"There remains a high unmet medical need for patients with R/R acute myeloid leukemia with KMT2Ar or NPM1m for targeted therapies that yield robust response rates and durable response that are well tolerated," said Jatin Shah, M.D., Chief Medical Officer, Oncology, SMPA. "In addition, new classes of therapeutics and combination strategies to potentially improve upon the activity of JAK inhibitors are important in MF. With this in mind, we look forward to sharing encouraging new data that further support the therapeutic potential and development of our late-stage oncology pipeline at ASH (Free ASH Whitepaper)."

For enzomenib, the oral presentation will report efficacy and safety data from the pivotal Phase 2 arm of the Horizen-1 study in patients with R/R KMT2A rearrangements (KMT2Ar) AL. The data will highlight the therapeutic potential of enzomenib as a targeted treatment option for patients with this high-risk subset of AL.

Additionally, a poster presentation will include clinical findings from the completed dose optimization study of enzomenib that informed the recommended Phase 2 dose (RP2D) in patients with R/R AL with NPM1 mutation (NPM1m). The data demonstrated that both 200 mg twice a day (BID) and 300 mg BID of enzomenib were generally well tolerated with measurable clinical activity. Objective response rates (ORRs) were 54% and 57% in patients receiving 200 and 300 mg BID, respectively, while the complete remission and complete remission with partial hematologic recovery (CR+CRh) rates were 35% at 200 mg BID and 43% at 300 mg BID.

For nuvisertib, the oral presentation will report preliminary findings from the ongoing global Phase 1 dose escalation study evaluating nuvisertib and MMB in patients with MF previously treated with a JAK inhibitor show the combination appeared to be well tolerated in the dose levels evaluated. Promising clinical activity included symptom and spleen responses, anemia improvement, and cytokine modulation. These emerging clinical data support the Phase 3 clinical development of nuvisertib in combination with MMB for patients with MF and anemia.

About Enzomenib (DSP-5336)
Enzomenib is an investigational, oral, small molecule inhibitor of the menin and lysine (K)-specific methyltransferase 2A (KMT2A) protein interaction, a key interaction in acute leukemia and other tumor cell proliferation and growth.1 Menin is a scaffold nuclear protein that plays key roles in gene expression and protein interactions involved in many biological pathways, including cell growth, cell cycle, genomic stability, and hematopoiesis.2,3 In preclinical studies, enzomenib has shown selective growth inhibition in human acute leukemia cell lines with KMT2A rearrangements or NPM1 mutations.4 Enzomenib reduced the expression of the leukemia-associated genes HOXA9 and MEIS1 and increased the expression of the differentiation gene CD11b in human acute leukemia cell lines with KMT2A rearrangements or NPM1 mutations.1,4 The safety and efficacy of enzomenib are currently being clinically evaluated in a Phase 1/2 dose-escalation/dose-expansion study in patients with relapsed or refractory acute leukemia (NCT04988555) and the registrational Phase 2 Horizen-1 R/R mono AML/ALL (KMT2Ar + NPM1m) study. The FDA granted Orphan Drug Designation for enzomenib for the indication of acute myeloid leukemia in June 2022 and the indication of acute lymphoblastic leukemia in July 2026. The FDA granted Fast Track Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with KMT2Ar or NPM1m in June 2024 and Breakthrough Therapy Designation for the treatment of patients with relapsed/refractory acute leukemia with KMT2Ar in October 2026. Japan’s Ministry of Health, Labour and Welfare (MHLW) granted Orphan Drug Designation for enzomenib for the indication of relapsed or refractory acute myeloid leukemia with KMT2Ar or NPM1m in September 2024.

