The self-injectable formulation of the antibody therapy Nucala is expected to be included in the insurance reimbursement system in Korea.According to Dailypharm coverage, GSK Korea has recently reached a final agreement on price negotiations with the National Health Insurance Service for the Nucala autoinjector (mepolizumab).This drug accepted the condition of “accepting a price below the evaluation amount” proposed by the Health Insurance Review and Assessment Service’s Drug Reimbursement Evaluation Committee in January and entered price negotiations in March.Since the Nucala Autoinjector has additional indications compared to the existing Nucala, its reimbursement listing process was conducted in a manner equivalent to that for a new drug. rather than a formulation addition.Nucala Autoinjector, which received domestic approval in March of last year, was launched as a non-reimbursed product in November of the same year after securing distribution channels and supply volume.It remains to be seen whether Nucala, which has established a foothold in the eosinophilic asthma market, will be able to expand its influence with the launch of this new formulation and successful reimbursement.The new autoinjector formulation has expanded its indications beyond the existing treatment of severe eosinophilic asthma in adults and adolescents (aged 12 and older) to include ▲ eosinophilic granulomatosis with polyangiitis (EGPA) in adults and ▲ hypereosinophilic syndrome (HES) in adults.This drug is a self-administered injectable used for the treatment of eosinophilic diseases. It is used as an add-on maintenance therapy for severe eosinophilic asthma (SEA) in adolescents and adults aged 12 years and older, as well as for eosinophilic granulomatosis with polyangiitis (EGPA) in adults and hypereosinophilic syndrome (HES) in adults (excluding FIP1L1-PDGFRα-positive patients).The autoinjector formulation allows patients to conveniently administer the drug themselves at home, featuring a self-administration success rate of over 96%, high patient preference, and ease of use.Meanwhile, Nucala is poised to enhance its competitiveness by securing an indication for chronic obstructive pulmonary disease (COPD). In May, the drug received additional approval from the U.S. FDA for ‘add-on maintenance therapy for adult patients with COPD with an eosinophilic phenotype.’This approval was based on the results of the Phase III MATINEE and METREX studies. In these studies, among a broad spectrum of COPD patients with an eosinophilic phenotype, the Nucala treatment group showed a significantly lower annual rate of moderate-to-severe exacerbations compared to the placebo group.
