Background and Purpose— Granulocyte colony–stimulating factor (G-CSF; AX200; Filgrastim) is a stroke drug candidate with excellent preclinical evidence for efficacy. A previous phase IIa dose–escalation study suggested potential efficacy in humans. The present large phase IIb trial was powered to detect clinical efficacy in acute ischemic stroke patients. Methods— G-CSF (135 µg/kg body weight intravenous over 72 hours) was tested against placebo in 328 patients in a multinational, multicenter, randomized, and placebo-controlled trial (NCT00927836; www.clinicaltrial.gov). Main inclusion criteria were ⩽9-hour time window after stroke onset, infarct localization in the middle cerebral artery territory, baseline National Institutes of Health Stroke Scale score range of 6 to 22, and baseline diffusion-weighted imaging lesion size ≥15 mL. Primary and secondary end points were the modified Rankin scale score and the National Institutes of Health Stroke Scale score at day 90, respectively. Data were analyzed using a prespecified model that adjusted for age, National Institutes of Health Stroke Scale score at baseline, and initial infarct volume (diffusion-weighted imaging). Results— G-CSF treatment failed to meet the primary and secondary end points of the trial. For additional end points such as mortality, Barthel index, or infarct size at day 30, G-CSF did not show efficacy either. There was, however, a trend for reduced infarct growth in the G-CSF group. G-CSF showed the expected peripheral pharmacokinetic and pharmacodynamic profiles, with a strong increase in leukocytes and monocytes. In parallel, the cytokine profile showed a significant decrease of interleukin-1. Conclusions— G-CSF, a novel and promising drug candidate with a comprehensive preclinical and clinical package, did not provide any significant benefit with respect to either clinical outcome or imaging biomarkers.

Klinische und apparative Diagnostik

Lorenz Breuer; Rainer Kollmar; Martin Köhrmann

In Kurze: Patienten mit der Verdachtsdiagnose eines ischamischen oder hamorrhagischen Schlaganfalls sollten eine strukturierte Diagnostik, Therapie und Sekundarprophylaxe erhalten. Zur Bestatigung der Verdachtsdiagnose ist bereits vor Beginn der Therapie eine adaquate neuroradiologische Diagnostik notwendig. Im Allgemeinen reichen hierzu eine kraniale Computertomografie oder eine Kernspintomografie aus. Die Entscheidung uber eine erweiterte Diagnostik mittels Angiografie oder Perfusionsmessung ergibt sich aus der klinischen Symptomatik und dem CT oder MRT. Sollte eine initiale kausale Therapie mittels Thrombolyse moglich sein, wird diese sobald wie moglich begonnen. Spatestens bei Aufnahme auf die Stroke Unit sollte aber eine Basisdiagnostik mittels EKG und Routineblutabnahme beginnen. Selbstverstandlich gehort hierzu auch die Erfassung potentieller Risikofaktoren wie Nikotinabusus oder Hypercholesterinamie. Jeder Patient mit einem erstmaligen Schlaganfall sollte eine Ultraschalluntersuchung der hirnversorgenden Gefase erhalten. Im Weiteren sollte, je nach Alter und Vorerkrankungen, eine erweiterte kardiale Diagnostik mittels Echokardiografie und Langzeit-EKG durchgefuhrt werden. Insbesondere junge Patienten sollten auf Gerinnungsstorungen untersucht werden. Das folgende Kapitel stellt eine Ubersicht wesentlicher Untersuchungsmethoden und Befunde dar.
