Methylmalonic acidemia (MMA), one of the most common inborn errors of organic acid metabolism, is heterogeneous in etiology and clinical manifestations. Affected patients with cblA, cblB and mut classes of MMA are medically fragile and can suffer from complications such as metabolic stroke or infarction of the basal ganglia, pancreatitis, end stage renal failure, growth impairment, osteoporosis, and developmental delay. The frequency of these complications and their precipitants remain undefined. Furthermore, current treatment protocol outcomes have continued to demonstrate substantial morbidity and mortality in the patient population. Increasingly, solid organ transplantation (liver, and/or kidney) has been used to treat patients. Disordered transport and intracellular metabolism of vitamin B12 produces a distinct group of disorders that feature methylmalonic acidemia as well as (hyper)homocysteinemia. These conditions are named after the corresponding cellular complementation class (cblC, cblD, cblF, cblJ and cblX) and are also heterogenous, clinically and biochemically. The genetic disorders underlying cblE and cblG feature an isolated impairment of the activity of methionine synthase, a critical enzyme involved in the conversion of homocysteine to methionine and these disorders feature (hyper)homocysteinemia. Lastly, a group of patients can have increased methylmalonic acid and/or homocysteine in the blood or urine caused by variant(s)in recently identified (ACSF3) and unknown genes. In this protocol, we will clinically evaluate patients with methylmalonic acidemia and cobalamin metabolic defects. Routine inpatient admissions will last up to 4-5 days and involve urine collection, blood drawing, ophthalmological examination, radiological procedures, MRI/MRS, skin biopsies in some, and developmental testing. In a subset of patients who have or will receive renal, hepato- or hepato-renal transplants or have an unusual variant or clinical course and have MMA, a lumbar puncture to examine CSF metabolites will be performed. In this small group of patients, CSF metabolite monitoring may be used to adjust therapy. The study objectives will be to further delineate the spectrum of phenotypes and characterize the natural history of these enzymopathies, query for genotype/enzymatic/phenotype correlations, search for new genetic causes of methylmalonic acidemia and/or homocysteinemia, identify new disease biomarkers and define clinical outcome parameters for future clinical trials. The population will consist of participants previously evaluated at NIH, physician referrals, and families directed to the study from clinicaltrials.gov as well as the Organic Acidemia Association, Homocystinuria Network America and other national and international support groups. Most participants will be evaluated only at the NIH Clinical Center. However, if the NIH team decides that a patient under the age of 2 years is a candidate subject for this research protocol, that patient may enroll at the Children s National Medical Center (CNMC) site, pending approval by Dr Chapman, the Principal Investigator of the CNMC location Individuals may also enroll in the tissue collection only part of the study at the UPMC Children s Hospital of Pittsburgh or share medical history and clinical data via telemedicine visits remotely. Outcome measures will largely be descriptive and encompass correlations between clinical, biochemical and molecular parameters. ...

This is an open-label phase 1 safety and feasibility study that will employ multi-tumor antigen specific cytotoxic T lymphocytes (TSA-T) directed against proteogenomically determined personalized tumor-specific antigens (TSA) derived from a patient's primary brain tumor tissues. Young patients with embryonal central nervous system (CNS) malignancies typically are unable to receive irradiation due to significant adverse effects and are treated with intensive chemotherapy followed by autologous stem cell rescue; however, despite intensive therapy, many of these patients relapse. In this study, individualized TSA-T cells will be generated against proteogenomically determined tumor-specific antigens after standard of care treatment in children less than 5 years of age with embryonal brain tumors. Correlative biological studies will measure clinical anti-tumor, immunological and biomarker effects.

This phase II trial tests effects of nivolumab in combination with chemotherapy drugs prior to radiation therapy patients with nasopharyngeal carcinoma (NPC). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as gemcitabine and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Researchers want to find out what effects, good and/or bad, adding nivolumab to chemotherapy has on patients with newly diagnosed NPC. In addition, they want to find out if children with NPC may be treated with less radiation therapy and whether this decreases the side effects of therapy.

