A Study of Vedolizumab Intravenous (IV) and Adalimumab or Vedolizumab and Ustekinumab in Adults With Crohn's Disease
Recruiting
The main aim of this study is to learn about the effect of treatment with vedolizumab IV (vedolizumab) together with adalimumab or vedolizumab (VDZ) together with ustekinumab (UST) in adults with moderate to severe Crohn's Disease, and the effect of treatment with vedolizumab alone, after the dual targeted treatment. The study is conducted in two parts. In Part A, participants will receive the dual targeted treatment (vedolizumab together with either adalimumab or ustekinumab). In part B, parti... Read More

Disitamab Vedotin With Pembrolizumab vs Chemotherapy in Previously Untreated Urothelial Cancer Expressing HER2
Recruiting
This study will enroll participants with urothelial cancer (UC). UC can include cancer of the bladder, kidney, or the tubes that carry pee through the body (ureter, urethra). This study will try to find out if the drugs disitamab vedotin with pembrolizumab works better than platinum-containing chemotherapy to treat patients with UC. This study will also test what side effects happen when participants take these drugs together. A side effect is anything a drug does to the body besides treating th... Read More

A Trial to Learn How the Cancer Vaccine BNT116 in Combination With Cemiplimab Works and How Safe the Combination is in Adults With Advanced Non-small Cell Lung Cancer (EMPOWERVAX Lung 1)
Recruiting
This study is researching an investigational drug, called BNT116, in combination with cemiplimab. BNT116 and cemiplimab will each be called a "study drug", and together be called "study drugs". The study is focused on patients who have advanced non-small cell lung cancer (NSCLC). The aims of this study are to see how safe and tolerable BNT116 is in combination with cemiplimab and to see how effective BNT116 in combination with cemiplimab is compared to cemiplimab by itself at treating cancer....

A Study of Treatment for Medulloblastoma Using Sodium Thiosulfate to Reduce Hearing Loss
Recruiting
This phase III trial tests two hypotheses in patients with low-risk and average-risk medulloblastoma. Medulloblastoma is a type of cancer that occurs in the back of the brain. The term, risk, refers to the chance of the cancer coming back after treatment. Subjects with low-risk medulloblastoma typically have a lower chance of the cancer coming back than subjects with average-risk medulloblastoma. Although treatment for newly diagnosed average-risk and low-risk medulloblastoma is generally effect... Read More

Thoracotomy Versus Thoracoscopic Management of Pulmonary Metastases in Patients With Osteosarcoma
Recruiting
This phase III trial compares the effect of open thoracic surgery (thoracotomy) to thoracoscopic surgery (video-assisted thoracoscopic surgery or VATS) in treating patients with osteosarcoma that has spread to the lung (pulmonary metastases). Open thoracic surgery is a type of surgery done through a single larger incision (like a large cut) that goes between the ribs, opens up the chest, and removes the cancer. Thoracoscopy is a type of chest surgery where the doctor makes several small incision... Read More

Effect of HSD3B1 (1245C) Gene Mutation on Treatment of Stage I-III Breast Cancer
Recruiting
This stage IV trial examines how a mutation in HSD3B1 (1245C) gene affects treatment of stage I-III breast cancer. This trial may help researchers determine if mutations in HSD3B1 decreases the efficacy of aromatase inhibitor therapy such as letrozole. Letrozole may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
