"We are excited to start another clinical program in the renal space targeting an orphan indication where today there are no approved products," said CEO Renée Aguiar-Lucander.

Alport syndrome is a genetic disorder arising from the mutations in the genes that code for type 4 collagen. The type 4 collagen alpha chains are primarily located in the kidneys, eyes, and cochlea, and thus the condition is characterized by kidney disease, loss of hearing, and eye abnormalities. Eventually, patients present with proteinuria, hypertension, progressive loss of kidney function (gradual decline in GFR), and end-stage renal disease (ESRD). It is estimated that approximately 30,000 to 60,000 people in the United States (US) have this disorder, and it is a significant cause of chronic kidney disease (CKD), leading to ESRD in adolescents and young adults and accounting for 1.5% to 3.0% of children on renal replacement therapies in Europe and the US.^[1]

Through its subsidiary Calliditas Therapeutics Suisse SA, which will sponsor the planned phase 2 clinical study of setanaxib in Alport syndrome, Calliditas is currently investigating setanaxib in a Phase 2 proof-of-concept study in squamous cell carcinoma of the head and neck (SCCHN), as well as in a Phase 2b study in primary biliary cholangitis (PBC). Setanaxib is also being evaluated in an investigator-led study in idiopathic pulmonary fibrosis (IPF).
