    Abstract: Abstract 115 Background: Treatment with lenalidomide in patients with low risk MDS with deletion del(5q) has resulted in a high proportion of transfusion independence and also cytogenetic responses. The aim of this study was to evaluate the effect of lenalidomide in high risk MDS and AML patients with del(5q) or monosomy 5 not eligible for induction treatment, primary cases as well as patients relapsing/refractory to intensive treatment. Methods: This investigator-initiated prospective phase II study assessed the effects of continuous lenalidomide treatment during 16 weeks, in increasing doses from 10 to 30 mg, with 8 weeks on the highest level. Dose modifications due to hematologic toxicity were performed according to the clinical judgment of the treating physician. The primary objective was cytogenetic response, assessed by FISH on bone marrow (BM) smears at inclusion and after 8 and 16 weeks. Clinical and morphological BM response was evaluated every 4 weeks. Results: 25 patients were included from October 2007 to July 2009, 22 of which are so far evaluable. Overall, the patient cohort included several patients with very advanced disease and two patients died before treatment was started. Fourteen MDS patients and 11 AML patients have been included. Twenty-two of the patients had 5q- (9 of these had a complex karyotype and 5 had del(5q)+1) and 3 patients had monosomy 5 (all complex karyotype). The median time of treatment was 13 weeks (range 0–16 weeks). The reason for early termination in the patients who started lenalidomide treatment was progressive disease (3) and adverse events (10). Six of 7 patients who completed the study (16 weeks of treatment) had a response: Two MDS patients with del(5q-)+1, and del(5q)+2, respectively, achieved a major cytogenetic response (≥50 % reduction), in one of these patients the blast count decreased from 9.5% to 〈 5%. Two MDS patients with 5q- and complex karyotype had a minor cytogenetic response (≥25% reduction) and a reduction to 〈 5% blasts, respectively. One AML with 5q- and a complex karyotype had a minor cytogenetic response and a complete BM response. Another AML patient with isolated 5q- showed a complete BM, but no cytogenetic response. In total, 6 of the 20 patients (30%) who started treatment had a cytogenetic and/or morphological BM response. Four of 6 responders also experienced hematologic response. Twenty-one serious adverse events (SAE) have been reported in 15 of the patients. The main SAE criterion has been inpatient hospitalization. Fourteen of the SAE:s were infection or febrile neutropenia. In 6 patients the outcome of the SAE has been death. For these patients the causality/relationship to lenalidomide has been judged as not suspected or not related. The cause of death has been the underlying disease or complications to the underlying disease like infections. Conclusion: Lenalidomide as a single agent, but in higher doses than those applied to low-risk MDS patients resulted in cytogenetic and/or morphological bone marrow response in 30% of patients with high-risk MDS or AML with del(5q) or monosomy 5. We considered this a promising response rate, considering the high frequency of very advanced patients, and complex karyotypes. The main serious adverse event was infections. Future combinations with cytostatic or hypometylating agents may further improve these results. Disclosures: Möllgård: Celgene: Research Funding. Hellström-Lindberg:Celgene: Research Funding.

