OGEN Oragenics Inc

Oragenics, Inc. (NYSE American: OGEN), a biotechnology company focused on developing novel intranasal therapies for brain-related conditions, today provided shareholders with an update on its strategic and financial progress for the first quarter of 2025. The Company has made meaningful advancements across regulatory, clinical, financial, and partnership initiatives, further positioning its lead therapeutic candidate, ONP-002, as a first-in-class solution for treating concussion.

“We believe ONP-002 is one of the most undervalued clinical assets in biotechnology today,” said Janet Huffman, Interim CEO of Oragenics. “With strong preclinical validation and clinical safety data, a scalable ONP-002 intranasal delivery system, and no current FDA-approved treatments for concussion, ONP-002 could redefine the standard of concussion care. Our Q1 progress — from regulatory submissions to our landmark partnership with BRAINBox — reflects a sharpened strategic focus and operational momentum. We’re energized by what’s ahead and remain committed to delivering long-term value for our shareholders.”

Key Accomplishments in Q1 2025

In the first quarter of 2025, Oragenics achieved several strategic and operational milestones:

• Industry Engagement & Awareness: Participated in the 12th Annual Brain Health Summit at Leigh Steinberg’s Super Bowl Party 2025, helping raise visibility for traumatic brain injury (TBI) and ONP-002’s potential therapeutic impact.
• Strategic Partnership: Established a collaboration with BRAINBox Solutions to combine diagnostic biomarkers with ONP-002’s intranasal delivery system, aiming to transform concussion treatment by enabling faster, more targeted care.
• Clinical Trial Advancements: Submitted the Investigator’s Brochure (IB) for the Phase IIa clinical trial in Australia, marking a key regulatory step. The trial is now publicly listed on ClinicalTrials.gov.
• Strengthened Financial Position: Raised approximately $5 million through a combination of dilutive and non-dilutive capital, including approximately $2.6 million via At-the-Market (ATM) equity financing and approximately $2.25 million through non-dilutive debt funding.
• Shareholder Communications: Announced that the 2025 Annual Shareholder Meeting will be held on May 2, 2025, with the preliminary proxy filed with the SEC on March 19, 2025.

ONP-002: An Undervalued Asset with First-Mover Advantage

Oragenics’ lead drug candidate, ONP-002, is a neuroprotective, anti-inflammatory compound administered intranasally for the treatment of concussion, classified as a mild traumatic brain injury (mTBI). ONP-002 is an intranasal therapeutic being developed for concussion and is designed to interrupt key biological pathways involved in inflammation, oxidative stress, and swelling following head trauma.

Although still in clinical development, ONP-002 represents a “silent asset” that has been significantly de-risked through extensive preclinical studies. These include cardiotoxicity, genotoxicity, and dose-ranging evaluations. In addition ONP-002 successfully completed a Phase I human study that was well-tolerated with no serious adverse events. With a novel formulation and scalable ONP-002 intranasal delivery system already in place, ONP-002 is ready for rapid and cost-effective progression through clinical phases.

Clinical and Regulatory Milestones Build Momentum

In late 2024 and early 2025, Oragenics finalized drug production for the Phase IIa clinical trial and submitted the Investigator’s Brochure to regulatory authorities in Australia. The trial has been officially listed on ClinicalTrials.gov, and the Company is now awaiting approval from the Human Research Ethics Committee (HREC), with first patient enrollment expected shortly thereafter.

“Reaching this stage of clinical preparation—especially with a commercial-ready delivery device and finalized drug product—positions us for rapid execution once regulatory clearance is received,” added Huffman.

Strategic Partnership with BRAINBox Solutions

In February, Oragenics formed a pivotal collaboration with BRAINBox Solutions, a diagnostics company pioneering biomarker-based concussion testing. This partnership pairs Oragenics’ intranasal therapeutic with BRAINBox’s diagnostic tools to create a smarter, faster, and more personalized approach to concussion care.

“This collaboration unites two emerging leaders in brain health—Oragenics in therapeutic innovation and BRAINBox in diagnostic excellence,” said Huffman. “Together, we are designing a smarter, faster approach to treating concussion that could set a new benchmark for the field.”

Increased Visibility and Market AwarenessBeyond industry events, Oragenics has made a concerted effort in recent months to engage investors, clinicians, and thought leaders through media, podcasts, and speaking opportunities. The Company’s outreach has focused on raising awareness around the scale of untreated concussion, the science behind ONP-002, and the lack of approved pharmacological options.

“We’ve worked diligently to educate the market—both the investment community and clinical stakeholders—about the game-changing potential of ONP-002,” said Huffman. “The response has been highly encouraging. It’s clear there is an unmet need, and the concept of a fast-acting, intranasal treatment resonates with physicians, patients, and investors alike.”

Financial Foundation and Capital Structure Improvements

In Q1 2025, Oragenics raised approximately $5 million in new funding through a balanced mix of equity and debt capital. This included approximately $2.6 million via ATM equity sales and approximately $2.25 million in non-dilutive debt financing. In addition, the Company submitted a grant request to the Department of Defense to secure non-dilutive capital in support of its concussion program. In Q4 2024, Oragenics also converted all outstanding Series A and B preferred shares to common stock, simplifying its capital structure and enhancing transparency for shareholders.

“This funding underscores our ability to secure capital through multiple channels and at critical moments,” Huffman stated. “It reflects growing confidence in our strategy and allows us to continue executing with discipline and focus.”

Operational Efficiencies and Governance Updates

As part of its disciplined approach to resource management, Oragenics implemented executive leadership changes in late 2024 that have meaningfully reduced fixed overhead costs. These moves ensure that capital is directed toward value-driving programs like ONP-002. The Company also confirmed that its 2025 Annual Shareholder Meeting will be held on May 2, 2025, with preliminary proxy materials filed in March.

Key Milestones Ahead

With strong positioning across clinical, operational, and financial fronts, Oragenics is preparing to advance ONP-002 through the next stage of development. The Company’s upcoming projected milestones include:

Milestone	Expected Timing
HREC approval in Australia	Q2 2025

Our Commitment to Long-Term Value Creation

As Oragenics enters a pivotal execution phase, the Company remains committed to advancing ONP-002 with urgency and precision. Its goal is to deliver a meaningful clinical breakthrough in concussion care and to generate long-term value for its shareholders.

“We are committed to seeing ONP-002 through to its full potential,” said Huffman. “With each milestone we reach, our conviction only grows stronger. This is more than a drug program—it’s an opportunity to change the standard of care for millions of patients. Our team is fully aligned, fully engaged, and determined to deliver results that matter for shareholders and society alike.”
