Study of Pembrolizumab With Concurrent Chemoradiation Therapy Followed by Pembrolizumab With or Without Olaparib in Stage III Non-Small Cell Lung Cancer (NSCLC) (MK-7339-012/KEYLYNK-012)

United States, Argentina, Canada870 participantsStarted 2020-07-06

Plain-language summary

The purpose of this study is to assess the efficacy and safety of pembrolizumab in combination with concurrent chemoradiation therapy followed by either pembrolizumab with olaparib placebo (Arm 1) or with olaparib (Arm 2) compared to concurrent chemoradiation therapy followed by durvalumab (Arm 3) in participants with unresectable, locally advanced NSCLC. Arms 1 and 2 will be studied in a double-blind design and Arm 3 will be open-label. The primary hypotheses are: 1. Pembrolizumab with concurrent chemoradiation therapy followed by pembrolizumab with olaparib is superior to concurrent chemoradiation therapy followed by durvalumab with respect to progression-free survival (PFS) and overall survival (OS) 2. Pembrolizumab with concurrent chemoradiation therapy followed by pembrolizumab is superior to concurrent chemoradiation therapy followed by durvalumab with respect to PFS and OS

Inclusion Criteria: * Has pathologically (histologically or cytologically) confirmed diagnosis of NSCLC * Has Stage IIIA, IIIB, or IIIC NSCLC by American Joint Committee on Cancer Version 8 * Is unable to undergo surgery with curative intent for Stage III NSCLC * Has no evidence of metastatic disease indicating Stage IV NSCLC * Has measurable disease as defined by RECIST 1.1 * Has not received prior treatment (chemotherapy, targeted therapy or radiotherapy) for Stage III NSCLC; participants who have received neoadjuvant and/or adjuvant therapy for early stage disease are not eligible * Has provided a tumor tissue sample (tissue biopsy \[core, incisional, or excisional\]) * Has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1 assessed within 7 days prior to the first administration of study intervention * Has a life expectancy of at least 6 months * A male participant must agree to use contraception and refrain from donating sperm during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention unless confirmed to be azoospermic (vasectomized or secondary to medical cause). The length of time required to continue contraception for each study intervention is as follows: Olaparib, platinum doublet, and radiotherapy: 90 days * A female participant is eligible to participate if she is not pregnant, not breastfeeding, and agrees to use contraception and refrain from donating eggs…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
