234 Clinical Trials for Various Conditions
The goal of this randomized cross-over mechanistic trial is to compare pre- and post-level cortisol and oxytocin changes in patients with chronic spine pain who receive either a hand's on (massage) or a hand's off (talk-based) approach. The study plans to address two primary aims. Specific Aim One: Directly compare pre- and post-session oxytocin and cortisol levels across two sessions of massage and talk-based therapy. Hypothesis 1: It is expected that in both treatments, oxytocin will increase and cortisol will decrease, demonstrating no significant between-group differences in hormone levels. Specific Aim Two: The study plans to compare pre- and post-session oxytocin and cortisol change scores a therapeutic alliance (TA) scale change scores and PROMIS patient-reported outcomes associated with pain, depression, and disability. Hypothesis 2a: It is projected that there will be moderate +/- relationships (R\>.4) between the therapeutic alliance change score and oxytocin and cortisol levels, suggesting that the hormones moderately reflect the construct associated with TA. Hypothesis 2b: It is expected that there will be weak (R\>.1) +/-relationships between hormone measures and PROMIS pain/disability/depression measures, which reflects similar findings to preliminary work. Participants will participant in a massage based treatment and a talk-based treatment approach. Participants will also complete patient report outcomes and will receive a total of four salivary swabs.
The goal of this experiment is to further determine if self-dehumanization is a novel risk factor for suicide. This study will reduce self-dehumanization using a novel re-humanization condition and compare this group to a control group to analyze the pathway between higher perceptions of self-dehumanization, suicidal ideation, and changes in oxytocin concentrations. It is hypothesized that participants randomly assigned to the re-humanized condition will exhibit decreases in suicidal ideation and increases in oxytocin concentrations as compared to the control condition, which will not display significant changes. Further, we will explore if the magnitude of the oxytocin response will partially mediate the change in suicidal ideation.
The goal of this experiment is to further determine if self-dehumanization is a novel risk factor for suicide. This study will induce self-dehumanization using a novel experimental self-dehumanized future condition (i.e., a futuristic paradigm that likens the individual to a machine) and compare this group to a control group to analyze the pathway between higher perceptions of self-dehumanization, suicidal ideation, and changes in oxytocin concentrations. It is hypothesized that participants randomly assigned to the self-dehumanized mechanistic future condition will exhibit temporary increases in suicidal ideation (which will be thoroughly assessed, intervened upon following the induction) and decreases in oxytocin concentrations as compared to the control condition, which will not display significant changes. Further, we will explore if the magnitude of the oxytocin response will partially mediate the change in suicidal ideation.
The overall aim of this study is to determine the efficacy and safety of intranasal oxytocin (OXT) to improve the quality of life and reduce chronic stress levels in the caregivers to the persons with dementia. Randomized, double-blind, placebo-controlled clinical trial of intranasal oxytocin (12 or 24 IU) will be conducted by daily administration (once a day) for 21 days (3 weeks).
Leveraging veterans' intimate relationships during treatment for posttraumatic stress disorder (PTSD) has the potential to concurrently improve PTSD symptoms and relationship quality. Brief Cognitive-Behavioral Conjoint Therapy (bCBCT) is a manualized treatment designed to simultaneously improve PTSD and relationship functioning for couples in which one partner has PTSD. Although efficacious in improving PTSD, the effects of CBCT on relationship satisfaction are small, especially among Veterans. Pharmacological augmentation of bCBCT with intranasal oxytocin, a neurohormone that influences mechanisms of trauma recovery and social behavior, may help improve the efficacy of bCBCT. The purpose of this randomized placebo-controlled trial is to compare the clinical and functional outcomes of bCBCT augmented with intranasal oxytocin (bCBCT + OT) versus bCBCT plus placebo (bCBCT + PL). The investigators will also explore potential mechanisms of action: communication, empathy, and trust.
