Summary

This trial is testing a combination of two drugs, Everolimus and Letrozole, to treat women with specific types of recurrent or persistent cancers. Everolimus stops cancer cells from growing, and Letrozole reduces hormones that some cancers need to grow.

Who is the study for?
This trial is for post-menopausal women with recurrent or persistent ovarian, fallopian tube, primary peritoneal, or endometrial cancer that's resistant to platinum-based chemotherapy. Participants must have a performance status of ECOG 2 or better and can't have severe medical conditions like unstable heart disease, serious infections, severely impaired lung function, active bleeding disorders, or liver disease.
What is being tested?
The study tests the effectiveness of combining Everolimus (Afinitor®), an FDA-approved drug for various cancers including advanced kidney and breast cancer among others, with Letrozole in treating women whose ovarian or endometrial cancer has returned despite treatment.
What are the potential side effects?
Everolimus may cause side effects such as mouth ulcers, infections due to immune system suppression, lung problems like coughing and shortness of breath; skin issues; delayed wound healing; and increased cholesterol levels. Letrozole can lead to hot flashes, joint pain/stiffness/arthritis; fatigue; osteoporosis; high blood pressure.

Trial Design

1Treatment groups
Experimental Treatment
Group I: SingleExperimental Treatment1 Intervention
This is a single arm, non-randomized, open-label study with a combination of everolimus and letrozole once a day dosing . Each cycle would be 28days and patients would be scanned after every 3 cycles for response, until disease progression is documented

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
mTOR inhibitors, such as Everolimus, work by blocking the mTOR pathway, which is crucial for cell growth and proliferation. By inhibiting this pathway, these drugs can slow down or stop the growth of cancer cells. Aromatase inhibitors, like Letrozole, reduce the production of estrogen by blocking the enzyme aromatase, which converts androgens to estrogen. Since some endometrial cancers are estrogen-dependent, lowering estrogen levels can help control the growth of these tumors. These treatments are significant for Endometrial Cancer patients as they target specific pathways involved in cancer progression, potentially leading to more effective and personalized treatment options.
