Definitions

• the present application provides methods of treating PI3K5 related disorders using pyrazolopyrimidine derivatives.
• BCR B-cell receptor
• Class I PI3Ks are heterodimeric lipid kinases composed of a regulatory (p85 or plOl) and a catalytic (pi 10) subunit (Chalhoub N. et al, Annual review of pathology, 2009;4:127-150).
• Each of the 4 tissue-specific pi 10 subunit isoforms (Class I A: a, b, and d; Class IB: g) confers unique physiologic functions on the corresponding PI3K isoforms, including insulin signaling and angiogenesis (PI3Ka) (Foukas L.C. et al, Nature,
• the PI3K5 isoform functions as a critical node in signaling networks that regulate B-cell growth and survival, and its aberrant activation is a key event in malignant transformation of B-cells (Kang S. et al, Proceedings of the National Academy of Sciences of the United States of America, 2005;102(3):802-807; Puri K.D., Gold M.R., Frontiers in
• Prognosis for patients with relapsed or refractory B-cell non-Hodgkin lymphoma is generally poor.
• OS 5-year overall survival
• FL follicular lymphoma
• Prognosis is worse for patients with relapsed aggressive NHL subtypes, with a median survival of 3.6 and 4.4 months among patients with relapsed diffuse large B-cell lymphoma (DLBCL) who had failed first-line and second-line salvage regimens, respectively (Van Den Neste E.
• NCCN Clinical Practice Guidelines in Oncology NCCN
• PI3K isoforms factors in their distinct biological functions. Genetic ablation of either PI3Koc or RI3Kb results in embryonic lethality, indicating that PI3Koc and RI3Kb have essential and non-redundant functions, at least during development
• mice which lack RI3Kg and PI3K6 are viable, fertile and have a normal life span although they show an altered immune system.
• RI3Kg deficiency leads to impaired recruitment of macrophages and neutrophils to sites of inflammation as well as impaired T cell activation (Sasaki, et al., Science, 2000, 287(5455): 1040-6).
• PI3K8-mutant mice have specific defects in B cell signaling that lead to impaired B cell development and reduced antibody responses after antigen stimulation (Clayton, et al., J Exp Med. 2002, 196(6):753-63; Jou, et al., Mol Cell Biol. 2002, 22(24):8580-91; Okkenhaug, et al., Science, 2002, 297(5583): 1031-4).
• RI3Kg and PI3K8-mutant mice suggest that these enzymes may play a role in inflammation and other immune-based diseases and this is borne out in preclinical models.
• PI3Ky-mutant mice are largely protected from disease in mouse models of rheumatoid arthritis (RA) and asthma (Camps, et al., Nat Med. 2005, 11(9):936-43; Thomas, et al., Eur J Immunol. 2005,
• B cells support T-cell autoreactivity, an important component of inflammatory autoimmune diseases. Once activated and matured, B cells can traffic to sites of inflammation and recruit inflammatory cells or differentiate to plasmablasts. Thus, activity of B-cells can be affected by targeting B-cell stimulatory cytokines, B-cell surface receptors, or via B- cell depletion.
• Rituximab an IgGl k mouse/human chimeric monoclonal antibody directed against the B-cell surface receptor CD20— has been shown to deplete CD20+ B cells.
• rituximab has been shown to have efficacy in treating idiopathic thrombocytopenic purpura, autoimmune hemolytic anemia, or vasculitis.
• treatment with rituximab resulted in remission of the disease in patients suffering from anti-neutrophil cytoplasm antibody associated (ANCA) systemic vasculitis (AASV) with demonstrated peripheral B-cell depletion (Walsh, 2007; Lovric, Nephrol Dial
• thrombocytopenic purpura (Garvey, British Journal of Haematology, (2008) 141, 149-169; Godeau, Blood (2008), 112(4), 999-1004; Medeo, European Journal of Haematology, (2008) 81, 165-169) and autoimmune hemolytic anemia (Garvey, British Journal of Haematology, (2008) 141, 149-169).
