Filter by:The purpose of this study is to assess the effects of simultaneous administration of oral aspirin and oral ketamine as a therapeutic for those with Treatment Resistant Depression.
This is a randomized, single-dose, open-label, parallel-group study. Patients will undergo the screening evaluations to determine eligibility within 28 days prior to study drug administration. Approximately 80 eligible patients will be randomized in a 1:1:1:1 ratio to 1 of 4 treatment groups.
This is a randomized, multiple-dose, open-label, parallel-group study. Subjects will undergo screening evaluations to determine eligibility within 28 days prior to study drug administration. Approximately 280 eligible subjects will be randomized in a 1:1 ratio into 1 of 2 treatment groups. Subjects will be admitted to the clinical facilities the day before dosing (Day 0), and will be randomized and receive the first dosing on Day 1. Subjects will stay at site till Day 2 after PK collection. All subjects will return to the clinical sites at designated study days for dosing, PK sample collections and assigned clinical activities. All subjects randomized to LY03010 treatment group will receive the first dose of 351 mg LY03010 by IM injection on Day 1 in the deltoid muscle, followed by five (5) monthly dosing of 156 mg LY03010 in the gluteal muscle with the last dose on Day 141. All subjects randomized to SUSTENNA treatment group will receive the first dose of 234 mg SUSTENNA by IM injection on Day 1 in the deltoid muscle, and a second IM dose of 156 mg SUSTENNA on Day 8 in the deltoid muscle, followed by five (5) monthly IM dosing of 156 mg of SUSTENNA in the gluteal muscle with the last dose on Day 148. End of Study (EOS) visit for LY03010 treatment group will be on Day 169, 28 days after last dosing day; End of Study for SUSTENNA treatment group will be on Day 176, 28 days after last dosing. At EOS visit, subjects will complete the study after a series of assigned clinical assessments. A 30-day follow up call will be conducted by the clinical research staff to ensure participant's well-being.
To compare responses to acute oral doses of ethanol in healthy young adults who experience mainly stimulant subjective effects from the drug or mainly sedative effects.
To evaluate the relationship of extraversion to both the acute subjective and behavioral effects of alcohol, and the neural reactivity to the anticipation of reward.
Background: The drug empagliflozin treats diabetes. It lowers blood sugar by increasing glucose the kidneys excrete. This increases levels of ketones formed in the blood. The body makes ketones when it does not have enough glucose for fuel. The brains of many people with age-related diseases like Alzheimer's do not use glucose well. Brain use of ketones might improve mental ability. We investigated how empagliflozin affects ketone levels, which could lead to ways to improve brain health as people age. Objectives: To study how taking empagliflozin affects systemic and brain metabolism including ketone levels in people without diabetes. Eligibility: Adults at least 55 years old without diabetes Design: After a screening Visit, eligible participants were admitted to the NIA Clinical Unit during Visits 1 (baseline), 2 (first dose) and 3 (last/14th dose). On each Visit, blood draws were performed and circulating metabolites and hormones were repeatedly measured over 34-hour periods. Using plasma from fasting state only, we isolated total and neuronal-origin extracellular vesicles to measure proteins of the IGF-1 and insulin signaling cascades. Furthermore, on each Visit, we performed magnetic resonance spectroscopy (MRS) to measure concentrations of a plethora of metabolites in the brain. Between Visits 2 and 3, participants were taking the drug at home. A continuous glucose monitoring device was placed to detect potential glucose fluctuations while at home. The study was concluded for participants after the end of Visit 3.
The addition of tDCS as an adjunct to pharmacotherapy is a novel approach but one that is grounded in a growing evidence-base.The primary objective of this research is to provide preliminary evidence of the effectiveness of tDCS as an adjunct treatment to pharmacotherapy for smoking cessation. The investigators hypothesize that the addition of active tDCS to the left DLPFC will improve the effectiveness of varenicline as reflected by higher quit rates at end of treatment compared to the sham group. Smoking status will be biochemically confirmed at various time points using expired cotinine measures. Furthermore, the investigators will be collecting neuroimaging (fMRI) data as well as measures of attentional bias to explore the neurological and physiological correlates from using adjunct tDCS and varenicline therapy.
Peripheral nerve blocks with use of USG allowed visualisation of the structures and nerves and made the block administrations safe, quick and comfortable. However there are few publications concerning the minimum local anesthetic volume capable of providing blocks. In this study the investigastors aimed to find Minimum Effective Volume Of Local Anesthetic For Ultrasound-Guided İnfraclavicular Approach for Brachial Plexus Blockade in upper limb operations.
A randomized, double-blind, placebo controlled parallel group clinical trial evaluating the effects of acute treatment with a PCSK9 inhibitor (alirocumab) versus placebo on low-density lipoprotein (LDL) in 100 high-risk patients presenting with STEMI and referred for primary PCI. The objective is to determine the effect of acute, rapid lowering of LDL cholesterol with alirocumab added to high dose statin therapy in patients with STEMI undergoing primary PCI. The hypothesis is that, in patients with STEMI undergoing primary PCI, rapid lowering of LDL cholesterol with a PCSK9 Inhibitor (alirocumab) initiated in the acute setting pre-PCI, will favourably affect LDL cholesterol concentrations compared with placebo.
Female inability to conceive a child. The purpose of this prospective randomized, double-blinded, double dummy, two-arm cross-over study is to investigate the difference on histological, transcriptional and immunological level in endometrium between 3x10mg Dydrogesterone oral tablets and 3x200 mg Micronized progesterone intravaginal capsules for the luteal support in egg cell donors. Beside that, the pharmacokinetics, the impact on the peripheral immunology (by blood sampling) and the microbiota (by genital swabs) will be investigated.
