SHANGHAI, Dec. 21, 2023 /PRNewswire/ -- Everest Medicines (HKEX 1952.HK, "Everest", or the "Company")'s licensing partner Calliditas Therapeutics AB (Nasdaq: CALT, Nasdaq Stockholm: CALTX) ("Calliditas") announced that the U.S. Food and Drug Administration (FDA) had approved Nefecon® delayed release capsules to reduce the loss of kidney function in adults with primary immunoglobulin A nephropathy (IgAN) at risk for disease progression. Nefecon® was first approved in December 2021 under the FDA accelerated approval pathway and is now the first fully FDA-approved treatment for IgAN based on a measure of kidney function.
"We congratulate our partner on the full FDA approval of Nefecon®, which confirms the drug's capability to preserve kidney function and significantly delay disease progression. This first-ever fully FDA-approved treatment for IgAN represents a beacon of hope for the entire IgAN community globally," said Rogers Yongqing Luo, Chief Executive Officer of Everest Medicines. "On the back of this important milestone, we are excited to be launching this first-in-disease treatment in China in the first quarter of 2024. China has the largest population of IgAN patients in the world with more rapid disease progression, and we are very happy to have the solution to address this urgent need."
"Nefecon® represents a revolutionary therapeutic option for Chinese patients who have more rapid disease progression in IgAN with no effective treatment options. This medicine offers patients a truly disease modifying treatment with sustained and clinically meaningful reduction in eGFR declines along with durable proteinuria reduction. The FDA full approval and the China approval allow physicians to take more proactive measures in managing the impact of the disease to preserve kidney function," said Professor Zhang Hong at Peking University First Hospital, a member of the global steering committee for the Phase 3 NefIgArd clinical trial. "Based on the exciting results in both efficacy and safety in the Chinese population observed from the NefIgArd trial, we believe Nefecon® will bring significant changes to Chinese patients with IgAN."
In the global Phase 3 trial, Nefecon® demonstrated a highly statistically significant and clinically relevant benefit compared to placebo in eGFR over the two-year period. The reduction in UPCR observed with Nefecon® treatment was also durable and the proportion of patients with microhematuria in the Nefecon group declined. Nefecon® was also generally well-tolerated in the Phase 3 clinical trial.
Further subpopulation analysis from the NefIgArd clinical trial showed a numerically greater treatment effect in kidney function prevention, proteinuria reduction and microhematuria improvement in the Chinese subpopulation compared to the global population. The mean absolute change from baseline in eGFR at 24 months showed approximately 66% less deterioration in kidney function with 9-month Nefecon® treatment compared with a smaller preservation of kidney function (50%) in the global population. Patients treated with Nefecon® in China showed a 43% greater reduction (95% CI 8%, 65%) in UPCR compared with placebo at 24 months and a 31% greater reduction (95% CI 0, 53) at 9 months. In the global population, Nefecon® treatment provided an approximately 30% greater reduction in UPCR at both 24 months and 9 months compared to placebo. The proportion of Chinese patients without microhematuria in the Nefecon® group increased from 26.9% at baseline to 57.7% during observational follow-up, while it was maintained at 14.3% in the placebo group.
About Nefecon®
Nefecon® is a patented oral, delayed release formulation of budesonide, a corticosteroid with potent glucocorticoid activity and weak mineralocorticoid activity that undergoes substantial first pass metabolism. The formulation is designed as a delayed release capsule that is enteric coated so that it remains intact until it releases budesonide to the distal ileum. Each capsule contains coated beads of budesonide that target mucosal B-cells present in the ileum where the disease originates, as per the predominant pathogenesis models.
In June 2019, Everest Medicines entered into an exclusive, royalty-bearing license agreement with Calliditas, which gives Everest Medicines exclusive rights to develop and commercialize Nefecon® in Mainland China, Hong Kong, Macau, Taiwan and Singapore. The agreement was extended in March 2022 to include South Korea as part of Everest Medicine's territories.
