In the trial, the gedatolisib triplet demonstrated a statistically significant and clinically meaningful improvement in PFS among patients, reducing the risk of disease progression or death by 76% compared to fulvestrant (based on a hazard ratio [HR] of 0.24, 95% confidence interval [CI] 0.17-0.35; p<0.0001). The mPFS, as assessed by blinded independent central review ("BICR"), was 9.3 months with the gedatolisib triplet versus 2.0 months with fulvestrant, an incremental improvement of 7.3 months.

The gedatolisib doublet also demonstrated a statistically significant and clinically meaningful improvement in PFS among patients, reducing the risk of disease progression or death by 67% compared to fulvestrant (HR of 0.33, 95% CI 0.24-0.48; p<0.0001). The mPFS, as assessed by BICR, was 7.4 months with the gedatolisib doublet versus 2.0 months with fulvestrant, an incremental improvement of 5.4 months.

The topline efficacy data from the VIKTORIA-1 PIK3CA wild-type cohort established several new milestones in the history of drug development for HR+/HER2- advanced breast cancer:

· The hazard ratios for the gedatolisib triplet and doublet are more favorable than have ever been reported by any Phase 3 trial for patients with HR+/HER2- ABC.

· The 7.3- and 5.4-months incremental improvements in median PFS for the gedatolisib triplet and gedatolisib doublet over fulvestrant, respectively, are higher than have ever been reported by any Phase 3 trial for patients with HR+/HER2- ABC receiving at least their second line of therapy.

· Gedatolisib is the first inhibitor targeting the PI3K/AKT/mTOR pathway to demonstrate positive Phase 3 results in patients with HR+/HER2-/PIK3CA wild-type ABC whose disease progressed on or after treatment with a CDK4/6 inhibitor.

Sara Hurvitz, MD, Senior Vice President, Clinical Research Division, Fred Hutchinson Cancer Center, Professor and Head, Division of Hematology and Oncology, University of Washington, Department of Medicine and co-principal investigator for the trial said: "Patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer whose disease has progressed while on, or after, treatment with a CDK4/6 inhibitor typically derive limited benefit from subsequent endocrine-based therapy. The topline data for both gedatolisib regimens from VIKTORIA-1 are potentially practice-changing. To my knowledge, we have not seen Phase 3 results in patients with HR-positive, HER2-negative advanced breast cancer before where there was a quadrupling of the likelihood of survival without disease progression relative to the study control."

Treatment discontinuation due to a treatment-related adverse event for the gedatolisib triplet and gedatolisib doublet was lower than was observed in Arm D of the Phase 1b trial in patients with ABC, and lower than observed in any Phase 3 trials for currently approved drug combinations in HR+/HER2- ABC. Additionally, the gedatolisib triplet and gedatolisib doublet were better tolerated than was observed in the Phase 1b trial in patients with ABC, including lower rates of hyperglycemia and stomatitis.

Igor Gorbatchevsky, MD, Chief Medical Officer of Celcuity said: "The topline data from VIKTORIA-1 demonstrate the potential for gedatolisib to become a transformative new medicine for the treatment of patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer whose disease progressed on or after treatment with CDK4/6 inhibitors. The 7.3 and 5.4-months incremental improvement in median PFS relative to fulvestrant for the gedatolisib regimens are potentially paradigm shifting results. We are also very excited that treatment with gedatolisib combined with fulvestrant with or without palbociclib was well-tolerated by the VIKTORIA-1 patients and that only a few patients discontinued treatment due to an adverse event."

Brian Sullivan, Chairman, Chief Executive Officer and co-founder of Celcuity said, "The efficacy improvement relative to the control that each of the gedatolisib regimens demonstrated was historic for this patient population. We are excited about the potential opportunity to provide a breakthrough therapeutic option for patients with HR-positive, HER2-negative, PIK3CA wild-type advanced breast cancer."

Full data from the PIK3CA wild-type cohort of the VIKTORIA-1 clinical trial will be presented at an upcoming medical conference later this year. Celcuity expects to submit a New Drug Application for gedatolisib to the U.S. Food and Drug Administration in the fourth quarter of 2025. Topline data for the VIKTORIA-1 PIK3CA mutation cohort is expected by the end of 2025.

