**DURIPANC, Year-End Interim Clinical Progress Update**

***A Phase I/II Open Label Study of Durvalumab (Imfinzi) and Rintatolimod (Ampligen) in Pancreatic Cancer Patients with Stable Disease Post-FOLFIRINOX***

DURIPANC (NCT05927142) is an exploratory, single-arm study examining the use of Durvalumab (anti–PD-L1) combined with Rintatolimod (Ampligen) in patients with metastatic pancreatic ductal adenocarcinoma (PDAC) who have stable disease after standard FOLFIRINOX chemotherapy. The study aims to assess safety, initial effectiveness, quality of life, and immune response patterns.

**Patient Enrollment & Treatment**

18 patients have been enrolled. Eligibility included confirmed PDAC with stable disease after 8 cycles of FOLFIRINOX, and an ECOG score of 0–1. The treatment regimen consisted of Durvalumab (12 doses administered every 28 days) combined with Rintatolimod (given twice weekly for six weeks or until disease progression or unacceptable toxicity). Key Interim Findings (Cutoff: Dec 1, 2025)

**Safety**

Combination therapy is usually well-tolerated, with just two grade 3 immune-related adverse events and no unexpected toxicities observed.

**Efficacy**

The promising Progression-Free Survival and Overall Survival seen in Phase 1 of the study – which supported advancement to the ongoing Phase 2 portion of the study – continues to be seen and enrollment is ongoing. Erasmus MC expects that detailed data will be published later this year.

**Quality of Life**

Patients consistently reported a high quality of life throughout treatment, especially in an advanced PDAC cohort.

**Immune Profiling**

Initial immune profiling shows encouraging trends. The detected immunologic alterations demonstrate a coordinated activation by the combination of Ampligen with Durvalumab of both innate and adaptive immune responses after therapy.

**Phase I Study Outcome**

The Phase I safety run-in was successfully completed, demonstrating a manageable safety profile. The encouraging results supported moving forward to Phase II of the study, which is planned to enroll up to 25 patients, to further assess clinical benefit.

**Context & Comparison**

Historically, immunotherapy after FOLFIRINOX has had limited success, with a median PFS of under 2 months in similar trials. DURIPANC, however, shows promising safety, preserved quality of life, and encouraging immune response. This, together with the clinical results, warrants further evaluation in the Phase II trial and enrollment is continuing.

**Next Steps**

Ongoing monitoring to evaluate the durability of responses and long-term survival. The comprehensive study results and detailed immune analyses will be presented in the final report and subsequent publications.

**Conclusion**

The combination of Durvalumab and Rintatolimod is safe and well-tolerated, maintained quality of life and immune system changes suggest a coordinated activation of innate and adaptive responses, supporting further investigation of this combination in post-FOLFIRINOX patients with PDAC. The Phase I outcomes offer a solid basis for the Phase II to better assess clinical efficacy.

**AIM ImmunoTech Reports Positive Year-End Interim Clinical Progress from Phase 2 Study**

**Evaluating Ampligen® (rintatolimod) in Combination with AstraZeneca's Imfinzi®**

**(durvalumab) for the Treatment of Pancreatic Cancer**

 ****

*Year-end report discusses combination therapy's Mechanism of Action activating both innate and adaptive immune responses*

**OCALA, Fla., February 5, 2026/ <u>AIM ImmunoTech Inc.</u> (NYSE American: AIM)** ("AIM" or the "Company") today reported positive data in a year-end update from the ongoing Phase 2 clinical study evaluating AIM's drug Ampligen® (rintatolimod) combined with AstraZeneca's anti-PD-L1 immune checkpoint inhibitor Imfinzi® (durvalumab) in the treatment of metastatic pancreatic cancer patients with stable disease post-FOLFIRINOX standard of care (the "DURIPANC" study) (see: <u>ClinicalTrials.gov NCT05927142</u>). This is a follow-up Phase 2 to a 57-subject early access program ("EAP") of Ampligen as a monotherapy in late-stage pancreatic cancer, where Ampligen was associated with median survival of 19.7 months, which is an extension of median overall survival of 8.6 months when compared to the standard of care. The EAP subjects also reported improved quality of life.

