Compound class: Synthetic organic
Comment: Leniolisib (CDZ173) is an orally bioavailable, potent phosphatidylinositol 3-kinase inhibitor (PI3K) inhibitor, with selectivity for the PI3Kδ isoform [3]. Novartis originally developed CDZ173 as a treatment for autoimmune diseases, but has rapidly repurposed it for its potential in patients with Activated PI3K Delta Syndrome (APDS, a.k.a. p110 delta activating mutation causing senescent T cells, lymphadenopathy and immunodeficiency, or PASLI). APDS is an ultra-rare genetic immunodeficiency disease characterised by lymphoproliferation, recurrent infections from childhood, and an increased risk of EBV-associated lymphoma. APDS is known to be caused by autosomal dominant, gain-of-function mutations in the PIK3CD gene which encodes the PI3Kδ protein [4,7].
