Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will explore 2 different doses of inotuzumab ozogamicin including the dose that is approved and a lower dose. The main purpose of this study is to evaluate whether a dose of inotuzumab ozogamicin, lower than the approved dose, could be recommended for adult patient with relapsed or refractory ALL who may be at higher risk for severe liver problems after inotuzumab ozogamicin treatment and stem cell transplant (a potentially curative therapy that can replace cancer cells with healthy cells). Efficacy and safety of the 2 doses will be evaluated.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The study will be conducted in 2 phases: a run in phase and a randomized phase.

Run in phase: a total of up to 22 patients will be enrolled to receive the starting dose of 1.2 mg/m2/cycle (dose level 2). A Simon Two Stage optimal design will be used. If acceptable efficacy (CR/CRi and MRD negativity) is observed in the run in phase, the study will enter the randomized phase.

Randomized phase: if acceptable efficacy is observed in the run in phase, the study will enter the randomized phase. A total of approximately 80 patients will be randomized (1:1) to 1 of 2 dose levels of inotuzumab ozogamicin (40 patients per dose level).

Inotuzumab ozogamicin-dose level 1

Intervention Type DRUG

Female subjects of nonchildbearing potential must meet at least 1 of the following criteria:

1. Achieved postmenopausal status, defined as follows: cessation of regular menses for at least 12 consecutive months with no alternative pathological or physiological cause; and have a serum follicle stimulating hormone (FSH) level confirming the postmenopausal state;
2. Have undergone a documented hysterectomy and/or bilateral oophorectomy;
3. Have medically confirmed ovarian failure. All other female subjects (including female subjects with tubal ligations) are considered to be of childbearing potential.
