Fatigue is a clinical symptom that has been described as the most disturbing by around 50% of patients with PBC. It has an important impact on patients' quality of life and is associated with an increased mortality risk. To treat fatigue in PBC, only medical treatments have been tested with limited efficacy or serious sides' effects. In other diseases, mostly cancer, psychological interventions showed efficacy on fatigue decrease. Most interventions consist in psychoeducation with: education about fatigue, development of self-care or coping techniques, activity management and learning to balance between activities and rest. Hypnosis, which consists in a body work for psycho-therapeutic use (e.g., through imagination), has also shown promising results. Moreover, psychological intervention efficacy seems to be influenced by patients' characteristics, such as personality. Therefore, the first aim of the present single-center randomized controlled phase 2 trial is to assess the efficacy of a psycho educational intervention and a hypnosis intervention on PBC patients' fatigue to demonstrate that both psychoeducational and hypnosis interventions decrease patient fatigue.
This study will explore the impact of lumacaftor/ivacaftor (LUM/IVA) on disease progression in subjects aged 2 through 5 years with cystic fibrosis (CF), homozygous for F508del (F/F).
To investigate the safety and efficacy of PRI-724 against HCV or HBV liver cirrhosis.
This study will evaluate the safety and pharmacokinetics (PK) of lumacaftor (LUM) and ivacaftor (IVA) in participants 1 to less than 2 years of age with cystic fibrosis (CF), homozygous for F508del (F/F).
The effect of portal hypertension on gastrointestinal motility, and how reversal or improvement in portal hypertension may alter gastrointestinal motility, remains unclear and further research is needed. Additionally, patients with cirrhosis have altered gut microflora, particularly rich in lactobacilli, including enterococci and bifidobacteria. Transjugular Intraheptic Portosystemic Shunting (TIPS) is a procedure performed by interventional radiologists, in which a connection is made between the portal and venous circulations, allowing high pressure portal blood to more easily enter the systemic circulation and bypass the liver; thus effectively decreased portal pressure.
This is an observational cohort study building on an existing protocol at our institution recruiting CF patients who are 6-21 years old with one or two copies of the F508del CFTR mutation. That existing protocol seeks to enroll a total of 38 subjects; it includes three to four (three scheduled, with a fourth optional) study visits, with spirometry, LCI, UTE MRI, and 129Xe MRI being performed at each visit. This present study will utilize existing study visits for the NHLBI study, with a sub-set of 20 subjects opting-in to have all of the procedures performed twice, with an intervening ACT, during one of their study visits.
The study population is comprised of adult subjects with cystic fibrosis (CF) who are homozygous for the F508del mutation and are currently receiving background treatment with tezacaftor/ivacaftor for a minimum of 1 month prior to Day 1. The planned sample size is approximately 40 subjects. 20 subjects will be assigned to PTI-428 dose level 1 or placebo and 20 subjects will be assigned to PTI-428 dose level 2 or placebo. At each dose level, subjects will be randomized at a 3:1 randomization ratio. Subjects will receive once daily oral doses of PTI-428 or placebo for 28 days, while the subjects continue to receive background treatment with tezacaftor/ivacaftor per product label. The study drug administration period will be followed by a 14-day safety follow-up period.
Portacaval pressure gradient (PPG) plays an important role in prediction the outcomes of cirrhotic patients undergoing TIPS. An PPG over 20 mmHg indicates a high risk of failure to control bleeding or preventing rebleeding, while patients with PPG <12 mmHg are free from the risk of variceal bleeding. Transjugular intrahepatic portosystemic shunt (TIPS) markedly reduces PPG and is a very effective treatment for portal hypertension. A recent study showed that timing affects measurement of portacaval pressure gradient (PPG) after TIPS placement in patients with portal hypertension. The immediate PPG after TIPS placement cannot predict the long-term prognosis, while PPG measured with the patient on stable clinical conditions correlates with long term PPG and clinical outcomes. However, this finding remain to be validated. Previous studies have demonstrated that the achievement of a hepatic vein pressure gradient <12 mmHg eliminated the risk of recurrent variceal hemorrhage. Therefore, a post- TIPS PPG <12 mmHg was initially proposed as a hemodynamic target of TIPS, independent of the indication. It is important to note that most studies on hemodynamic targets were done before the introduction of covered stents and have not been adequately updated since then.Therefore, whether a post-TIPS PPG target <12 mmHg is the best cutoff for patients receiving a covered stent for the treatment of portal hypertension complications needs confirmation in well-designed studies.This study aims to dynamically monitor the change of PPG after TIPS procedure in patients with portal hypertension, and investigate its prognostic value in predicting patient outcome.
This clinical study is a Phase I, open-label, single-center study designed to evaluate the pharmacokinetics profile of a single oral dose of GLPG3067 in adult male subjects with cystic fibrosis in fed state.
