Exclusion Criteria:

Patients with grade 2-3 endometrioid, uterine serous, clear cell, mucinous, squamous, transitional cell, sarcomas, or carcinosarcoma histology
Evidence of extrauterine spread of disease on imaging or during surgical evaluation
Patients who have prior therapy with everolimus or any other mammalian target of rapamycin (mTOR) inhibitor

Known intolerance or hypersensitivity to everolimus or other rapamycin analogs (e.g. sirolimus, temsirolimus)
Known intolerance or hypersensitivity to progesterone or its excipients
Known impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of oral everolimus (e.g., inability to take oral medication or a requirement for intravenous [IV] alimentation, prior surgical procedures affecting absorption, malabsorption syndrome, and active peptic ulcer disease) are excluded; subjects with ulcerative colitis, inflammatory bowel disease, or a partial or complete small bowel obstruction are also excluded, as are any patients who cannot swallow the capsule whole
Uncontrolled diabetes mellitus as defined by glycosylated hemoglobin (HbA1c) > 8% despite adequate therapy; patients with a known history of impaired fasting glucose or diabetes mellitus (DM) may be included, however blood glucose and antidiabetic treatment must be monitored closely throughout the trial and adjusted as necessary
Patients who have any severe and/or uncontrolled medical conditions such as: a) unstable angina pectoris, symptomatic congestive heart failure, myocardial infarction =< 6 months prior to start of everolimus, serious uncontrolled cardiac arrhythmia, or any other clinically significant cardiac disease; b) symptomatic congestive heart failure of New York Heart Association class III or IV; c) active (acute or chronic) or uncontrolled severe infection (not responding to antibiotics), liver disease such as cirrhosis, decompensated liver disease, and active and chronic hepatitis (i.e. quantifiable hepatitis B virus-deoxyribonucleic acid [HBV-DNA] and/or positive hepatitis B surface antigen [HbsAg], quantifiable hepatitis C virus-ribonucleic acid [HCV-RNA]); d) known severely impaired lung function (spirometry and diffusing capacity of the lung for carbon monoxide [DLCO] 50% or less of normal and oxygen [O2] saturation 88% or less at rest on room air); e) active, bleeding diathesis
Chronic treatment with corticosteroids or other immunosuppressive agents; topical or inhaled corticosteroids are allowed
Patients who have a known history of human immunodeficiency virus (HIV) seropositivity
Patients who have received live attenuated vaccines within 1 week of start of everolimus and during the study; patient should also avoid close contact with others who have received live attenuated vaccines; examples of live attenuated vaccines include intranasal influenza, measles, mumps, rubella, oral polio, Bacillus Calmette-Guerin (BCG), yellow fever, varicella and TY21a typhoid vaccines
Other malignancies within the past 3 years except for basal or squamous cell carcinoma of the skin
Active (acute or chronic) or uncontrolled severe infections (not responding to antibiotics), including acute pelvic inflammatory disease
Congenital or acquired uterine anomaly which distorts the uterine cavity
Genital actinomycosis
Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable or will not be able to complete the entire study
Patients who are currently part of or have participated in any clinical investigation with an investigational drug within 1 month prior to dosing
Women who are pregnant or nursing (lactating) women
Women of child-bearing potential (WOCBP), defined as women physiologically capable of becoming pregnant, must use one additional highly effective methods of contraception in addition to the LIUD during the study and 8 weeks after; acceptable effective contraception methods include combo of the following: a) barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/ vaginal suppository; b) total abstinence or; c) male/female sterilization; women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation > six weeks prior to randomization; in the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child-bearing potential
Women who are on contraindicated medications to everolimus must have confirmation from their physician that they may change or discontinue the medication if randomized to the LIUD + everolimus arm
