Vertex Provides Updates on Multiple Kidney Programs at the American Society of Nephrology (ASN) Annual Kidney Week Congress
- New data on povetacicept 80 mg SC Q4 weeks in IgA nephropathy shows mean UPCR reduction from baseline of 66% observed at 48 weeks, associated with stable renal function (eGFR) and 63% achieving clinical remission --
- First proteinuria data on povetacicept in primary membranous nephropathy shows mean UPCR reduction from baseline of 62% at 24 weeks –
- Global Phase 3 RAINIER trial of povetacicept in IgA nephropathy now underway –
– Enrollment and dosing ongoing in Phase 3 portion of the global Phase 2/3 pivotal clinical trial of inaxaplin for the treatment of APOL1-mediated kidney disease –
BOSTON--(BUSINESS WIRE)-- Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today provided updates on multiple kidney diseases in its pipeline including IgA nephropathy (IgAN), primary membranous nephropathy (pMN), and APOL1-mediated kidney disease (AMKD). These updates demonstrate the transformative potential of Vertex’s investigational therapies in multiple serious kidney diseases, and include positive new data on povetacicept, a dual inhibitor of the BAFF and APRIL pathways, in IgAN and pMN, presented at the American Society of Nephrology’s (ASN) Kidney Week Congress on October 23-27 in San Diego, California.
“We are very pleased with the broadening of our innovative pipeline in renal medicine which now spans programs in AMKD, IgAN, pMN and polycystic kidney disease,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex. “The new data in IgAN and pMN we shared at this year’s ASN congress continue to reinforce povetacicept as a potential best-in-class therapy and demonstrate its potential as a pipeline-in-a-product. We also continue to make progress in AMKD and autosomal dominant polycystic kidney disease (ADPKD) where we are advancing the first potential treatments to address the underlying cause of these diseases.”
Povetacicept in IgAN
Vertex presented data on 54 patients with IgAN who received povetacicept 80 mg or 240 mg subcutaneously every 4 weeks (SC Q4W). Treatment with povetacicept 80 mg SC Q4W demonstrated a clinically meaningful decrease in proteinuria, with a mean 66% reduction from baseline in urine protein to creatinine ratio at 48 weeks (UPCR; n=8) associated with stable renal function over 48 weeks as assessed by estimated glomerular filtration rate (eGFR). By 48 weeks, 63% (5 out of 8) of study participants achieved clinical remission, defined as UPCR
