Trial Summary

What is the purpose of this trial?

This trial is testing a new treatment that combines two medications to see if it works better than the current treatment for serious cancers, particularly cervical cancer. One of the medications has shown promising results in treating various cancers, including cervical cancer. The goal is to find out if this combination can improve patient outcomes by helping the immune system fight cancer more effectively.

Treatment Details

Interventions

• Pembrolizumab
• Pembrolizumab/Vibostolimab Co-Formulation

Trial Overview The study tests the safety and effectiveness of a drug combo called pembrolizumab/vibostolimab (MK-7684A), alone or with other cancer therapies. It aims to see if this combination works better than pembrolizumab alone in treating participants with cervical cancer by looking at response rates and survival without progression.
