Leniolisib, a selective phosphoinositide 3-kinase-delta inhibitor, is now approved for activated PI3Kδ syndrome (APDS). This marks a significant milestone for treating this rare immunodeficiency disorder.
Area of Science:
- Immunology
- Pharmacology
- Genetics
Background:
- Activated PI3Kδ syndrome (APDS) is a rare primary immunodeficiency disorder.
- Phosphoinositide 3-kinase-delta (PI3Kδ) pathway dysregulation is central to APDS pathogenesis.
- Targeting the PI3Kδ pathway offers a potential therapeutic strategy for APDS.
Purpose of the Study:
- To summarize the development milestones of leniolisib.
- To highlight the regulatory journey leading to the first approval of leniolisib for APDS.
- To provide an overview of leniolisib as a PI3Kδ inhibitor for immunodeficiency disorders.
Main Methods:
- Review of clinical development data and regulatory submissions for leniolisib.
- Analysis of scientific literature on PI3Kδ inhibitors and APDS.
- Summary of key preclinical and clinical trial findings (details not provided in abstract).
Main Results:
- Leniolisib (JOENJA®) received its first approval in March 2023 for APDS in patients 12 years and older.
- Leniolisib is under regulatory review in the European Union for APDS.
- Development for Sjögren's syndrome was discontinued.
Conclusions:
- Leniolisib represents a novel targeted therapy for APDS.
- The approval signifies a breakthrough in treating this specific immunodeficiency.
- Further regulatory reviews are ongoing in other regions.
