To replicate and extend the findings of the recent methylphenidate study in which methylphenidate was found to enhance episodic memory performance; To explore whether this effect of methylphenidate is primarily mediated by its dopaminergic action.
This is a medical-scientific research study. The purpose of the study is to investigate the effect of multiple doses of the study compound BIA 28-6156 on the pharmacokinetics of the drugs levodopa-carbidopa (Group 1) and levodopa-benserazide (Group…
Primary:To demonstrate the non-inferior antiviral activity of switching to a two drug CAB LA 400 mg + RPV LA 600 mg regimen every 4 weeks compared to remaining on ABC/DTG/3TC (or DTG and an approved dual-NRTI scheme) over 48 weeks.Secondary:To…

to assess whether a single-dose of levodopa improves cognitive symptoms and balances goal-directed and habitual behavior.
The study consists of two phases. In the first phase, we aim to investigate whether the dopamine receptor D4 (DRD4) genotype confers differential susceptibility to the effects of early life stress on empathy and prosocial behavior more generally in…
To characterize the single-dose pharmacokinetic (PK) of RPV after SC administration of RPV LA suspensions with different doses and/or different particle size (PS) to support further dose and formulation selection, in healthy adult participants.To…
