Clinical trials

Researchers are looking for new ways to treat locally advanced non-small cell lung cancer (NSCLC) that is unresected and has a gene mutation called KRAS G12C. Researchers want to learn if calderasib (MK-1084) can be given with durvalumab, an immunotherapy, to treat NSCLC after chemotherapy and radiation therapy. The goal of this trial is to learn if participants who receive calderasib and durvalumab live longer without the cancer growing or spreading compared to participants who receive placebo and durvalumab.

Researchers are looking for new ways to treat extensive-stage small cell lung cancer (ES-SCLC). ES-SCLC is a type of lung cancer that has spread throughout the lung, to the other lung, or to other parts of the body. A standard (usual) treatment for ES-SCLC uses both chemotherapy and immunotherapy. * Chemotherapy is a treatment that works to destroy cancer cells or stop them from growing. * Immunotherapy is a treatment that helps the immune system fight cancer. Gocatamig and I-DXd (short for ifinatamab deruxtecan) are study medicines. Researchers want to know if giving gocatamig and I-DXd together can treat ES-SCLC. Researchers will also look at giving the study medicines with standard treatment. Gocatamig is a T-cell engager therapy. I-DXd is an antibody drug conjugate. * T-cell engager therapy is a certain type of immunotherapy that uses T-cells to find and destroy cancer cells. * A T-cell is a type of white blood cell, which are cells that help the body fight infection. * An antibody drug conjugate (ADC) is a treatment that attaches to a protein on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn: * About the safety of combining gocatamig and I-DXd and if people tolerate them together * If people who receive gocatamig and I-DXd have ES-SCLC respond, which means the cancer gets smaller or goes away

Researchers are looking for new ways to treat high-risk, localized non-small cell lung cancer (NSCLC) that has been removed with surgery. People with high-risk, localized NSCLC are often treated with surgery. Researchers want to learn if participants can receive 1 or 2 trial treatments to help prevent NSCLC from coming back after surgery. One trial medicine is intismeran (also called V940/mRNA-4157) and the other is subcutaneous pembrolizumab (also called SC pembrolizumab and MK-3475A). Intismeran is designed to help a person's immune system attack their specific cancer. SC pembrolizumab is an immunotherapy treatment which helps the immune system fight cancer. The main purpose of this study is to evaluate whether adjuvant intismeran autogene (V940) in combination with SC pembrolizumab and berahyaluronidase alfa (MK-3475A) or intismeran monotherapy improves disease-free survival (DFS) compared with placebo in participants with completely resected high-risk Stage I NSCLC.

Researchers are looking for new ways to prevent cancers related to human papillomavirus (HPV). HPV is a common virus that can cause an infection. There are many different types of HPV. Most people's immune system can fight HPV infection and it goes away without treatment. For some people, HPV infections can last longer and may cause cancer years later. A standard vaccine to prevent HPV-related cancers is GARDASIL®9 (G9). G9 protects against 9 types of HPV but it does not protect against other types of HPV. The study vaccine (called V540B) is designed to protect against the same HPV types that G9 protects against plus other HPV types. The main goal of this study is to learn about the safety of V540B in healthy adults and if people tolerate it.

Researchers are looking for new ways to treat certain types of advanced solid tumors. Solid tumors are cancers mostly in organs and tissues in the body, not in the blood or other fluids. Advanced means the cancer has spread nearby or to other parts in the body and cannot be removed with surgery. In this trial, researchers want to learn if the trial medicine called MK-2010, given alone or with other treatments, can treat advanced solid tumors. MK-2010 is designed to help the immune system fight cancer. The goals of this trial are to learn: * About the safety of MK-2010 as monotherapy and in combinations and if participants tolerate them. Tolerate means participants will receive trial treatment unless they need to stop it due to health problems. * How many participants who receive MK-2010 as monotherapy and in combination respond to treatment. Respond means the cancer gets smaller or goes away.

