Leukemia shot could replace long IV drips

This study tests if a shot (subcutaneous) of the drug blinatumomab works as well as the standard IV drip for adults with a certain type of leukemia (Ph-negative B-cell ALL). About 560 people who are in remission after initial chemo will get either the shot or the IV, along with more chemo. The main goal is to see if survival is similar between the two groups.
