  • Rechtszaak gericht tegen Lonza, producent van CASGEVY, 's werelds eerste goedgekeurde CRISPR-gebaseerde gentherapie
  • Tweede Europese rechtszaak, na het Verenigd Koninkrijk, ter bescherming van ToolGen's CRISPR-Cas9 RNP-technologie

SEOUL, Zuid-Korea, 8 september 2025 /PRNewswire/ --ToolGen, Inc. (KOSDAQ: 199800), wereldwijd toonaangevend in genoom­bewerkingstechnologie, heeft een octrooi-inbreukprocedure aangespannen tegen Lonza Netherlands B.V. De zaak is aanhangig gemaakt bij de rechtbank Den Haag.

Volgens ToolGen maakt Lonza, bij de productie van Vertex' CASGEVY in haar Nederlandse productielocatie, inbreuk op Europees octrooi EP 4 357 457. Dit octrooi stelt de CRISPR-Cas9 RNP-technologie onder bescherming, die intracellulaire toediening van Cas9-eiwit en gids-RNA in een geoptimaliseerde verhouding mogelijk maakt.

CASGEVY, ontwikkeld door Vertex Pharmaceuticals en CRISPR Therapeutics, is de eerste genbewerkingstherapie die is goedgekeurd voor de behandeling van sikkelcelziekte en bèta-thalassemie. CASGEVY is goedgekeurd in het Verenigd Koninkrijk, de Verenigde Staten en de Europese Unie. Lonza produceert CASGEVY in Nederland op basis van een lange termijn toeleveringsovereenkomst met Vertex.

Deze Nederlandse procedure volgt op een rechtszaak die ToolGen in april in het Verenigd Koninkrijk aanspande tegen partijen die betrokken zijn bij de productie en distributie van CASGEVY. Met de actie in Nederland wil ToolGen het belang van haar fundamentele CRISPR-Cas9 RNP-technologie onderstrepen en haar intellectuele eigendomsrechten in Europa krachtig beschermen.

"Het succes van CASGEVY is mede mogelijk gemaakt door de unieke CRISPR-Cas9 RNP-technologie van ToolGen," aldus Jong Sang Ryu, CEO van ToolGen. "Wij kunnen het ongeoorloofde gebruik van onze technologie niet accepteren en hebben daarom deze rechtszaak gestart. Deze procedure is er niet op gericht patiënten de toegang tot baanbrekende therapieën te ontzeggen, maar om eerlijke erkenning en passende compensatie te verkrijgen voor de waarde van onze innovaties. We staan open voor een minnelijke oplossing, waarmee een duurzaam en evenwichtig ecosysteem wordt bevorderd."