We aim to assess the baseline oxytocin levels in individuals with borderline personality disorder and correlate those levels with social behavior, and compare the results with controls. Primary Hypothesis (H1): There is a significant difference in trust-related behavior as measured by oxytocin (OXT) levels between borderline personality disorder (BPD) patients and healthy controls. Secondary Hypotheses: H2: The trust-related behavior in BPD patients is significantly influenced by their level of emotional sensitivity. Specifically, higher emotional sensitivity in BPD patients is associated with lower trust-related behavior and vice-versa. H3: There is a significant correlation between trust-related behavior and childhood trauma in BPD patients. BPD patients with higher levels of reported childhood trauma will exhibit lower trust-related behavior compared to those with lower levels of trauma. H4: Trust-related behavior in BPD patients varies depending on their attachment styles. Specifically, BPD patients with insecure attachment styles will exhibit lower trust-related behavior compared to those with secure attachment styles. H5: There is a significant correlation between trust-related behavior and BPD severity. Patients with more severe BPD symptoms will exhibit lower trust-related behavior compared to those with less severe symptoms. H6: The levels of OXT in BPD patients will significantly correlate with their reported levels of emotional sensitivity, childhood trauma, attachment styles, and BPD severity. These hypotheses aim to address the complexities surrounding the modulation of trust-related behavior by oxytocin in BPD patients, taking into account various factors like emotional sensitivity, childhood adversity, attachment styles, and BPD severity. By testing these hypotheses, the study aims to provide a comprehensive understanding of the interplay between these factors in influencing trust-related behavior in BPD patients.
The goal of this clinical trial is to learn about oxytocin ( a naturally occurring hormone made in the brain that transmits messages) and the effects it may have on thermal heat pain after intravenous administration. The main question it aims to define is the time course of change in pain score after a 5 minute heating of the skin administered at intervals during and following infusion of intravenous oxytocin in order to create a Pharmacokinetic and a Pharmacodynamic model for oxytocin-induced analgesia. Participants will be asked to rate thermal heat temperatures before, during and after the intravenous infusion of oxytocin.
The goal of this clinical trial is to compare oxytocin infusion rates for induction and augmentation of labor in nulliparous women. The main question\[s\] it aims to answer are: * Does a high dose oxytocin infusion protocol affect length of induction to delivery interval? * Does a high dose oxytocin infusion protocol affect mode of delivery? * Does a high dose oxytocin infusion protocol affect maternal and neonatal outcomes? Participants will be randomized to either low- or high-dose oxytocin groups: * The low dose group will receive an infusion to start at 2 milli-units/min and will be increased by 2 milli-units/min every 20 minutes. The maximum rate of infusion is 40 milli-units/min. * The high dose group will receive an infusion to start at 6 milli-units/min and will be increased by 6 milli-units/min every 20 minutes. Maximum rate of infusion is 40 milli-units/min.
This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin on bone health in children with autism spectrum disorder, ages 6-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (30 IU, 2 times daily) for 12 months in the double-blind phase, followed by a 6-month open label phase during which all study subjects will receive intranasal oxytocin (30 IU, 2 times daily). Study visits include screening to determine eligibility, followed by study visits at baseline, week 2, and months 6, 12, 18 and phone calls every two weeks for the first two months and monthly thereafter for the duration of the study. Study assessments include history and physical examinations, anthropometric measurements, electrocardiogram (EKG), adverse event monitoring, laboratory tests for chemistries, hormones and biomarkers for bone metabolism, questionnaires regarding diet and exercise, and imaging to assess body composition, bone density and structure.
