Filter by:This is a Phase I trial with new experimental drugs such as simvastatin in combination with topotecan and cyclophosphamide in the hopes of finding a drug that may work against tumors that have come back or that have not responded to standard therapy. This study will define toxicity of high dose simvastatin in combination with topotecan and cyclophosphamide and evaluate for cholesterol levels and IL6/STAT3 pathway changes as biomarkers of patient response.
This study will evaluate a uniform chemotherapy protocol for nonmetastatic extraocular retinoblastoma
The goal of this study is to determine if human RB1-deficient induced pluripotent stem cells (iPSCs) can produce retina, and, furthermore, can give rise to retinoblastoma in culture. This unique opportunity to study the initiation of retinoblastoma in the developing retina will shed light on the cell of origin for retinoblastoma and allow the investigators to study the earliest molecular and cellular events in retinoblastoma tumorigenesis. OBJECTIVES: - To establish the feasibility of producing induced pluripotent stem cells (iPSCs) from retinoblastoma patients with germline RB1 mutations (RB1-deficient iPSCs). - To validate human RB1-deficient iPSCs by confirming karyotype, pluripotency and RB1 mutation. - To differentiate the RB1-deficient iPSCs into retina as a model of the initiation of retinoblastoma in the developing retina.
This pilot clinical trial studies whether unilateral group D retinoblastoma, or retinoblastoma affecting one eye that has spread to the inner jelly like part of the eye, can be treated with a new technique for delivering chemotherapy directly into the blood vessel that supplies the affected eye. This new technique is called intra-arterial injection. Giving melphalan via intra-arterial injection may make it less likely that children will need surgery to remove the eye and may reduce the amount of treatment side effects.
MRI is useful for diagnosing pinealoblastoma in retinoblastoma patients
The purpose of this research study is to determine whether taking either of two low dose drugs that would prevent new blood vessels from growing after stem cell transplant is feasible, and what the side effects of taking each of these drugs after autologous transplant might be. The reason the investigators are looking at these drugs is because one of the things that allows tumors to grow quickly is their ability to stimulate the growth of new blood vessels. By suppressing the growth of new blood vessels after stem cell transplant, the investigators hope to prevent the tumors from coming back or continuing to grow.
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).
This is a standard of care treatment guideline for high risk or relapsed solid tumors or CNS tumors consisting of a busulfan, melphalan, thiotepa conditioning (for solid tumors) or carboplatin and thiotepa conditioning (for CNS tumors) followed by an autologous peripheral blood stem cell transplant. For solid tumors, if appropriate, disease specific radiation therapy at day +60. For CNS tumors, the conditioning regimen and autologous peripheral blood stem cell transplant will be given for 3 cycles.
The best treatment for recurrent cancers or those that do not respond to therapies is not known. Typically, patients with these cancers receive a combination of cancer drugs (chemotherapy), surgery, or radiation therapy. These treatments can prolong their life but may not offer a long-term cure. This study proposes using a drug called Sirolimus in combination with common chemotherapy drugs to treat patients with recurrent and refractory solid tumors. Sirolimus has been found to inhibit cell growth and to have anti-tumor activity in pediatric solid tumors in previous studies and, therefore, has the potential to increase the effectiveness of the chemotherapy drugs when given together. This study wil investigate the highest dose of Sirolimus that can be given orally with other oral chemotherapy drugs. Cohorts of 2 subjects will be started at the minimum dose. The dose will be increased in the next 2 subjects as long as there were no major reactions in the previous groups. This study will also seek to learn more about the side effects of sirolimus when used in this combination and what effects the drug has on the white cells and the immune system. Successful use of this drug will impact the cancer population greatly by providing an increased chance of survival to those with resistant or recurrent cancers.
RATIONALE: Seneca Valley virus-001 may be able to kill certain kinds of tumor cells without damaging normal cells. Adding low dose cyclophosphamide (in part B of study) may help to kill even more tumor cells. PURPOSE: This phase I trial is studying the side effects and best dose of Seneca Valley virus-001 in treating young patients with relapsed or refractory neuroblastoma, rhabdomyosarcoma, or rare tumors with neuroendocrine features.
