NCT ID: NCT06051253 Recruiting - Crohn Disease Clinical Trials

TDM-based Infliximab Treatment for Active Perianal Fistulizing Crohn's Disease

Start date: November 1, 2023
Phase: Phase 4
Study type: Interventional

This study will compare the efficacy and safety of TDM (therapeutic drug monitoring)-based infliximab (CT-P13, RemsimaTM) intravenous therapy compared with the standard infliximab (RemsimaTM) intravenous therapy for patients with active perianal fistulzing Crohn's disease.

NCT ID: NCT05942157 Recruiting - Sepsis Clinical Trials

Therapeutic Drug Monitoring in Patients With Difficult-to-Treat Gram-Negative Bacterial Infections

TDM-RCT
Start date: March 29, 2023
Phase: N/A
Study type: Interventional

A prospective, open-label, randomized controlled trial will be conducted to evaluate a novel TDM-guided therapy in management of DT-GNB infections. We hypothesize that TDM-guided antibiotic therapy will reduce 14-day all-cause mortality by 6% (absolute risk reduction) in septic patients with DT-GNB infections, when compared to standard therapy. TDM for 11 antibiotics will be performed for all trial patients although test information will be withheld for the standard therapy arm. The primary aim is to compare the 14-day all-cause mortality rates of novel TDM-guided antibiotic dosing versus standard therapy.

NCT ID: NCT05926518 Completed - Critical Illness Clinical Trials

Anti-Xa Level With Thromboprophylactic Dosage Nadroparin in Critically Ill COVID-19 and Non-COVID-19 Patients

NADRO
Start date: November 1, 2020
Phase:
Study type: Observational

Primary objective The objective of this study is to compare anti-Xa levels obtained with a standard high dose thrombosis prophylaxis in COVID-19 intensive care-patients compared with anti-Xa levels obtained with a normal dose thrombosis prophylaxis in non-COVID-19 intensive care patients. Secondary objectives 1. To determine the incidence of anti Xa levels out of range of the established target anti Xa level in both groups. 2. To determine the influence of relevant co-variates on the anti-Xa level in the COVID-19 and non-COVID-19 group.

NCT ID: NCT05542771 Recruiting - Critical Care Clinical Trials

External Validation of the Beta-lactam Target Non-attainment (BATMAN) Risk Score in Adult ICU Patients: a Diagnostic Multivariate Predictive Risk Model

BATMAN
Start date: April 24, 2023
Phase:
Study type: Observational

Intensive care (IC) patients regularly get infections. Sometimes it is even the reason of admission to the intensive care unit. To treat these infections, we give medicines called antibiotics, such as β-lactams antibiotics. Every IC patient receives the same dose of β-lactams antibiotics, while we know this can lead to undertreatment in some IC patients. The BATMAN risk score was created to predict which IC patient is undertreated. This study aims to validate the BATMAN risk score so it can be used in clinical practice.

NCT ID: NCT05283174 Recruiting - Clinical trials for Therapeutic Drug Monitoring

The Association Between Non-vitamin K Antagonist Oral Anticoagulant Therapy and Acute Stroke Severity and Post Stroke Short-term and Long-term Outcomes.

Start date: February 25, 2022
Phase:
Study type: Observational

Non-vitamin K antagonist oral anticoagulant (NOAC) is the first line therapy to prevent thromboembolism in atrial fibrillation (AF) patients. Previous investigation showed that preceding NOAC therapy was associated with lower severity of ischemic stroke, but with higher in-hospital mortality in intracerebral hemorrhage (ICH), as compared with antithrombotic agent non-users. Measurement of NOAC level upon acute stroke aids the critical decision of acute management. Real-world data regarding the relationship between the NOAC adherence, the appropriateness of NOAC regimen, or NOAC level in acute stroke and the stroke severity or short-term outcome is lacking. Further, optimal selection for long-term stroke prevention among patients with acute stroke during NOAC therapy remains unclear. Specific purpose: To analyze the association between NOAC adherence or NOAC level upon acute stroke and stroke severity or stroke outcomes, and analyze the impact of starting or withholding antithrombotic therapy after acute stroke on long-term stroke outcomes. Specific Aim (Year 1): To investigate the relationship between NOAC adherence or appropriateness of NOAC dose and acute stroke severity or in-hospital mortality based on National Health Insurance Research Database (NHIRD). Another important goal is to prospectively establish a cohort of AF users who developed acute stroke during NOAC therapy in National Taiwan University Hospital (NTUH) (target: around 100 patients annually), measure the NOAC level upon hospital arrival, record stroke severity, 90-days functional outcomes, post-stroke antithrombotic agents and repeat stable NOAC level in patients who restart NOAC treatment. Specific Aim (Year 2): To investigate the relationship between post-stroke antithrombotic therapy, especially changing or retaining preceding NOAC and long-term stroke outcomes based on NHIRD. We will also keep enrolling the prospective cohort and follow the 1-year stroke outcome. Specific Aim (Year 3): To complete the process of study enrollment (total: 300 patients) and conduct statistical analysis. The main goal is to finish the Aim 1 and 2 based on NHIRD. In addition, to provide data of emergent NOAC level and stroke severity or short-term outcome, and post-stroke antithrombotic therapy and long-term outcomes based on the prospectively enrolled cohort.

