Quantitative (pharmacodynamic) EEG\/ERP data analyses (e.g. power spectra, time-frequency analyses, source analyses) are conducted in Berlin. PI PharmaImage also developed a novel EEG monitoring system for safety assessment during\/after dosing\/dose escalation e.g. for early detection of seizure activity (e.g. with glutamatergic compounds) or toxic encephalopathy. While the PI PharmaImage EEG monitoring equipment can be located at any CRO\/hospital worldwide, the clinical EEG assessments are remotely conducted in real-time in Berlin by a certified clinical neurophysiologist (pharmaco-EEG expert). Safety monitoring data can be simultaneously used for pharmacodynamic measurements (e.g. surrogate outcome measures).<\/p>\n\n\n\n<p style=\"line-height:24px;font-size:14px;\">For more information see: <a href=\"https:\/\/pi-pharmaimage.com\/neuroimaging\/\">Imaging &amp; Electrophysiology Biomarkers<\/a><\/p>\n\n\n\n<div style=\"height:15px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-columns is-style-background-and-borders is-layout-flex wp-container-core-columns-is-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">Hardware<\/h2>\n\n\n\n<p style=\"font-size:14px\">The Pharmaimage hardware below can be delivered to the clinical study site (e.g. CRO):<\/p>\n\n\n\n<p style=\"font-size:14px\">Electrophysiological <br>investigations:<\/p>\n\n\n\n<ul style=\"font-size:14px\"><li> 4 complete EEG-recording BrainAmp DC 32-channel systems with 4 recording dongles, 4 laptops and 4 EasyCaps 32-channels<\/li><li>2 LED Photic-Light Stimulators with trigger box compatible to BrainAmp EEG recorders<\/li><\/ul>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">Endpoints \/ software standard packages:<\/h2>\n\n\n\n<p style=\"font-size:14px\">Electrophysiology endpoints:<\/p>\n\n\n\n<ul style=\"font-size:14px\"><li> EEG (resting state\/event-related): power spectra, coherence, time-frequency (e.g. gamma, theta oscillations, signal-to-noise ratio) incl. source analysis<\/li><li>ERPs: P50, N100, P300, MMN incl. source analysis<\/li><li>  Additionally requested parameters are possible<\/li><\/ul>\n\n\n\n<p style=\"font-size:14px\">Software: BrainVision Analyzer 2, BESA, sLORETA<\/p>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-group is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\" style=\"font-size:35px\">Electrophysiology<\/h2>\n\n\n\n<p style=\"font-size:14px\">Among functional biomarkers, electrophysiology (EEG) is the work horse in CNS drug research.

An additional advantage is that test-retest reliability is high and that center measurement effects are negligible in multicenter settings.

The system was tested in 2015 together with the CRO Hammersmith Medicines Research (HMR) in London (UK). To improve safety during clinical phase-I studies, the monitoring system was designed such that a highly sensitive assessment of SAEs affecting brain function such as epileptic seizures, diffuse encephalopathic (toxic) changes or strokes, which may lead to coma and death, is possible. When this kind of SAEs are detected early enough, further diagnostic and treatment intervention measures may prevent the worst case scenario. Accordingly, the PI PharmaImage monitoring system is particularly valuable when any drug, which affects brain function, is tested in clinical phase-I studies (first in human study) \u2013 most notably when dose escalation is conducted.<\/p>\n\n\n\n<p style=\"font-size:14px\">PI PharmaImage has established a real-time neurophysiological\/video monitoring system using a secure web-based remote monitoring system for electroencephalographic (EEG) and video data. A trained neurophysiologist in Berlin is able to analyse signals in real-time while data acquisition elsewhere (e.g. in London) is ongoing. The system does not require particular expertise on-site at the CRU wherever it is located. PI PharmaImage is providing and setting up the equipment for the duration of the study and also provides on-site training of staff and standard-operating procedures (SOPs). Using the neurophysiological safety monitoring data, additional sophisticated pharmacodynamic analyses (&#8220;surrogate endpoint analyses&#8221;) can also be conducted with the very same data set.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Hardware The Pharmaimage hardware below can be delivered to the clinical study site (e.g. CRO): Electrophysiological investigations: 4 complete EEG-recording BrainAmp DC 32-channel systems with 4 recording dongles, 4 laptops and 4 EasyCaps 32-channels 2 LED Photic-Light Stimulators with trigger box compatible to BrainAmp EEG recorders Endpoints \/ software standard packages: Electrophysiology endpoints: EEG (resting &hellip; <a href=\"https:\/\/pi-pharmaimage.com\/electrophysiology\/\">Continued<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":2,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/pages\/468"}],"collection":[{"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/comments?post=468"}],"version-history":[{"count":56,"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/pages\/468\/revisions"}],"predecessor-version":[{"id":1469,"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/pages\/468\/revisions\/1469"}],"wp:attachment":[{"href":"https:\/\/pi-pharmaimage.com\/wp-json\/wp\/v2\/media?parent=468"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
