In a significant development for respiratory healthcare in the United Kingdom, the National Institute for Health and Care Excellence (NICE) has expanded its recommendations for GlaxoSmithKline’s (GSK) Nucala (mepolizumab). Following its established endorsement for severe eosinophilic asthma, Nucala is now also recommended by NICE for adult patients suffering from chronic obstructive pulmonary disease (COPD) who experience uncontrolled symptoms and exhibit elevated blood eosinophil counts. This dual recommendation marks a pivotal moment, broadening the clinical utility of this advanced biologic therapy and enhancing its accessibility within the UK’s National Health Service (NHS).
The updated guidance from NICE, particularly the draft recommendations concerning COPD, signifies a crucial step forward in addressing the complex and often debilitating nature of this progressive lung disease. For patients with COPD, particularly those whose condition is characterized by eosinophilic inflammation, Nucala will now be available as an add-on maintenance therapy. This will be administered alongside the current standard of care (SoC) for COPD, which typically involves triple inhaled therapy. The inclusion of Nucala in this treatment paradigm offers a new therapeutic avenue for individuals who have not achieved adequate symptom control or experienced sufficient reduction in exacerbations with conventional treatments.
The decision by NICE to recommend Nucala for COPD is underpinned by robust clinical evidence derived from pivotal studies, including the MATINEE (NCT04133909), METREX (NCT02105948), and METREO (NCT02105961) trials. These comprehensive clinical investigations demonstrated that Nucala, when used as an adjunct to SoC, was effective in reducing the frequency of COPD exacerbations. Specifically, the studies indicated a reduction in yearly exacerbations by up to 21% compared to placebo and SoC. Furthermore, Nucala significantly prolonged the time to a patient’s first exacerbation, a critical outcome for managing the disease’s trajectory and preventing potentially life-threatening events. The data from these trials provided a strong foundation for NICE to assess Nucala’s cost-effectiveness and clinical benefit in the COPD population.
Nucala’s journey to this expanded recommendation has been one of progressive clinical validation. Initially, Nucala, a monoclonal antibody targeting the interleukin-5 (IL-5) pathway, received its first NICE recommendation in 2016 for the treatment of severe eosinophilic asthma. This early endorsement established its efficacy in managing inflammatory respiratory conditions driven by eosinophils. The subcutaneous administration, typically on a four-weekly schedule, offers a convenient dosing regimen. Importantly, patients can be trained to self-inject the medication, empowering them with greater control over their treatment and potentially improving adherence. This established track record in asthma likely played a role in the positive evaluation for its use in COPD, given the shared underlying inflammatory mechanisms in certain patient subgroups.
The implications of NICE’s broadened recommendation extend beyond individual patient care. Professor Richard Russell, a distinguished Professor of Respiratory Medicine at King’s College London, highlighted the dual benefits of this development. He articulated that Nucala’s expanded use within the NHS has the potential to not only significantly improve patient outcomes by reducing exacerbations and enhancing quality of life but also to alleviate pressure on the healthcare system. By mitigating the need for frequent hospitalizations, which are often a consequence of severe COPD exacerbations, Nucala could contribute to substantial cost savings and improved resource allocation within the NHS. This perspective underscores the value of innovative therapies in addressing both clinical and economic challenges in healthcare.
The landscape of biologic treatments for COPD in the UK is evolving, and Nucala’s inclusion signifies a growing trend towards personalized medicine. It is noteworthy that Nucala is not the sole biologic therapy to receive recent positive consideration from NICE for COPD. In March 2026, NICE also issued final guidance endorsing the use of Sanofi’s Dupixent (dupilumab) for the same COPD patient population. This decision followed an earlier rejection of Dupixent in 2018, illustrating NICE’s iterative review process and its responsiveness to accumulating clinical data and evolving treatment guidelines. The concurrent approval of both Nucala and Dupixent for specific COPD subgroups suggests a maturing understanding of the heterogeneous nature of the disease and the role of targeted biologic interventions.