NCT ID: NCT05275179 Completed - Critical Illness Clinical Trials

Pharmacokinetic of Posaconazole in Critically Ill Patients

Start date: February 11, 2021
Phase:
Study type: Observational

The posaconazole pharmacokinetic in critically ill patients will be studied in a prospective, non-interventional, monocentric observational trial.

NCT ID: NCT05259228 Recruiting - Pharmacokinetics Clinical Trials

Therapeutic Drug Monitoring of Tyrosine Kinase Inhibitor in Patients With Chronic Myeloid Leukemia

Start date: December 1, 2022
Phase:
Study type: Observational

Chronic myeloid leukemia (CML) consists of 3 clinical stages including chronic phase, accelerated phase and blast crisis. Patients may only survive for few more days to weeks once the disease progresses to blast crisis, even though they might have been stable for several years in the chronic phase. The standard treatment, continuous use of tyrosine kinase inhibitors (TKIs), improves long-term survival, and even may help patients achieve complete remission. Four TKIs are reimbursed by National Health Insurance in Taiwan. Among them, imatinib, nilotinib as well as dasatinib, and ponatinib are the first, second and third generations of TKIs, respectively. Many factors influence the disease control of CML, such as TKI type, genetic mutation and medication adherence. Only 69% of patients followed their physicians' recommendations in a local survey. The medication adherence of TKIs was compromised based on several clinical studies domestically and worldwide due to the slow progression in the chronic phase. Patients might hold or decrease the dose of TKIs on their own when they suffer side effects. Furthermore, the significant intra-subject variations of TKI plasma concentration and drug-drug and drug-food interactions which alter the metabolism of TKIs may lessen therapeutic effect and patient safety. Therefore, this study aims to develop and validate analytic methods of imatinib, dasatinib, nilotinib and ponatinib plasma concentrations. The investigators plan to build the pharmacokinetic models of these 4 TKIs and analyze the impacts of meals, adherence, hepatic enzyme inhibitors and inducers, antacids, proton pump inhibitors and H2 blockers, etc. Adverse drug reactions and treatment outcomes will be evaluated to determine the availability and feasibility of therapeutic drug monitoring of TKIs as part of routine service in pharmacist-led clinics.

NCT ID: NCT04496024 Recruiting - Clinical trials for Bone and Joint Infection

Ofloxacin Concentration-toxicity Relationship in the Elderly

ROSCO
Start date: June 2, 2020
Phase: N/A
Study type: Interventional

Ofloxacin is a gold standard antibiotic for the treatment of bone and joint infections due to sensible staphylococcus strains. However, in the elderly, inter-individual variability of the pharmacokinetics may reduce the efficacy or increase toxicity. The occurrence of ofloxacin side effects is likely to be increased in case of higher exposition. However, the serum concentration-toxicity relationship has not yet been determined. The purpose of this project is to assess the association between the residual serum concentration of ofloxacin at day 3 and the occurrence of at least one adverse effect attributable to ofloxacin, and determine a threshold toxicity concentration if this association exists.

NCT ID: NCT04132115 Recruiting - Clinical trials for Subarachnoid Hemorrhage

Optimized Antibiotic Therapy in Patients With Subarachnoid Haemorrhage (ES) and Cerebral Haemorrhage (EC)

TANDEM
Start date: October 1, 2019
Phase:
Study type: Observational

A recent prospective observational clinical study conducted in an intensive care unit of a third level US university hospital showed that 94% of patients with ES and 50% of those with EC had an ARC for a duration of at least one day during the hospital stay. Although there is currently a great deal of evidence describing ARC in various subgroups of critically ill patients, on the other hand there is little documentation regarding the effect that ARC can have on exposure to renally eliminated drugs. Therefore, the aim of this study is to prospectively evaluate the proportion of plasma under-exposure to hydrophilic antimicrobials in patients with ES or EC and with ARC, in order to verify whether the recommended dosage regimens for these drugs are adequate for reaching the pharmacodynamic targets of therapeutic efficacy.

NCT ID: NCT03790631 Recruiting - Efficacy Clinical Trials

The OPTIMAL TDM Study: Determining Optimal Beta-lactam Plasma Concentrations Through Therapeutic Drug Monitoring

OPTIMAL TDM
Start date: January 14, 2019
Phase:
Study type: Observational

Little is known of beta-lactam antibiotics' true therapeutic plasma concentration range. The aims of this study are to define evidence-based, safe and effective upper and lower limits of the plasma concentrations of imipenem, meropenem, amoxicillin, flucloxacillin, piperacillin, ceftazidime and cefepime in patients at increased risk of serious bacterial infections and currently understudied pharmacokinetics (the critically ill, the elderly, and the immunosuppressed). This prospective observational study will include adult patients with suspected or confirmed systemic bacterial infection receiving one of the above-named antibiotics and hospitalized in intensive-care, step-down, or hematology-oncology units of the Geneva University Hospitals (HUG). Eligible patients will be identified via the electronic health record (EHR). Patients receiving traditional intermittent dosing or prolonged infusions will undergo TDM for at least one intermediate (mid-interval) and one trough level at 24 hours (-12 or +48 hours) after the therapy's start. Patients receiving continuous infusions will undergo TDM for at least one steady-state level. Clinical course will be observed for 30 days from the start of the study antibiotic (1st day of study antibiotic =day 1). The primary outcome is incidence of clinical toxicity through day 30 after start of study antibiotic (as stratified by BL trough concentration). Secondary outcomes are listed below.
