TAS-117 is a potent, selective, orally active allosteric Akt inhibitor (with IC50s of 4.8, 1.6, and 44 nM for Akt1, 2, and 3, respectively). TAS-117 triggers anti-myeloma activities and enhances fatal endoplasmic reticulum (ER) stress induced by proteasome inhibition. TAS-117 induces apoptosis and autophagy[1].
TAS-117 (1 μM; 6 hours) blocks basal phosphorylation of Akt and downstream p-FKHR/FKHRL1 in MM cells with high baseline p-Akt[1].TAS-117 (0-10 μM; 72 hours) selectively inhibits Akt and induces cytotoxicity in MM cells with high baseline phosphorylation of Akt[1].TAS-117 abrogates the cytoprotective effect of the bone marrow microenvironment associated with Akt inhibition in both MM cells and BMSCs. TAS-117 enhances Carfilzomib-induced cytotoxicity and fatal ER stress in MM cells. TAS-117 (0.5, 1 μM) triggers G0/G1 arrest followed by apoptosis, associated with induction of autophagy and endoplasmic reticulum stress response[1].TAS-117 enhances bortezomib-induced cytotoxicity, associated with increased CHOP (a fatal ER-stress marker) and PARP cleavage and blockade of bortezomib-induced p-Akt, suggesting that TAS-117 augments Bortezomib-induced ER stress and apoptotic signaling[1].
TAS-117 (12-16 mg/kg; p.o.; daily for 5 days a week, 21 days) inhibits tumor growth in murine xenograft models of human MM[1].TAS-117 enhances bortezomib-induced MM cytotoxicity in vivo[1].

A phase II study of TAS-117 in patients with advanced solid tumors harboring germline PTEN-inactivating mutations
Future Oncol 2022 Sep;18(30):3377-3387.PMID:36039910DOI:10.2217/fon-2022-0305.
PTEN acts as a potent tumor suppressor within the PI3K/AKT/mTOR pathway. Germline mutations in the PTEN gene are a hallmark of PTEN hamartoma tumor syndrome, which includes Cowden syndrome, where they appear to elevate lifetime risk of cancer. Targeted AKT directed therapy has been proposed as an effective approach in cancer patients having germline PTEN mutations. The mechanism of action, safety and dosing regimen for the novel allosteric AKT inhibitor TAS-117 have been explored in a phase I study in Japan in which activity was observed against certain tumor types. Here we describe the study protocol of an international, two-part phase II study evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics and antitumor activity of TAS-117 in patients with advanced solid tumors harboring germline PTEN-inactivating mutations.
Phase 2 study of TAS-117, an allosteric akt inhibitor in advanced solid tumors harboring phosphatidylinositol 3-kinase/v-akt murine thymoma viral oncogene homolog gene mutations
Invest New Drugs 2021 Oct;39(5):1366-1374.PMID:33723724DOI:10.1007/s10637-021-01085-7.
TAS-117 is a potent and selective allosteric pan-v-akt murine thymoma viral oncogene homolog (Akt) inhibitor. We conducted a single-arm single-center phase 2 study of TAS-117 in heavily treated patients with tumors refractory to systemic chemotherapy and harboring phosphatidylinositol 3-kinase (PI3K)/Akt mutations. Patients with gastrointestinal (GI) cancers were orally administered 16 mg TAS-117 daily, and those with non-GI tumors were administered 24 mg on a 4 days on/3 days off schedule. The primary endpoint was overall response rate (ORR). Secondary endpoints included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), PFS ratio, safety, and tolerability. Thirteen patients were enrolled: eight with non-GI (breast, ovarian, endometrial, and non-small cell lung) and five with GI (colon, rectal, gastric, and gallbladder) cancers. Ten patients were treated with TAS-117 after ≥ 4 lines of therapy. Twelve patients showed PIK3 catalytic subunit alpha (PIK3CA) mutations; one harbored an Akt1E17K mutation. The median treatment duration was 1.4 months; the median number of treatment cycles was 2. The ORR was 8 %, and DCR was 23 %. The median PFS and OS were 1.4 and 4.8 months, respectively. Grade 3-4 treatment-related adverse events were anorexia (grade 3, 8 %) and hyperglycemia (grade 3, 8 %; grade 4, 8 %).Grade 3-4 treatment-related adverse events occurred in 27 % of grade 3 anorexia (9 %) and hyperglycemia (grade 3, 8 %; grade 4, 9\%). TAS-117 showed limited antitumor activity and manageable toxicity. Clinical efficacy was observed in patients with ovarian cancer harboring PIK3CA E545K mutations and in patients with breast cancer harboring PIK3CA H1047R and Akt1E17K mutations.Trial registration: This study was retrospectively registered with ClinicalTrial.gov (NCT03017521 on January 11, 2017).
[Novel epigenetic therapies for multiple myeloma]
Rinsho Ketsueki 2021;62(4):314-320.PMID:33967157DOI:10.11406/rinketsu.62.314.
