Breakthrough FDA Approval: Iqirvo® for Primary Biliary Cholangitis

Introduction to Iqirvo®

GENFIT and Ipsen have announced that the FDA has granted accelerated approval for Iqirvo® (elafibranor) 80 mg tablets, marking a significant milestone in the treatment of Primary Biliary Cholangitis (PBC).

This new medication is intended for use in adults who have not responded adequately to ursodeoxycholic acid (UDCA) or those who are unable to tolerate UDCA.

What is Primary Biliary Cholangitis?

Primary Biliary Cholangitis (PBC) is a chronic liver disease characterized by the progressive destruction of the bile ducts within the liver. This damage can lead to bile build-up, causing further liver damage, and potentially, liver failure.

PBC primarily affects middle-aged women and often requires lifelong management. Until now, the primary treatment has been UDCA.

Mechanism of Action

Iqirvo® works as a peroxisome proliferator-activated receptor (PPAR) agonist. By activating PPAR-alpha and PPAR-delta, Iqirvo® helps reduce bile acid synthesis and inflammation within the liver. This dual action is believed to provide therapeutic benefits for patients with PBC.

While it shows promising results in reducing alkaline phosphatase (ALP) levels, further studies are required to confirm its long-term benefits and improvement in patient survival.

Clinical Trial Insights

The approval of Iqirvo® was based on findings from the Phase III ELATIVE® trial. This multi-center, double-blind, placebo-controlled study involved 161 participants who had an inadequate response to UDCA or could not tolerate UDCA.

The trial demonstrated that Iqirvo® significantly reduced ALP levels compared to a placebo, supporting its accelerated approval by the FDA.

Adverse Effects and Safety Information

While Iqirvo® offers new hope for patients with PBC, it's important to consider its potential side effects. Common adverse effects include weight gain, abdominal pain, nausea, vomiting, and diarrhea.

Serious risks include rhabdomyolysis, fractures, and liver injuries. Patients should undergo regular monitoring to detect any signs or symptoms early and manage them promptly.

Safety Measures

Patients are advised to have regular assessments for muscle pain, myopathy, and liver function during Iqirvo® treatment. In case of severe reactions or signs of liver damage, treatment should be interrupted, or the medication should be discontinued.

Pregnant women, those planning to become pregnant, or breastfeeding mothers should avoid using Iqirvo® due to potential risks to the fetus and infants.

Financial Impact and Future Prospects

GENFIT anticipates substantial milestone payments and future revenues from the commercialization of Iqirvo®. This financial boost will support further research, particularly into Acute on-Chronic Liver Failure (ACLF) and other liver diseases.

The collaboration between GENFIT and Ipsen aims to expand research and provide new therapeutic options for patients suffering from rare liver diseases.

The Path Forward

Iqirvo® represents a major advancement in the management of PBC, providing a new option for patients who have limited treatment choices. The FDA's accelerated approval signifies the potential of Iqirvo® to meet an urgent unmet medical need.

Continued clinical trials and real-world data will be crucial in validating its effectiveness and safety over the long term.
