Study Summary

This trial is testing whether adding pembrolizumab and/or olaparib to standard radiation therapy can improve outcomes for patients with TNBC.

Who is the study for?
This trial is for women at least 18 years old with metastatic or recurrent triple-negative or hormone-receptor positive/Her2 negative breast cancer. Participants must not be pregnant, breastfeeding, and should follow contraceptive guidance. They need to have stable organ function and performance status (ECOG) of 0-1. Those with HIV, active TB or hepatitis, severe allergies to study drugs, certain previous treatments or conditions that could affect the study's outcome are excluded.Check my eligibility
What is being tested?
The trial tests if adding pembrolizumab (an immunotherapy drug), with or without olaparib (a targeted therapy drug), to standard radiation therapy is more effective for treating metastatic breast cancer than radiation alone. The safety and effectiveness of these combinations are being compared.See study design
What are the potential side effects?
Potential side effects include immune system reactions leading to inflammation in various organs, infusion-related reactions from pembrolizumab; nausea, vomiting, fatigue from olaparib; and skin irritation from radiation. Side effects can vary based on individual patient health.

"That is correct. The clinical trial, which has been recruiting since April 21st 2021, is looking for 34 patients to enroll at 7 different sites."

Answered by AI

How many different research facilities are overseeing this experiment?

"There are 7 primary centres for this study, with Memorial Sloan Kettering Bergen (Limited Protocol Activities) in Montvale, Memorial Sloan Kettering Commack (Limited Protocol Activities) in Commack, and Memorial Sloan Kettering Cancer Center (All Protocol Activities) in New york being a few of them."

When did the FDA last greenlight pembrolizumab?

"Pembrolizumab falls into the Phase 2 category, meaning that while there is some evidence pointing to its safety, there is none yet suggesting that it is an effective treatment. Our team at Power gave it a score of 2."

Answered by AI

Are there Pembrolizumab studies that have been completed in the past?

"1162 clinical trials involving Pembrolizumab are ongoing. Of these, 143 have reached Phase 3 status. The majority of these studies are based out of Houston, Texas; however, there are 43122 different locations running Pembrolizumab trials."
