"While CAR T therapies have been effective for blood cancers, solid tumors like lung and colorectal cancers have proven to be resistant to current CAR T therapies", said Jeff Liter, CEO and President of Luminary Therapeutics. "This project combines an allogeneic CAR T for direct killing of tumor cells with the ability to utilize the patient’s immune system to target tumor cells by also leveraging the gamma delta cell’s ability to work as professional antigen-presenting cells (APCs) and presenting tumor-specific neo antigens. Combining neo antigen-presenting functions with CAR directed killing in a single cellular chassis will increase the effectiveness of cellular therapies by recruiting a patient’s immune system to increase the response and durability of tumor clearance."

Since its founding in 2019, Luminary Therapeutics has developed a proprietary gamma delta expansion platform that is unique in the industry and allows Luminary to manufacture cell therapies with a significantly lower cost and reduced time to clinic. Leveraging this platform, the Company has developed two groundbreaking therapeutic programs designed to overcome current challenges of CAR T therapies for solid tumors and autoimmune disorders. The award from ARPA-H represents not only a significant step forward in scaling Luminary’s therapeutic pipeline, while expanding the capabilities of its gamma delta expansion platform, but also aligns with ARPA-H’s mission to improve health outcomes for everyone.

Actinium Pharmaceuticals Announces Initiation of Actimab-A Triplet Combination Frontline Trial Under NCI CRADA with Venetoclax and Taiho Oncology’s Hypomethylating Agent ASTX-727 in Patients with Newly Diagnosed AML

On March 11, 2025 Actinium Pharmaceuticals, Inc. (NYSE AMERICAN: ATNM) (Actinium or the Company), a pioneer in the development of targeted radiotherapies, reported that the first clinical trial under its previously announced Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI) for Actimab-A has been initiated (Press release, Actinium Pharmaceuticals, MAR 11, 2025, View Source [SID1234651081]). The trial (NCT06802523) will evaluate the triplet combination comprised of Actimab-A, Venetoclax (Abbvie/Roche) an oral Bcl-2 inhibitor and ASTX-727 (Taiho Oncology, an Otsuka holdings company) a novel oral hypomethylating agent (HMA) in frontline acute myeloid leukemia (AML) patients. Venetoclax in combination with HMAs (Ven-HMA) is approved for patients with newly diagnosed AML. Actimab-A, a humanized anti-CD33 antibody conjugated to Actinium-225 (Ac-225) targets CD33, a marker expressed ubiquitously on myeloid blasts in patients with AML and other hematologic malignancies. The potent alpha-particle payload Ac-225 causes lethal double strand DNA breaks for which there are no known resistance or repair mechanisms. This study will evaluate the rate and duration of Complete Remission (CR), as well as safety, including the optimal dose of Actimab-A in combination with Venetoclax and ASTX-727 for potential future studies.

Dr. Avinash Desai, Actinium’s Chief Medical Officer, commented, "We are incredibly excited that the first Actimab-A trial initiated under our CRADA with the NCI is this triplet combination with Venetoclax and Taiho’s ASTX-727. While Ven-HMA has positively impacted outcomes in AML, a significant number of patients have poor responses or relapse quickly resulting in dismal outcomes. We believe Actimab-A’s potentially synergistic, and mutation agnostic mechanism of action can improve clinical outcomes for these patients by producing deeper remissions, including measurable residual disease negativity, that are more durable. Due to its mutation agnostic mechanism, Actimab-A can overcome high-risk features, such as TP53 mutations, and has demonstrated the ability to improve outcomes in these patients where Ven-HMA has had limited success. This triplet regimen can be conveniently administered in the outpatient setting as Venetoclax and ASTX-727 are both oral agents and Actimab-A does not require isolation given that it is an alpha-particle emitter. We are eager to collaborate with NCI on this important study to evaluate earlier intervention with a CD33 targeted radiotherapy in patients with AML."

Actimab-A in combination with Venetoclax was previously studied in a multi-center Phase 1 trial. The combination was shown to be well tolerated with manageable adverse events. Preclinical studies showed that Actimab-A can synergize with Venetoclax by depleting MCL-1, which mediates Venetoclax resistance.

Sandesh Seth, Actinium’s Chairman & CEO, said, "We believe 2025 will be a transformational year for Actimab-A and that the initiation of this triplet trial is a significant catalyst. It is our objective to establish Actimab-A as a backbone therapy across the treatment continuum of AML and other myeloid malignancies leveraging the broad expression of CD33 and the mutation agnostic Ac-225 payload. Driven by the compelling clinical results in over 150 patients in multiple treatment settings and the high visibility of our NCI CRADA, we are seeing strong enthusiasm from investigators for Actimab-A. As the only CD33 targeted radiotherapy in development for myeloid malignancies, we are focused on capitalizing on the tremendous opportunity to improve outcomes for a significant patient population that continues to have high unmet medical needs that are not addressed by current therapies. Over the course of 2025, we expect to generate preclinical data and initiate additional clinical trials that will further differentiate Actimab-A and demonstrate material progress in establishing Actimab-A as a first-in-class backbone radiotherapy for the over 100,000 patients with AML and other myeloid malignancies in the U.S. and other major international markets."

