European Hematology Association Annual Congress June 13 – 16, 2019 Amsterdam, The Netherlands The 24th Annual Congress covers every subspecialty in hematology, with experts from around the world sharing original data and discussing the latest evidence-based approaches to treating hematologic disorders. International Conference on Malignant Lymphoma June 18 – 22, 2019 Lugano, Switzerland At the 15th International Conference on Malignant Lymphoma, the scientific community involved in the study and treatment of lymphoid neoplasms present the latest basic and translational science in the field. International Society on Thrombosis and Haemostasis’ Congress and Annual Scientific and Standardization Committee Meeting July 6 – 10, 2019 Melbourne, Australia The International Society on Thrombosis and Haemostasis’ 2019 Congress, a global meeting in thrombosis, hemostasis, and vascular biology, will be attended by thousands of the world’s experts. Amsterdam, The Netherlands Immunogenicity The development of factor VIII inhibitors with the use of ADVATE was evaluated in clinical trials with pediatric PTPs (<6 years of age with ≥50 factor VIII exposures) and PTPs (≥10 years of age with ≥150 factor VIII exposures). Of 276 subjects who were treated with ADVATE for at least 10 exposure days or on study for a minimum of 120 days, 1 adult developed a low-titer inhibitor (2 BU in the Bethesda assay) after 26 exposure days. Eight weeks later, the inhibitor was no longer detectable, and in vivo recovery was normal at 1 and 3 hours after infusion of another marketed recombinant factor VIII concentrate. This event results in a factor VIII inhibitor frequency in PTPs of 0.4% (95% CI of 0.01 and 2% for the risk of any factor VIII inhibitor development). No factor VIII inhibitors were detected in the 53 treated pediatric PTPs. USE IN SPECIFIC POPULATIONS In clinical trials that enrolled previously untreated subjects (defined as having had up to 3 exposures to a factor VIII product at the time of enrollment), 16 (29.1%) of 55 subjects who received ADVATE developed inhibitors to factor VIII. Seven subjects developed high titer (>5 BU) and nine subjects developed low-titer inhibitors. Inhibitors were detected at a median of 13 exposure days (min-max: 6−26 exposure days) to the product. Pediatric Use Pharmacokinetic studies in children have demonstrated higher clearance, a shorter half-life and lower recovery of factor VIII compared to adults. This may be explained by differences in body composition and should be taken into account when dosing or following factor VIII levels in the pediatric population. Because clearance (based on per kg body weight) has been demonstrated to be higher in the pediatric population, dose adjustment or more frequent dosing based on per kg body weight may be needed in this population. In the ADVATE routine prophylaxis clinical trial, 3 children aged 7 to <12 and 4 adolescents aged 12 to <16 were included in the per-protocol analysis. The reductions in annualized bleeding rate per subject per year during any prophylaxis regimen as compared to during on-demand therapy were similar among children, adolescents, and adults. Immunogenicity also was evaluated by measuring the development of antibodies to heterologous proteins. When assessed for anti-Chinese hamster ovary (CHO) cell protein antibodies, of 229 treated subjects, 3 showed an upward trend in antibody titer over time and 10 showed repeated but transient elevations of antibodies. When assessed for muIgG protein antibodies, of the 229 treated subjects, 10 showed an upward trend in anti-muIgG antibody titer over time and 2 showed repeated but transient elevations of antibodies. Four subjects who demonstrated antibody elevations to CHO cell or muIgG proteins, reported isolated events of urticaria, pruritus, rash, and slightly elevated eosinophil counts. All of these subjects had numerous repeat exposures to the product without recurrence of the events and a causal relationship between the antibody findings and these clinical events has not been established. Pregnancy Pregnancy Category C. Animal reproduction studies have not been conducted with ADVATE. It is not known whether ADVATE can cause fetal harm when administered to a pregnant woman or whether it can affect reproductive capacity. ADVATE should be given to a pregnant woman only if clearly needed. Nursing Mothers It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when ADVATE is administered to a nursing woman. Geriatric Use Clinical trials of ADVATE did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently compared to younger subjects. Individualize dose selection for geriatric patients. Chicago, IL ASH Meeting on Hematologic Malignancies September 6 – 7, 2019 Chicago, IL Top experts in hematologic malignancies discuss the latest developments in clinical care and provide answers to challenging patient care questions in a small-group setting. The program content is structured as “How I Treat” presenta- tions, which showcase each speaker’s evidence- based treatment approach. 2019 ASTRO Annual Meeting September 15 – 18, 2019 Chicago, IL The annual meeting of the American Society for Radiation Oncology provides a forum for more than 11,000 attendees to discuss the translation of scientific discoveries into clinical applications and opportunities for cure. When assessed for the presence of anti-human von Willebrand Factor (VWF) antibodies, of the 228 treated subjects, none displayed laboratory evidence indicative of a positive serologic response. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to ADVATE with the incidence of antibodies to other products may be misleading. Post-Marketing Experience The following adverse reactions have been identified during post-approval use of ADVATE. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Table 2 represents the most frequently reported post-marketing adverse reactions as MedDRA Preferred Terms.