Fulfilling Unmet Needs in COPD Management
The positive reception of Nucala by NICE is being hailed as a significant milestone by patient advocacy groups. Sarah Sleet, CEO of Asthma + Lung UK, commented on the development, emphasizing its importance for the COPD community. However, she also brought to light the persistent challenges in COPD care, noting that fewer than 10% of patients with the condition receive what she termed "the basic care they need to stay well." This stark statistic underscores the significant unmet needs that persist despite advancements in treatment. Sleet further pointed out that eligibility for Nucala, like other targeted therapies, will be restricted to a subset of patients with uncontrolled COPD. This limitation highlights the ongoing necessity for continued research and development to identify and implement new treatment strategies that can benefit a broader spectrum of individuals living with COPD.
The future of COPD treatment is increasingly looking towards biologic and disease-modifying therapies. GlobalData’s Pharmaceutical Intelligence Center tracks the development pipeline for such treatments. Currently, there are eight biologic candidates in Phase III clinical trials for COPD, indicating a robust research effort aimed at addressing the unmet needs in this area. These investigational therapies target various pathways implicated in COPD pathogenesis, offering hope for improved management strategies.
Among these promising candidates is Amgen and AstraZeneca’s Tezspire (tezepelumab), a thymic stromal lymphopoietin (TSLP) blocker. Tezspire has advanced to Phase III trials for COPD, a significant step despite having missed its primary endpoint in a mid-stage study for the same indication. This progression demonstrates the industry’s commitment to exploring the therapeutic potential of TSLP inhibition in COPD, building on its success in other respiratory diseases like severe asthma.
GSK itself is actively working to build upon Nucala’s success with the development of an ultra-long-acting successor, Exdensur (depemokimab). Exdensur is another IL-5 inhibitor and secured US regulatory approval for severe asthma in 2025. GSK is currently evaluating its potential in the Phase III ENDURA program, suggesting a strategic focus on developing next-generation biologics for respiratory conditions with improved dosing profiles and potentially broader efficacy.
The economic outlook for the COPD market is also substantial. A report from GlobalData, the parent company of Pharmaceutical Technology, projects significant growth in the COPD market. Analysts anticipate that the global market value for COPD treatments will reach an impressive $30.2 billion by 2033. This projection underscores the immense commercial opportunity but also reflects the significant burden of the disease worldwide and the ongoing demand for effective interventions. The expansion of Nucala’s use by NICE in the UK is a step towards realizing better patient outcomes within this growing, yet challenging, therapeutic area.
Historical Context and Regulatory Milestones
The journey of Nucala from its initial approval for asthma to its expanded indication in COPD is a testament to the evolving understanding of respiratory diseases and the power of targeted biologic therapies.
- 2016: NICE first recommends Nucala (mepolizumab) for the treatment of severe eosinophilic asthma in the UK. This marked a significant step in introducing IL-5 blockade as a treatment option for a specific, high-unmet-need asthma population.
- 2018: NICE initially rejects Sanofi’s Dupixent (dupilumab) for the treatment of COPD. This decision likely reflected concerns regarding clinical effectiveness, cost-effectiveness, or the available data at the time.
- March 2026: NICE issues final guidance recommending Dupixent for use in the same COPD patient population for which Nucala is now recommended. This reversal highlights NICE’s dynamic review process and its consideration of new evidence.
- Recent Draft Guidance: NICE releases draft guidance recommending Nucala for adult patients with uncontrolled COPD characterized by raised blood eosinophils, to be used as an add-on maintenance therapy alongside standard triple inhaled therapy. This recommendation is based on data from the MATINEE, METREX, and METREO studies.
- Current Status: Nucala’s recommendation for COPD is being integrated into the NHS treatment protocols, expanding its clinical uptake and providing a new therapeutic option for eligible patients.
Supporting Data and Clinical Evidence
The clinical efficacy of Nucala in COPD has been demonstrated through rigorous trials:
