Inavolisib for Breast Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effectiveness of inavolisib, a new potential drug, when combined with other treatments for a specific type of breast cancer that has not been previously treated. The focus is on individuals with Stage II-III breast cancer that is estrogen receptor-positive and HER2-negative, with a specific PIK3CA gene mutation. Participants will receive various combinations of inavolisib, letrozole, and ribociclib over several treatment cycles. Ideal candidates for this trial have a confirmed PIK3CA mutation and tumors that are estrogen receptor-positive and HER2-negative, and are prepared for surgery after treatment. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you have Type 2 diabetes requiring ongoing treatment, you may not be eligible to participate.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that inavolisib, used alone or with other breast cancer treatments, is generally safe. Studies indicate that patients have tolerated the treatment well, even those on it for a year or more. Reports mention that side effects are usually manageable, allowing doctors to control them if they occur. While some patients might experience side effects, the treatment remains safe for continued use.12345
Why are researchers excited about this trial's treatments?
Inavolisib is unique because it targets the PI3K pathway, which is crucial for cancer cell growth and survival. This mechanism is different from the standard treatments for breast cancer, such as hormone therapies like letrozole or CDK4/6 inhibitors like ribociclib, which work by blocking hormone receptors or cell cycle proteins. Researchers are excited about inavolisib because it offers a new way to tackle cancer by directly interfering with a pathway that is often overactive in cancer cells. This could potentially improve outcomes for patients whose cancers are resistant to current therapies.
What evidence suggests that this trial's treatments could be effective for breast cancer?
Research has shown that inavolisib may help treat breast cancer with a PIK3CA mutation. In this trial, participants will receive inavolisib alongside other treatments. Studies have found that combining inavolisib with treatments like palbociclib and fulvestrant can significantly increase survival rates. Specifically, patients who took inavolisib lived for a median of 34 months, compared to 27 months for those on a placebo. Inavolisib reduced the risk of death by more than 30% in some cases. These findings suggest that inavolisib could be an effective treatment option for patients with this type of breast cancer.46789

Trial Overview
The study tests the safety and effectiveness of inavolisib combined with ribociclib and letrozole in treating certain types of breast cancer. It's focused on those who have specific genetic mutations and hormone receptor statuses.
How Is the Trial Designed?
Participants will receive a starting regimen of ribociclib PO QD from Day 1 to 21 and letrozole PO QD from Day 1 to 28 in cycle 1 (each cycle=28 days). Starting on Day 1 of Cycle 2, all participants will receive the triplet regimen inavolisib + ribociclib + letrozole as follows: inavolisib and letrozole PO QD from Day 1 to 28 and ribociclib PO QD from Day 1 to 21 in cycles 2-5 (each cycle=28 days). In cycle 6, inavolisib, ribociclib and letrozole will be administered PO QD on days 1-21 (each cycle=21 days).
Participants will receive a starting regimen of inavolisib and letrozole PO QD from Day 1 to 28 in cycle 1 (each cycle=28 days). Starting on Day 1 of Cycle 2, all participants will receive the triplet regimen inavolisib + ribociclib + letrozole as follows: inavolisib and letrozole PO QD from Day 1 to 28 and ribociclib PO QD from Day 1 to 21 in cycles 2-5 (each cycle=28 days). In cycle 6, inavolisib, ribociclib and letrozole will be administered PO QD on days 1-21 (each cycle=21 days).
Participants will receive inavolisib and letrozole orally (PO) once a day (QD) from Day 1 to 28 and ribociclib PO QD from Day 1 to 21 in cycles 1-5 (each cycle=28 days). In cycle 6, inavolisib, ribociclib and letrozole will be administered PO QD on days 1-21 (each cycle=21 days).
