Filter by:The purpose of this study is to assess the safety, pharmacokinetic and activity profiles of the ch14.18 antibody produced in cells of hamster origin (ch14.18/CHO).
The purpose of this study is to find out if "humanized 3F8" (Hu3F8) when combined with interleukin-2 (rIL2) is safe for treating neuroblastoma and other cancers. A phase 1 study means the investigators are trying to find out what side effects happen when higher and higher doses of a drug are used. The investigators want to find out what effects, good and/or bad, Hu3F8 combined with rIL2 has on cancer. The amount of Hu3F8 that patients gets will depend on when they start treatment on this study. The amount of rIL2 will be the same for all patients. The investigators also want to find out more about how Hu3F8 works and how effective it is in attacking the disease when combined with rIL2.
Well-regulated glycosylation is essential for the normal development of the nervous system. Altered expression of glycosyltransferases with resulting dysregulated glycosylation of neuroblastic cells might lead to the development of NB. The β1,4-N-acetylgalactosaminyltransferase III (B4GALNT3) exhibits GalNAc transferase activity to form the GalNAcβ1,4GlcNAc (LacdiNAc or LDN) structure. The Drosophila B4GALNTA, homolog of human B4GALNT3, has been suggested to regulate the neuronal development. By immunohistochemical studies, we demonstrated that the expression of B4GALNT3 correlated well with histological grade of differentiation in NB tumor samples. Since well differentiated tumors usually carry a better prognosis, we thus speculate that expression of B4GALNT3 in tumor tissues can a favorable prognostic factor of NB. To explore the role of B4GALNT3 in the prognosis of NB, we propose the following project with two specific aims: Aim Ⅰ: Establishing the significance of B4GALNT3 in the prognosis of NB: We plan to collect 90 NB tumor samples, and evaluate the RNA and protein expression levels by Q-PCR, Western blot, and immunohistochemistry in the tumor samples. The results will be compared with the other clinicopathological and biological factors of NB. Also the expression levels of B4GALNT3 in tumor tissues will be correlated to the patients' outcome to clarify whether B4GALNT3 could be a prognosis marker of NB. Aim II: Clarifying the effects of B4GALNT3 on NB cell behavior in vitro and in vivo. For further strengthening the prognostic role of B4GALNT3 in NB, NB cell phenotype and behavior changes after overexpression or knock-down of B4GALNT3 are evaluated by in vitro assays as well as by a nude mice xenograft model. In summary, if our project can establish the role of B4GALNT3 expression in NB, we may further subclassify the NB patients, and give the NB patients more appropriate therapies to improve patients' outcome. Furthermore, B4GALNT3 could potentially serves as a therapeutic target in the future.
This is a phase I study designed to determine the feasibility of transplantation using a novel transplant approach that employs a two-stage haploidentical cell infusion following myeloablative conditioning. This strategy, which includes selective depletion of naïve T cells, may speed immune reconstitution thereby potentially reducing the limitations of traditional haploidentical hematopoietic stem cell transplantation (HSCT) and increasing its potential therapeutic application. Additionally, the investigators intend to explore overall survival, event-free survival, hematopoietic cell recovery and engraftment as well as infection rates and complications in these patients.
This protocol is designed to test the efficacy of 68Ga-DOTATOC PET/CT in diagnosis, staging, and measurement of response to treatment in patients with somatostatin receptor positive tumors. Goals are to 1) compare this unique PET/CT scan with the current standard of care which is a combination of Octreoscan SPECT (single photon emission tomography) plus a high resolution, contrast enhanced CT; 2) Determine the sensitivity of 68Ga-DOTATOC PET/CT in diagnosis of patients with suspected somatostatin receptor positive tumor; and 3) For those patients who have had recent treatment (e.g., surgery, chemotherapy, targeted therapy such as anti-angiogenics, kinase inhibitors, peptide receptor radiotherapy), this scan will be used to measure response to treatment. These studies will be obtained with the long term goal of submitting a New Drug Application (NDA) for FDA approval of 68Ga-DOTATOC PET/CT in adults and children.
This phase I trial studies the side effects and the best dose of crizotinib when given together with combination chemotherapy in treating younger patients with solid tumors or anaplastic large cell lymphoma that has returned or does not respond to treatment. Crizotinib may stop the growth of tumor or cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cyclophosphamide, topotecan hydrochloride, dexrazoxane hydrochloride, doxorubicin hydrochloride, and vincristine sulfate, 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. Giving crizotinib together with combination chemotherapy may be a better treatment for patients with solid tumors or anaplastic large cell lymphoma.
The goal of the first part of this clinical trial (Phase I portion) is to study the side effects, drug breakdown (pharmacokinetics), and dosing of the drug MLN8237 when added to standard chemotherapy drugs, irinotecan and temozolomide. The goal of the second part of this clinical trial (Phase II portion) is to learn how many children and young adults show improvements in their neuroblastoma when treated with the combination of MLN8237, irinotecan, and temozolomide.
This study will be carried out in children with diagnosis of cancer with tumors known to express N-glycolylated gangliosides. The disease must be resistant to conventional therapy. The acute toxicity and immune response will be evaluated. The expression of N-glycolylated gangliosides in tumors has previously been investigated in the tumor sample bank at this Hospital. The expression of N-glycolyl GM3 was shown in neuroblastoma, Ewing's sarcoma, Wilm's tumor and retinoblastoma. Gliomas and the aforementioned tumor types have a very bad prognosis when conventional treatment is ineffective. New therapeutic strategies have thus been examined, and several immunotherapeutic approaches, including dendritic cell vaccines, peptide vaccines and anti-idiotype vaccines are currently being assessed. Racotumomab is an anti-idiotype antibody capable of inducing anti-N-glycolyl GM3 antibodies in patients with melanoma, breast cancer and lung cancer. Dose escalation studies have shown the safety of racotumomab in the 0.5 to 2 mg dose range. The 1 mg dose level was selected for the ensuing clinical studies. This clinical trial in children involves three dose levels: 0.15 mg, 0.25 mg and 0.4 mg, owing to the difference in body surface between an adult (1.73 sq. m in average) and the candidate population for this study (0.55 to 0.7 sq. m).
The purpose of this study is to compare the pharmacokinetics (blood levels) and safety of chimeric (ch) 14.18 manufactured by two independent drug makers (United Therapeutics [UTC] or the National Cancer Institute [NCI]).
This research studies chromosomes in samples from younger patients with neuroblastoma. Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
