Vancouver, Canada – August 4, 2025 – Onco-Innovations Limited (CBOE CA: ONCO) (OTCQB: ONNVF) (Frankfurt: W1H, WKN: A3EKSZ) ("Onco" or the "Company”) is pleased to announce it has entered into a Start-Up Agreement with Avance Clinical Pty Ltd (“Avance”), a leading contract research organization, to initiate key regulatory and clinical documentation, such as the scientific summaries and trial plans required to eventually apply for approvals for human testing, for the Company’s lead candidate, the exclusively licensed Polynucleotide Kinase Phosphatase (PNKP) inhibitor (the “Technology”), a first-in-class, polymer-encapsulated therapy. The work is expected to lay the groundwork for regulatory clearance and clinical trial readiness.

Under the agreement, Avance will provide expert clinical and regulatory support to Onco as the Company pursues trials targeting advanced-stage cancers with PTEN[1] or SHP-1[2] deficiency. Deliverables include the development of an Investigator’s Brochure summarizing the drug’s preclinical performance, the authorship of a detailed clinical trial protocol, and independent medical and statistical review related to a Phase I clinical study. These documents are essential prerequisites for regulatory agencies to evaluate the safety and scientific merit of an investigational therapy. 

Additionally, Avance will perform a nonclinical gap analysis, reviewing existing data to identify any remaining preclinical work required for a future Investigational New Drug (IND) application. The agreement also covers the planning and preparation of a pre-IND meeting with the with the U.S. Food and Drug Administration (FDA), a critical regulatory milestone aimed at aligning Onco’s trial design with agency expectations and reducing development risk.

“This collaboration with Avance is another example of our progress as we continue to move towards discovery to clinical development. It’s about turning promising science into a real clinical opportunity for patients. Their regulatory and operational expertise will be essential in shaping a trial that is not only scientifically sound but also built for execution. We’re excited to enter this collaboration with Avance,” stated Thomas O’Shaughnessy, CEO of Onco-Innovations.

[1] PTEN is a tumor suppressor gene that helps prevent uncontrolled cell growth by regulating signals that control cell division and survival. Mutations or loss of PTEN function can disrupt this balance and lead to tumor formation. See PTEN gene – MedlinePlus Genetics: https://medlineplus.gov/genetics/gene/pten

[2] SHP-1 is a protein that helps control cell signaling, acting as a “brake” on pathways that promote cell growth and survival. When SHP-1 is missing or inactive, these signals can become overactive, contributing to cancer development.
