Sponsored by Novo Nordisk A/S · Phase 3, Interventional, and Treatment
The purpose of this study is to find out if denecimig is safe and effective for treating people who have acquired haemophilia A. Participants will be in this study for up to around 1 year and 5 months (73 week).
844 studies on the registry are indexed under Hemophilia A; 138 are open to participants now.
This study's planned enrollment of 84 is above the median of 30 across 499 interventional studies indexed under Hemophilia A.

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.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
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.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Started Oct 2026 (actual). Primary completion is estimated for Mar 2029, 29 months after the start.
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 planned 29 months is close to that.
Counting every sponsor, half of 91 studies reached it within 33 months; a quarter within 20 and three quarters within 56.
