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.

Adults 18 years of age and older or above legal age with lung fibrosis related to systemic autoimmune rheumatic disease can participate in this study. People can only take part if they show no improvement in lung function after standard treatment with immunosuppressant medicine. The main purpose of this study is to find out how a medicine called nerandomilast affects the lungs in people with systemic autoimmune rheumatic disease. Participants are put into 2 groups randomly, which means by chance. One group takes nerandomilast tablets and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Participants take a tablet 2 times a day for at least 26 weeks and up to 1 year. Participants continue immunosuppressant treatment for their underlying rheumatic disease. Participants are in the study for about 7.5 to 13 months depending on when they join the study. During this time, they visit the study site about 9 to 10 times. At study visits, participants have lung function tests. At select visits, chest imaging is performed. Participants fill in questionnaires about their symptoms and quality of life. The results between the 2 groups are compared to see whether the treatment works. The doctors also regularly check participants' health and take note of any unwanted effects.

This phase II trial compares the use of pembrolizumab and radiation therapy to chemotherapy with cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C and radiation therapy for the treatment of non-muscle invasive bladder cancer. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as cisplatin, gemcitabine, 5-fluorouracil or mitomycin-C, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Giving pembrolizumab with radiation may kill more tumor cells than chemotherapy with radiation therapy in patients with non-muscle invasive bladder cancer.

This phase III trial compares standard therapy given after surgery (adjuvant) to standard therapy given before and after surgery (perioperative) in treating patients with stage II-IIIB non-small cell lung cancer (NSCLC) that can be removed by surgery (resectable). The usual approach for patients with resectable NSCLC is chemotherapy and/or immunotherapy before surgery, after surgery, or both before and after surgery. This study is being done to find out which approach is better at treating patients with lung cancer. Treatment will be administered according to the current standard of care at the time of enrollment. Chemotherapy options may include cisplatin, carboplatin, pemetrexed, gemcitabine, docetaxel, and vinorelbine at standard doses according to the treating physician. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of tumor cells. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by stopping cells from using folic acid to make deoxyribonucleic acid (DNA) and may kill tumor cells. Gemcitabine is a chemotherapy drug that blocks the cells from making DNA and may kill tumor cells. Docetaxel is in a class of medications called taxanes. It stops tumor cells from growing and dividing and may kill them. Other chemotherapy drugs, such as vinorelbine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading . Immunotherapy with monoclonal antibodies, such as nivolumab, pembrolizumab, and atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Starting treatment with chemotherapy and immunotherapy prior to surgery and continuing treatment after surgery may be a more effective treatment option than adjuvant therapy alone in patients with stage II-IIIB resectable NSCLC.

This phase III trial compares the effect of continuation of treatment with pembrolizumab (usual approach) to observation only at preventing cancer from coming back in patients with early-stage triple-negative breast cancer (TNBC) who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. The usual approach for patients with early-stage TNBC who receive preoperative chemotherapy plus pembrolizumab is to continue to receive pembrolizumab for up to 27 weeks after surgery. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help researchers determine if observation is as good as receiving pembrolizumab for 27 weeks after surgery in triple-negative breast cancer patients who achieved a pathologic complete response after preoperative treatment with chemotherapy and pembrolizumab.

Claudin 18.2 protein, or CLDN18.2 is a protein found on cells in the digestive system. It is also found on some tumors. Researchers are looking at ways to attack CLDN18.2 to help control tumors. ASP2138 is thought to bind to CLDN18.2 and a protein on a type of immune cell called a T-cell. This "tells" the immune system to attack the tumor. ASP2138 is a potential treatment for people with stomach cancer, gastroesophageal junction cancer (GEJ cancer) or pancreatic cancer. GEJ is where the tube that carries food (esophagus) joins the stomach. Before ASP2138 is available as a treatment, the researchers need to understand how it is processed by and acts upon the body. In this study, ASP2138 will either be given by itself, or given together with standard treatments for gastric, GEJ and pancreatic cancer. Pembrolizumab and mFOLFOX6, and ramucirumab and paclitaxel are standard treatments for gastric and GEJ cancer. mFOLFIRINOX is a standard treatment for pancreatic cancer. This information will help find a suitable dose of ASP2138 given by itself and together with the standard cancer treatments and to check for potential medical problems from the treatments. The main aims of the study are: - To check the safety of ASP2138 and how well people can tolerate medical problems during the study. - To find a suitable dose of ASP2138 to be used later in the study. - These are done for ASP2138 given by itself and when given together with the standard cancer treatments. Adults 18 years or older with stomach cancer, GEJ cancer, or pancreatic cancer can take part. Their cancer is locally advanced unresectable or metastatic. Locally advanced means the cancer has spread to nearby tissue. Unresectable means the cancer cannot be removed by surgery. Metastatic means the cancer has spread to other parts of the body. There should also be the CLDN18.2 marker in a tumor sample. People cannot take part if they need to take medicines to suppress their immune system, have blockages or bleeding in their gut, have specific uncontrollable cancers, have specific infections, have a condition such as hemophagocytic lymphohistiocytosis (HLH) which is when the body over-reacts to a "trigger" such as infection, or have a specific heart condition ("New York Heart Association Class III or IV"). Phase 1: Lower to higher doses of ASP2138 - ASP2138 is either given through a vein (intravenous infusion) or just under the skin (subcutaneous injection). - Different small groups are given lower to higher doses of ASAP2138. - ASP2138 is either given by itself, or given with 1 of 3 standard treatments: - Pembrolizumab and mFOLFOX6 (first treatment for gastric GEJ cancer) - Ramacirumab and paclitaxel (Second treatment for gastric or GEJ cancer) - ASP2138 with mFOLFIRINOX (first treatment for pancreatic cancer) Phase 1b: doses of ASP2138 worked out from Phase 1 - ASP2138 is either given through a vein or just under the skin. This depends on the findings from Phase 1. - People with gastric cancer, GEJ cancer or pancreatic cancer are given doses of ASP2138, worked out from Phase 1. - This includes doses of ASP2138 given by itself and ASP2138 given with the standard cancer treatments. - The standard cancer treatments given depends on the type of cancer they have. End of treatment visit: This is 7 days after final dose of study treatment or if the study doctor decides to stop the person's treatment. People who have locally advanced unresectable pancreatic cancer will not receive ASP2138 by itself.
