VANCOUVER, BC / ACCESS Newswire / April 28, 2026 / Onco-Innovations Limited (CBOE CA:ONCO)(OTCQB:ONNVF)(Frankfurt:W1H, WKN:A3EKSZ) ("Onco" or the "Company") announced, further to its news release dated April 21, 2026, the successful scale-up of key intermediates1 A83 and B4, representing an advancement in the Company's chemistry, manufacturing and controls (CMC) program supporting its lead nanoparticle-based PNKP inhibitor drug candidate, ONC010 (also referred to as PNKP Inhibitor Technology). These intermediates are essential components in the synthesis of A83B4C63, the active pharmaceutical ingredient (API) utilized in the Company's proprietary nanoparticle formulation of ONC010.
Conducted in collaboration with Dalton Pharma Services, the scale-up program successfully advanced both intermediates from laboratory-scale synthesis to intermediate-scale production, demonstrating robust process, reproducibility, and scalability.
The successful scale-up of A83 and B4 supports the Company's broader objective of establishing a reliable and scalable manufacturing pathway for ONC010, ensuring sufficient material supply for ongoing preclinical studies, formulation development, and IND-enabling activities. The program also advances key process optimization efforts designed to support future GMP manufacturing and clinical-stage production.
"This achievement represents an important step forward in de-risking our manufacturing strategy," said Thomas O'Shaughnessy, Chief Executive Officer of Onco-Innovations. "The successful scale-up of these critical intermediates strengthens the foundation of our CMC program and supports the continued advancement of ONC010 toward future first-in-human clinical studies."
Dalton Pharma Services, a North American CDMO with expertise in complex synthetic chemistry and pharmaceutical manufacturing, has played a central role in advancing process development and scale-up activities across the Company's program. The successful execution of the intermediate scale-up further validates Dalton's capabilities in supporting the development of complex drug substances and reinforces the strength of Onco-Innovations' integrated partner network.
The Company continues to advance additional CMC activities, including integrated synthesis of A83B4C63, analytical method development and qualification, and scale-up of its proprietary polymer platform. These efforts are being conducted in parallel with preclinical studies led by Nucro-Technics and clinical development planning in collaboration with Avance Clinical.
Collectively, these activities are designed to support a comprehensive IND-enabling program and position ONC010 for entry into first-in-human clinical trials.
