      Smartphone App for Alcoholism in Homeless Adults

      Oklahoma City, Oklahoma
      Approximately 1 out of every 3 adults experiencing homelessness has a current alcohol use disorder (AUD). Alcohol use plays a central role in increased morbidity and mortality in this population, with some studies suggesting it plays a direct role in as many as 17% of deaths. Alcohol is also a leading cause of homelessness and contributes to its chronicity by inhibiting progress toward obtaining employment and a stable living environment. Shelter-based treatments are common, but compliance is often poor. There are many documented challenges to effectively implementing traditional evidence-based interventions in shelter settings. In the current project, we will conduct a randomized controlled trial. Adults currently experiencing homelessness who report hazardous alcohol use (N = 600) will be recruited from five shelters across the Dallas, TX and Oklahoma City, OK metropolitan areas. Individuals will attend screening and training visits, then complete one week of self-monitoring (via smartphone app) before being randomized to receive either standard shelter-based treatment (Usual Care; UC), or the Smart-T Alcohol intervention + UC. The Smart-T Alcohol intervention offers on-demand content and automated contextually tailored messages to reduce alcohol consumption. The intervention period will span eight-weeks (i.e., weeks 2-9), with follow-up assessments occurring at weeks 9, 13, and 26. All participants will complete brief daily smartphone-based surveys for 13 weeks. Aims of the project will be to assess the effects of the Smart-T Alcohol intervention on alcohol use and alcohol-related problems (Aim 1), intervention effects on key drinking risk indicators and their mediation of use outcomes (Aim 2), and identify specific subpopulations (e.g., women, racial/ethnic minorities, younger adults; Exploratory Aim 3) for which the intervention is most effective. Findings will provide a rigorous evaluation of the efficacy of the Smart-T Alcohol intervention and guide future smartphone-based interventions for this population.

      Educational Website for Colorectal Cancer

      Oklahoma City, Oklahoma
      This phase III trial evaluates whether a web-based intervention called Current Together after Cancer (CTAC) works to increase the number of patients with surgically removed (resected) colorectal cancer who receive surveillance care that aligns with current guidelines (guideline-concordant). Surveillance care after resection of colorectal cancer is critical to detect potentially curable return of disease (recurrence), yet up to 60% of colorectal cancer survivors fail to receive surveillance. This may be due to a lack of knowledge about the purpose of surveillance care and the risks of cancer recurrence, or a lack of confidence for managing surveillance care. The CTAC intervention is an online education intervention designed to improve patients' knowledge about surveillance and their self-efficacy for managing surveillance, and to promote effective communication with supporters and supporter engagement in patients' surveillance in a way that is aligned with each patient's preferences. By increasing a patient's knowledge, self-efficacy, and satisfaction with their supporter's engagement in their care, the CTAC intervention may increase the number of patients who receive guideline-concordant surveillance care after resection of colorectal cancer.

      Chemotherapy + Immunotherapy for Acute Lymphoblastic Leukemia

      Oklahoma City, Oklahoma
      This randomized phase III trial studies combination chemotherapy with blinatumomab to see how well it works compared to induction chemotherapy alone in treating patients with newly diagnosed breakpoint cluster region (BCR)-c-abl oncogene 1, non-receptor tyrosine kinase (ABL)-negative B lineage acute lymphoblastic leukemia. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether combination chemotherapy is more effective with or without blinatumomab in treating newly diagnosed acute lymphoblastic leukemia.

