"Fast Track designation from the FDA reinforces our belief in the potential for LYT-200 to address the urgent needs of AML patients," said Luba Greenwood, J.D., Entrepreneur-in-Residence at PureTech who is leading the Gallop Oncology work. "This milestone builds on the FDA’s recognition of LYT-200’s promise, including Orphan Drug designation for AML and a second Fast Track designation for head and neck cancers, both of which were granted last year. By targeting galectin-9, a key driver of cancer proliferation and immune suppression, LYT-200 represents a novel and promising approach for patients in need, and we look forward to the continued development of this program."

LYT-200 exerts its therapeutic effects in AML by killing cancer cells directly via apoptosis and DNA damage as well as reactivating central anti-cancer effectors of the immune system. LYT-200 is the most advanced clinical program against galectin-9 and is being evaluated in two ongoing clinical trials, including:

1. Phase 1/2 clinical trial evaluating LYT-200 as a monotherapy and in combination with venetoclax and hypomethylating agents in hematological malignancies, including AML and high-risk myelodysplastic syndrome (MDS). In this trial, LYT-200 has demonstrated a favorable safety and tolerability profile as well as early signals of clinical activity as single agent and in combination.

2. Phase 1/2 trial in advanced/metastatic solid tumors, including head and neck

cancers. In this trial, LYT-200 is being evaluated as a monotherapy and in combination with tislelizumab, an anti-PD-1 antibody developed by BeiGene. To date, LYT-200 has demonstrated a favorable safety profile in all cohorts, including the monotherapy and combination arms with BeiGene’s tislelizumab, and shown disease control and suggestions of initial anti-tumor activity.

The FDA has also granted orphan drug designation to LYT-200 for the treatment of AML as well as a separate Fast Track designation for the treatment of recurrent/metastatic head and neck squamous cell carcinomas ("head and neck cancers"), in combination with anti-PD1 therapy. PureTech previously announced that it intends to advance LYT-200 via its Founded Entity, Gallop Oncology.

About LYT-200

LYT-200 is a fully human IgG4 monoclonal antibody targeting a foundational oncogenic and immunosuppressive protein, galectin-9, for the potential treatment of hematological malignancies and locally advanced metastatic solid tumors, including head and neck cancers, with otherwise poor survival rates. A wide variety of preclinical data support the potential clinical efficacy of LYT-200 and the importance of galectin-9 as a target and suggest a potential opportunity for biomarker development. PureTech has presented data demonstrating high expression of galectin-9 across various solid tumor types and blood cancers and has found that, in several cancers, galectin-9 levels correlate with shorter time to disease relapse and poor survival. Preclinical work also demonstrates single mechanistic and anti-tumor efficacy of LYT-200 in multiple animal and patient-derived tumor cell models. For example, LYT-200 outperforms anti-PD-1 in solid tumor models models as a single agent. LYT-200 also synergizes with anti-PD-1 in activating CD4 and CD8 T cells in in vivo cancer models. LYT-200 is currently being evaluated in two ongoing Phase 1/2 adaptive design trials for the potential treatment of AML/MDS and head and neck cancers.

The company expanded its pipeline in Q4 2024, by nominating two development candidates, one for its interleukin-18 (IL-18) program and one for its IL-12 program. MURA-8518 is designed to be a half-life extended, binding protein-resistant IL-18 in order to overcome the native cytokine’s limitations as a therapeutic. Mural expects to submit an Investigational New Drug (IND) Application or Clinical Trial Application (CTA) for a phase 1 trial of MURA-8518 in Q4 2025. MURA-7012 is comprised of targeted split IL-12 sub-units that preferentially self-assemble at the tumor site and are designed to limit systemic exposure.

"In just over a year since becoming an independent company, we have transformed Mural from a biotech with a binary readout expected in 2025 into a robust organization with multiple expected data catalysts. Not only have we stayed on track with our milestones as planned, we have also extended our cash runway into the first quarter of 2026 through operational efficiency," said Caroline Loew, Ph.D., CEO of Mural Oncology. "With two readouts in our late-stage trials on the horizon, nemvaleukin has the potential to become a new treatment option for patients with high unmet need in platinum-resistant ovarian cancer and mucosal melanoma. 2025 will be a pivotal year for Mural, and we look forward to advancing our clinical programs to bring value to patients and shareholders alike."