    Abstract: Recent advances in therapeutics are now providing a wide range of options for adults and children living with hemophilia. Although therapeutic choices are also increasing for the youngest individuals with severe disease, challenges remain about early management decisions, as supporting data are currently limited. Parents and healthcare professionals are tasked with helping children achieve an inclusive quality of life and maintain good joint health into adulthood. Primary prophylaxis is the gold standard to optimize outcomes and is recommended to start before 2 years of age. A range of topics need to be discussed with parents to aid their understanding of the decisions they can make and how these will affect the management of their child/children. For those with a family history of hemophilia, prenatal considerations include the possibility of genetic counseling, prenatal investigations, and planning for delivery, together with monitoring of the mother and neonate, as well as diagnosis of the newborn and treatment of any birth-associated bleeding. Subsequent considerations, which are also applicable to families where infant bleeding has resulted in a new diagnosis of sporadic hemophilia, involve explaining bleed recognition and treatment options, practical aspects of initiating/continuing prophylaxis, dealing with bleeds, and ongoing aspects of treatment, including possible inhibitor development. Over time, optimizing treatment efficacy, in which individualizing therapy around activities can play a role, and long-term considerations, including retaining joint health and tolerance maintenance, become increasingly important. The evolving treatment landscape is creating a need for continually updated guidance. Multidisciplinary teams and peers from patient organizations can help provide relevant information. Easily accessible, multidisciplinary comprehensive care remains a foundation to care. Equipping parents early with the knowledge to facilitate truly informed decision-making will help achieve the best possible longer-term health equity and quality of life for the child and family living with hemophilia. Plain language summary Points to be taken into account to help families make decisions to best care for children born with hemophilia Medical advances are providing a range of treatment options for adults and children with hemophilia. There is, however, relatively limited information about managing newborns with the condition. Doctors and nurses can help parents to understand the choices for infants born with hemophilia. We describe the various points doctors and nurses should ideally discuss with families to enable informed decision-making. We focus on infants who require early treatment to prevent spontaneous or traumatic bleeding (prophylaxis), which is recommended to start before 2 years of age. Families with a history of hemophilia may benefit from discussions before pregnancy, including how an affected child would be treated to protect against bleeds. When mothers are pregnant, doctors can explain investigations that can provide information about their unborn child, plan for the birth, and monitor mother and baby to minimize bleed risks at delivery. Testing will confirm whether the baby is affected by hemophilia. Not all infants with hemophilia will be born to families with a history of the condition. Identification of hemophilia for the first time in a family (which is ‘sporadic hemophilia’) occurs in previously undiagnosed infants who have bleeds requiring medical advice and possibly hospital treatment. Before any mothers and babies with hemophilia are discharged from hospital, doctors and nurses will explain to parents how to recognize bleeding and available treatment options can be discussed. Over time, ongoing discussions will help parents to make informed treatment decisions: • When and how to start, then continue, prophylaxis. • How to deal with bleeds (reinforcing previous discussions about bleed recognition and treatment) and other ongoing aspects of treatment.  ○ For instance, children may develop neutralizing antibodies (inhibitors) to treatment they are receiving, requiring a change to the planned approach. • Ensuring treatment remains effective as their child grows, considering the varied needs and activities of their child.

    Abstract: The 6 th Haemophilia Global Summit was held in Prague, Czech Republic, in September 2015. The programme was designed by an independent Scientific Steering Committee of haemophilia experts and aimed to share optimal management strategies for haemophilia at all life stages, explore recent potential advances in the management of haemophilia A and B and discuss challenges in haemophilia care. In this supplement from the meeting, Dan Hart reviews the lessons that can be learnt from cost‐constrained environments with regard to improving care for people with haemophilia globally. Sébastien Lobet discusses the importance of physical activity for optimising care and Roseline d'Oiron and Jan Blatný consider the role of real‐world data in understanding the effect of treatment in a clinical setting over the long term and the true impact of treatment on the day‐to‐day life of the patient. Gili Kenet addresses the current challenges relating to the optimal management of prophylaxis, and Gerry Dolan and Cedric Hermans discuss the value of pharmacokinetic (PK) parameters in informing treatment decisions. Cedric Hermans and Valérie Libotte explore the importance of considering social and occupational development factors as an integral part of haemophilia care, and Jan Astermark reviews key strategies to predict and prevent inhibitor development.

    Abstract: The development of inhibitory antibodies to factor VIII ( FVIII ) or factor IX ( FIX ) in patients with haemophilia is a serious complication of treatment with coagulation factor concentrates. Antibodies develop in 10–15% of haemophilia A and in up to 5% of haemophilia B patients. Several strategies have been developed over the years to facilitate the eradication of inhibitors and reduce the cost. These include plasmapheresis and/or extracorporeal protein A absorption to remove the inhibitor from the plasma, and immunosuppression and/or immune modulation to suppress the production of inhibitory antibodies. Different immunosuppressive ( IS ) agents have been described with varying success. To evaluate the outcome of these agents, we performed a systematic literature review using the P ubMed database. The total number of articles identified was 345; 299 papers were excluded leaving 46 papers to be included in the study. No randomised studies were identified, only case reports and case series. The most frequently used agents in the 46 case reports and cohort studies identified were cyclophosphamide and rituximab. All cases exposed to cyclophosphamide, rituximab and other IS agents had a complete success rate of 40–44%, 40–63% and 33–56%, respectively. However, the definition of success was not consistent among the studies. In conclusion, our review of the literature indicates that IS agents in combination with FVIII or FIX could be an option and may be cost‐effective in many patients. The risk of adverse events seems to be relatively low. To fully explore the effect of IS agents, randomised studies are warranted.

