Testing the Addition of Anti-Cancer Drug, Cetuximab, to Standard of Care Treatment (Pembrolizumab) for Returning or Spreading Head and Neck Cancer After Previous Treatment
Recruiting
This phase III trial compares the effect of adding cetuximab to pembrolizumab versus pembrolizumab alone in treating patients with head and neck squamous cell carcinoma (HNSCC) that has come back after a period of improvement (recurrent) and/or that has spread from where it first started (primary site) to other places in the body (metastatic). Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This... Read More

A Study to Compare Sacituzumab Tirumotecan (MK-2870) Monotherapy Versus Treatment of Physician's Choice as Second-line Treatment for Participants With Recurrent or Metastatic Cervical Cancer (MK-2870-020/TroFuse-020/Gog-3101/ENGOT-cx20)
Recruiting
This study will have two phases: a sacituzumab tirumotecan safety run-in and a Phase 3 portion. The safety run-in phase will be used to evaluate the efficacy and safety of sacituzumab tirumotecan at the dose for evaluation in the Phase 3 portion. The purpose of this study is to compare the efficacy and safety of sacituzumab tirumotecan versus treatment of physician's choice as second-line treatment for participants with recurrent or metastatic cervical cancer in the Phase 3 portion.

Bomedemstat vs Hydroxyurea for Essential Thrombocythemia (MK-3543-007)
Recruiting
The purpose of this study is to evaluate the efficacy and safety of bomedemstat compared with hydroxyurea in cytoreductive therapy naïve essential thrombocythemia (ET) participants for whom cytoreductive therapy is indicated. Its primary objective is to compare bomedemstat to hydroxyurea with respect to durable clinicohematologic response (DCHR). The primary hypothesis is that bomedemstat is superior to hydroxyurea with respect to DCHR.

Pembrolizumab Plus CA-4948 for the Treatment of Patients With Progressive Metastatic Urothelial Cancer Despite Prior Immunotherapy
Recruiting
This phase I trial tests the safety, side effects, best dose, and effectiveness of emavusertib (CA-4948) in combination with pembrolizumab in treating patients with urothelial cancer that has spread from where it first started to other places in the body (metastatic) and that has a resistance to PD-1/PD-L1 immune checkpoint inhibitors. CA-4948, a kinase inhibitor, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies,... Read More

A Clinical Study of MK-2870 Alone or With Chemotherapy to Treat Gastrointestinal Cancers (MK-9999-02A)
Recruiting
Researchers want to learn if sacituzumab tirumotecan (MK-2870) alone or with chemotherapy can treat certain gastrointestinal (GI) cancers. The GI cancers being studied are either advanced (the cancer has spread to other parts of the body), or unresectable (the cancer cannot be removed with surgery). The goals of this study are to learn: * About the safety and how well people tolerate sacituzumab tirumotecan alone or with chemotherapy * How many people have the cancer respond (get smaller or go...
