NCT00264810
The RNS® System Pivotal study is designed to assess safety and demonstrate that the RNS® System is effective as an adjunctive (add-on) therapy in reducing the frequency of seizures in individuals 18 years of age or older with partial onset seizures from no more than two foci (two areas of the brain) that are refractory (drug-resistant or hard-to-treat) to two or more antiepileptic medications. Patients continue to receive their epilepsy medications while participating in the study.
NCT00002812
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining more than one drug and giving the drugs in different combinations may kill more cancer cells. PURPOSE: Randomized phase III trial to compare the effectiveness of standard combination chemotherapy treatment with more intensive combination chemotherapy in treating children with acute lymphocytic leukemia.
NCT00003203
RATIONALE: Drugs used in chemotherapy, such as carboplatin and vincristine, work in different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining carboplatin and vincristine with radiation therapy followed by adjuvant chemotherapy may kill more tumor cells. PURPOSE: Randomized phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed adjuvant chemotherapy in treating young patients who have newly diagnosed high-risk CNS embryonal tumors.
NCT00331032
The purpose of this study is to test the safety and tolerability of a medication applied vaginally twice daily in females versus placebo (inactive substance). Study participants will include 60 women, ages 18-24, non-pregnant, previously sexually active, Human Immunodeficiency Virus (HIV) negative and sexually transmitted infection (STI) free, in San Francisco or Kisuma, Kenya. Each study participant will be followed for 14 days of product use and an additional 7 days for safety assessments. Study procedures will include a physical exam with a pap smear, urine testing, blood sample testing, and a colposcopy (exam of the vagina and cervix using a lighted magnifying instrument). Information learned from this study may help to develop a safe and effective medication that could prevent herpes simplex virus and HIV. Participants may be involved in study related procedures for up to 55 days.
NCT00862082
The current understanding of PR104 justifies the evaluation of PR104 with sorafenib in patients with hepatocellular carcinoma. These include: * Hypoxia. Hepatocellular Carcinoma (HCC) is likely to demonstrate a level of hypoxia sufficient to activate PR104 to its active metabolites PR104H and PR104M. In addition, in preclinical models, sorafenib has been demonstrated to increase the degree of hypoxia in tumors following treatment. * Non-overlapping toxicity. PR104 and sorafenib do not share major toxicities. It is anticipated that both drugs can be administered at their full single agent dose when used in combination. * Aldo-keto reductase 1C3 (AKR1C3). HCC has been shown to express high levels of AKR1C3 which should lead to selective activation of PR104 within both hypoxic and oxic HCC cells. * Preclinical data. The use of sorafenib and PR104 alone and in combination in a hepatocellular carcinoma model demonstrates activity of PR104 as a single agent and increased activity when PR104 and sorafenib are used in combination. The current study will provide an estimate of the activity of PR104 in subjects with HCC. This information will prove valuable in defining the future clinical development of PR104, and in determining if PR104 has sufficient activity in HCC to warrant a larger phase III registration study in this indication. Primary objectives * Phase I: Determine the maximum tolerated dose (MTD) of PR104 when used in combination with standard dose sorafenib * Phase II: Estimate the response rate (RR) of PR104/sorafenib \[Note: Phase II was never initiated\] Secondary objectives * Evaluate survival * Evaluate Progression Free Survival (PFS) * Evaluate time to progression (TTP) * Evaluate safety * Evaluate the pharmacokinetics (PK) of sorafenib, PR104 and PR104 metabolites * Collect diagnostic biopsy samples for the determination of aldo-keto reductase 1C3 * Collect plasma samples for assessment of potential biomarkers of tumor hypoxia
NCT00002816
RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. PURPOSE: Phase III trial to compare the effectiveness of combination chemotherapy in treating children who have relapsed acute lymphoblastic leukemia.
NCT01587183
This study will test strategies to help people with prehypertension adopt a running program to reduce their blood pressure in the long term. This study will be a 12 week intervention of about 40 participants randomized to running educational material, group based running instruction, or group based running instruction focused on form and all given the option to use the supplemental mHealth intervention. The purpose of this study is to collect feasibility, acceptability and preliminary efficacy data in preparation for a larger planned NIH-R01 study.
NCT00019422
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Lobradimil may increase the effectiveness of a chemotherapy drug by making tumor cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of carboplatin and lobradimil in treating children with brain tumors that have not responded to previous treatment.
NCT01116700
Dexmedetomidine is an alpha-2 agonist commonly used during neurosurgery due to its unique properties as a sedative and anxiolytic with minimal respiratory depression. Neurosurgical patients frequently come to the operating room on anticonvulsant therapy with a history of seizures. The investigators clinical experience suggests that these patients are resistant to the sedative effects of dexmedetomidine. This effect may represent a pharmacokinetic interaction between the anticonvulsant medications and dexmedetomidine or the higher dexmedetomidine dose requirement could result from abnormal pharmacodynamics due to the underlying seizure disorder. The investigators study aims to investigate the pharmacokinetic and pharmacodynamic differences of dexmedetomidine between patients receiving and not receiving enzyme-inducing anticonvulsant therapy and to identify a potential mechanism for these differences.
NCT00552188
The purpose of this study is to determine the effect of VIA-2291 as compared to placebo on vascular inflammation following 24 weeks of dosing.
NCT00043927
This study will gather and compare data about the effectiveness and safety of two different treatments for extensive Small Cell Lung Cancer (SCLC) in patients who have not received previous chemotherapy. One treatment will use an investigational drug in combination with an FDA approved chemotherapy. The other treatment will use a combination of two FDA approved chemotherapy drugs.
NCT01546324
The purpose of this study is to collect blood samples from pregnant women who achieved pregnancy following in-vitro fertilization (IVF) with Natera's preimplantation aneuploidy screening (with or without single gene gene testing).
