NCT ID: NCT04545983 Completed - Spinal Stenosis Clinical Trials

Long-term Follow-up Motion Analysis of ACD Versus ACDA

Start date: February 12, 2022
Phase: N/A
Study type: Interventional

Rationale: Cervical degenerative disc disease (CDDD) is a common cause of cervical radiculopathy, myelopathy or myeloradiculopathy. Surgical treatment is indicated when conservative therapies do not provide sufficient relief or when neurological complaints are progressive. The main surgical techniques are anterior cervical discectomy with (ACDF) or without fusion (ACD), whereas both techniques result in high fusion rates. Short term outcomes of surgery show good clinical results. Long term follow-up shows a drop-in satisfaction rates, often due to the occurrence of new complaints. Pathology is often located at levels adjacent to the previously operated segment, known as adjacent segment disease (ASDis). This is thought to be the results of loss of motion at the previously operated and fused segment. Anterior cervical discectomy with arthroplasty (ACDA) is developed in an effort to reduce the incidence of ASDis by preserving physiological motion in the operated segment. Objective: To investigate physiological motion of the cervical spine the investigators will analyze motion patterns at the long-term in patients who underwent surgical treatment for CDDD, either ACD or ACDA. Study design: Fundamental research. This is a prospective study that includes a cohort of patients previously operated in the setting of a randomized controlled trial. Study population: Adult patients with an indication of surgical treatment for cervical radiculopathy as a consequence of CDDD were enrolled in an RCT between 2007 and 2014 and assigned to undergo ACD or ACDA. Flexion and extension cinematographic recordings of the cervical spine were performed, with the last one at one-year follow-up. The majority of patients in the ACDA group (80%) showed a normal sequence of segmental contribution, which was not the case in the ACD group. This cohort will now be asked to participate in the long-term follow-up study assessing the motion patterns 6-13 years after ACD or ACDA surgery. Intervention: One flexion and extension cinematographic recording of the cervical spine and will be made. Main study parameters/endpoints: The sequence of segmental contributions in sagittal rotation during flexion and extension of the cervical spine will be assessed in the long-term follow-up of surgical treatment. Secondary outcomes will be to assess the amount of degeneration based on the Kellgren Score (KS) and the segmental range of motion (sROM). Long term clinical outcomes will be assessed according to VAS, NDI, SF-36 and Odom's criteria. Patients will be asked whether they have new neurological symptoms and whether they have had a re-operation. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participants receive cinematographic recordings once. The amount of radiation is a negligible risk. There will be no health benefits. There will be no follow-up.

NCT ID: NCT04544956 Completed - Hepatitis B Clinical Trials

A Mechanistic Study of GSK3228836 With Fine Needle Aspiration (FNA) in Participants With Chronic Hepatitis B

B-Fine
Start date: October 6, 2020
Phase: Phase 2
Study type: Interventional

Hepatitis B virus (HBV) infection, especially chronic, is a significant worldwide medical problem. This is an exploratory study of the therapeutic mechanism of GSK3228836 in participants with chronic hepatitis B (CHB) on stable nucleos(t)ide therapy (which is the first line therapy for CHB). This study is a Phase IIa, multi-center open label exploratory study of the therapeutic mechanism of GSK3228836 in participants with hepatitis B virus e-antigen (HBeAg)-negative CHB on stable nucleos(t)ide therapy using repeat fine needle aspirations of the liver for intrahepatic immunophenotyping. It will investigate the virologic and immunologic correlates of hepatitis B virus surface antigen (HBsAg) loss observed in participants when treated for 12 weeks with 300 milligrams (mg) GSK3228836. Repeat fine needle aspirates of the liver will be performed to enable analysis of liver-resident immune cells to investigate any immunomodulatory properties of GSK3228836 and to study the biology of underlying treatment-associated liver flares. The study will consist of a screening, treatment, and post-treatment follow-up phase. Approximately 20 participants will be enrolled in the study.

Start date: May 10, 2021
Phase: Phase 3
Study type: Interventional

160 subjects with autoimmune pulmonary alveolar proteinosis (aPAP) will be randomized to receive once daily treatment with inhaled molgramostim or placebo for 48 weeks.

NCT ID: NCT04543591 Recruiting - Clinical trials for Thrombotic Microangiopathy

Ravulizumab in Thrombotic Microangiopathy After Hematopoietic Stem Cell Transplant

Start date: December 10, 2020
Phase: Phase 3
Study type: Interventional

This study will evaluate the efficacy, safety, pharmacokinetics, and pharmacodynamics of ravulizumab in adult and adolescent participants with hematopoietic stem cell transplant-associated thrombotic microangiopathy (HSCT-TMA). In Stage 1, an open-label, single-arm period, the dosing regimen will be confirmed. In Stage 2, participants will be randomized to receive either blinded ravulizumab plus best supportive care or matching placebo plus best supportive care. The treatment period is 26 weeks (open-label for Stage 1, and randomized, double-blind, and placebo-controlled for Stage 2) followed by a 26-week follow-up period.

NCT ID: NCT04543409 Terminated - Clinical trials for Eosinophilic Esophagitis

A Study of Benralizumab in Patients With Eosinophilic Esophagitis

MESSINA
Start date: September 22, 2020
Phase: Phase 3
Study type: Interventional

The aim of this Phase 3 study is to investigate the use of benralizumab as a treatment for patients with EoE. The effect of doses of benralizumab on EoE histologic signs and symptoms will be assessed over a 52-week treatment period (including a 24-week double-blind placebo-controlled treatment period and a 28-week open-label treatment period). It is proposed that benralizumab will deplete eosinophils from GI tissue(s), improve the symptoms of dysphagia, and improve endoscopy scores as well as other markers of disease activity. Upon completion of the initial 52-week treatment period, patients will be offered an additional Open Label Extension period of at least 1 year, with benralizumab treatment and ongoing study assessments.
