A prospective, multicenter, open-label phase III study of emicizumab prophylaxis in patients with acquired hemophilia A. J Thromb Haemost 2023; 21:534-545. [PMID: 36696195 DOI: 10.1016/j.jtha.2022.10.004] [Citation(s) in RCA: 27] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2022] [Revised: 09/09/2022] [Accepted: 10/05/2022] [Indexed: 01/26/2023]
Abstract
BACKGROUND Emicizumab is a bispecific antibody that mimics the cofactor function of activated factor (F) VIII. It prevents bleeds in patients with congenital hemophilia A regardless of the inhibitor status; however, no prospective clinical studies have been conducted for emicizumab in patients with acquired hemophilia A (PwAHA). OBJECTIVES To describe the primary analysis results from a prospective, multicenter, open-label phase III study evaluating the efficacy, safety, and pharmacokinetics of emicizumab in PwAHA (AGEHA; JapicCTI-205151). METHODS Emicizumab was administered subcutaneously at 6 mg/kg on day 1 and 3 mg/kg on day 2, followed by 1.5 mg/kg once weekly from day 8 onward. Predefined criteria for the completion of dosing included FVIII activity of >50 IU/dL. RESULTS By the cutoff date (April 23, 2021), 12 patients on immunosuppressive therapy were enrolled, and 11 of them (91.7%) completed emicizumab treatment. The mean trough plasma emicizumab concentration rapidly reached a steady state (1 week), achieving the efficacious level that was established in patients with congenital hemophilia A (>30 μg/mL). Before first emicizumab administration, 7 patients (58.3%) experienced 77 major bleeds. During emicizumab treatment, no major bleeds occurred in any patient. Neither death due to bleeding or infection nor any study treatment-related serious adverse event was reported. One asymptomatic, nonserious deep vein thrombosis was discovered with no laboratory findings indicating any trend toward hypercoagulation. CONCLUSION These results suggest that emicizumab prophylaxis with the tested dosing regimen and completion criteria may have a favorable benefit-risk profile in PwAHA.

Abstract
BACKGROUND Acquired hemophilia A (AHA) is a rare disorder, and clinical practices for treating AHA have not been fully clarified in Japan. OBJECTIVES This study aims to investigate the epidemiology of AHA and real-world treatment practices in Japan. PATIENTS/METHODS This observational study was based on a health administrative database of hospitalized patients diagnosed with AHA who were treated with immunosuppressants. RESULTS The study included 214 males and 124 females (mean age 75.7 years). The most frequently used bypassing agent was recombinant activated factor VII. The predominant choice of immunosuppressant for first-line treatment was steroid monotherapy. Median days from the index date to the start of rehabilitation was 65.0 for cardiovascular, 35.5 for respiratory and 23.0 for locomotor. The proportion of patients with an activities of daily living (ADL) score < 70 points was high at both first admission and final discharge (47.4% and 38.8%). The percentage of deaths during hospitalization was 18.6%. CONCLUSIONS This study clarified the treatment patterns and clinical outcomes of AHA in a large population in Japan. This was the first study showing ADL score distribution and time to rehabilitation. Further investigation is needed to develop better clinical practices for treatment of AHA.

Abstract
Background Perioperative bleeding and transfusion have been associated with major morbidity and mortality after cardiac surgery. As concerns remain regarding potential graft thrombosis following administration of a prothrombin factor concentrate, the use of factor eight inhibitor bypassing activity (FEIBA) in managing refractory postoperative bleeding has never been evaluated in patients undergoing isolated coronary artery bypass grafting (CABG). Objectives We aimed to examine the safety of FEIBA in patients undergoing isolated CABG, with respect to 30-day mortality, perioperative outcomes, and thrombotic complications. Methods A retrospective review was undertaken of all consecutive patients who had undergone isolated on-pump CABG between January 2015 and December 2019 at North Shore University Hospital. Patients requiring intraoperative extracorporeal membrane oxygenator support were excluded. Patients were divided into two groups, dependent upon whether they received FEIBA (n = 63) versus no FEIBA (n = 2493). A 1:5 propensity match analysis was employed, and patients were analyzed with respect to thrombotic complications, reintervention for myocardial ischemia, and short-term clinical outcomes. Results There was no difference in 30-day mortality between the two cohorts. There was also no significant difference in a composite of thrombotic complications (composed of deep vein thrombosis, pulmonary embolism, and stroke) between the two groups. Similarly, there was no significant difference in the requirement for postoperative reintervention for myocardial ischemia between patients who received FEIBA versus those who did not. Conclusions Factor eight inhibitor bypassing activity may be safe when used as rescue therapy for refractory bleeding following isolated CABG.

