KN057 Multiple Dose Study in Moderately Severe to Severe Hemophilia

Hemophilia

This study is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics and efficacy of multiple subcutaneous doses of KN057 in subjects with hemophilia A or B, with or without inhibitors to Factor VIII (FVIII) or Factor IX (FIX). 24 adult participants 18 to 70 years of age with moderately severe to severe hemophilia A or hemophilia B (defined as FVIII or FIX activity ≤2%, respectively) with or without inhibitors (including 18 HA/HB patients without inhibitors and 6 HA/HB patients with inhibitors) are expected to be enrolled in this study during which they will receive prophylaxis treatment (defined as treatment by SC injection once weekly of KN057).

Does the Thrombin Generation Test Performed During the Pharmacokinetic Profile of the Substitutive...

Hemophilia

In the context of hemophilia, it is well know that the level of factor VIII alone does not reflect the clinical phenotype of the patients in an accurate way. At equal factor VIII levels, certain patients will bleed more than others. The thrombin generation test (TGT) is a test that seems to provide a better prediction of the overall hemostatic status of an individual patient. In a previous study, the investigators have established normal reference values of the thrombin generation curve in children aged 6 months to 16 years and adults. The goal was to evaluate the use of this test in different clinical contexts and in severe hemophilia patients in particular. A pilot study showed that the patients having a thrombin generation <150 had a severe phenotype, whether those who received an appropriate prophylaxy had a thrombin generation superior to 150. Moreover, the investigators now have access to a software tool that allows them to individually determine the pharmacokinetic profile of the factor VIII injected to each patient. The factor VIII concentration is measured at injection and 30 minutes, 1 hour, 2 hours and 24 hours afterwards. The introduction of these concentrations in the software allows to obtain the half-life of factor for a given patient, the maximum peak, and the minimum factor level (though level). The injected dosis might be sufficient (disappearance of substantial diminution of the bleedings) or unsufficient (persisting bleeding) for a given patient. This study aims: to measure the pharmacokinetic profile of factor VIII by two different methods, the time-based method and the chromogenic method to correlate the results with the TGT results obtained at the same time points and determine which method gives the best correlation to link the clinical symptomatology (improved symptomatology or not) with the TGT results to determine which minimal TGT result is linked to a minimal bleeding rate to adapt the prophylactic dosis of the patient in a personalized way.

A Study to Determine How a Virtual-reality Based Solution May Reduce the Treatment Burden of Children,...

Hemophilia A

The main aim is to describe how the treatment burden and challenges of participants, relatives, and doctors during regular Factor VIII infusions to treat hemophilia evolve using a virtual-reality (VR) based solution. The study also aims to find out how well the VR based solution is tolerated and how satisfied the participants, relatives, and doctors are with it. The VR based solution includes a mobile phone app and a 3D mask. Participants will use the VR based solution while receiving prophylactic Factor VIII infusions for 4 weeks at home. Participants will visit the clinic for the last infusion; at this time data will be collected from participants, relatives, and doctors

Factor IX as Adjunctive Therapy to Emicizumab (EMIX)

Hemophilia A

This trial will enroll patients with severe hemophilia A. Experiments will be run in vitro by spiking patients' blood with different molecules (currently used and theoretically proposed as adjunctive therapy to emicizumab), therefore no more than minimal direct risk to patients is expected. This is a pilot preclinical study.

An 18-month Low-interventional Study to Assess Joint Health in Haemophilia A and B Patients on Prophylaxis...

Hemophilia AHemophilia B

The goal of this low-interventional study is to describe the overall joint health in patients with haemophilia A or haemophilia B prophylactically treated with rFVIIIFc or rFIXFc. The main question it aims to answer is the: • Evaluation of the overall joint status as detected by ultrasound in haemophilia A and B patients treated with rFVIIIFc or rFIXFc prophylaxis over the 18-month study period. Participants will come to 6-monthly visits during the 18-month long study period and will perform an ultrasound with the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) protocol at each visit. At baseline and end of study visits, the patients will be assessed with the clinical scoring system Haemophilia Joint Health Score (HJHS) and complete patient questionnaires. Retrospective data from patient medical records will also be collected for at least 6 months before enrolment in the study.

Personalized Medicine for Canadians With Hemophilia

Hemophilia AHemophilia B

Performing an individual pharmacokinetic (PK) estimate is only the first step in implementing tailored prophylaxis, which requires using the PK profile information to design a personalized treatment regimen matching the treatment needs of individual patients. The overarching goal of WAPPS-Hemo is to provide an easy-to-use web application supporting all the steps needed to accomplish tailoring care of individual patients by matching their unique characteristics to the most appropriate treatment regimen, realizing the promise of personalized medicine. This study will assess the impact of adopting population PK (popPK) based tailored prophylaxis in clinical practice, including proportion of patients eligible for tailoring, and encountered barriers. The impact on patient important outcomes and on societal outcomes, particularly financial impact, vs. current standardized regimens will be measured. It is hypothesized that WAPPS-Hemo, via estimation of precise individual PK profiles and by supporting the simulation of treatment regimens will: improve or maintain patient important outcomes, while reducing wastage of factor concentrates; and establish best practices and effective knowledge translation strategies for the implementation of personalized medicine. Additionally, a solid base of data will be generated to model the bleeding risk of severe hemophilia A/B patients undergoing tailored prophylaxis which will enable evaluation of a combination of patient and treatment characteristics predictive of individual bleeding risk.

A Research Study Investigating Nonacog Beta Pegol (N9-GP) for Treatment and Prevention of Bleedings...

Haemophilia B

The study investigates how well the medicine called nonacog beta pegol (N9-GP) works in Chinese people with haemophilia B. Participants will be treated with N9-GP. This is a medicine that doctors can already prescribe in other countries. The medicine will be injected into a vein (intravenous injection). At the visits to the clinic, the medicine will be injected by the study doctor. When treating themselves at home, participants inject the medicine using a needle and vial set. The study will last for about 12-16 months. The participants will have between 9 and 19 visits to the clinic and possibly also some phone calls with the study doctor. At all visits to the clinic, the participants will have blood samples taken.
