"We are excited to welcome Dr. Berk as the Company's Chief Medical Officer as we continue to progress TriKE™ through the clinic.

His "Next Generation" TriKE™ is a first-in-class platform with the potential to disrupt the existing immuno-oncology treatment landscape in a significant way. The data generated for GTB-3550 in AML and MDS thus far are highly encouraging, which is already demonstrating promising signs of clinical benefit in addition to a strong safety profile across the first nine evaluable patients," said Dr. Berk. "The flexibility and versatility of the TriKE™ platform represents a revolutionary opportunity to deliver patients, what the data has so far shown, to be a safe and effective, off-the-shelf, potent therapeutic. I am delighted to have the opportunity to work alongside Dr. Miller, his team, and the entire GT Biopharma team in this new capacity at such a pivotal time for the Company."
