Summary

This trial tests a combination of two drugs, alpelisib and fulvestrant, in patients with a specific type of endometrial cancer. These patients have a genetic mutation (PIK3CA) and their cancer grows in response to estrogen. Alpelisib targets the mutation, while fulvestrant blocks estrogen, aiming to stop cancer growth. Alpelisib is the first drug of its kind approved for use with fulvestrant based on its effectiveness in treating similar types of cancer.

Who is the study for?
This trial is for adults with recurrent or primary endometrioid endometrial cancer that's ER-positive and PIK3CA-mutated. Participants must have measurable disease, be recovered from prior treatments, have good performance status (ECOG 0-1), controlled blood sugar levels, and adequate organ function. They can't have had certain previous inhibitors, other cancer types or treatments, uncontrolled diabetes type II, serious infections or conditions that could interfere with the study.
What is being tested?
The trial tests a combination of an alpelisib pill and fulvestrant injection in patients to see how well it works against specific mutations in endometrial cancer. The main goal is to measure the objective response rate (ORR) - basically how many patients see their tumors shrink or disappear after treatment.
What are the potential side effects?
Possible side effects include reactions at the injection site for fulvestrant, high blood sugar levels due to alpelisib which may require monitoring and management of diet or medication adjustments. Other common issues might involve digestive problems like nausea or diarrhea.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for endometrial cancer, such as PI3K inhibitors and estrogen receptor antagonists, work by targeting specific pathways that drive cancer growth. PI3K inhibitors like Alpelisib block the PI3K/AKT/mTOR pathway, which is often overactive in cancer cells due to mutations, thereby reducing cell proliferation and inducing apoptosis. Estrogen receptor antagonists like Fulvestrant bind to and degrade estrogen receptors, blocking the estrogen signaling that promotes the growth of hormone receptor-positive cancer cells. This dual approach is particularly effective for patients with PIK3CA mutations and estrogen receptor-positive tumors, addressing both genetic and hormonal factors driving the cancer.