Webcast and Conference Call Information

The Celcuity management team will host a webcast/conference call on Monday, July 28, 2025, at 8:00 a.m. ET to discuss the topline results from the Phase 3 VIKTORIA-1 trial. Those who would like to participate may access the live webcast here, or register in advance for the teleconference here. A replay of the webcast will be available on the Celcuity website following the live event.

Notes

HR+/HER2- Breast cancer

Breast cancer is the second most common cancer and one of the leading causes of cancer-related deaths worldwide.1 More than two million breast cancer cases were diagnosed globally in 2022.1 While survival rates are high for those diagnosed with early breast cancer, only approximately 30% of patients who are diagnosed with or who progress to metastatic disease are expected to live five years after their diagnosis.2 HR+/HER2- breast cancer is the most common subtype of breast cancer, accounting for approximately 70% of all breast cancers.2

Three interconnected signaling pathways, estrogen, cyclin D1-CDK4/6, and PI3K/AKT/mTOR (PAM), are primary oncogenic drivers of HR+, HER2- breast cancer.3 Therapies inhibiting these pathways are approved and used in various combinations for advanced breast cancer. Currently approved inhibitors of the PAM pathway for breast cancer target a single PAM pathway component, such as PI3Kα, AKT, or mTORC1.4,5,6,7 However, resistance to CDK4/6 inhibitors and current endocrine therapies develops in many patients with advanced disease.8 Survival rates are low with 30% of patients anticipated to live beyond five years after diagnosis.2 Optimizing the inhibition of the PAM pathway is an active area of focus for breast cancer research.

VIKTORIA-1

VIKTORIA-1 is a Phase 3 open-label, randomized clinical trial to evaluate the efficacy and safety of gedatolisib in combination with fulvestrant with or without palbociclib in adults with HR+/HER2- ABC whose disease progressed on or after prior CDK4/6 therapy in combination with an aromatase inhibitor. The clinical trial is enrolling subjects regardless of PIK3CA status while enabling separate evaluation of subjects according to their PIK3CA status. Subjects who meet eligibility criteria and do not have confirmed PI3KCA mutations (WT) were randomly assigned (1:1:1) to receive a regimen of either gedatolisib, palbociclib, and fulvestrant, gedatolisib and fulvestrant, or fulvestrant. Subjects who meet eligibility criteria and have confirmed PI3KCA mutations (MT) are randomly assigned (3:3:1) to receive a regimen of either the gedatolisib triplet, alpelisib and fulvestrant, or the gedatolisib doublet.

Gedatolisib

Gedatolisib is an investigational, multi-target PAM inhibitor that potently targets all four class I PI3K isoforms, mTORC1, and mTORC2 to induce comprehensive blockade of the PAM pathway.9,10,11 As a multi-target PAM inhibitor, gedatolisib’s mechanism of action is highly differentiated from currently approved single-target inhibitors of the PAM pathway.11 Inhibition of only a single PAM component gives tumors an escape mechanism through cross-activation of the uninhibited targets. Gedatolisib’s comprehensive PAM pathway inhibition ensures full suppression of PAM activity by eliminating adaptive resistance cross-activation that occurs with single-target inhibitors. Unlike single-target inhibitors of the PAM pathway, gedatolisib has demonstrated equal potency and comparable cytotoxicity in PIK3CA-mutant and -wild-type breast tumor cells in nonclinical studies and early clinical data.

AIM ImmunoTech Reports Positive Mid-year Safety and Efficacy Data from Phase 2 Study Evaluating Ampligen® (rintatolimod) in Combination with AstraZeneca’s Imfinzi® (durvalumab) for the Treatment of Pancreatic Cancer

On July 28, 2025 AIM ImmunoTech Inc. (NYSE American: AIM) ("AIM" or the "Company") reported positive data in a mid-year 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 (the "DURIPANC" study) (See: ClinicalTrials.gov NCT05927142) (Press release, AIM ImmunoTech, JUL 28, 2025, View Source [SID1234654567]).

