The purpose of this research study is to evaluate the efficacy and safety of an empagliflozin dosing regimen and one dose of linagliptin in patients with type 2 diabetes who are aged 10 to below 18 years and are currently taking metformin, insulin or both drugs (DINAMO TM) or who are treatment naïve or not on active treatment after metformin withdrawal (DINAMO TM MONO) . Empagliflozin and linagliptin are both approved for use in adult patients with type 2 diabetes. This study will assess how well empagliflozin and linagliptin work by finding out how these treatments affect blood glucose (sugar) levels compared to placebo (a pill that contains no active drug), in children and adolescents. Empagliflozin and linagliptin are considered investigational products in this study since while they have been approved for use in adults, they have not been approved for children and adolescents due to lack of clinical studies in this specific population. Patients with type 2 diabetes have higher levels of blood glucose (sugar) than patients who do not have this disease. The high level of sugar in the blood can lead to serious short-term and long-term medical problems. The main goal of treating diabetic patients is to lower blood glucose to a normal level. Lowering and controlling blood glucose help prevent or delay complications of diabetes such as heart disease, kidney, eye and nerve diseases, and the possibility of amputation. Empagliflozin is a drug that helps to reduce blood glucose (sugar) levels by causing glucose to be excreted in the urines. Linagliptin works by increasing the production of insulin (a hormone that controls the level of blood glucose) after meals when blood glucose (sugar) levels are too high. This helps to lower blood sugar levels. The subject will either receive one of the active study drugs or a placebo. This study will be double blind; this means that neither the subject, nor the study doctor will know which treatment the subject will receive. Which treatment the subject receives is decided by a computer, purely by chance; this is called a "random assignment". For this study, there will first be a screening visit, followed by a 2-week placebo run-in period (all subjects will take placebo once daily). This run-in period is designed to ensure subjects are able to take the study drugs as described in the study protocol. Thereafter there will be a 26-week treatment phase (week 1-week 26) and a 26-week safety extension period (week 27-week 52). Following this there will be a follow-up visit at week 55. On Day 1 after the placebo run-in phase, the subject will be randomly assigned to receive one of the 3 treatments: empagliflozin 10 mg, linagliptin 5 mg or placebo in a blinded manner. This treatment will continue up to week 14. Then after week 14, the subject will be assigned to receive one of the following 4 treatments: empagliflozin 10 mg, empagliflozin 25 mg, linagliptin 5 mg or placebo in a blinded manner. The drugs assigned after week 14 will be the same drugs as on Day 1 but some subjects will receive a higher dose of empagliflozin. After the completion of the 26-week treatment period, the subject will enter a 26-week safety extension period. The same active treatment that the subject had been assigned to at week 14 visit will be continued. Subjects assigned to placebo on Day 1 will be randomly assigned to receive one of the 3 active treatments: empagliflozin 10 mg, empagliflozin 25 mg or linagliptin 5 mg in a blinded manner. This safety extension period is primarily designed to provide additional information on how well empagliflozin and linagliptin are tolerated. Following the treatment phases, there will be a follow-up visit at week 55 Intervention model description: Eligible subjects with HbA1c of 6.5% to 10.5% at screening will be randomized in a 1:1:1 ratio to receive empagliflozin 10 mg, linagliptin 5 mg or placebo. HbA1c assessment will be performed at Week 12. All subjects with Week 12 HbA1c \< 7% will remain on previously assigned randomized treatment. Subjects taking empagliflozin with Week 12 HbA1c \>= 7% will be re-randomized in a 1:1 ratio to continue on the low dose treatment (empagliflozin 10 mg) or up-titrate to the high dose treatment (empagliflozin 25 mg). Subjects taking linagliptin or placebo with Week 12 HbA1c \>= 7% will remain on previously assigned treatment. All subjects will get new medication kits dispensed at Week 14 to maintain the blinding. At Week 26, all subjects previously assigned to placebo will be re-randomized in a 1:1:1: ratio to receive one of the active treatments: empagliflozin 10 mg, empagliflozin 25 mg or linagliptin 5 mg. All subjects will get new medication kits dispensed at Week 14 to maintain the blinding.
NCT04732247
Naval Special Warfare (NSW) operators are exposed to a variety of extreme environmental conditions and intense physical demands. In addition to breathing high pressure gases at depth, prolonged cold water immersion and inadequate recovery from sustained physical exertion negatively impact individual and team performance. Biotechnologies that could mitigate the effects of cold as well as support physical recovery represent a significant unmet need for the NSW operational community. Oxytocin (OT) has a wide range of actions both locally in the brain and peripherally in the body including skeletal muscle. These peripheral effects can be mediated by classic ligand-receptor activation given the abundant expression of the oxytocin receptor in peripheral tissues, along with local expression of OT in peripheral tissues where it is likely to act in an autocrine manner. Exogenous OT via intranasal administration is FDA Investigational New Drug (IND)-approved and has been demonstrated as an easy and safe method to increase circulating OT concentrations that may augment actions on peripheral tissues. Due to the pleiotropic effects of OT on whole body metabolism, thermogenesis, stress responses, pain, mood, inflammation, appetite, glycemic control, skeletal homeostasis, and skeletal muscle repair and regeneration, there is increasing interest in the administration of exogenous OT for benefits to human health, performance and resilience. However, the biological mechanisms by which OT exerts tissue-specific effects (e.g., skeletal muscle) remain poorly understood, particularly in humans. This project is designed to significantly advance this understanding while testing the central hypothesis that intranasally administered OT attenuates systemic and skeletal muscle oxidative stress and inflammation induced by the combined stressor of resistance swim exercise and hyperoxia.
NCT01910402
This study is designed to demonstrate the non-inferior antiviral activity of DTG/ABC/3TC fixed dose combination (FDC) once daily (OD) compared to atazanavir plus ritonavir (ATV+RTV) and tenofovir disoproxil fumarate/emtricitabine fixed dose combination (TDF/FTC FDC) OD in HIV-1 infected, ART-naïve women over 48 weeks. This study will also characterize the safety and tolerability of DTG/ABC/3TC FDC compared to ATV+RTV+TDF/FTC FDC. Sufficient number of subjects will be screened in order to ensure a total of approximately 474 subjects will be randomized (237 in each study arm)

