• CNS Portfolio Strategy Activated: The Company is actively pursuing discussions with potential partners regarding the acquisition of additional CNS assets synergistic with ONP-002 and the Company's intranasal delivery platform
• US Clinical Trial Strategy: Engaged DUCK FLATS Pharma as its U.S. IND readiness and regulatory execution partner to support FDA-facing preparation and clinical trial design
• Annual Report Filed: Form 10-K filed for fiscal year ended December 31, 2025
  
  
  
  

2026 STRATEGIC PRIORITIES

• Enroll and dose patients in the Phase IIa clinical trial of ONP-002 in Australia
• File an IND with the FDA to enable a U.S.-based clinical trials
• Advance CNS portfolio expansion strategy by evaluating and pursuing synergistic asset acquisition opportunities
  
  
  
  

"2025 was the year we reset this company — financially, operationally, and strategically," reported Janet Huffman, the Company's Chief Executive Officer. "We raised capital, restored compliance, resolved a material legacy liability, and built the partnerships and infrastructure to compete at a higher level. None of that was easy, and none of it was accidental. It was the result of disciplined execution by a team that believes deeply in what ONP-002 can do for the 69 million people worldwide who suffer concussions every year with no approved pharmacological treatment available to them. 2026 is not about resetting. It is about executing. We are in the clinic. Patients will be dosed. And we are actively exploring the expansion of our CNS platform."
