Study Summary

This trial is studying two different ways to give pembrolizumab (with or without stereotactic body radiation therapy) to see how well it works in treating patients with Merkel cell cancer that has spread to other places in the body.

Who is the study for?
This trial is for adults with advanced Merkel Cell Carcinoma (MCC) who are in fairly good health, as shown by their ECOG status and normal organ function tests. They must have at least two cancerous deposits suitable for the study treatments and cannot be pregnant or nursing. People with HIV can join if they meet certain health criteria.Check my eligibility
What is being tested?
The trial is testing whether adding Stereotactic Body Radiation Therapy to Pembrolizumab, an immunotherapy drug, improves outcomes in patients with MCC. Participants will either receive just Pembrolizumab or both treatments together to see which works better.See study design
What are the potential side effects?
Pembrolizumab may cause immune-related side effects like inflammation of organs, fatigue, skin reactions, and flu-like symptoms. The radiation therapy could lead to localized skin irritation and damage to nearby tissues or organs.

Frequently Asked Questions

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

What therapeutic applications has Pembrolizumab demonstrated efficacy for?

"Pembrolizumab is recognized for its efficacy in treating malignant neoplasms, unresectable melanoma, and cases of high microsatellite instability."

Answered by AI

Are there any establishments conducting this clinical study in North America?

"This clinical trial is being held at Minnesota Oncology Hematology PA-Maplewood in Maplewood, Saint John's Hospital - Healtheast in Lexington, and Saint Joseph Radiation Oncology Resource Center in Ballwin, as well as 100 different other medical sites."

Answered by AI

How many participants are currently receiving treatment as part of this clinical research?

"This clinical trial has stopped accepting participants, as the last edit was made on December 3rd 2022. Fortunately, there are still 2484 studies recruiting for Merkel cell carcinoma and 961 for Pembrolizumab."

Answered by AI

What prior investigations have included Pembrolizumab as part of the research?

"Currently, 961 clinical trials concerning Pembrolizumab are underway; of that total number, 122 are in the final stage. Most of those tests take place in Houston but there are 36177 other sites carrying out these experiments."

Answered by AI

Are researchers presently welcoming new participants for this trial?

"This trial is not presently enrolling new participants. First posted on February 1st, 2018 and most recently updated on December 3rd 2022, it has since ceased its recruitment efforts for the time being. For those seeking alternatives studies involving merkel cell carcinoma there are 2484 clinical trials actively recruiting patients, with 961 of these focusing specifically on Pembrolizumab treatments."

Answered by AI

Has the FDA given sanction to Pembrolizumab?

"There is some evidence to suggest that pembrolizumab may be safe, so it was assigned a score of 2. However, there are no clinical findings currently available regarding the efficacy of this medication."
