This phase II/III trial tests the safety, side effects, and best dose of the drug cabozantinib in combination with standard chemotherapy, and to compare the effect of adding cabozantinib to standard chemotherapy alone in treating patients with newly diagnosed osteosarcoma. Cabozantinib is in a class of medications called kinase inhibitors which block protein signals affecting new blood vessel formation and the ability to activate growth signaling pathways. This may help slow the growth of tumor cells. The drugs used in standard chemotherapy for this trial are methotrexate, doxorubicin, and cisplatin (MAP). Methotrexate stops cells from making DNA and may kill tumor cells. It is a type of antimetabolite. Doxorubicin is in a class of medications called anthracyclines. It works by slowing or stopping the growth of tumor cells in the body. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of tumor cells. Adding cabozantinib to standard chemotherapy may work better in treating newly diagnosed osteosarcoma.

The TSC Biosample Repository collects and stores samples of blood, DNA, and tissues that scientists can request to use in their research. The samples we collect are all linked to clinical data in the TSC Natural History Database. The TSC Natural History Database captures clinical data to document the impact of the disease on a person's health over his or her lifetime. This data may be collected retrospectively or prospectively.

The primary aim of this project are to evaluate a comprehensive, practice-ready, and deployment-focused strategy for improving the prediction and prevention of suicide attempts among a sample of 4,000 patients presenting to an ED with a psychiatric concern. The first aim is to evaluate the effects of providing information about risk of patient suicidal behavior to ED clinicians. The investigators hypothesize that patients randomly assigned to have their clinician receive their risk score will have a lower rate of suicide attempts during 6-month follow-up and that this effect will be mediated by changes in clinician decision-making.

The main purpose of this study is to learn more about the safety, side effects, and effectiveness of LOXO-435 by itself or when it is combined with other standard medicines that treat cancer. LOXO-435 may be used to treat cancer of the cells that line the urinary system and other solid tumor cancers that have a change in a particular gene (known as the FGFR3 gene). Participation could last up to 30 months (2.5 years) and possibly longer if the disease does not get worse.

The Pompe Registry is a global, multicenter, international, longitudinal, observational, and voluntary program for patients with Pompe disease, designed to track the disease's natural history and outcomes in patients, both treated and not. Data from the Registry are also used to fulfill various global regulatory commitments, to support product development/reimbursement, and for other research and non-research related purposes. The objectives of the Registry are: - To enhance understanding of the variability, progression, identification, and natural history of Pompe disease, with the ultimate goal of better guiding and assessing therapeutic intervention. - To assist the Pompe medical community with the development of recommendations for monitoring patients, and to provide reports on patient outcomes, to optimize patient care. - To characterize the Pompe disease population. - To evaluate the long-term effectiveness of alglucosidase alfa.

Lupus nephritis is a chronic and life-threatening autoimmune cause of kidney disease that predominately impacts young people and can lead to kidney failure. Sodium-glucose co-transporter-2 inhibitors, including dapagliflozin, are known to improve outcomes for people with other causes of chronic kidney disease. This pilot and feasibility randomized clinical trial will test the use of dapagliflozin versus placebo in addition to standard of care treatment for patients with early and active lupus nephritis, a group who has not been included in past trials.

This study is researching an experimental drug called ubamatamab, also referred to as "study drug". The study is focused on patients who have advanced ovarian cancer. The aim of the study is to see how safe, tolerable, and effective the study drug is on its own and in combination with other anti-cancer drugs (bevacizumab, cemiplimab, fianlimab and a standard chemotherapy drug, pegylated liposomal doxorubicin [PLD]), referred to as "combination drugs'. The study is looking at several other research questions, including: - What side effects may happen from taking the study drug and its experimental combinations - How much study drug and fianlimab is in the blood at different times - Whether the body makes antibodies against the study drug (which could make the drug less effective or could lead to side effects) and its combinations
