Over the past year, Oragenics has steadily advanced ONP-002 through the clinical pathway. Key steps included HREC approvals in Australia, selection of Southern Star Research as CRO, and plans for Phase IIb supported by a U.S.-based manufacturing agreement. Clinical-trial news, such as the Mar 10, 2026 HREC approval and earlier Phase II approvals in 2025, often produced modest price reactions, suggesting investors react incrementally to each development.
Historical Comparison
Past clinical-trial headlines (5 events) produced an average 2.94% move, showing typically moderate price sensitivity to development milestones.
Clinical news shows a progression from initial HREC approvals and manufacturing prep, through CRO selection and conference visibility, to operational steps like site initiation and trial activation for ONP-002.

FIRST SITE INITIATION VISIT COMPLETED IN AUSTRALIA
SARASOTA, Fla., March 12, 2026 (GLOBE NEWSWIRE) -- Oragenics, Inc. (NYSE American: OGEN), a clinical-stage biotechnology company pioneering brain-targeted therapeutics through proprietary intranasal delivery technology, today announced it has completed the first site initiation visit (SIV) for its Phase IIa clinical trial of ONP-002 in Australia. The visit marks the formal launch of clinical trial operations at the first of three planned trial sites in Australia, including completion of site staff training, protocol orientation, and site regulatory documentation.
The remaining two clinical trial sites are currently completing their Research Governance Office (RGO) reviews — the final administrative step required following Human Research Ethics Committee (HREC) approval before each site can activate to begin patient enrollment and dosing. The Company expects these reviews to be completed in the near term, at which point all three sites will be positioned to enroll patients.
The Phase IIa trial initiation follows the Company's receipt of HREC approval earlier this year, which represented the final regulatory clearance required to commence clinical site contract finalization, activation, and onboarding.
PHASE IIA CLINICAL TRIAL OVERVIEW
The Phase IIa trial is a randomized, placebo-controlled study evaluating the safety, tolerability, and preliminary clinical signals of ONP-002 in patients presenting with acute concussion and mild traumatic brain injury. Key design parameters include:
- Enrollment target: 40 patients across three Australian clinical sites
- Dosing window: First dose administered within 12 hours of concussion onset
- Primary endpoints: Safety (adverse events, nasal examinations), neurocognitive follow-up assessments, and participant compliance/tolerability
- Trial status: First SIV complete; two remaining sites in RGO final review prior to activation
"We said we would advance ONP-002 into patients in Australia — and that process is now underway. Our first site is trained, operational, and ready to enroll. The remaining sites are completing their final governance reviews, and we expect them to follow shortly. This is the kind of measured, disciplined execution that clinical development demands, and our team is delivering. Patient dosing is the next step, and we are ready." — Chief Executive Officer, Janet Huffman.
"Site initiation marks the transition from regulatory preparation to active clinical operations. Our investigators are trained on the protocol, safety procedures are in place, and our CRO is coordinating operations across all three sites. The RGO review process at the remaining sites is proceeding as expected. We anticipate completing site activation across all three locations in the near term and beginning patient enrollment shortly thereafter."
— Chief Medical Officer, Dr James Kelly M.D.
ABOUT ONP-002
ONP-002 is a first-in-class intranasal neurosteroid in Phase IIa clinical development for the treatment of concussion and mild traumatic brain injury. Unlike current approaches limited to symptom management and rest, ONP-002 is designed to interrupt the neuroinflammatory cascade triggered by brain trauma — reducing neuroinflammation, oxidative stress, and cerebral edema at the source. Phase 1 clinical trials in 40 patients demonstrated ONP-002 was safe and well-tolerated across all dose levels with zero serious adverse events (SAEs). There are currently no FDA-approved pharmacological treatments for concussion or mTBI.
