Material Changes and Regulatory Approval
- New Indication: Nucala is now approved in China as an add-on therapy with intranasal corticosteroids for adults with inadequately controlled CRSwNP.
- Market Position: Mepolizumab is the only anti-interleukin-5 (IL-5) therapy approved in China for this specific indication.
- Portfolio Expansion: This represents the third indication for mepolizumab in China for an IL-5 mediated condition, following approvals for severe eosinophilic asthma and eosinophilic granulomatosis with polyangiitis.
- Target Population: Approximately 30 million people in China live with CRSwNP, experiencing symptoms such as sleep disturbance, breathing problems, and loss of smell.
Clinical Data and Management Commentary
The approval is based on the Phase III MERIT trial, a 52-week study involving Japanese, Chinese, and Russian patients. Key findings include:
- Efficacy: Mepolizumab significantly improved nasal obstruction scores (mean treatment difference: -1.43; p=0.003) and quality of life (SNOT-22 difference: -10.63; p=0.01) compared to placebo.
- Safety: The safety profile was consistent with known data, with 81% of mepolizumab patients and 76% of placebo patients experiencing on-treatment adverse events. No severe treatment-related adverse events were reported.
- Management View: Kaivan Khavandi, SVP of Global Head of Respiratory/Immunology R&D, stated the approval provides a non-surgical option and an alternative to repeated oral corticosteroid exposure for patients with this chronic condition.
