Clinical trials

This is a Ph 2, randomized, double-blind, placebo-controlled global multicenter study to evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of PIPE-791 in participants with a diagnosis of Idiopathic Pulmonary Fibrosis (IPF) with or without background treatment.

Background: Autoimmune diseases can be caused by genes people inherit from their parents. The gene changes that cause these diseases have been well studied in people with European and Asian ancestors. But some diseases behave differently in people who are native to North and South America. Researchers want to know more about the gene changes and other factors that may cause autoimmune diseases among these people. This project will be based in Peru. Objective: To study how gene changes can lead to autoimmune diseases in people native to Peru. Eligibility: People aged 18 years and older with an autoimmune disease. These may include systemic lupus erythematosus; Sjogren disease; scleroderma; rheumatoid arthritis; seronegative spondylo-arthropathies; and systemic vasculitis. Family members and healthy volunteers are also needed. Design: Participants will have 2 clinic visits; these will be 2 weeks apart. The clinics will be in Lima, Iquitos, and other sites in Peru. Visit 1: Participants will have a physical exam. They will answer questions about their health risks and habits. They will provide blood and urine samples. Visit 2: Participants will provide a second blood sample and a stool sample. They will talk about the results of their first clinical exam with researchers. The cost of travel to and from the clinics will be provided. Participants will get $30 per visit and a snack.

A Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel Group, Phase 3 Study to Evaluate the Efficacy and Safety of Tezepelumab in Adults with Moderate to Very Severe Chronic Obstructive Pulmonary Disease (COPD)

Researchers want to learn if the study medicines calderasib and subcutaneous (SC) pembrolizumab can be used to treat non-small cell lung cancer (NSCLC) when given together. Calderasib is a targeted therapy for the KRAS G12C mutation. The goal of this study is to learn if people who receive calderasib with SC pembrolizumab live longer without the cancer growing or spreading than in people who receive SC pembrolizumab with chemotherapy.

Researchers are looking for other ways to treat breast cancer (BC) that is hormone receptor-positive and human epidermal growth factor receptor 2-negative (HR+/HER2-) and either unresectable locally advanced or metastatic. * HR positive (HR+) means the cancer cells have proteins that attach to estrogen or progesterone (hormones) which help the cancer to grow and spread * HER2 negative (HER2-) means the cancer cells have a low amount of a protein called HER2 * Unresectable locally advanced means the cancer cannot be completely removed by surgery and has spread into nearby tissue or muscles * Metastatic means the cancer has spread to other parts of the body Treatment for this type of breast cancer usually includes endocrine therapy (ET) and sometimes a second treatment. The main goal of this study is to learn if people who receive patritumab deruxtecan (also known as HER3-DXd and MK-1022) live longer overall or without the cancer growing/spreading, compared to people who receive chemotherapy or a different drug called trastuzumab deruxtecan.

Researchers are looking for new ways to treat metastatic castration-resistant prostate cancer (mCRPC). Researchers have designed a study medicine called ifinatamab deruxtecan (also called I-DXd or MK-2400) to treat mCRPC. The goal of this study is to learn if people who receive I-DXd live longer overall and live longer without the cancer growing or spreading than people who receive chemotherapy.

This is a study evaluating the efficacy and safety of calderasib with pembrolizumab as first-line treatment in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) with identified Kirsten rat sarcoma viral oncogene homolog G12C (KRAS G12C) mutation and programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%. There is one primary study hypothesis: Combination of calderasib and pembrolizumab is superior to placebo plus pembrolizumab with respect to progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).

The purpose of this Phase 2/3, randomized, multisite, open-label, dose confirmation, and expansion study is to evaluate the safety, and efficacy of zilovertamab vedotin (ZV) in combination with standard of care options for the treatment of rrDLBCL. This study will be divided into 2 parts: Dose Confirmation (Part 1) and Efficacy Expansion (Part 2) and will enroll participants who are at least 18 years of age with rrDLBCL. The hypotheses are: ZV in combination with rituximab, gemcitabine, and oxaliplatin (R-GemOx) is superior to R-GemOx with respect to progression-free survival (PFS) per Lugano response criteria by blinded independent review committee (BICR); and that ZV in combination with bendamustine rituximab (BR) is superior to BR with respect to PFS per Lugano response criteria by BICR. With protocol amendment 4 (effective: 04-April-2024), enrollment in Cohort B (study arms Bendamustine Rituximab \[BR\] and ZV + BR) is discontinued. No efficacy outcome analysis and hypothesis testing will be conducted for Cohort B.

