This study is a multicenter, randomized, double-blinded, placebo-controlled trial to evaluate the safety and efficacy of ExoFlo for the treatment of moderate-to-severe ARDS (Acute Respiratory Distress Syndrome). The purpose of this study is to research and evaluate the safety and efficacy of intravenous (IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles, ExoFlo, as treatment for Moderate-to-Severe ARDS. Bone Marrow Mesenchymal Stem Cell (bmMSC)-Derived Extracellular Vesicles is an investigational drug created from human bone marrow being studied for the treatment of moderate-to-severe ARDS. This is a research study that will involve monitoring oxygen and inflammation levels after taking the investigational product and assessing the safety of the investigational product. The experimental treatment is a biologic product called Bone Marrow Mesenchymal Stem Cell (bmMSC)-Derived Extracellular Vesicles Allograft Product ExoFlo, which is purified from the bone marrow of a healthy well-screened individual. Participants will receive either 15mL of the investigational product with 85 mL of normal saline or 100 mL of normal saline only (placebo). The expected duration of participation in the study is a maximum of 61 days, which includes 1-day screening prior to treatment and 60 days following the first treatment.

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.

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 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.

The Southeastern Consortium for Lung Cancer Health Equity (SC3), led by Dr. Robert A. Winn, assembles an outstanding interdisciplinary team of translational researchers positioned in the heart of the historical and current tobacco-producing region within the southeast. Collectively, SC3's investigative team has unparalleled experience in lung cancer screening, translational research in lung cancer health disparities, community outreach and engagement, and recruiting and retaining racial and ethnic minorities and individuals from other medically underserved groups using evidence-based strategies. As NCI-designated cancer centers, all three centers report high enrollment of underserved minorities onto interventional trials and are committed to reducing the substantial disparities found in lung cancer outcomes in their collective Black/African American and rural communities.

This research is being done to better understand how anti-cancer drugs affect cells within a tumor. Injecting very small amounts (microdoses) of pembrolizumab alone or in combination with MK-0482 or MK-4830 above may help the developer of these drugs to understand more about how these drugs work and what changes they make on the tumor. Subjects in this study will have their tumor injected with anti-cancer drugs using a CIVO device. The CIVO device delivers microdoses of multiple drugs or drug combinations directly into the tumor. Some of the procedures in this study include ultrasound assisted placement for tumor injection, a mucrodose injection of anti-cancer drugs into the tumor, and surgery to remove the tumor. Participation in the study will take 5 visits over a period if 56 days. The screening portion will be 28 days and the treatment portion will be 28 days from the time of the injection to the time of follow-up contact by the study team.
