Philadelphia, PA Paid Clinical Trials

Cellular and humoral immune responses before and after seasonal influenza vaccination will be assessed. Each year, up to 100 participants will be enrolled. To study age-specific differences in immune responses, participants with various years of birth will be enrolled. The investigators hypothesize that humans with different birth years will mount antibody and cellular responses of different specificities following seasonal influenza vaccination. Read Less

Tagraxofusp is a protein-drug conjugate consisting of a diphtheria toxin redirected to target CD123 has been approved for treatment in pediatric and adult patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN). This trial aims to examine the safety of this novel agent in pediatric patients with relapsed/refractory hematologic malignancies. The mechanism by which tagraxofusp kills cells is distinct from that of conventional chemotherapy. Tagraxofusp directly targets CD123 that is present on tumor cells, but is expressed at lower or levels or absent on normal hematopoietic stem cells. Tagraxofusp also utilizes a payload that is not cell cycle dependent, making it effective against both highly proliferative tumor cells and also quiescent tumor cells. The rationale for clinical development of tagraxofusp for pediatric patients with hematologic malignancies is based on the ubiquitous and high expression of CD123 on many of these diseases, as well as the highly potent preclinical activity and robust clinical responsiveness in adults observed to date. This trial includes two parts: a monotherapy phase and a combination chemotherapy phase. This design will provide further monotherapy safety data and confirm the FDA approved pediatric dose, as well as provide safety data when combined with chemotherapy. The goal of this study is to improve survival rates in children and young adults with relapsed hematological malignancies, determine the recommended phase 2 dose (RP2D) of tagraxofusp given alone and in combination with chemotherapy, as well as to describe the toxicities, pharmacokinetics, and pharmacodynamic properties of tagraxofusp in pediatric patients. About 54 children and young adults will participate in this study. Patients with Down syndrome will be included in part 1 of the study. Read Less

The goal of this observational study is to learn about brain development in Juvenile-onset Huntington's Disease (JoHD). The main questions it aims to answer are: * Is brain development different in JoHD than Adult-onset Huntington's Disease (AoHD)? * Can reliable biomarkers for JoHD be found in brain structure and function? Participants will be asked to complete cognitive tests, behavioral assessments, physical and neurologic evaluation, and MRI. Data collected will be compared to populations who are at-risk for HD and who have been diagnosed with HD as adults. Read Less

This is a pilot mechanistic study of the diagnostic utility of sodium-glucose cotransporter-1/2 inhibition (SGLT1/2) on myocardial glucose suppression on FDG PET/CT. The investigators will test whether the addition of a SGLT1/2 inhibitor (SGLT1/2i) plus the standard dietary modification (ketogenic diet) will provide enhanced myocardial glucose suppression. The primary objective is to assess rates of complete myocardial glucose suppression (MGS) with 7 days of sotagliflozin 400 mg QD among healthy volunteers on a background of 1 day (N=20) or 3 days (N=20) of the KD. The secondary goal is to investigate the relationship between sotagliflozin, targeted metabolite levels, and myocardial glucose utilization on FDG-PET. Participants will be asked to: * undergo a screening visit that includes blood tests, vitals, and questions regarding health history/medications * take the provided sotagliflozin as instructed for 7 days leading up to the scan * follow a ketogenic diet as instructed for 1 or 3 days leading up to the scan * undergo an FDG PET/CT scan, which includes vitals and blood draws Read Less

Children with blunt abdominal trauma often get a CT as the first line imaging to evaluate for intra-abdominal organ injury. CT scans have some downsides with regard to radiation exposure, costs, and need for transport. Contrast enhanced ultrasonography has recently shown some promise as a way to detect intra-abdominal organ injury and may be able to replace the need for conventional CT scanning, without the need for ionizing radiation and the ability to be performed at the bedside.

The advent of anti-retroviral therapy (ART) for people living with HIV/AIDS (PLWHA) substantially improved life expectancy but has also led to the critical need to address modifiable risk factors associated with cancer and cardiovascular disease, such as tobacco smoking. HIV-infected smokers lose more life-years due to tobacco use than they do to their HIV infection. There have been relatively few studies of tobacco use treatments for PLWHA and systematic reviews show that there are insufficient data to conclude that tobacco dependence interventions that are efficacious in the general population are efficacious for PLWHA. Further, many studies in this area have lacked randomization and a control group, infrequently used an intent-to-treat (ITT) approach and biological verification of tobacco abstinence, and lacked post-treatment follow-up.10 What investigators do know thus far is that behavioral interventions and the nicotine patch yield moderate effects on cessation; and 2 recent placebo-controlled trials - one in France and one by this lab - found that varenicline is safe and effective for treating tobacco use among PLWHA, but yield quit rates that are substantially lower than those reported in the general population. Thus, there is a critical need to rigorously test novel ways to optimize tobacco cessation treatment for smokers with HIV. Read Less

A prospective study to determine the metabolic effects of the contraceptive vaginal ring among overweight and obese women with polycystic ovary syndrome (PCOS). We will recruit a total of 40 participants and study use of the vaginal ring over a 4-month period. Read Less

Obesity is one possible contributor to severity of multiple sclerosis and progression of the disease. We already know that obesity is a risk determinant for acquiring MS, yet the impact of obesity on pediatric MS disease expression and course is unknown. This study will evaluate the relationship between obesity, obesity-derived inflammatory mediators, and imaging metrics of MS severity in children. Understanding how childhood obesity contributes to MS severity/progression may yield fundamental insights into disease pathobiology - which may thereby lead to effective strategies for halting its progression in its earliest stages.

The overall aim of this study is to see whether long-term electrical stimulation with a home-stimulation device works well and is safe for the treatment of open-angle glaucoma. Open-Angle Glaucoma is a disease where the nerves in the back of your eye die off faster than expected regardless of your eye pressure. Read Less

The purpose of this study is to find out more about STXBP1 and SYNGAP1 related disorders. The information gathered by this study will be used to prepare for clinical treatment trials. The primary objective of the study is to better define and outline the clinical spectrum of STXBP1 and SYNGAP1 through detailed developmental, seizure, and quality of life assessments as an extension of routine clinical care.
