Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Males, age 18 to 65 years.
  • Subjects with Severe Hemophilia A with a documented plasma FVIII level of \< 1%
  • ≥ 150 exposure days with FVIII concentrate(s) as supported by medical records

Exclusion criteria

Exclusion Criteria:

  • Evidence of current or past inhibitor antibody:
  • History of any congenital or acquired coagulation disorders other than hemophilia A.
  • count \<75,000/mm*3.
  • Abnormal renal function (serum creatinine >2 x the ).
  • Active liver disease verified by medical history or persistently elevated or aspartate aminotransferase >5 x the upper limit of the normal range or severe liver disease as evidenced by, but not limited to any of the following: >1.4, hypoalbuminemia, portal vein hypertension including presence of otherwise unexplained splenomegaly and history of esophageal varices.
Terms in these criteria, in plain language(4)

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.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

ULN (upper limit of normal)

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.

ALT and AST (liver enzymes)

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.

INR, PT and aPTT (clotting tests)

Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.

Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Nov 2017 to primary completion in Jan 2018, 1 month.

Of 37 industry-sponsored phase 1 interventional studies under Hemophilia A, half reached primary completion within 10 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 18. This study's 1 month is below that.

Counting every sponsor, half of 46 studies reached it within 13 months; a quarter within 7 and three quarters within 26.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 9, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