This study evaluates the impact of intranasal oxytocin vs placebo in patients with obesity and binge eating disorder with obesity. We hypothesize that 8 weeks of intranasal oxytocin vs placebo will improve clinical outcomes \[weight loss, reduction in bingeing frequency\], and have a satisfactory safety and tolerability profile. We will also explore the predictive value of changes in homeostatic appetite, reward sensitivity, and impulse control, the identified underlying mediators, as assessed 4 weeks into the intervention, for treatment success after 8 weeks of the intervention
Oxytocin is the first-line drug to promote contraction of the uterus and prevent atony immediately after delivery. Nonetheless, unpredictable uterine atony refractory to oxytocin affects roughly 250,000 parturients annually in the U.S. and rates are increasing. This two-part study will measure the action of oxytocin at cesarean delivery. The first part will measure the pharmacokinetics of a single intravenous (IV) dose of deuterium-labeled oxytocin. The second part will measure the pharmacodynamics of all plasma oxytocin to see how concentrations correspond to the contractile effect on the uterus. After delivery of the fetus, study subjects will receive a bolus of IV deuterated oxytocin followed by an unlabeled oxytocin infusion. Venous blood samples drawn at multiple time points (within 1 hour after delivery) will be analyzed for plasma concentrations of labeled and unlabeled (endogenous + exogenous infused) oxytocin over time. Plasma concentrations will be compared with 0-10 uterine tone scores measuring uterine contraction strength, to describe the concentration-effect relationship. The goal of this study is to define both the pharmacokinetics and pharmacodynamics of oxytocin in parturients to help identify the cause(s) of failed first-line oxytocin therapy.
Pregnant patients with obesity are more likely to undergo induction of labor and have a higher risk of failed induction compared to patients with normal weight. The association between maternal obesity and labor dysfunction leading to cesarean delivery is poorly understood. Oxytocin is the mostly common medication used in induction of labor, yet optimal dosing of this medication is unknown. Studies have suggested that patients with obesity may be less responsive to oxytocin. This trial will compare a high and low dose oxytocin dosing regimen for the induction of labor in women with obesity.
In 2019 VA mandated that all Veterans seeking mental health care have access to flexible family mental health services in VA (VHA directive 1163.04). This study aims to respond to this mandate by further improving an evidence-based PTSD treatment designed to decrease PTSD symptoms and improve relationship satisfaction for Veterans and their romantic partners. Brief Cognitive-Behavioral Conjoint Therapy (B-CBCT), an 8-session dyadic psychotherapy for PTSD, has been found to significantly reduce PTSD symptoms, but the effects of B-CBCT on relationship satisfaction are less reliable and robust. Pharmacological augmentation of psychotherapy utilizing intranasal oxytocin, a neurohormone that influences mechanisms of trauma recovery and social behavior, may help improve relationship satisfaction outcomes. If successful, the proposed study will advance knowledge of strategies for improving Veterans' quality of life by improving their intimate relationships along with PTSD symptoms.
This is a randomized, double-blind, placebo-controlled crossover pilot study of single-dose intranasal oxytocin (4 IU and 24 IU) in 18-60-year-old men and women with central diabetes insipidus to evaluate the effect of oxytocin on anxiety, depression and socioemotional functioning. Following a screening visit to determine eligibility, participants will return for three main study visits. During the main study visits, study participants will receive either oxytocin or placebo, followed by assessments of emotional behavior. Thirty participants will be equally randomized to one of six possible drug orders: 1. 4 IU oxytocin - 24 IU oxytocin - placebo 2. 4 IU oxytocin - placebo - 24 IU oxytocin 3. 24 IU oxytocin - 4 IU oxytocin - placebo 4. 24 IU oxytocin - placebo - 4 IU oxytocin 5. placebo - 4 IU oxytocin - 24 IU oxytocin 6. placebo - 24 IU oxytocin - 4 IU oxytocin
This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 12-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (1 spray per nostril, 4 times per day) for 12 weeks. Study visits include screening to determine eligibility, 2-part main study visits at baseline, week 8, and week 12, and safety check-in visits at weeks 1, and 4; phone calls at weeks 2, 6, and 10, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include appetite, behavioral, metabolic, and endocrine assessments.
Patients receiving oxytocin for induction or augmentation of labor will be studied with uterine EMG. The results of the EMG will be converted to an oxytocin-associated uterine stimulation index (uSI), which is intended to guide decisions for changing the dose of oxytocin. An expert panel will review the results of the oxytocin dosing actions, then assigned optimized actions throughout the labor. The uSI will be correlated with the optimal dosing actions.
