Measuring Analgesic Interventions
Recruiting
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 chi... Read More

Physiologic Measure of VIPN
Recruiting
The purpose of this study is the development of a physiologic endpoint using a novel technology that would provide an objective, easy to use and more sensitive assessment of VIPN in children and adolescents. The ability to more easily detect and monitor VIPN, even before it is clinically evident, would facilitate optimizing the dosing of vincristine for maximal disease response while minimizing the risk of lifelong functional deficits affecting quality of life. This approach would also enable th... Read More

Development of a Therapeutic Endpoint in Pediatric Rheumatologic Conditions
Recruiting
The overarching goal of this study is the development of a physiologic endpoint of pain and treatment effect in three distinct rheumatology populations. This would enable objective assessment of pain and treatment in these populations and enable a much more precise approach to treatment. Such an endpoint stands to significantly improve outcomes in these patients by eliminating the need for a trial-and-error approach to treatment. This is a single site observational study that aims to collect ini... Read More

Therapeutic Endpoint in Pediatric IBD Conditions
Recruiting
The purpose of this clinical study is the development of physiologic endpoint of inflammation in pediatric patients diagnosed with inflammatory bowel disease (IBD), specifically subtypes Crohn's disease (CD) and ulcerative colitis (UC). The novel medical device evaluates the patient's sensory response to each of the three sensory nerve fiber types. Data from the device provides an assessment of disease activity and a more precise approach to treatment.

A Study to Compare Blinatumomab Alone to Blinatumomab With Nivolumab in Patients Diagnosed With First Relapse B-Cell Acute Lymphoblastic Leukemia (B-ALL)
Recruiting
This phase II trial studies the effect of nivolumab in combination with blinatumomab compared to blinatumomab alone in treating patients with B-cell acute lymphoblastic leukemia (B-ALL) that has come back (relapsed). Down syndrome patients with relapsed B-ALL are included in this study. Blinatumomab is an antibody, which is a protein that identifies and targets specific molecules in the body. Blinatumomab searches for and attaches itself to the cancer cell. Once attached, an immune response occu... Read More
