Research question:
Whether there are the changes in quality of life in patients with haemophilia A after switching from SHL FVIII prophylaxis to efmoroctocog alfa prophylaxis?
A 12-month prospective open-label, single-arm multicentre study. Evaluation of parameters will be carried out on the backdrop of patient treatment in the settings of routine medical practice. No medical examinations/ procedures/ treatment(s) on the top of regular medical practice are planned, except fixed time of examinations.
Quality of life is among the key factors when medical decision about management of haemophilia is taken. There are no scientific data on the HRQoL in patients after switching from Standard Half Life (SHL) FVIII prophylaxis to efmoroctocog alfa (Extended Half Life, EHL) prophylaxis in Russia.
It will be a 12-month prospective open-label, single-arm multicentre study. Evaluation of parameters will be carried out on the backdrop of patient treatment in the settings of routine medical practice. No medical examinations/ procedures/ treatment(s) on the top of regular medical practice are planned, except fixed time of examinations. Providing the centers/ patients with the study drug (efmoroctocog alfa) may be considered as interventional component, whereas all administrations should be in accordance with Instruction on Medical Use approved by Russian Ministry of Health.
Research question:
Whether there are the changes in quality of life in patients with haemophilia A after switching from SHL FVIII prophylaxis to efmoroctocog alfa prophylaxis?
No hypothesis is formulated for this exploratory study. The obtained data will be used to assess real world data on quality of life and clinical outcomes in patients with haemophilia A after switching from SHL FVIII prophylaxis to efmoroctocog alfa prophylaxis in routine medical practice in Russia