This is a completed project which was initiated prior to January 18,2017 Background: Theoretical models of complicated grief (CG) suggest that maladaptive approach (e.g., perseverative proximity-seeking of the deceased) or avoidance (e.g., excessive avoidance of reminders) behaviors interfere with a person's ability to integrate the loss and recover from their loved one's death. Due in part to conflicting evidence, little mechanistic understanding of how these behaviors develop in grief exists. We sought to (1) identify behavioral differences between CG and non-CG groups based on implicit bias for grief-, deceased-, and social-related stimuli, and (2) test the role of the neuropeptide oxytocin in shaping approach/avoidance bias. Methods: Widowed older adults with and without CG completed an approach/avoidance task measuring implicit bias for personalized, non-specific, grief-related, and other stimuli. In a double-blinded, randomized, counterbalanced design, each participant attended both an intranasal oxytocin session and a placebo session. Aims were to (1) identify differential effects of CG and stimulus type on implicit approach/avoidance bias \[placebo session\], and (2) investigate interactive effects of CG, stimulus type, and oxytocin vs. placebo on approach/avoidance bias \[both sessions\].
The purpose of this study is to specifically investigate whether oxytocin and mechanical dilation decreases the rate of cesarean section compared to misoprostol and mechanical dilation for pregnancies at risk of fetal compromise
Posttraumatic stress disorder (PTSD) is a chronic, debilitating condition that disproportionately affects Veterans. Prolonged Exposure (PE) therapy is a "gold standard" treatment for PTSD. However, approximately one-third of Veterans fail to receive an adequate dose of treatment because they prematurely drop out of PE therapy. There is also room to improve PE treatment outcomes. Consistent with the VA Office of Research and Development initiative to develop effective treatments for PTSD, the proposed randomized clinical trial will examine the ability of oxytocin (as compared with placebo) combined with PE to reduce PTSD symptom severity, improve the rate of PTSD symptom reduction, and to enhance PE treatment retention and adherence. This two-site study will leverage the investments made in the nationwide rollout off PE therapy and has the potential to significantly improve mental health care among Veterans, advance the science in this area, and identify mechanisms underlying positive PTSD treatment response. Participants may choose to complete this research study via home-based telemedicine (HBT) care (i.e. service delivery to patients in their homes using consumer friendly, video-conferencing technology). HBT sessions will be delivered via standard desk, laptop computer, tablet, or smartphone using VA approved applications. All procedures that take place via telemedicine will be performed and completed as though they were in-person/in-office
The goal of this study is to test the effects of oxytocin on heart rate variability and pupil diameter, both of which have subtle effects on the activity rate of the autonomic nervous system.
This proposed research seeks to examine the behavioral and neural substrates of intranasal oxytocin compared to placebo on alcohol cue-induced alcohol and cigarette craving smokers with an alcohol use disorder (AUD). Non treatment-seeking smokers with an AUD will be recruited to participate in a between-subjects, placebo-controlled, randomized pilot functional magnetic resonance imaging (fMRI) study. Participants will undergo an fMRI scan in conjunction with an alcohol-olfactory cue-reactivity task. Secondary assessments will include alcohol and cigarette craving, alcohol and cigarette consumption, physiological measures (heart rate and blood pressure) and mood measures.
This study aims to determine when during gestation oxytocin receptor (OXTR) expression increases in the myometrium, which will contribute new insight to the management of obstetric hemorrhage and our understanding of normal and abnormal labor.
