The investigator proposes to 2D6 (Cytochrome P-450 Isoenzyme 2D6) genotype and phenotype a group of active duty service members and assess the effects on primaquine metabolism.
The purpose of this study is to evaluate the effectiveness of bacteria called Lactobacillus GG, a Probiotic, in preventing the growth of resistant bacteria in the digestive tract in patients on broad spectrum antimicrobials.
This is an open-label, randomized, 3-period crossover, single dose study. Three (3) single doses of AZD3293 (2 different tablet formulations, and an oral solution) will be administered with a washout period of at least 1 week between the doses to investigate the relative bioavailability of AZD3293 after administration via 2 tablet formulations compared with oral solution and to evaluate basic systemic pharmacokinetic parameters of the tablet formulations compared to the oral solution of AZD3293. The safety and tolerability of AZD3293 in healthy subjects will also be assessed in the study. AZD3293 is being developed for the treatment of Alzheimer's disease
This study is a single-center, open-label, 3-group, fixed-sequence drug-drug interaction study to assess the effect of coadministration of multiple-dose itraconazole or diltiazem on the single-dose PK of AZD3293 and the effects of coadministration of single- and multiple-dose AZD3293 on the single-dose PK of midazolam. The study will also evaluate the safety and tolerability of single and multiple oral doses of AZD3293, alone and in combination with itraconazole, diltiazem, and midazolam in healthy young subjects.AZD3293 is being developed for the treatment of Alzheimer's disease
This is a pilot study to finalize methods for a larger study being planned for the future. This research is being done to characterize performance of tasks, brain functioning, and the effects of psilocybin in individuals with a long-term meditation practice. There are three different parts of the pilot study: 1. Effects of psilocybin on psychological function: This version of the pilot study will involve 1 or 2 day-long psilocybin sessions, and several meetings and data assessment visits. You will make a total of about 5 to 10 visits to our research unit (the BPRU on the Johns Hopkins Bayview Campus). 2. Performance on behavioral and cognitive tasks: This version of the pilot study will involve completing various behavioral and cognitive tasks at our research unit. You will make a total of about 1-10 visits to our research unit (the BPRU on the Johns Hopkins Bayview Campus). 3. Brain functioning: This version of the study will involve 1 to 3 brain imaging (MRI) measurements. You will make a total of about 2 to 5 visits to our research unit (the BPRU on the Johns Hopkins Bayview Campus). The MRI measurements will be taken at the F.M. Kirby Research Center at the Kennedy Krieger Institute (across the street from the Johns Hopkins Hospital). People who are between the ages of 25 and 80 years old, who have a current, regular meditation practice, and who meet the medical requirements may join.
This randomized, double-blind, placebo-controlled trial will seek to determine the efficacy of abatacept in GCA. To examine this objective, 62 eligible patients who have newly diagnosed or relapsing GCA within 8 weeks prior to screening will be randomized at a 1:1 ratio to receive subcutaneous abatacept 125mg/week or placebo. Patients who achieve remission will remain on their blinded assignment for 12 months at which time abatacept/placebo will be stopped. Patients who do not achieve remission by Month 3, who experience a relapse within the first 12 months will have the option of receiving open-label abatacept for a maximum of 12 months.
This pilot study will determine the feasibility of implementing a combinatory rehabilitation strategy involving testosterone replacement therapy (TRT) with locomotor training (LT; walking on a treadmill with assistance and overground walking) in men with testosterone deficiency and walking dysfunction after incomplete or complete spinal cord injury. The investigators hypothesize that LT+TRT treatment will improve muscle size and bone mineral density in men with low T and ambulatory dysfunction after incomplete or complete SCI, along with muscle fundtion and walking recovery in men with T low and ambulatory dysfunction ater incomplete SCI.
Co-occurring post-traumatic stress disorder (PTSD) and major depressive disorder (MDD) is the most common response to trauma; it is associated with poor clinical outcomes and substantial human disability. Veterans with both PTSD and MDD (PTSD+MDD) have been shown to be at much greater suicidal risk than individuals with only one of these disorders. Ketamine given as repeated infusions has been shown to be effective in rapidly reducing PTSD and MDD symptoms in treatment resistant PTSD+MDD individuals. However, knowledge about the mechanisms underlying comorbid PTSD and MDD remain limited. The purpose of this study is to use repeated ketamine infusions as a probe to validate a model of PTSD+MDD that focuses on neuroanatomy and executive functioning.
