Filter by:This is a single center, 2-Part, Phase 1, open-label, fixed-sequence, drug-drug interaction study designed to compare the PK of ecopipam when administered alone and in combination with itraconazole (Part 1) or rifampicin (Part 2) in healthy subjects.
Cannabidiol (CBD) is available as a prescription drug product for the treatment of seizures associated with Lennox-Gastaut syndrome, Dravet syndrome, or tuberous sclerosis complex. At labeled doses up to 25 mg/kg/day, an increased risk of liver enzyme elevation and drug-induced liver injury has been observed. However, only limited evaluations of the risk of liver enzyme elevation of daily, lower dose CBD use are available. The potential for liver enzyme elevations with lower CBD doses with unapproved consumer products highlights a need for further research. In addition, CBD has the capacity to inhibit cytochrome P450 enzymes and uridine 5'-diphospho-glucuronosyltransferases, leading to potential drug-drug interactions with multiple common medications. The clinical significance of many of these interactions is also unclear. Furthermore, nonclinical studies have suggested the potential for CBD to cause reproductive and endocrine effects. As such, additional high-quality clinical pharmacology studies are needed to further characterize CBD's safety profile. The objective of this study is to characterize the effects of daily CBD use at a dose within the range of what consumers are taking as unapproved CBD products on liver enzyme elevations, drug interactions, and endocrine measures.
The primary object of this study is evaluating the effect of multiple oral oseltamivir phosphate capsules on the pharmacokinetic profile of the active metabolite ZX-7101 after a single oral administration of ZX-7101A tablet in healthy Chinese adult subjects. The seongdary object is evaluating combined or uncombined multiple oral oseltamivir phosphate in healthy Chinese adult subjects.
A five-year prospective observational cohort study. The study is focused on observing the relation between static germline variants and therapeutic response in Indian children with acute lymphoblastic leukemia (ALL). The project is an International multicenter setup. This collaborative research project between Switzerland and India includes one main center in Geneva that has conceptualized, designed, received grants for the study and two investigating centers in India (Puducherry and New-Delhi) involved in study design, patient care and recruitment for this specific study. All the participants for the study will be recruited form these two centers in India, and no patient recruitment is planned at main center i.e. Geneva. The study will be conducted in two phases. The first aims to investigate genetic predisposition (static germline variants) to early chemotherapy treatment related toxicities (TRTs). The second aims to investigate somatic genetic markers associated with the efficacy of steroid treatment among patients undergoing the standardized IciCLe-ALL-14 treatment protocol. A total of 500 children with ALL will be recruited to investigate primary objective of the study i.e. TRT, and a subset of 250 patients will be included to investigate another research question i.e. response to steroid therapy.
This is a drug-drug interaction (DDI) study of mirtazapine for methamphetamine (MA) use disorder (MUD) to ensure the safety of this medication in the presence of a relevant dose of MA for people actively-using MA. Aim 1: To determine if mirtazapine alters the cardiovascular response to IV MA. Aim 2: To determine if the pharmacokinetics of IV MA are altered by mirtazapine administration. Aim 3: To evaluate the above aims in the setting of concomitant administration of methadone. This study involves two simultaneous within-subject drug-drug interaction studies, each comprised of 12 participants. A total of 24 subjects will be enrolled who have methamphetamine use disorder who will be classified into 2 groups: (Group 1: no opioids; Group 2: opioid use disorder on methadone maintenance). Subjects will be randomized to the order of mirtazapine and placebo (i.e. one-half will receive mirtazapine first, then placebo; one-half will receive placebo first, then mirtazapine).
There are currently no published studies addressing drug-drug interactions (DDI) between masculinizing hormone therapy (MHT) and pre-exposure prophylaxis (PrEP) among transgender men (TGM). This could lead to concerns and subsequent prioritizing MHT over PrEP among TGM. Because tenofovir alafenamide (TAF) can achieve higher intracellular tenofovir diphosphate (TFV-DP) levels with lower tenofovir plasma concentrations, it is promising that both plasma tenofovir (TFV) and intracellular TFV-DP levels might not be significantly affected by MHT. The current study aims to determine the pharmacokinetics (PK) DDI between MHT and daily PrEP among TGM.
