Active clinical trials for "Hemostatic Disorders"

EFISS is a prospective, randomized, placebo-controlled trial testing the feasibility, safety and efficacy of prophylactic administration of fibrinogen in paediatric spinal surgery. The study is monocentric and will be conducted in University Hospital Brno, Czech Republic. This is a pilot study in which the primary objective will be to evaluate the feasibility of a clinical trial in 32 selected patients undergoing scoliosis surgery. Participants will be randomized into study groups in a 1:1 allocation ratio and followed up for 28 days after surgery. The expected duration of this clinical trial is 8 months.

Up to 5% of Atrial Fibrillation (AF) patients may have or develop contraindications to use oral anticoagulation (OAC). Randomized controlled trial (RCT) data suggest that Left Atrial Appendage Occlusion (LAAO) may provide a non-inferior alternative for cardioembolic stroke protection in patients tolerant to OAC. However, RCT data for LAAO is lacking in patients with contra-indications to OAC using antiplatelet (APT) or no therapy as usual care. The hypothesis underlying this trial is to demonstrate that LAAO is superior to usual care for the prevention of stroke.

Palonosetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of palonosetron. The investigators therefore will perform the present study to measure the effect of palonosetron levels using thromboelastography.

The quality of the reversion of these serious hemorrhagic accidents under oral anticoagulants depends on the adequate use of reversion products but also on the speed of obtaining hemostasis data allowing to evaluate the effectiveness of this "chemical" hemostasis. . Clot formation can be studied using different visco-elastic methodologies (thromboelastography or thromboelastometry) with a detectable change in clot formation with oral anticoagulants. These techniques have been proven in patients who are often unstable and present with severe trauma with hemorrhagic shock, thus making it possible to guide the transfusion protocol. However, the level of recommendations in these patients, who are often polyhydrated and poly-transfused, is grade 1c due to small-scale studies with difficulty in analyzing the values of the visco-elasticity parameters in these patients. In addition, these methods are little used in current practice because of their difficult reading. The use of visco-elastic methods in patients on oral anticoagulants has been little studied. However, taking an oral anticoagulant mainly causes coagulation disorders. The use of these methods would make it possible to assess the impact of the anticoagulant on hemostasis and to verify the correct reversion of hemostasis parameters. Quantra®, one of the visco-elastic methods, would make it possible to speed up the evaluation in the context of biology relocated to the patient's bed with a simplified reading of the factors involved in the formation of the clot in order to allow an immediate evaluation the quality of the reversion performed which may have an impact on the re-administration of reversion products or even an adaptation of the dose of reversion products according to the initial parameters at the time of severe bleeding before reversion. The objective of this pilot study is to study the metrological evolution, before and after reversion, of the hemostasis parameters evaluated by the Quantra® system from HemoSonics in a patient being his own control in the context of a severe hemorrhage occurring on oral anticoagulants (VKA or DOA).

The aim of this ex-vivo study is to quantify the effect of tramadol on platelet aggregation.

Ondansetron may alter whole blood coagulation. However, little is known about the dose-response relationships according to the blood concentration of ondansetron. The investigators therefore will perform the present study to measure the effect of ondansestron on the blood coagulation pathway according to the drug concentration level using a thromboelastography test.

SPK-8016 is in development for the treatment of patients with inhibitors to FVIII. This Phase 1/2, open-label, non-randomized, dose-finding study is part one of a planned two part study of SPK-8016. Part one will evaluate the safety, efficacy, and tolerability of SPK-8016 in adult males with clinically severe hemophilia A and no measurable inhibitor against FVIII. Data obtained from Part 1 will inform the study design and dose selection for Part 2 in patients with FVIII inhibitors.

This study will find the maximum tolerated dose (MTD) of CYNK-001 which contain NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given post Autologous Stem Cell Transplant (ASCT). The safety of this treatment will be evaluated, and researchers will want to learn if NK cells will help in treating Multiple Myeloma.

This trial is conducted globally. The aim of the trial is to investigate the safety and efficacy of turoctocog alfa pegol (N8-GP) in previously untreated patients (PUPs) with haemophilia A.

Cesarean delivery has become the most common surgical procedure in the US. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to improve the quality of post-cesarean analgesia and markedly reduce opioid consumption. The effect of NSAIDs on healthy volunteers results in inhibition of platelet aggregation and prolonged bleeding time. However, in the obstetric population, the presence and degree of platelet inhibition after NSAID exposure is less clear. The investigators plan to use Platelet Aggregometry and Thromboelastography (TEG) to evaluate the effect of ketorolac on platelets.
