- Background
Leniolisib is a potent and selective inhibitor of phosphoinositide 3-kinase δ (PI3Kδ). The FDA approved leniolisib on March 24, 2023, making it the first treatment for activated phosphoinositide 3-kinase delta syndrome (APDS).10 APDS is a primary immunodeficiency caused by mutations in genes encoding the PI3Kδ, thereby increasing the activity of PI3Kδ, causing immune dysfunction, and elevating susceptibility to infections.1,2 Leniolisib works to inhibit hyperactive PI3Kδ.9 Investigations for using leniolisib in primary Sjögren’s syndrome are ongoing.3

- Pharmacodynamics
Leniolisib works to block aberrant PI3Kδ-dependent signalling pathways of immune cells, such as B and T cells, neutrophils, monocytes, basophils, plasmocytoid dendritic cells, and mast cells.3 In vitro, leniolisib dose-dependently suppresses the PI3Kδ pathway hyperactivation in cell lines overexpressing p110δ mutants and in primary immune cells from patients with APDS.2 Ex vivo pharmacodynamics of leniolisib in the proportion of phosphorylated Akt (pAkt)- positive B cells were assessed intra-individually at 10, 30, and 70 mg twice daily for four weeks at each dose level in patients with APDS. Within the explored dose range, higher leniolisib plasma concentrations were generally associated with a higher reduction of pAkt-positive B cells. Higher doses were associated with a slightly higher peak and more sustained reduction. Treatment with leniolisib 70 mg twice a day at a steady state is estimated to produce a time-averaged reduction of pAkt-positive B cells by approximately 80%.9
- Mechanism of action
Phosphoinositide-3-kinase δ (PI3Kδ) is a lipid kinase activated downstream of tyrosine kinase receptors and G-protein–coupled receptors in immune cells.1,3,8 It mediates the PI3K/AKT pathway, which is involved in cell proliferation, growth, and survival.6,7 A heterodimer made up of a regulatory subunit (p85α) and a catalytic subunit (p110δ), PI3Kδ is primarily expressed on hematopoietic cells such as lymphocytes and myeloid cells. It converts phosphatidylinositol-4,5-bisphosphate (PIP2) to phosphatidylinositol-3,4,5-trisphosphate (PIP3), a signalling molecule that downstream proteins like the AKT kinase, which activate mammalian target of rapamycin (mTOR) complex I and inhibit FOXO family of transcription factors.1,2 APDS is associated with gain-of-function variants in the gene encoding p110δ or loss of function variants in the gene encoding p85α, each causing hyperactivity of PI3K-delta, reduced T cell function, lymphadenopathy, and immunodeficiency.1,9
Leniolisib inhibits PI3Kδ by blocking the active binding site in the p110δ subunit.2 In cell-free isolated enzyme assays, the selectivity was higher for PI3K-delta over PI3K-alpha (28-fold), PI3K-beta (43-fold), and PI3K-gamma (257-fold), as well as the broader kinome. In cell-based assays, leniolisib reduced pAKT pathway activity and inhibited proliferation and activation of B and T cell subsets. Leniolisib inhibits the signalling pathways that lead to increased production of PIP3, hyperactivity of the downstream mTOR/AKT pathway, and the dysregulation of B and T cells.9
Target Actions Organism APhosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit delta isoform inhibitorHumans - Absorption
The systemic drug exposure (AUC and Cmax) of leniolisib increases dose proportionally. During twice daily dosing approximately 12 hours apart, leniolisib accumulates approximately 1.4-fold (range of 1.0 to 2.2) in achieving steady-state. Steady-state drug concentrations can be expected to be reached after approximately two to three days. The Tmax is about one hour. Food has negligible effects on the systemic exposure of leniolisib.9
- Volume of distribution
The systemic decay in leniolisib plasma concentration over time is bi-exponential, indicating a distribution delay toward peripheral tissues. The volume of distribution of leniolisib is estimated to be 28.5 L in patients with APDS.9
- Protein binding
Leniolisib is 94.5% bound to plasma proteins.9
- Metabolism
About 60% of leniolisib is metabolized by the liver. Leniolisib undergoes oxidative metabolism, which is primarily mediated by CYP3A4 (94.5%), as well as CYP3A5 (3.5%), CYP1A2 (0.7%) and CYP2D6 (0.7%) to a minor extent.4,9 Few metabolites of leniolisib have been characterized in one study; however, no metabolites were abundant in plasma relative to the parent drug. Other metabolic pathways include dealkylation, demethylation, and hydroxylation.5
Other suggested excretion routes include intestinal secretion by BCRP and CYP1A1-mediated extrahepatic metabolism.4,9

