Key Terms

clinical benefit rate, overall survival, progression-free survival, immune checkpoint inhibitor, +2 more
6 terms
clinical benefit rate clinical
"DURIPANC’s primary endpoint is Clinical Benefit Rate (“CBR”), defined as the proportion..."
The clinical benefit rate is the share of patients in a medical study who experience a meaningful positive treatment effect — usually tumor shrinkage, disappearance, or disease staying stable for a set period — rather than their condition worsening. Investors care because it gives a broader picture of a therapy’s real-world usefulness beyond quick responses, like judging how many cars in a road test actually arrive without breaking down, which helps predict commercial and regulatory prospects.
overall survival clinical
"DURIPANC’s Secondary Endpoints include Overall Survival (“OS”) – the gold standard..."
Overall survival is the average or median length of time patients remain alive after starting a treatment or entering a clinical study, measured regardless of cause of death. Investors care because it is a clear, hard measure of a therapy’s real-world benefit — like timing how long a new battery actually runs — and strong improvements in overall survival can drive regulatory approval, market adoption and revenue potential.
progression-free survival clinical
"DURIPANC’s Secondary Endpoints include Overall Survival (“OS”) – the gold standard in oncology trials – as well as progression-free survival..."
Progression-free survival is the length of time during and after a treatment that a patient's disease does not get worse, measured from the start of treatment until the disease shows measurable signs of progression or the patient dies. Investors care because longer progression-free survival in clinical trials often signals that a drug is effective, improving chances of regulatory approval, market adoption, and revenue potential—think of it as a stopwatch showing how long a therapy can keep the illness at bay.
immune checkpoint inhibitor medical
"evaluating Ampligen ... in combination with AstraZeneca’s anti-PD-L1 immune checkpoint inhibitor Imfinzi..."
An immune checkpoint inhibitor is a type of medicine that helps the body's immune system recognize and attack cancer cells more effectively. It works by blocking certain signals that cancer uses to hide from immune defenses, allowing the immune system to target tumors. This breakthrough has led to new cancer treatments, making immune checkpoint inhibitors an important area of growth and innovation in the healthcare industry.
neutrophil/lymphocyte ratios clinical
"Based upon stratification for immune marker Neutrophil/Lymphocyte ratios less than 4.5..."
The neutrophil/lymphocyte ratio is a simple blood test result that compares two types of white blood cells—neutrophils (first responders to infection) and lymphocytes (specialized immune defenders)—to show the balance of inflammation versus targeted immune activity. Investors watch this ratio because changes can signal how well a patient or population is responding to a therapy, predict clinical outcomes, or influence trial endpoints and regulatory decisions, much like a single dashboard light that hints at overall system health.
ca 19-9 clinical
"Based upon stratification for immune marker CA 19-9 less than 1000..."
CA 19-9 is a blood test that measures a specific protein often produced at higher levels by certain digestive-system cancers, most notably pancreatic cancer. For investors, it matters because changes in CA 19-9 levels can signal whether a treatment or diagnostic is working, influence clinical trial decisions and regulatory paths, and affect the commercial prospects of drugs or tests—think of it as a smoke alarm that helps detect and track a possible fire.

Study results expected to support design and initiation of a pivotal Phase 3 clinical trial in the treatment of metastatic pancreatic cancer

OCALA, Fla., June 18, 2026 (GLOBE NEWSWIRE) -- AIM ImmunoTech Inc. (NYSE American: AIM(“AIM” or the “Company”) today announced that the final subject has received their first dose in the Phase 2 DURIPANC clinical trial evaluating Ampligen® (rintatolimod) in combination with AstraZeneca’s anti-PD-L1 immune checkpoint inhibitor Imfinzi® (durvalumab) for the treatment of metastatic pancreatic cancer.

With this final subject, Primary Endpoint analysis is anticipated to begin in December 2026 and topline results are anticipated in Q1 2027. DURIPANC’s primary endpoint is Clinical Benefit Rate (“CBR”), defined as the proportion of patients achieving stable disease, partial response or complete response at 24 weeks following initiation of combination therapy.

Analysis of Secondary Endpoints is expected to begin in June 2027, or 49 weeks after this final subject received their first dose. DURIPANC’s Secondary Endpoints include Overall Survival (“OS”) – the gold standard in oncology trials – as well as progression-free survival and immune profiling analysis that could potentially help identify subsets of future pancreatic cancer patients likely to experience the best survival results, which could be critical to the design of a pivotal Phase 3 clinical trial.

AIM Chief Executive Officer Thomas K. Equels stated: “AIM hopes to utilize the exploratory biomarker data generated through DURIPANC to design a Phase 3 study involving Ampligen in the treatment of pancreatic cancer. We are particularly interested in evaluating whether specific biomarkers may help to identify ‘super-responder’ patient subsets most likely to benefit from Ampligen-based therapy, thus supporting a more targeted and personalized treatment approach.”

DURIPANC is a follow-up to the AIM/Erasmus Medical Center Named Patient Program utilizing Ampligen as a monotherapy in late-stage pancreatic cancer, where data suggested impressive improvements in survival, particularly when broken down by biomarker stratifications:

  • Based upon stratification for immune marker Neutrophil/Lymphocyte ratios less than 4.5, Progression-Free Survival (“PFS”) of 17.7 months compared to 8.6 months for historical controls, for an improvement of 9.1 months in PFS
  • Based upon stratification for immune marker Neutrophil/Lymphocyte ratios less than 4.5, OS of 34.8 months compared to 12.5 months for historical controls, for an improvement of 22.3 months in OS
  • Based upon stratification for immune marker CA 19-9 less than 1000, PFS of 13.1 months compared to 8.6 months for historical controls, for an improvement of 4.5 months in PFS
  • Based upon stratification for immune marker CA 19-9 less than 1000, OS of 24.1 months compared to 12.5 months for historical controls, for an improvement of 11.6 months in OS

These results were accompanied by consistent reports of improved quality of life.

About DURIPANC

DURIPANC is an investigator-initiated, exploratory, open-label, single-center Phase 2 study. The clinical trial is a joint collaboration between AIM, AstraZeneca and Erasmus Medical Center in the Netherlands. In addition to the Primary Endpoint of clinical benefit rate, 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.
