"Taking the time to navigate this opportunity with proper care and diligence is a step that demonstrates our commitment to the best interests of our investors, partners, shareholders, and potential future patients," remarked Sean Carrick, CEO of NBIO. "No one likes delays, but patience and care at this critical stage is necessary in maximizing patient outcomes and long-term shareholder value. We want to be careful not to make hasty decisions while exploring all options.

This announcement comes as the Company prepares for a Phase II trial that follows a very successful Phase I trial-where safety at five ascending dose cohorts was observed-involving 15 patients who received PTB for various types of brain tumors. The most common and most challenging to treat tumor type in the trial was Glioblastoma. 12 of 15 patients had this diagnosis.

There were no dose-related toxicities. Overall, the study found that single agent Pritumumab is safe up to a dose of 16.2 mg/kg every 7 days in brain tumor patients. One partial response showed a 98.0% and 40.8% reduction in 2 tumor lesions for 21 months on study.

Mr. Carrick continued, "Phase I demonstrated an excellent safety profile at various doses. Phase II will be focused on clinical outcomes, and we are taking no shortcuts. We have been in discussions with potential Phase II study sites to ensure patients are being actively recruited and the most efficient process in place once we are ready to begin dosing."

Management anticipates that some research sites will open for the start of Phase II testing late this summer with actual patients involved later in 2024.