• PI3K6 signaling has been tied to B cell survival, migration, and activation (Puri, Frontiers in Immunology, 2012, 3(256), 1-16, at pages 1-5; and Clayton, J Exp Med, 2002, 196(6):753-63).
• RI3Kd is required for antigen-dependent B-cell activation driven by B cell receptor.
• B-cell adhesion, survival, activation, and proliferation By blocking B-cell adhesion, survival, activation, and proliferation, RI3Kd inhibition can impair the ability of B cells to activate T cells, preventing their activation and reducing secreation of autoantibodies and pro-inflammatory cytokines.
• RI3Kd inhibitors would be expected to treat B cell mediated diseases that were treatable by similar methods such as B cell depletion by rituximab.
• RI3Kd inhibitors have been shown to be useful mouse models of various autoimmune diseases that are also treatable by rituximab such as arthritis (Puri (2012)).
• innate-like B cells which are linked to autoimmunity are sensitive to RI3Kd activity, as MZ and B-l cells are nearly absent in mice lacking the pi 10d gene (Puri (2012).
• RI3Kd inhibitors can reduce trafficking of and activation of MZ and B-l cells, which are implicated in autoimmune diseases.
• PI3K8 Consistent overexpression of PI3K8 is observed in acute myeloblastic leukemia (Sujobert, et al., Blood, 2005, 106(3): 1063-6) and inhibitors of PI3K8 can prevent the growth of leukemic cells (Billottet, et al., Oncogene. 2006, 25(50):6648-59). Elevated expression of RI3Kg is seen in chronic myeloid leukemia (Hickey, et al., J Biol Chem. 2006, 281(5):2441-50).
• RI3Kb, RI3Kg and PI3K8 have also been observed in cancers of the brain, colon and bladder (Benistant, et al., Oncogene, 2000, 19(44):5083-90; Mizoguchi, et al., Brain Pathol. 2004, 14(4):372-7; Knobbe, et al., Neuropathol Appl Neurobiol. 2005, 31(5):486-90). Further, these isoforms have all been shown to be oncogenic in cell culture (Kang, et al., 2006).
• rituximab improved treatment outcomes for patients with B-cell NHL (Chao M.P., Cancer Management and Research. 2013;5:251-269; Nandagopal L., Mehta A, Expert Review of Hematology, 2017;10(3):259-273).
• the PI3K inhibitor class has shown promise, but clinical use has been limited by toxicities.
• the first-in-class PI3K5-selective inhibitor, idelalisib has been associated with considerable toxicity, including hepatotoxicity (Coutre S.E., et al, Leukemia & Lymphoma, 2015;56(10):2779-2786; Gopal A., Graf S., Expert opinion on pharmacotherapy, 2016;17(2):265-274), as well as increased risk of opportunistic infection (Lampson B.L. et al, Blood, 2016;128(2): 195-203), and requires frequent monitoring.

• Diarrhea/colitis and rash toxicities common to PI3K inhibitors, were 2 of the most frequent toxicities observed in this study; nevertheless, the majority of diarrhea events were of grade 1 or 2 and were manageable. The majority of grade 3/4 diarrhea/colitis and rash occurred after the first disease assessment; overall any grade diarrhea/colitis or rash led to treatment discontinuation in 9/72 (13%) of patients, including 3 patients with diarrhea/colitis who were positive upon rechallenge at the same dose. Grade 4 neutropenia (6%) was observed only during QD dosing (earliest occurring after 21 days of treatment). The safety profile associated with the 20 mg QD dose was generally consistent with that observed for all doses combined and with that observed for each individual dose level (data not shown), although relatively few patients were dosed at levels below 20 mg QD and above 30 mg QD.
• the intermittent portion of the dosing regimen which was implemented to decrease the incidence of late-onset TEAEs, was based on comparative PK/PD simulation with copanlisib (Patnaik A., et al, Annals of Oncology, 2016;27(10): 1928-1940). Without being bound by theory, the 20 mg QW regimen is anticipated to provide similar pAKT inhibition as expected from QW dosing of copanlisib. Encouragingly, none of the 26 patients who received QW dosing discontinued study treatment due to TEAEs, based on data accrued during a 105 patient-month period.
