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.

The project is a placebo-controlled study that aims to use closed-loop transcranial alternating current stimulation (tACS) to study patients with symptoms of mild cognitive impairment which is likely due to Alzheimer's disease or another form of dementia (AD-MCI). Patients will undergo an EEG and complete some questionnaires and computer tasks during each study visit. The project has the following aims and hypotheses: 1.) To determine the impact of closed-loop 40 Hz tACS on the entrainment of natural gamma rhythms in patients with AD-MCI, 2.) To determine the impact of closed-loop 40 Hz tACS on cognitive performance in patients with AD-MCI, and 3.) To assess the relationship between baseline neurodegenerative burden and impact of tACS.

Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits (amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. Gamma waves are important for memory, and in patients with AD, there are fewer gamma waves in the brain. The Tsai lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid and tau in the brain, but also improved memory. A light and sound device was developed for humans that stimulates the brain at 40Hz that can be used safely at home. The goal of this study is to see if using this device can prevent dementia in people who are at risk for developing Alzheimer's disease.

This phase II trial tests whether the addition of radiation to the primary tumor, typically given with stereotactic ablative radiation therapy (SABR), in combination with standard of care immunotherapy improves outcomes in patients with renal cell cancer that is not recommended for surgery and has spread from where it first started (primary site) to other places in the body (metastatic). Radiation therapy uses high energy photons to kill tumor cells and shrink tumors. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses of radiation over a shorter period and cause less damage to normal tissue. Immunotherapy with monoclonal antibodies, such as nivolumab, ipilimumab, avelumab, and pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Axitinib, cabozantinib, and lenvatinib are in a class of medications called antiangiogenic agents. They work by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor. Giving SABR in combination with standard of care immunotherapy may help shrink or stabilize the cancer in patients with renal cell cancer.

This phase III trial studies whether inotuzumab ozogamicin added to post-induction chemotherapy and immunotherapy (chemo-immunotherapy) for patients with High-Risk B-cell Acute Lymphoblastic Leukemia (B-ALL) improves outcomes. Inotuzumab ozogamicin is a monoclonal antibody, which is a type of protein that can bind to certain targets on the surface of cells. Inotuzumab ozogamicin is a monoclonal antibody that is linked to a type of chemotherapy called calicheamicin. Inotuzumab attaches to cancer cells by binding to the CD22 protein on the surface of the cancer cell and delivering calicheamicin inside the cells to kill them. Other drugs used in the chemotherapy regimen, such as cyclophosphamide, cytarabine, dexamethasone, doxorubicin, daunorubicin, methotrexate, leucovorin, mercaptopurine, prednisone, thioguanine, vincristine, and pegaspargase or calaspargase pegol work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Blinatumomab is a specialized type of monoclonal antibody known as a bispecific T-cell engager (BiTE). It works by simultaneously binding to CD19 on cancer cells and CD3 on normal immune cells, bringing them together to destroy leukemia cells. Blinatumomab is a standard part of chemo-immunotherapy treatment for B-ALL. This trial also studies the outcomes of patients with mixed phenotype acute leukemia (MPAL), and B-lymphoblastic lymphoma (B-LLy) when treated with ALL therapy without inotuzumab ozogamicin or blinatumomab. The overall goal of this study is to understand if adding inotuzumab ozogamicin to standard of care chemo-immunotherapy maintains or improves outcomes in High Risk B-cell Acute Lymphoblastic Leukemia (HR B-ALL). The first part of the study includes the first phase of therapy: Induction. This part will collect information on the leukemia, as well as the effects of the initial treatment, to classify patients into post-induction treatment groups. On the second part of this study, patients with HR B-ALL will receive the remainder of the chemotherapy cycles (consolidation, blinatumomab block 1, interim maintenance 1, blinatumomab block 2, delayed intensification, interim maintenance 2, maintenance), with some patients randomized to receive inotuzumab. The patients that receive inotuzumab will not receive part of consolidation or part of delayed intensification. Other aims of this study include evaluating 1) side effects of treatment using patient-reported outcomes and health-related quality of life, 2) the best ways to help patients adhere to oral chemotherapy regimens, 3) the relationship between levels of inotuzumab ozogamicin in the blood and side effects, 4) the impact of chemo-immunotherapy on the immune system and risk of infection, and 5) the impact of social determinants of health on outcomes. Finally, this study will be the first to track the outcomes of subjects with disseminated B-cell Lymphoblastic Leukemia (B-LLy) or Mixed Phenotype Acute Leukemia (MPAL) when treated with B-ALL chemotherapy.

This study will test the hypotheses that adolescent with repetitive negative thinking who at at-risk for serious mental illness will show greater default mode network (DMN) connectivity than healthy controls, at-risk adolescents will show greater changes in DMN connectivity than healthy controls, and that a longer session of mindfulness based neurofeedback will lead to greater reduction in DMN connectivity. To do so, 50 adolescents with elevated repetitive negative thinking and 50 matched healthy control participants will be enrolled into a double-blind randomized clinical trial of a session of mindfulness training with either active mindfulness-basde neurofeedback or sham mindfulness-based neurofeedback.
