Omalizumab

Amneal holds exclusive U.S. commercialization rights; BLA filing expected in Q4 2025 Poised to be among the first wave of biosimilars in the $3.9 billion U.S. omalizumab market and an important growth driver for Amneal June 25, 2025 -- Amneal Pharmaceuticals, Inc. (Nasdaq: AMRX) (“Amneal” or the “Company”) today highlighted positive topline results from a confirmatory clinical efficacy and safety clinical trial evaluating ADL-018, a proposed biosimilar to XOLAIR® (omalizumab), developed by Kashiv BioSciences, LLC. The randomized, double-blind, multicenter study was conducted by Kashiv to assess the efficacy, safety, and immunogenicity of ADL-018 compared to XOLAIR® in patients with Chronic Idiopathic Urticaria (CIU) or Chronic Spontaneous Urticaria (CSU) who remained symptomatic despite treatment with H1 antihistamines. Omalizumab, a humanized monoclonal antibody that targets free IgE, is indicated for the treatment of severe allergic asthma (>6 years old), chronic rhinosinusitis with nasal polyps (CRSwNP) (>18 years old), food allergies (>1 year old), and chronic spontaneous urticaria (>12 years old). It is typically administered in a hospital or clinic setting. The clinical study achieved its primary and secondary endpoints by establishing equivalence of therapeutic endpoints and comparable safety between ADL-018 and XOLAIR®. Participants received subcutaneous doses of either 150 mg or 300 mg every four weeks for a 24-week period. A total of 600 patients were enrolled, and efficacy and safety were evaluated in 400 patients who received the confirmatory dose of 300 mg. The primary efficacy measure was the change from baseline in the weekly itch severity score (ISS7) at Week 12 between the treatment arms of ADL-018 and the reference product. “We are pleased with the positive Phase 3 results for ADL-018, which represents an important step towards making a biosimilar to XOLAIR® available to U.S. patients,” said Sean McGowan, Senior Vice President, Biosimilars and Branded Oncology at Amneal Pharmaceuticals. “Pending FDA approval, we believe this will be a key addition to our biosimilars portfolio and part of our broader strategy to commercialize six biosimilars across eight product presentations by 2027.” “This marks a positive advancement for Kashiv’s growing biosimilar pipeline in addition to its current portfolio of RELEUKO® (filgrastim-ayow) and FYLNETRA® (pegfilgrastim-pbbk). We look forward to collaborating with regulatory authorities to make this treatment available to patients,” said Dr. Sandeep Athalye, Chief Executive Officer at Kashiv BioSciences. “Kashiv is among the few U.S.-based companies to both manufacture and receive marketing authorization for multiple biosimilars. We remain focused on delivering cost-effective, high-quality therapies to improve patient outcomes globally, working with commercial partners such as Amneal.” A Biologics License Application (BLA) for this product is expected to be submitted to the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2025 by Kashiv BioSciences. Amneal holds exclusive U.S. commercialization rights for the product, pending regulatory approval. According to IQVIA®, U.S. annual sales for XOLAIR® totaled approximately $3.9 billion for the 12 months ending April 2025. XOLAIR® is a registered trademark of Novartis AG.

June 25, 2025 — Alvotech (NASDAQ: ALVO), a global biotech company specializing in the development and manufacturing of biosimilar medicines for patients worldwide, Kashiv Biosciences LLC (“Kashiv”), a fully integrated biopharmaceutical company headquartered in New Jersey, US, and Advanz Pharma Holdco Limited (“Advanz Pharma”), a UK-headquartered global pharmaceutical company with a strategic focus on specialty, hospital, and rare disease medicines, today announced positive topline results from a confirmatory efficacy study comparing AVT23 (ADL-018), a proposed biosimilar to Xolair® (omalizumab), with the reference biologic. The randomized, double-blind, multicenter study assessed the efficacy, safety, and immunogenicity of AVT23 compared to Xolair® in patients with Chronic Spontaneous Urticaria (CSU), who remained symptomatic despite treatment with H1 antihistamines. The study met its primary endpoint, with data demonstrating equivalence of therapeutic endpoints and comparable safety between the biosimilar candidate and the reference biologic. Participants received subcutaneous doses of either 150 mg or 300 mg every four weeks over a 24-week period. A total of 600 patients were enrolled, and efficacy and safety were evaluated in 400 patients who received the confirmatory dose of 300 mg. The primary efficacy measure was the change from baseline in the weekly Itch Severity Score (ISS7) at Week 12 between the treatment groups of ADL-018 and reference product. “The positive results from this confirmatory patient study represent an important step in the development of the Xolair® biosimilar candidate. We look forward to working with our partners to increase global patient access to this important medicine,” said Joseph McClellan, Chief Scientific Officer of Alvotech. “This marks a positive advancement for Kashiv’s growing biosimilar pipeline in addition to its current portfolio of Releuko® and Fylnetra®. We look forward to collaborating with regulatory authorities to make this treatment available to patients,” said Dr. Sandeep Athalye, Chief Executive Officer at Kashiv BioSciences, “We remain focused on delivering cost-effective, high-quality therapies to improve patient outcomes globally, working with commercial partners such as Alvotech and Advanz Pharma.” “The successful confirmatory efficacy results for the proposed biosimilar to XOLAIR® mark an important milestone in Advanz Pharma’s ambition to expand patient access to specialty medicines across our core geographies, Europe, Canada, and Australia.” said Nick Warwick, Chief Medical Officer at Advanz Pharma. The UK Medicines and Healthcare Products Regulatory Agency (MHRA) has already validated and accepted the marketing authorization application (MAA) for AVT23 earlier this year, and the filing of an MAA with the European Medicines Agency (EMA) is expected before the end of the year. AVT23 is a proposed biosimilar to Xolair® (omalizumab). Omalizumab is a humanized monoclonal antibody that targets free immunoglobulin E (IgE). Xolair®, which contains omalizumab, is indicated for severe persistent allergic asthma, chronic rhinosinusitis with nasal polyps (CRSwNP), and IgE-mediated food allergy [1]. AVT23 is an investigational product and has not received regulatory approval in any country. Biosimilarity has not been established by regulatory authorities and is not claimed.
