Studien-Informationen

Brief Summary:

The safety run-in part of the study aims to evaluate the safety and tolerability of

blinatumomab alternating with low-intensity chemotherapy. The phase 3 part of the study aims

to compare event-free survival (EFS) and overall survival (OS) of participants receiving

blinatumomab alternating with low-intensity chemotherapy to EFS and (OS) of participants

receiving standard of care (SOC) chemotherapy.

Ein-/Ausschlusskriterien

includes experts in the field of adult leukemia with experience with the use of

blinatumomab, the global development lead for blinatumomab and the medical monitor of

the study.

Disease or if liver involvement with leukemia); exception for participants 40 to < 55

years of age if they have a comorbidity listed above: severe liver disease such as

cirrhosis stage 2 with portal hypertension or history of esophageal variceal bleeding

and AST/ALT > 10 x ULN (liver cirrhosis must be confirmed by biopsy)

hepatitis C virus (HCV) (eg, HCV RNA [qualitative] is detected).

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.

Studien-Arme

  • Experimental: Safety Run-in: Blinatumomab alternating with low-intensity chemotherapy
    The safety run-in will be performed prior to initiating the phase 3 randomized part of the study. This safety run-in is to evaluate the safety and tolerability of blinatumomab alternating with low-intensity chemotherapy. The safety run-in also evaluates a shorter dose step interval from (4 days instead of 7 days) and a 1-week (instead of 2-week) drug free interval between blinatumomab cycles. Blinatumomab will be infused at a lower dose for 4 days and increase to a higher dose on Day 5 of the infusion for the remainder of the infusion.
  • Experimental: Phase 3: Blinatumomab alternating with low-intensity chemotherapy
    Participants will receive blinatumomab alternating with low-intensity chemotherapy.
  • Active Comparator: Phase 3: Standard of care (SOC) chemotherapy
    Participants will receive 1 of 2 SOC chemotherapy regimens (GMALL or HyperCVAD) per investigator's choice.

Geprüfte Regime

  • Blinatumomab (Blincyto®):
    Continuous intravenous (cIV) infusion
  • Low-intensity chemotherapy regimen:
    Intravenous (IV), oral (PO), subcutaneous (SC), or intrathecal (IT) administration.
  • SOC chemotherapy regimen:
    Intravenous (IV), oral (PO), subcutaneous (SC), or intrathecal (IT) administration.
