CLINICAL NEWS Chemotherapy-Free Combination Shows Efficacy in Untreated Follicular Lymphoma The randomized, global, phase III RELEVANCE trial showed that a regimen of lenalidomide and rituximab (R 2 ) had similar safety and efficacy to a rituximab-based chemotherapy regimen (R-chemo) in patients with previously untreated follicular lymphoma (FL). This is the first randomized trial to demonstrate the efficacy of a chemother- apy-free regimen in this setting, lead au- thor Nathan Hale Fowler, MD, from the University of Texas MD Anderson Can- cer Center, noted during his presentation at the 2018 ASCO Annual Meeting. “For most patients with low-grade, grade 1-3a FL, rituximab plus chemo- therapy results in very good responses and prolonged progression-free survival (PFS),” Dr. Fowler noted. “However, most of these patients are still at risk of relapse and remissions are shorter with each subsequent line of therapy.” The RELEVANCE trial was designed as a superiority study evaluating R 2 and R-chemo in 1,030 patients with advanced, previously untreated FL. Participants were randomized 1:1 to receive: • R 2 : lenalidomide 20 mg/day plus rituximab 375 mg/m 2 (n=513) Interim results showed PFS was “nearly iden- tical” between the two arms, and in prespecified subgroup analyses this finding persisted regard- less of age, sex, disease stage, or FLIPI score. Almost all patients reported some treatment- emergent adverse events (99% in R 2 and 97% in T:7” S:6.75” EXPLORE THE COVERAGE OF KOVALTRY ® Dosing with KOVALTRY ® for routine prophylaxis in adults 1 : Individualize the patient’s dose based on clinical response • R-chemo (control arm): investigator choice of R-CHOP, R-bendamustine, or R-CVP (n=517) • 2-year PFS: 84% vs. 87% (hazard ratio = 1.10; 95% CI 0.85-1.43; p=0.48) ASHClinicalNews.org Regimen 20–40 IU/kg 2x/week or 3x/week LEOPOLD I trial: KOVALTRY ® PK results (arithmetic mean) 1 PK parameters were measured using chromogenic substrate assay after a single 50-IU/kg dose of KOVALTRY ® in 21 previously treated patients ≥18 years old The AUC was 2103.4 IU•h/dL The C max was 133.1 IU/dL The t 1/2 was 14.2 hours AUC=area under the curve.

See how KOVALTRY ® compared with Advate ® in a cross-over PK study INDICATIONS 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 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. SELECTED IMPORTANT SAFETY INFORMATION 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. 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. Please see additional Selected Important Safety Information on the following pages. For additional risk and use information, please see Brief Summary on following pages. • CR/CR unknown (CRu) at 120 weeks: 48% for R 2 vs. 53% for R-chemo (p=0.13) Dose In the R 2 arm, lenalidomide dose was lowered to 10 mg/day if patients achieved a complete response (CR). Participants in each arm received maintenance therapy with rituximab 375 mg/m 2 every eight weeks for up to one year. Baseline characteristics were “fairly well balanced” between both arms, Dr. Fowler said, with a similar incidence of bulky disease (42% and 38%), high- risk Follicular Lymphoma International Prognostic Index (FLIPI) score (49% and 48%), and B symptoms (27% and 26%). As of May 31, 2017 (data cutoff), more than half of patients in each cohort completed treatment: 69 percent in the R 2 cohort and 71 percent in the R-chemo cohort. After a median follow-up of 37.9 months (range not reported), superior- ity for the chemotherapy-free regimen over chemotherapy-containing regimens was not established for both co-primary endpoints: R-chemo). While the authors reported that the regimens were to lerable, with 8 percent and 3 percent discontinuing treatment due to toxicity, they noted that patients in the R-chemo arm ap- peared to experience more neutropenic events, including grade 3/4 neutropenia (160 [32%] and
