Study Summary

This trial will see if a new cancer treatment is better than current treatments. The new treatment is pembrolizumab (MK-3475) given before and after surgery for people with resectable stage II, IIIA, and resectable IIIB (T3-4N2) non-small cell lung cancer (NSCLC).

Who is the study for?
This trial is for adults with untreated, resectable Stage II-III NSCLC. Participants must have good organ function and performance status (ECOG 0-1), agree to contraception guidelines, and provide a tumor tissue sample. Exclusions include HIV, prior cancer treatments for the current malignancy, certain lung cancer types, severe allergies to study drugs or their components, active autoimmune diseases requiring treatment in the past 2 years, other health conditions that could affect participation or trial results.Check my eligibility
What is being tested?
The trial tests pembrolizumab combined with platinum doublet chemotherapy before surgery (neoadjuvant phase) and pembrolizumab alone after surgery (adjuvant phase). It aims to improve event-free survival and overall survival compared to placebo. Patients are randomly assigned to receive either pembrolizumab or placebo alongside standard chemotherapy before and after surgical removal of the lung tumor.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects such as inflammation in various organs including lungs (pneumonitis), liver problems, skin reactions, hormone gland issues like thyroid disorders; also possible are infusion reactions during drug administration. Chemotherapy can lead to nausea/vomiting, hair loss, fatigue and increased risk of infections.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is Pembrolizumab commonly given as a treatment for other conditions?

"Pembrolizumab is the standard course of treatment for refractory, relapsed mediastinal large b-cell lymphoma. In addition, Pembrolizumab has shown to be effective in treating other cancers like urinary bladder, advanced testicular cancer, and small cell lung cancer (sclc)."

Answered by AI

Could you please tell us if Pembrolizumab has been used in other research trials?

"Pembrolizumab is being studied in 443 Phase 3 trials out of a total of 1960 ongoing investigations. The global distribution of these trials is significant, with 79276 centres running pembrolizumab studies. However, the largest concentration of these trials is in Shanghai, China."

Answered by AI

In how many places can patients volunteer for this research?

"prospective patients can consult the full list of 33 clinical trial sites, but a few notable locations include McGill University Health Centre (Site 0111) in Montreal, Quebec, Memorial Sloan Kettering Cancer Center - Nassau (Site 0078) in Uniondale, New york, and OHSU Center for Health & Healing (Site 1006) in Portland, Oregon."
