Personalized cellular therapy achieves complete remission in 90 percent of acute lymphoblastic leukemia patients studied
The new data, which builds on preliminary findings presented at the American Society of Hematology’s annual meeting in December 2013, include results from the first 25 children and young adults (ages 5 to 22) treated at the Children’s Hospital of Philadelphia and first five adults (ages 26 to 60) treated at the Hospital of the University of Pennsylvania. Twenty-seven of the 30 patients in the studies achieved a complete remission after receiving an infusion of these engineered “hunter” cells, and 78 percent of the patients were alive six months after treatment. “The patients who participated in these trials had relapsed as many as four times, including 60 percent whose cancers came back even after stem cell transplants. Their cancers were so aggressive they had no treatment options left,” said the study’s senior author, Stephan Grupp, MD, PhD, a professor of Pediatrics in Penn’s Perelman School of Medicine and director of Translational Research in the Center for Childhood Cancer Research at the Children’s Hospital of Philadelphia…
