CHICAGO and FORT WORTH, Texas, June 02, 2025 (GLOBE NEWSWIRE) -- Actuate Therapeutics, Inc. (NASDAQ:ACTU) ("Actuate" or the "Company"), a clinical-stage biopharmaceutical company focused on developing therapies for the treatment of high-impact, difficult-to-treat cancers through the inhibition of glycogen synthase kinase-3 beta (GSK-3β), today announced key takeaways from its Key Opinion Leader (KOL) event held on May 31, 2025 discussing the positive topline results from the Phase 2 (Actuate-1801 Part 3B) trial of elraglusib in combination with gemcitabine/nab-paclitaxel (GnP) in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (mPDAC).

The study met its primary endpoint, demonstrating a clinically meaningful increase in median overall survival (mOS) of 10.1 months compared to 7.2 months (p = 0.01), with a 37% reduction in the risk of death (HR = 0.63). The elraglusib/GnP arm also doubled the 12-month survival rate in 44.1% of patients compared to GnP alone (22.3%), with a favorable safety profile.

The KOL event followed the presentation of topline trial data during an oral session at the American Society of Clinical Oncology (ASCO) Annual Meeting. The event featured a fireside discussion with leading mPDAC clinicians, all with direct participation in the elraglusib clinical trial program: Colin Weekes, MD, PhD, Massachusetts General Hospital; Devalingam Mahalingam, MD, Northwestern University Feinberg School of Medicine; Rachna Shroff, MD, MS, FASCO, University of Arizona Cancer Center; Tanios Bekaii-Saab, MD, FACP, Mayo Clinic College of Medicine and Science.

The panelists highlighted the implications of the Phase 2 Actuate 1801 Part 3B results in the broader context of the unmet need in mPDAC, the unique immune-modulating mechanism of elraglusib, and its potential to reshape the treatment landscape, as follows.

Daniel Schmitt, President & Chief Executive Officer of Actuate said, "The reception we received at ASCO confirms what we already believed - this data has the potential to change the trajectory of mPDAC treatment. As our KOLs highlighted in the panel discussion, there is a clear need for new drugs, like elraglusib, with new mechanistic pathways, and which can be successfully combined without overlapping toxicities for treatment of this devastating disease. As these thought leaders pointed out, due to a number of negative trials, there has been quite some time since we've had anything that improves outcomes for patients with these chemotherapy backbones. The thought leaders further highlighted the importance of the overall survival benefit and noted the magnitude of that benefit in the elraglusib trial is actually substantial. We are now laser-focused on turning this promise into patient access. With a clear survival benefit, favorable safety profile, and strong scientific rationale, we look forward to advancing elraglusib development and initiating regulatory discussions with both the FDA and EMA."

Key highlights from the ASCO oral presentation:

In addition to the improved mOS and one-year survival rate, a continued survival benefit was also observed at eighteen and twenty-four months (survival rates of 19.7% vs 4.4% and 13.8% vs 0% in the elraglusib/GnP combination arm vs the GnP arm, respectively).
The elraglusib/GnP combination treatment also resulted in numerically improved overall response rates (29.0% in the elraglusib/GnP combination arm vs 21.8% in the GnP arm) and improvements in median progression-free survival and median duration of response of 5.6 months vs 5.1 months, and 5.5 months vs 4.0 months in the elraglusib/GnP combination arms vs GnP arms, respectively.
The trial also met its primary safety endpoint. Treatment-emergent adverse events (TEAEs) and Serious Adverse Events (SAEs) in the elraglusib/GnP combination arm were similar to those observed in the GnP arm, indicating a favorable risk-benefit profile for the elraglusib/GnP combination.
- Treatment-related adverse events (TRAEs) were mostly Grade 1-2, with the most frequent TRAEs observed (in about two-thirds of patients) being transient visual impairments that were reversible and non-progressive
- While Grade 3 or higher neutropenia was observed, similar rates of febrile neutropenia and sepsis were observed in both treatment arms.
Pre-dose cytokine analysis that suggested lower baseline levels of key immune modulators, including CCL3, IL-1α, IL-18, TGF-β, and TRAIL R3, were correlated with improved 1-year survival.
Increased CD8-positive and granzyme B-positive T cells, increased NK cells, and decreased myeloid-derived suppressor cells were observed in tumor biopsies only from elraglusib-treated patients. This exploratory result confirms elraglusib proposed immune modulating mechanism of action in patients with mPDAC.

About Actuate-1801 Part 3B Study

The Actuate-1801 Part 3B study (NCT03678883) is a randomized, controlled Phase 2 trial of elraglusib with GnP versus GnP alone in first-line mPDAC. The trial enrolled 286 mPDAC patients with no prior systemic treatment for metastatic disease, who were randomized 2:1 to the elraglusib treatment arm (elraglusib + GnP) or the control arm (GnP alone). Elraglusib is administered at a dose of 9.3 mg/kg by IV infusion on Day 1 of each week of a 28-day cycle. The primary endpoint for this study is median overall survival, with OS summarized throughout the study by estimates of 1-year survival. Secondary endpoints are DCR, ORR, PFS, and AE.

Inhibition of GSK-3β may inhibit tumor growth and improve survival through several complimentary mechanisms that include enhancement of chemotherapy activity, activation of innate anti-tumor immunity, and regulation of gene expression, leading to alterations in tumor metabolism and Epithelial-to-Mesenchymal Transition (EMT).

About Actuate Therapeutics, Inc.

Actuate is a clinical-stage biopharmaceutical company focused on developing therapies for the treatment of high-impact, difficult-to-treat cancers. Actuate's lead investigational drug, elraglusib (a novel GSK-3β inhibitor), targets molecular pathways in cancer that are involved in promoting tumor growth and resistance to conventional cancer drugs such as chemotherapy through the inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kB) and DNA Damage Response (DDR). Elraglusib may also mediate anti-tumor immunity through the regulation of multiple immune checkpoints and immune cell function.
