Summary

This study is testing a drug called Nuwiq, a lab-made clotting factor, to prevent excessive bleeding during major surgery in women and girls with hemophilia A. About 28 participants will receive Nuwiq around the time of their surgery. Researchers will check if the drug successfully controls bleeding during and after the operation.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Nuwiq (a lab-made clotting factor VIII)
What this could lead to
If successful, this could confirm that Nuwiq is a safe and effective option to control bleeding during surgery for women and girls with hemophilia A.
What could go wrong
This is a small, single-group study with only 28 participants, so results may not apply to everyone. As a phase 4 trial, it is confirmatory, but unexpected side effects or lack of efficacy are still possible.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: 1. Women/girls with haemophilia A (FVIII:C ≥1-\<40%) according to medical history. Additionally, women/girls with documented FVIII activity levels between ≥ 40% and 50% may be included if there is a documented history of clinically significant bleeding episodes consistent with haemophilia A; and/or either documented prior treatment with FVIII concentrates or a clinical indication that FVIII treatment would have been appropriate (e.g., use of FVIII from a family member, or treatment with alternative haemostatic agents due to access limitations) 2. At least 12 years of age 3. Scheduled to undergo major surgery\* requiring FVIII treatment, including elective and emergency procedures and caesarean section in pregnant women with haemophilia A 4. Freely given written informed consent of the patient, or parent/legal representative where applicable, obtained in accordance with local regulations Exclusion Criteria: 1. Coagulation disorder other than haemophilia A 2. Present or past FVIII inhibitor (≥0.6 Bethesda units \[BU\]/mL) 3. Severe liver or kidney disease (alanine aminotransferase \[ALT\] and/or aspartate aminotransferase \[AST\] levels \>5 times the upper limit of normal; or creatinine \>120 μmol/L) 4. Known hypersensitivity to Nuwiq's active substance or its excipients (sucrose, sodium chloride, calcium chloride dihydrate, arginine hydrochloride, sodium citrate dihydrate, poloxamer 188) 5. Pregnancy, except in participants with a planned caesarean section 6. Already had surgery in this study 7. Current participation in another interventional clinical trial 8. Treatment with any investigational medicinal product (IMP) within 30 days prior to screening visit
