NCT04344626
Refractory epilepsy, meaning epilepsy that no longer responds to medication, is a common neurosurgical indication in children. In such cases, surgery is the treatment of choice. Complete resection of affected brain tissue is associated with highest probability of seizure freedom. However, epileptogenic brain tissue is visually identical to normal brain tissue, complicating complete resection. Modern investigative methods are of limited use. An important subjective assessment during surgery is that affected brain tissue feels stiffer, however there is presently no way to determine this without committing to resecting the affected area. It is hypothesized that intra-operative use of a tonometer (Diaton) will identify abnormal brain tissue stiffness in affected brain relative to normal brain. This will help identify stiffer brain regions without having to resect them. The objective is to determine if intra-operative use of a tonometer to measure brain tissue stiffness will offer additional precision in identifying epileptogenic lesions. In participants with refractory epilepsy, various locations on the cerebral cortex will be identified using standard pre-operative investigations like magnetic resonance imagin (MRI) and positron emission tomography (PET). These are areas of presumed normal and abnormal brain where the tonometer will be used during surgery to measure brain tissue stiffness. Brain tissue stiffness measurements will then be compared with results of routine pre-operative and intra-operative tests. Such comparisons will help determine if and to what extent intra-operative brain tissue stiffness measurements correlate with other tests and help identify epileptogenic brain tissue. 24 participants have already undergone intra-operative brain tonometry. Results in these participants are encouraging: abnormally high brain tissue stiffness measurements have consistently been identified and significantly associated with abnormal brain tissue. If the tonometer adequately identifies epileptogenic brain tissue through brain tissue stiffness measurements, it is possible that resection of identified tissue could lead to better post-operative outcomes, lowering seizure recurrences and neurological deficits.

NCT00752154
Curcuma longa or turmeric is a tropical plant native to south and southeast tropical Asia. Perhaps the most active component in turmeric is curcumin which may make up 2-5% of the total spice in turmeric. The study drug being tested in this study is curcumin. This study is called a cross-over study because all subjects will receive the study drug for a certain amount of time and then switch to placebo (an inactive substance) for a certain time or vice versa. The subject's participation may last up to 8 months. The subject will be randomized (by chance; like flipping a coin) to receive either the study drug, curcumin, or placebo for 4 months. After 4 months, if the subject was taking curcumin they will stop taking it and begin to take placebo and if the subject was taking placebo they will stop taking it and begin taking curcumin for the remaining 4 months. By completion of the study, all 40 subjects will have taken curcumin and placebo for 4 months each. Curcumin/placebo will be provided in capsule form and the subject will take it by mouth. The dose dose will be increased every week for up to a total of 4 grams per day. Subjects will have blood tests, complete questionnaires, and be seen by the study doctor.
NCT01825694
This study plans to develop an integrated treatment for comorbid post-traumatic stress disorder (PTSD) and substance abuse (SA) in adolescents. The investigators aim to develop a treatment approach that is community-friendly, well-tolerated, and deliverable by substance abuse counselors (SAC) in outpatient settings. The proposed Trauma-Focused Substance Abuse Treatment (TFSAT) aims to reduce PTSD symptoms and substance use and build coping skills. The investigators propose to adapt an evidence-based trauma program, Cognitive-Behavioral Intervention for Trauma in Schools (CBITS), for adolescent substance abusers (ASAbusers); to assess the acceptability and feasibility of the integrated approach; and to pilot test the new program against standard care. The investigators hypothesize that the intervention group, compared to the control group, will reduce substance use and symptoms for traumatic stress.
NCT02793466
This clinical trial is the first clinical trial to study Durvalumab, a checkpoint inhibitor which stimulates the patient's own immune system to act against cancer cells in children and adolescents. This trial will assess the safety and tolerability of Durvalumab in children and adolescents and also study how Durvalumab is processed in their bodies.
NCT02996266
This study will assess the impact of fever prevention on fever burden and short- and long-term neurologic outcomes in brain injured patients. Half of the subjects will undergo fever prevention using a targeted temperature management system and half of the subjects will be treated for fever should it develop.
NCT03471078
Phase 3 randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of avatrombopag in subjects with chemotherapy-induced thrombocytopenia receiving chemotherapy for the treatment of ovarian, lung (small cell and non-small cell) and bladder cancer.
NCT02509052
This phase I/II trial studies the side effects and best dose of leflunomide in treating patients with multiple myeloma that has come back (relapsed) or has not responded to previous treatment (refractory). Leflunomide may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
NCT04171843
This is a Phase 1/2a, nonrandomized, open-label, parallel assignment, single-dose, dose-escalation, and dose-expansion study to evaluate the safety and clinical activity of PBCAR269A, with or without nirogacestat, in adults with r/r MM. Study subjects in Cohort A will receive PBCAR269A and study subjects in Cohort B will receive PBCAR269A and nirogacestat. At each dose level, study subjects in Cohort A and Cohort B will receive the same dose of PBCAR269A. In Cohort B, all study subjects will follow the same dosing regimen of nirogacestat. This study was terminated prior to beginning of Phase II due to lack of sufficient therapeutic effect
NCT04740827

NCT02682927
Study 1 and Study 3 are the prospective, merged analyses of 2 identical double-blind, placebo-controlled studies, ZX008-1501 and ZX008-1502, to assess the efficacy, safety, and pharmacokinetics of ZX008 when used as adjunctive therapy in pediatric and young adult subjects with Dravet syndrome. Study 1501 and Study 1502 were conducted in parallel; Study 1501 was conducted at approximately 30 study sites in North America; Study 1502 was conducted at approximately 30 study sites in Europe, Asia and Australia. Upon completion of the Baseline Period after initial Screening and Baseline charting of seizure frequency, subjects who qualified for the studies were randomized (1:1:1) in a double-blind manner to receive either 1 of 2 doses of ZX008 (0.2 mg/kg/day or 0.8 mg/kg/day; maximum dose: 30 mg/day) or placebo. Randomization was stratified by age group (\< 6 years, ≥6 to 18 years) to achieve balance across treatment arms, with the target of 25% of subjects in each age group. All subjects were titrated to their randomized dose over a 14-day Titration Period. Following titration, subjects continued treatment at their randomly assigned dose over a 12-week Maintenance Period. Subjects exiting the study underwent a 2-week taper, unless they enrolled in a follow-on study. Subjects were followed for post-study safety monitoring.

NCT03803761
This phase I/II trial studies the side effects and how well copanlisib works when given together with fulvestrant in treating patients with estrogen receptor positive (ER+) and human epidermal growth factor receptor 2 negative (HER2-) breast cancer that has spread to other places in the body (advanced) and progressing after prior treatment. HER2 and ER are two types of proteins called receptors that can affect the growth of breast cancer cells. Additionally, investigators hope to learn from this study if tumor genetic information is important for predicting whether this type of breast cancer will respond to fulvestrant and copanlisib. Copanlisib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Hormone therapy using fulvestrant may fight breast cancer by blocking the use of estrogen by the tumor cells. Giving copanlisib and fulvestrant may work better in treating patients with ER+ and HER2- breast cancer compared to fulvestrant alone.