To achieve a cure of multiple myeloma (MM), we have been developing novel therapies targeting epigenetic aberrations. EZH2 and its homolog EZH1 are the histone lysine methyltransferases inducing the repressive mark of H3K27me3. UNC1999 is a dual inhibitor of EZH2 and EZH1, showing significant anti-MM activities. It also synergizes with proteasome inhibitors, associated with derepression of NR4A1 and downregulation of MYC. Moreover, UNC1999 and a selective Akt inhibitor TAS-117 synergistically inhibit the growth of MM cells through epigenetic mechanisms. TAS-117 induces downregulation of EZH2 and compensatory upregulation of EZH1, which is inhibited by UNC1999. Interestingly, a microtubule polymerization inhibitor PTC596 cooperatively downregulates BMI1 protein with proteasome inhibitors, exhibiting in-vitro and in-vivo cytotoxicity in MM cells. Finally, our mouse model with concurrent loss of the histone demethylase Utx and the activating mutation of Braf V600E in post germinal center B cells demonstrates mature B-cell malignancies including plasma cell neoplasms. Our ongoing analyses will reveal the pathogenesis of MM induced by somatic mutations, and this model is a useful tool for the development of novel molecular-targeted therapies for MM patients.
Selective and potent Akt inhibition triggers anti-myeloma activities and enhances fatal endoplasmic reticulum stress induced by proteasome inhibition
Cancer Res 2014 Aug 15;74(16):4458-69.PMID:24934808DOI:10.1158/0008-5472.CAN-13-3652.
The PI3K/Akt pathway plays a crucial role in the pathogenesis of multiple myeloma (MM) in the bone marrow (BM) milieu. However, efficacy of selective and potent Akt inhibition has not yet been fully elucidated. In this study, we, therefore, examined the biologic impact of selective and potent Akt inhibition by a novel allosteric inhibitor TAS-117. TAS-117 induced significant growth inhibition, associated with downregulation of phosphorylated Akt (p-Akt), selectively in MM cell lines with high baseline p-Akt. Cytotoxicity of TAS-117 was also observed in patient MM cells, but not in normal peripheral blood mononuclear cells. Importantly, TAS-117 induced significant cytotoxicity in MM cells even in the presence of BM stromal cells, associated with inhibition of IL6 secretion. Oral administration of TAS-117 significantly inhibited human MM cell growth in murine xenograft models. TAS-117 triggered apoptosis and autophagy, as well as induction of endoplasmic reticulum (ER) stress response with minimal expression of C/EBP homologous protein (CHOP), a fatal ER stress marker. Importantly, TAS-117 enhanced bortezomib-induced cytotoxicity, associated with increased CHOP and PARP cleavage and blockade of bortezomib-induced p-Akt, suggesting that TAS-117 augments bortezomib-induced ER stress and apoptotic signaling. Carfilzomib-induced cytotoxicity was similarly enhanced by TAS-117. Importantly, TAS-117 enhanced bortezomib-induced cytotoxicity in vivo, associated with prolonged host survival. Our results show that selective and potent Akt inhibition by TAS-117 triggers anti-MM activities in vitro and in vivo, as well as enhances cytotoxicity of proteasome inhibition, providing the preclinical framework for clinical evaluation of selective Akt inhibitors, alone and in combination with proteasome inhibitors in MM.
Akt inhibition synergizes with polycomb repressive complex 2 inhibition in the treatment of multiple myeloma
Cancer Sci 2019 Dec;110(12):3695-3707.PMID:31571328DOI:10.1111/cas.14207.
Polycomb repressive complex 2 (PRC2) components, EZH2 and its homolog EZH1, and PI3K/Akt signaling pathway are focal points as therapeutic targets for multiple myeloma. However, the exact crosstalk between their downstream targets remains unclear. We herein elucidated some epigenetic interactions following Akt inhibition and demonstrated the efficacy of the combined inhibition of Akt and PRC2. We found that TAS-117, a potent and selective Akt inhibitor, downregulated EZH2 expression at the mRNA and protein levels via interference with the Rb-E2F pathway, while EZH1 was compensatively upregulated to maintain H3K27me3 modifications. Consistent with these results, the dual EZH2/EZH1 inhibitor, UNC1999, but not the selective EZH2 inhibitor, GSK126, synergistically enhanced TAS-117-induced cytotoxicity and provoked myeloma cell apoptosis. RNA-seq analysis revealed the activation of the FOXO signaling pathway after TAS-117 treatment. FOXO3/4 mRNA and their downstream targets were upregulated with the enhanced nuclear localization of FOXO3 protein after TAS-117 treatment. ChIP assays confirmed the direct binding of FOXO3 to EZH1 promoter, which was enhanced by TAS-117 treatment. Moreover, FOXO3 knockdown repressed EZH1 expression. Collectively, the present results reveal some molecular interactions between Akt signaling and epigenetic modulators, which emphasize the benefits of targeting PRC2 full activity and the Akt pathway as a therapeutic option for multiple myeloma.