Upcoming catalysts:

Late Q1/early Q2 2025: Interim data readout of ARTISTRY-7, Mural’s potentially registrational phase 3 trial in PROC. The trial is evaluating nemvaleukin in combination with pembrolizumab versus investigator’s choice single agent chemotherapy. Consistent with Mural’s prior timing projections, the trial has now reached the 75% of OS events necessary for the planned interim analysis. The data will remain blinded to the company until after the independent data monitoring committee (IDMC) has reviewed the interim analysis, which is expected to be in late Q1/early Q2 2025. Consistent with interim analyses, there is a higher statistical bar for success at the interim analysis compared to the final analysis. If the hazard ratio meets this pre-specified higher bar for success at the interim analysis (0.727, or a 27.3% reduction in the risk of death assuming exactly 215 OS events), the company plans to submit a Biologics License Application (BLA) for nemvaleukin in combination with pembrolizumab for the treatment of PROC in 2025. If the hazard ratio does not meet the statistical threshold for success at the interim analysis and the company deems the study to have a high probability of success for the final analysis, Mural expects to continue the trial to the protocol-specified final OS analysis, where the maximum hazard ratio for success is 0.788, or a 21.2% reduction in the risk of death, assuming exactly 286 OS events. The company expects to report these final OS results in the second quarter of 2026, subject to event accrual.
Q2 2025: Top-line data readout of Cohort 2 of ARTISTRY-6, Mural’s potentially registrational phase 2 trial of nemvaleukin monotherapy in patients with unresectable or metastatic mucosal melanoma previously treated with immune checkpoint blockade. Nemvaleukin has been granted Orphan Drug Designation by the FDA for the treatment of mucosal melanoma. The target response rate in the ARTISTRY-6 trial is 25%. Mural believes that in this rare and highly aggressive tumor, which has historically had poor outcomes even in the first line setting, demonstrating durable responses with a response rate of 20-25% would be meaningful for patients, and would support a discussion with the FDA regarding a BLA submission and potential accelerated approval.
1H 2025: Preliminary data readout of Cohort 3 of ARTISTRY-6, an evaluation of a less-frequent intravenous (LFIV) dose of nemvaleukin monotherapy in patients with cutaneous melanoma. Patient enrollment in this cohort is now complete. If the data are promising, following subsequent clinical evaluation, LFIV dosing could offer a more convenient dosing regimen for patients and providers alike.
2H 2025: Preliminary data readout of Cohort 4 of ARTISTRY-6, an evaluation of a LFIV dose of nemvaleukin in combination with pembrolizumab in patients with cutaneous melanoma.
Q4 2025: Mural expects to submit an IND or CTA for a phase 1 trial of MURA-8518, its IL-18 development candidate.

Lyell to Highlight Vision for its Next-Generation CAR T-Cell Therapy Pipeline at 43rd Annual JP Morgan Healthcare Conference

On January 9, 2025 Lyell Immunopharma, Inc. (Nasdaq: LYEL), a clinical-stage company advancing a pipeline of next-generation CAR T-cell therapies for patients with cancer, reported pipeline updates, including its plans to advance IMPT-314, a potentially best-in-class therapy for aggressive large B-cell lymphoma, into pivotal trials (Press release, Lyell Immunopharma, JAN 9, 2025, View Source [SID1234649542]). IMPT-314 is an autologous dual-targeting CD19/CD20 chimeric antigen receptor (CAR) T-cell product candidate designed to increase complete response rates and prolong the duration of the responses as compared to the approved CD19‑targeted CAR therapies for the treatment of large B-cell lymphoma.

"Based on the positive initial clinical data reported at ASH (Free ASH Whitepaper) and the promising emerging clinical profile, we are accelerating the development of IMPT-314 as a potentially transformative product with differentiated benefit in overall and complete response rates as well as duration of response over first-generation CD19 CAR therapies in patients with aggressive large B-cell lymphoma," said Lynn Seely, M.D., Lyell’s President and Chief Executive Officer. "Having presented an initial dataset that demonstrated an overall response rate of 94% and a complete response rate of 71% in patients treated in the 3rd-line+ setting, we are focusing our resources on advancing IMPT-314 for patients with large B-cell lymphoma in both the 2nd and 3rd line+ settings. To ensure a sustainable cost structure that delivers multiple clinical readouts with our current balance sheet, we have streamlined and focused our pipeline and organization to prioritize investment in IMPT-314 and early-stage research programs for solid tumors."

