NCT02072226
PRISMS is a double-blind, multicenter, randomized, Phase IIIb study to evaluate the efficacy and safety of intravenous (IV) alteplase in participants with mild acute ischemic strokes that do not appear to be clearly disabling. Participants will be randomized in a 1:1 ratio to receive within 3 hours of last known well time either 1) one dose of IV alteplase and one dose of oral aspirin placebo or 2) one dose of IV alteplase placebo and one dose of oral aspirin 325 milligrams (mg).
NCT00985842
Amputee gait produces periodic occlusion of residual limb blood vessels. During the stance phase of gait, body weight cause the prosthesis to compresses the soft tissue of the residual limb and occlude blood flow. This occlusion can be relieved during swing phase, but may depend on type of prosthesis. The purpose of the proposed research is to: (1) discover the range of tissue oxygenation in the intact and residual lower limbs of dysvascular amputees during gait and (2) to learn which of five different prosthetic limb systems provides greater tissue oxygenation.

NCT00546078
Infection with human papillomavirus (HPV) has been clearly established as the central cause of cervical cancer. This study will further evaluate induction of immune memory and anamnestic responses in women who previously took part in the primary study (580299/001) and follow-up study (580299/007). Subjects were aged 15-25 yrs at the time of entry into the primary study and participation in the follow-up study lasted approximately 6 years. In the primary and follow-up studies, subjects were protected against HPV-16 and HPV-18 endpoints and had sustained antibody responses to both vaccine types over at least 5.5 years of follow-up. All subjects from North American study sites that completed the follow-up study will be invited to take part in the current study. The study will evaluate the safety and immunogenicity of a dose of GSK Biologicals HPV vaccine (580299) in women who had been immunologically primed in the primary study. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
NCT01343485
Planned Parenthood Federation of America's (PPFA) Medical Affairs Division will conduct a prospective, cluster randomized trial to determine which factors influence the acquisition of the second and third human papillomavirus (HPV) vaccine doses among young women ages 19 to 26. This descriptive and interventional study will provide data to assess impact of a computerized tool upon HPV vaccine series completion. The interventional aspect of this study includes determination of patient assistance and provider support programs applicable to each woman's situation as well as the implementation of a computer software system for customized patient reminders.
NCT01907269
The purpose of this study is to conduct a randomized trial of a tailored intervention designed to provide personalized feedback regarding patients' risk of subsequent fractures, customized information regarding osteoporosis care, and messaging to activate patients to become more engaged in improving osteoporosis treatment and doctor-patient communication. This novel content will use "story-telling" delivered via the Internet and digital video discs (DVDs). The content will be uniquely tailored to each person based on barriers to care, age and race/ethnicity. We will conduct a controlled, cluster-randomized trial of this intervention to determine differences in post-intervention rates of osteoporosis care between two randomization arms. We hypothesize that participants randomized to the intervention arm, compared to those randomized to a control arm, will receive more osteoporosis care at 6 months post-intervention, as evidenced by higher rates of: (H1) Prescription osteoporosis therapies, (H2) Non-prescription therapy with calcium and vitamin D, and (H3) Bone mineral density (BMD) testing.
NCT00132301
VA Cooperative Study #553 is designed to prospectively evaluate the efficacy of early adjuvant chemotherapy using docetaxel and prednisone added to the standard of care for patients who are potentially cured by radical prostatectomy but who are at high risk for relapse. The standard of care is surveillance, with the addition of androgen deprivation at the time of biochemical relapse. This study will assess the effect of adding early chemotherapy to the standard of care on progression free survival in Veterans at high risk for progression after prostatectomy.
NCT02600611
This is a multicenter, randomized, double-blind study of the efficacy and safety of iclaprim compared to vancomycin for the treatment of skin and skin structure infections.
NCT00002569
RATIONALE: Drugs used in chemotherapy use 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 chemotherapy with radiation therapy may kill more tumor cells. PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without chemotherapy in treating patients who have anaplastic oligodendroglioma.
NCT01807585
The VeClose pivotal study was a controlled, randomized, prospective, multicenter, pivotal study in which patients with venous reflux in the great saphenous vein (GSV) were treated with either the VenaSeal closure system (VenaSeal SCS) or radiofrequency ablation (RFA) therapy.

NCT00940095
The aim of this study is to demonstrate that clazosentan, administered as a continuous intravenous infusion at either 5 mg/h or 15 mg/h until Day 14 post aneurysmal subarachnoid hemorrhage (aSAH), reduces the incidence of cerebral vasospasm-related morbidity and all-cause mortality within 6 weeks post-aSAH treated by endovascular coiling. The primary endpoint of the study is the occurrence of cerebral vasospasm-related morbidity, and mortality of all-causes within 6 weeks post-aSAH, defined by at least one of the following: 1. Death (all causes). 2. New cerebral infarct(s) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 3. Delayed ischemic neurological deficit (DIND) due to cerebral vasospasm as either the primary or relevant contributing cause, or not adjudicated to be entirely due to causes other than vasospasm. 4. Administration of a valid rescue therapy in the presence of confirmed cerebral vasospasm on angiography (DSA or CTA). An independent Critical Events Committee (CEC) will adjudicate whether or not patients meet the primary endpoint and its individual morbidity components.
NCT01985126
The purpose of this study is to evaluate the efficacy and safety of 2 daratumumab treatment regimens in participants with multiple myeloma who have received at least 3 prior lines of therapy (including a proteasome inhibitor \[PI\] and immunomodulatory drug \[IMiD\]) or are double refractory to a PI and an IMiD.
NCT01568736
The hyper IgD syndrome (HIDS) is an inflammatory disease caused by mevalonate kinase deficiency. There is no cure, and available treatments of HIDS febrile episodes have shown limited clinical efficacy. The development of effective interventions for HIDS is limited by our poor understanding of the disease. The goal of the study is to better characterize the inflammatory response during HIDS episodes and to determine the relationship between this response and blood and urine markers of mevalonate kinase deficiency. This knowledge will help us learn more about the cause of the disease and should lead to the identification of new disease biomarkers that can be used to evaluate clinical efficacy in future therapeutic trials. The primary hypothesis is that the costimulatory B7 glycoprotein abnormalities identified in the murine MKD model will be recapitulated in sera obtained from human HIDS patients, either before, during or after febrile episodes. The secondary hypothesis is that B7 glycoprotein molecule levels will correlate with clinical symptomatic severity score, other known biomarkers of HIDS, markers of inflammation and or markers of isoprenoid metabolism.
NCT02799784
