Exclusion Criteria:

• Active central nervous system (CNS) leukemia not resolved with IT chemotherapy during screening.

Active hepatitis B and C based on the following results:

• positive for hepatitis B surface antigen (HepBsAg) (indicative of chronic hepatitis B or recent acute hepatitis B)
• negative HepBsAg and positive for hepatitis B core antibody: negative HBV DNA by PCR result is necessary to enroll.

• positive Hepatitis C virus antibody (HepCAb): negative hepatitis C virus RNA by PCR result is necessary to enroll.

  • Participant with symptoms and/or clinical signs and/or radiographic and/or sonographic signs that indicate an acute or uncontrolled chronic infection.
  • Cancer chemotherapy for this newly diagnosed B cell ALL before the start of protocol-required therapy with the exception of IT chemotherapy or pre-phase chemotherapy.
