5-aminosalicylic acid (5-ASA) medications are first line treatment for mild to moderate Ulcerative Colitis (UC), comprise 81% of all UC prescriptions, and have a market share of 1.5 billion. However, despite 5-ASA frequency and optimization, 35% of patients fail induction therapy and 52% of patients fail to maintain remission at 12 months, requiring step up therapy to immunomodulators or biologics which have increased side effects and cost. This highlights a key challenge in UC which is to address the large inter- and intrapatient variabilities in both disease progression and variability in response to treatment. Chronotherapy is the timing of medical interventions according to the host circadian rhythms in order to optimize drug response and minimize toxicity, and is one explanation for the large variability in response to medications. The long-term objective of our research is to establish the hypothesis that is that appropriate time of day of administration of oral, once daily 5-ASA therapy in alignment with the host circadian rhythms will improve subclinical inflammation and microbial structure/function and increase mucosal 5-ASA levels. To test this hypothesis, In
response to the small R01 for pilot and feasibility clinical trials (PAS-20-160) and to test our hypothesis, we propose to conduct a six month, single center, randomized crossover pilot trial involving 60 subjects with inactive UC [Mayo score ≤2, endoscopic score 0-1] but subclinical inflammation [stool calprotectin > 50 mcg/g] on a stable dose of once daily 5-ASA medication. All subjects will be randomized to once daily 5-ASA medications two different times of the day: either between 06:00 – 10:00 h or 18:00 – 22:00 h. Three disease assessments will performed at: 1) enrollment just before randomization; 2) month 3, at the completion of first arm (condition 1), and 3) month 6, after completion of the second arm (condition 2). We will assess time impact of our chronotherapy protocol on: 1) subclinical inflammation (Aim 1): a) stool calprotectin; b) intestinal barrier integrity; and c) endoscopic/histology scores; 2) Microbiota: mucosal and stool microbiota structure and function (Aim 2); and 3) 5-ASA metabolism: a) increase mucosal levels of 5-ASA and b) mucosal NAT activity (Aim 3). In addition, optimal 5-ASA treatment (i.e., Aims 1-3) will depend upon host chronotype which will be monitored by validated questionnaires, rest-wake actigraphy, and urinary melatonin. The results of this innovative proposal will establish a key role for chronotherapy in the treatment of UC and provide pilot data for the future larger multicenter clinical trials. Chronotherapy will allow for a personalized medicine approach that incorporates circadian biology to improve efficacy and minimize intolerance in treatment of UC.

The purpose of this study is to assess the feasibility and safety of modified surgical eyeglasses to view bevonescein intraoperatively and the safety of bevonescein as it shows nerve tissue in the body. Bevonescein is an investigational drug being developed to help doctors identify nerves within the body during surgery.
The drug is administered through a vein in the arm and into the blood stream.t Bevonescein then travels through the blood where it makes nerve tissue fluorescent so that it can then be detected by the modified surgical eyeglasses used in this study by a surgeon. This may help the surgeon (study doctor) to tell the difference between nerve tissue and other tissue during surgery. Bevonescein and the modified surgical eyeglasses that your surgeon will wear (ReVealTM 475) are considered investigational because they are not approved by the Food and Drug Administration (FDA) to help with the visualization of nerves during surgery Alternatives to this study can include to undergo surgery without the study drug.

The duration of this study is about 2 months. The procedures of this study include administration of the study drug once (500 mg), collection of blood and urine samples, and ECGs. Surgery will happened as planned by the study doctor but as part of the research, the surgeon will ear modified surgical eyeglasses to view nerves and may take pictures or video clips. The glasses are FDA cleared but the modified filter and its use in combination with bevonescein is considered experimental.

The most commonly expected risks of fluorescein are nausea, vomiting, and stomach discomfort. Because bevonescein is cleared through the urine, there may be a potential risk to the kidneys and renal (kidney) system. The most serious risks of fluorescein may include severe local tissue damage, anaphylaxis, convulsions, cardiac arrest, and death.