The purpose of this study is to evaluate the long-term safety and efficacy of pembrolizumab (MK-3475) in participants from previous Merck pembrolizumab-based parent studies who transition into this extension study. This study will consist of three phases: 1) First Course Phase, 2) Survival Follow-up Phase or 3) Second Course Phase. Each participant will transition to this extension study in one of the following three phases, depending on the study phase they were in at the completion of the parent study. Participants who were in the First Course Phase of study treatment with pembrolizumab or lenvatinib in their parent study will enter the First Course Phase of this study and complete up to 35 doses or more every 3 weeks (Q3W) or 17 doses or more every 6 weeks (Q6W) of study treatment with pembrolizumab or a pembrolizumab-based combination or lenvatinib according to arm assignment. Participants who were in the Follow-up Phase in the parent study (post-treatment or Survival Follow-up Phase) will enter the Survival Follow-up Phase of this study. Participants who were in the Second Course Phase in their parent study will enter Second Course Phase of this study and complete up to 17 doses Q3W or 8 doses Q6W of study treatment with pembrolizumab or a pembrolizumab-based combination according to arm assignment. Any participant originating from a parent trial where crossover to pembrolizumab was permitted upon disease progression may be eligible for 35 doses as Q3W or 17 doses Q6W of pembrolizumab (approximately 2 years), if they progress while on the control arm and pembrolizumab is approved for the indication in the country where the potential eligible crossover participant is being evaluated.

The main aim of this study is to find out how well elritercept works in lowering the need for RBC transfusions. Other aims are to learn how well elritercept works in reducing the need for RBC transfusions over longer periods of time or in adults with high transfusion needs. The study will also check on how safe elritercept is and how well it is tolerated.

This phase II, randomized, double-blind, placebo-controlled study is designed to evaluate the safety, efficacy and pharmacokinetics (PK) of obinutuzumab in adolescent participants (AP) aged 12 to less than 18 with biopsy-confirmed proliferative lupus nephritis (LN). It will also evaluate open label safety and PK of obinutuzumab in pediatric participants (PP), aged 5 to \<12 with LN.

Researchers are looking for new ways to treat ovarian cancer (OC). Current treatment for OC may start with surgery to remove as much of the cancer as possible. After surgery, people may receive chemotherapy. After chemotherapy, standard care options may include: * Maintenance treatment, which is used after another therapy to keep the cancer from growing, spreading, or coming back. Bevacizumab is a targeted therapy used as standard maintenance treatment. Targeted therapy works to control how specific types of cancer cells grow and spread. * Observation, which is watching to see if cancer grows or worsens The study medicine, sacituzumab tirumotecan (also called sac-TMT), is a targeted therapy. The goal of this study is to learn if people who receive sac-TMT maintenance treatment with or without bevacizumab live longer without the cancer getting worse than people who receive standard care.

Researchers want to learn if MK-5684 (the study medicine) can treat breast cancer, ovarian cancer, and endometrial cancer. MK-5684, the study medicine, is designed to treat cancer by blocking the body from making steroid hormones. Researchers will compare MK-5684 to the standard treatments for each cancer type in this study. The goal of this study is to learn if people who receive MK-5684 live longer without the cancer growing or spreading compared to people who receive a standard treatment.

Researchers are looking for new ways to treat types of breast cancer that are both: * High-risk, which means the cancer may have a higher chance of getting worse or coming back after treatment * Early-stage, which means the cancer is in the breast or the lymph nodes around the breast The 2 types of breast cancer in this study are triple-negative breast cancer (TNBC) and hormone receptor (HR)-low positive/human epidermal growth factor receptor-2 (HER2) negative breast cancer. These cancers have zero or a low amount of a protein called HER2 and other proteins that attach to the hormones estrogen or progesterone. Sacituzumab tirumotecan (also known as sac-TMT or MK-2870), the study medicine, is a type of targeted therapy. A targeted therapy is a treatment that works to control how specific types of cancer cells grow and spread. The main goals of this study are to learn if people who receive sac-TMT, pembrolizumab, and chemotherapy: * Have fewer cancer cells found in the tumors and lymph nodes removed during surgery compared to those who receive only pembrolizumab and chemotherapy * Live longer without the cancer growing, spreading, or coming back compared to people who receive only pembrolizumab with chemotherapy

Researchers are looking for new ways to treat people with proficient mismatch repair (pMMR) endometrial cancer (EC) that is advanced or recurrent. * EC is a type of cancer that starts in the tissues inside the uterus (womb) * pMMR indicates that certain normal proteins are present in the cancer cells * Advanced means the cancer has spread locally or to other parts of the body (metastatic) and cannot be removed with surgery * Recurrent means the cancer came back after surgery Sacituzumab tirumotecan (also known as sac-TMT) and pembrolizumab are the study medicines. 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 goal of this study is to learn if people who receive sac-TMT with pembrolizumab live longer and without the cancer getting worse compared to people who receive pembrolizumab alone.

