PI3Kδ inhibitors are a class of drugs that target the delta isoform of phosphoinositide 3-kinase (PI3Kδ). These inhibitors work by blocking the activity of PI3Kδ, which is involved in signaling pathways that regulate cell growth, survival, and immune responses. By inhibiting PI3Kδ, these drugs help to suppress the proliferation of certain cells, including B cells and T cells. PI3Kδ inhibitors have shown promise in the treatment of diseases such as chronic lymphocytic leukemia (CLL), follicular lymphoma, and certain autoimmune disorders like rheumatoid arthritis. The market for PI3Kδ inhibitors is driven by several factors. Firstly, there is a growing prevalence of diseases such as chronic lymphocytic leukemia (CLL), follicular lymphoma, and autoimmune disorders, which are potential indications for PI3Kδ inhibitors. Secondly, advancements in research and development efforts led to the discovery and development of more selective and potent PI3Kδ inhibitors. According to the PubMed publication of Jan 2022, CLL accounts for 25–30% of all leukemia in Western Countries, with over 100,000 incidence cases and over 40,000 death cases globally reported in 2019. Companies such as Gilead, AstraZeneca, GSK, Incyte, Bayer, BeiGene, J&J, Novartis, Pharming Group, Sanofi, TG Therapeutics, and UCB currently cater to chronic lymphocytic leukemia (CLL), follicular lymphoma, and autoimmune disorders. Aliqopa (copanlisib) is one of the prominent drugs by Bayer, which is being used to treat follicular lymphoma and leukemia. Moreover, Zydelig (idelalisib) by Gilead and Ukoniq (Umbralisib) by TG Therapeutics are other prominent drugs that are used extensively in cases of mantle cell lymphoma and Hodgkin cell lymphoma respectively, apart from getting used in before mentioned indications. Moreover, many companies are coming up with new molecules in this space. For instance, Pharming Group is one such company that got the drug Joenja (Leniolisib) approved for the treatment of endocrine gland neoplasm and breast cancer.

Key Developments

  • In February 2023, Pharming Technologies B.V. in collaboration with Cmed, LabCorp Corporation of America Holdings, inc, CMIC co, ltd. (Japan), LabCorp central laboratory has started an open-label, single-arm study of the safety, pharmacokinetics, pharmacodynamics, and efficacy of Leniolisib in pediatric patients aged 4 to 11 years with activated phosphoinositide 3-kinase delta syndrome followed by an open-label long-term extension.
  • In April 2023, The FDA approved Pharming’s Leniolisib for activated phosphoinositide 3-kinase (PI3K) δ syndrome (APDS), a rare genetic disorder that weakens the immune system.

Target Indication Analysis of PI3K-Delta Inhibitors

The PI3Kδ inhibitors are primarily used to treat chronic lymphocytic leukemia (CLL), follicular lymphoma, and autoimmune disorders. PI3Kδ inhibitors also help to prevent Hodgkin lymphoma. For instance, Ukoniq (Umbralisib) is a drug by TG Therapeutics which is under trial for the treatment of ovarian epithelial cancer. In the treatment of leukemia, PI3Kδ inhibitor Copiktra (Duvelisib) is used widely. Through research and development, the indications in which PI3Kδ inhibitors can be used are getting expanded. For instance, PI3Kδ inhibitors are now under clinical trial for the treatment of rhabdoid tumors.
