Material Changes and Regulatory Developments
- China NMPA Approval: China's National Medical Products Administration (NMPA) approved Benlysta (belimumab) for the treatment of adult patients with active lupus nephritis (LN) receiving standard of care.
- Market Position: This approval makes belimumab the first and only biologic medicine approved in China for both systemic lupus erythematosus (SLE) and lupus nephritis.
- Global Context: Since December 2020, belimumab has been approved for active LN by 16 regulatory bodies globally, including the FDA and EMA. It is approved for SLE in 60 countries.
- Existing China Indications: Benlysta was previously approved in China for SLE in adults (July 2019) and children aged five and older (December 2020). It is included in China's 2021 National Reimbursement Drug List for paediatric SLE.
Clinical Data and Management Commentary
Clinical Evidence (BLISS-LN Trial): The approval is based on the BLISS-LN phase III trial, the largest and longest trial conducted in active LN involving 448 adult patients.
- Primary Endpoint: At 104 weeks, 43% of patients treated with belimumab plus standard of care achieved Primary Efficacy Renal Response (PERR) compared to 32% with placebo plus standard of care (Odds Ratio 1.55, p=0.0311).
- Secondary Endpoints: Statistical significance was achieved across all four major secondary endpoints, including complete renal response and time to renal-related event or death.
- Safety: Adverse reactions were consistent with the known safety profile of intravenous belimumab.
Management Commentary: Dr. Hal Barron, Chief Scientific Officer and President R&D, noted that nearly 500,000 people in China have SLE, with over half developing lupus nephritis. He stated this approval provides a new treatment option to help slow the progressive nature of the disease and preserve kidney function.
Risks and Contingencies
Safety Warnings:
- Hypersensitivity: Risk of severe or fatal infusion reactions and hypersensitivity, particularly with the first two doses.
- Infections: Increased risk of infections, including opportunistic and fatal infections (e.g., pneumonia, sepsis).
- Psychiatric: Risk of depression and suicidality; requires monitoring.
- Contraindications: Not studied in patients with severe active central nervous system lupus, hypogammaglobulinaemia, or history of major organ transplant.
Forward-Looking Statements: GSK cautions that projections are subject to risks and uncertainties, including those described in the 2020 Form 20-F, Q4 results, and impacts of the COVID-19 pandemic.