Researchers want to know if sacituzumab tirumotecan given alone or with pembrolizumab can treat triple negative breast cancer (TNBC). The main goal of this study is to learn if people treated with sacituzumab tirumotecan alone or with pembrolizumab live longer overall or without the cancer growing or spreading compared to people treated with chemotherapy.

The main goals of this study are to learn about the safety of sacituzumab tirumotecan with bevacizumab and if people tolerate it; and if people who take sacituzumab tirumotecan with or without bevacizumab live longer without the cancer getting worse than those who receive standard of care treatment.

Researchers are looking for other ways to prevent severe illness from COVID-19. COVID-19 is a virus that most often causes mild flu or cold-like symptoms. However, people with certain health conditions or other factors have a high risk (chance) of getting severely ill from COVID-19, which can require a hospital stay or lead to death. Some people who are high risk for severe illness may be unable to take certain treatments for COVID-19 because they are not available to them, or they take other medicines that may react with a treatment and cause an unwanted effect. Molnupiravir (MK-4482) is a study medicine designed to stop the COVID-19 virus from copying itself in the body (multiplying). The goal of this study is to learn if molnupiravir prevents severe illness from COVID-19 more than placebo in people who are high risk.

This is a phase 3 study of pembrolizumab in combination with carboplatin/taxane (paclitaxel or nab-paclitaxel) followed by pembrolizumab with or without maintenance sacituzumab tirumotecan (sac-TMT; MK-2870) in first-line treatment of metastatic squamous non-small cell lung cancer. It is hypothesized that pembrolizumab with maintenance sacituzumab tirumotecan is superior to pembrolizumab without sacituzumab tirumotecan maintenance with respect to overall survival (OS).

The purpose of this study is to compare sacituzumab tirumotecan as a single agent, and in combination with pembrolizumab, versus Treatment of Physician's Choice (TPC) in participants with hormone receptor positive/human epidermal growth factor receptor-2 negative (HR+/HER2-) unresectable locally advanced, or metastatic, breast cancer. The primary hypotheses are that sacituzumab tirumotecan as a single agent and sacituzumab tirumotecan plus pembrolizumab are superior to TPC with respect to progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) by blinded independent central review (BICR) in all participants.

The purpose of this study is to assess the efficacy and safety of opevesostat plus daily corticosteroids compared to alternative abiraterone acetate or enzalutamide in participants with Metastatic Castration-resistant Prostate Cancer (mCRPC) previously treated with one next-generation hormonal agent (NHA). The primary study hypothesis is that opevesostat is superior to alternative abiraterone acetate or enzalutamide with respect to overall survival (OS), in androgen receptor ligand binding domain (AR LBD) mutation positive and negative participants.

This is a phase 3, randomized, open-label study of opevesostat compared to alternative abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer (mCRPC) with respect to overall survival (OS) in participants with mCRPC previously treated with next-generation hormonal agent (NHA) and taxane-based chemotherapy. It is hypothesized that opevesostat is superior with respect to OS in androgen receptor ligand binding domain (AR LBD) mutation-negative and -positive participants.

The goal of this study is to learn if people who receive intismeran autogene and pembrolizumab after surgery are cancer-free longer than people who receive placebo and pembrolizumab. Researchers want to know if giving intismeran autogene and pembrolizumab after surgery can help prevent the cancer from coming back in people with non-small cell lung cancer (NSCLC) whose tumors did not respond completely to treatment before surgery (neoadjuvant treatment).

The purpose of this study is to evaluate the ability of dapirolizumab pegol (DZP) as an add-on treatment to standard of care (SOC) medication to achieve clinically relevant long term improvement of moderate to severe disease activity.

The purpose of this protocol is to evaluate the efficacy and safety of tulisokibart in participants with moderately to severely active Crohn's disease. Study 1's primary hypotheses are that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or per stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 52 (US/FDA and EU/EMA), and that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or per stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 12 (US/FDA and EU/EMA). Study 2's primary hypothesis is that at least 1 tulisokibart dose level is superior to placebo in the proportion of participants achieving clinical remission per Crohn's Disease Activity Index score (\<150, US/FDA) or stool frequency and abdominal pain score (EU/EMA) and in the proportion of participants achieving endoscopic response at Week 12 (US/FDA and EU/EMA).