About Nuvisertib (TP-3654)
Nuvisertib is an oral investigational selective inhibitor of PIM1 kinase with added ACVR1 inhibition, which has shown potential antitumor and antifibrotic activity through multiple pathways, including induction of apoptosis in preclinical models.5-7 Nuvisertib was observed to inhibit proliferation and increase apoptosis in murine and human hematopoietic cells expressing the clinically relevant JAK2 V617F mutation.6 Nuvisertib alone and in combination with ruxolitinib showed reduction of spleen size and bone marrow fibrosis in JAK2 V617F and MPLW515L murine models of myelofibrosis.6 In addition to its primary activity against PIM1, nuvisertib has been shown to bind and inhibit ACVR1 in preclinical studies, which may contribute to hemoglobin responses in patients with myelofibrosis.7 The safety and efficacy of nuvisertib monotherapy or in combination with a JAK inhibitor are currently being clinically evaluated in a Phase 1/2 study in patients with intermediate- and high-risk myelofibrosis (NCT04176198). The FDA granted Orphan Drug Designation to nuvisertib for the indication of myelofibrosis in May 2022. The Japan Ministry of Health, Labour and Welfare (MHLW) granted Orphan Drug Designation to nuvisertib for the treatment of myelofibrosis in November 2024. The European Medicines Agency (EMA) granted Orphan Drug Designation to nuvisertib for the treatment of myelofibrosis in July 2025. The FDA granted Fast Track Designation to nuvisertib for the indication of myelofibrosis in June 2025.

About ARV-393 (zaloblideg)
Zaloblideg is an investigational, orally bioavailable PROTAC designed to specifically target and degrade B-cell lymphoma 6 protein (BCL6), a transcriptional repressor and major driver of B-cell lymphomas. During B-cell development, tightly controlled BCL6 protein expression regulates >600 genes to facilitate rapid B-cell proliferation and tolerance of somatic hypermutation and gene recombination for antibody generation. Deregulated BCL6 expression is common in B-cell lymphoma and promotes cancer cell survival, proliferation, and genomic instability. PROTAC-mediated degradation has the potential to address the historically undruggable nature of BCL6. ARV-393 (zaloblideg) is currently being evaluated in a Phase 1 clinical trial as a monotherapy in patients with relapsed/refractory non-Hodgkin lymphoma and in in combination with glofitamab as a chemotherapy-free combination approach in patients with DLBCL.

"The updated ronde-cel data accepted for presentation at ASH (Free ASH Whitepaper) further strengthen our conviction in ronde-cel’s potential to meaningfully improve outcomes for patients with large B-cell lymphoma," said Lynn Seely, M.D., President and Chief Executive Officer of Lyell. "The high rates of very durable complete responses achieved by ronde-cel in both the second- and third- or later-line settings, including in patients with high-risk primary refractory disease, clearly showcase the next-generation potential of ronde-cel. With two pivotal trials underway, including our single-arm pivotal PiNACLE trial expected to complete enrollment by year end and on track for pivotal data and BLA submission in the second half of 2027, we are now focusing on preparation for commercialization. We are also continuing to advance LYL273 following the successful transfer of manufacturing to LyFE, as we work to determine the recommended Phase 2 dose and optimize the safety management plan ahead of our planned End-of-Phase 1 discussions with the FDA in 2027."

Third Quarter Updates and Recent Business Highlights

Rondecabtagene Autoleucel (ronde-cel): A next-generation dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of response as compared to approved CD19‑targeted CAR T-cell therapies for the treatment of relapsed/refractory large B-cell lymphoma

Ronde-cel is an autologous CAR T-cell product candidate under evaluation in two pivotal trials in patients with relapsed/refractory (R/R) large B-cell lymphoma (LBCL) in the third- or later-line (3L+) setting (PiNACLE) and the second-line (2L) setting (PiNACLE‑H2H). A multi-cohort dose-escalation, dose-expansion Phase 1/2 trial is also ongoing. Ronde-cel targets B cells that express either CD19 or CD20 with a true ‘OR’ logic gate to achieve full potency at either target and is manufactured with a process that enriches for CD62L-positive cells to generate more naïve and central memory CAR T cells with enhanced stemlike features and antitumor activity. The U.S. Food and Drug Administration (FDA) has granted ronde-cel Regenerative Medicine Advanced Therapy (RMAT) and Fast Track designations for the treatment of adults with R/R diffuse LBCL in the 3L+ setting and also RMAT designation for the treatment of LBCL in the 2L setting.

