Key Highlights from the Severe Asthma Pipeline Report

• Depemokimab (GSK), a long-acting anti–IL-5 monoclonal antibody for severe type 2 inflammatory asthma, has been accepted for FDA review, with a regulatory decision anticipated by December 16, 2025.
• In October 2025, Chiesi USA, Inc. (key-A-zee), a biopharmaceutical company that supports patients in living their best possible lives through life-changing or lifesaving innovations, today announced that the U.S. Food and Drug Administration has accepted the company’s New Drug Application (NDA) for its investigational maintenance treatment of asthma in adults. Chiesi’s inhaler delivers three active ingredients in a single device, referred to as a single inhaler triple therapy (SITT). Already approved in nearly 50 countries, this product is marketed outside of the U.S. under the brand name TRIMBOW®.
• In March 2025, AstraZeneca initiated a study to assess whether adolescents and adults receiving subcutaneous tezepelumab can safely reduce maintenance therapy while sustaining asthma control.
• Upstream Bio Inc. launched a clinical trial in March 2025 evaluating verekitug (UPB-101) for safety and efficacy in severe asthma, focusing on exacerbation frequency, lung function, asthma control, and tolerability versus placebo.
• In January 2025, AstraZeneca commenced a multicenter, randomized, open-label Phase IIIb trial to determine if patients treated with tezepelumab can taper maintenance therapy by Week 56 and achieve remission-like outcomes by Week 24.
• Also in January 2025, Upstream Bio initiated an additional study of verekitug (UPB-101) to further examine its pharmacodynamics, efficacy, safety, and tolerability in severe asthma patients.
• Incyte Corporation began a Phase II, double-blind, placebo-controlled, dose-ranging study in January 2025 to evaluate povorcitinib and its effects on pulmonary function in individuals with inadequately controlled moderate-to-severe asthma.
• DelveInsight reports that the severe asthma pipeline remains highly dynamic, with 40+ companies collectively advancing more than 50 investigational therapies.
• Major players include Kinaset Therapeutics, Bio-Thera Solutions, CSPC ZhongQi Pharmaceutical Technology, AB Science, GlaxoSmithKline, Oneness Biotech, Biosion, Lanier Biotherapeutics, Kymera Therapeutics, Suzhou Connect Biopharmaceuticals, Upstream Bio, Teva, and others.
• Prominent pipeline candidates include Verekitug (UPB-101), FB704A, TQC2731, Benralizumab, Povorcitinib, CM326, among several others.

Emerging Drugs in the Severe Asthma Pipeline

GSK3511294 (Depemokimab) – GlaxoSmithKline

Depemokimab is a long-acting monoclonal antibody targeting the interleukin-5 (IL-5) receptor, engineered for prolonged half-life and enhanced binding affinity compared with earlier IL-5 inhibitors. Developed by GlaxoSmithKline, the therapy is currently undergoing Phase III clinical evaluation for severe asthma management.

BSI-045B – Biosion

BSI-045B is a humanized, high-affinity monoclonal antibody targeting thymic stromal lymphopoietin (TSLP), a cytokine implicated in asthma and other Th2-mediated inflammatory diseases. Biosion’s partner CTTQ, which holds development and commercialization rights in China, is conducting a Phase II clinical trial of TQC2731 in patients with severe uncontrolled asthma.

Mepolizumab – Bio-Thera Solutions

Mepolizumab is a subcutaneously administered IL-5 antagonist monoclonal antibody, delivered via syringe or autoinjector. It is approved as an add-on maintenance therapy for several eosinophilic conditions, including severe eosinophilic asthma, chronic rhinosinusitis with nasal polyps, EGPA, and hypereosinophilic syndrome. Bio-Thera Solutions is currently evaluating mepolizumab in a Phase I study for severe asthma.