- Route of elimination
The mean recovery of total 14C-radioactivity following a single oral dose of 70 mg 14C-leniolisib was 92.5% following 168 hours post-dose. About 67% and 25.5% of the recovered dose were in feces and urine, respectively. Of the recovered dose in urine, 6.32% was in unchanged parent drug form and the predominant drug-related material.9
- Half-life
The effective half-life is approximately seven hours. The apparent terminal elimination half-life is approximately 10 hours.9
- Clearance
In one study, healthy volunteers received leniolisib single ascending doses up to 400 mg and multiple ascending doses up to 140 mg twice daily for 14 days. Oral drug clearance from plasma (CL/F) was 4 L/h.4

- General Function
- Phosphoinositide-3-kinase (PI3K) phosphorylates phosphatidylinositol (PI) and its phosphorylated derivatives at position 3 of the inositol ring to produce 3-phosphoinositides (PubMed:9235916). Uses ATP and PtdIns(4,5)P2 (phosphatidylinositol 4,5-bisphosphate) to generate phosphatidylinositol 3,4,5-trisphosphate (PIP3) (PubMed:15135396). PIP3 plays a key role by recruiting PH domain-containing proteins to the membrane, including AKT1 and PDPK1, activating signaling cascades involved in cell growth, survival, proliferation, motility and morphology. Mediates immune responses. Plays a role in B-cell development, proliferation, migration, and function. Required for B-cell receptor (BCR) signaling. Mediates B-cell proliferation response to anti-IgM, anti-CD40 and IL4 stimulation. Promotes cytokine production in response to TLR4 and TLR9. Required for antibody class switch mediated by TLR9. Involved in the antigen presentation function of B-cells. Involved in B-cell chemotaxis in response to CXCL13 and sphingosine 1-phosphate (S1P). Required for proliferation, signaling and cytokine production of naive, effector and memory T-cells. Required for T-cell receptor (TCR) signaling. Mediates TCR signaling events at the immune synapse. Activation by TCR leads to antigen-dependent memory T-cell migration and retention to antigenic tissues. Together with PIK3CG participates in T-cell development. Contributes to T-helper cell expansion and differentiation. Required for T-cell migration mediated by homing receptors SELL/CD62L, CCR7 and S1PR1 and antigen dependent recruitment of T-cells. Together with PIK3CG is involved in natural killer (NK) cell development and migration towards the sites of inflammation. Participates in NK cell receptor activation. Plays a role in NK cell maturation and cytokine production. Together with PIK3CG is involved in neutrophil chemotaxis and extravasation. Together with PIK3CG participates in neutrophil respiratory burst. Plays important roles in mast-cell development and mast cell mediated allergic response. Involved in stem cell factor (SCF)-mediated proliferation, adhesion and migration. Required for allergen-IgE-induced degranulation and cytokine release. The lipid kinase activity is required for its biological function. Isoform 2 may be involved in stabilizing total RAS levels, resulting in increased ERK phosphorylation and increased PI3K activity

- A cytochrome P450 monooxygenase involved in the metabolism of steroid hormones and vitamins (PubMed:10681376, PubMed:11093772, PubMed:12865317, PubMed:2732228). Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds (PubMed:10681376, PubMed:11093772, PubMed:12865317, PubMed:2732228). Exhibits high catalytic activity for the formation of catechol estrogens from 17beta-estradiol (E2) and estrone (E1), namely 2-hydroxy E1 and E2 (PubMed:12865317). Catalyzes 6beta-hydroxylation of the steroid hormones testosterone, progesterone, and androstenedione (PubMed:2732228). Catalyzes the oxidative conversion of all-trans-retinol to all-trans-retinal, a rate-limiting step for the biosynthesis of all-trans-retinoic acid (atRA) (PubMed:10681376). Further metabolizes all trans-retinoic acid (atRA) to 4-hydroxyretinoate and may play a role in hepatic atRA clearance (PubMed:11093772). Also involved in the oxidative metabolism of xenobiotics, including calcium channel blocking drug nifedipine and immunosuppressive drug cyclosporine (PubMed:2732228)

