NCT ID: NCT03489577 Terminated - Sepsis Clinical Trials

The Role of Post-traumatic Inhibition of the Innate and Adaptive Immune System in the Development of Infectious Complications in Severely Injured Patients

Start date: June 2014
Study type: Observational

Patients admitted to the Intensive Care Unit after severe injury are prone to suffer from infectious complications and even sepsis. Despite tremendous efforts the etiology of this increased susceptibility to infectious pathogens is incompletely understood. Clinical signs and symptoms as well as current diagnostic clinical tests (WBC, CRP, cytokines, interleukines) lack sensitivity or specificity for adequate prediction of the development of infectious complications or sepsis. Neutrophil granulocytes, cells of the innate immune system, play an important role in the defence against invading bacterial pathogens and are crucial in preventing fulminant infections. For successful eradication of a bacterium neutrophils need to exert specific functions: chemotaxis, migration, phagocytosis, degranulation and production of radical oxygen species. Much research has focused on the effect of trauma on neutrophil's individual capacities to kill bacteria with conflicting interpretations as a result. For adequate determination of the neutrophil's capacity to eradicate bacteria from tissue of trauma patients we developed novel in-vitro assays in which neutrophils are tested for all of these functions combined. This assay allows us to identify dysfunctional neutrophils adequately. The main focus of this study is the determination of the functionality of aberrant neutrophils circulating in the peripheral blood of severly injured following trauma.

NCT ID: NCT03334383 Terminated - Colon Carcinoma Clinical Trials

Trial for Retractor Sponge Evaluation in Laparoscopic Colorectal Surgery

Start date: January 2015
Phase: N/A
Study type: Interventional

Laparoscopic surgery of the distal colon and rectum requires surgery with an appropriate field of view. A commonly used technique to create a clear exposure is the steep Trendelenburg position in which the patient is positioned in an angle of 15 to 40 degrees with the head down using the effect of gravity to retract the small intestine. This method is associated with haemostatic changes caused by the cranial shift of abdominal organs and blood. Recently, a cellulose compressed sponge was developed as intraoperative retractor, with the aim to keep the small intestines aside while the patient remains in a horizontal position. The safety of the sponge is secured with CE marking. The retractor sponge ensures a clear surgical field and potentially prevents haemostatic instability by avoiding Trendelenburg position. A pilot study in the St Antonius Hospital Nieuwegein has shown that use of the sponge might be associated with shorter hospital stay.

NCT ID: NCT03075228 Terminated - Obesity Clinical Trials

Comparison of the Microbial Composition in Lean and Obese Subjects

Start date: April 25, 2017
Phase: N/A
Study type: Observational

Rationale: The microbial composition in the small intestine (SI) differs largely from the composition in feces. Many physiological processes related to health, such as immunoregulation and metabolic programming, mainly take place in the SI. Therefore, the SI, from a microbiota perspective, is as relevant as the large intestine. There are indications that microbiota composition is different in lean and obese subjects, and is related to insulin resistance. However, these indications are mainly based on the analysis of fecal samples. Therefore, analysis of the microbiota composition in the more proximal part of the gastrointestinal (GI) tract may provide new insights into the microbial species that are involved or related to metabolic homeostasis at that location. The IntelliCap® CR system offers a minimally invasive tool that is able to collect reliable samples in the SI, as was shown by NIZO in a clinical validation study. The main aim of the current study is to explore and compare the upper GI microbiota composition in lean and obese subjects, in order to generate new leads for development of products that may target the upper GI microbiota community or specific species thereof, which may impact the maintenance of metabolic homeostasis. This may provide new opportunities for the treatment, reduction or prevention of overweight and/or obesity or insulin resistance.

Start date: March 14, 2017
Phase: Phase 2
Study type: Interventional

This is a single-arm, multicenter, Phase 2 study to evaluate the efficacy and safety of the combination regimen of daratumumab plus durvalumab (D2). The study will consist of 2 parts; Part 1 has a 2-stage design while Part 2 consists of an expansion phase. Subjects will receive intravenous (IV) DARA at 16 mg/kg on the same dosing schedule (weekly [QW], every 2 weeks [Q2W] or every 4 weeks [Q4W] of each 28-day cycle) received on their last prior therapy containing DARA. The dosing schedule for DARA may be adjusted during the course of the study as outlined in the protocol. Subjects will also receive IV DURVA at 1500 mg on Day 2 (Cycle 1) and on Day 1 (Cycles ≥ 2) of each 28-day treatment cycle.

NCT ID: NCT02927431 Terminated - Virus Diseases Clinical Trials

Study to Evaluate the Efficacy and Safety of Danirixin Co-administered With Oseltamivir in the Treatment of Adults Hospitalized With Influenza

Start date: January 19, 2017
Phase: Phase 2
Study type: Interventional

Danirixin (DNX) is a novel, selective, and reversible antagonist of the C-X-C chemokine receptor (CXCR) 2 and has been shown to decrease neutrophil transmigration and activation to areas of inflammation. An intravenous (IV) formulation of DNX hydrobromide (HBr) is being developed as an anti-inflammatory agent for treatment of adults hospitalized with influenza (IFV). While early therapy with antivirals decreases severity and duration of symptoms of influenza, there are no drugs that have demonstrated clinical efficacy in randomized clinical trials in this population. Current treatment guidelines for hospitalized IFV recommend neuraminidase inhibitors as standard of care therapy. IFV studies in animals have demonstrated that therapeutic treatment with the combination of a CXCR2 antagonist and a neuraminidase inhibitor reduced lung neutrophils and showed trends for improvements in clinical scores, lung function and pathology with no evidence of worsening outcomes, including viral load. This Phase 2, randomized, double-blind (for IV DNX), placebo-controlled (for IV DNX) 3-arm study will be the first study to determine the efficacy and safety of IV DNX when co-administered (in all groups) with standard of care antiviral treatment (open-label oral oseltamivir [OSV]) in subjects hospitalized with IFV. The primary objective of the study is to assess the efficacy of treatment with IV DNX twice daily given with oral OSV compared to oral OSV twice daily on time to clinical response (TTCR). In this study, subjects will be randomized in a 2:2:1 ratio to 15 milligram (mg) free base equivalent (FBE) IV DNX, 50 mg FBE IV DNX, or matching placebo twice daily. All subjects will also receive open-label 75 mg oral OSV, twice daily (given as standard of care). The study treatment duration will be for up to 5 days. The investigator may elect to continue treatment with OSV after 5 days of study treatment. Follow up will continue until Day 45 for all subjects. The study will begin with enhanced safety monitoring in sentinel cohorts, leading to stepwise enrollment of subjects. Subjects will be enrolled based on increasing levels of renal impairment, and less severe hospitalized subjects will be enrolled prior to enrollment of critically ill subjects, as this is the first study conducted in the hospitalized population with severe IFV. Approximately 300 subjects are targeted to be enrolled in the study.
