Filter by:The investigators are doing this project to investigate potential neurophysiological synergy effects between mindfulness meditation and psychedelics. Previous studies have found that both mindfulness and psychedelics like psilocybin modulate neural activity and connectivity of the same brain network. However, little is known about the potential interactions between mindfulness meditation and psychedelics. The indigenous plant preparation "Ayahuasca" is particularly interesting for the combination with mindfulness meditation. It contains two components, N,N-dimethyltryptamine (DMT) and harmine, which are very similar to the body's own messenger substance serotonin and increase its effect in the body. The investigators would now like to find out how these corresponding networks change in experienced meditators after DMT/Harmine-enhanced mindfulness meditation and how this affects their subjective experience. For this functional MRI imaging will be performed, as well as psychometric assessments and detailed experiential interviews before and after a three-day meditation retreat. Participants will be randomly assigned to one of two groups. One group receives DMT and harmine during the sitting meditation on the second day, the other group receives a corresponding placebo. Neither the participants nor the investigator know who will receive a placebo or the combination of DMT/harmine on the day of the experiment. The pre- and post-measurements of the MRI imaging and psychometric questionnaires of the DMT/Harmine group are compared with those of the placebo control group. By examining the synergistic effects of mindfulness meditation and DMT/harmine, the aim of this study is to contribute to a comprehensive understanding of the neurophenomenology of rare and inaccessible phenomena of consciousness.
The purpose of the study is to evaluate the safety, tolerability and drug levels of single, oral doses of BMS-986447 in healthy participants.
This study will assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of single ascending doses (SADs) of ALXN1920 subcutaneous (SC) and of a single dose of ALXN1920 intravenous (IV) in healthy adult participants.
A research study to investigate how quickly and to what extent different compositions of the study medicine ziltivekimab are absorbed, transported, and eliminated from the body. Ziltivekimab is not yet approved for market. The study medicine will be injected under the skin (this is called subcutaneous administration). Two different administration methods will be compared: a syringe and a pen-injector. A pen-injector is a device that is developed to make injections more easy and convenient. They are for example used by diabetes patients to inject insulin. It will also be investigated how safe ziltivekimab is and how well it is tolerated when it is used by healthy participants. Ziltivekimab has already been administered to patients with chronic kidney disease or rheumatoid arthritis. The current study will be the first study where ziltivekimab will be given to healthy participants.
The purpose of the study is to evaluate the effect between two different single doses of mavamten in healthy participants.
This study will assess the potential drug-drug interaction (DDI) between ALXN2040 and rosuvastatin.
In this study, a known investigational medicine called 'semaglutide' will be tested in 2 drug concentrations of 0.68 milligram per milliliter (mg/mL) and 1.34 mg/mL. Both drug concentrations are tested for the treatment of type 2 diabetes. The U.S. Food and Drug Administration (FDA), has approved semaglutide in prefilled pen-injector form. Currently, the drug concentration of 1.34 mg/ml can be prescribed in some countries including U.S. The objective of the study is to compare the amount of investigational drug taken up in the body for the 2 drug concentrations. Participants will be divided by chance into 2 groups. Group A will receive a single dose of 0.5 mg semaglutide of the drug concentration 1.34 mg/mL in the first study period; and will receive a single dose of 0.5 mg semaglutide of the drug concentration 0.68 mg/mL in the second study period. Participants assigned to group B will receive the two drug concentrations in the reverse order. Participants will get 1 subcutaneous injection on Day 1 of each of the two study periods. The two injections are separated by 7-11 weeks. The study will last up to approximately 87 to 141 days for each participant. This includes a screening period (up to 4 weeks), study period 1 (5 weeks), washout period (2-6 weeks), and study period 2 (5 weeks). At some periods during the study, participant should not get vaccinations. Participant should agree on timing of vaccination with study doctor. Women cannot take part if pregnant, breast-feeding or plan to get pregnant during the study period.
The purpose of this study is to evaluate the safety, tolerability, drug levels and drug effect of BMS-986278 in healthy adult participants and Japanese participants.
The purpose of this study is to assess the effects on the single-dose drug levels of mavacamten in healthy participants.
The purpose of this clinical trial is to learn about how much PF-07081532 will be taken up and processed by healthy male participants. The study consists of two parts, called study periods. In Period 1, participants will take one dose of PF-07081532 by mouth. In Period 2, participants will take one dose by mouth and one dose as an injection through a vein at the study clinic. In Period 1, participants will stay at the clinic site for up to 21 days. In Period 2, they will stay at the clinic site for 7 days. During their stays, participants will have their blood, urine, and feces collected by the study doctors several times. We will measure the level of PF-07081532 in participants' blood, urine, and feces samples. This will help us know how much the study medicine is getting taken in by the body. At the end of the study, participants will be contacted by phone to check in. Participants will be involved in this study for about 12 weeks.
