NCT ID: NCT03139006 Recruiting - Clinical trials for Cardiovascular Diseases

Application of speCtraL Computed tomogrAphy to impRove specIficity of Cardiac compuTed tomographY

CLARITY
Start date: March 29, 2017
Phase:
Study type: Observational [Patient Registry]

Cardiovascular disease remains the leading cause of morbidity and mortality worldwide. Coronary computed tomography angiography (CCTA) and, if indicated, invasively measured fractional flow reserve (FFR) is currently used for ruling out significant coronary artery disease. FFRCT is a novel non-invasive technique in which FFR is derived from CT images, however this method is currently, just like CCTA, lacking specificity. Spectral Detector CT (SDCT) is a novel technique whereby a spectrum of monoenergetic images at different kiloelectron Volt (keV) values (40 to 200 keV) can be reconstructed. By using these monoenergetic images, a decrease in blooming and beam-hardening artifacts could be achieved. In addition, SDCT offers the opportunity to assess myocardial iodine distribution and quantification. When combining these factors, we hypothesize more accurate information will be available about the coronary anatomy, degree of stenosis and FFRCT and thereby contribute to a more accurate way for the detection of hemodynamic significant stenosis. Therefore, the aim of this study is to assess the accuracy of SDCT as a non-invasive way for the detection of hemodynamically significant coronary artery stenosis. Objective: The overall objective of this project is to assess the accuracy of SDCT for the detection of flow limiting stenosis in the coronary arteries using invasive FFR as the standard of reference. Whereby different sub-aims (e.g. improvement of FFRCT) are made to answer the overall objective. The secondary objective is to determine the decrease of calcium blooming of calcifications and beam-hardening artifacts and the improvement of myocardial blood volume quantification on SDCT in comparison with conventional CT.

NCT ID: NCT03138512 Completed - Clinical trials for Carcinoma, Renal Cell

A Study Comparing Nivolumab, Nivolumab in Combination With Ipilimumab and Placebo in Participants With Localized Kidney Cancer Who Underwent Surgery to Remove Part of a Kidney

CheckMate 914
Start date: July 7, 2017
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether nivolmab alone or the combination of nivolumab and ipilimumab versus placebo, is safe and effective for delaying or preventing recurrence of cancer in participants who have experienced partial or entire removal of a kidney.

NCT ID: NCT03138434 Terminated - Clinical trials for Abdominal Aortic Aneurysm

Advanced MRI in AAA

Start date: April 12, 2017
Phase:
Study type: Observational

This study aims to determine whether advanced MRI sequences can provide robust and clinically relevant information about abdominal aortic aneurysms (AAAs). The MRI sequences will study outcomes related to blood flow inside AAA, microvasculature of the AAA vessel wall and intraluminal thrombus inside AAA. Robustness of these MRI sequences will be determined with testing of feasibility and reproducibility. Clinical relevance will be assessed by studying the association between the primary outcomes and disease severity. Disease severity will be expressed by AAA diameter. It is our hypothesis that these parameters are significantly related to disease severity and may therefore be future markers of disease progression.

NCT ID: NCT03138096 Completed - Malaria,Falciparum Clinical Trials

Safety and Protective Efficacy of Pb(PfCS@UIS4)

PbVac
Start date: May 29, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

In the underlying study, a genetically modified P. berghei parasite is used. P. berghei is one of the four Plasmodium species that causes malaria in rodents. The hypothesis is that immunization of humans with P. berghei will induce a cross-species immune response without the risk of a breakthrough infection. To further increase the potential for protective efficacy, the P. falciparum circumsporozoite (CS)- protein gene has been integrated in the P. berghei parasite, generating a genetically modified P. berghei parasite, abbreviated as Pb(PfCS@UIS4).

NCT ID: NCT03138083 Terminated - Neoplasms Clinical Trials

OMO-1 in Solid Malignancies

Start date: August 8, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

This is a modular, first time in patient, open-label, multicentre study of OMO-1, administered orally, alone and in combination with anti-cancer treatments, in patients with locally advanced, unresectable or metastatic solid malignancies.

