Researchers are investigating new treatments for untreated advanced non-small cell lung cancer (NSCLC), which is the most common form of lung cancer and lung cancer that has spread beyond surgical removal. Standard treatments include immunotherapy, such as pembrolizumab, and chemotherapy. This study aims to determine the effectiveness of adding other treatments, including the human epidermal growth factor receptor 3-directed antibody-drug conjugate (HER3-DXd) patritumab deruxtecan, to pembrolizumab, with or without chemotherapy. The primary goals are to assess safety and efficacy of the treatments.

Transthyretin amyloidosis (ATTR) is a disease where the normally occurring transthyretin (TTR) protein falls apart and forms amyloid, a sticky plaque- like substance that accumulates in different organs in the body and can cause damage to the organ. There are two ways that the TTR protein can fall apart. One way occurs as a person ages, where the normal TTR protein can fall apart and form amyloid that may no longer be sufficiently cleared by the body. This type of ATTR is known as wild-type ATTR (ATTRwt). The other way occurs when a person inherits a defective TTR gene that causes the TTR protein to spontaneously fall apart. This form of the disease is known as variant ATTR (ATTRv) and can be detected in adults by a genetic test of their TTR gene before they age. Amyloid build-up in the heart causes the heart wall to become thick and stiff and can result in heart failure and even death. Accumulation of TTR amyloid in the heart is known as transthyretin amyloid cardiomyopathy or ATTR-CM. Amyloid can also deposit in the nerve tissues leading to nerve problems. Accumulation of TTR in the nerves is known as transthyretin amyloid polyneuropathy or ATTR-PN. Acoramidis is an experimental drug designed to bind tightly to TTR in the blood and stabilize its structure, so it does not form the harmful amyloid plaques that can cause damage to organs. This study is intended to determine if treatment with acoramidis in participants with ATTRv who have not yet developed any symptoms of disease can prevent or delay the development of ATTR-CM or ATTR-PN disease. If adults with an inherited defective TTR gene are treated early before any of the symptoms of disease have developed, it may be possible to delay the onset or prevent the disease entirely.

This phase II trial compares the effect of atezolizumab in combination with usual treatment with cabozantinib to cabozantinib alone in patients with papillary renal cell carcinoma that has spread from where it first started (primary site) to other places in the body (metastatic). Papillary renal cell carcinoma (PRCC) is a type of kidney cancer that forms in the lining of the tiny tubes in the kidney that return filtered substances that the body needs back to the blood and remove extra fluid and waste as urine. Most papillary tumors look like long, thin finger-like growths under a microscope. It is also called papillary kidney cancer or PRCC. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the tumor and may interfere with the ability of tumor cells to grow and spread. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply and may also prevent the growth of new blood vessels that tumors need to grow. By these actions it may help slow or stop the spread of tumor cells. Combination therapy with atezolizumab and cabozantinib may shrink the tumor and allow a longer survival time in patients with metastatic renal cell carcinoma.

This phase II trial tests whether atezolizumab in combination with selinexor works to shrink tumors in patients with alveolar soft part sarcoma and whether the study drugs are better than the usual approach in treating this type of cancer. The usual approach is defined as care most people get for alveolar soft part sarcoma if they are not part of a clinical study, which includes treatment with radiation, kinase inhibitor drugs, immunotherapy drugs, or chemotherapy drugs. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Selinexor is in a class of medications called selective inhibitors of nuclear export (SINE). It works by blocking a protein called CRM1, which may help keep cancer cells from growing and may kill them. Giving atezolizumab in combination with selinexor may help shrink tumors and stabilize the cancer in patients with alveolar soft part sarcoma.

This phase II trial studies the effect of lutetium Lu 177 dotatate compared to the usual treatment (everolimus) in treating patients with somatostatin receptor positive bronchial neuroendocrine tumors that have spread to other places in the body (advanced). Lutetium Lu 177-dotate is a radioactive drug. It binds to a protein called somatostatin receptor, which is found on some neuroendocrine tumor cells. Lutetium Lu 177-dotatate builds up in these cells and gives off radiation that may kill them. It is a type of radioconjugate and a type of somatostatin analog. Lutetium Lu 177 dotatate may be more effective than everolimus in shrinking or stabilizing advanced bronchial neuroendocrine tumors.

The VA health care system uses a health promotion-focused model which aims to provide longitudinal care through a patient-aligned care team for Veterans with chronic kidney disease. Since the largest subpopulation of Veterans with chronic kidney disease is comprised of those not requiring dialysis, neuromuscular screening assessments may provide valuable information regarding an individual overall health status and potential for future complications. Furthermore, identifying at risk individuals early in the disease process will allow for the prescription of timely interventions. Exercise strategies such as combination exercise, which uses flywheel resistance plus aerobic exercise, may provide a valuable treatment option for combating neuromuscular dysfunction and functional decline in patients with chronic kidney disease.