- In vitro, leniolisib is a substrate and an inhibitor of the hepatic efflux transporter BCRP.
- General Function
- Broad substrate specificity ATP-dependent transporter of the ATP-binding cassette (ABC) family that actively extrudes a wide variety of physiological compounds, dietary toxins and xenobiotics from cells (PubMed:11306452, PubMed:12958161, PubMed:19506252, PubMed:20705604, PubMed:28554189, PubMed:30405239, PubMed:31003562). Involved in porphyrin homeostasis, mediating the export of protoporphyrin IX (PPIX) from both mitochondria to cytosol and cytosol to extracellular space, it also functions in the cellular export of heme (PubMed:20705604, PubMed:23189181). Also mediates the efflux of sphingosine-1-P from cells (PubMed:20110355). Acts as a urate exporter functioning in both renal and extrarenal urate excretion (PubMed:19506252, PubMed:20368174, PubMed:22132962, PubMed:31003562, PubMed:36749388). In kidney, it also functions as a physiological exporter of the uremic toxin indoxyl sulfate (By similarity). Also involved in the excretion of steroids like estrone 3-sulfate/E1S, 3beta-sulfooxy-androst-5-en-17-one/DHEAS, and other sulfate conjugates (PubMed:12682043, PubMed:28554189, PubMed:30405239). Mediates the secretion of the riboflavin and biotin vitamins into milk (By similarity). Extrudes pheophorbide a, a phototoxic porphyrin catabolite of chlorophyll, reducing its bioavailability (By similarity). Plays an important role in the exclusion of xenobiotics from the brain (Probable). It confers to cells a resistance to multiple drugs and other xenobiotics including mitoxantrone, pheophorbide, camptothecin, methotrexate, azidothymidine, and the anthracyclines daunorubicin and doxorubicin, through the control of their efflux (PubMed:11306452, PubMed:12477054, PubMed:15670731, PubMed:18056989, PubMed:31254042). In placenta, it limits the penetration of drugs from the maternal plasma into the fetus (By similarity). May play a role in early stem cell self-renewal by blocking differentiation (By similarity)

- General Function
- Mediates the Na(+)-independent uptake of organic anions (PubMed:10358072, PubMed:15159445, PubMed:17412826). Shows broad substrate specificity, can transport both organic anions such as bile acid taurocholate (cholyltaurine) and conjugated steroids (dehydroepiandrosterone 3-sulfate, 17-beta-glucuronosyl estradiol, and estrone 3-sulfate), as well as eicosanoids (prostaglandin E2, thromboxane B2, leukotriene C4, and leukotriene E4), and thyroid hormones (T4/L-thyroxine, and T3/3,3',5'-triiodo-L-thyronine) (PubMed:10358072, PubMed:10601278, PubMed:10873595, PubMed:11159893, PubMed:12196548, PubMed:12568656, PubMed:15159445, PubMed:15970799, PubMed:16627748, PubMed:17412826, PubMed:19129463, PubMed:26979622). Can take up bilirubin glucuronides from plasma into the liver, contributing to the detoxification-enhancing liver-blood shuttling loop (PubMed:22232210). Involved in the clearance of endogenous and exogenous substrates from the liver (PubMed:10358072, PubMed:10601278). Transports coproporphyrin I and III, by-products of heme synthesis, and may be involved in their hepatic disposition (PubMed:26383540). May contribute to regulate the transport of organic compounds in testes across the blood-testis-barrier (Probable). Can transport HMG-CoA reductase inhibitors (also known as statins), such as pravastatin and pitavastatin, a clinically important class of hypolipidemic drugs (PubMed:10601278, PubMed:15159445, PubMed:15970799). May play an important role in plasma and tissue distribution of the structurally diverse chemotherapeutic drug methotrexate (PubMed:23243220). May also transport antihypertension agents, such as the angiotensin-converting enzyme (ACE) inhibitor prodrug enalapril, and the highly selective angiotensin II AT1-receptor antagonist valsartan, in the liver (PubMed:16624871, PubMed:16627748). Shows a pH-sensitive substrate specificity towards prostaglandin E2 and T4 which may be ascribed to the protonation state of the binding site and leads to a stimulation of substrate transport in an acidic microenvironment (PubMed:19129463). Hydrogencarbonate/HCO3(-) acts as the probable counteranion that exchanges for organic anions (PubMed:19129463)