Lyell announced today updated clinical data from the ongoing PiNACLE pivotal trial in patients with 3L+ R/R LBCL and from the Phase 1/2 trial 2L cohort of ronde-cel in patients with R/R LBCL in two abstracts accepted for presentation at the 68th American Society of Hematology (ASH) (Free ASH Whitepaper) Meeting and Exposition (ASH 2026), taking place December 12–15, 2026.
The PiNACLE pivotal single-arm trial, a seamless expansion of the 3L+ cohort in the Phase 1/2 multi-cohort trial, is ongoing. Pivotal data are expected in mid-2027 with submission of a Biologics License Application (BLA) to the FDA expected to follow in the second half of 2027. The primary endpoint of the trial is overall response rate, including an evaluation of duration of response.
PiNACLE-H2H, the first-of-its-kind Phase 3 randomized controlled trial evaluating ronde-cel versus investigator’s choice of axicabtagene ciloleucel or lisocabtagene maraleucel in patients with R/R LBCL in the 2L setting, continues to enroll patients. The trial’s primary endpoint is event-free survival.
LYL273: A next-generation guanylyl cyclase C (GCC)-targeted CAR T-cell product candidate for the treatment of relapsed/refractory metastatic colorectal cancer (mCRC) and other GCC-expressing cancers

LYL273 is a GCC-targeted CAR T-cell product candidate enhanced with CD19 CAR expression and controlled cytokine release, designed to improve CAR T-cell expansion, immune cell infiltration and cancer cell killing in the hostile solid tumor microenvironment. The FDA granted LYL273 Fast Track designation for the treatment of mCRC.

In September 2026, Lyell completed the planned technology transfer for LYL273 to its LyFE Manufacturing Center (LyFE) in Bothell, Washington, following FDA review of an improved manufacturing process and updated analytical methods. LyFE is implementing the improved manufacturing process and updated analytical methods to enhance manufacturing performance and increase capacity. The Phase 1/2 clinical trial of LYL273 in patients with R/R mCRC continues to enroll patients, including dosing of patients with LYL273 manufactured using the new process at LyFE, with the goal of determining the recommended Phase 2 dose and optimizing the safety management plan.
Additional clinical data from the Phase 1/2 trial of LYL273 in patients with 3L+ R/R mCRC and an End-of-Phase 1 meeting with the FDA are expected in 2027.
Corporate Update

In November 2026, the Company announced a private placement of $80.0 million with participation from a high-quality syndicate of existing and new investors. The proceeds are expected to extend cash runway into 2028, beyond anticipated BLA submission for ronde-cel in the second half of 2027, as well as updated clinical data from the GCC-targeted LYL273 program for patients with mCRC.
Third Quarter 2026 Financial Results

Lyell reported a net loss of $45.5 million for the third quarter ended September 30, 2026, compared to a net loss of $38.8 million for the same period in 2025. The $6.7 million increase in net loss was primarily due to a $12.7 million increase in research and development expenses driven by increased clinical trial activity, partially offset by a $4.0 million prior-year loss on the securities purchase agreement put/call that did not recur. Non‑GAAP net loss, which excludes non-cash stock-based compensation, non-cash expenses related to the change in the estimated fair value of the securities purchase agreement put/call relating to the Company’s July 2025 private placement transaction and success payment liabilities, increased by $12.2 million to $41.3 million for the third quarter ended September 30, 2026, compared to $29.1 million for the same period in 2025, primarily due to increased clinical trial activity and lower interest income.

GAAP and Non-GAAP Operating Expenses

Research and development (R&D) expenses were $40.9 million for the third quarter ended September 30, 2026, compared to $28.2 million for the same period in 2025. The $12.7 million increase was primarily due to a $12.2 million increase in research activities, collaborations and outside services due to increased clinical trial activity. Non‑GAAP R&D expenses, which exclude non-cash stock-based compensation, for the third quarter ended September 30, 2026 were $38.8 million compared to $26.2 million for the same period in 2025.
General and administrative (G&A) expenses were $9.3 million for the third quarter ended September 30, 2026, compared to $10.7 million for the same period in 2025, primarily due to lower professional services expenses. Non‑GAAP G&A expenses, which exclude non-cash stock‑based compensation, for the third quarter ended September 30, 2026 were $6.9 million compared to $7.5 million for the same period in 2025.
A discussion of non-GAAP financial measures, including reconciliations of the most comparable U.S. generally accepted accounting principles (GAAP) measures to non‑GAAP financial measures, is presented below under "Non-GAAP Financial Measures."

Cash, cash equivalents and marketable securities

Cash, cash equivalents and marketable securities as of September 30, 2026 were $194.0 million compared to $247.2 million as of December 31, 2025. Lyell believes that its current cash, cash equivalents and marketable securities balances, together with the net proceeds from the $80.0 million private placement in November 2026, will be sufficient to meet working capital and capital expenditure needs into 2028.