This will be a 26-week, prospective, multicenter, randomized, double-blind, placebo-controlled safety and efficacy study of udenafil 87.5 mg tablets versus placebo (both taken twice daily in adolescent subjects who have had the Fontan procedure. The primary efficacy endpoint will be change from baseline at 26 weeks in peak minute oxygen consumption [VO2] (mL/kg/min).

This study is part of what is called a platform study. This platform study, called the "PRACTICAL" study is designed so that various interventions can be evaluated at the same time against standard therapy. This allows researchers to compare these newer interventions to each other as well as to the established usual practice and helps them explore different ways to potentially improve the management of lung injury. Within the platform study there are various different sub-studies that have their own interventions and procedures. This domain sub-study is the "Mechanical Ventilation Study" and it is a multi-centre, randomized, open-label trial that will evaluate multiple ventilation strategies in comparison to conventional lung-protective ventilation in patients with acute hypoxemic respiratory failure (AHRF). This domain will enroll perpetually, as interventions are added, continued, or discontinued. Researchers for this study are looking for different types of ventilation strategies (ways that the ventilators control settings can be adjusted) that may be the most helpful for people in their recovery, while also reducing lung damage caused by the ventilator.

The purpose of this study is to identify whether investigational blood and tissue testing can detect cancer cells in the blood stream can tell if subjects are responding to their individual treatment plans.

Participation will last as long as the subject's individual treatment plan and will consist of collecting tissue biopsies (10 slides), which will be taken during the subject's standard of care procedure, as well as blood draws (between 1 and 2 tablespoons), which will be taken during each of the subject's standard of care clinic appointments throughout their care journey.

The goal of this project is to better understand the relationship between tobacco/nicotine and cannabis using behavioral economics during a tobacco/nicotine quit attempt. All participants will receive tobacco/nicotine cessation treatment (smoking and/or vaping treatment) for 12 weeks. To qualify, participants must be between the ages of 18-25 and use tobacco products (smoke cigarettes and/or vape nicotine) and use cannabis (in any form). Participants do not need to be interested in quitting cannabis/marijuana to qualify. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed.

The study is for patients who have been diagnosed with non-squamous non-small cell lung cancer (NSCLC). The investigational drug in this study is ivonescimab (AK112). The study drug is an antibody, it blocks two proteins in the body that help cancer cells live, grow and spread. The study drug will be given in addition to pemetrexed and carboplatin. There are two groups that a participant may be assigned to, which group a subject is assigned on will be determined by type of cancer treatments that they have previously received. Treatment Group A will receive the study drug along with pemetrexed and carboplatin. Treatment Group B will receive placebo along with pemetrexed and carboplatin. The drugs will be given via an infusion. There is a 50% chance of being assigned to either group. Participation in the study will last about 36 months. The study consist of a screening visit, treatment visits, and a safety follow up visit.

The purpose of this research is to determine the safety and tolerability, the best dose for future development, as well as antitumor activity of a new antibody drug conjugate (ADC) called MYTX-011. MYTX-011 is a new drug, being studied in humans for the first time for treatment of advanced non-small cell lung cancer. The study team is investigating this drug to help treat lung cancers that are resistant to standard medications. This drug targets a protein called cMET on the cancer cell. MYTX-011 will attach to the cMET and release chemotherapy into the cancer cell.

Social anxiety, which broadly consists of fears related to being negatively evaluated and avoidance of social situations, is highly prevalent among Veterans. Social anxiety is associated with significant deficits in social and occupational functioning. This study aims to evaluate a brief text-based intervention for decreasing social anxiety related safety behaviors among Veterans attempting to re-integrate into the workforce. Findings from this study will examine the efficacy of the text based intervention with aims at improving functional outcomes and quality of life among Veterans. Additional data from participating Veterans will provide valuable feedback on the intervention and assist in future refinement.
