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.

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.

A Study of Atezolizumab Plus Bevacizumab Versus Active Surveillance as Adjuvant Therapy in Patients With Hepatocellular Carcinoma at High Risk of Recurrence After Surgical Resection or Ablation
This study is looking at a new treatment for liver cancer to stop it coming back after surgery or other procedures. It compares two drugs, atezolizumab and bevacizumab, with regular check-ups to see which is better at preventing the cancer from returning.
