The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EOnonAD) participants, and (3) cognitively normal (CN) control participants.

This study is researching an experimental drug called linvoseltamab when combined with another drug called dupilumab. The study is focused on patients who have IgE-mediated food allergy. If the patient has an allergy, the immune system overreacts to an allergen (eg, certain foods such as peanuts, milk, shellfish) by producing antibodies called IgE. IgE antibodies are released by cells such as plasma cells. These antibodies and allergens bind to other cells that release chemicals, causing an allergic reaction. The aim of the study is to see how safe and tolerable linvoseltamab is when combined with dupilumab. The study is looking at several other research questions, including: - What side effects may happen from taking the study drugs - Whether linvoseltamab when combined with dupilumab has an effect on other types of antibodies in the blood at different times - How much study drug(s) is in the blood at different times

PT217 is a bispecific antibody (bsAb) against human DLL3 (huDLL3) and human CD47 (huCD47). This is a first-in-human, Phase 1/2, open-label, dose-escalation and expansion study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of PT217 in subjects with neuroendocrine carcinomas. Patients with the following tumor types will be eligible for screening: small cell lung cancer (SCLC), large cell neuroendocrine carcinoma of the lung (LCNEC), and extrapulmonary neuroendocrine carcinoma (EP-NEC), including but not limited to neuroendocrine prostate cancer (NEPC) and gastroentero-pancreatic neuroendocrine carcinoma (GEP-NEC). Patients must have progressed after standard therapy (platinum-based chemotherapy) or standard therapy has proven to be ineffective, intolerable or is considered inappropriate.

Despite recent advances in the treatment of solid tumors in general, advanced (metastatic) disease remains mostly incurable and there is an urgent need to develop new therapeutic options for these patients, particularly investigational drugs with novel mechanisms of action. The investigation of new combination regimens of non-crossresistant agents with acceptable-and not completely overlapping-toxicities has been a major way to improve response rate and outcome of patients with advanced solid tumors.

Persistent developmental stuttering affects more than three million people in the United States, and it can have profound adverse effects on quality of life. Despite its prevalence and negative impact, stuttering has resisted explanation and effective treatment, due in large part to a poor understanding of the neural processing impairments underlying the disorder. The overall goal of this study is to improve understanding of the brain mechanisms involved in speech motor planning and how these are disrupted in neurogenic speech disorders, like stuttering. The investigators will do this through an integrated combination of experiments that involve speech production, functional MRI, and non-invasive brain stimulation. The study is designed to test hypotheses regarding the brain processes involved in learning and initiating new speech sound sequences and how those processes compare in persons with persistent developmental stuttering and those with typical speech development. These processes will be studied in both adults and children. Additionally, these processes will be investigated in patients with neurodegenerative speech disorders (primary progressive aphasia) to further inform the investigators understanding of the neural mechanisms that support speech motor sequence learning. Together these experiments will result in an improved account of the brain mechanisms underlying speech production in fluent speakers and individuals who stutter, thereby paving the way for the development of new therapies and technologies for addressing this disorder.

The reason for this study is to see if the study drug, selpercatinib, compared to placebo is effective and safe in delaying cancer return in participants with early-stage non-small cell lung cancer (NSCLC), who have already had surgery or radiation. Participants who are assigned to placebo and stop the study drug because their disease comes back or gets worse have the option to potentially crossover to selpercatinib. Participation could last up to three years.