The primary objective of this clinical trial is to determine if treatment with ubiquinol, a form of coenzyme Q10, improves the physical function of men and women Veterans suffering from Gulf War Illness (GWI). The primary outcome measure is a change from baseline on the Short Form Health Survey 36-item (SF-36), with respect to physical functioning and symptoms. Secondary outcome measures include changes from baseline levels on GWI-associated biomarkers in peripheral blood and GWI-associated symptoms of chronic pain, fatigue, insomnia, activity level, and cognitive and mental functioning.
This study is geared toward characterizing the recovery of brain activity and cognitive function following treatments of electroconvulsive therapy and ketamine general anesthesia.
The purpose of this study is to evaluate the safety and pharmacokinetics of UV-4B oral solution when administered to healthy subjects three times a day (TID) for 7 days.
This application seeks renewed support for MH59803, "Dopaminergic substrates of startle gating across species," to extend a clear path of "bench-to-bedside" progress towards a critical paradigm shift in therapeutic models for schizophrenia (SZ) and schizoaffective disorder, depressed type (SZA): the use of Pharmacologic Augmentation of Cognitive Therapies (PACTs). This novel therapeutic strategy for SZ/SZA directly addresses the need for more effective treatments for this devastating disorder. MH59803 has investigated the neural regulation of laboratory-based measures of deficient information processing in SZ/SZA patients, using rodents and healthy human subjects (HS) to explicate the biology of these deficits, and to establish a rational basis for developing novel therapies for SZ/SZA. In its first 9 years, MH59803 studies of the neural regulation of prepulse inhibition (PPI) of startle in rats focused on basic neurobiological and molecular mechanisms. Over the past 2 years of support, MH59803 studies moved "from bench-to-bedside," focusing on dopamine (DA) agonist effects on PPI and neurocognition in HS, and their regulation by genes identified in cross-species studies. These studies detected biological markers that predict PPI-enhancing and pro-cognitive effects of the DA releaser, amphetamine (AMPH) in humans, leading to specific predictions of AMPH effects on PPI, neurocognition and Targeted Cognitive Training in SZ/SZA patients. If confirmed in the present application, these predictions could help transform therapeutic approaches to SZ/SZA. This renewal application of MH59803 thus reflects a logical progression of studies at systems and molecular levels, translated first to HS, and now to potentially transformative therapeutic models in SZ/SZA patients.
The relationship between depression and trauma is well established. Co-occuring depression and post-traumatic stress disorder (PTSD) are associated with more severe symptoms and lower levels of functioning. Veterans with both depression and PTSD have been shown to be at much higher risk of suicide than individuals with only one of these disorders. Ketamine has been shown to have rapid antidepressant effects and also therapeutic action over PTSD symptoms. The purpose of this study is to see whether ketamine, when given as repeated infusions, can produce quick and sustained improvement in depression and PTSD symptoms for individuals who have not had their symptoms effectively treated by current treatments.
The purpose of the study is to evaluate the safety and feasibility of administering SB-728mR-HSPC after conditioning with busulfan.
This is an observational registry to further characterize the safety profile of patients with chronic myeloid leukemia in the chronic phase (CP-CML), accelerated phase (AP-CML), blast phase (BP-CML), or Ph+ALL treated with Iclusig (ponatinib) in routine clinical practice in the US. The registry is focused on analysis of vascular occlusive events.
Our primary aim is to assess the feasibility of initiating treatment in the ED with extended-release naltrexone (XR-NTX) plus care management (CM) vs. standard care and continuing care in cooperation with clinic providers as well as how best to assess outcomes. Secondarily, the investigators will explore its effect on various health outcomes (healthcare utilization and engagement, expenditures, drinking and consequences, quality of life) as well as the association of patient-level characteristics (e.g. sex, race, baseline drinking, health and psychosocial factors, mu opioid receptor genotype) with effectiveness. Determining both how to implement XR-NTX+CM and rigorously test its effects in the ED (phase 1) is essential before planning a large-scale effectiveness trial (phase 2).
The main aim of this study was to evaluate the efficacy and safety of adding ribociclib to fulvestrant in men and postmenopausal women with hormone receptor positive (HR+), HER2-negative advanced breast cancer.
