Summary
Brief summary
The primary objective of this phase 1b study is to evaluate the safety and tolerability of blinatumomab and AMG 404 in combination in adults with R/R B-ALL and to estimate the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of AMG 404 when combined with continuous intravenous infusion (cIV) blinatumomab.
