OCALA, Fla., Nov. 05, 2026 (GLOBE NEWSWIRE) -- AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”) today announced the release of a new investor presentation, “The Ampligen Opportunity,” highlighting the potential for Ampligen (rintatolimod) to complement emerging RAS-targeted therapies in pancreatic cancer, including Revolution Medicines’ Rasonque™ (daraxonrasib).

The presentation examines recent advances in pancreatic cancer treatment and the scientific rationale for combining RAS inhibition with immune stimulation to potentially enhance and extend clinical benefit. It also highlights previously reported Ampligen clinical observations, the ongoing Phase 2 DURIPANC program and anticipated 2027 milestones.

AIM Chief Executive Officer Thomas K. Equels states: “Ampligen has been demonstrated to be a powerful innate immunomodulator with broad-spectrum anti-tumor proliferation effects, while the RAS-targeted therapy daraxonrasib represents a new and promising development which, I believe, will likely become a first-line therapy for pancreatic cancer. I see great potential in bringing the two together. While daraxonrasib targets the signaling pathways that drive tumor growth, Ampligen is designed to stimulate innate and adaptive immune responses, which helps set Ampligen apart among late-stage clinical trials for pancreatic cancer. We believe these potentially complementary mechanisms of action provide a compelling foundation for investigating how Ampligen might enhance and prolong the benefits of targeted RAS treatment, which is especially significant because of daraxonrasib’s potential to become the standard of care therapy for pancreatic cancer in the very near future.”

Key Highlights from the Investor Presentation

Daraxonrasib’s Phase 3 Results and the Potential for Complementary Treatment Strategies

The presentation highlights results from the randomized Phase 3 RASolute 302 study evaluating daraxonrasib against investigators’ choice of chemotherapy in previously treated metastatic pancreatic ductal adenocarcinoma.

In the overall study population, daraxonrasib demonstrated:

• Median overall survival of 13.2 months versus 6.7 months with chemotherapy (hazard ratio: 0.40).
• Median progression-free survival of 7.2 months versus 3.6 months with chemotherapy (hazard ratio: 0.49).
  
  

These findings underscore the progress being made in RAS-targeted treatment and the opportunity to investigate strategies that may further extend disease control.

Complementary Mechanisms Support Further Investigation

Daraxonrasib inhibits RAS(ON) signaling involved in tumor growth, while Ampligen is an investigational Toll-like receptor 3 (TLR3) agonist designed to stimulate innate and adaptive immune responses.

Previously published research involving Ampligen has demonstrated immune modulation involving dendritic cells and T-cell responses. AIM believes these distinct mechanisms support further investigation of whether Ampligen could enhance anti-tumor immune activity alongside RAS inhibition.

The proposed combination remains investigational, and its safety, efficacy and potential to improve outcomes beyond daraxonrasib alone have not been established.

Previously Reported Ampligen Clinical Observations Provide an Encouraging Foundation

The presentation highlights findings from a Netherlands government-approved Named Patient Program evaluating Ampligen following FOLFIRINOX chemotherapy in patients with advanced pancreatic cancer.

In this nonrandomized program, 57 Ampligen-treated patients were compared with 27 historical controls. Exploratory findings included:

• Median overall survival of 19.7 months versus 12.5 months in historical controls.
• Median progression-free survival of 12.6 months versus 8.6 months in historical controls.
• Median overall survival of 34.8 months in an Ampligen-treated subgroup with a baseline neutrophil-to-lymphocyte ratio of 4.5 or less, versus 19.3 months among Ampligen-treated patients with higher ratios.
  
  

DURIPANC Program Advancing Toward Key 2027 Clinical Milestones

AIM’s ongoing Phase 1/2 DURIPANC study is evaluating Ampligen in combination with durvalumab (Imfinzi^®) in patients with metastatic pancreatic cancer who achieved stable disease following FOLFIRINOX chemotherapy.

The study enrolled 28 patients across Phase 1 and Phase 2. The Phase 2 primary endpoint is clinical benefit rate at 24 weeks. To date, the clinical trial has met each milestone on schedule.

Previously reported interim findings include encouraging tolerability, with only three Grade 3 immune-related adverse events; consistently high patient-reported quality of life; and preliminary evidence of coordinated innate and adaptive immune activation.

AIM anticipates the following milestones:

• Q1 2027: Phase 2 topline results evaluating clinical benefit rate at 24 weeks.
• Q3 2027: Additional analyses of overall survival, progression-free survival, quality of life and immune responses.
  
  

These findings are expected to help inform future development opportunities, including the potential design of a pivotal Phase 3 trial.

Exploring the Potential to Extend RAS-Targeted Treatment Benefits

The presentation also outlines a proposed development strategy to investigate whether adding Ampligen to ongoing daraxonrasib treatment, or as a post-daraxonrasib maintenance therapy, could strengthen anti-tumor immune responses and potentially extend disease control.

Potential evaluations include safety, biological activity, treatment timing, progression-free survival and duration of response. This proposed strategy is not an established clinical trial protocol, and additional research would be required to evaluate the combination.

Positioning Ampligen for the Evolving Pancreatic Cancer Treatment Landscape

As RAS-targeted therapies continue to advance, AIM believes Ampligen’s immunomodulatory mechanism and existing clinical observations provide a foundation for exploring complementary treatment strategies.

With anticipated DURIPANC milestones in 2027, the Company remains focused on generating additional clinical evidence while evaluating opportunities to expand Ampligen’s potential role in pancreatic cancer treatment.
