CHICAGO and FORT WORTH, Texas, May 31, 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 presented 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) at the American Society of Clinical Oncology (ASCO) Annual Meeting.

Abstract Title: Preliminary results from the randomized phase 2 study (1801 Part 3B) of elraglusib in combination with gemcitabine/nab-paclitaxel (GnP) versus GnP alone in patients with previously untreated metastatic pancreatic ductal adenocarcinoma (mPDAC).
Abstract Number: 4006
Session Title: Gastrointestinal Cancer—Gastroesophageal, Pancreatic, and Hepatobiliary
Presenter: Devalingam Mahalingam, MD, PhD
Oral Presentation Date and Time: Saturday, May 31, 2025, 4:48 PM CDT

The trial met its primary endpoint of improved median overall survival. Median overall survival (mOS) increased by almost three months (10.1 months vs 7.2 months, HR=0.63, log-rank p=0.01) with a 37% reduction in the risk of death and strong statistical significance, representing a clinically meaningful advance in the potential treatment of mPDAC. Patients receiving elraglusib with GnP achieved a 12-month survival rate in 44.1% of patients treated—double that of GnP alone (22.3%).

Dr. Deva Mahalingam, MD, PhD, Northwestern University Feinberg School of Medicine, and lead principal investigator of the 1801 Part 3B trial commented, “Pancreatic cancer continues to represent one of the highest unmet medical needs with no major treatment advances in recent years, bar some molecular targets in small subsets of patients. New mechanisms of action are urgently needed. The addition of elraglusib to the existing chemotherapy backbone of gemcitabine and nab-paclitaxel is promising and may represent a meaningful therapeutic advance for patients with pancreatic cancer.” 

Daniel Schmitt, President & Chief Executive Officer of Actuate added, “We significantly improved mOS, cut the risk of death by 37%, and doubled the 12-month survival rate. Combined with a manageable safety profile and strong emerging mechanistic insights, these results reinforce the transformative potential of our GSK-3β inhibitor program. Based on the clear clinical benefit and well-tolerated safety profile, we intend to engage with the FDA and EMA in the second half of this year to align on a path to registration. We believe this enables us to move rapidly towards commercialization and delivery of this first-in-class therapy to patients with an urgent unmet need.”

Efficacy

• Figure 1 below depicts the Kaplan-Meier estimate for mOS (10.1 months vs 7.2 months, HR=0.63, log-rank p=0.01) with a 37% reduction in the risk of death, displaying a clear clinical survival benefit for patients treated in the elraglusib/GnP combination arm vs GnP alone arm.

• 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.

Safety and Biomarker Findings

• 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.
