Filter by:This study evaluate the effect of dexmedetomidine on intelligence test in pediatric patients with multiple anesthesia exposure. Children who are diagnosed with retinoblastoma and receive first exam under general anesthesia before age of 2 are included. Intelligence test will performed when patients' age are 4.
This protocol includes 2 independent studies. Both studies are multicenter studies, evaluating different therapeutic approaches in two different populations of patients: - Study 1, a randomized phase-II study evaluating the efficacy of Intra-Arterial Chemotherapy (IAC) with melphalan and topotecan versus melphalan alone, both in association with ophthalmologic treatments. - Study 2, a minimally invasive interventional study evaluating the results on visual function following reference treatment with intravenous (IV) chemotherapy in association with ophthalmologic or local ophthalmological treatment without IV chemotherapy.
The primary objective of the study is to evaluate the effect of intravenously infused nitroglycerin on the incidence of the cardio-respiratory side effects during the intra-arterial chemotherapy for retinoblastoma in pediatric patients. The intra-arterial chemotherapy at the ophthalmic artery is an important treatment option for retinoblastoma. However, the cardio-respiratory side effects (sudden onset of bradycardia, hypotension, a severe decrease in the compliance of lung, hypoxia) occasionally occurs during catheter manipulation in the ophthalmic artery. One of the purported mechanisms of cardio-respiratory side effects is vagal activation from the activation of trigeminal ganglion by afferent signals from the ophthalmic artery. Additionally, the chemotherapy agent can cause intra-arterial retinal precipitates. Therefore, it is expected that the dilation of the retinal artery may reduce the cardio-respiratory side effects and intra-arterial retinal precipitates. The hypothesis of this study is that the intravenously infused nitroglycerin will increase the compliance of the ophthalmic and retinal artery and decrease vagal stimulation and cardio-respiratory side effects during catheter manipulation and chemotherapy agent infusion. This is a single-center, double-blind, randomized, placebo-controlled study comparing the effect of intravenously infused nitroglycerin and saline on the incidence of the cardio-respiratory side effect in pediatric retinoblastoma patients undergoing intra-arterial chemotherapy. Prior to the procedure, each patient will be randomized into either the control-first arm, saline, or study-first arm, nitroglycerin.
Prospective observational study in patients undergoing intra-arterial ophthalmic artery chemotherapy for the treatment of retinoblastoma. The main objective of the study is to evaluate the incidence of cardiorespiratory autonomic reflexes in these patients and to investigate the association between autonomic reflexes and perioperative clinical characteristics.
This single site, single-arm, non-randomized, dose escalation phase I toxicity clinical trial will assess primarily the safety and secondarily the efficacy of episcleral topotecan in patients with active residual or recurrent intraocular retinoblastoma in at least one eye following completion of first-line therapy.
As the survival of children with retinoblastoma in high income countries is higher than 95% including the bilateral forms this study hopes to improve the outcome in low income countries in Africa by improving early diagnosis and early implementation of this protocol of therapeutic recommendations for treatment.
This trial studies health outcomes after treatment in patients with retinoblastoma. Gathering health information over time from patients and family members through vision assessments, samples of tissue and saliva, and questionnaires may help doctors learn more about what causes retinoblastoma, identify long-term health outcomes for patients with retinoblastoma, and find out which therapies may be the best for treating retinoblastoma
This is a phase I, open-label, non-randomized study that will enroll pediatric and young adult research participants with relapsed or refractory non-CNS solid tumors to evaluate the safety, feasibility, and efficacy of administering T cell products derived from the research participant's blood that have been genetically modified to express a EGFR-specific receptor (chimeric antigen receptor, or CAR) that will target and kill solid tumors that express EGFR and the selection-suicide marker EGFRt. EGFRt is a protein incorporated into the cell with our EGFR receptor which is used to identify the modified T cells and can be used as a tag that allows for elimination of the modified T cells if needed. On Arm A of the study, research participants will receive EGFR-specific CAR T cells only. On Arm B of the study, research participants will receive CAR T cells directed at EGFR and CD19, a marker on the surface of B lymphocytes, following the hypothesis that CD19+ B cells serving in their normal role as antigen presenting cells to T cells will promote the expansion and persistence of the CAR T cells. The CD19 receptor harbors a different selection-suicide marker, HERtG. The primary objectives of the study will be to determine the feasibility of manufacturing the cell products, the safety of the T cell product infusion, to determine the maximum tolerated dose of the CAR T cells products, to describe the full toxicity profile of each product, and determine the persistence of the modified cell in the subject's body on each arm. Subjects will receive a single dose of T cells comprised of two different subtypes of T cells (CD4 and CD8 T cells) felt to benefit one another once administered to the research participants for improved potential therapeutic effect. The secondary objectives of this protocol are to study the number of modified cells in the patients and the duration they continue to be at detectable levels. The investigators will also quantitate anti-tumor efficacy on each arm. Subjects who experience significant and potentially life-threatening toxicities (other than clinically manageable toxicities related to T cells working, called cytokine release syndrome) will receive infusions of cetuximab (an antibody commercially available that targets EGFRt) or trastuzumab (an antibody commercially available that targets HER2tG) to assess the ability of the EGFRt on the T cells to be an effective suicide mechanism for the elimination of the transferred T cell products.
The purpose of this study is to see if there is a difference between the development of the brain (neurodevelopment) in children who have been treated for retinoblastoma with multiple anesthetic exposures, compared with brain development in children who have never had anesthesia.
Retinoblastoma is the most frequent intraocular tumor in children and represents 6% of all pediatric cancers before the age of 5 years-old. The outcome is now excellent with 95 to 97% of 5-years survival rate. Conservative treatments are being more and more used, and intra arterial chemotherapy is one of the adjuvant treatments proposed to the children. The treatment is efficient in most cases, but a small proportion of children will have an early progression after treatment. MRI is used for the diagnosis of retinoblastoma. We aim to find prognostic factors using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) for early identification of children response to intra arterial chemotherapy.