Abstract
BACKGROUND Perioperative bleeding and transfusion have been associated with adverse outcomes after cardiac surgery. The use of factor eight inhibiting bypass activity (FEIBA) in managing bleeding after repair of acute Stanford type A aortic dissection (ATAAD) has not previously been evaluated. We report our experience in utilizing FEIBA in ATAAD repair. STUDY DESIGN AND METHODS A retrospective review was undertaken of all consecutive patients who underwent repair of ATAAD between July 2014 and December 2019. Patients were divided into two groups, dependent upon whether or not they received FEIBA intraoperatively: "FEIBA" (n = 112) versus "no FEIBA" (n = 119). From this, 53 propensity-matched pairs of patients were analyzed with respect to transfusion requirements and short-term clinical outcomes. RESULTS Thirty-day mortality for the entire cohort was 11.7% (27 deaths), not significantly different between patient groups. Those patients who received FEIBA demonstrated reduced transfusion requirements for all types of blood products in the first 48 h after surgery as compared with the "no FEIBA" cases, including red blood cells, platelets, plasma, and cryoprecipitate (p < .0001). There was no significant difference in major postoperative morbidity between the two groups. The FEIBA cohort did not demonstrate an increased incidence of thrombotic complications (stroke, deep venous thrombosis, pulmonary thromboembolism). DISCUSSION When used as rescue therapy for refractory bleeding following repair of ATAAD, FEIBA appears to be effective in decreasing postoperative transfusion requirements whilst not negatively impacting clinical outcomes. These findings should prompt further investigation and validation via larger, multi-center, randomized trials.

Abstract
OBJECTIVE Activated prothrombin complex concentrate (aPCC) is a bypassing agent indicated to treat bleeds in patients with acquired hemophilia A (AHA). Nevertheless, its efficacy and safety in the real-world setting has not often been addressed. METHODS We report the experience of Spanish reference centers for coagulation disorders and from acquired haemophilia Spanish Registry (AHASR), from August 2012 to February 2021. Follow-up period of 30 days after aPCC withdrawal. RESULTS Thirty patients with a median age of 70 years old, suffering from 51 bleeds treated with aPCC were finally evaluated. As first line treatment, aPCC stopped bleed in 13 of 14 (92.9%) cases. aPCC as second line after recombinant factor VIIa failure, stopped bleeding in the all cases. In 17 patients aPCC was used far from initial bleed control as prophylaxis of rebleeding with 94% effectiveness. No thromboembolic episodes was communicated. One patient developed hypofibrinogenemia, which did not prevent aPCC from halting bleeding. No other serious adverse events possibly or probably associated with aPCC were reported. CONCLUSIONS this data support aPCC as haemostatic treatment in AHA with high effectiveness and excellent safety profile in acute bleeds and as extended use to prevent rebleedings, even in anging people with high cardiovascular risk.

