This phase II trial tests the safety and best dose of revumenib when given together with chemotherapy, and how well the treatment regimen works for infants and young children with leukemia that has come back (relapsed) or does not respond to treatment (refractory) and is associated with a KMT2A (MLL) gene rearrangement (KMT2A-R). Revumenib is an oral medicine that directly targets the changes that occur in a cell with a KMT2A rearrangement and has been shown to specifically kill these leukemia cells in test tubes and animals. Drugs used in chemotherapy, such as vincristine, prednisone, asparaginase, fludarabine and cytarabine 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. This trial is being done to find out if the combination of revumenib and chemotherapy may help to treat the cancer cells better than either treatment alone.

This research study is designed to compare a new gene therapy, known as OTL-203 (study drug), with a standard treatment called “allogeneic hematopoietic stem cell transplant” (allo-HSCT), to find out which is better for the treatment of MPS-IH.

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 incisions and uses a small camera to help with removing the cancer. This trial is being done evaluate the two different surgery methods for patients with osteosarcoma that has spread to the lung to find out which is better.

The study consists of a non- randomized Phase 1 portion for recurrent or refractory solid tumors followed by potential non- randomized tumor specific cohort(s) and a randomized, Phase 2 portion for recurrent or refractory EWS.

This study is being done to see how safe an investigational drug is and how well it will work to help people with obesity, or overweight with weight-related conditions like hypertension, dyslipidemia, obstructive sleep apnea, non-alcoholic fatty liver disease, or diabetes. If you qualify to be in the study, you will be given frequent lifestyle and behavioral counseling for the first 12 weeks of the study. The counseling will consist of advice on physical activities and dietary advice on healthy eating. During the treatment period, you will receive either tirzepatide or placebo. Placebo is a solution that looks like the study drug but has no medicine. The chance that you will get the study drug is 2 in 3. This phase will last about 72 weeks.

Skytrofa is approved in the U.S. for sale and use in children with growth hormone deficiency (GHD). This study is being done to find out how safe and useful Skytrofa is for long-term treatment. A child’s care will follow the normal treatment practices at the clinic. There is no new treatment or medicine involved and no additional visits will be performed.

Topiramate is a commonly prescribed medication at weight management clinics. While doctors know that some people respond better to topiramate in terms of weight loss and changes in eating behaviors, the reasons WHY some respond better than others are not known. Knowing more about the relationships between topiramate doses, concentrations of topiramate in the blood stream, and an individual’s response to this medicine will help doctors determine those who may be more likely to benefit. Doctors also want to know if someone’s genes (their DNA) may help explain why some people respond better to topiramate than others. We expect that you will be in this research study for about 14 weeks (3.5 months).

In this study we want to find out more about weight loss and how diet and medications can affect weight loss. This study will last for up to 58 weeks. There are two phases to the study: - A weight loss phase with prescribed meals that lasts 6 weeks. - A study medication/placebo phase that lasts up 52 weeks. You will not know if you are receiving the medication or the placebo.

We are conducting a research study for children ages 6-17 with patchy Alopecia Areata (AA). The purpose of this research study is to learn more about the safety, tolerability and efficacy of an investigational drug called Baricitinib. This study will compare the investigational drug to a placebo (inactive substance) to see how well the investigational drug works.

The purpose of this research study is to compare the transfusion of cold-stored (refrigerated) platelets to standard room temperature stored platelets. The goal of the trial is to determine whether platelets stored cold are similar or better at stopping bleeding compared to platelets stored at room temperature and, if so, to determine the maximum duration of cold storage that maintains a similar effect on bleeding

The objective of this study is to create an international registry with long-term follow-up to characterize and evaluate the safety of abatacept in juvenile idiopathic arthritis (JIA). The primary objective of the JIA registry is to describe the long-term safety of abatacept treatment for JIA by quantifying the incidence rates of serious infections, autoimmune disorders, and malignancies.

The purpose of this study is to investigate how effective and safe ZYN002, a transdermal gel, is in participants with FXS. The drug product ZYN002 is a pharmaceutically manufactured CBD. It is being developed as a clear gel that can be applied to the skin (called transdermal delivery), to provide consistent, controlled levels of CBD in the blood when it is given twice a day. Participants will be assigned by chance to get one of the following study treatments: Active study drug – ZYN002 or placebo. Assigning study drug by chance is called “randomization,” and it is an important part of testing an experimental study drug. Participants will be randomly assigned to study treatment according to a computer program and will have 1 in 2 chance of receiving the active study drug.

PR001A is designed to deliver a normal GBA1 gene copy into the body to increase the activity of GCase, which is low in Type 2 Gaucher Disease (GD2) patients. The new GBA1 gene will remain a child’s body cells for many years and possibly for the rest of their life. A participant will need one surgery during which the study drug will be given and will stay in the hospital for at least 48 hours following the surgery.

To assess the safety of Afrezza in a pediatric population when compared to the usual standard of care insulin.

The aim of this study is to investigate whether voclosporin, added to standard treatment, is able to reduce activity of lupus nephritis over a study treatment period of 24 weeks, and to determine its safety as well as the best dose for treatment of lupus nephritis in children or adolescents.

The purpose of this research study is to determine the best dose of FP-045 for Fanconi anemia pediatric and adolescent participants. The study will look at whether the participants have any side effects and if there are any possible changes in something called “biomarkers,” which are blood proteins that will be checked to see if they change when taking FP-045 and that may indicate if FP-045 can delay or prevent disease symptoms. Every participant will receive FP-045.

This phase III trial investigates the best dose of vinblastine in combination with selumetinib and the benefit of adding vinblastine to selumetinib compared to selumetinib alone in treating children and young adults with low-grade glioma (a common type of brain cancer) that has come back after prior treatment (recurrent) or does not respond to therapy (progressive). Selumetinib is a drug that works by blocking a protein that lets tumor cells grow without stopping. Vinblastine blocks cell growth by stopping cell division and may kill cancer cells. Giving selumetinib in combination with vinblastine may work better than selumetinib alone in treating recurrent or progressive low-grade glioma.

Currently, there are no approved treatment options for pediatric subjects with proteinuric kidney conditions. The study will look at the safety, efficacy, and pharmacokinetic (PK) trial in children ≥1 to <18 years treated for up to 108 weeks with the drug sparsentan.

TrialNet is an international research group dedicated to the study, prevention, and early treatment of Type 1 diabetes. Type 1 diabetes is now understood as a disease that develops over time in stages. Stage 1 starts with the appearance of having two or more autoantibodies. This is followed by Stage 2, which is the development of abnormal blood glucose levels. Stage 3 is the clinical diagnosis of Type 1 diabetes. This study will help us learn more about how Type 1 diabetes occurs through the screening of diabetes-related autoantibodies and monitoring individuals who have tested positive for these autoantibodies.