NCT ID: NCT03136926 Recruiting - Antifungal Agents Clinical Trials

Screening Anti-Fungal Exposure in Intensive Care Units

SAFE-ICU
Start date: January 2017
Phase:
Study type: Observational

Adequate antifungal therapy is a critical determinant of survival in patients admitted to an Intensive Care Unit (ICU) with suspected or proven fungal infections. Critical illness can alter the way human body handles antifungal agents, i.e. how the drugs are distributed in the body and removed from the body. Consequently, these changes can increase the risk of inappropriate antifungal exposure that may lead to adverse consequence on patients' outcome. Developing an evidence-based antifungal dosing guideline is of global significance and should be considered a priority to improving clinical outcomes for patients receiving antifungal agents The aim of the SAFE-ICU Study is to develop optimised antibiotic dosing guidelines for ICU patients with life-threatening infections that account for patient characteristics. This will be achieved through completion of the following aims: i) Describe detailed demographic, clinical and plasma antibiotic concentration-time data in a large ICU patient cohort; ii) Perform a robust statistical analysis of the data collected in Aim 1 to develop an enhanced preliminary prediction algorithm for antifungal dosing. This is a multi-national study and will enrol ICU patients who are prescribed an antifungal agent (fluconazole, voriconazole, posaconazole, isavuconazole, caspofungin, anidulafungin, micafungin or amphotericin B). A minimum of 12 patients per drug will be enrolled across at least 15 countries and up to 80 ICUs. Eligible patients are those admitted to the ICU, who are prescribed an antifungal agent (fluconazole, voriconazole, posaconazole, isavuconazole, caspofungin, anidulafungin, micafungin or amphotericin B). Blood samples will be taken to measure drug concentration. Sampling will occur on two occasions, first during study days 1-3 and then a second time between days 4-7, each over an 8-24 hour period. Blood samples will be taken from a vascular access device already inserted for ICU patient care. Abdominal samples from abdominal indwelling drains already inserted peri operatively will also be collected on these two occasions in the subgroup of patients with intra-abdominal infection. Data on infection, various blood tests and patient specific data will be collected using a structured case report form (CRF). Patients will also be followed up 30 days after enrolment into the study to evaluate 30-day mortality. Collected samples will be frozen and stored locally and then shipped in large batches for processing at Burns Trauma and Critical Care Research Centre, The University of Queensland, Australia. Data analysis for development of antifungal dosing algorithms will also be undertaken at The University of Queensland, Australia.

NCT ID: NCT03136640 Completed - Clinical trials for Castration-resistant Prostate Cancer

ModraDoc006/r in Metastatic Castration-resistant Prostate Cancer

Start date: April 26, 2017
Phase: Phase 1
Study type: Interventional

This is a safety, feasibility and pharmacokinetic study to confirm that the recommended safe dose and schedule of ModraDoc006/r (oral docetaxel with ritonavir) as determined in a previous phase I study is also safe and feasible in the target population of patients with CRPC.

NCT ID: NCT03135457 Completed - Clinical trials for Transfusion-associated Circulatory Overload

TACO Crossover TRIAL

Start date: August 16, 2017
Phase: N/A
Study type: Interventional

This is an open-label, prospective crossover randomized controlled trial to investigate wether TACO is solely hydrostatic pressure overload or arises from a combination of hydrostatic pressure overload and capillary leakage, by investigating the difference in change in static pressure parameters (PCWP), dynamic volume parameters (PICCO) as indirect measurements of volume status and capillary leakage after autologous transfusion or saline infusion. The investigators will estimate effective circulating volume following autologous transfusion or saline infusion. Furthermore, the investigators will investigate the effect of fluid loading on the microcirculation.

NCT ID: NCT03134846 Recruiting - Clinical trials for Head and Neck Squamous Cell Carcinoma

Image Guided Surgery for Margin Assessment of Head and Neck Cancer Using Cetuximab-IRDye800CW cONjugate

ICON
Start date: December 16, 2017
Phase: Phase 1/Phase 2
Study type: Interventional

Surgery remains a main pillar in the treatment of head and neck squamous cell carcinoma (HNSCC). The margin status is the main prognostic factor of local tumor control in surgically treated HNSCC and will determine the postoperative treatment strategy. A margin of ≤1 mm of normal tissue is considered a positive margin and requires either a re-operation or postoperative chemoradiation with a combination of cisplatin and 5-FU, which substantially increases morbidity. Margins wider than 1 mm but less than 5 mm require re-operation, or, if that is not possible, post-operative radiotherapy without the concomitant use of chemotherapy. Currently, no technology is available in the operating room, which reliably supports tumor excision in terms of margin status. In fact, surgeons can only combine pre- operative imaging data with tactile and visual information during surgery for assessing tumor margins with limited accuracy. With the introduction of molecular imaging techniques using near infrared (NIR) fluorescent optical contrast agents coupled to targeted compounds, new avenues have opened up for intra-operative assessment of tumor margins. Tracers are based on antibodies directed against Vascular Endothelial Growth Factor-A, i.e. bevacizumab-IRDye800CW, in patients with breast cancer or against Epidermal Growth Factor Receptor, i.e. cetuximab-IRDye800CW, in patients with HNSCC. First trials have shown that systemic administration of these compounds is safe and tumor specific. These findings prompted us to design this innovative application in a clinical trial for the intraoperative assessment of tumor margins during surgical treatment of HNSCC using cetuximab-IRDye800CW.
