Awards & highlights

Summary

This trial looks at how well exemestane works in treating patients with endometrial cancer or abnormal cell growth in the endometrium. Exemestane may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Who is the study for?

This trial is for postmenopausal women with complex atypical hyperplasia or low grade endometrial cancer who haven't had prior treatments. Participants must have adequate organ function, no recent invasive malignancies except certain skin cancers, not be on hormone therapy or strong CYP3A4 inducers, and able to take oral medications.

What is being tested?

The trial tests exemestane's effectiveness in treating specific endometrial conditions by blocking enzymes that promote cell growth. It includes a pharmacokinetic study to see how the body processes the drug, biomarker analysis, and questionnaires.

What are the potential side effects?

Exemestane may cause joint pain, hot flashes, fatigue, osteoporosis (bone thinning), mood swings and slight nausea. Since it lowers estrogen levels in the body which can affect bone density and cholesterol levels.
