NCT ID: NCT04052776 Completed - Clinical trials for Spinal Cord Injuries

Acute Effects of Pharmacological Neuromodulation on Leg Motor Activity in Patients With SCI Treated With EES

STIMO-PHARMA
Start date: September 11, 2020
Phase: Phase 1
Study type: Interventional

In a current first-in-man study, called Stimulation Movement Overground (STIMO) (NCT02936453; CER-VD: 04-2014; Swissmedic: 2016-MD-0002), epidural electrical stimulation (EES) of the spinal cord is applied to enable individuals with severe spinal cord injury (SCI) to complete intensive locomotor neurorehabilitation training. In this clinical feasibility study, it was demonstrated that EES results in an immediate enhancement of locomotor functions and that when applied repeatedly as part of a neurorehabilitation program, EES can progressively improve leg motor control in individuals with severe SCI. Mechanistically, EES acts trans-synaptically upon spinal circuitries through the electrical stimulation of proprioceptive fibers. It is assumed that this stimulation does not increase the level of availability of monoamine neurotransmitters below the SCI level, which are essential for lower extremity movement generation. Specifically, in a non-injured individual, dopamine and serotonin synthesized in the brain and brainstem are released by fibers diffusely innervating the spinal cord, serving to critically mediate excitability of motor neurons and interneurons in lumbar and sacral spinal level. Spinal cord injury would partially or entirely disrupt these modulation pathways, resulting in a detrimental lack of crucial neurotransmitters below the injury level. This lack of endogenous neurotransmitters could potentially be compensated for by pharmacological agents promoting the neurochemical environment necessary for locomotion.

NCT ID: NCT04052009 Recruiting - Clinical trials for Incomplete Spinal Cord Injury

Locomotor Training in Individuals With Incomplete Spinal Cord Injury. A Pilot Study

Start date: September 24, 2019
Phase: N/A
Study type: Interventional

Background: In Switzerland, about 6000 individuals live with the consequences of a spinal cord injury (Brinkhof et al, 2016). One of the major goals after an incomplete spinal cord injury (iSCI) is to regain walking function. To this end, different approaches are used in rehabilitation such as treadmill-based, robotic-assisted (exoskeleton or end-effector) and conventional gait training. According to current literature, the superiority of one of these approaches remains unclear (Mehrholz, Harvey, Thomas, and Elsner, 2017); In the research on gait rehabilitation after iSCI, recent randomized clinical trials (RCTs) found no statistical differences between conventional gait training and robotic-assisted gait training. Nevertheless, according to the comparison of effect sizes obtained from these training, these trials suggested that the conventional training approach leads to larger improvements in gait capacity when compared to robotic-assisted therapy (Field-Fote and Roach, 2011; Nooijen, Ter Hoeve, and Field-Fote, 2009). Therefore, these trials highly recommended further research considering these aspects. However, in clinical settings, the implementation of such systematic and intense training sessions remains challenging. The present study aims to test the hypothesis that conventional training might have larger effect sizes on gait capacity and to evaluate the feasibility of such systematic training in a clinical setting of inpatient rehabilitation. Objectives: To contribute to the current knowledge on best clinical practice in gait rehabilitation within the iSCI population. More specifically, the study objectives are two-fold: A first objective is to compare the effects of conventional training, end-effector based therapy and the combination of these interventions on the gait ability of iSCI. A second objective is the evaluation of the feasibility of systematic gait training protocols in a clinical setting. Participants: Individuals with motor incomplete spinal cord injury (iSCI), presenting a traumatic or non-traumatic iSCI with an injury onset <6 months. Intervention: Participants will be trained in one of the three groups by trained physical therapists during 10 sessions, 3x/week with an average duration of 30 minutes. Outcomes: To attain the first objective the effects will be quantified by the following main outcomes: Walking capacity (independence), walking speed, and safety. Feasibility of the systematic intervention will be evaluated using the drop-outs of therapy interventions.

