Elraglusib

Elraglusib represents a potential back bone therapy in pancreatic cancer with three ongoing trials in combination with current standards of care and novel immunotherapies Recent financing provides extended runway through key anticipated regulatory inflection points Additional nonclinical studies are ongoing combining elraglusib with RAS inhibitors based on potential synergies and complimentary mechanisms of action CHICAGO and FORT WORTH, Texas, Sept. 22, 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 a corporate update on the regulatory path for elraglusib in pancreatic cancer and anticipated milestones enabled by the recent $17.25 million public offering. Actuate has amended its investigational new drug (IND) application with updated clinical data from its international randomized Phase 2 trial in first-line treatment of metastatic pancreatic cancer (Actuate-1801 Part 3B), which showed a statistically significant improvement in median overall survival with the combination arm of elraglusib plus gemcitabine/nab-paclitaxel (GnP) versus GnP alone. These data are intended to support planned regulatory submissions with the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) beginning later this year and continuing into early 2026. The 1801-3β Phase 2 study is currently ongoing, with 22 patients in the elraglusib plus GnP arm either in active treatment or survival follow-up, ranging from 20 to 42 months in time on study, while only 3 patients remain in survival follow-up in the GnP arm, with time on study ranging from 21 to 23 months. These compelling results of elraglusib in combination with GnP, combined with early data demonstrating significant and durable long term responses in patients with highly metastatic disease treated with the combination of elraglusib/FOLFIRINOX/losartan in the ongoing clinical trial in patients with mPDAC led by Havard/MGH, plus the new clinical collaboration with Incyte and UPMC Hillman Cancer Center in patients with advanced pancreatic cancer using the combination of modified FOLFIRINOX and Incyte’s anti-PD-1 retifanlimab, further strengthen the case for elraglusib as a back-bone therapy that can be combined with different regimens used to treat this highly aggressive and deadly disease. “We are confident that our recently completed financing provides sufficient capital to support our corporate initiatives into the second half of 2026, and well through our upcoming anticipated interactions with the FDA and EMA. We have already updated the clinical data package on file with the FDA, and during the remainder of this year and into the first quarter of 2026, we expect to gain clarity on elraglusib’s regulatory path forward for the first-line treatment of metastatic PDAC,” said Daniel Schmitt, President & Chief Executive Officer of Actuate. “The survival benefit we’ve observed with elraglusib to date is compelling, and both its mechanism of action and safety profile support combination with chemotherapy, immunotherapy and potentially RAS inhibitors, increasing elraglusib’s potential as a backbone therapy, specifically in pancreatic cancers, where clinicians have limited options to extend and improve the lives of patients.” About Actuate-1801 Part 3β Study The Actuate-1801 Part 3β study (NCT03678883) is a randomized, controlled Phase 2 trial of elraglusib in combination with gemcitabine/nab-paclitaxel (GnP) versus GnP alone in first-line metastatic pancreatic adenocarcinoma (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. In the Phase 2 study, elraglusib in combination with GnP met its primary endpoint, showing a significant increase in median overall survival, a 37% reduction in the risk of death, and a doubling of the 12-month survival rate. In addition, 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, demonstrating elraglusib’s proposed immune modulating mechanism of action in patients with mPDAC. Inhibition of GSK-3β may inhibit pancreatic tumor growth and improve survival through several complimentary mechanisms that include enhancement of chemotherapy activity, regulation of anti-tumor immunity, and regulation of tumor 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.

All statements, other than statements related to present facts or current conditions or of historical facts, contained in this press release are forward-looking statements. Accordingly, these statements involve estimates, assumptions, substantial risks and uncertainties which could cause actual results to differ materially from those expressed in them, including but not limited to that preliminary and unpublished data may be subject to change and further interpretation following the availability of more data or following a more comprehensive review of the data and should not be relied upon as a final analysis; clinical and preclinical drug development involves a lengthy and expensive process with uncertain timelines and outcomes, results of prior preclinical studies, early clinical trials and sub-group studies are not necessarily predictive of future results and may not correlate with improved responses, and elraglusib may not achieve positive clinical results or favorable preclinical results or receive regulatory approval on a timely basis, if at all; that we may not successfully enroll additional patients or establish or advance plans for further development, including through conversations with the FDA or EMA and the standards such bodies may impose for such development; that elraglusib could be associated with side effects, adverse events or other properties or safety risks, which could delay or preclude regulatory approval, cause us to suspend or discontinue clinical trials or result in other negative consequences; our reliance on third parties to conduct our non-clinical studies and our clinical trials; our reliance on third-party licensors and ability to preserve and protect our intellectual property rights; that we face significant competition from other biotechnology and pharmaceutical companies; our ability to fund development activities, including because our financial condition raises substantial doubt as to our ability to continue as a going concern and we require additional capital to finance our operations beyond the second quarter of fiscal year 2026, and a failure to obtain this necessary capital in the near term on acceptable terms, or at all, could force us to delay, limit, reduce or terminate our development programs, commercialization efforts or other operations.