The current protocol is a pilot study of the effects and possible utility of psilocybin-facilitated experiences for professional religious leaders. We hypothesize that religious professionals, given their interests, training, and life experience, will be able to make nuanced discriminations of their psilocybin experiences, thus contributing to the scientific understanding of mystical-type experience. As we better characterize the phenomenology of psilocybin-induced mystical experiences, we may apply this knowledge to improve potential treatment studies in the future. A primary objective is to investigate changes in psychological functioning, spirituality, health, well-being, prosocial attitudes and behavior in professional religious leaders that may occur after receiving psilocybin under supportive conditions. A secondary objective is to determine whether participants who report having had the strongest mystical-type effects during psilocybin sessions will show the largest positive changes in the Interim Questionnaire.
This is a prospective, multicenter, randomized, double-blind, placebo-controlled Phase 3 study designed to evaluate the safety and efficacy of Mesoblast's rexlemestrocel-L alone or combined with hyaluronic acid (HA) in participants with chronic low back pain (\> 6 months) associated with moderate radiographic degenerative changes of a disc.
This randomized phase III trial studies 90-yttrium ibritumomab tiuxetan and combination chemotherapy compared with combination chemotherapy alone before stem cell transplant in treating patients with diffuse large b-cell non-Hodgkin lymphoma that has returned after a period of improvement. Radioactive substances linked to monoclonal antibodies, such as 90-yttrium ibritumomab tiuxetan, can bind to cancer cells and give off radiation which may help kill cancer cells. Drugs used in chemotherapy, such as carmustine, etoposide phosphate, cytarabine, and melphalan (BEAM), 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. It is not yet known whether 90-yttrium ibritumomab tiuxetan and BEAM before a stem cell transplant are more effective than BEAM alone in treating patients with diffuse large b-cell non-Hodgkin lymphoma.
The overall objective of this study is to define an effective therapeutic approach, using currently available medication, to prevent or mitigate the loss of bone mass and bone strength that occurs after acute spinal cord injury.
Study to evaluate the safety, tolerability, and pharmacokinetics of TAS-102 in patients with advanced solid tumors and varying degrees of renal impairment.
Study to evaluate the safety, tolerability, and pharmacokinetics of TAS-102 in patients with advanced solid tumors and varying degrees of hepatic impairment.
This is a Phase IV, multicenter, non-interventional, non-randomized, prospective, observational study in an adult population (patients \>18 years old) of men and women who have been diagnosed with clinically overt PV and are being followed in either community or academic medical centers in the United States who will be enrolled over a 12-month period and observed for 36 months from the date the last patient is enrolled.
The purpose of this study is to determine whether testosterone plus finasteride treatment will improve musculoskeletal health, neuromuscular function, body composition, and metabolic health in hypogonadal men who have experienced ambulatory dysfunction subsequent to incomplete spinal cord injury. The investigators hypothesize that this treatment will improve bone mineral density, enhance muscle size and muscle function, and improve body composition, without causing prostate enlargement.
The current protocol is a pilot study of the effects and possible utility of psilocybin-facilitated experiences for professional religious leaders.
To compare the effect of ticagrelor versus aspirin on the change in peak walking time, evaluated on the graded treadmill test, from one to 26 weeks post-revascularization in patients with peripheral artery disease who have undergone endovascular revascularization for moderate to severe claudication or ischemic rest pain.
Low testosterone is a condition that occurs when the body is unable to produce sufficient quantities of testosterone. The medical name for low testosterone is hypogonadism. Hypogonadism can be caused by many factors. Symptoms include: decrease in libido, lack of energy and mood swings. The goal of testosterone replacement therapy is to return testosterone levels to the normal range and relieve symptoms.
The purpose of this study is to determine if a year of alendronate treatment will maintain or increase bone mass density (BMD) compared to baseline BMD values in people with chronic spinal cord injury (SCI). This study will also investigate 1) if alendronate therapy will increase bone strength in people with chronic SCI, 2) the number of participants with adverse events from alendronate, and 3) the effects of alendronate on serum markers of bone metabolism.
The primary objective of the study is to evaluate the safety and tolerability of voxilaprevir (formerly GS-9857) alone or with sofosbuvir (SOF)/velpatasvir (VEL) fixed dose combination (FDC) and antiviral activity of voxilaprevir in adults with genotype 1, 2, 3, 4 hepatitis C virus (HCV) infection. All participants will be monitored for up to 48 weeks after the last dose.
