Iqirvo (elafibranor) receives FDA accelerated approval as a first-in-class PPAR treatment for primary biliary cholangitis
Ipsen announced that the FDA has granted accelerated approval for Iqirvo (elafibranor) 80 mg tablets for the treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have an inadequate response to UDCA, or as monotherapy in patients unable to tolerate UDCA
Iqirvo may be prescribed immediately in the U.S. for eligible patients. This indication is approved under accelerated approval based on reduction of alkaline phosphatase (ALP). Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). Iqirvo is not recommended for people who have or develop decompensated cirrhosis (e.g., ascites, variceal bleeding, hepatic encephalopathy).
“For a significant number of people living with PBC, available treatments do not control the condition and may exacerbate symptoms of PBC. Left unmanaged, PBC can progress, leading to liver failure and in some cases, the need for a liver transplant,” said Christelle Huguet, Executive Vice President, Head of Research and Development at Ipsen. “Iqirvo demonstrated statistically significant improvements in biochemical response compared to UDCA alone. Iqirvo is therefore a much-needed treatment option and the first new medicine for PBC in nearly a decade.”
Iqirvo is a first-in-class oral, once-daily peroxisome proliferator-activated receptor (PPAR) agonist. Iqirvo was in-licensed from Genfit in 2021. The accelerated approval of Iqirvo is based on data from the Phase III ELATIVE trial published in the New England Journal of Medicine . The ELATIVE trial demonstrated that 13 times more patients achieved the composite primary endpoint of biochemical response when treated with Iqirvo plus UDCA (n=108) versus placebo plus UDCA (=53) (respectively 51% versus 4% for a 47% treatment difference). ALP is a biochemical marker and is used as a surrogate endpoint in PBC trials. Secondary endpoints showed normalization in ALP levels in only Iqirvo-treated patients (15% for Iqirvo plus UDCA (n=108) versus 0% for placebo plus UDCA (n=53)). Most patients (95%) received study treatment (Iqirvo or placebo) in combination with UDCA.
