Dr. Ben Carson's recently announced presidential campaign means he won't have time to help lead Baltimore company Vaccinogen anymore, the company said Tuesday.
Carson stepped down from his role as chairman of Vaccinogen's board of directors. Andrew L. Tussing, the company's CEO, will replace him.
"I continue to believe Vaccinogen's patient-specific cancer vaccine platform truly has the potential to revolutionize cancer treatment and serve the greater good," Carson said in a statement. "Despite my passion for this extremely important innovation, I now must focus my full attention on my campaign and serving the American people."
Carson formally announced Monday he would seek the Republican nomination for president in 2016.
Vaccinogen is developing a vaccine that trains the immune system to fight colon cancer tumor cells. The company moved to Fells Point from Frederick in February.
Carson joined the board as chairman in August.
