Caring for patients with hemophilia B?

Consider the Honey-B study

A study is currently underway to evaluate disease characteristics in hemophilia B patients receiving FIX replacement therapy. Consider Honey-B as an opportunity for your male patients to contribute to hemophilia B research.


Honey-B is a study that aims to evaluate disease characteristics in hemophilia B patients receiving FIX prophylaxis. The aim of the study is to gather at least 6 months of information on bleeding events for each individual participant while they continue to use their usual FIX replacement therapy. There is no experimental treatment being tested in this study. The study is informational and part of a larger program to understand and treat hemophilia B with an experimental therapy in the future. Participants enrolled in this study may be offered the opportunity to enrol in a subsequent clinical trial investigating the safety, tolerability and efficacy of an investigational treatment.

Patients are expected to participate in this study for a minimum of 6 months and up to 2 years, with the duration of the study being dependent on the availability of opportunities to enrol in a subsequent clinical trial. During the study, participants will have at least 6 and up to approximately 9 study visits, depending on the duration of the study.


Qualified participants may also be compensated for certain travel and food costs that are related to study visits.

How can you help?

Honey-B is enrolling approximately up to 120 people with hemophilia B. The success of Honey-B depends on physicians to refer potential study participants. Your patients may be eligible if they are:

The study team will check your patient’s full medical history to see if they meet all inclusion criteria. Diversity in studies is critical to developing better treatments – help ensure that your patients are represented.


If you have potentially eligible and interested patients, allow them to contribute to hemophilia B research and discuss the Honey-B study. You may also contact the nearest study site to refer them.
