CSL Behring announced FDA approval for a 50mL prefilled syringe of Hizentra (Immune Globulin Subcutaneous [Human] 20% Liquid) on April 18, 2023. Hizentra is the first immune globulin available in prefilled syringes, offering convenience for patients with Primary Immunodeficiency (PI) and Chronic Inflammatory Demyelinating Polyneuropathy (CIDP). The new size expands options for self-administration, decreasing treatment burden. Hizentra remains the most prescribed treatment for PI in the U.S. and is the only one approved for CIDP. Available in early 2024, the new syringe size joins existing 5mL, 10mL, and 20mL versions. CSL Behring aims to meet the anticipated demand for this innovative delivery method.

Tavneos^® has been newly incorporated in the 2022 EULAR recommendations for managing ANCA-associated vasculitis (AAV), according to a recent announcement by Vifor Fresenius Medical Care Renal Pharma. The recommendations highlight Tavneos^® as a key therapy option, emphasizing its ability to reduce glucocorticoid exposure and lower toxic effects while potentially enhancing renal function in GPA/MPA patients. The ADVOCATE study demonstrated that the Tavneos^® regimen surpassed prednisone in achieving sustained remission. This endorsement marks a significant step in enhancing patient care standards for AAV treatment, reflecting a commitment to reducing reliance on glucocorticoids.

CSL has announced significant results from the Phase 3 VANGUARD study, published in The Lancet, demonstrating the efficacy of garadacimab (CSL312) as a once-monthly prophylactic treatment for hereditary angioedema (HAE). The study involved 39 patients treated with garadacimab, showing an 86.5% reduction in the monthly attack rate compared to placebo. Early protection was evident, with 75% of patients attack-free within 3 months. The safety profile was favorable, with common adverse events including upper respiratory infection. Regulatory submissions for garadacimab are anticipated later this year, reflecting CSL's commitment to innovative treatments for patients with HAE.

CSL (ASX:CSL; USOTC:CSLLY) presented pivotal Phase 3 VANGUARD trial results for garadacimab, a novel monoclonal antibody aimed at preventing attacks in patients with hereditary angioedema (HAE). During the six-month trial, 61.5% of patients on garadacimab experienced no attacks, while those on placebo had none. The monthly dosage led to an 86.5% mean attack rate reduction (p<0.001). Safety data indicated no treatment discontinuations due to adverse events. CSL plans regulatory submissions for garadacimab later this year, further signaling its commitment to developing innovative treatments for rare diseases.

CSL announced pivotal HOPE-B trial results for HEMGENIX® (etranacogene dezaparvovec-drlb), the first gene therapy approved for adult hemophilia B patients, showing significant long-term efficacy and safety.