    Abstract: The greatest barrier to successful haemophilia A care in resource‐rich countries is the development of inhibitors to therapeutic factor VIII . Children with inhibitors suffer through increased bleeding and joint damage as well as frequent venepuncture. Costs associated with inhibitors are beyond many healthcare systems. Over the last two decades, there has been no improvement in our ability to reduce inhibitor development. Current strategies based on early prophylaxis and avoidance of immunological danger signals have given rise to conflicting results. Registry data suggest an increasing problem. Our understanding of the immunological systems involved in inhibitor formation should inform efforts to prevent inhibitors. Great efforts with mouse models are being undertaken in this field. However, there is no guarantee of the availability of any new agents arising from experimental work in the near future. Global immunomodulatory agents may be one solution. Compounds with a long history of use in inflammatory conditions have demonstrated efficacy in preventing antibodies to protein therapeutics both in animal models and in humans. As these compounds have a long history of use in humans, including babies, it may be that these agents offer an option for reducing inhibitor formation in previously untreated patients.

    Abstract: Treatment optimization in haemophilia A can be achieved by choice of FVIII product and knowledge of pharmacokinetics (PK), phenotype and adherence. A favourable PK profile of BAY 81–8973 (octocog alfa) (Kovaltry, Bayer AB) compared to other standard half‐life (SHL) FVIII products has been suggested. Aim To evaluate whether the switch to BAY 81–8973, using the same dosing schedule, impact factor consumption and bleed rates, taking arthropathy and adherence into account Methods Forty patients on prophylaxis with SHL (median age 40.5 years) attending the haemophilia treatment centres in Malmö and Oslo were enrolled. The annualised bleeding rate (ABR) and joint bleeding rate (AJBR) before and after the switch to BAY 81–8973 was calculated. PK analyses were performed with WAPPS‐Hemo. Joint health status and treatment adherence were assessed. Results The median ABR and AJBR was 0 before and after the switch, at both centres. The median yearly factor consumption was 3,345 IU/Kg/year in the entire study group corresponding to intermediate‐intensity prophylaxis in most patients and with significantly more used in Malmö (3,862 IU/Kg/year), compared to Oslo (2,337 IU/Kg/year) ( P .006). There was no correlation between arthropathy and bleeding. The median BAY 81–8973 t½ was 15.15 h (range 7.5–29 h), with significant correlation to VWF levels, and 13.4 h after exclusion of VWF outliers. Adherence to treatment was 97%. Conclusions Concentrate switch, using mainly intermediate‐intensity regimens with high adherence rates, preserves excellent prophylaxis outcome using standard half‐life FVIII products, indicating the value of individualized prophylaxis and close follow‐up.

    Abstract: Perioperative dosing recommendations vary across Nordic haemophilia treatment centres (HTCs) for extended half‐life (EHL) factor concentrates in haemophilia A/B (HA/HB) patients. Aim To summarise Nordic real‐world surgical experiences with EHL recombinant factor VIII/IX Fc (rFVIIIFc/rFIXFc) fusion proteins using retrospective data from clinical records at four HTCs in Finland, Sweden and Norway. Methods Factor dosing and surgical outcomes were recorded from HA/HB patients who underwent surgery and were treated with rFVIIIFc/rFIXFc. Perioperative factor dosing regimens were clinician‐determined based on local practises. Results Twenty five surgeries were performed on 20 patients, all covered by bolus injections except one minor HA surgery; eight minor surgeries were in paediatric patients. Median preoperative rFVIIIFc dose for major HA surgeries ( n  = 8) was 48 IU/kg (range: 35–57), with total consumption up to Day 14 of 427 IU/kg (196–568). For the two major HB surgeries (in one patient), preoperative rFIXFc doses were 50 IU/kg and 20 IU/kg; total consumption up to Day 14 was 130 IU/kg and 40 IU/kg. Median preoperative rFVIIIFc/rFIXFc bolus doses for minor HA ( n  = 10) and HB ( n  = 4) surgeries were 50 IU/kg (24–79) and 47 IU/kg (40–71), with total consumption up to Day 5 of 138 IU/kg (49–404) and 100 IU/kg (43–125), respectively. Intraoperative and postoperative haemostatic responses were rated as at least good/excellent for 24/25 surgeries, with bleeding episodes reported in only three surgeries. Conclusion Nordic real‐world experiences suggest that EHL products can be used safely and effectively for peri‐operative haemostasis. Further research is required to develop local dosing guidelines for optimised treatment schedules.
