   • Subjects with endometrial cancer with:

     • Documented/locally determined AKT1, PIK3CA, or PIK3R1 mutations with or without PTEN deficiency
     • ER+ status
4. Female subjects of child-bearing potential must have a negative serum or urine pregnancy test within 72 hours prior to administration of the first dose of study drug. "Women of childbearing potential" is defined as sexually mature women who have not undergone hysterectomy and/or bilateral oophorectomy, or who have not been naturally postmenopausal for at least 12 consecutive months prior to administration of the first dose of the study drug.
5. Measurable or evaluable disease
6. Subjects must agree to provide requested amount of archival and/or fresh tissue biopsy samples at baseline for mutational analysis by the Sponsor's central laboratory.
7. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2
8. Life expectancy ≥ 12 weeks
9. Failure to respond to or refractory to approved/standard therapy; or for whom standard therapy does not exist, or is not tolerable; or for whom approved/standard therapy is not considered to be sufficient or appropriate by the Investigator.

10. Adequate organ function as indicated by the following laboratory values. All laboratory tests must be obtained within 7 days prior to the first dose of study treatment:

    • Hematological

      - Absolute neutrophil count (ANC) ≥ 1.0 x 109/L

      - Platelet count (Plt) ≥ 100 x 109/L

      - Hemoglobin (Hb) ≥ 8 g/dL

    • Renal

      • Serum creatinine ≤ 1.5 x upper limit of normal (ULN) or
      • Calculated creatinine clearance ≥ 60 mL/min /1.73 m2 for subjects with serum creatinine levels > 1.5 x institutional ULN

    • Hepatic

      • Total bilirubin ≤ 1.5 x ULN or
      • Direct bilirubin ≤ ULN for subjects with total bilirubin levels > 1.5 x ULN
      • AST and ALT ≤ 3 x ULN or ≤ 5 x ULN for subjects with known liver metastases
    • Metabolic - Glycated hemoglobin (HbA1c) ≤ 8%
11. If a subject is currently receiving bisphosphonates or denosumab, the subject must have received the bisphosphonates or denosumab for at least four weeks before starting study treatment. Initiation of bisphosphonates or denosumab during the study may be allowed provided the subject completes the first cycle of treatment without any DLT and the Investigator rules out tumor progression.
12. Male or female subjects of child-bearing potential must agree to use double-barrier contraceptive measures, oral contraception, or avoidance of intercourse during and after the study (3 months after the last dose of ARQ 092 or anastrozole, whichever is longer)

Exclusion Criteria:

1. Anti-cancer therapy, such as chemotherapy, immunotherapy, targeted and hormonal/endocrine therapy, or investigational agents within five half-lives or two weeks (whichever is shorter) for oral drugs, five half-lives or four weeks (whichever is shorter) for intravenous drugs, and six weeks for nitrosoureas, mitomycin C, or bevacizumab prior to administration of the first dose of study drug

   • To be eligible for study treatment, toxicity from prior treatment must recover to Grade ≤ 1, except for alopecia
   • Concurrent systemic high-dose corticosteroids when used intermittently in an antiemetic regimen for central nervous system (CNS) metastases management or as a part of the premedication regimen are allowed
   • Prior hormonal therapy (including, but not limited to, tamoxifen, megestrol acetate, fulvestrant, and GnRH analogs) for the treatment of recurrent/advanced endometrial cancer are not allowed

2. Radiation therapy within four weeks prior to administration of the first dose of study drug

   • To be eligible for study treatment, radiation therapy-related toxicity must recover to Grade ≤ 1 prior to administration of the first dose of study drug. Concurrent palliative radiotherapy for local pain-control may be allowed, provided the subject does not meet criteria of progressive disease and treated lesions will not be included in the target/non-target lesion assessment.

3. Major surgical procedure within four weeks prior to administration of the first dose of study drug
