NCT03208868
Loss of skeletal muscle mass or sarcopenia is the most common and potentially reversible complication in cirrhosis that increases morbidity and mortality before, during and after liver transplantation. No proven treatments exist for the prevention or reversal of sarcopenia in cirrhosis, primarily because the mechanisms responsible for this are unknown. Based on compelling preliminary studies and those of the co investigator, investigators hypothesize that the mechanism of reduced skeletal muscle mass in cirrhosis is due to a myostatin mediated impaired mTOR (mechanistic target of rapamycin) signaling resulting in reduced protein synthesis and increased autophagy. Investigators further postulate that leucine, a direct stimulant of mTOR, will reverse the impaired mTOR phosphorylation in the skeletal muscle of cirrhotics. The consequent increase in protein synthesis reduced autophagy will result in an increase in skeletal muscle mass. Investigators will test these hypotheses by quantifying the response to acute and long term (3 month) administration of leucine enriched essential amino acid (EAA/LEU) compared with an isonitrogenous isocaloric non-essential balanced amino acid mixture (does not stimulate protein synthesis) in cirrhotic patients. Fractional protein synthesis rate (FSR) in skeletal muscle, responses of the molecular regulatory pathways of skeletal muscle protein synthesis, and autophagy flux will be quantified in the acute and long term protocols. Tracer studies using L-\[D5\]-phenylalanine (Phe) as a primed constant infusion (prime 2µmol.kg-1.hr-1; constant 0.05 µmol.kg-1.hr-1) with and L \[ring-D2\] tyrosine, forearm plethysmography, and sequential skeletal muscle biopsies (total of 3 per study subject) will be used to quantify these outcomes. Anthropometric, clinical and body composition measures will be additional outcome measures for the long term intervention. Expression of regulatory signaling proteins, myostatin, IGF-1 (insulin like growth factor) , phospho-Akt, phospho-AMPK (activated protein kinase), phospho-mTOR and phospho-p70s6k will be quantified by Western immunoblots. Autophagy flux will be measured by quantifying expression of the autophagosome proteins.
NCT03464097
This is a study to demonstrate the effect of oral ozanimod as maintenance therapy in participants with moderately to severely active Crohn's Disease.
NCT07060261
This prospective research study aims to see if pre-operative MRI can predict the margin status after transoral robotic surgery (TORS) for human papillomavirus positive (HPV+) tonsillar squamous cell carcinoma (SCC). The pre-operative MRI will have a standard MR neck without and with contrast, with added axial T2 weighted sequence and T2 SPACE sequence through the tonsils. Three neuroradiologists will grade the thickness of the pharyngeal constrictor muscle (the muscle that surrounds the tonsils) on a five-point scale. The study will determine if the pre-operative MRI grading will correlate with positive, insecure (\<1mm), or secure (\>1mm) margin during TORS surgery for your HPV+ tonsillar SCC.
NCT02000089
Johns Hopkins clinical research office quality assurance group will monitor and audit this study at Johns Hopkins. The Sub Investigator at each site will be responsible for internal monitoring at their site.
NCT07214909
To determine the gastric emptying time for clear liquids at different volumes in the adult population, for use in determining anesthesia guidelines.
NCT05186077
The goal of this cross-sectional study is to use diffusion-weighted imaging based tractography (DWT) to assess white matter (WM) pathways in treatment-refractory bipolar disorder (REF-BD) and treatment responsive bipolar disorder (RSP-BD) subjects compared to healthy controls (HCs). This project will include a prospective controlled trial to include 50 subjects with REF-BD, 50 patients RSP-BD and 50 healthy volunteers.
NCT06729606
This study looks at the safety and effectiveness of Aviptadil in treating COVID-19 in people who have been hospitalized with the infection and who have acute respiratory failure. Participants in the study will be treated with Aviptadil plus current standard of care (SOC), or with placebo plus current SOC.
NCT07213622
The use of smart glasses for saphenous nerve adductor canal blocks compared to standard of care.
NCT05421598
This is a parallel, Phase 2, global, multicenter, randomized, double-blind, placebo-controlled, dose-ranging, four-arms study for treatment. The purpose of this study is to assess the efficacy, safety, and tolerability of add-on therapy with amlitelimab in adult participants with moderate-to-severe asthma. Study details include: * The study duration (per participant) will be up to approximately 76 weeks for participants not going into LTS study and will be up to approximately 64 weeks for participants going into LTS study. * The randomized treatment duration will be up to approximately 60 weeks. * The scheduled number of visits will be 13.
NCT06410976
This is a long-term, multicenter, non-interventional study of children ages 2.5 to \<17 years with hypochondroplasia (HCH).
NCT04810078
The purpose of this study is to evaluate the drug levels, efficacy, safety, and tolerability of subcutaneous nivolumab versus intravenous nivolumab in participants with previously treated clear cell renal cell carcinoma that is advanced or has spread. The purpose of this study's substudy is to evaluate drug level biocomparability of subcutaneous nivolumab manufactured using two different manufacturing processes.
NCT05383274
Single-arm, prospective study assessing semen quality after treatment with the Optilume Urethral DCB in men between 22 and 65 years of age.
NCT04931654
This is a Phase I/IIa study designed to evaluate if experimental anti-PD-1 and anti-TIM-3 bispecific antibody, AZD7789 is safe, tolerable and efficacious in participants with advanced solid tumors.
NCT04363801

NCT06747858
ARCT-032-02 is a Phase 2, open-label, multicenter, multiple-ascending dose study of ARCT-032 in adults with CF who are not eligible for CFTR modulator therapy or are not taking CFTR modulators due to drug intolerance, poor response, or lack of access to modulators.
NCT01908777
The purpose of this study is to test the benefit of a chemotherapy drug called romidepsin in patients with T Cell Non-Hodgkin Lymphoma (T NHL) who have undergone autologous transplantation.
NCT02290951
This study has two parts with distinct study objectives and study design. In part A, odronextamab is studied as an intravenous (IV) administration with a dose escalation and a dose expansion phase for B-NHL and CLL. The dose escalation phase for B-NHL and the CLL study are closed at the time of protocol amendment 17. In part B, odronextamab is studied as a subcutaneous (SC) administration with a dose finding and a dose expansion phase for B-NHL.

NCT06939348
The overall aim of this study is to develop an intervention that can help recovery in patients surviving severe brain injury but failing to fully recover. In particular, this multicenter project aims to (1) establish short-term efficacy of tFUS as a therapeutic to promote recovery in patients with prolonged DoC as compared to sham treatment, (2) establish dose-related safety and efficacy of tFUS as a therapeutic intervention in prolonged DoC patients and (3) explore preliminary predictors and biomarkers of susceptibility and response to thalamic sonication.