NCT05379179
This is a pilot study to evaluate pain responses from two different approved medications (ketamine and fentanyl) in the treatment of pain after rattlesnake envenomation (RSE). Both medications are currently used in standard practice to treat both acute and chronic pain and are options for pain management after RSE. Multiple studies exist showing ketamine to be both safe and effective for the treatment of acute pain, and to be as good as or better than opioids for this indication. The specific comparison of ketamine to fentanyl, however, has never been studied for the treatment of acute pain after rattlesnake envenomation in the United States. The investigators plan to measure pain scores after a single dose of ketamine or fentanyl in patients shortly after being envenomated, followed by continued treatment of pain guided by the treating doctor. There will be no restrictions on additional pain medications given and no other changes to the treatment of these patients during their hospitalization. This research is important because pain after RSE can be difficult to control and may require frequent, high doses of opioids for several days. An effective non-opioid medication would be helpful both to better-control pain and to reduce exposure to opioids in this patient population. This study will compare patient-reported pain scores after receiving a single dose of ketamine or fentanyl in patients with rattlesnake bites who have been admitted to the toxicology service at Banner - University Medical Center Phoenix (BUMCP).
NCT05387707
This is a two-part, multicenter, randomized, double-blind study to evaluate the efficacy and safety of oral difelikefalin as adjunct therapy to a topical corticosteroid (TCS) for moderate-to-severe pruritus in adult subjects with atopic dermatitis (AD).
NCT00630032
RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) and giving them after surgery may kill any tumor cells remaining after surgery. It is not yet known whether docetaxel is more effective than ixabepilone when given after surgery and combination chemotherapy in treating breast cancer. PURPOSE: This randomized phase III trial is studying giving combination chemotherapy followed by docetaxel or ixabepilone to compare how well they work in treating patients who have undergone surgery for nonmetastatic breast cancer.

Assessments include safety, blood sampling, physical examination, vital signs, anthropometric body measurements \& patient/caregiver quality of life questionnaires Participants will received treatment with Recifercept for 12 months. All participants who complete the study and in the opinion of the investigator, continue to have a positive risk:benefit profile, will be offered to enroll into an open-label extension (OLE) study. A PK cohort will include 12 participants who will randomly receive a single dose of 3 mg/kg of Phase 2 study (process 1c) formulation and a single dose of 3 mg/kg of the proposed Phase 3 (process 2) study formulation in a cross over study. Dose of the cohort could be changed due to emerging safety and efficacy data in the study.
NCT05049330
Cervical spine injuries (CSI) are serious, but rare events in children. Spinal precautions (rigid cervical collar and immobilization on a longboard) in the prehospital setting may be beneficial for children with CSI, but are poorly studied. In contrast, spinal precautions for pediatric trauma patients without CSI are common and may be associated with harm. Spinal precautions result in well-documented adverse physical and physiological sequelae. Of substantial concern is that the mere presence of prehospital spinal precautions may lead to a cascade of events that results in the increased use of inappropriate radiographic testing in the emergency department (ED) to evaluate children for CSI and thus an unnecessary, increased exposure to ionizing radiation and lifetime risk of cancer. Most children who receive spinal precautions and/or are imaged for potential CSI, and particularly those imaged with computed tomography (CT), are exposed to potential harm with no demonstrable benefit. Therefore, there is an urgent need to develop a Pediatric CSI Risk Assessment Tool that can be used in the prehospital and ED settings to reduce the number of children who receive prehospital spinal precautions inappropriately and are imaged unnecessarily while identifying all children who are truly at risk for CSI.

NCT03651830
Objective/Hypotheses and Specific Aims: The primary aim of this proposal is to determine whether a PFE can be used to predict foot preference and mobility outcomes with corresponding commercial prosthetic feet in people with a unilateral transtibial amputation (TTA). Secondarily, the investigators aim to determine whether a brief trial of commercial prosthetic feet would be able to similarly predict longer-term foot preference and mobility outcomes with those feet. Study Design: The investigators will use a participant blinded cross-over study with repeated measurements. Participants with TTA will be enrolled at each of the three study sites: two VA sites (Puget Sound and Minneapolis), and one Department of Defense site (Center for the Intrepid). Participants will complete up to 6 visits. After an initial assessment visit, participants will be assigned to the high or low mobility group, and then during visit 2 they will be randomized to use the PFE in three foot modes or the three corresponding actual (commercially available) feet during walking tests in the laboratory. During visit 3 participants will repeat the procedures in the other condition (e.g., PFE if Day 2 included actual feet testing). At the end of visit 3 participants will be fit with one of the actual feet and wear it at home and in the community for approximately two weeks. At visit 4 participants will be fit with the next actual foot and repeat the 2 week use window. The same process will be followed for the final foot at visit 5, and the study foot will be returned at visit 6. Participants' preference, satisfaction and perceived mobility, and functional mobility will be measured and compared across all foot conditions (emulated and actual). After participants complete the procedures detailed above, they may be eligible to be invited to participate in follow-up phone interviews. A subset of participants may also be invited to participate in follow-up biomechanical data collection comparing the PFE foot conditions to the respective actual prosthetic feet during walking. Additionally, a subset of participants may also be invited to participate in follow-up data collection comparing prosthetic foot conditions of different stiffness categories.