      Trophic Feeding for Sepsis Prevention

      Oklahoma City, Oklahoma
      Study Hypothesis/Question In infants born very preterm, advancing enteral feeds after 24 hours from birth (limited trophic feeds) versus after 72 hours (extended trophic feeds) reduces the risk of all-cause late onset sepsis (LOS) without increasing the risk of other adverse outcomes. Study Design Type This is a multi-center, open-label, parallel-group, individual randomized controlled trial comparing two different trophic feeding regimens in preterm infants born between 25w0d and 31w6d. These infants will be randomly assigned to either the intervention group, receiving limited trophic feeding (20 to 25 mL/kg/day for one day) or the control group, receiving extended trophic feeding (20 to 25 mL/kg/day for three days) prior to advancing enteral feeds until full feeding volume (140 mL/kg/day) is achieved. Eligibility Criteria Preterm infants with gestational ages between 25 0/7 and 31 6/7 weeks and a birthweight of \<1500 grams who are admitted to six participating neonatal units will be eligible for inclusion. Infants with \<5th percentile for weight at birth, vasopressor use within first 24 hours of life major congenital/genetic anomalies affecting enteral feeding, growth, or mortality, and those with a terminal illness in which decisions to withhold or limit support have been made will be excluded. Infants of parents or legal guardians who are unable to provide consent within 36 hours of birth will also be excluded. Study Intervention/Methods Written parental informed consent will be obtained prenatally or within the first 36 hours of birth. Infants will be randomized to receive limited trophic feeds of 24 to 36 hours or extended trophic feeds for 72 hours prior to the advancement of enteral feeds. Infants will be fed parent's own milk (POM) with donor human milk as the alternative if POM is unavailable. Primary Outcome Late-onset sepsis, defined as positive blood, urine, and/or cerebrospinal fluid (CSF) cultures in the presence of compatible clinical signs of sepsis, occurring after postnatal day 3 and before hospital discharge, and treated with antibiotics for 5 days or more. Secondary Outcome(s) The trial will assess various secondary outcomes including length of hospital stay, all-cause in-hospital mortality, duration of IV fluids and central line utilization, necrotizing enterocolitis (Bell's stage IIa or higher), severe intraventricular hemorrhage (grade III or IV either unilaterally or bilaterally), bronchopulmonary dysplasia (oxygen requirement or positive pressure ventilation at 36 weeks corrected gestational age), or retinopathy of prematurity requiring intervention. Additionally, growth metrics throughout hospitalization will be evaluated using change in weight, length, and head circumference z-scores from birth to 36 weeks' corrected gestational age between infants in the limited and extended trophic feeding groups.

      Intranasal Medications for Anxiety During Pediatric Procedures

      Oklahoma City, Oklahoma
      Pain in young children has been universally under-recognized due to their inability to describe or localize pain. Improvements in pharmacological interventions are necessary to optimize patient and family experience and allow for successful and efficient procedure completion. This is the first study that will compare three intranasal medications (Intranasal Midazolam, Dexmedetomidine, and Ketamine) to evaluate the length of stay after medication administration along with patient and provider satisfaction. The objective of this study is to demonstrate superior intranasal anxiolysis for pediatric laceration repairs with the shortest emergency department stay and highest patient and provider satisfaction. Based on previous studies and medication pharmacokinetics, we hypothesize that Intranasal Ketamine will have the shortest Emergency Department (ED) stay followed by Midazolam and then Dexmedetomidine with the longest stay; however, Dexmedetomidine will have the highest patient and provider satisfaction followed by Ketamine and then Midazolam.

      Cannabis Use on Sedation for Dental Procedures

      Oklahoma City, Oklahoma
      The use of Cannabis is increasing in the population, and the effects that this might have on different medical procedures are poorly understood. Particularly when submitted to deep sedation or general anesthesia, there is no consensus on best drugs or doses to deliver. The purpose of this clinical trial is to clarify the influence of chronic cannabis use during office based general anesthesia for extraction of teeth. The procedures will be performed in the Oral and Maxillofacial Surgery Clinic at the College of Dentistry.

      Fluconazole for Vascular Response in Healthy Subjects

      Norman, Oklahoma
      Most cardiometabolic diseases are characterized by increased muscle sympathetic nerve activity (MSNA) during rest and exercise which contributes to poor health outcomes. In healthy humans during muscle contraction, there is a blunting of skeletal muscle vascular responsiveness to increases in MSNA. However, the exact mechanisms involved are unknown although, best evidence suggests that the mechanism is endothelium derived, but nitric oxide (NO) and prostaglandin (PG) independent. Endothelium-derived hyperpolarizing factor (EDHF) is a NO and PG independent vasodilator in both cerebral and skeletal muscle circulations, however, it is unknown if EDHF contributes to vascular responsiveness during elevated MSNA. The application of lower body negative pressure (LBNP) is a safe and non-invasive manipulation that can be used to increase MSNA causing vasoconstriction in humans. Therefore, the purpose of this experiment is to determine if acute inhibition of EDHF alters central and peripheral vascular responses to LBNP at rest and during dynamic exercise. Thereby, providing evidence by which EDHF contributes to vascular control in healthy humans and identify it's potential as a therapeutic target for cardiometabolic diseases that are characterized by elevated MSNA

      LPS for Major Depressive Disorder

      Tulsa, Oklahoma
      This is a parallel group, double-blinded, placebo-controlled study. Participants with MDD (n=90) and HC (n=90) will be randomly assigned (2:1) to receive either lipopolysaccharide (LPS) (0.8ng/kg of body weight) or placebo (same volume of 0.9% saline) administered as an intravenous bolus. This will yield the following groups: MDD-LPS (n=60), MDD-Placebo (n=30), HC-LPS (n=60), HC-placebo (n=30). There are three main aims: to identify immune pathways and neural circuits that respond differently to LPS in MDD vs. HC subjects; (2) to test whether the strength of inflammatory changes induced by LPS is associated with degree of change in anhedonic symptoms and neural circuits in the MDD group, and (3) to identify a biotype of MDD that shows a differential immunological and neurophysiological response to LPS. The main outcome variables are symptoms of anhedonia measured with the Snaith-Hamilton Pleasure Scale (SHAPS), cytokines (Il-6, IL-8, IL-10, and TNF), and BOLD signal change in the neural circuitry mediating interoceptive processing, i.e. the insula and cingulate cortex. The exploratory aim is to determine whether the acute inflammatory response to LPS can predict the clinical course of depression over a period of six months. The main outcome of this component of the study is self-reported depressive symptoms assessed with the QIDS-SR.