Abstract
Immunosuppressive therapy (IST) is administered to patients with acquired hemophilia A (AHA) to eradicate autoantibodies against coagulation factor VIII (FVIII). Data from registries previously demonstrated that IST is often complicated by adverse events, in particular infections. This pilot study was set out to assess the feasibility of reduced-intensity, risk factor–stratified IST. We followed a single-center consecutive cohort of twenty-five patients with AHA receiving IST according to a new institutional treatment standard. Based on results from a previous study, GTH-AH 01/2020, patients were stratified into “poor risk” (FVIII < 1 IU/dl or inhibitor ≥ 20 Bethesda units (BU)/ml) or “good risk” (FVIII ≥ 1 IU/dl and inhibitor < 20 BU/ml). Outcomes were compared between the current cohort and the GTH registry as a historic control (n = 102). Baseline characteristics of the cohort were not different from the historic control. Partial remission, defined as FVIII recovered to > 50 IU/dl, was achieved by 68% of patients after a median time of 112 days, which was lower and significantly later than in the historic control (hazard ratio: 1.8, 95% confidence interval 1.2–2.8). Complete remission, overall survival, and frequency of fatal infections were not different. Grade 3 and 4 infections were more frequent. The impact of risk factors that was observed in the historic cohort was no longer apparent, as partial and complete remission and overall survival were similar in “good risk” and “poor risk” patients. In conclusion, reduced-intensity, risk factor–stratified IST is feasible in AHA but did not decrease the risk of infections and mortality in this cohort.

Abstract
Acquired hemophilia A (AHA), a rare bleeding disorder caused by neutralizing autoantibodies against coagulation factor VIII (FVIII), occurs in both men and women without a previous history of bleeding. Patients typically present with an isolated prolonged activated partial thromboplastin time due to FVIII deficiency. Neutralizing antibodies (inhibitors) are detected using the Nijmegen-modified Bethesda assay. Approximately 10% of patients do not present with bleeding and, therefore, a prolonged activated partial thromboplastin time should never be ignored prior to invasive procedures. Control of acute bleeding and prevention of injuries that may provoke bleeding are top priorities in patients with AHA. We recommend treatment with bypassing agents, including recombinant activated factor VII, activated prothrombin complex concentrate, or recombinant porcine FVIII in bleeding patients. Autoantibody eradication can be achieved with immunosuppressive therapy, including corticosteroids, cyclophosphamide and rituximab, or combinations thereof. The median time to remission is 5 weeks, with considerable interindividual variation. FVIII activity at presentation, inhibitor titer and autoantibody isotype are prognostic markers for remission and survival. Comparative clinical studies to support treatment recommendations for AHA do not exist; therefore, we provide practical consensus guidance based on recent registry findings and the authors' clinical experience in treating patients with AHA.

Abstract
Objectives: Acquired hemophilia A (AHA) is a rare disease resulting from autoantibodies against coagulation factor VIII that leads to spontaneous bleeding. This study reports the clinical characteristics and treatment outcomes of a relatively sizable cohort of patients with AHA. Methods: We retrospectively analyzed the characteristics and outcomes of 42 patients with AHA diagnosed in our center from January 2014 through December 2018. Results: The FVIII activity (FVIII: C) was significantly suppressed (median 1.5%; interquartile range [IQR]: 0.9-3.5) by FVIII inhibitor (median 8 BU/mL; IQR: 4.0-16.0). Bypassing agents, PCC or FVIIa, were used in 14 patients for bleeding control without any adverse reaction; and most patients (90.5%, 38/42) were placed on immunosuppressive regimen, corticosteroid alone or in combination with cyclophosphamide. Patients treated with corticosteroids alone had a lower median inhibitor titer (8 BU/mL) than those treated with combination corticosteroids of cyclophosphamide (16 BU/mL) (p < 0.001). 97.4% (37/38) patients achieved complete remission (CR) after immunosuppression therapy, and the median time to CR in patients treated with corticosteroids alone was shorter than those with combination corticosteroids of cyclophosphamide (median 40 days; IQR: 31-65 vs. 51 days; IQR: 38-83, p = 0.301). 10 (26.3%) patients relapsed thereafter and were placed on combined corticosteroid and cyclophosphamide treatment, which yielded second remission in 8 patients (80%). Two patients died, one from uncontrolled post-surgical retroperitoneal hemorrhage and one from sepsis complicating corticosteroid therapy. Conclusion: The corticosteroid achieves a satisfactory outcome, particularly with low inhibitors titers; and combination of cyclophosphamide will facilitate remission in sever patients with high titers of inhibitors.

