Study Summary

This trial will compare the efficacy of three different treatments for unresectable, locally advanced NSCLC. Arm 1 will receive pembrolizumab concurrently with chemoradiation, followed by pembrolizumab with olaparib placebo. Arm 2 will receive the same treatment as Arm 1, but will take olaparib instead of the placebo. Arm 3 will receive concurrent chemoradiation therapy followed by durvalumab. The primary hypothesis is that pembrolizumab with concurrent chemoradiation and olaparib is superior to durvalumab with respect to PFS and OS.

Who is the study for?
This trial is for adults with Stage III NSCLC who haven't had previous treatments for this stage, can't have surgery to cure it, and don’t have metastatic (Stage IV) disease. They should be expected to live at least 6 months, able to perform daily activities with little or no help (ECOG 0-1), and must agree to use contraception.Check my eligibility
What is being tested?
The study tests pembrolizumab combined with chemoradiation followed by either pembrolizumab plus olaparib placebo or just olaparib versus chemoradiation followed by durvalumab. It aims to see if the first two methods are better than the third in improving survival without cancer progression.See study design
What are the potential side effects?
Possible side effects include immune system reactions affecting organs, infusion-related reactions, fatigue, nausea, blood cell changes increasing infection risk. Specifics depend on each drug combination but may also involve lung issues like pneumonitis.

What are some of the conditions that Pembrolizumab is used to manage?

"Pembrolizumab is the standard medication for melanoma. Pembrolizumab can also be used to treat neoplasm metastasis, malignant melanoma of skin, and merkel cell cancer."

Answered by AI

What other medical studies have there been with Pembrolizumab?

"Pembrolizumab was first trialed in 1997 by City of Hope Comprehensive Cancer Center. 3012 trials have completed since then and as of now, 2916 are actively ongoing. A large number clinical trials for this medication are based out of Fullerton, Indiana."

Answered by AI

What are the risks of Pembrolizumab for patients?

"Pembrolizumab has received a score of 3 for safety. This rating comes from the fact that there is some efficacy data as well as multiple rounds of safety data because it is in Phase 3 clinical trials."

Answered by AI

Would it be possible to find out how many different health care facilities are running this research project in town?

"This study is currently running at St Joseph Heritage Healthcare-Oncology ( Site 0088) in Fullerton, Franciscan St. Francis Health ( Site 0031) in Lafayette, and Rutgers Cancer Institute of New jersey ( Site 0054) in New Brunswick as well as 30 other locations."

Answered by AI

Why was this clinical trial designed, and what are its goals?

"The sponsor of the study, Merck Sharp & Dohme LLC, reports that the primary outcome will be Overall Survival (OS), which will be measured over a time frame of Up to approximately 48 months. Additionally, this trial will assess secondary outcomes including Change from Baseline in Role Functioning Using the EORTC QLQ-C30 Items 6-7 Score, Discontinuation Rate of Study Intervention Due to an Adverse Event (AE), and TTD in Cough Using the EOTRC QLQ-LC13 Item 1 Score."