Researchers are looking for new ways to treat certain types of advanced solid tumors. Solid tumors are cancers mostly in organs and tissues in the body, not in the blood or other fluids. Advanced may mean the cancer has spread to nearby or other parts of the body. The cancer may not be able to be treated with surgery or radiation, which uses beams of intense energy (like X-rays) to shrink or get rid of tumors. Some cancers may not have gone away or came back after previous treatment. MK-2010, the trial treatment, is designed to help the immune system fight cancer. This trial will look at MK-2010 when given with another trial treatment called sacituzumab tirumotecan (sac-TMT). Sac-TMT is an antibody-drug conjugate (ADC). An ADC attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goals of this trial are to learn: * About the safety of MK-2010 with sac-TMT and if participants tolerate them. Tolerate means participants will receive trial treatment unless they need to stop it due to health problems. * How many participants who receive MK-2010 with sac-TMT have the cancer respond to treatment. Respond means the cancer gets smaller or goes away.

Researchers are looking for new ways to treat people with B-cell cancers. In this trial, researchers will look at chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). These are blood cancers that affect B-cells in the blood, bone marrow, or lymph nodes. The goals of this trial are to learn about: * The safety of MK-1045 and if participants tolerate it. Tolerate means participants will receive trial treatment unless they need to stop treatment due to health problems. * The number of participants who respond. Respond means the number of cancer cells goes down or signs of cancer go away.

Researchers are looking for new ways to treat follicular lymphoma (FL). A standard (usual) treatment for FL includes a targeted therapy called rituximab and chemotherapy. In this study, researchers want to learn if giving a study medicine called MK-1045 and rituximab can treat FL. MK-1045 is a type of treatment called immunotherapy.

MK-1045 is an immunotherapy, which is a treatment that helps the immune system fight cancer. This trial will compare MK-1045 to a standard immunotherapy called blinatumomab. The goals of this trial are to learn if more people who receive MK-1045 have no cancer cells in their bone marrow compared to people who receive blinatumomab and if people who receive MK-1045 live longer compared to people who receive blinatumomab.

Researchers are looking for new ways to treat 2 types of non-Hodgkin lymphoma (NHL) called follicular lymphoma (FL) and diffuse large B-cell lymphoma (DLBCL). FL is a slow-growing type of NHL. DLBCL is a fast-growing type of NHL. NHL is a cancer in the lymphatic system that causes swollen lymph nodes. The lymphatic system is part of the immune system. In this study, researchers want to learn if MK-1045 can treat FL and DLBCL. MK-1045 is a study treatment that is an immunotherapy, which helps the immune system fight cancer. The goals of this study are to learn how safe MK-1045 is and if people tolerate it. Researchers also want to see if FL and DLBCL respond (the cancer gets smaller or goes away) to treatment.

Researchers are looking for other ways to treat metastatic squamous non-small cell lung cancer (NSCLC). Squamous NSCLC is cancer that starts in squamous cells, which are flat cells that line the inside of the airways in the lungs. Metastatic means the cancer has spread to other parts of the body. Standard treatment (usual treatment) for metastatic squamous NSCLC is immunotherapy with or without chemotherapy. Immunotherapy is a treatment that helps the immune system fight cancer. Chemotherapy is medicine that destroys cancer cells or stops them from growing. However, standard treatment may not work or may stop working to treat metastatic squamous NSCLC. Researchers want to learn if study treatments that are antibody drug conjugates (ADCs) can treat metastatic squamous NSCLC that did not respond (get smaller or go away) to standard treatment. An ADC attaches to a protein on cancer cells and delivers treatment to destroy those cells. The main goals of this study are to learn about: * The cancer response to the study treatments compared to chemotherapy * The safety of the study treatments and if people tolerate them This study is one of the substudies being conducted under one pembrolizumab umbrella master protocol (MK-3475-U01/KEYMAKER-U01).

This is a phase 1/2, multicenter, open-label umbrella platform study that will evaluate the safety and tolerability of investigational agents with pembrolizumab and fluoropyrimidine chemotherapy for the first-line (1L) treatment of participants with locally advanced unresectable or metastatic human epidermal growth factor receptor 2 (HER2)-negative gastric, gastroesophageal junction, or esophageal adenocarcinoma. This substudy will have two phases: a safety lead-in phase and an efficacy phase. The safety lead-in phase will be used to evaluate the safety and tolerability, and to establish a recommended Phase 2 dose (RP2D) for investigational agents in combination with chemotherapy and immunotherapy. There is no formal hypothesis in this study.