Abstract
Acquired hemophilia A (AHA) is a rare acquired bleeding disorder caused by autoantibodies against autologous factor VIII (FVIII). It is a disease that most commonly affects the elderly, but it has been described in children and during the post-partum period. It is idiopathic in 50% of cases and is associated with autoimmune disease, malignancy, pregnancy, infection or certain medications in the other 50%. The diagnosis should be suspected in patients with an isolated prolonged aPPT without previous personal or familial bleeding history. Treating the bleeding and eradication of the inhibitor is the mainstay of treatment. The first line of treatment for acute bleeding is the use of bypassing agents. The most commonly used method for eradicating the inhibitor is immunosuppression, namely corticosteroids alone or in combination with cyclophosphamide. This review summarises current knowledge and reviews management options and guidelines.

Abstract
: In acquired haemophilia A (AHA), risk for recurrent bleeding exists until the inhibitor is detectable. Thus, patients with persisting inhibitor may benefit from prophylaxis with activated prothrombin complex concentrate (aPCC). Potential thromboembolic complications and cost are also factors to consider. Today, no high level evidence or clear recommendations are available on aPCC prophylaxis in AHA. Recently, a small prospective study demonstrated a favourable outcome with short-term, daily administered aPCC infusion. Here we report a retrospective case series of 19 patients with AHA to demonstrate our practice on aPCC prophylaxis. In our practice, clinical bleeding tendency guided our decision on the initiation of aPCC prophylaxis. In patients with serious bleeding tendency, aPCC infusion was prolonged beyond bleeding resolution in a twice-weekly or thrice-weekly regimen. Serious bleeding phenotype included a single episode of life-threatening bleeding or recurrent, severe haemorrhages. Patients who did not present such events were treated on-demand. The preventive dose of aPCC was equal with the lowest effective therapeutic dose. Prophylaxis was continued until the inhibitor disappeared. Eleven patients received aPCC prophylaxis. In nine cases, prophylaxis lasted beyond two months. No severe bleeding developed spontaneously and no thromboembolic complication occurred in the median 16 weeks (interquartile range 9-34) duration of prophylaxis. Eight patients of the nonprophylaxis group did not present any severe haemorrhage. According to our experience, we consider prophylaxis with aPCC effective and well tolerated for patients with AHA and serious bleeding tendency, until the acquired inhibitor persists.

Thromboembolic event rate in patients exposed to anti-inhibitor coagulant complex: a meta-analysis of 40-year published data. Blood Adv 2017; 1:2637-2642. [PMID: 29296916 DOI: 10.1182/bloodadvances.2017011536] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2017] [Accepted: 11/09/2017] [Indexed: 11/20/2022] Open
Abstract
Anti-inhibitor coagulant complex (AICC), an activated prothrombin complex concentrate, has been available for the treatment of patients with inhibitors since 1977, and thromboembolic events (TEEs) have been reported after infusion of AICC in patients with congenital or acquired hemophilia. With the aim of estimating the TEE incidence rate (IR) related to AICC exposure in these patients, a systematic review of the literature was carried out in Medline, according to PRISMA guidelines, from inception date to March 2017. The IR of TEEs was estimated through a meta-analytic approach by using a generalized linear mixed model based on a Poisson distribution. Thirty-nine studies were included (1980-2016). Overall, 46 TEEs were reported; of these, 13 were reported as disseminated intravascular coagulations, 11 as myocardial infarctions, and 3 as thrombotic cerebrovascular accidents. The pooled TEE IR was 2.87 (95% confidence interval [CI], 0.32-25.40) per 100 000 AICC infusions (5.42 in retrospective studies [95% CI, 0.92-31.82]; 1.09 in prospective studies [95% CI, 0.01-238.77]). The TEE rate was 5.09 (95% CI, 0.01-1795.60) per 100 000 AICC infusions administered on demand, whereas no TEEs were reported with prophylaxis. Interestingly, the estimated IR in patients with congenital hemophilia was <0.01 per 100 000 infusions. These findings provide robust evidence of safety of AICC over almost 40 years of published studies.