"Last year was transformative for Lyell and now, based on promising emerging clinical data, we are poised to initiate pivotal development of IMPT-314, our next-generation dual-targeting CD19/CD20 CAR T-cell product candidate for patients with aggressive large B‑cell lymphoma," said Lynn Seely, M.D., Lyell’s President and CEO. "We believe IMPT-314 has the potential to deliver improved outcomes for patients by increasing complete response rates and prolonging the duration of response over approved CD19 CAR T-cell therapies, and this year we expect to share more mature data from the ongoing Phase 1/2 trial of IMPT-314. We also plan to initiate two pivotal programs for IMPT-314: one for patients in the 3rd line and later setting by the middle of this year and a second program for patients in the 2nd line setting by early 2026. In addition, we expect to submit a new IND in 2026 for a next-generation solid tumor CAR T-cell product candidate with a new target that is fully-armed with a suite of technologies, including our proprietary clinically-validated anti-exhaustion technology. Our strong cash position enables us to advance our pipeline through important clinical milestones and fund operations into 2027."
Fourth Quarter Updates and Recent Business Highlights
Lyell is advancing a pipeline of next-generation CAR T-cell product candidates. Its lead program, IMPT-314, is in Phase 1/2 clinical development for relapsed or refractory aggressive large B-cell lymphoma (LBCL) and its preclinical programs target solid tumor indications. Lyell’s programs target cancers with large unmet need with substantial patient populations.
IMPT-314: 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 the approved CD19‑targeted CAR T-cell therapies for the treatment of LBCL
IMPT-314 is an autologous CAR T-cell product candidate with a true ‘OR’ logic gate to target B cells that express either CD19 or CD20 with full potency and is manufactured with a process that enriches for CD62L+ cells to generate more naïve and central memory CAR T cells with enhanced stemlike features and antitumor activity. The ongoing Phase 1/2 clinical trial is a multi-center, open-label study designed to evaluate the tolerability and clinical benefit of IMPT-314 in patients with relapsed/refractory LBCL and determine a recommended Phase 2 dose. 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 in the 3rd line and later (3rd line+) setting.

•A Phase 1/2 clinical trial is ongoing and currently enrolling patients in the 3rd line+ and 2nd line settings who have not previously received CAR T-cell therapy.
•Initial data from the Phase 1/2 trial was presented at the American Society for Hematology 2024 Annual Meeting on December 9, 2024. Data from 23 patients with relapsed or refractory, CAR T-naive LBCL who received IMPT-314 were reported. 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 experiencing a 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 ICANS resolution of 5 days, and rapid improvement to Grade 2 or lower with standard therapy.
•More mature data from the ongoing Phase 1/2 trial in the 3rd line+ setting and initial data from patients in the 2nd line setting are expected to be presented in mid-2025.
•Pivotal trial in the 3rd line+ setting is expected to be initiated in mid-2025 in patients with relapsed/refractory aggressive LBCL who have not previously received CAR T-cell therapy.
•Pivotal trial in the 2nd line setting expected to be initiated by early 2026 in patients with relapsed/refractory aggressive LBCL who have not previously received CAR T-cell therapy.
Preclinical Pipeline, Technologies and Manufacturing Protocols
•The first IND for a fully-armed CAR T-cell product candidate with an undisclosed target for solid tumors is expected in 2026. Lyell is advancing next-generation fully-armed CAR T-cell product candidates, meaning they are armed with multiple technologies, each designed to address different barriers to effective cell therapies, including T-cell exhaustion, lack of durable stemness, as well as immune suppression within the hostile tumor microenvironment.
•Presented nonclinical and clinical data from cell therapy product candidates incorporating anti‑exhaustion and manufacturing technologies that demonstrated the potential of Lyell’s technologies to improve T‑cell function in solid tumors. These presentations, from multiple scientific conferences throughout the year, can be found at View Source
Corporate Updates
•Streamlined expenses and expect net cash use in 2025 to be between $175 million – $185 million. The disciplined expense management will be accomplished by focusing clinical development efforts on the pivotal trials of IMPT-314 and research efforts on developing next-generation fully-armed CAR T-cell programs for solid tumors.

Non‑GAAP R&D expenses, which exclude non-cash stock-based compensation and non-cash expenses related to the change in the estimated fair value of success payment liabilities, for the fourth quarter and year ended December 31, 2024 were $45.4 million and $157.3 million, respectively, compared to $42.9 million and $165.7 million for the same periods in 2023. The $2.5 million increase in fourth quarter 2024 non-GAAP R&D expenses was primarily driven by increased facilities costs. The $8.3 million decrease in annual 2024 non-GAAP R&D expenses was primarily driven by the decrease in personnel-related expenses mainly due to lower headcount following the Company’s November 2023 reduction in workforce.
•General and administrative (G&A) expenses were $14.5 million and $52.0 million for the fourth quarter and year ended December 31, 2024, respectively, compared to $13.2 million and $67.0 million for the same periods in 2023. The decrease in annual 2024 G&A expenses of $14.9 million was primarily driven by a decrease in non‑cash stock-based compensation. Non‑GAAP G&A expenses, which exclude non-cash stock‑based compensation, for the fourth quarter and year ended December 31, 2024 were $9.7 million and $33.5 million, respectively, compared to $8.5 million and $38.1 million for the same periods in 2023. The $1.3 million increase in fourth quarter 2024 non-GAAP G&A expenses was primarily driven by acquisition-related personnel expenses. The $4.6 million decrease in annual 2024 non-GAAP G&A expenses was primarily driven by the decrease in personnel-related expenses mainly due to lower headcount following the Company’s November 2023 reduction in workforce.
•Operating expenses for the fourth quarter and year ended December 31, 2024, include $87.2 million of acquired IPR&D expenses recognized as a part of the acquisition of ImmPACT Bio. Additionally, operating expenses for the fourth quarter and year ended December 31, 2024, include an impairment charge of $51.3 million for long-lived assets, resulting from the continued decline in our stock price and related market capitalization.
A discussion of non-GAAP financial measures, including reconciliations of the most comparable 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 December 31, 2024 were $383.5 million compared to $562.7 million as of December 31, 2023. Lyell believes that its cash, cash equivalents and marketable securities balances will be sufficient to meet working capital and capital expenditure needs into 2027.