It is generally recognized that pain assessment and management especially in newborns, children and other nonverbal populations is an unmet need. According to the American Medical Association, "the pediatric population is at risk of inadequate pain management, with age-related factors affecting pain management in children. Children are often given minimal or no analgesia for procedures that would routinely be treated aggressively in adults. Although much is now known about pain management in children, it has not been widely or effectively translated into routine clinical practice". These two factors combine to emphasize the necessity for an objective tool to quantify pain and monitor the effectiveness of analgesia, especially during treatments. Further, it is reported that many patients require a combination of treatments, and it is often necessary to test a variety of treatments before the personal match for treatment is found. The method in place to change the care on a subjective basis is difficult, time consuming, and not easily individualized. This pilot study is part of an ongoing effort to develop a method to objectively assess response to specific analgesic interventions. It specifically aims to discern the impact of analgesic interventions on sensory nerve fiber sensitivity in a diverse patient population.

Human milk has several well-established benefits but does not adequately meet the increased nutritional demands of the growing preterm infant, necessitating additional nutrient supplementation in a process known as fortification. In U.S. neonatal intensive care units (NICUs), human milk is primarily supplemented using standardized fortification, in which a multicomponent fortifier is added to human milk to achieve assumed nutrient content based on standard milk reference values. However, this method does not account for the significant variability in human milk composition or in preterm infant metabolism, and up to half of all very premature infants experience poor growth and malnutrition using current nutritional practices. Poor postnatal growth has adverse implications for the developing preterm brain and long-term neurodevelopment. Recent advances allow for individualized methods of human milk fortification, including adjustable and targeted fortification. Adjustable fortification uses laboratory markers of protein metabolism (BUN level) to estimate an infant's protein requirements. In targeted fortification, a milk sample is analyzed to determine its specific macronutrient and energy content, with additional macronutrient supplementation provided as needed to achieve goal values. Emerging data suggest that both methods are safe and effective for improving growth, however information on their comparable efficacy and neurodevelopmental implications are lacking, particularly using advanced quantitative brain MRI (qMRI) techniques. Through this prospective, randomized-controlled trial, the investigators will compare the impact of individualized human milk fortification on somatic growth and neurodevelopment in preterm infants. Infants will be randomized to receive one of three nutritional interventions: standardized (control group), adjustable, or targeted human milk fortification. Infants will undergo their assigned nutritional intervention until term-equivalent age or discharge home, whichever is achieved first. Brain qMRI will be performed at term-corrected age, and neurodevelopmental follow-up will be performed through 5 years of age.

This phase II trial determines if the combination of ONC201 with different drugs, panobinostat or paxalisib, is effective for treating participants with diffuse midline gliomas (DMGs). Despite years of research, little to no progress has been made to improve outcomes for participants with DMGs, and there are few treatment options. ONC201, panobinostat, and paxalisib are all enzyme inhibitors that may stop the growth of tumor cells by clocking some of the enzymes needed for cell growth. This phase II trial assesses different combinations of these drugs for the treatment of DMGs.

This phase III trial compares the effects of nivolumab with chemo-immunotherapy versus chemo-immunotherapy alone in treating patients with newly diagnosed primary mediastinal B-cell lymphoma (PMBCL). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of cancer cells to grow and spread. Treatment for PMBCL involves chemotherapy combined with an immunotherapy called rituximab. Chemotherapy drugs 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. Rituximab is a monoclonal antibody. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving nivolumab with chemo-immunotherapy may help treat patients with PMBCL.

Few studies are specifically designed to address health concerns that are already relevant during pregnancy. The consequence is a lack of evidence on best clinical practice. This includes mothers and their babies when pregnancy is complicated by an abnormally slow heart rate due to maternal antibody-mediated heart disease in the unborn baby (fetus). Since the late seventies, it has been possible to detect and monitor fetal disease by ultrasound images and to treat selected conditions with pharmaceuticals administered via the mother. To this day, physicians need to make decisions about the management of such pregnancies without evidence from prospective clinical trials on drug efficacy and safety. The SLOW HEART REGISTRY is a multi-centered prospective observational study that will address the knowledge gap to guide future management of high-degree immune-mediated heart block to the best of care. The study seeks to establish an international database of the management and outcome of affected fetuses, to be used to publish information on the results of currently available prenatal care and to evaluate the need for additional research.
