- Topline data expected in mid-2025 - SOUTH SAN FRANCISCO, Calif., April 30, 2025 (GLOBE NEWSWIRE) -- Vaxart, Inc. (Nasdaq: VXRT) today announced that it completed enrollment of its Phase 1 clinical trial evaluating its second-generation oral norovirus vaccine constructs head-to-head against its first-generation constructs. “Completing enrollment in this trial bring us one step closer in our development of a norovirus vaccine, where there is a significant unmet need,” said Steven Lo, Chief Executive Officer of Vaxart. "We are excited about the potential of our second-generation oral norovirus vaccine constructs that we believe may be more potent than our first-generation constructs. We look forward to sharing the topline data in mid-2025.” The Phase 1 trial is an open label, dose ranging clinical study designed to evaluate Vaxart’s second-generation oral norovirus vaccine constructs head-to-head against its first-generation constructs. The study will measure safety and immune parameters that have correlated to protection in the completed norovirus challenge study. Norovirus is a leading cause of acute gastroenteritis worldwide, and Vaxart's oral vaccine candidate aims to provide a convenient and effective solution for this significant public health challenge. An independent Data and Safety Monitoring Board (DSMB) conducted a pre-planned interim safety data review and recommended the study to continue without any modifications. If the Phase 1 trial is successful, and assuming a partnership or other funding, Vaxart expects to conduct a Phase 2 safety and immunogenicity study that could potentially begin as early as the second half of 2025, followed by an End of Phase 2 meeting with the U.S. Food and Drug Administration (FDA). A Phase 3 trial could then begin as early as 2026.

(Nasdaq: VXRT) today announced the initiation of a Phase 1, open label, dose ranging clinical trial evaluating its second-generation oral norovirus vaccine constructs head-to-head against its first-generation constructs. “We are pleased to initiate a Phase 1 trial for our oral bivalent norovirus vaccine, delivered in a pill formulation, which will seek to demonstrate improved immune responses of our second-generation constructs,” said Steven Lo, Chief Executive Officer of Vaxart. “As norovirus continues to spread across the United States and globally, it has never been more important to address this urgent public health need. With no currently approved vaccines against norovirus, we are committed to advancing what we believe is the most promising norovirus vaccine candidate in clinical development and look forward to reviewing the topline data that is expected as early as mid-2025.” The Phase 1 trial is an open label, dose ranging clinical study designed to evaluate Vaxart’s second-generation oral norovirus vaccine constructs head-to-head against its first-generation constructs.

Safety Committee approval based on positive Phase 1 safety data demonstrating the combination therapy to be generally well-tolerated with no severe treatment-related adverse events or dose-limiting toxicities Enrollment for Phase 2 expected to commence imminently Feb. 05, 2025 - AIM ImmunoTech Inc. (NYSE American: AIM) (“AIM” or the “Company”) today announced Safety Committee approval to proceed with the Phase 2 portion of the Phase 1b/2 clinical trial involving AIM’s Ampligen® (rintatolimod) and AstraZeneca’s anti-PD-L1 immune checkpoint inhibitor Imfinzi® (durvalumab) in the treatment of late-stage pancreatic cancer (“DURIPANC”). DURIPANC is an investigator-initiated, exploratory, open-label, single-center study in the Netherlands at the Erasmus Medical Center (“Erasmus MC”). The approval to proceed to Phase 2 was granted following the Safety Committee’s review of the complete Phase 1 safety data, which found the combination therapy to be generally well-tolerated with no treatment-related severe adverse events or dose-limiting toxicities. AIM CEO Thomas K. Equels stated: “Patients with late-stage pancreatic cancer have very few options. This is a lethal malignancy that kills approximately 50,000 Americans every year and there is no effective therapy. It is one of the highest unmet needs in oncology, and we are excited to see this clinical study at Erasmus Medical Center in the Netherlands move to Phase 2. Ampligen is believed to reprogram the immune system to enhance the cellular response, and this combination study with Imfinzi is part of our broader strategy to explore these effects in combination with synergistic anti-cancer agents, including checkpoint inhibitors.” Prof. Casper H.J. van Eijck, MD, PhD, Pancreato-biliary Surgeon at Erasmus MC and Coordinating Investigator for the DURIPANC study, commented: “We have observed improvements in quality of life and we saw no toxicity at all – with ‘quality of life’ recognized as an indicator of stable disease. As a comparison, approximately 80% of patients at Erasmus MC with similar disease, but who did not receive the treatment, showed disease progression after only three months. While this new data is extremely preliminary, it is also encouraging since some patients with metastatic pancreatic cancer still have stable disease for 15 or more months after starting FOLFIRINOX, including six or seven months of maintenance therapy. By analyzing blood samples and tumor biopsies taken at different time points before and after the start of immunotherapy, we will obtain crucial insights into several aspects of treatment response, immune dynamics and tumor evolution.” Up to 25 patients are expected to be enrolled in the Phase 2 portion of DURIPANC. Six patients from Phase 1 will be included in Phase 2, as per the protocol and based on their Phase 1 participation. Continued enrollment is expected to begin soon.
