Clinical trials

This is a multicentric observational study conducted at selected sites across Latin America. Eligible participants will be identified through the medical records of participating institutions. The study aims to describe overlap of expression of folate receptor alpha (FRα), HER2 and PD-L1 using immunohistochemistry (IHC) and HRD and BRCA (somatic and germline) by NGS. Additionally, to describe clinical demographic and socioeconomic variables, as well as treatment patterns, pathological characteristics, outcomes, and genetic and molecular testing part of clinical practice. All data (including patient characteristics, treatment patterns, outcomes and available tests) will be collected once, retrospectively from medical records, ensuring adherence to ethical standards and participant confidentiality. Biomarkers analysis (including FRα, HER2 and PD-L1) will be performed prospectively, a Formalin-Fixed Paraffin-Embedded (FFPE) tumor block will be collected to evaluate and describe the expression of folate receptor alpha (FRα) and HER2, using immunohistochemistry (IHC) with the Roche Ventana kit (FOLR1 and HER2 4B5) and Dako's 22C3 for PD-L1. The study will analyze samples collected between 1st January 2018 to 31 December 2024 (analysis of historically collected samples). The study comprises a retrospective data collection from medical charts. Participants will continue to receive treatment and clinical evaluations according to what is determined by their medical team, according to the usual standards of treatment and clinical practice of each center. No intervention or prospective follow-up is proposed in this study.

The main aim of this study is to find out how well elritercept works to improve anemia in participants with myelofibrosis (MF) who are taking ruxolitinib when compared to placebo. Other aims are to learn how elritercept improves anemia compared to placebo; to learn if elritercept reduces tiredness, improves symptoms related to MF, and helps participants do physical activities more easily. The study also aims to find out how elritercept affects the bone marrow, the spleen, and whether participants develop antibodies to the study drug. The study will also check how safe elritercept is compared to placebo, and if elritercept stays safe over a long period of time. Participants will receive study treatment for at least 9 months (36 weeks). After this period, participants who received placebo will have the option to switch to elritercept.

The purpose of this protocol is to evaluate the efficacy of MK-8690 in participants with moderately to severely active ulcerative colitis.

The main purpose of this study is to evaluate the safety and effectiveness of LY4268989 when compared to placebo in adult participants with moderately to severely active ulcerative colitis (UC). The study drug will be administered orally. The study will last up to approximately 108 weeks, excluding screening.

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 are looking for more ways to treat PAH. In PAH, the blood vessels in the lungs become thick and narrow, which makes it harder for blood to flow. This causes high blood pressure in the lungs and overworks the heart. PAH can make it hard to breathe and be active. Some standard (usual) treatments for PAH can treat symptoms of PAH but do not stop PAH from getting worse. Sotatercept is a study medicine designed to treat PAH. It is a targeted therapy, which is a treatment that works on certain proteins that play a role in causing PAH. This is a long-term follow-up (LTFU) study. People who took part in certain other studies testing sotatercept for PAH may be able to join this study. The goal of this study is to learn about the long-term safety of sotatercept and if people tolerate it when taken with standard PAH treatment over a longer period of time.

Researchers are looking for new ways to treat metastatic cervical cancer. Cervical cancer is cancer in the cervix, the lower part of the uterus (womb). Metastatic means the cancer has spread to other parts of the body. Researchers want to learn about giving the study medicine sacituzumab tirumotecan (also called sac-TMT or MK-2870) along with pembrolizumab and bevacizumab treatments. Sac-TMT is an antibody drug conjugate, which is a type of medicine that attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn: * About the safety of sac-TMT with pembrolizumab and bevacizumab, and if people tolerate them when given together, and * If people who receive sac-TMT and pembrolizumab, with or without bevacizumab, live longer overall or without their cancer getting worse as compared to those who receive standard treatment

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 new ways to treat radiographic axial spondyloarthritis (r-axSpA). R-axSpA is a type of arthritis that causes pain, stiffness, and inflammation (swelling) in the spine and joints in the pelvis (hip bone). Radiographic means the damage it causes can be seen on X-rays. This study will help find out if a study medicine called tulisokibart can treat symptoms of r-axSpA. Researchers will look at different doses of tulisokibart. Researchers want to know if at least one of the study doses of tulisokibart works better than a placebo to improve r-axSpA symptoms. A placebo looks like the study medicine but has no study medicine in it. Using a placebo helps researchers better understand the effects of the study medicine.

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.

This study is designed to learn if enlicitide decanoate is safe and effective to treat children and adolescents with heterozygous familial hypercholesterolemia (HeFH) and high amounts of low-density lipoprotein cholesterol (LDL-C) in the blood. The goals of this study are to learn about the safety of enlicitide and if children tolerate it, what happens to enlicitide in a child's body over time, and if enlicitide works to lower cholesterol levels in children more than a placebo.

This is a Phase 2b study to evaluate the efficacy and safety of Imeroprubart in adults with CIDP.

Researchers are looking for other ways to treat locally advanced or metastatic colorectal cancer (mCRC) that is unresectable and has a gene mutation called KRAS G12C. Standard (or usual) treatments for this type of colorectal cancer may include mFOLFOX6 with or without bevacizumab. Researchers want to learn if adding calderasib (the study medicine) and cetuximab to mFOLFOX6 can treat locally advanced or mCRC with the KRAS G12C mutation. Calderasib and cetuximab are targeted therapies. The goals of this study are to learn: * About the safety of calderasib with cetuximab and mFOLFOX6 and if people tolerate the treatments * If people who receive calderasib with cetuximab and mFOLFOX6 live longer without mCRC growing or spreading compared to people who receive mFOLFOX6 with or without bevacizumab.

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
