Filter by: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 is a single-arm, open-label study to assess the safety, pharmacokinetics, pharmacodynamics, and preliminary efficacy of talazoparib in patients with advanced tumors with DNA-repair pathway deficiencies. There will be 2 parts to the study: a dose escalation phase in which the maximum tolerated dose will be defined, and a dose expansion phase.
Patients with relapsed solid tumors such as sarcomas and neuroblastoma have a poor survival, generally < 20%. There is an urgent need for new treatments that are safe and effective. HSV1716, an oncolytic virus, is a mutant herpes simplex virus (HSV) type I, deleted in the RL1 gene which encodes the protein ICP34.5, a specific determinant of virulence. Mutants lacking the RL1 gene are capable of replication in actively dividing cells but not in terminally differentiated cells - a phenotype exploited to selectively kill tumor cells. In previous clinical studies, HSV1716 has been shown to be safe when injected at doses up to 10^5 plaque forming units (pfu) directly into human high-grade glioma and into normal brain adjacent to tumour, following excision of high-grade glioma. In an extension study, HSV1716 has been shown to be safe when injected at a dose of up to 10^6 pfu directly into brain tumours. Replication of HSV1716 in human glioblastoma in situ has been demonstrated. Following a single administration of HSV1716 by direct injection into active recurrent tumor or brain adjacent to tumor, some patients have lived longer than might have been expected. This study seeks to evaluate the safety of a single injection of HSV1716 in the treatment of extracranial solid tumors in adolescents and young adults. HSV1716 has also proved safe when given by direct intra-tumoural injection in patients with squamous carcinoma of the head and neck, and in patients with malignant melanoma. Replication of HSV mutants in human sarcomas and neuroblastoma in cultured cells and human xenograft models has been demonstrated. This study is designed in two parts. PART 1 of the study specifies a single dose of virus. Participants who experience at least stable disease or relapse following a determination of stable disease, may qualify for subsequent doses in PART 2. PART 2 requires signing of a separate consent.

Relapsed and/or refractory neuroblastoma, osteosarcoma, Ewing sarcoma and melanoma are considered difficult to treat and cure. For this study we are testing the use of a new experimental (investigational) antibody called hu14.18K322A. GD2 is expressed on the surface of most of these tumor types. Two schedules of hu14.18K322A antibody will be evaluated in this study, (1) daily for four consecutive days schedule every 28 days and (2) once weekly for 4 weeks schedule every 28 days. Approximately 25-40 participants will be required to define the maximum tolerated dose for each schedule. Participants will continue on treatment for a maximum of 4 to 8 courses or until one or more of the criteria for off-treatment are met.
This laboratory study is evaluating how well dactinomycin and vincristine work in treating young patients with cancer. Studying samples of blood and urine in the laboratory from patients with cancer may help doctors learn how dactinomycin and vincristine affect the body and how patients will respond to treatment.
Patients who are being considered for participation in a NCI Pediatric Oncology Branch research study will be screened for eligibility under this protocol. For every NCI research study, patients must meet defined medical criteria in order to ensure the integrity of the research study and to maximize patient safety. Tests and procedures required for determining eligibility depend on the specific study for which the patient is being considered. Some of the more common tests and procedures are: - History and physical examination - Blood and urine samples for routine laboratory tests and possibly research studies - Quality of life assessment questionnaire - Magnetic resonance imaging (MRI) scan uses a magnetic field and radio waves to produce pictures of body structures, including tumors - Computerized tomography (CT) scan uses radiation to produce multiple detailed pictures of body structures - X-rays uses radiation to provide a single picture of a body part - Nuclear medicine scans uses a chemical tagged with a radioactive substance to detect tumors, measure kidney or heart function, or monitor the flow of cerebrospinal fluid (fluid that bathes the brain and spinal cord) - Electrocardiogram (EKG) uses electrodes placed on the skin to evaluates heart rate and rhythm by measuring electrical impulses from the heart - Echocardiogram uses high-frequency sound waves to evaluate heart structure and function - Lumbar puncture tests for cancer cells and other substances in cerebrospinal fluid. Involves placing a needle into the lower back between the bones of the spine and withdrawing a fluid sample from the fluid-containing space below the spinal cord - Ommaya reservoir surgically implanted catheter inserted into the fluid-filled ventricles of the brain, used to withdraw spinal fluid samples and to give medication - Eye examination vision test and eye examination - Biopsies removal of a small piece of tissue, by needle or by surgery, for examination under the microscope. An area of skin over the biopsy site is numbed with an anesthetic. For a needle biopsy, a needle is inserted into the tumor, tissue or bone marrow to pull out a small sample. A surgical biopsy may be done in the operating room, clinic, or hospital room, depending on the biopsy location. The tissue or tumor is removed by cutting a small piece of it with a sharp knife or scalpel and the area will be closed with sutures or staples.