AIM CEO Thomas K. Equels states: "We know all too well that metastatic pancreatic cancer is a killer. Ampligen has the potential to be a gamechanger in the treatment of this highly lethal and unmet oncological need. Quality of life for pancreatic cancer patients is extremely painful and subject to co-morbidities due to the tumor-induced immune suppressive state. Additionally, other metastatic pancreatic cancer chemotherapies and immunotherapies typically have harsh side effects. However, Erasmus has informed us that the pancreatic cancer patients who received Ampligen have reported meaningful improvements in their quality of life. This data sharply focuses our aim on late-stage pancreatic cancers, which killed more than 100,000 people in the American and European Union markets and more than 450,000 people worldwide as recently as 2022. I do not believe there is any other therapeutic in this stage of the pipeline that is producing these types of survival results combined with improvement in quality of life."

The DURIPANC study is an investigator-initiated, exploratory, open-label, single-center study expected to enroll up to 25 subjects in the Phase 2 portion. The clinical trial is a joint collaboration between AIM, AstraZeneca and Erasmus Medical Center ("Erasmus MC") in the Netherlands. The primary objective of the study is the clinical benefit rate of the combination therapy. The secondary/exploratory objectives include assessing overall survival (OS) and progression-free survival (PFS); exploring immune-monitoring using available tissue biopsies and peripheral immune profiling; and assessing quality of life.

Eighteen patients have been enrolled in the study. Lead investigator Marjolein Y. V. Homs, MD, PhD, Department of Medical Oncology, Erasmus MC Cancer Institute, emphasized that the promising Progression-Free Survival and Overall Survival seen in Phase 1 of the study – which supported advancement to the ongoing Phase 2 portion of the study – continue to be seen and that enrollment is ongoing. Erasmus MC expects that detailed data will be published later this year.

According to Erasmus MC, there has also been no significant toxicity – an encouraging safety profile for a post-chemo setting – and Ampligen subjects are consistently reporting "high quality of life" during treatment.

See: *<u>DURIPANC, Year-End Interim Clinical Progress Update</u>*

Prof. Casper van Eijck, MD, PhD, of Erasmus MC, states: "Erasmus MC clinicians and researchers are seeing immune system changes that suggest a coordinated activation of innate and adaptive responses – or, to put it more simply, the combination of Ampligen and Durvalumab seems to be enhancing the body's natural immune system. This perceived mechanism of action together with the clinical results supports continued investigation of this combination in post-FOLFIRINOX patients with pancreatic ductal adenocarcinoma."

Additionally, AIM has published on its website an updated corporate presentation that emphasizes the Company's priority goal of a new drug approval for Ampligen in the treatment of pancreatic cancer. The presentation details AIM's research and development work in pancreatic cancer; how Ampligen is believed to work in the treatment of pancreatic cancer; and why AIM believes that pancreatic cancer research and development holds the most potential for AIM's stockholders. The <u>largest mergers and acquisitions deals in the biotech space</u> often involve oncology drugs in Phase 3 clinical trials or later in development, and so AIM believes that moving Ampligen toward – and ultimately into – a Phase 3 clinical trial has great financial potential for the Company and its stockholders.

*See: <u>Ampligen Breakthroughs in Treating Late-Stage Pancreatic Cancer: Corporate Presentation – February 2026</u>*

AIM's intellectual property portfolio includes <u>a U.S. patent for Ampligen</u> as an oncology treatment in combination with anti-PD-L1 therapies, similar to that seen in the DURIPANC clinical trial combining Ampligen and AstraZeneca's durvalumab; this patent extends protection to August 9, 2039. AIM has also been awarded orphan drug designations in pancreatic cancer by both the <u>United States</u> and the <u>European Union</u>, granting years of market exclusivity to AIM for Ampligen post-commercial approval.

Equels adds: "This patent protection and the orphan drug designations' market exclusivity have the potential to create great value for our stockholders in this large-market unmet medical need."
