Evaluation of Co-formulated Pembrolizumab/Quavonlimab (MK-1308A) Versus Other Treatments in Participants With Microsatellite Instability-High (MSI-H) or Mismatch Repair Deficient (dMMR) Stage IV Colorectal Cancer (CRC) (MK-1308A-008/KEYSTEP-008)
This study looks at new drug combinations for advanced bowel cancer that has specific genetic markers (MSI-H or dMMR). It compares these combinations with existing treatments to see if they are more effective and safe for patients.

A Study of Opevesostat (MK-5684) Versus Alternative Next-generation Hormonal Agent (NHA) in Metastatic Castration-resistant Prostate Cancer (mCRPC) Post One NHA (MK-5684-004)
This study compares a new medicine, opevesostat, with existing treatments like abiraterone or enzalutamide for prostate cancer that has spread and is no longer responding well to standard hormone therapy. It aims to see if opevesostat is safer and more effective at stopping cancer growth.

Efficacy and Safety of Pembrolizumab (MK-3475) in Combination With Bacillus Calmette-Guerin (BCG) in High-Risk Non-Muscle Invasive Bladder Cancer (HR NMIBC) (MK-3475-676/KEYNOTE-676)
This study is looking into a new treatment for a type of bladder cancer called high-risk non-muscle invasive bladder cancer. It combines a drug called pembrolizumab with an existing treatment, BCG, to see if it works better and is safe.

A Study of Atezolizumab With Lenvatinib or Sorafenib Versus Lenvatinib or Sorafenib Alone in Hepatocellular Carcinoma Previously Treated With Atezolizumab and Bevacizumab
This study looks at new drug combinations for advanced liver cancer that has already been treated. It compares atezolizumab with lenvatinib or sorafenib against lenvatinib or sorafenib alone, to see if the combinations work better and are safe.

Study of Pembrolizumab (MK-3475) Versus Placebo in Combination With Neoadjuvant Chemotherapy & Adjuvant Endocrine Therapy in the Treatment of Early-Stage Estrogen Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative (ER+/HER2-) Breast Cancer (MK-3475-756/KEYNOTE-756)
This study looks at a new drug, pembrolizumab, for early-stage breast cancer. It's for people with a specific type of breast cancer (ER+/HER2-). Researchers want to see if adding pembrolizumab to standard chemotherapy and hormone therapy works better than standard treatment alone.

A Global Phase III Study of Rilvegostomig or Pembrolizumab Monotherapy for First-Line Treatment of PD-L1-high Metastatic Non-small Cell Lung Cancer
This study is testing a new drug, rilvegostomig, against a standard treatment, pembrolizumab, for advanced lung cancer. It's for people whose cancer has spread and has high levels of a specific marker called PD-L1. The aim is to see which treatment works better and is safer.

Efficacy and Safety of Pembrolizumab (MK-3475) Plus Lenvatinib (E7080/MK-7902) Plus Chemotherapy in Participants With Metastatic Esophageal Carcinoma (MK-7902-014/E7080-G000-320/LEAP-014)
This study tested new drug combinations for advanced oesophageal cancer. It looked at pembrolizumab with lenvatinib and chemotherapy, versus pembrolizumab and chemotherapy, to see which worked best and was safest. The study has now stopped, with no safety concerns being the reason.

A Study of Sacituzumab Tirumotecan (MK-2870) as a Single Agent and in Combination With Pembrolizumab (MK-3475) Versus Treatment of Physician's Choice in Participants With HR+/HER2- Unresectable Locally Advanced or Metastatic Breast Cancer (MK-2870-010)
This study is for people with advanced HR+/HER2- breast cancer. It compares a new drug, sacituzumab tirumotecan (alone or with pembrolizumab), against standard chemotherapy, to see which treatment best controls the cancer's growth.