The DURIPANC study – which is a joint collaboration with AstraZeneca and Erasmus Medical Center ("Erasmus MC") in the Netherlands – is an investigator-initiated, exploratory, open-label, single-center study expected to enroll up to 25 subjects in the Phase 2 portion. A total of 14 subjects have been enrolled in DURIPANC as of the mid-year report. The primary objective of the study is the clinical benefit rate of the combination therapy; the secondary/exploratory objectives include assessing overall survival (OS), progression-free survival (PFS) and initiating immune-monitoring using available tissue biopsies and peripheral immune profiling.

Prof. Casper van Eijck, MD, PhD, of Erasmus MC, stated: "Our preliminary data suggests that the combination of Ampligen and durvalumab is well-tolerated in post-FOLFIRINOX pancreatic cancer patients, with encouraging preliminary survival data, especially given the historical difficulty of improving outcomes in this setting. Immunologic correlatives and further follow-up are essential to determine the biological activity and the durability of response. In addition, it will be important to identify which patients are most likely to benefit from the combination treatment, thereby personalizing therapy better and maximizing clinical outcomes."

See: DURIPANC, Mid-Year Interim Clinical Progress Update.

Pancreatic cancer has limited immunotherapy responsiveness, particularly in unselected populations. Following FOLFIRINOX, maintenance or second-line immunotherapies have historically shown limited survival benefit in comparison trials. Compared to these data, the DURIPANC study mid-year report shows continuing promising early signs of both no significant toxicity and superior PFS and OS:

No significant toxicity, an encouraging safety profile for a post-chemo setting;
~21% of patients have PFS >6 months (3/14), with an additional 21% not yet progressed; and
OS >6 months in the majority (64%) of eligible patients-better than expected in this setting.
AIM ImmunoTech CEO Thomas K. Equels stated: "Data from Ampligen as a maintenance monotherapy was extremely positive when compared to existing therapeutic approaches. DURIPANC builds on that foundation and these results suggest a clear path forward and identify a promising potential benefit of combining the selective innate immune activation of Ampligen with the checkpoint inhibition of durvalumab in pancreatic cancer maintenance therapy. I am hopeful that pending immune-monitoring data analysis by Prof. van Eijck and the team at Erasmus Medical Center will identify additional mechanistic insights or predictive biomarkers in this potentially groundbreaking clinical trial, bringing hope for a future therapy for this highly lethal and clearly unmet medical need that kills more than 100,000 people in the American and European Union markets each year, and more than 500,000 worldwide."

AIM’S Pancreatic Cancer Profile

The DURIPANC study is the culmination of several years of focus by AIM on the development of Ampligen for the treatment of pancreatic cancer. Since 2017, more than 50 pancreatic cancer patients received treatment with Ampligen as an immuno-oncology mono-therapy under a Dutch government-approved Compassionate Use/Early Access Program at Erasmus MC. Prof. van Eijck was the lead investigator and the EAP has produced a number of detailed analyses in both abstracts and peer-reviewed medical research publications:

Rintatolimod (Ampligen) Enhances Numbers of Peripheral B Cells and Is Associated with Longer Survival in Patients with Locally Advanced and Metastasized Pancreatic Cancer Pre-Treated with FOLFIRINOX: A Single-Center Named Patient Program
Treating Pancreatic Ductal Adenocarcinoma Patients with Rintatolimod: Hitting Two Targets with One Arrow?
Rintatolimod in Advanced Pancreatic Cancer Enhances Antitumor Immunity through Dendritic Cell-Mediated T-Cell Responses
Based on these strong results suggesting Ampligen’s potential effectiveness as a pancreatic cancer monotherapy, in January 2023 the Company entered into Clinical Agreements with AstraZeneca and Erasmus MC for the investigator-initiated DURIPANC clinical trial to study the potential combination therapy of Ampligen and Durvalumab, a PD-L1 checkpoint inhibitor.

In order to protect what has the potential to be a valuable long-term benefit for stockholders, AIM has developed an intellectual property plan specific to pancreatic cancer that includes a recently issued U.S. patent for Ampligen as an oncology treatment in combination with an anti-PD-L1, extending protection to August 9, 2039, as well as orphan drug designations in pancreatic cancer in both the United States and the European Union granting years of market exclusivity to AIM for Ampligen post-commercial approval.