NCT ID: NCT04049994 Completed - Clinical trials for Spinal Cord Injuries

Immunomodulation Therapy for Urinary Tract Infections

UROVAXOM-P
Start date: June 1, 2020
Phase: Phase 4
Study type: Interventional

Urinary tract infections (UTI) represent one of the most common morbidities in individuals with spinal cord injury (SCI) and reason for re-hospitalization. The consequences of recurrent UTI are a decrease in quality of life and considerable health costs. Immunomodulation therapy with UroVaxom is a very promising method for the prevention of UTI, however data in individuals with SCI are very limited. The primary objective of this pilot study is to evaluate the feasibility (recruitment rate, patient attrition, compliance, assessment procedures etc.) of a main trial. A secondary objective is to collect data for an informed sample size calculation. Furthermore, the clinical and biological changes after immunomodulation therapy will be investigated. This is a randomized, placebo-controlled, mono-centric pilot study investigating the feasibility of a main trial regarding the effectiveness of immunomodulation with UroVaxom in the prevention of UTI and the effect on the immune system in individuals with acute SCI during primary rehabilitation. There will be two parallel groups of 12 participants each. Group allocation will be based on a block-randomization stratified according to sex. Study participants and outcome assessors will be blinded to the group allocation. The nursing staff will be unblinded and will administer the treatment and the placebo. Study participants will either receive Uro-Vaxom (one tablet / day) or an off-the-shelf placebo for 90 days. After termination of the treatment, the study participants will be followed for 12 months. Blood and urine samples will be taken before and 90 days, 6 months and 12 months after treatment start.

NCT ID: NCT04049110 Completed - Clinical trials for Diabetes Mellitus, Type 1

Dapagliflozin in Physical Exercise in Type 1 Diabetes

Start date: August 25, 2020
Phase: Phase 3
Study type: Interventional

Inhibitors of sodium-dependent glucose-transporter 2 (SGLT-2 inhibitors, including dapagliflozin) inhibit glucose reabsorption in renal tubular cells, hereby increasing glycosuria in the hyperglycemic state. Its mechanisms of action are independent of insulin, which makes SGLT-2 inhibitors a potential adjunct to insulin in type 1 diabetes mellitus (T1DM). However, a higher risk for diabetic ketoacidosis (DKA) was reported in patients with T1DM taking SGLT-2 inhibitors. DKA depends on an accumulation of ketone bodies in the blood stream, which equals an accumulation of acids that lead to acidosis. The underlying mechanisms of this observation are unknown. Ketone body production depends on the molar ratio of glucagon to insulin, with insulin suppressing but glucagon stimulating ketone body production. This translates into higher production during relative insulin deficiency, carbohydrate deficiency, and prolonged fasting, which occurs during sickness but also physical exercise. Physical exercise is a recommended cornerstone in the treatment of T1DM and current treatment guidelines recommend both, reductions of insulin doses and ingestion of additional carbohydrates to avoid hypoglycemic events. These adaptions might increase relative insulin deficiency, hyperglycemia and glycaemic variability, which might in turn promote ketone body production. The addition of SGLT-2 inhibitors further may promote ketogenesis even though there are reports of SGLT-2 inhibitors increase Glucagon-like-peptide-1 (GLP-1) in patients with T1DM. GLP-1 is a suppressor of glucagon secretion. In summary, knowledge about the effects of SGLT-2 inhibition on ketone body production is scarce, especially during exercise in patients with T1DM. The study seeks to illustrate the effect of SGLT-2 inhibition on glycemic variability and ketone body production during and after recreational exercise in patients with T1DM. The results of study 2 will provide the basis for future studies investigating the underlying mechanisms of potentially modified ketone body production during and after exercise under SGLT-2 inhibition.

NCT ID: NCT04048889 Recruiting - Pain, Postoperative Clinical Trials

Addition of Popliteal Plexus Block to Continuous Femoral Nerve Block for Total Knee Arthroplasty

Start date: July 22, 2019
Phase: N/A
Study type: Interventional

The popliteal plexus block has been described as an alternative analgesic postoperative pain treatment for total knee arthroplasty. It consists of injecting local anaeshetics inside the distal end of the adductor canal close to the adductor hiatus, adjacent to the femoral artery, between the medial vastus muscle and the adductor magnus muscle, in order to anesthetize the popliteal plexus. However, the analgesic efficacy has never been demonstrated in a randomized controlled trial. Therefore the objective of this study is to investigate the analgesic benefit of this block combined with a continuous femoral nerve block, on patients scheduled for total knee athroplasty.

NCT ID: NCT04048187 Withdrawn - Hearing Loss Clinical Trials

Quality Control of CE-Certified Phonak Hearing Aids - 2019_23

Start date: August 20, 2019
Phase: N/A
Study type: Interventional

Phonak Hearing Devices pass through different development and study phases. At an early stage, feasibiltiy studies are conducted to investigate new algorithms, features and functions in an isolated manner. If the benefit is proven, their performance is then investigated regarding interpendency between all available algorithms, features and functions running in parallel in a hearing aid (pivotal/pre-validation studies) and, resulting from the pre-validation studies, they get optimized. Prior to product launch, the Phonak Hearing Systems get reviewed by a final quality control in terms of clinical trials. This is a pre-validation study, investigating improved algorithms, features, functions and wearing comfort. This will be a clinical investigation which will be conducted mono centric at Sonova AG Headquarters based in Stäfa (Switzerland).
