Introduction: Haemophilia management and patients’ quality of life significantly improved. However, data on current patients’, caregivers’ and clinicians’ satisfaction and limitations of treatments and haemophilia management are limited. Aim: Assessing the management satisfaction and unmet needs from the perspective of Italian patients with haemophilia (PWH) without inhibitors (or caregivers if children) and of specialist physicians. Methods: Surveys (for patients≥18 years, caregivers of children and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. Results: Among 275 participants, 120 (43.6%) were PWH without inhibitors, 79 (28.7%) caregivers and 37 (13.4%) clinicians. Patients and caregivers perceived a higher control of the disease compared to clinicians. However, more than 40% of patients and caregivers reported to feel significantly conditioned by the risk of bleeding during their daily life. PWH reported a 6-month mean/median (range) of bleeds 2.3/.0 (0-24) and caregivers 1.3/.0 (0-16) in children. The treatment burden (frequency of administration) was not satisfactory for more than half adults and caregivers of children treated with prophylaxis. A good access to treatment, haemophilia centres and medical service was reported, with issues associated to the multidisciplinary approach and treatment at emergency department. Conclusions: This large national study provides an updated overview of haemophilia care in Italy from different points of views, highlighting positive aspects and unmet needs. This information can guide future interventions to improve haemophilia management and the assessment of impact of new treatment options.

BACKGROUND Immune tolerance induction (ITI) is the only proven strategy to eradicate factor VIII inhibitors in patients with haemophilia A (HA). AIM To identify patients and treatment options with the highest chance of inhibitor eradication by primary ITI. PATIENTS AND METHODS In the frame of the Italian ITI Registry, carried out from 1995 to 2015 (last follow-up 2018), 137 primary ITI courses in severe HA patients (90/137 with poor prognosis) were analysed for predictors of outcome (complete/partial response or failure). Sixty-six of them (48%) were prospectively evaluated. RESULTS ITI was successful in 91/137 patients (66.4%) and 70 (51.1%) achieved complete response within 11 months (median). Historical peak titres ≤200 BU/ml (P = .033), inhibitor titres ≤5 BU/ml at ITI start (P = .001), peak titres ≤100 BU/ml during ITI (P

Background: The appearance of inhibitors is the most serious complication in haemophilia A (HA) patients. The primary objective is their eradication. Up to date, immune tolerance induction (ITI) was the only therapeutic option to achieve this. Aim: To assess the efficacy of moroctocog-alpha as an ITI regimen in a population of HA patients with high-titre inhibitors. Methods: The REF.IT Registry is a retrospective-prospective study that collected data on all patients with HA and high-titre inhibitors treated with moroctocog-alpha as an ITI regimen at twelve Italian Haemophilia Centres. Results: We enrolled 27 patients, 85.2% were children. All patients were high responders, 88.9% had severe HA. We found 69.3% of them had one or more risk factors for poor ITI prognosis, 14.8% were ITI rescue. Overall 59.3% achieved a complete/partial success (complete in 51.9%). ITI failed in 11 patients, 63.6% of them with poor-prognosis risk factors. Inhibitors appeared after a mean of 27 exposure days. Mean historical peak was 78.8BU/mL. The primary ITIs started on average 20.2months after the diagnosis. A partial or complete success after a mean of 15months of treatment was achieved in 56.6% of the children while the same result was obtained by 75.0% adults after 22months from ITI onset. Patients who were treated with high-dose moroctocog-alpha (200UI/kg/day) were 63.0%. Conclusion: Our Registry showed that the use of moroctocog-alpha in the setting of ITI was effective and safe also in a population of patients with high-titre inhibitors, presenting one or more risk factors for poor ITI prognosis.
