the median), counting those still running; a quarter within 18 and three quarters within 56. This study's 2 months is below that.
Counting every sponsor, half of 91 studies reached it within 33 months; a quarter within 20 and three quarters within 56.
