SOUTH SAN FRANCISCO, Calif., Nov. 7, 2024 -- Lyell Immunopharma, Inc. (Nasdaq: LYEL), a clinical‑stage T‑cell reprogramming company advancing a diverse pipeline of cell therapies for patients with solid tumors or hematologic malignancies, today reported financial results and business highlights for the third quarter ended September 30, 2024.
“With our acquisition of ImmPACt now complete, we plan to accelerate the development of IMPt-314, a dual-targeting CD19/CD20 CAR t-cell product candidate we believe has the potential to deliver increased complete response rates with longer duration of response over approved CD19 CAR t-cell therapies for patients with aggressive B‑cell non‑Hodgkin’s lymphoma,” said Lynn Seely萬.D., Lyell’s President and CEO. 「We look forward to presenting the initial data from the Phase 1 trial of IMPt-314 at ASH next month and expect to initiate a pivotal clinical trial in 2025. In addition, site selection and initiation is progressing well for our Phase 1 trial of LYL119, our next-generation ROR1‑targeted CAR T‑cell product candidate designed with four technologies to generate t cells with even greater capacity to resist exhaustion. Our strong cash position enables us to advance our pipeline through important clinical milestones and fund operations into 2027.」
Third Quarter Updates and Recent Business Highlights
Lyell is advancing two wholly-owned product candidates: IMPt-314 is in Phase 1-2 clinical development and LYL119 is entering Phase 1 clinical development. Lyell is also advancing next-generation CAR t-cell product candidates for solid tumors, which are in preclinical development.
IMPt-314 – A next-generation dual-targeting CD19/CD20 CAR t-cell product candidate designed for improved response rates with enhanced durability for the treatment of large b-cell lymphoma (LBCL)
•LYL119是一種自體ROR1靶向CAR T細胞產品候選藥物,採用了四種新穎技術進行增強:c-Jun過表達,NR4A3缺失,Epi-R製造方案和Stim-R此款超便攜式投影儀使用了最新的 Android TV 界面,而且遙控器還內置了 Google AssistantTM 功能,用戶可以非常方便地使用它。 T細胞激活技術旨在使T細胞抵抗疲勞並增強其幹細胞樣特性。
•在2024年海豐國際年會上展示一份題爲「LYL119的多組學剖析: 重編程的ROR1 CAR t產品產生了具有降低疲勞和增強記憶特性的t細胞, 這些特性與增強的AP-1結合以及減少的NR4A結合相關」的海報。 在經過驗證的非小細胞肺癌異種移植模型中,與Lyell首代ROR1靶向CAR T細胞產品候選藥物LYL797相比,LYL119在非常低的劑量下實現了完全的腫瘤控制和延長生存時間。該研究闡述了在體外和體內抗原相遇後,LYL119 CAR t細胞的功能性疲勞減少和記憶相關特性增強的潛在分子機制。
