ClinConnect Summary

This clinical trial is studying a medication called letrozole to see if it can help women with uterine leiomyosarcoma, a type of cancer that affects the uterus. The main goal of the trial is to find out if taking letrozole can help patients live without their cancer getting worse for a longer time. Women between the ages of 65 and 74 who have had surgery to remove their uterus and ovaries and have certain types of tumors may be eligible to participate. To qualify, participants need to have tumors that are positive for estrogen receptors, meaning the tumor cells have a certain protein that can help the cancer grow.

If you join this trial, you will take letrozole daily for your treatment. Before starting, you should be in good health overall, with specific organ functions meeting the study's requirements. The trial is currently looking for participants, so if you or someone you know might fit the criteria and is interested, it could be a chance to contribute to important research while receiving treatment. It's important to discuss any questions or concerns with your healthcare provider to understand if this trial is right for you.

Eligibility criteria

  • Inclusion Criteria:
  • 1. Patient or a legally authorized representative must have signed an approved informed consent and authorization permitting the release of personal health information.
  • 2. Patient must have histologically confirmed newly diagnosed uterine leiomyosarcoma with disease limited to the uterus (FIGO 2009 Stage I). Submission of pathology report documenting uterine leiomyosarcoma histology is required in the IRT Source Document Portal following randomization.
  • 3. Patient tumors must express ER positivity by immunohistochemistry (ER expression greater than 10% by immunohistochemistry). ER status test results must be provided at enrollment. Sites are required to report results of ER status testing in the IRT Source Document Portal.
  • 4. Patient must have completed hysterectomy and bilateral salpingo-oopherectomy no more than 12 weeks from enrollment.
  • 5. All patients must have NO measurable disease as defined by RECIST 1.1 within 6 weeks of enrollment. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be greater than or equal to 10 mm when measured by CT, MRI or caliper measurement by clinical exam; or greater than or equal to 20 mm when measured by chest x-ray. Lymph nodes must be greater than or equal to 15 mm in short axis when measured by CT or MRI.
  • 6. Patients must have an ECOG performance status of 0, 1, or 2.
  • 7. Patients must have adequate organ and marrow function as defined below:
  • NOTE: Institutional/laboratory upper limit of normal = ULN Institutional/laboratory lower limit of normal = LLN
  • Bone marrow function:
  • Absolute neutrophil count (ANC) greater than or equal to 1500 cells/mcl
  • Platelet count greater than or equal to 100,000 cells/mcl
  • Hemoglobin greater than or equal to 9.0 g/dL (Patients may receive erythrocyte transfusions to achieve this hemoglobin level at the discretion of the Investigator. Initial treatment must not begin earlier than the day after erythrocyte transfusion).
  • Renal function:
  • • Serum creatinine less than or equal to 1.5 x ULN
  • Hepatic function:
  • AST (aspartate aminotransferase) and ALT (alanine aminotransferase) less than or equal to 3.0 x ULN
  • Serum albumin greater than or equal to 2.5 g/dL
  • 8. Patient must be at least 18 years of age.
  • 9. Patient must be able to swallow oral medication.
  • Exclusion Criteria:
  • Exclusion Criteria 1. Patients who do not have pure uterine sarcomas (i.e., no mixed malignant mullerian tumors are permitted).
  • 2. Patients with any other severe concurrent disease, which would make the patient inappropriate for entry into this study, including significant hepatic, renal, or gastrointestinal diseases.
  • 3. Patients with concomitant invasive malignancy or a history of prior malignancy except non-melanoma skin cancer, in situ cervical cancer, or other cancer for which the patient has been disease-free for at least three years. Patients are also excluded if their previous cancer treatment contraindicates this protocol.
  • 4. Patients who have a history of taking any aromatase inhibitor within the past 5 years.
  • 5. Patients with active or uncontrolled systemic infection. 6. Patients with history of uncontrolled cardiac disease, i.e., uncontrolled hypertension (defined as systolic greater than 150 mm Hg or diastolic greater than 90 mm HR despite antihypertensive medications), unstable angina, recent myocardial infarction (within prior 6 months), uncontrolled congestive heart failure (NYHA Class II or greater), clinically significant cardiac arrhythmias, and cardiomyopathy with an ejection fraction under 40%.
  • 7. Patients currently receiving chemotherapy or radiation therapy. 8. Patients with severe hepatic impairment and/or cirrhosis. 9. Patients with duodenal stent or other GI disorder/defect that would interfere with absorption of oral medication.
  • 10. Patients deemed otherwise clinically unfit for clinical trial per investigators discretion.
  • 11. Patients with known hypersensitivity to any of the excipients of letrozole. 12. Patients who are pregnant or breast-feeding. 13. Patients who are currently part of or have participated in any clinical investigation with an investigational drug within 30 days of prior to enrollment.
  • 14. Patients currently using systemic estrogens, including herbals and supplements with estrogenic properties. The use of vaginal estrogen is permitted if symptoms are refractory to moisturizers and lubricants.
