The Company now has exclusive rights to a Malaysia, US and China patent
SINGAPORE, Jan. 29, 2024 (GLOBE NEWSWIRE) -- CytoMed Therapeutics Limited (NASDAQ: GDTC) ("CytoMed" or "Company"), a Singapore-based biopharmaceutical company focused on harnessing its proprietary technologies to develop novel donor-derived cell-based immunotherapies for the treatment of various cancers, announced today that the Intellectual Property Corporation of Malaysia has granted a patent for its chimeric antigen receptor gamma delta T cell ("CAR-γδ T cell") technology, which targets solid and hematological tumors.
The patent titled "Gamma Delta T Cells and a Method of Augmenting the Tumoricidal Activity of the Same" (Patent number: MY-200528-A) covers technologies for the clinical-scale expansion of γδ T cells from a small amount of donor peripheral blood cells, as well as the modification of the expanded γδ T cells to incorporate a chimeric antigen receptor ("CAR") that enables the modified cells to recognize a wide range of cancers, including both solid and hematological cancers. The Company holds an exclusive, worldwide license to use this patent pursuant to the License Agreement dated June 1, 2018, filed with the Securities and Exchange Commission as an exhibit to the registration statement on Form F-1 (File No.: 333-268456) on March 30, 2023.
"With the commencement of our first in-human clinical trial for CAR-γδ T cells in Singapore, we are pleased that our technology is granted a patent in Malaysia where our operational PIC/S GMP facility is situated," said Peter Choo, Chairman of CytoMed. "This grant adds to the breadth of our tumor-targeting therapy patent portfolio, alongside a US patent and Chinese patent in respect of this CAR T technology. This patent grant is timely as Malaysia is attracting more biomedical innovators amidst an ageing population and reputation as a medical tourism hub."
CytoMed's CAR-γδ T cell technology has been developed as an investigational cancer therapy to target NKG2D ligands, a type of stress-induced cancer antigens. The risk of "on-target-off-cancer" side effects may be reduced by targeting stress-induced antigens that are mainly expressed on cancer cells such as NKG2D ligands. The allogeneic CAR-γδ T cells for the clinical trial will be manufactured from donor blood and will be processed in CytoMed's current PIC/S Good Manufacturing Practice (GMP) facility in Malaysia.
The Company's patent portfolio also includes an exclusively licensed technology which covers an induced pluripotent stem cell (iPSC)-based technology to derive novel synthetic hybrid gamma delta natural killer T cells (γδ NKT cells) for the treatment of various types of cancers. A patent for this proprietary technology has been granted in Japan and China, and this asset is under preclinical development.
As a separate update, the Company has on January 12, 2024 submitted a drug master file to the US Food and Drug Administration in preparation for an investigational new drug filing to treat hematological and solid cancers using our allogeneic γδ T cells.
該公司現在擁有馬來西亞、美國和中國專利的專有權
新加坡,2024年1月29日(GLOBE NEWSWIRE)——總部位於新加坡的生物製藥公司CytoMed Therapeutics Limited(納斯達克股票代碼:GDTC)(“CytoMed” 或 “公司”)今天宣佈,馬來西亞知識產權公司已授予其嵌合療法的專利,該公司專注於利用其專有技術開發用於治療各種癌症的新型供體衍生細胞免疫療法。抗原受體 gamma delta T 細胞(“CAR-γT 細胞”)技術,靶向實體腫瘤和血液學腫瘤。
這項名爲 “伽瑪三角洲T細胞和增強其殺腫活性的方法” 的專利(專利號:MY-200528-A)涵蓋了從少量供體外周血細胞中擴增γ-β T細胞的臨床規模技術,以及改造擴大的γT細胞以納入使改性細胞能夠識別各種癌症的嵌合抗原受體(“CAR”)的技術,包括實體癌和血液癌。根據2018年6月1日的許可協議,公司擁有使用該專利的全球獨家許可,該協議於2023年3月30日作爲F-1表格(文件編號:333-268456)註冊聲明的附錄提交給美國證券交易委員會。
CytoMed董事長Peter Choo表示:“隨着我們在新加坡啓動了首個CAR-γ△T細胞人體臨床試驗,我們很高興我們的技術在馬來西亞獲得了專利,而馬來西亞的PIC/S GMP設施正位於馬來西亞。”“這筆撥款增加了我們腫瘤靶向療法專利組合的廣度,此外還有一項與這種CAR T技術相關的美國專利和中國專利。這項專利授予是及時的,因爲在人口老齡化和醫療旅遊中心的聲譽下,馬來西亞吸引了更多的生物醫學創新者。”
CytoMed 的 CAR-γT 細胞技術是作爲一種研究性癌症療法開發的,旨在靶向 NKG2D 配體,一種壓力誘導的癌症抗原。通過靶向主要在 NKG2D 配體等癌細胞上表達的壓力誘導抗原,可以降低 “非靶向癌症” 副作用的風險。用於臨床試驗的同種異體CAR-γ△T細胞將由供體血液製成,並將在CytoMed目前位於馬來西亞的PIC/S良好生產規範(GMP)工廠進行加工。
該公司的專利組合還包括一項獨家許可的技術,該技術涵蓋一種基於誘導多能幹細胞(iPSC)的技術,該技術旨在衍生出用於治療各種類型癌症的新型合成雜交伽瑪三角洲自然殺傷性T細胞(γβ NKT細胞)。這項專有技術的專利已在日本和中國獲得批准,該資產正在臨床前開發中。
作爲另一項更新,該公司已於2024年1月12日向美國食品藥品監督管理局提交了藥物主文件,爲使用我們的異基因γT細胞治療血液癌和實體癌的研究性新藥申請做準備。
