Brief Summary

The purpose of this phase 2/3 study is to confirm the recommended doses and to evaluate the safety and pharmacodynamics of Calaspargase pegol for the treatment of adult patients with Philadelphia-negative Acute Lymphoblastic Leukemia.

Detailed Description

The study will be conducted in 2 parts. Part 1 is a dose confirmation run-in period. Part 2 will enroll the remaining participants at the dose as confirmed in Part 1.
