Actuate Therapeutics Reports Positive Follow-Up Data from its Randomized Controlled Phase 2 Trial Demonstrating Extended Long-Term Overall Survival Benefit with Elraglusib Plus Chemotherapy for Metastatic Pancreatic Cancer in Oral Presentation at ASCO GI 2026

• Phase 2 study met its primary endpoint, demonstrating statistically significant improved overall survival with elraglusib plus gemcitabine/nab-paclitaxel versus chemotherapy alone
• Elraglusib combination reduced the risk of death by 38% compared with gemcitabine/nab-paclitaxel alone, with increased durable survival observed beyond 24 months

CHICAGO and FORT WORTH, Texas, Jan. 12, 2026 (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 that new additional and promising patient survival and biomarker data from treatment with elraglusib for metastatic pancreatic cancer were featured in oral and poster presentations at the 2026 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO GI) on January 9, 2026. The presentations highlighted new, expanded data from the Company’s Phase 2 clinical program (Actuate 1801-Part 3B) evaluating elraglusib in combination with gemcitabine/nab-paclitaxel (GnP), a first-line chemotherapy regimen for metastatic pancreatic cancer, providing additional evidence that suggests that elraglusib combined with GnP is associated with improved survival when compared with GnP alone.

“Pancreatic cancer continues to have a high unmet medical need, particularly at the metastatic stage,” said Dr. Devalingam Mahalingam, MD, PhD. “The results from this Phase 2 study suggest that adding elraglusib to standard gemcitabine and nab-paclitaxel chemotherapy may improve survival outcomes while maintaining a manageable safety profile. The scope of this trial, which enrolled 286 patients across 60 sites in six countries, underscores the robustness of the dataset. We are grateful to the patients and their families whose participation made this research possible.”

“Metastatic pancreatic cancer remains one of the most difficult cancers to treat, with few effective first-line options,” said Dan Schmitt, Chief Executive Officer of Actuate Therapeutics. “In this randomized Phase 2 study, the addition of elraglusib to gemcitabine and nab-paclitaxel resulted in a meaningful improvement in overall survival compared with chemotherapy alone. As of November 2025, seventeen patients are still alive in the elraglusib/GnP arm, and three of them have remarkably passed the 24-month mark on first-line treatment, while no patients remain on GnP treatment alone. Current patient survival for metastatic pancreatic cancer is less than 12 months, so our findings are especially encouraging. We look forward to building from this data and continuing to advance elraglusib for patients with this devastating disease.”

Key Findings:

Efficacy: The primary efficacy endpoints were met in this study:

• The median overall survival (OS) showed significant benefit in the elraglusib/GnP vs GnP alone arms (mOS 10.1 months vs. 7.2 months, p=0.02, HR=0.62)
• 12-month survival rate doubled to 44.4% (elraglusib/GnP) vs 22.3% (GnP)  
• 24-month survival rate increased fivefold to 12.9% in the elraglusib/GnP arm compared to 2.6% in the GnP arm, emphasizing the potential for long-term clinical benefit.

Safety: The safety and tolerability profile of elraglusib was consistent with previously reported data at the 9.3 mg/kg dose, and no new safety signals were identified:

• Serious TEAE were similar between the elraglusib/GnP (56.1%) and the GnP alone arm (56.4%),
• TEAE resulting in death were similar between treatment arms: elraglusib/GnP (12.3%) and GnP alone (16.7%)
• Grade-3 or higher TEAE leading to stoppage of any study drug: elraglusib/GnP (16.8%) and GnP alone (21.8%)

Genomic biomarkers: Several mutations commonly associated with pancreatic cancer were identified as potential predictive biomarkers of overall survival in the elraglusib/GnP arm, but not in the GnP-alone arm. Actionable mutations like KRAS or ARID1A could suggest novel drug combinations for future clinical studies.

Immunological biomarkers: The percentage of CD8+ and Granzyme B+ cells, as well as NK cells, was increased in tumors obtained from elraglusib/GnP-treated patients but not in GnP-treated patients, suggesting that combination therapy may potentiate improved anti-tumor immune response.

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.

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.
