The management changes are effective as of April 12, 2022.

“Ronald’s passion, expertise and exceptional scientific leadership have been fundamental to Pyxis Oncology’s growth since its founding as an IO-focused target discovery company. The legacy and impact of his work has enabled Pyxis Oncology to successfully transition to a clinical stage company with our expansion into the ADC modality,” said Lara Sullivan, M.D., President and Chief Executive Officer. “I am incredibly proud of the remarkable research team that Ronald has built, and I know he will continue to be successful in his future endeavors.”

Dr. Sullivan continued, “I am excited for Jan to assume a larger leadership role at this important time for our company. His experience in preclinical and clinical development will be invaluable as we continue to mine the Pfizer FACT ADC platform and advance new therapeutics for those suffering from difficult-to-treat cancers. As we continue to grow, our expert team of leaders will steward our strategy of building a multi-asset multi-modality diversified oncology company."

Dr. Pinkas said, “I am eager to take on this expanded role as we are poised to deliver multiple potential catalysts over the next several months. I look forward to working with the talented team at Pyxis Oncology to continue building a deep pipeline of research and preclinical programs that will support the development of a range of novel and exciting therapeutics with significant potential to help underserved patients.”

Dr. Herbst added, “When I joined Pyxis Oncology in 2019, my goal was to lay a strong scientific foundation and lead our evolution to a clinical-stage company. Having accomplished that, the time is now right for me to take the next step in my own career journey. It has truly been a privilege to work with such a remarkable team of scientists and I look forward to following the Company’s progress and supporting Jan through this transition.”
