Onco-Innovations Initiates Polymer Process Development and Characterization Program for ONC010

VANCOUVER, BC / ACCESS Newswire / June 30, 2026 / Onco-Innovations Limited (CBOE CA:ONCO)(OTCQB:ONNVF)(Frankfurt:W1H, WKN: A3EKSZ) ("Onco" or the "Company") is pleased to announce, further to its news release dated June 23, 2026, the initiation of polymer process development and analytical characterization activities being conducted by Nanosoft Polymers ("Nanosoft") in support of ONC010, the Company's lead nanoparticle-formulated Polynucleotide Kinase Phosphatase ("PNKP") inhibitor.

Current activities include polymer synthesis optimization, characterization methodology development, molecular weight assessment, polydispersity evaluation, purification strategy refinement and manufacturing scalability assessments. These efforts are intended to establish a robust and reproducible polymer manufacturing process capable of supporting future formulation development and technology transfer activities. The work forms a key component of the Company's chemistry, manufacturing and controls ("CMC") strategy and is intended to support the development of a scalable, reproducible, and analytically characterized polymer platform for future formulation, manufacturing, regulatory and clinical development activities.

"The initiation of this work with Nanosoft represents an important step in strengthening the manufacturing and formulation foundation of ONC010. Their specialized expertise in polymer science and nanoparticle drug delivery complements the work being performed by our broader development team and is helping us establish a more scalable and reproducible pathway toward future GMP manufacturing and clinical development," stated Thomas O'Shaughnessy, Chief Executive Officer of Onco-Innovations.

Nanosoft was recently engaged to augment the Company's existing manufacturing and development ecosystem with specialized expertise in polymer synthesis, nanoparticle drug delivery, formulation development, analytical characterization, purification strategies and manufacturing scale-up. Since initiation of the collaboration, Nanosoft has been advancing process development activities designed to strengthen the technical foundation of the ONC010 formulation platform while supporting future GMP manufacturing readiness.

The Company believes these activities are particularly important given the central role that polymer performance, consistency and characterization play in nanoparticle-based therapeutic development. Establishing a well-defined polymer platform is expected to support future manufacturing reproducibility, product quality, formulation performance and regulatory preparedness.

"The successful development of nanoparticle-based oncology therapies requires rigorous polymer characterization and process understanding. Nanosoft's work in polymer process development and analytical characterization is strengthening an important component of the ONC010 platform and supports our broader objective of advancing a high-quality therapeutic candidate toward clinical evaluation, " stated Dr. Islam Mohamed, Chief Medical Officer of Onco-Innovations.
