Calliditas initiates clinical study to evaluate setanaxib in Alport Syndrome

STOCKHOLM, Nov. 30, 2023 /PRNewswire/ -- Calliditas Therapeutics AB (Nasdaq: CALT) (Nasdaq Stockholm: CALTX) ('Calliditas') today announced the initiation of a Phase 2 clinical study to evaluate setanaxib in Alport syndrome.

Calliditas is a company focused on developing and commercializing novel treatments in rare diseases with significant unmet medical needs.

This randomized, double-blind, placebo-controlled study will evaluate setanaxib in approximately 20 patients with a genetic diagnosis of Alport syndrome and significant proteinuria despite treatment with a renin-angiotensin system (RAS) blocker. The duration of treatment is 24 weeks. The objective is to evaluate the safety and tolerability of setanaxib in patients with Alport syndrome, as well as the effect of setanaxib on UPCR and eGFR compared to placebo.

 "There is an urgent clinical need in Alport syndrome for treatments that delay the progression to kidney failure," said Dr Rachel Lennon, Professor of Nephrology and Honorary Consultant Pediatric Nephrologist, University of Manchester (UK), and Coordinating Investigator for the study. "Alport syndrome can occur as early as the teenage years, when it causes major disruption to learning and education. Clinical trials allow new treatments such as setanaxib to be evaluated for safety and effectiveness in Alport syndrome."

Setanaxib is also being evaluated in Phase 2 studies in squamous cell carcinoma of the head and neck, primary biliary cholangitis, and idiopathic pulmonary fibrosis.