      Varenicline + Nicotine Lozenges for Smoking Cessation

      Oklahoma City, Oklahoma
      Although the prevalence of smoking has declined among U.S. adults, smoking remains the leading preventable cause of cancer incidence and mortality. Quitting smoking increases life expectancy, and quitting at an earlier age is associated with more years of life gained. Effective pharmacotherapies to aid cessation are available, and the combination of behavioral support with pharmacotherapy optimizes cessation outcomes. Varenicline is an effective, first-line smoking cessation treatment, and recent research has investigated combination pharmacotherapy to improve the modest quit rates observed with monotherapy. The findings of two meta-analyses have indicated that varenicline combined with the nicotine patch was more effective than varenicline alone for smoking cessation However, no published studies to date have evaluated the combined impact of varenicline and oral nicotine replacement therapy (NRT) on smoking cessation in a randomized trial. Oral NRT, such as nicotine lozenges, can provide acute relief from cravings/withdrawal, and offers individuals the flexibility to deliver nicotine quickly, in contrast with the continuous, passive, and slow-acting delivery of the nicotine patch. Nevertheless, in clinical trials of other combination pharmacotherapies, participants' adherence to of oral NRT has been suboptimal, making it difficult to determine whether there is an added benefit. Given the near-ubiquity of smartphone ownership (85% of U.S. adults), it is plausible that smartphone-based medication adherence interventions could have a positive influence on pharmacotherapy adherence and smoking cessation. This investigative team has demonstrated the feasibility and potential efficacy of using combination varenicline plus oral NRT treatment to promote smoking cessation in a pilot factorial randomized trial. Likewise, pilot findings showed that medication adherence and smoking cessation rates were higher among those who received smartphone-based medication reminders than those who did not. The proposed study will enroll 496 adults who smoke cigarettes daily. The study will employ a 2x2 factorial design in which participants will be randomized to one of four combinations of two treatment factors: 1) pharmacological treatment (varenicline + nicotine lozenges vs. varenicline alone) and 2) smartphone medication adherence intervention (smartphone-based smoking cessation app with vs. without adherence components). The primary study outcomes will be biochemically-confirmed 7-day point prevalence abstinence at 26 weeks after a scheduled quit date, and medication adherence over the 13-week treatment period. Smartphone-based daily diaries will be employed to assess daily smoking and medication adherence. Notably, the proposed study will employ entirely remote assessment and treatment delivery strategies. Exploratory analyses will evaluate the potential interaction between medication type and the smartphone adherence intervention, and compare the influences of pharmacological treatment type and the medication adherence intervention on weekly physical symptoms (e.g., withdrawal, medication side effects). The overarching goal of the proposed research is to improve smoking cessation treatment and decrease cancer risk.

      Neuromodulation for Pulmonary Arterial Hypertension

      Oklahoma City, Oklahoma
      Patients with Group 1 pulmonary hypertension will be enrolled in this study. Investigators will test the hypothesis of low-level tragal stimulation in patients with pulmonary hypertension. The study will be conducted over 4 weeks and patients will undergo low-level tragus stimulation for 1 hour every day for 4 weeks. At baseline the following tests will be conducted-6-minute walk distance, vascular function testing using noninvasive device and blood samples will be collected. Patient will also undergo a limited echocardiography to assess right ventricular function. After 4 weeks of stimulation patients will come back to undergo these tests again. Investigators hypothesized that low-level tragus stimulation (neuromodulation) will lead to improvement in vascular function, 6-minute walk distance and blood based biomarkers in patients with pulmonary hypertension.

      Frequently Asked Questions

      How much do clinical trials in Oklahoma pay?

      Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

      How do clinical trials in Oklahoma work?

      After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across trials in Oklahoma 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length in Oklahoma is 12 months.

      How do I participate in a study as a "healthy volunteer"?

      Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility in Oklahoma several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

      What does the "phase" of a clinical trial mean?

      The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

      Do I need to be insured to participate in a medical study in Oklahoma?

      Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

      What are the newest clinical trials in Oklahoma?

      Most recently, we added Varenicline + Nicotine Lozenges for Smoking Cessation, Warmed HSG for Infertility and Selpercatinib for Cachexia-Anorexia Syndrome to the Power online platform.