Pipeline Focus

Lyell is focused on advancing next-generation CAR T cell therapies with the potential to deliver higher response rates and longer duration of responses for patients with hematologic malignancies and solid tumors. Lyell is developing products enhanced with its novel technologies and manufacturing protocols.

In hematologic malignancies, Lyell is focused on advancing products designed to deliver improved outcomes over first-generation CD19 CAR T cell therapies. Lyell’s lead program, IMPT-314, is a dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of the responses as compared to the currently approved CD19‑targeted CAR therapies for the treatment of large B-cell lymphoma. IMPT-314 is designed with a true ‘OR’ logic gate to target B-cells that express either CD19, CD20 or both and is manufactured through a process that enriches for CD62L-expressing cells to generate more naïve central memory CAR T cells with enhanced stemlike features and antitumor activity.

To realize the potential of cell therapy for solid tumors, Lyell is also developing next-generation CAR T-cell product candidates enhanced with anti-exhaustion and additional arming technologies, and manufactured with proprietary protocols. These approaches are designed to endow CAR T cells with attributes needed to drive durable tumor cytotoxicity and achieve consistent and long-lasting clinical responses – the ability to resist exhaustion, maintain qualities of durable stemness and function in the hostile tumor microenvironment.

Upcoming Milestones and Financial Outlook

For IMPT-314, a next-generation dual-targeting CD19/CD20 CAR T-cell product candidate for the treatment of large B-cell lymphoma:

Present data from the ongoing Phase 1-2 trial in mid-2025, including more mature data from the 3rd line+ cohort and initial data from the 2nd line cohort
Present more mature clinical data from the 2nd line cohort in late 2025
Initiate a pivotal trial in the 3rd line+ setting in mid-2025
Initiate a pivotal trial in the 2nd line setting by early 2026
For early-stage solid tumor programs:

Submit first IND application for a new solid tumor CAR T-cell product candidate in 2026
To accelerate the pivotal trials of IMPT-314 and focus resources on next-generation solid tumor CAR T-cell programs in preclinical development, Lyell has streamlined its operations and is discontinuing development of LYL119, its ROR1-targeting CAR T cell product candidate, and IMPT-514, an autoimmune disease program previously initiated by ImmPACT Bio that was acquired by Lyell in connection with its acquisition of ImmPACT Bio.

Lyell expects net cash use in 2025 to be $175 million – $185 million, which extends its cash runway further into 2027 through multiple clinical milestones.

J.P. Morgan Healthcare Conference

Members of Lyell’s senior management team will present and participate in the 43rd Annual J.P. Morgan Healthcare Conference on Wednesday, January 15th at 9:00 am PT.

A live webcast of the presentation can be accessed through the Investors section of the Company’s website at www.lyell.com. Following the live presentation, a replay of the webcast will be available on the Company’s website.

About IMPT-314

IMPT-314 is a next-generation dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of the responses as compared to the approved CD19‑targeted CAR therapies for the treatment of large B-cell lymphoma.

IMPT-314 is designed with a true ‘OR’ logic gate to target, with high potency, B cells that express either CD19, CD20 or both. IMPT-314 is manufactured to produce a CAR T-cell product with higher proportions of naïve and central memory T cells through a process that enriches for CD62L-expressing cells. This manufacturing process is designed to generate more naïve central memory CAR T cells with enhanced stemlike features and antitumor activity.

IMPT-314 has received Fast Track Designation from the U.S. Food and Drug Administration for the treatment of relapsed/refractory aggressive B-cell lymphoma.

Initial data from 23 patients with relapsed or refractory, CAR T-naive large B-cell lymphoma who received IMPT-314 were reported at the 2024 American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting. The efficacy evaluable population consisted of 17 patients. The overall response rate was 94% (16/17 patients), with 71% (12/17 patients) achieving a complete response by three months. The median follow up was 6.3 months (range 1.2 – 12.5 months) and 71% of patients were in response at last follow-up. In the safety evaluable population of 23 patients, no Grade 3+ CRS was reported. Grade 3 ICANS was reported in 13% (3/23) of patients with a median time to complete ICANS resolution of 5 days, and rapid improvement to Grade 2 or lower with standard therapy.
