Written in Blood predominant HL classification based on clinical data that indicate potential progression to Tcell histiocyte-rich large B-cell lymphoma and a more aggressive clinical course, therefore requiring different management. Other research has indicated that irrespective of myeloid or mesenchymal origin, some of these neoplasms are associated with or preceded by FL, CLL, B- or T-lymphocytic neoplasms, or PTCL. Histiocytic and Dendritic Cell Neoplasms REFERENCE Much of the 2008 classification is still accepted for histiocytic and dendritic cell neoplasms (HDCN), though Erheim-Chester disease (ECD) has been added as an entity.

[Epub ahead of print] EDITOR’S NOTE: The World Health Organiza- tion also revised its classification of myeloid neoplasms and acute leukemia, published in the April 11, 2016, edition of Blood. Look for our coverage of the revisions in “What To Call What We Treat, Part II: WHO Releases Updated Classification of Myeloid Neoplasms and Acute Leukemia” in our June issue. T:8.25” S:7” KOVALTRY [Antihemophilic Factor (Recombinant)] Lyophilized Powder for Solution f or Intravenous Injection – Reconstitution with Vial Adapter Initial U.S. Approval: 2016 BRIEF SUMMARY CONSULT PACKAGE INSERT FOR FULL PRESCRIBING INFORMATION 1 INDICATIONS AND USAGE KOVALTRY, Antihemophilic Factor (Recombinant), is a recombinant, human DNA sequence derived, full length Factor VIII concentrate indicated for use in adults and children with hemophilia A (congenital Factor VIII deficiency) for: • On-demand treatment and control of bleeding episodes • Perioperative management of bleeding • Routine prophylaxis to reduce the frequency of bleeding episodes KOVALTRY is not indicated for the treatment of von Willebrand disease. 4 CONTRAINDICATIONS KOVALTRY is contraindicated in patients who have a history of hypersensitivity reactions to the active substance, to any of the excipients, or to mouse or hamster proteins [see Description (11)]. 5 WARNINGS AND PRECAUTIONS 5.1 Hypersensitivity Reactions Hypersensitivity reactions, including anaphylaxis, are possible with KOVALTRY. Early signs of hypersensitivity reactions, which can progress to anaphylaxis, may include chest or throat tightness, dizziness, mild hypotension and nausea. Discontinue KOVALTRY if symptoms occur and seek immediate emergency treatment. KOVALTRY may contain trace amounts of mouse and hamster proteins [see Description (11)]. Patients treated with this product may develop hypersensitivity to these non-human mammalian proteins. 5.2 Neutralizing Antibodies Neutralizing antibody (inhibitor) formation can occur following administration of KOVALTRY. Previously untreated patients (PUPs) are at greatest risk for inhibitor development with all Factor VIII products [see Adverse Reactions (6.1)]. Carefully monitor patients for the development of Factor VIII inhibitors, using appropriate clinical observations and laboratory tests. If expected plasma Factor VIII activity levels are not attained or if bleeding is not controlled as expected with administered dose, suspect the presence of an inhibitor (neutralizing antibody) [see Warnings and Precautions (5.5)]. 5.3 Cardiovascular Risk Factors Hemophilic patients with cardiovascular risk factors or diseases may be at the same risk to develop cardiovascular events as non-hemophilic patients when clotting has been normalized by treatment with Factor VIII. 5.4 Catheter-related Infections Catheter-related infections may be observed when KOVALTRY is administered via central venous access devices (CVADs). These infections have not been associated with the product itself. 5.5 Monitoring Laboratory Tests • Monitor plasma Factor VIII activity levels using a validated test to confirm that adequate Factor VIII levels have been achieved and maintained [see Dosage and Administration (2.1)]. • M onitor for development of Factor VIII inhibitors. Perform a Bethesda inhibitor assay if expected Factor VIII plasma levels are not attained or if bleeding is not controlled with the expected dose of KOVALTRY. Use Bethesda Units (BU) to report inhibitor titers. 6 ADVERSE REACTIONS The most frequently reported adverse reactions in clinical trials (≥3%) were headache, pyrexia, and pruritus (see Table 3). 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates observed in clinical practice. The safety profile of KOVALTRY was evaluated in 193 previously treated patients (PTPs) (inclusive of 51 pediatric patients <12 years of age) with at least three months of exposure to KOVALTRY. The safety analysis was done using a pooled database from three multi-center, prospective, open-label clinical studies. The median time on study for patients ≥12 years of age was 372 days with a median of 159 exposure days (EDs). The median time on study for patients <12 years of age was 182 days with a median of 73 EDs. Subjects who received KOVALTRY for perioperative management (n=5) with treatment period of 2 to 3 weeks and those who received single doses of KOVALTRY for PK studies (n=6) were excluded from safety analysis. Table 3 lists the adverse reactions reported during clinical studies. The frequency, type, and severity of adverse reactions in children are similar to those in adults.
