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 demonstrate that crizotinib (Arm A) is superior to first-line chemotherapy, pemetrexed/cisplatin or pemetrexed/carboplatin (Arm B), in prolonging PFS in patients with advanced non-squamous NSCLC whose tumors harbor a translocation or inversion…
1. Overall survival (primary efficacy endpoint)2a. Efficacy: progression-free survival (PFS), overall response rate (ORR = CR + PR), and a clincal benefit rate (CBR) will be evaluated as CR + PR + SD for at least 3 months.2b. Safety: adverse events…
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.
To investigate the effects of galantamine on cognitive impairment and visual hallucinations in Parkinson`s disease, both therapeutic (direct effect) and preventive (protection against an acute increase of dopaminergic medication used by the patient…
to assess whether a single-dose of levodopa improves cognitive symptoms and balances goal-directed and habitual behavior.
Primary objectives• To identify the percentage of patients in which a drug resistant clone can be detected with ctDNA before the emergence of radiological progression.• To determine the success rate of crizotinib and osimertinib combination…
The aim of this study is to improve our understanding of the mechanisms underlying altered social performance monitoring from a pharmacological perspective by directly comparing the effects of dopamine and oxytocin on individual and social…
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 determine the RP2D of crizotinib in combination with temsirolimus • To determine the safety and preliminary activity of single-agent crizotinib in ALK, MET or ROS1 positive tumors Secondary• To study the preliminary activity of…
This study will evaluate the efficacy and safety of entrectinib compared with crizotinib in patients who have NSCLC harboring ROS1 gene rearrangements with and without CNS metastases. Specific objectives and corresponding endpoints for the study are…
To demonstrate that lorlatinib as a single agent (Arm A) is superior to crizotinib alone (Arm B) in prolonging Progression-Free Survival (PFS) in advanced ALK-positive NSCLC participants who are treatment naive.
To investigate whether early treatment with levodopa has a delayed beneficial effect on PD symptoms and functional health, and improves the ability to (maintain) work, reduces the use of (informal) care, caregiver burden, and costs. Additionally,…
Primary objective* To study the antitumor activity and safety of crizotinib across predefined tumor types in patients whose tumors are harboring specific alterations in ALK and/or METSecondary objectives* To study the specificity of the kinase…