Schizophrenia has a devastating and disproportionate effect on veterans compared to the general US population. Some of the most disabling symptoms, such as low motivation, difficulty expressing emotions, and decreased ability to infer the mental states of others, cause poor social functioning. This means that veterans with schizophrenia have trouble navigating interpersonal interactions and building meaningful relationships in the community. Unfortunately, current antipsychotic medications typically only improve positive symptoms but fail to improve social functioning deficits, which are strong predictors of poor quality of life and functional outcomes. Oxytocin, a peptide found in the brain, plays an important role in social behavior and is known to moderate affiliation, stress, and learning across taxa. In this study, the investigators will test whether oxytocin could be an effective treatment for social functioning deficits in schizophrenia. The investigators will examine changes in brain activation to understand how oxytocin affects behavior and to predict which individuals may benefit from oxytocin treatment.
The proposed study is a randomized, double-blind proof of concept (PoC) study on the neural impact of intranasal oxytocin (OXT) administration for adolescents (age 14 to 18), demonstrating a clinically significant level of irritability as defined by a score of ≥4 on the Affective Reactivity Index (ARI). Planned enrollment is 80 subjects over 3 years.
This study will investigate if an intra-nasal nose spray of the drug oxytocin can decrease the amount of pressure needed from the automatic Continuous Positive Airway Pressure (CPAP) device while sleeping decreasing some of the harmful effects of low oxygen in people with sleep apnea. This study will last 35 nights and involves spending three nights in the sleep lab at George Washington University. There are no additional costs to participants and no compensation for being involved in the study.
This study investigates the roles of oxytocin pathways in human-animal interaction.
The purpose of this study is to examine the effects of mindfulness training and a drug called oxytocin on smoking.
To further test the effectiveness of oxytocin in heavy drinkers, half of the cohort in the proposed study will meet criteria for heavy drinking (\>35 standard drinks/week \[men\], \>28 standard drinks/week \[women\] for at least 4 consecutive weeks). However, the investigators think it important to expand the cohort of the proposed study to include subjects with moderate Alcohol Use Disorder (AUD) who meet lower drinking criteria so the outcome of the study will be relevant to a larger percentage of individuals who have AUD. The lower drinking criteria will be minimum of 14 drinks/week (women) or 21 drinks/week (men) with an average of at least two heavy drinking days (≥5 standard drinks for men and ≥4 standard drinks for women) each week in the 4-week period prior to screening. As in the R21-funded Preliminary Study, individuals recruited from the community who meet study criteria based on assessment during a screening clinic visit will be randomized to twice a day (BID) intranasal oxytocin or intranasal placebo during a subsequent clinic visit. After instruction by research staff during the randomization clinic visit, subjects will self-administer intranasal treatments from blind-labeled spray bottles that they take home. During clinic visits at 1, 2, 3, 4, 6, 8, 10, and 12 weeks after randomization, drinking since the last visit will be quantified and other measures summarized above will be obtained. Subjects will self-administer test intranasal treatments for 12 weeks. Drinking will also be quantified during clinic visits at 6 and 12 weeks after cessation of intranasal treatments. This clinical trial will be the first adequately powered, double blind, placebo-controlled trial examining the efficacy and tolerability of BID intranasal oxytocin (40 IU/dose; 80 IU/d) on alcohol drinking in AUD. The trial will also be the first to prospectively examine the effects of intranasal oxytocin on anxiety symptoms in individuals with AUD.
Mothers who were enrolled in the Mood, Mother and Infant study will be eligible to participate in the 6-year follow-up maternal visit. At the time of this visit, mothers will be randomized to a single 24 IU dose of nasal oxytocin or placebo. Following administration of the study drug, women will participate in the Trier Social Stress Test (TSST), and blood samples will be collected to quantify HPA axis reactivity.
The purpose of this study is to assess the safety, tolerability and effects on behaviour of Syntocinon given intranasally (by a spray into the nostrils) compared to placebo (an inactive saline substance that contains no medication) in participants with frontotemporal dementia/Pick's disease. This study will take place in approximately 15 centres across Canada and the United States. Approximately 112 patients in total will be enrolled in this study. In the first phase we will examine which of three different dosing schedules of oxytocin may be more effective. In the second phase of the study, patients entering the study will be randomized to the oxytocin dosing schedule that appeared most effective in the first phase.
