Filter by:The primary purpose of the study is to evaluate the effect of increased metabolizing enzyme (cytochrome P450 [CYP] 3A4) due to carbamazepine, a strong CYP3A4 inducer, on the pharmacokinetics (PK) of darigabat in healthy adult participants.
This study aims to determine the safety, tolerability, and pharmacokinetics of single doses of Lucid-21-302 in healthy adult volunteers. This study will also investigate the effects of food in healthy volunteers.
In this study, a known investigational medicine called 'semaglutide' will be tested in 2 different tablet versions. In addition to semaglutide, the tablet versions contain different helping agents in different amounts. Both tablet versions have a helping agent called SNAC. The main aim of this study is to investigate semaglutide of 4 different doses in a new tablet by determining the amount of semaglutide in the blood and compare the concentration in the blood for the new tablet with the tablet currently investigated in a phase 3b study (current version). For this purpose, the amount of semaglutide in the blood will be measured after multiple doses of semaglutide, at different doses. Which doses participant will get will be decided by chance. The study will have 4 groups (A-D) and will include up to 260 participants. The doses participant get depends on the group they are (enrolled) in. All four groups will be receiving the investigational medicine for 15 weeks in total. Group A will start testing the dose level 1 (new tablet) for 5 weeks. Then receiving the current tablet of semaglutide C for 5 weeks and then testing the dose level 3 (new tablet) for 5 weeks. Group B will start receiving the current tablet semaglutide C for 5 weeks and then testing the dose level 2 (new tablet) in 5 weeks and dose level 4 (new tablet) in 5 weeks. Group C will start testing the dose level 1 (new tablet) and dose level 3 (new tablet) for 5 weeks each and then receiving the current tablet of semaglutide C (2x dose) for 5 weeks. Group D will start testing the dose level 2 (new tablet) for 5 weeks. Then receiving the current tablet of semaglutide C (2x dose) for 5 weeks and then testing the dose level 4 (new tablet) for 5 weeks. Participants will be receiving doses of semaglutide for 6 weeks before being assigned to one of the 4 groups (A-D) to reduce the risk of side effects. Participants cannot choose which group they want to be in, and they can only participate in one group in this study. Participant will get one tablet to be taken by mouth each day for approximately 21 weeks. The tablet should be taken in the morning together with no more than half a glass of water (120 milliliter [mL]), after an overnight fast of at least 6 hours (no food or drinks). Water is also not allowed from 2 hours before dosing. After dosing, participant must begin breakfast no earlier than 30 minutes and no later than 35 minutes after having taken tablet. The study will last for about 30 weeks in total for each participant. This includes a screening period (up to 4 weeks), a dose escalation period (6 weeks), an investigational treatment period (15 weeks) and a follow-up period (5 weeks after last dose). The planned duration a participant can receive trial product is 21 weeks. Participant should not take any prescription or non-prescription medicines (including herbal products) within 14 days prior to the screening visit (visit 1) and until the follow-up visit, except for birth control, routine vitamins, medicines applied on the skin, and occasional use of acetaminophen or ibuprofen (a mild pain killer). No oral medication (medicine taken by mouth) can be taken from 2 hours before and until 30 minutes after each dosing with semaglutide. Women cannot take part if pregnant, breast-feeding or planning to become pregnant during the study period.
The primary objectives of this study are to investigate the relative bioavailability and PK (Pharmacokinetic) profile of 2 ALXN2050 MR (Modified Release) formulations in comparison with the IR (Immediate Release) formulation.
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.
The main objective of this study is to assess pharmacokinetics, safety, and tolerability of ABBV-932 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.
Treatments for narcolepsy and hypersomnolence disorders should have good oral bioavailability and brain penetration properties. JZP441 has demonstrated wake-promoting efficacy and anticataplectic activity in nonclinical studies and may represent a novel approach for these patients.
