Descrizione riassuntiva della sperimentazione (Fonte di dati: BASEC)
Der Zweck dieser klinischen Studie ist, die positiven und negativen Wirkungen von Ranibizumab, das aus einem Augenimplantat (auch bekannt als Port Delivery System mit Ranibizumab oder PDS) verabreicht wird, bei Patienten mit nAMD zu beurteilen. In dieser klinischen Studie wird Ihnen ein Augenimplantat eingesetzt, das mit einer Dosis von 2 mg Ranibizumab gefüllt ist, die langsam durch das Implantat freigesetzt wird. Das Augenimplantat wird entweder alle 6 Monate oder alle 9 Monate mit Ranibizumab nachgefüllt. Das Augenimplantat gibt Ranibizumab kontinuierlich (ohne Unterbrechung) über einen langen Zeitraum in den Augenhintergrund ab und kann von Ihrem Studienarzt nachgefüllt werden.
Diese internationale klinische Studie soll in ca.16 Ländern weltweit durchgeführt werden. Die Studie dauert etwa 3 Jahre. In der Schweiz ist geplant, etwa 20 Personen in insgesamt 5 Studienzentren in die Studie einschließen zu können. Weltweit sollen voraussichtlich ca. 450 Personen in ungefähr 120 Studienzentren an der klinischen Studie teilnehmen.
Das aus dem Augenimplantat verabreichte Ranibizumab gilt als Studienpräparat (experimentelles Medikament), das Patienten nur im Rahmen klinischer Studien verabreicht wird. Der Wirkstoff Ranibizumab ist jedoch derselbe wie in dem von der Schweizerischen Gesundheitsbehörde Swissmedic zugelassenen Medikament Lucentis®. Das Augenimplantat ist ein experimentelles Medizinprodukt und von der Swissmedic nicht zur Implantation in das Auge zur nAMD-Behandlung zugelassen. Das Implantat hat ungefähr die Größe eines Reiskorns. Das Augenimplantat wird von der dünnen, durchsichtigen Bindehaut (Konjunktiva) des Auges bedeckt und ist normalerweise für andere nicht sichtbar, da es vom Oberlid verdeckt wird.

Criteri per la partecipazione alla sperimentazione
(Fonte di dati: BASEC)
Die Patienten müssen verschiedene Einschlusskriterien für das Studienauge bei Studieneintritt erfüllen. Nachfolgend sind die drei wichtigsten Einschlusskriterien gelistet, weitere Einschlusskriterien sind im Studienprotokoll enthalten:
· nAMD (= Neovaskuläre altersbedingte Makuladegeneration) Erstdiagnose innerhalb von 9 Monaten vor der Screening-Visite
· Vorangegangene nAMD Behandlung mit mindestens drei intravitrealen (= In den Glaskörper hinein) Anti-VEGF-Injektionen (z. B. Ranibizumab, Bevacizumab, Aflibercept) gemäß dem Therapiestandard innerhalb von 6 Monaten vor der Screening-Visite (VEGF = Vascular endothelial growth factor = Gruppe von Proteinen, die als Signalmoleküle unterschiedliche Aufgaben erfüllen). Wenn ein Patient nicht mindestens drei Anti-VEGF-Injektionen wie oben beschrieben erhalten hat, aber ansonsten für die Studie in Frage kommt, kann der Patient in einer Run-in-Phase vor dem Screening behandelt werden, um dieses spezifische Kriterium zu erfüllen.
· Es zeigte sich ein Ansprechen auf eine vorangegangene intravitreale Anti-VEGF-Behandlung seit der Diagnosestellung, welches durch verschiedene Kriterien belegt wird (Kriterien im Studienprotokoll enthalten)
Criteri di esclusione

Patienten, die verschiedene Ausschlusskriterien erfüllen, werden von der Studienteilnahme ausgeschlossen. Nachfolgend sind die drei wichtigsten Ausschlusskriterien gelistet, weitere Ausschlusskriterien und Beispiele sind im Studienprotokoll enthalten:
