[{"type":"text","content":"– IONIS-FB-LRx achieved a 44% mean reduction in proteinuria in patients treated for 6 months\n– Roche to advance IONIS-FB-LRx into Phase 3 development in H1 2023\nCARLSBAD, Calif., Nov. 7, 2022 /PRNewswire/ -- Ionis Pharmaceuticals, Inc. (Nasdaq: IONS) today presented positive results from a Phase 2 clinical study of IONIS-FB-LRx in patients with immunoglobulin A nephropathy (IgAN). Results from the study were presented in a poster session at the American Society of Nephrology's (ASN) Kidney Week 2022.\n\n \n \n \n \n \n \n\n \nIn the Phase 2 study, IONIS-FB-LRx met its primary endpoint of change in 24-hour urinary protein, demonstrating a 44% mean reduction in proteinuria from baseline to week 29. Kidney function, as measured by estimated glomerular filtration rate (eGFR), was maintained in all patients in the study. IONIS-FB-LRx achieved robust and sustained reductions in plasma complement Factor B (CFB), Alternative Pathway Activity (AH50), and urinary complement fragment Ba (Factor Ba). IONIS-FB-LRx also demonstrated a favorable safety and tolerability profile in this study.\n\"We are extremely pleased with the results from this proof-of-concept Phase 2 study of IONIS-FB-LRx, which demonstrated the potential to treat IgAN by inhibiting complement Factor B,\" said Richard Geary, Ph.D., executive vice president, drug development, at Ionis. \"IgAN can lead to chronic kidney disease and kidney failure and has few treatment options. Given the significant unmet medical need, we are particularly pleased that Roche is moving expeditiously to advance IONIS-FB-LRx into Phase 3 development for IgAN in the first half of next year.\"\nAbout the IONIS-FB-LRx StudyIONIS-FB-LRx is being evaluated in an ongoing open-label, single arm, Phase 2 clinical study in up to 25 participants with IgAN in two dose cohorts treated sequentially (NCT04014335). The first dose cohort included 10 patients treated for 29 weeks. The primary endpoint in the study is the change in 24-hour urine protein excretion from baseline to week 29. The study is also evaluating reduction in plasma complement Factor B, measures of kidney function and safety and tolerability of monthly dosing of IONIS-FB-LRx.\nAbout IgA Nephropathy (IgAN)Immunoglobulin A nephropathy (IgAN) is an important cause of chronic kidney disease and renal failure. Also known as Berger's disease, IgAN ...
